In order to solve the technical problem that the work efficiency is low in a mode of unstacking and conveying one by one, as shown in fig. 1, embodiment 1 provides an unstacking and conveying production line 01, which comprises a tray 1 (see fig. 2), a lower layer integral input line 2, an upper layer tray output line 3, a material box output line 4, a lifting mechanism 5 and a horizontal pushing mechanism 6; as shown in fig. 2, the tray 1 is a multi-layer stacked structure; a plurality of material boxes 10 arranged in a matrix are arranged on the tray 1; the tray 1 is used for loading the magazine 10. In fig. 2, the tray 1 has five layers, and each layer is provided with two rows of six material boxes 10 (the material boxes 10 are used for containing goods). The type of the goods includes, but is not limited to, raw meat. The upper layer tray output line 3 is positioned right above the lower layer integral input line 2; the lifting mechanism 5 comprises a lifting mechanism inner roller way 50; the inner roller way 50 of the lifting mechanism can be butted with the lower layer integral input line 2 or the upper layer tray output line 3; the height of the material box output line 4 is positioned between the lower layer integral input line 2 and the upper layer tray output line 3; the horizontal pushing mechanism 6 is used for unstacking the material boxes 10 on the tray 1 from the lifting mechanism 5 to the material box output line 4 layer by layer.
The working method for unstacking and conveying by adopting the unstacking and conveying production line 01 provided by the embodiment 1 comprises the following steps as shown in fig. 3:
s1: the tray 1 loaded with a plurality of material boxes 10 is conveyed to an inner roller way 50 of the lifting mechanism along a lower layer integral input line 2;
s2: the lifting mechanism 5 lifts the tray 1 and all the cartridges 10 on the tray along with the inner roller way 50 of the lifting mechanism until the cartridges 10 with the lowest height on the tray 1 are flush with the output lines 4 of the cartridges, and the lifting mechanism 5 stops lifting action and keeps the height of the tray 1 unchanged;
s3: the horizontal pushing mechanism 6 acts on the layer of material box 10, so that the layer of material box 10 is unstacked to the material box output line 4 from the lifting mechanism 5;
s4: step S2 to step S3 are the unstacking process of one layer of magazine 10, and step S2 to step S3 are repeated until the unstacking of all the magazines 10 is completed;
s5: the lifting mechanism 5 lifts the empty tray 10 along with the inner roller way 50 of the lifting mechanism until the height of the tray 1 is flush with that of the tray output line 3, and the lifting mechanism 5 stops lifting action and keeps the height of the tray 1 unchanged;
s6: the lifting mechanism inner roller way 50 drives the tray 10 to be conveyed to the tray output line 3 by the lifting mechanism 5.
Wherein, the step S2 to the step S3 are the unstacking and conveying process of the material boxes 10 on the tray 1; steps S5 to S6 are the transfer conveyance process of the tray 1.
After step S6, the method further includes:
s7: when it is detected that the tray 1 has reached the tray output line 3, the elevating mechanism 5 is lowered until the elevating mechanism inner roller table 50 is flush with the height of the lower layer integrated input line 2.
The steps S1 to S7 can be performed in a loop to achieve the purpose of continuous unstacking and conveying.
The unstacking and conveying production line 01 provided by the embodiment 1 is based on the multilayer structure characteristics of the orderly layout of the tray 1, and the relative positions of the tray 1 (see fig. 2), the lower layer integral input line 2, the upper layer tray output line 3, the magazine output line 4, the lifting mechanism 5 and the horizontal pushing mechanism 6 are subtly arranged, so that the purpose of unstacking and conveying the magazine 10 and goods therein layer by layer is realized. Specifically, the lifting mechanism 5 adjusts the layer of the material boxes 10 to be unstacked to the height flush with the horizontal pushing mechanism 6, and at the height, all the material boxes 10 on the layer to be unstacked can be quickly and synchronously pushed into the material box output line 4 through the pushing action of the horizontal pushing mechanism 6. The magazine output line 4 then carries the magazines 10 thereon to further processing or transport. After all the material boxes 10 are unstacked, the tray 1 is continuously lifted upwards through the lifting mechanism 10, so that the inner roller way 50 of the lifting mechanism can be quickly butted with the output line 3 of the upper tray; the tray 10 is driven by the inner roller way 50 of the lifting mechanism to be conveyed to the tray output line 3 by the lifting mechanism 5, the transfer conveying of the empty tray 1 is completed, and the tray output line 3 can be used as a part of a return line of the empty tray 1, so that conditions are created for the automatic return of the empty tray 1. The unstacking conveying production line 01 provided by the embodiment 1 realizes the layer-by-layer unstacking conveying of the material boxes 10 and the automatic backflow conveying of the empty trays 1, and compared with the traditional mode of one-by-one unstacking conveying, the automatic unstacking conveying production line does not need to accurately position and split the single material box 10, reduces the positioning precision requirement and the positioning frequency, simplifies the step of unstacking conveying, and greatly improves the working efficiency of unstacking conveying and the reliability of mechanical operation.
