Referring to fig. 1-3, a cup dropping device for an automatic catering device comprises a cup cylinder 701 for storing a standby beverage cup, a cup dropping driving mechanism 702 arranged below the cup cylinder 701, a fixed frame arranged below the cup dropping driving mechanism 702, and a cup holder 703 arranged between the fixed frame and the cup dropping driving mechanism 702.

Preferably, the cup drop drive mechanism 702 includes an upper cover 721, a ring gear 722, a gear set 723, a lower cover 724, and a motor 725.

The cartridge 701 is used for storing a beverage cup to be used, such as a disposable paper cup, a disposable plastic cup and the like, and the cartridge 701 may be provided in a plurality, such as 2-5, and may store the same or different types of cups, respectively.

The cup drop drive mechanism mounting bracket 704 includes a bottom plate 741, a back plate 742, a top plate 743, a front stiffener 744, and a rear stiffener 745. The top plate 743 is provided with a circular hole for mounting the cup cylinder 701, and a cup falling driving mechanism 702 is mounted at a position corresponding to the circular hole below the top plate 743. The back plate 742 has a slot for receiving a motor of the cup drive mechanism 702. The back plate 742 is covered at the rear with a dust cover 705. The bottom plate 741 is provided with a mounting groove for mounting the cup holder base 706. The cup holder 703 is inserted into the mounting hole of the cup holder base 706 by the connecting rod at the lower portion thereof, thereby achieving fixation and enabling easy replacement. The cup holder 703 and the cup holder base 706 are preferably made of a plastic material. The cup holder 703 has an internal cavity adapted to receive a beverage cup and has a notch in its side to facilitate robotic grasping or suction of the catering device. The cup cylinder 701, the cup falling driving mechanism 702 and the cup holder 703 are in one-to-one correspondence from top to bottom.

Referring to fig. 4, the gear set 703 includes a plurality of sets of gear pairs, at least three, preferably 5, equally spaced sets. Each gear pair comprises a first gear 731 and a second gear 732, and a spiral beverage cup buckle is arranged at the lower part of the second gear. As shown in fig. 4, the spiral beverage cup clasp has a spiral slope.

The gear ring 722 and the gear set 723 are arranged in a cavity formed by the upper cover 721 and the lower cover 724, and the gear ring 722 is sleeved on the outer ring of the gear set 703. The rotation shaft of the motor drives the gear ring 722 to rotate, the gear ring drives the first gear of each gear pair of the gear set to rotate, the first gear drives the second gear to rotate, and the second gear drives the spiral beverage cup buckle to rotate.

The working process of the cup dropping device for the automatic catering equipment is as follows: reserve beverage cup (just putting) has been deposited in advance in the glass section of thick bamboo, the beverage cup rim of a cup is established on cup actuating mechanism along the card, when the cup falls to needs, starter motor, the pivot of motor drives ring gear 722 and rotates, the ring gear drives the first gear rotation of every gear pair of gear train, first gear drives the second gear rotation, the second gear drives spiral beverage cup and detains rotatoryly, beverage cup descends under the effect that spiral beverage cup detained this moment, until dropping, and fall into in the saucer, snatch or absorb with the robot that supplies automatic food and beverage device. The sensor is arranged in the cup barrel, and when the cup is not filled in the cup barrel, an alarm can be given out to remind an operator to feed materials.

Further preferably, the sensor may be a photoelectric sensor, a pressure sensor, or the like which can sense whether or not an article is present in the cartridge.

The cup falling mechanism is suitable for cups with proper calibers and without cup covers, and can be stacked, such as common disposable cups. The maximum diameter d1 of the cup edge is larger than the tangential circular diameter d2 formed by 5 spiral beverage cup buttons, so that the cup can not fall off in the non-operation state of the machine. The bottom cup has a rim below which contacts the upper surface of the spiral slope of the spiral beverage cup holder (not necessarily where the spiral surface is highest). After the machine is started, the spiral beverage cup buckle rotates, the contact position of the cup edge and the spiral beverage cup buckle moves downwards along the spiral surface, and finally the cup edge is separated from the spiral surface and falls down to the cup stand below. When the lowest cup falls down, the penultimate cup is in the difference relationship of the thickness of the cup edge and the height difference between the upper part and the lower part of the two spiral surfaces of the spiral cup buckle, namely the height of the cup edge of the screw pitch is smaller than that of the two cups, namely the screw pitch is less than the sum of the heights of the cup edges of the two cups (so that the two cup edges can not be clamped in the same screw pitch, and the number of turns of the screw is at least close to or more than 1 turn, so that the uppermost spiral slope surface is screwed into the position below the cup edge of the penultimate cup before the lowest cup falls down along the lowermost spiral slope surface, so that the penultimate cup is clamped, and when the uppermost spiral slope surface is screwed into the position below the cup edge of the penultimate cup, because the, the penultimate cup cannot fall down, so that only one cup can fall down at a time.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
