[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution of a Z-type elevator capable of controlling multi-point unloading:

[0021] A Z-type elevator capable of controlling multi-point unloading comprises a feeding device 1, a box body 2, a transmission assembly 3, a driving motor 4, a tray 5, a unloading hopper 6, an electric cylinder 7, a photoelectric counter 8 and a PLC control module 9; wherein the feeding device 1 is arranged above the feeding end of the box body 2, and the feeding device 1 comprises a bracket 1.1, a feeding hopper 1.2, a chute 1.3 and a vibrator 1.4; the feeding hopper 1.2 is fixed on the bracket 1.1, one end of the chute 1.3 is arranged below the feeding hopper 1.2, and the other end of the chute 1.3 is arranged above the feeding end of the box body 2, and the vibrator 1.4 is fixed on the bottom of the bracket 1.1, and the vibrating end of the vibrator 1.4 contacts the lower surface of the chute 1.3, and the formed cheese is concentratedly put into the feeding hopper 1.2, and the cheese falls on the chute 1.3. Through the continuous vibration of the vibrator 1.4, the formed cheese falls from the outlet end of the chute 1.3 into the tray 5.

[0022] The overall structure of the box body 2 is in the shape of a letter "Z". Two transmission components 3 are symmetrically arranged on the inner walls on both sides of the box body 2, wherein the transmission components 3 include: a plurality of sprocket wheels 3.1 and a transmission chain 3.2, and the transmission chain 3.2 is simultaneously engaged with the plurality of sprocket wheels 3.1 for transmission; the two sprocket wheels 3.1 opposite to each other at the bottom of the box body 2 serve as driving wheels and are connected to the driving motor 4 through a belt or a chain; the two transmission chains 3.2 are driven by the driving motor to transmit in the box body 2, and a plurality of trays 5 are rotatably arranged between the two transmission chains 3.2; but since the transmission chains 3.2 are relatively long, a plurality of brackets 11 are symmetrically fixed at the bottom of the inner walls on both sides of the top of the box body 2, and the structure of the bracket 11 is in the shape of an "E" shape. Two support plates 11.1 are horizontally arranged on the bracket 11, and the two support plates 11.1 are respectively arranged under the transmission chain 3.2. The transmission chain 3.2 is lifted up by the support plates 11.1, so as to prevent the middle part of the transmission chain 3.2 from being sunken and to avoid collision between the upper and lower trays 5 running in opposite directions; at present, three lower hoppers 6 are arranged on the lower surface of the top of the box body 2 according to production requirements, and an automatic packaging machine is placed directly under each lower hopper 6, and a barrel-shaped dust-proof plastic bag 10 is fixed to the bottom end of the lower hopper 6. The dust-proof plastic bag 10 will cover the outside of the feed hopper of the automatic packaging machine during use, so as to prevent dust and foreign matter from entering again and improve the quality of cheese during the packaging process.

[0023] In order to realize automatic unloading of the tray 5, a disc 5.1 is fixed at both ends of the tray 5, and an electric cylinder 7 is fixed on the inner wall of one side of the box body 2 and between the transmission chain 3.2 and the lower hopper 6. When the piston rod 7.1 of the electric cylinder 7 is extended, the disc 5.1 is blocked. When the piston rod 7.1 of the electric cylinder 7 is in contact with the circumferential surface of the disc 5.1, the tray 5 can be turned over, and the formed cheese in the tray 5 is poured into the lower hopper 6 and finally falls into the feed hopper of the automatic packaging machine, thereby realizing the automatic unloading action of the tray 5.

[0024] Since there are currently six pallets 5 passing between two adjacent electric cylinders 7, in order to enable three unloading hoppers 6 to unload materials simultaneously, a photoelectric counter 8 is fixedly provided under any one of the electric cylinders 7, and a PLC control module 9 is provided on the outer surface of the box body 2. The PLC control module 9 is electrically connected to the drive motor 4, the electric cylinder 7 and the photoelectric counter 8 respectively.

[0025] The photoelectric counter 8 detects the number of passing trays 5 through photoelectric elements, and sends a pulse signal generated by the counting result to the PLC control module 9 for processing. The PLC control module 9 receives the pulse signal, and the built-in counter function counts the pulse signal. The PLC control module 9 controls the extension or retraction time of the piston rods 7.1 of the three electric cylinders 7 according to the count of the number of passing trays 5, so that the three unloading hoppers 6 can unload materials at the same time, reducing the work of manual loading, reducing personnel costs, and ensuring the original unloading efficiency.

[0026] Working principle: In this embodiment, it is known that there are three unloading hoppers 6 and the number of trays 5 passing between two adjacent electric cylinders 7 is six; therefore, when all the trays 5 between two adjacent electric cylinders 7 are turned over, the number of trays 5 passing through the photoelectric counter 8 is exactly six. At this time, when the last unloading hopper 6 along the unloading direction wants to continue unloading, there will be an idle period when twelve trays 5 are not fully loaded with cheese. Therefore, the three electric cylinders 7 must be retracted at this time, otherwise the cheese in the tray 5 will fall into the first unloading hopper 6 along the unloading direction, and no cheese will fall into the two subsequent unloading hoppers 6. Therefore, in this embodiment, The time of the idle period is when the number of trays 5 passing through the photoelectric counter 8 is twelve; therefore, when all the trays 5 are fully loaded with cheese, as the drive motor 4 is started, the PLC control module 9 will control the piston rods 7.1 of the three electric cylinders 7 to extend, and the extension time is when the number of trays 5 passing through the photoelectric counter 8 is six; after six trays 5 have passed, the photoelectric counter 8 will count again, and at this time the PLC control module 9 will control the piston rods 7.1 of the three electric cylinders 7 to retract, and the retraction time is when the number of trays 5 passing through the photoelectric counter 8 is twelve. After twelve trays 5 have passed, the last unloading hopper 6 along the unloading direction can continue to unload.

[0027] If the number of lower hoppers 6 in this embodiment is N, the number of trays 5 passing between two adjacent electric cylinders 7 is M; it is not difficult to deduce that the extension time is the number of trays 5 passing through the photoelectric counter 8 is N; the retraction time is the number of trays 5 passing through the photoelectric counter 8 is N (M-1).

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