In order to quickly and accurately machine-identify the goods in the material box so as to facilitate subsequent transportation or packaging treatment, further, an RFID reader-writer is arranged on the lifting mechanism 5; an RFID electronic tag is arranged on the tray 1, and the RFID electronic tag is written with the goods information of the material box 10 on the tray 1; the RFID reader/writer is used for reading the RFID electronic tag on the tray 1. By providing the RFID tag at a designated position of the tray 1, accurate and efficient identification by the RFID reader can be ensured during dynamic conveyance. Through the cooperation of the RFID electronic tag written with the goods information and the RFID reader-writer, the goods information reaching the lifting mechanism 5 can be quickly acquired. The RFID reader-writer is easy to operate and control, simple and practical and particularly suitable for automatic control, and the identification work does not need manual intervention and contact; the RFID reader-writer is convenient and fast to read and high in safety. The RFID reader-writer can better guarantee the accuracy and the high efficiency of the goods information acquisition. The obtained goods information can be uploaded to an upper computer to realize real-time positioning and tracking of goods in the material box 10 and prepare for subsequent packaging of the material box 10: for example, the goods information corresponding to the material boxes 10 is sequentially sent to the printer of the packaging machine according to the arrangement sequence of the material boxes 10, so that the printing preparation work is done in advance, the goods information and the material boxes 10 can strictly correspond one to one, and the automatic packaging and printing are favorably realized.
In order to improve the operation reliability of the unstacking and conveying production line, further, a first proximity sensor is arranged at the output end of the lower-layer integral input line 2; a second proximity sensor is arranged on the inner roller way 50 of the lifting mechanism; the input end of the upper layer tray output line 3 is provided with a third proximity sensor; the first proximity sensor, the second proximity sensor, and the third proximity sensor are used to detect whether the tray 1 reaches a specified position.
Only when the proximity sensor detects that the tray 1 reaches the designated position, the relevant device is triggered to send out corresponding action. Specifically, the method comprises the following steps:
(1) when first proximity sensor detects tray 1 and reachs the output of the whole input line 2 of lower floor, first proximity sensor will detect the signal transmission of tray 1 and carry the upper computer system of production line 01 to unstacking, and upper computer system sends the instruction to elevating system 5, and elevating system 5 confirms that elevating system 5's height and the whole input line 2 of lower floor's height parallel and level after no tray 1 on the roll table 50 in the elevating system, can satisfy the butt joint condition. Then, the upper computer system sends an instruction to the output end of the lower layer integral input line 2, and the output end of the lower layer integral input line 2 drives the tray 1 to go to the lifting mechanism inner roller 50. The upper computer system sends an instruction to the lifting mechanism 5, and the lifting mechanism 5 confirms that the tray 1 reaches the designated position on the inner roller way 50 of the lifting mechanism. The upper computer system sends an instruction to the output end of the lower layer integral input line 2, and the output end of the lower layer integral input line 2 stops acting.
