Description

TECHNICAL FIELD The present invention relates to a container-detachable mixer.

2. Description of the Related Art A mixer of this type is constructed as shown in FIG.
On the orbiting table 1 which is revolved in the direction of arrow A, the pot mounting table 2 which is revolved in the direction of arrow B is mounted.
Is provided. Pin 3 on the pot table 2
A buckle 4 that is rotatable around the center and a arm 7 that is rotatably supported by a screw shaft 5 at an intermediate portion and has a base end that is rotatable around a pin 6 between a solid line position and an imaginary line position. Has been.

During operation, the lidded container 8 is placed on the pot mounting table 1 and the screw shaft 5 is tightened while the tip of the arm 7 is engaged with the buckle 4 so that the lidded container 8 becomes the pot mounting table 1. It is locked so as to rotate together.

When the operation for a predetermined time is completed, the screw shaft 5 is loosened and the container 8
Is removed from the pot mounting table 1, the lid 9 is removed, and the raw material in the container 10 is taken out.

Problems to be Solved by the Invention In such a conventional configuration, there is a problem that the attachment / detachment of the lid 9 to / from the container 10 and the attachment / detachment of the container 10 to / from the pot mounting table 1 cannot be automated.

An object of the present invention is to provide a mixer having a structure suitable for automation.

Means for Solving the Problems The mixer of the present invention is screwed to a pot mounting table that rotates on a revolution table and an orbiting upper member that rotates integrally with the orbiting table, and the pot mounting tail mounting surface. Toward and away from the screw shaft, the container lid rotatably supported at the tip of the screw shaft, and the opening is closed by the container lid interposed between the container lid and the pot mounting table. A container body that is pressed and locked to the pot mounting table side and a lid attaching / detaching device that has a detachable chuck at the upper end of the screw shaft and that engages with the screw shaft to drive the screw shaft to rotate are provided. It is characterized by

Operation According to this configuration, the container body whose upper opening is left open is placed on the pot mounting table, and the screw shaft is rotated by the lid attaching / detaching device to lower the container lid. With the container lid attached to the tip of the screw shaft in contact with the opening of the container body, the rotational drive of the screw shaft is stopped to obtain a state in which the container body does not move upward. As a result, the container body is locked to the pot mounting table while the opening of the container body is closed by the container lid.

When the operation is completed, the screw shaft is rotated by the lid attaching / detaching device to raise the container lid, and the container body with the opened lid can be taken out from the pot mounting table.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. It should be noted that components having the same functions as those in FIG.

1 and 2 show the mixer of the present invention. As shown in the perspective view of FIG. 3, the revolution table 1 is a shaft supported by a revolution lower bearing 11 and a revolution upper bearing 12.
It is fixed to 13, and is driven by a revolution motor 16 via a revolution pulley 14 and a belt 15. The orbiting table 1 is provided with a pot mounting table 19 supported by a lower rotating bearing 17 and an upper rotating bearing 18, and the pot mounting table 19 is a planetary gear 20 for rotation, a central gear 21 for rotation, and a rotation center gear 21. It is driven by a rotation drive motor 24 via a drive gear 22 and a belt 23. The pot mounting table 19 is provided with a cutout portion 28 in a pot receiving portion 27 that supports the protrusions 26 formed on both sides of the container body 25.

The rotation upper bearing 18 supports the female screw 31 via the bearing 30 on the revolution upper table 29 as the revolution upper member,
A screw shaft 32 is screwed into this female screw 31. A container lid 34 is rotatably attached to the lower end of the screw shaft 32 via a bearing 33.

The outer sides of the orbiting table 1 and the pot mounting table 19 are covered with an outer case 35, and a part of the container body 25 is covered with the outer case 35.
An outlet 36 for taking in and out is formed. The outlet 36 is closed by a shutter 37 during operation.

The screw shaft is located outside the outer case 35 and above the outlet 36.
A lid attaching / detaching device 38 that engages with 32 and rotates the screw shaft 32 is provided.

With this configuration, the motor 39 is operated to open the shutter 37 via the gear 40 and the rack 41, and the pair of support arms 42 supporting the container body 25 from the outlet 36 are placed on the pot mounting table 19. To enter. When the support arm 42 is lowered when the position of the pot receiving portion 27 is reached, the container body
25 transfers from the support arm 42 to the pot receiving portion 27 and projects.
26 engages with the notch 28. The support arm 42, which has completed the transfer of the container body 25, retracts to close the shutter 37.

Next, the lifting motor 43 is operated to chuck the lid attaching / detaching device 38.
44 is engaged with the screw shaft 32. When the chuck 44 is rotated to feed the screw shaft 32 downward, the container lid 34 is pressed against the opening of the container body 25 on the pot mounting table 19 to close the opening of the container body 25. Lifting motor 43
When the lid mounting device 38 is raised by reversing the
And the screw shaft 32 are disengaged from each other, and the container lid 34 is maintained in a state of closing the container body 25.

When the motors 16 and 24 are operated in this state, the container body 25 locked to the pot mounting table 19 revolves around the revolution table 1 while revolving on the revolution table 1.

When the operation for a predetermined time is completed, the lid attaching / detaching device 38 is operated to rotate the screw shaft 32 in the ascending direction, and the locking of the container body 25 to the pot mounting table 19 is released. Next, the shutter 37 is opened and the supporting arm 42 that has entered is lifted to lift the container body 25 from the pot receiving portion 27,
42 is retracted to the outside of the outer case 35, the container main body 25 is taken out, the container main body 1 is inverted, and the raw material therein is discharged.

As described above, by operating the lid attaching / detaching device 38, the opening of the container body 25 is closed by the container lid 34, and the container body 25 is locked to the pot mounting table 19 side. The container lid 34 can also be removed by operating the lid attaching / detaching device 38, and the structure is suitable for automatic operation.

EFFECTS OF THE INVENTION As described above, according to the present invention, the screw shaft that is screwed into the revolving upper member that rotates integrally with the revolving table and that moves out and back toward the mounting surface of the pot mounting table, and the tip of the screw shaft. A container lid rotatably supported on the container, and a container which is interposed between the container lid and the pot mounting table, the opening is closed by the container lid, and is pressed and locked to the pot mounting table side by a screw shaft. Since the main body and the lid attaching / detaching device that has a detachable chuck at the upper end of the screw shaft and engages with the screw shaft to drive the screw shaft to rotate, the opening of the container body is opened by the operation of the lid attaching / detaching device. When the container lid is closed and the container main body is locked to the pot loading table side, this locking can be released and the container lid can be removed by operating the lid attaching / detaching device, and the operation operation can be automated. You can
