The processing device processes the raw materials to obtain semi-finished materials (semi-finished materials refer to semi-finished materials after certain processing and treatment), and then places the semi-finished materials on the pallet again for output. However, currently, only one pallet can be set in the feeding and receiving device. After the pallet is full of semi-finished materials, it is taken out by an operator, and then a pallet full of raw materials is replaced to supply the raw materials again. This process is repeated, resulting in a great waste of labor costs.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

Moreover, the first feature being "above", "above the top", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0047] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0048] In this embodiment, a CNC machining device is proposed, which includes a machining device and a feeding and discharging device. Among them, the machining device is used to machine raw materials. The machining device is an existing machining structure and can be selected according to the raw material model and different machining requirements, which will not be elaborated here. The feeding and discharging device is used to supply the raw materials to be machined to the machining device and receive the finished products machined by the machining device. The feeding and discharging device can reduce the frequency of operators supplying raw materials and collecting finished products, so as to reduce the labor cost.

[0049] Specifically, please refer to Figures 1 to 5 , the feeding and discharging device includes a carrier 1, a plurality of trays 2, a feeding mechanism 3, a transfer mechanism 4 and a discharging mechanism 5. The plurality of trays 2 are all used to carry raw materials and / or finished products; the feeding mechanism 3 is arranged on the carrier 1, and the plurality of trays 2 are stacked in the height direction on the feeding mechanism 3; the transfer mechanism 4 is arranged between the feeding mechanism 3 and the machining device. The transfer mechanism 4 is used to transfer the raw materials on the top tray 2 on the feeding mechanism 3 to the machining device and transfer the finished products machined by the machining device back to the top tray 2; the discharging mechanism 5 is arranged on the carrier 1 and is arranged opposite to the feeding mechanism 3. The discharging mechanism 5 is used to layer by layer receive the trays 2 carrying the finished products transferred by the feeding mechanism 3.

[0050] It can be understood that according to the needs, one or more raw materials are placed on the tray 2, and the plurality of trays 2 are arranged on the feeding mechanism 3 in the height direction. Then, the feeding mechanism 3 and the discharging mechanism 5 are placed on the carrier 1. The transfer mechanism 4 can transfer the raw materials on the tray 2 to the machining device, and the machining device processes them. After processing, under the action of the transfer mechanism 4, the finished products can be put back on the tray 2. After all the raw materials on one layer of the tray 2 are processed into finished products, the tray 2 can be transferred by the feeding mechanism 3 to the discharging mechanism 5. When all the raw materials on the feeding mechanism 3 are processed into finished products layer by layer, all the trays 2 on the feeding mechanism 3 can be received by the discharging mechanism 5. By means of the feeding mechanism 3 and the picking mechanism, the number of feeding and discharging trays per operation of the operator can be increased, thereby reducing the labor cost.

[0051] Preferably, the specific structures of the feeding mechanism 3 and the discharging mechanism 5 are the same. Here, the feeding mechanism 3 is taken as an example for elaboration. The feeding mechanism 3 includes a silo 31. The silo 31 is provided with a plurality of accommodating parts 311 adapted to the trays 2 in the height direction, and openings 3111 through which the trays pass are provided on the same side of the plurality of accommodating parts 311. The openings 3111 face the discharging mechanism 5. It can be understood that when the operator places the trays 2, the different trays 2 are inserted into the corresponding accommodating parts 311 in the silo 31 through the openings 3111, so that the trays 2 in the silo 31 can be arranged in the height direction, which is convenient for increasing the number of feeding and discharging trays per operation of the operator.

[0052] It should be noted that after the feeding mechanism 3 and the material receiving mechanism 5 are placed on the stage 1 at the same time, the openings 3111 on the feeding mechanism 3 are opposite to the openings 3111 on the material receiving mechanism 5. After the clinker is placed on the tray 2 by the transfer mechanism 4, it can be moved out from the opening 3111 on the feeding mechanism 3 and moved into the material receiving mechanism 5 through the opening 3111 on the material receiving mechanism 5. With this arrangement, the stability of the tray 2 during movement can be improved.

[0053] In this embodiment, the silo 31 includes a bottom plate 313 and at least two side plates 314. The at least two side plates 314 are arranged vertically on the top of the bottom plate 313, and receiving portions 311 are provided on the opposite sides of adjacent two side plates 314. It can be understood that when placing the tray 2, the two sides of the tray 2 are respectively placed in the receiving portions 311 on both sides. The receiving portions 311 on both sides can provide guidance and limit for the movement of the tray 2, so as to avoid deviation of the tray 2 during movement, ensure the accuracy when the transfer mechanism 4 transfers raw materials or clinker, and also ensure the stability of the tray 2 during the process of moving from the feeding mechanism 3 to the material receiving mechanism 5.

