Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a posture adjustment mechanism for a net packing machine for harvested apples. Background Art

[0002] At present, the development of my country's fruit industry is becoming more and more rapid, and the output of apples is also increasing year by year. In orchards or agricultural industrial bases, apples need to be transported to various regions after being picked, and some regions are even far away. In the process of loading or transporting apples, collisions or squeezing are inevitable, which will cause damage to the apples and cause unnecessary losses. To deal with this situation, most people use the method of putting foam nets on apples. This method has a good protective effect on apples, but manual packaging has the problems of high labor intensity and high labor costs. Therefore, in order to further develop the apple industry, it is necessary to provide a net packing machine for post-harvest apples. Here, a posture adjustment mechanism for a net packing machine for post-harvest apples is provided.

When packaging is performed in this state, the net completely wraps the apple flesh, leaving the apple handle and pedicel slightly exposed; the other end of the posture adjustment telescopic rod is set with an arc surface to touch and move the apple; to prevent the apple from being bruised, the end of the posture adjustment telescopic rod that contacts the apple is made of flexible material or is sleeved with a flexible sleeve.

[0004] The problem is that no matter what the state of the apple is in the rotating apple posture adjustment plate, the posture adjustment telescopic rod will work, and its end will move the apple in the apple posture adjustment slot to rotate; in addition, for apples with different postures, the end of the posture adjustment telescopic rod moves the apple in the apple posture adjustment slot when the posture adjustment telescopic rod rotates, so that the apple is rotated; thereby, the apple is positioned with the handle side facing down after the rotating plate rotates, that is, the posture adjustment telescopic rod is only a mechanical action, and it is not precisely adjusted for different postures.

[0011] The transmission auxiliary component is provided with a driving motor, a magnetic fixed segment, and a special tray, and the special tray is magnetically connected to the magnetic fixed segment; the magnetic fixed segment is provided with a connecting part, and the connecting part is provided with a lifting through hole, and the lifting through hole accommodates the lifting and lowering of the posture adjustment disk; the rising of the posture adjustment disk drives the special tray to separate from the magnetic fixed segment, so that the special tray is lifted to the bottom of the vacuum suction component above to receive the apples; the descent of the posture adjustment disk drives the special tray to descend and then be magnetically adsorbed together with the magnetic fixed segment; the central part of the special tray is an apple accommodating chamber, which is used to accommodate and transport apples, and there is an upward protrusion on the bottom surface at the center of the apple accommodating chamber, which cooperates with any one of the recessed parts at both ends of the apple; the driving motor drives the magnetic fixed segments arranged at intervals along the chain through a chain sprocket transmission.

[0012] The working principle or process of the utility model is as follows:

[0013] At the feeding end, the rear push cylinder drives the accordion suction cup to suck the apples from the feeding mechanism and then retract them. When retracting, the apples are adsorbed on the accordion suction cup. After the camera captures the image of the apple, the image processing component determines whether it is a bad fruit. If so, the accordion suction cup stops adsorbing after being driven to move outward. After stopping adsorption, the bad fruit leaves the accordion suction cup, falls to the conveying mechanism on that side, and is then conveyed out. If the fruit is good, the forward-pushing cylinder will suck up the accordion-type suction cup and send the apples with adjusted posture to the air above the apple packaging machine for packaging; the lower lifting auxiliary component will rise first to lift up the special tray, and if necessary, the positioning motor in the posture adjustment component will rotate, adjust the posture of the posture adjustment plate and then rise until it contacts the apple, and the accordion-type suction cup will release the apple after contact; if necessary, the positioning motor will rotate again to adjust the posture adjustment plate to a horizontal level, and then when the lifting auxiliary component descends, the special tray will stay on the magnetic fixed segment, and the apples will continue to be transported as the magnetic fixed segment moves; during continued transportation, the next special tray will be transported to the top of the posture adjustment component, and the lower lifting auxiliary component will rise first to lift up the special tray, and the above actions will be repeated to achieve continuous work.

[0014] At the discharge end, the apples are continuously conveyed along with the movement of the magnetic fixed segments. When they are conveyed to the bottom of another accordion-type suction cup, the adsorption lifting component drives the accordion-type suction cup to move downward and contact the apples. Then the vacuum generator works to make the accordion-type suction cup adsorb the apples, and then the forward pushing cylinder works to convey the apples away from the posture adjustment component to the packaging process.