(2) When the second proximity sensor detects that the tray 1 reaches the inner roller way 50 of the lifting mechanism, the second proximity sensor sends a signal for detecting the tray 1 to an upper computer system of the unstacking conveying production line 01, the upper computer system sends an instruction to the horizontal pushing mechanism 6, and the horizontal pushing mechanism 6 confirms that the tray is ready (the horizontal pushing mechanism 6 is at an initial position and cannot interfere with the lifting mechanism 5); the upper computer system sends an instruction to the lifting mechanism 5, the lifting mechanism 5 lifts the tray 1 and all the cartridges 10 on the tray along with the inner roller way 50 of the lifting mechanism until the cartridges 10 with the lowest height on the tray 1 are flush with the height of the cartridge output line 4, and the lifting mechanism 5 stops lifting action and keeps the height of the tray 1 unchanged.
(3) When the third proximity sensor detects that the tray 1 reaches the input end of the upper-layer tray output line 3, the third proximity sensor sends a signal for detecting the tray 1 to an upper computer system of the unstacking and conveying production line 01, the upper computer system sends an instruction to the upper-layer tray output line 3, and the upper-layer tray output line 3 conveys the tray 1 to the output direction of the upper-layer tray output line 3; meanwhile, the upper computer system sends an instruction to the lifting mechanism 5, and after the lifting mechanism 5 has no tray 1 on the inner roller way 50 of the lifting mechanism, the lifting mechanism 5 descends until the height of the inner roller way 50 of the lifting mechanism is flush with that of the lower layer integral input line 2.
The real-time position of the tray 1 is tracked at a fixed point through the first proximity sensor, the second proximity sensor and the third proximity sensor, and in the process of unstacking and conveying, the follow-up action can be started after the execution of the related action is in place, so that the operation reliability of the unstacking and conveying production line 01 is greatly improved.
Because the subsequent processes need to perform modified atmosphere packaging on the material boxes, the existing automatic modified atmosphere packaging machine can only package a certain number of material boxes (equal to the number of synchronous packaging positions) synchronously, and the pressure conditions required by the packaging of the automatic modified atmosphere packaging machine cannot be ensured when the number of the material boxes is less than or more than the number of the material boxes, so that the automatic modified atmosphere packaging machine cannot work normally. In order to detect the number of the material boxes unstacked to the output line of the material boxes in each layer so as to independently process the material boxes with less than full number in advance, further, as shown in fig. 4, a certain number of photoelectric sensors 40 are arranged at the input end of the output line 4 of the material boxes; the photoelectric sensor 40 is used to detect whether the cartridge 10 reaches a specified position. The number of the photoelectric sensors 40 is equal to the number of the synchronous packaging positions of each row of the material boxes 10 when the tray 1 is fully loaded, and the photoelectric sensors 40 are arranged in one-to-one correspondence with the material boxes 10. Can detect the position of the magazine of unstacking to the magazine output line through photoelectric sensor 40, through carrying out assay count with photoelectric sensor 40 testing result, can obtain the magazine 10 quantity of each layer of unstacking to magazine output line 4 to in advance carry out manual handling alone with the magazine 10 of unsatisfied quantity. Thereby preventing the batch packs 10 from reaching the automatic modified atmosphere packaging machine and causing operational failure of the automatic modified atmosphere packaging machine.
In order to classify different material boxes, reduce faults and improve the overall efficiency of the unstacking and conveying production line, the unstacking and conveying production line 01 further comprises an automatic material box packaging conveying line and a manual material box packaging conveying line; the magazine output line 4 is selectively routed to either a magazine automatic packing line or a magazine manual packing line. When the photoelectric sensor 40 detects that the number of the material boxes is equal to that of the synchronous packaging positions, the material box output line 4 rotates forwards to drive the material box output line 4 to go to the automatic material box packaging conveying line; when the photoelectric sensor 40 detects that the number of the material boxes is less than that of the synchronous packaging positions, the material box output line 4 is reversed to drive the material box output line 4 to go to the material box manual packaging conveying line.
The batch box 10 is to complete synchronous automatic packaging and labeling on an automatic modified atmosphere packaging machine on an automatic packaging and conveying line of the material box, wherein labeling information is transmitted to goods information of an upper computer from the lifting mechanism 5.
Or the batch material boxes 10 are manually packaged and labeled one by one on a manual packaging machine on a manual packaging conveying line of the material boxes, wherein labeling information is transmitted to the goods information of the upper computer from the lifting mechanism 5.
The unstacking conveying production line 01 provided by the preferred embodiment can classify different material boxes, so that faults are reduced, and the overall efficiency of the unstacking conveying production line 01 is improved.