[0054] Among them, the receiving portion 311 is preferably a receiving groove, and the receiving grooves on both sides are arranged oppositely. The two sides of the tray 2 extend into the receiving grooves. Of course, in some other feasible embodiments, the receiving portion 311 can be a bearing plate for lapping the tray 2.

[0055] In addition, the transfer mechanism 4 is also used to push the tray 2 to translate, so that the tray is translated from the feeding mechanism 3 to the material receiving mechanism 5. It can be understood that after the transfer mechanism 4 places the clinker on the corresponding tray 2, the feeding mechanism 3 can move one side of the silo 31 and be at the same height as the tray 2. Since the two side plates 314 are spaced apart, it can provide a space for pushing the tray 2 to translate, so that the transfer mechanism 4 can push the tray 2 to translate to the material receiving mechanism 5.

[0056] Exemplarily, the transfer mechanism 4 includes a moving module and a gripper. The gripper is arranged on the moving end of the moving module. The moving module is used to drive the gripper to reciprocate between the feeding mechanism 3 and the material receiving mechanism 5, and the height of the gripper is adjustable. The gripper is used to grab raw materials or clinker, and drive the tray 2 to translate. With this arrangement, the driving structure for driving different trays 2 to move can be saved, so as to save production costs and the space occupancy rate of the entire feeding and receiving device.

[0057] In this embodiment, a plurality of limiting portions 312 are provided on the silo 31, and the plurality of limiting portions 312 are provided in one-to-one correspondence with the plurality of accommodating portions 311, and are located on the side away from the corresponding opening 3111; the feeding mechanism 3 also includes a blocking member 35 and a driving member 36, the blocking member 35 is movably provided at the opening 3111, and has a blocking state of blocking the opening 3111 and an opening state of opening the opening 3111; the driving member 36 is used to drive the blocking member 35 to switch between the blocking state and the opening state. It is understandable that when the operator places the tray 2 into the silo 31, the operator controls the blocking member 35 to be in an open state, places the tray 2 in the accommodating portion 311, and pushes the tray 2 to continue moving until the tray 2 abuts against the limiting portion 312, which proves that the tray 2 has moved into position, and then controls the blocking member 35 to be in a blocking state, and the tray 2 can be clamped under the action of the blocking member 35 and the limiting portion 312, so that the position accuracy of the tray 2 can be ensured, thereby preventing the tray 2 from being offset due to the force applied by the transport unit to the tray 2 during the process of the transport unit clamping raw materials from the tray 2 or placing clinker on the tray 2. In addition, the limiting portion 312 is a stopper, which is arranged at the end of the travel of the tray 2.

[0058] It should be noted that, when the transfer unit pushes the pallet 2 to move horizontally to the material receiving mechanism 5, the pallet 2 can abut against the limiting portion 312 of the material receiving mechanism 5, thereby proving that the pallet 2 has moved horizontally into place, avoiding excessive travel of the pallet 2, and improving safety performance.

[0059] Preferably, the blocking member 35 is in the shape of an elongated strip, and a plurality of apertures 351 adapted to the openings 3111 are arranged at intervals on the blocking member 35; the blocking member 35 is slidably arranged on the silo 31 in the vertical direction so that the openings 3111 and the apertures 351 are directly opposite or staggered. It is understandable that the elongated blocking member 35 can open or block all the openings 3111 at the same time through the driving member 36. In the process of placing the trays 2, the blocking member 35 can open all the openings 3111 at the same time, so as to place a plurality of trays 2 inside the silo 31 and then take the trays 2 out of the silo 31.

[0060] In addition, a limiting rod 37 is provided on the silo 31, and the blocking member 35 is provided with an oblong hole 352 for the limiting rod 37 to pass through. The length direction of the oblong hole 352 is arranged vertically. When the limiting rod 37 abuts against the top end of the oblong hole 352, the opening 3111 and the orifice 351 are staggered. When the limiting rod 37 abuts against the bottom end of the oblong hole 352, the opening 3111 and the orifice 351 are arranged opposite to each other. A notch 11 is provided on the carrier 1 opposite to the blocking member 35. The driving member 36 is arranged below the carrier 1, and the driving end of the driving member 36 can pass through the notch 11 to push against the blocking member 35 to move upward. It can be understood that when the silo 31 is placed on the carrier 1, the blocking member 35 can naturally hang down under its own gravity. At this time, the limiting rod 37 abuts against the top end of the oblong hole 352, and the opening 3111 and the orifice 351 can be staggered. When the tray 2 needs to be moved from the feeding mechanism 3 to the receiving mechanism 5, the driving member 36 is used to push against the blocking member 35 to move upward, so that the limiting rod 37 abuts against the bottom end of the oblong hole 352, and the opening 3111 and the orifice 351 can be arranged opposite to each other. After the tray 2 is moved from the feeding mechanism 3 to the receiving mechanism 5, the driving member 36 resets, and the blocking member 35 naturally hangs down again under its own gravity. Among them, the driving member 36 is preferably a linear driving mechanism in the prior art, such as a cylinder, etc., which will not be elaborated here.