[0015] The positioning motor under the posture adjustment disk drives the positioning connecting rod to rotate; the positioning connecting rod is extended or contracted during the driven rotation process. The above arrangement drives an adjusting connecting rod to rise and fall to one side to adjust the posture of the posture adjustment disk, so as to achieve precise adjustment to suit the posture of the apple; the posture of the special tray is adapted to the posture of the apple, and after rising to contact the apple, the accordion suction cup stops adsorption, and the apple falls into the special tray. At this time, the apple and the special tray are not level, and the positioning motor runs again to adjust the posture adjustment disk to a horizontal level, and the apple will also be adjusted to a horizontal level, completing the posture adjustment process. For postures that do not need to be adjusted, the positioning connecting rod does not need to move.

The posture adjustment disk 1001 is provided with positioning links 1002 at intervals along its side. Each positioning link 1002 has the same structure and is divided into two hinged parts. One end of the positioning link 1002 is connected to the posture adjustment disk 1001, and the other end of the positioning link 1002 is connected to the positioning motor 1010. The positioning motor 1010 drives the positioning link 1002 to rotate; the positioning link 1002 extends or contracts during the driven rotation process.

[0049] The lifting auxiliary component 2000 includes a lifting transmission connecting piece and a lifting motor 2014. The lifting motor 2014 is connected to drive the posture adjustment component 1000 to lift and lower through the lifting transmission connecting piece.

[0050] The functional auxiliary component 3000 includes an imaging component and a vacuum suction component; there are two vacuum suction components, one at the feed end and one at the discharge end, wherein the vacuum suction component at the feed end is provided with an imaging component, the vacuum suction component is connected to the adsorption driving component, the adsorption driving component is provided with an adsorption translation component and an adsorption lifting component, the adsorption translation component drives the vacuum suction component to reciprocate along the conveying direction of the apple 3008, and the adsorption lifting part drives the vacuum suction component to rise and fall; the imaging component is provided with a camera 3016 and an image processing component 3015, the camera 3016 takes an image of the apple 3008 sucked by the vacuum suction component and transmits the image to the image processing component 3015, the image processing component 3015 confirms whether the surface of the apple 3008 is damaged according to the image; the vacuum suction component is provided with a vacuum generator 3006 and an accordion suction cup 3007, the vacuum generator 3006 is connected to the accordion suction cup 3007 and controls the operation of the accordion suction cup 3007.

[0051] The transmission auxiliary component 4000 is provided with a driving motor 4006, a magnetic fixing segment 4002, and a special tray 4003, wherein the special tray 4003 is magnetically connected to the magnetic fixing segment 4002; the magnetic fixing segment 4002 is provided with a connecting portion, and the connecting portion is provided with a lifting through hole, and the lifting through hole accommodates the lifting of the posture adjustment plate 1001; The posture adjustment disk 1001 rises and drives the special tray 4003 to separate from the magnetic fixed segment 4002, so that the special tray 4003 is lifted to the bottom of the vacuum suction component above to receive the apples 3008; the posture adjustment disk 1001 descends and drives the special tray 4003 to descend and then be magnetically adsorbed together with the magnetic fixed segment 4002; the center of the special tray 4003 is an apple accommodating chamber, which is used to accommodate and transport apples 3008. There is an upward protrusion on the bottom surface at the center of the apple accommodating chamber, and the protrusion cooperates with any one of the recessed parts at both ends of the apple 3008; the driving motor 4006 drives the magnetic fixed segments 4002 arranged at intervals along the chain through a chain sprocket transmission.

