Two ends of the rear side sliding groove are respectively provided with a limiting block, the front side and the rear side of the extraction cup mechanism 31 are respectively arranged in the front side sliding groove 304 and the rear side sliding groove 305 in a sliding manner, and the limiting blocks can limit the sliding range of the extraction cup mechanism 31. The capsule extraction head 5 is erected in the middle of the cup throwing track 30, and the coffee capsule is moved to or from a position corresponding to the capsule extraction head by the cup to be extracted mechanism. When the extraction cup mechanism 31 slides to the right side limiting block from the beginning end D1 of the guide rail, the coffee capsule delivered by the coffee machine lifting mechanism can be received and then delivered to the lower part of the capsule extraction head, and after the coffee is brewed, the extraction cup mechanism drives the coffee capsule shell to slide to the left side limiting block from the tail end D2 of the guide rail so as to carry out the next process. In order to enable the extraction cup mechanism 31 to receive the coffee capsule, a capsule clamping hole 311 is formed in a corresponding position on the extraction cup mechanism, and in order to prevent the capsule extraction head from pressing down or lifting up to drive the coffee capsule to move, a capsule clamping groove 312 is further formed in the capsule clamping hole 311, and the inner wall of the capsule clamping groove is matched with the side wall of the coffee capsule.

The conveying assembly is arranged side by side with the cup throwing track 30 and arranged at the rear side of the cup throwing track, so that the conveying assembly can drive the extraction cup mechanism to move conveniently.

In the mechanism, the extraction cup mechanism is driven by the conveying belt to move to a right limit block (namely a coffee capsule receiving position) to wait, and after receiving a coffee capsule, the extraction cup mechanism moves to an extraction position (with sensor feedback). An extraction pressing plate in the capsule extraction head moves downwards to press the capsule, a needle on the extraction pressing plate punctures the capsule and injects high-temperature and high-pressure water to extract, and the extraction pressing plate moves upwards to be separated from the capsule after extraction (the conventional process of Nestle coffee). Then the extraction cup mechanism moves to a left limiting block (a recovery position) to wait for entering the next process.

Regarding the cup throwing mechanism:

referring to fig. 25-30, a reversible cup assembly 50 and a lock 51 for restraining the cup assembly 50 from being reversed when it is placed flat on the extraction cup mechanism 31 are provided on the extraction cup mechanism 31 for transporting the capsule; wherein, an elastic piece 52 is also arranged at the connection part of the throwing cup assembly 50 and the extraction cup mechanism 31, and the elastic piece 52 gives the acting force of the throwing cup assembly 50 turning to the side far away from the extraction cup mechanism 31;

a constraint structure, a locking structure and an unlocking structure are arranged on the cup throwing track 30 for the extraction cup mechanism 31 to move; the constraint structure is used for limiting the overturning of the throwing cup assembly 50 so as to enable the throwing cup assembly to be horizontally arranged above the extraction cup mechanism 31; the locking structure is used for driving the locking piece 51 to restrain the cup throwing assembly 50; the unlocking structure is used for driving the locking piece 51 to release the constraint of the cup throwing assembly 50;

after the cup throwing assembly 50 moves away from the restraining structure during the movement of the extraction cup mechanism 31 along the cup throwing track 30 to the guide rail end D2, the unlocking structure drives the locking piece 51 to release the restraint of the cup throwing assembly 50; after the cup throwing assembly 50 is driven into the restraining structure during the movement of the extracting cup mechanism 31 along the cup throwing track 30 from the end D2 to the beginning D1, the locking structure drives the locking member 51 to restrain the cup throwing assembly 50.

As shown in fig. 27 and 28, the throwing cup assembly 50 includes a throwing plate 501 and a throwing plate seat 502, wherein the throwing plate 501 is fixed on the throwing plate seat 502, a circular hole for the capsule to pass through and hold is provided at the center of the throwing plate 501, the circular hole is overlapped with the capsule clamping hole 311 at the center of the extraction cup mechanism 31 and has a uniform or slightly larger diameter, and the throwing plate seat 502 is hinged to the side of the extraction cup mechanism 31 close to the end D2 of the guide rail; the elastic element 52 is installed at the connection position of the polishing plate seat 502 and the extraction cup mechanism 31.

As shown in fig. 28 and 30, the locking member 51 is hinged to a side of the extraction cup mechanism 31 away from the end D2 of the guide rail, and a locking groove 511 is formed on a side of the locking member 51 facing the throwing plate 501, and the locking groove 511 can accommodate a side edge of the throwing plate 501 away from the throwing plate seat 502 to be clamped therein when the throwing plate 501 is flatly placed on the extraction cup mechanism 31.

Referring to fig. 26, the cup throwing rail 30 is two in number, namely, a rear cup throwing rail 303 and a front cup throwing rail 302. As will be appreciated in conjunction with fig. 29 and 30, the restraining structure is a bar rail a60 disposed below the front runner 304 of the front side casting rail 302, the upper surface of the bar rail a60 curving down to a side elevation 601 at a location proximate the distal end of the front side casting rail 302. A projection 5021 is formed on one side of the throwing plate seat 502, which faces away from the throwing plate 501. When the throwing plate seat 502 is positioned above the strip-shaped rail A60, the protrusion 5021 is limited by the upper surface of the strip-shaped rail A60 and cannot be turned over, so that the throwing plate 501 can be only flatly placed above the extraction cup mechanism 31; when the throwing plate seat 502 is driven away from the strip-shaped rail A60, the elastic piece 52 drives the throwing plate seat 502 to drive the throwing plate 501 to turn towards the side far away from the extraction cup mechanism 31, and the turning angle is limited by the contact between the protrusion 5021 and the side elevation 601 of the strip-shaped rail A60, namely when the throwing plate 501 turns to the position where the protrusion 5021 is in contact with the side elevation 601, the throwing plate 501 stops turning, so that the capsule can be easily thrown out as long as the turning speed of the throwing plate 501 is fast enough.

