  Further, the material input port (69) positioned in the regular rearward state (the use state of the mixer) of the safety cover (66) has an arc shape corresponding to the plan view as shown in FIGS. The lid plate (72) formed can be sealed from behind. (73) is a back wall plate that is integrally suspended so as to cross the back of the safety cover (66) from the lower surface of the stirring action box (Ab). The horizontal adjustment screw ７４ (74) supports the lid plate (72) of the material input port (69).

  In that case, the rear end portion of each adjustment screw rod (74) is fastened to the back wall plate (73) by the fixing nut (76) through the elevating adjustment long hole (75) opened in the back wall plate (73). Therefore, the forward and backward operation and the raising / lowering operation of each adjustment screw 杆 (74) can be performed to adjust the lid plate (72) at the front end to the sealed state of the material input port (69).

  (77) is a horizontal support bar that is fixedly mounted horizontally on the lower end of the back wall plate (73). As shown in FIGS. 11 to 13, this bar protrudes laterally outward from the stirring action box (Ab). A pair of left and right chain bolts (78) are fastened and integrated at both ends, and a shock absorber (79) attached to an intermediate portion of the support bar (77) is also connected to the mixer body frame (M) side. The ball receiving frame (6) is in a positional relationship from above.

Similarly, (81) is a pair of left and right roller bearing plates projecting integrally forward from the upper half of the back wall plate (73) along the left and right sides of the stirring action box (Ab). It corresponds to the two roller bearing seats (32) of the enclosure cover (31) that forms the heating action box (Hb).

  In addition, a pair of upper and lower rolling rollers (83) is also mounted on the roller bearing plate (81) via a horizontal support shaft (82) so as to be freely rotatable, and the mixer body frame (M) While being engaged with the upper-side lift guide rail (8) on the side, it can roll up and down along this.

  Next, regarding the raising / lowering operation mechanism (L) that brings the stirring action box (Ab) and the heating action box (Hb) close to or away from the ball (T) at once, (84) is the mixer body. A pair of upper sprocket wheels attached to the upper positions of the left and right side plates (4) in the frame (M) via a horizontal short support shaft (85) so as not to be lifted and lowered from the left and right side plates (4) It protrudes inward by the same distance as the above-mentioned rolling rollers (34) and (83).

  (P) is a pedal frame that is substantially U-shaped in a plan view and surrounds the mixer body frame (M) from the front side. As is apparent from FIGS. 15 to 17, the front end of the pedal frame is a horizontal tread (86). As compared with the horizontal frame, the rear ends of the left and right side frame pieces (87) are notched in the left and right side plates (4) of the mixer body frame (M) as a pair of roller bearing plates (88). It faces the pair of elevating guide groove rails (12) from the lateral outside.

  Then, a pair of upper and lower rolling rollers (90) are rotatably mounted on the pair of roller bearing plates (88) via a horizontal support shaft (89), and the mixer body frame While engaging with the lifting guide groove rail (12) on the (M) side, it can roll up and down along this.

  That is, the pedal frame (P) is engaged through the engagement action between the rolling roller (90) pivotally supported by the roller bearing plate (88) and the lifting guide groove rail (12) on the mixer body frame (M) side. Thus, the tread (86) can be moved up and down stably while maintaining the horizontal state. In addition, the raising / lowering stroke of the pedal frame (P) is set to about 90 mm as an example of illustration.

  Reference numeral (91) denotes a horizontal long support shaft fixedly mounted between the left and right sides of the roller bearing plate (88), and a pair of lower sprocket wheels (92) are attached in the vicinity of both ends thereof. In addition, similarly, a fixed arm (93) of an object to be detected, which is detected by the proximity sensor (17) described above, extends rearward and integrally from the intermediate portion of the support shaft (91). Therefore, it goes without saying that the lower sprocket wheel (92) and the fixed arm (detected object) (93) move up and down together with the roller bearing plate (88) of the pedal frame (P).

  Reference numeral (94) denotes a pair of left and right endless upper hanger chains which are temporarily connected to the upper sprocket wheel (84) from one end portion fastened to the chain bolt (78) of the support bar (77) in the stirring action box (Ab). ) And then the other end of the heating action box (Hb) fastened to the upper chain bolt (37) of the connecting stay (36) in the side view as shown in FIGS. It is almost inverted U-shaped.