In order to timely process the material boxes entering the material box manual packaging conveying line, a reminding device and a reset button are further arranged on the material box output line 4; the reminding device is used for sending manual processing reminding information; the reset button is used for marking the end of manual processing and restarting the unstacking conveying production line 01. After the upper computer system of the unstacking conveying production line 01 acquires the quantity information of the material boxes detected by the photoelectric sensor 40, the upper computer system sends an instruction to the reminding device on the material box output line 4, and the reminding device sends an audible and visual alarm signal to an operator to remind the operator of manual treatment in time. Preferably, the upper computer system can also send reminding information to the mobile communication equipment of the operator through the remote communication device. After the operator has manually processed the batch cassette 10, the unstacking conveyor line 01 can be restarted by pressing a reset button. The unstacking conveying production line 01 is switched to an automatic mode after being restarted. The unstacking and conveying production line 01 executes the steps S1 to S7 according to the control program of the upper computer system.
In order to provide a lifting mechanism suitable for the unstacking conveying production line, specifically, as shown in fig. 5, the lifting mechanism 5 further comprises a lifting power assembly 51 and a lifting sliding table module 52; the lifting power assembly 51 is used for driving the lifting sliding table module 52 to lift on a vertical plane; the inner roller way 50 of the lifting mechanism is fixed with the movable end of the lifting sliding table module 52 and is used for placing the tray 1. The lifting mechanism combined by the lifting power assembly 51, the lifting sliding table module 52 and the inner roller way 50 of the lifting mechanism has simple structure and stable and reliable lifting action, and can realize stable lifting action and accurate height positioning of the tray 1, thereby being particularly suitable for unstacking and conveying production lines 01.

The lifting power provided by the first servo motor 510 can be in linkage control with other equipment (such as the horizontal pushing mechanism 6 and the material box output line 4) through the electric control device, a good foundation is laid for automatic control of the unstacking and conveying production line 01, the cost is relatively low, and the technical maturity is high.
In order to provide a lifting sliding table module with simple structure, smooth operation and reliable action, further, as shown in fig. 5 and fig. 6, the lifting sliding table module 52 comprises a parallel lifting sliding rail 520, a lifting slider and a lifting ball screw; the extension direction of the parallel lifting slide rail 520 is arranged along the vertical direction; the parallel lifting slide rail 520 is fixed on the lifter mounting rack 53; the lifting ball screw is in transmission connection with an output shaft of the first servo motor 510; the lifting slide block is driven by a lifting ball screw and can be arranged on the parallel lifting slide rail 520 in a sliding manner; the lifting mechanism inner roller 50 is fixed on the lifting slide block. The working principle of the lifting sliding table module 52 is as follows: the first servo motor 510 provides power, and drives the screw of the lifting ball screw to rotate along with the rotation of the output shaft of the first servo motor 510. Because the lifting slide block is slidably disposed on the parallel lifting slide rail 520, the middle portion of the lifting slide block is fixedly connected to the nut of the lifting ball screw, and the nut of the lifting ball screw drives the lifting slide block to linearly move on the screw of the lifting ball screw along the parallel lifting slide rail 520. The lifting sliding table module 52 has the advantages of simple structure, small occupied size, high running stability and reliable action, can realize quick positioning, and is convenient for realizing full-automatic lifting control.
In order to facilitate reliable installation and fixation of the roller way in the lifting mechanism, further, as shown in fig. 5 and 6, the lifting mechanism 5 further includes a rectangular parallelepiped fixing frame 54; the cuboid fixed frame 54 corresponds to the lifting mechanism inner roller way 50; the cuboid fixed frame 54 is used for bearing the inner roller way 50 of the lifting mechanism; the elevating mechanism inner roller 50 is fixed to the elevating slider by a rectangular parallelepiped fixing frame 54. The rectangular fixing frame 54 is convenient for reliable installation and fixation of the roller way 50 in the lifting mechanism; secondly, the cuboid fixed frame 54 can play a certain limiting role in the horizontal direction and the vertical direction, so that the phenomenon that the tray 1 is separated from the inner roller way 50 of the lifting mechanism due to the inertia effect in the process of acting along with the lifting mechanism can be reduced, and the safety of the goods in the lifting process is improved.