[0061] In practical applications, two blocking members 35 are provided and are respectively slidably arranged on the two side plates 314. Each of the corresponding two blocking members 35 corresponds to a driving member 36. After the feeding mechanism 3 and the receiving mechanism 5 are placed on the carrier 1, the blocking members 35 on the feeding mechanism 3 and the receiving mechanism 5 are arranged opposite to each other and abut against each other relatively to ensure the stability of the tray 2 during the transfer process. In addition, the blocking members 35 on the feeding mechanism 3 and the receiving mechanism 5 can be driven by the same driving member 36 or can be respectively driven by the corresponding driving members 36.

[0062] Of course, in some other feasible embodiments, the driving member 36 is arranged on the silo 31 and is directly connected to the blocking member 35. Under the action of the driving member 36, the blocking member 35 is directly switched between the blocking state and the open state.

[0063] In addition, when the blocking member 35 is in the blocking state, the bottom end of the blocking member 35 extends to the outside of the silo 31. When the silo 31 is placed on a platform or the ground, the blocking member 35 will move upward, so that the blocking member 35 can be switched from the blocking state to the open state. Such a setting is convenient for the operator to place the tray 2 on the silo 31 or take out the tray 2 from the silo 31 without the need for an additional driving member 36 to drive, so as to improve the convenience.

[0064] In this embodiment, the feeding and discharging device further includes a plurality of limiting blocks 6. The plurality of limiting blocks 6 are arranged on the carrier 1 and are arranged around the circumferences of the feeding mechanism 3 and the discharging mechanism 5 to limit the circumferences of the feeding mechanism 3 and the discharging mechanism 5. It can be understood that under the action of the limiting blocks 6, the position accuracy of the feeding mechanism 3 and the discharging mechanism 5 can be guaranteed, so that the accuracy of the transfer part during the transfer of raw materials or clinker can be further guaranteed.

[0065] In practical applications, the limiting blocks 6 can limit the positions of the feeding mechanism 3 and the discharging mechanism 5 respectively, or can limit the positions of the feeding mechanism 3 and the discharging mechanism 5 simultaneously, which will not be elaborated here.

[0066] Furthermore, the feeding and discharging device further includes a locking mechanism 7. The locking mechanism 7 is arranged on the carrier 1. The locking mechanism 7 is used to lock the feeding mechanism 3 and the discharging mechanism 5 on the carrier 1. It can be understood that after the feeding mechanism 3 and the discharging mechanism 5 are placed on the carrier 1, under the action of the locking mechanism 7, the feeding mechanism 3 and the discharging mechanism 5 can be locked, so that the feeding mechanism 3 and the discharging mechanism 5 can be prevented from moving during the transfer of raw materials or the transfer of the tray 2. After the CNC machining is completed, the locking mechanism 7 can unlock the feeding mechanism 3 and the discharging mechanism 5 to facilitate the operator to take out the feeding mechanism 3 and the discharging mechanism 5 from the carrier 1.

[0067] Specifically, the locking mechanism 7 includes a rotating member 71 and a locking block 72. The locking block 72 is strip-shaped and is arranged at the driving end of the rotating member 71. The rotating member 71 can drive the locking block 72 to rotate around the driving end of the rotating member 71; a locking hole is formed in the bottom plate 313, and the locking hole is adapted to the locking block 72. When the operator places the silo 31, the silo 31 is placed on the carrier 1, and the locking block 72 is passed through the locking hole, and then the rotating member 71 is controlled to drive the locking block 72 to rotate to complete the locking of the silo 31.

[0068] In this embodiment, the feeding and discharging device further includes a cleaning mechanism 8 and a foolproof detection mechanism 9. The cleaning mechanism 8 and the foolproof detection mechanism 9 are both arranged on the transfer path of the transfer mechanism 4. The cleaning mechanism 8 is used to clean the dirt on the raw materials or clinker. The cleaning mechanism 8 is preferably an air outlet cleaning structure in the prior art, which will not be elaborated here. The foolproof detection mechanism 9 can detect the raw materials or clinker to ensure the processing quality of the processing device.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