  Similarly, (95) is a pair of left and right endless lower hanger chains, which are temporarily connected to the lower chain bolt (37) of the connecting stay (36) in the heating action box (Hb) from the lower sprocket wheel. After being wound around (92), the whole of the mixer body frame (M) up to the other end portion fastened to the bolt support stays (96) of the left and right side plates (4) via the chain bolt (97) As shown in FIGS. 6 and 7, it is bent in a substantially U shape in a side view.

  Therefore, when the pedal frame (P) is stepped on from the solid line in FIG. 15 as indicated by a chain line, the heating action box (Hb) incorporating the electromagnetic induction heater (H) becomes the lower stage on the mixer body frame (M) side. As soon as it descends along the elevating guide rail (9), the stirring action box (Ab) on which the drive source of the stirrer (A) is mounted resists its own gravity, and also on the mixer body frame (M) side. The stirring action box (Ab) and the heating action box from the ball (T) in a state where it rises along the upper lifting guide rail (8) and is received at the mid-high position of the mixer body frame (M). (Hb) is separated from each other.

  In that case, the fixed arm (detected object) (93) that protrudes backward and integrally from the support shaft (91) of the lower sprocket wheel (92) is also combined with the roller bearing plate (88) of the pedal frame (P). Since the position is not detected by the proximity sensor (17) on the mixer body frame (M) side, the operation of the mixer is automatically stopped with the power switch turned off.

  On the other hand, when the pedal frame (P) is raised and returned to the initial height position indicated by the solid line in FIG. 15, the fixed arm (detected object) (93) raised together with the pedal frame (P) The power switch detected by the proximity sensor (17) on the main body frame (M) side is in the ON state, which means that the mixer is in operation.

  In the state of use during operation, as apparent from FIGS. 1 to 3 and FIG. 6, the agitation box (Ab) is moved by its own gravity, and the upper elevating guide rail (8) on the mixer body frame (M) side. The heating action box (Hb) rises along the lower lifting guide rail (9) on the mixer body frame (M) side at the same time, and the midway height of the mixer body frame (M). The stirring action box (Ab) and the heating action box (Hb) come close to the ball (T) at the position, and the ball (T) is covered with the safety cover (66) from above. At the same time, it is surrounded by the electromagnetic induction heater (H) from below.

  As described above, the pedal frame (P) is substantially U-shaped in a plan view wider than the mixer body frame (M). As shown in FIGS. 15 to 17, a horizontal lever contact pin (98) protrudes inward and integrally from the middle part on the right side when viewed from the side.

  (99) is a cam lever of a fixed length that is received from below by the lever contact pin (98), and the left and right side plates of the mixer main body frame (M) by the base end fulcrum pin (100) whose rear end is horizontal. (4) A horizontal tip fulcrum pin (which is pivotally attached to either one (also on the right side) and also projects inward from the front end of the cam lever (99) through the right side plate (4). 101) holds the plate cam (102) rotatably. It goes without saying that the plate cam (102) is positioned within the frame of the mixer body frame (M).

  (103) is an elevating guide elongated hole of the tip fulcrum pin (101) penetrating the right side plate (4) of the mixer main body frame (M), and the arc-shaped cam elevating guide rail (104) arranged in parallel along this hole. Is attached and fixed to the inner surface of the right side plate (4).

  Similarly, (105) is a pin guide attached and fixed to the inner surface of the right side plate (4) in the mixer main body frame (M), and the plate cam (102) is connected to the cam contact pin (106) planted therein. If it hits, it will rotate and can be locked to the lower end surface of the cam elevating guide rail (104).

  In other words, once the tread plate (86) of the pedal frame (P) is stepped on as shown by the chain line from the solid line in FIG. 15, the cam lever (99), which has no receiving force by the lever contact pin (98), rotates downward. When the plate cam (102) held by the tip fulcrum pin (101) hits the pin (106) per cam of the pin guide (105) and rotates, the cam elevating guide rail (104) Therefore, the pedal frame (P) is held in the lowered state unless the stepping operation is applied again.

  Then, when the stepping plate (86) of the pedal frame (P) in the lowered state is stepped on again from the solid line in FIG. 16 as indicated by the chain line, the plate cam (102) is also moved to the pin per cam (105) of the pin guide (105). 106), the cam lever (99) is pushed up by the lever contact pin (98) by itself, and the cam lever (99) is released. It will return to the rising state.