Referring to fig. 26, a strip rail B61 is mounted on the upper surface of the front cup throwing rail 302 outside the front sliding chute 304, and the locking structure and the unlocking structure are both arranged on the strip rail B61. In addition, the lock member 51 has an end portion 512 extending from a side thereof adjacent to the front cup throwing rail 302, and the end portion 512 rides on an upper surface of the bar-shaped rail B61.

Referring to fig. 26, the unlocking structure is a lug 612 disposed on the upper surface of the bar-shaped rail B61; the locking structure is a slope 611 formed on the upper surface of the bar-shaped rail B61, and the slope 611 is located on the side of the lug 612 far from the end of the bar-shaped rail B61.

Referring to fig. 26, a smooth stopper surface 613 for limiting the end 512 of the locking member 51 from turning over is formed on the side of the inclined surface 611 away from the end of the bar rail B61, and the smooth stopper surface 613 is parallel to the front slide groove 304 of the front casting rail 302.

Referring to fig. 26, the upper surface of the bar-shaped rail B61 between the inclined surface 611 and the lug 612 is defined as a transition plane 614, and the height of the transition plane 614 is lower than that of the smooth limiting surface 613. When the locking member 51 is in a state of releasing the constraint of the throwing cup assembly 50, the lowest point of the end 512 of the locking member 51 is higher than the transition plane 614 and lower than the smooth limiting surface 613.

Preferably, in order to facilitate the capsule to be ejected smoothly, the following constraints are applied: when the elastic element 52 is in a natural state, an included angle between the slinger 501 and the upper surface of the extraction cup mechanism 31 is not less than 90 °, wherein the included angle is equal to 90 ° in the technical scheme shown in the figure.

Preferably, a rubber ring 53 for damping the rotation of the locking member 51 is disposed between the locking member 51 and the extraction cup mechanism 31, so as to prevent the locking member 51 from being affected by vibration and other factors, and avoid the situation of mistaken unlocking.

The work flow of the cup throwing structure is as follows: after coffee is extracted, the extraction cup mechanism 31 carries the extracted capsule shell to move towards the tail end D2 of the guide rail, and in the moving process, when the throwing plate seat 502 moves away from the strip-shaped rail A60, because the upper surface of the strip-shaped rail A60 does not limit the protrusion 5021 of the throwing plate seat 502 any more, and simultaneously because the end 512 of the locking piece 51 collides with the lug 612 and turns over to release the constraint on the throwing plate 501, under the action of the elastic piece 52, the throwing plate 501 can automatically bounce (namely, rapidly turn over to the side far away from the extraction cup mechanism 31), so that the capsule is lifted and thrown out; then, the extraction cup mechanism 31 moves reversely to the guide rail start end D1, and during the moving process, when the throwing plate base 502 moves into the strip rail a60, the throwing plate base 502 is restrained by the strip rail a60, and the throwing plate base 502 carries the throwing plate 501 to reversely turn and reset (i.e., turn over to the side close to the extraction cup mechanism 31 and then flatly place on the extraction cup mechanism 31), after resetting, after the extraction cup mechanism 31 continues to move for a certain distance, the end 512 of the locking piece 51 collides with the inclined surface 611, the inclined surface 611 drives the locking piece 51 to turn over and restore the restraint on the throwing plate 501, and after that, when the extraction cup mechanism 31 continues to move to the guide rail start end D1, the end 512 of the locking piece 51 moves along the upper surface of the smooth limiting surface 613, and the smooth limiting surface 613 can limit the turning over of the end 512 and further limit the turning over of the locking piece 51, so as to prevent the locking piece 51 from releasing the.

It can be seen that, in this embodiment, after the extracted capsule is driven by the extraction cup mechanism 31 to move a certain distance to the rail end D2, the extracted capsule can be automatically bounced and thrown into a subsequent capsule recovery bucket, so that the capsule coffee machine can realize the function of automatically recovering the capsule. After recovery, the extracting cup mechanism 31 moves reversely for a certain distance, and the throwing plate 501 can automatically recover to prepare for next capsule transportation.

Referring to fig. 31 and 32, the capsule shell ejected by the cup-ejecting mechanism enters the capsule recovery box 8 through the output bend 70, wherein the output bend 70 and the input bend 201 are arranged symmetrically with respect to the capsule extraction head 5, and the two are substantially identical in shape, except that the capsule shell receiving position is completely open, so that the capsule shell can be ejected into the track smoothly. The capsule recovery box 8 is in a cuboid shape and is fixed on the side surface of the capsule storage and taking-out device 7. Therefore, the coffee machine has symmetrical and more beautiful overall appearance, and the capsule recovery box 8 is tightly attached to the capsule storage and taking-out device 7, thereby saving space.