In order to provide a horizontal pushing mechanism suitable for conveying production line breaks a jam, further, as shown in fig. 5, horizontal pushing mechanism 6 includes pushing away material mounting bracket 60, ejector beam 61, pushing away material power component 62 and horizontal slip table module 63; the material pushing power assembly 62 is used for driving the horizontal sliding table module 63 to perform translation motion on the horizontal plane; the material pushing rod 61 is fixed with the movable end of the horizontal sliding table module 63; the pushing power assembly 62 is movably fixed on the pushing mounting bracket 60; the fixed end of the horizontal sliding table module 63 is fixed on the material pushing mounting frame 60. The working principle of the horizontal pushing mechanism 6 is as follows: the material pushing power assembly 62 provides translation power for the horizontal sliding table module 63, the horizontal sliding table module 63 drives the material pushing rod 61 to move horizontally and linearly, the material pushing rod 61 reaches the upper part of the lifting mechanism 5 and acts on all material boxes 10 on the layer to be unstacked, and then the material boxes 10 are continuously pushed forwards to the material box output line 4 synchronously. After all the material boxes 10 reach the designated positions on the material box output line 4, the material pushing power assembly 62 provides translation power for the horizontal sliding table module 63, and the horizontal sliding table module 63 drives the material pushing rod 61 to horizontally and linearly move and return to the initial position so as to avoid position interference with the lifting mechanism 5 in lifting action. The horizontal pushing mechanism 6 has the advantages of simple structure, small occupied volume, high running stability and reliable action, and is particularly suitable for the unstacking and conveying production line 01.
In the long-term use process, the material pushing rod may be deviated in position, in the material pushing process, due to uneven stress, the pushing path of the material box 10 may be changed, even the material pushing fails, and so on, and in order to facilitate early identification of the deviation condition of the position of the material pushing rod 61, as shown in fig. 5, the material pushing rod 61 includes a horizontally arranged long straight rod 610 and a plurality of protruding portions 611; the long straight rod 610 is vertical to the material pushing direction of the horizontal material pushing mechanism 6; the protrusions 611 extend from the long straight rod 610 in the pushing direction, and the protrusions 611 correspond to the positions of the magazine 10 one by one. By arranging the protrusions 611 in the position of the cartridge 10 in a one-to-one correspondence, it is possible to quickly determine whether there is a position deviation by testing the actual positions of the protrusions 611 and the cartridge 10. Once the trend of position deflection occurs, the alarm prompt can be triggered to remind a worker to correct the position of the horizontal pushing mechanism 6 in time, so that the abnormal accident that the material box 10 is pushed out is avoided.

The working principle of the horizontal sliding table module 63 is as follows: the second servo motor 620 provides power, and drives the screw rod of the traverse ball screw to rotate along with the rotation of the output shaft of the second servo motor 620. Because the traverse slide block is slidably disposed on the parallel traverse slide rail 630, the middle portion of the traverse slide block is fixedly connected to the nut of the traverse ball screw, and the nut of the traverse ball screw drives the traverse slide block and the material pushing rod thereon to linearly move along the parallel traverse slide rail 630 on the screw of the traverse ball screw. The horizontal sliding table module 63 is simple in structure, small in occupied size, high in running stability and reliable in action, can realize quick positioning, and is convenient for realizing full-automatic horizontal material pushing control.
In order to provide a low-cost and easy-to-maintain cartridge output line, further, as shown in fig. 1 and 4, the cartridge output line 4 is a belt conveyor.

In order to solve the technical problem that the work efficiency of the mode of unstacking and conveying one by one is low, embodiment 2 provides a method for unstacking and conveying, which adopts the unstacking and conveying production line 01 provided by embodiment 1, and at least comprises the following steps:
s1: the tray carrying a plurality of material boxes is conveyed to an inner roller way of the lifting mechanism along the lower layer integral input line;
s2: the lifting mechanism lifts the tray and all the material boxes on the tray together along with an inner roller way of the lifting mechanism until the material box with the lowest height on the tray is flush with the output line of the material box, and the lifting mechanism stops lifting action and keeps the height of the tray unchanged;
s3: the horizontal pushing mechanism acts on the layer material box, so that the layer material box is unstacked from the lifting mechanism to the material box output line;
s4: step S2 to step S3 are the process of unstacking the material boxes in one layer, and step S2 to step S3 are repeated until the unstacking of all the material boxes is completed;
s5: the lifting mechanism lifts the empty tray along with the roller path in the lifting mechanism until the tray is flush with the output line of the tray, and stops lifting action and keeps the height of the tray unchanged;
s6: the roller way driving tray in the lifting mechanism is conveyed to a tray output line by the lifting mechanism.
The unstacking and conveying method provided by the embodiment 2 is based on the characteristics of a multilayer structure of orderly layout of the tray 1, and the aim of unstacking and conveying the material boxes 10 and the goods therein layer by layer is fulfilled by subtly arranging the relative positions of the tray 1 (see fig. 2), the lower layer integral input line 2, the upper layer tray output line 3, the material box output line 4, the lifting mechanism 5 and the horizontal pushing mechanism 6. Specifically, the lifting mechanism 5 adjusts the layer of the material boxes 10 to be unstacked to the height flush with the horizontal pushing mechanism 6, and at the height, all the material boxes 10 on the layer to be unstacked can be quickly and synchronously pushed into the material box output line 4 through the pushing action of the horizontal pushing mechanism 6. The magazine output line 4 then carries the magazines 10 thereon to further processing or transport. After all the material boxes 10 are unstacked, the tray 1 is continuously lifted upwards through the lifting mechanism 10, so that the inner roller way 50 of the lifting mechanism can be quickly butted with the output line 3 of the upper tray; the tray 10 is driven by the inner roller way 50 of the lifting mechanism to be conveyed to the tray output line 3 by the lifting mechanism 5, the transfer conveying of the empty tray 1 is completed, and the tray output line 3 can be used as a part of a return line of the empty tray 1, so that conditions are created for the automatic return of the empty tray 1. The unstacking and conveying method provided by the embodiment 2 realizes the layer-by-layer unstacking and conveying of the material boxes 10 and the automatic backflow conveying of the empty trays 1, and compared with the traditional mode of unstacking and conveying one by one, the method does not need to accurately position and split the single material box 10, reduces the positioning precision requirement and the positioning frequency, simplifies the step of unstacking and conveying, and greatly improves the working efficiency of unstacking and conveying and the reliability of mechanical operation.
In order to realize continuous automatic unstacking conveying, the method further comprises, after step S6:
s7: when the tray is detected to reach the tray output line, the lifting mechanism descends until the height of the inner roller way of the lifting mechanism is flush with the height of the lower layer integral input line. The steps S1 to S7 can be performed in a loop to achieve the purpose of continuous unstacking and conveying.
Because the subsequent processes need to perform modified atmosphere packaging on the material boxes, the existing automatic modified atmosphere packaging machine can only package a certain number of material boxes (equal to the number of synchronous packaging positions) synchronously, and the pressure conditions required by the packaging of the automatic modified atmosphere packaging machine cannot be ensured when the number of the material boxes is less than or more than the number of the material boxes, so that the automatic modified atmosphere packaging machine cannot work normally. The method for intelligently packaging the magazines is provided for the number change of the magazines unstacked to the output line of the magazines in each layer, and further comprises the following steps after the step S1 and before the step S2: the lifting mechanism 5 identifies the goods information of the material box 10 on the tray through a machine; goods information is uploaded to an upper computer system; ways of machine identifying the item information of the magazine on the tray include, but are not limited to: an RFID reader-writer is arranged on the lifting mechanism 5; an RFID electronic tag is arranged on the tray 1, and the RFID electronic tag is written with the goods information of the material box 10 on the tray 1; the RFID reader/writer is used for reading the RFID electronic tag on the tray 1. By providing the RFID tag at a designated position of the tray 1, accurate and efficient identification by the RFID reader can be ensured during dynamic conveyance. Through the cooperation of the RFID electronic tag written with the goods information and the RFID reader-writer, the goods information reaching the lifting mechanism 5 can be quickly acquired. The RFID reader-writer is easy to operate and control, simple and practical and particularly suitable for automatic control, and the identification work does not need manual intervention and contact; the RFID reader-writer is convenient and fast to read and high in safety. The RFID reader-writer can better guarantee the accuracy and the high efficiency of the goods information acquisition. The obtained goods information can be uploaded to an upper computer to realize real-time positioning and tracking of goods in the material box 10 and prepare for subsequent packaging of the material box 10: for example, the goods information corresponding to the material boxes 10 is sequentially sent to the printer of the packaging machine according to the arrangement sequence of the material boxes 10, so that the printing preparation work is done in advance, the goods information and the material boxes 10 can strictly correspond one to one, and the automatic packaging and printing are favorably realized.
Step S3 specifically includes: the horizontal pushing mechanism acts on the layer material box, so that the layer material box is unstacked from the lifting mechanism to the material box output line; the output line of the material boxes detects the number of the material boxes and determines whether the material boxes go to the automatic material box packaging conveying line or the manual material box packaging conveying line according to the detected number of the material boxes; the upper computer system uploads the goods information to a printer of a corresponding packing machine for printing in sequence according to the direction of the material box. The output line of the material boxes detects the number of the material boxes and determines whether the material boxes go to the automatic material box packaging conveying line or the manual material box packaging conveying line according to the detected number of the material boxes; the upper computer system uploads the goods information to a printer of a corresponding packing machine for printing in sequence according to the direction of the material box. According to the difference of the number of the material boxes from each layer of unstacking to the output line of the material boxes, corresponding intelligent packaging methods are respectively provided, so that the equipment faults are reduced, and the overall efficiency of the unstacking conveying production line 01 is improved.
The manner of detecting the number of cartridges by the cartridge output line includes, but is not limited to: a certain number of photoelectric sensors 40 are arranged at the input end of the material box output line 4; the photoelectric sensor 40 is used to detect whether the cartridge 10 reaches a specified position. The number of the photoelectric sensors 40 is equal to the number of the synchronous packaging positions of each row of the material boxes 10 when the tray 1 is fully loaded, and the photoelectric sensors 40 are arranged in one-to-one correspondence with the material boxes 10. Can detect the position of the magazine of unstacking to the magazine output line through photoelectric sensor 40, through carrying out assay count with photoelectric sensor 40 testing result, can obtain the magazine 10 quantity of each layer of unstacking to magazine output line 4 to in advance carry out manual handling alone with the magazine 10 of unsatisfied quantity. Thereby preventing the batch packs 10 from reaching the automatic modified atmosphere packaging machine and causing operational failure of the automatic modified atmosphere packaging machine.
Specifically, the automatic packaging conveying line comprises an automatic air conditioning packaging machine, and the automatic air conditioning packaging machine comprises a plurality of synchronous packaging positions; in step S3, "the number of magazines detected by the magazine output line and whether the magazine automatic packing line or the magazine manual packing line is to be sent to the magazine automatic packing line or the magazine manual packing line is determined based on the detected number of magazines" specifically: when the number of the detected material boxes is equal to the number of the synchronous packaging positions on the automatic air-conditioning packaging machine, the material box output line conveys the corresponding material boxes to the automatic material box packaging conveying line; otherwise, the magazine output line conveys the corresponding magazine to the magazine manual packaging conveying line. When the number of the material boxes is detected to be equal to the number of the synchronous packaging positions, the material box output line 4 rotates forwards to drive the material box output line 4 to go to the automatic material box packaging conveying line; when detecting that magazine quantity is less than the quantity of synchronous packing position, magazine output line 4 reverses, drives magazine output line 4 and goes to magazine manual packing transfer chain. The batch box 10 is to complete synchronous automatic packaging and labeling on an automatic modified atmosphere packaging machine on an automatic packaging and conveying line of the material box, wherein labeling information is transmitted to goods information of an upper computer from the lifting mechanism 5. Or the batch material boxes 10 are manually packaged and labeled one by one on a manual packaging machine on a manual packaging conveying line of the material boxes, wherein labeling information is transmitted to the goods information of the upper computer from the lifting mechanism 5. The unstacking conveying production line 01 provided by the preferred embodiment can classify different material boxes, so that faults are reduced, and the overall efficiency of the unstacking conveying production line 01 is improved.