[0052] At the feeding end, the rear push cylinder 3013 drives the accordion-type suction cup 3007 to suck the apple 3008 from the feeding mechanism and then retract it. When retracting, the apple 3008 is adsorbed on the accordion-type suction cup 3007; the camera 3016 collects the image of the apple 3008 and the image processing component 3015 determines whether it is a bad fruit. If so, the adsorption is stopped after the accordion-type suction cup 3007 is driven to move outward. After the adsorption stops, the bad fruit separates from the accordion-type suction cup 3007, falls to the conveying mechanism on that side, and is then conveyed out. If the apple is good, the front pushing cylinder 3012 will suck up the accordion suction cup 3007 and send the apple 3008 with adjusted posture to the air above the apple packaging machine for packaging; the lower lifting auxiliary component 2000 will first rise to lift up the special tray 4003, if necessary, the positioning motor 1010 in the posture adjustment component 1000 will rotate to adjust the posture and then rise until it contacts the apple 3008, after which the accordion suction cup 3007 releases the apple 3008; if necessary, the positioning motor 1010 will rotate again to adjust the posture adjustment disk 1001 to a horizontal level, and then when the lifting auxiliary component 2000 descends, the special tray 4003 will stay on the magnetic fixing segment 4002, and the apple 3008 will continue to be transported as the magnetic fixing segment 4002 moves; during continued transportation, the next special tray 4003 will be transported to the top of the posture adjustment component 1000, and the lower lifting auxiliary component 2000 will first rise to lift up the special tray 4003, and the above actions will be repeated to achieve continuous work.

[0053] At the discharge end, the apple 3008 is continuously conveyed along with the movement of the magnetic fixed segment 4002. When it is conveyed to the bottom of another accordion-type suction cup 3007, the adsorption lifting component 3005 drives the accordion-type suction cup 3007 to move downward to contact the apple 3008. Then, the vacuum generator 3006 works to make the accordion-type suction cup 3007 adsorb the apple 3008, and then the forward pushing cylinder 3012 works to convey the apple 3008 to the packaging process in the direction away from the posture adjustment component.

[0054] The positioning motor 1010 below the posture adjustment disk 1001 drives the positioning connecting rod 1002 to rotate; the positioning connecting rod 1002 extends or contracts during the driven rotation. The above setting drives an adjusting connecting rod 1002 to rise and fall to one side to adjust the posture of the posture adjustment disk 1001, thereby achieving precise adjustment to the posture of the apple 3008, so that the posture of the special tray 4003 adapts to the posture of the apple 3008. After rising to contact the apple 3008, the accordion suction cup 3007 stops adsorbing, and the apple 3008 falls into the special tray 4003. At this time, both the apple 3008 and the special tray 4003 are tilted and uneven, and the positioning motor 1010 runs again to adjust the posture adjustment disk 1001 to a horizontal level, and the apple 3008 will also be adjusted to a horizontal level to complete the posture adjustment process; for postures that do not need to be adjusted, the positioning connecting rod 1002 does not need to move. The utility model can realize intelligent control and precise posture adjustment, ensure the losslessness of apple 3008, and lay a foundation for further foam net sleeve packaging of apple 3008.

[0055] The utility model discloses a posture adjustment mechanism for a net packing machine for post-harvest apples, which is composed of a posture adjustment component 1000, a lifting auxiliary component 2000, a function auxiliary component 3000 and a transmission auxiliary component 4000.

[0056] The posture adjustment component 1000 is fixed to the lifting auxiliary component 2000 by bolt connection, and the bolts specifically connect the fixed plate 1011 of the posture adjustment component 1000 and the top plate 2001 of the lifting auxiliary component 2000; the posture adjustment component 1000 is fixed to the support plate 4014 in the transmission auxiliary component 4000 by bolt connection through the fixed plate 1011; the primary frame 3002 of the functional auxiliary component 3000 is fixedly connected to the secondary frame 4001 of the transmission auxiliary component 4000.

[0057] refer to Figure 2 , Figure 3It can be seen that the lower part of the positioning connecting rod 1002 is a gear-integrated connecting rod, and the end of the gear-integrated connecting rod connected to the positioning motor 1010 is provided with a connecting rod gear, and the driving shaft of the positioning motor 1010 is provided with a positioning gear 1008, and the connecting rod gear is meshed and connected with the positioning gear 1008. The connecting rod gear is sleeved on the connecting shaft 1004, and the rotation of the positioning gear 1008 drives the connecting rod gear to rotate around the connecting shaft 1004.

[0058] There are three adjusting connecting rods 1002, and correspondingly, there are also three gear-integrated connecting rods, namely, type-one gear-integrated connecting rod 1005, type-two gear-integrated connecting rod 1006, and type-three gear-integrated connecting rod 1007; there is one connecting shaft 1004, and the three connecting rod gears are spaced apart and mounted on the same vertically arranged connecting shaft 1004.

[0059] The three positioning motors 1010 and the connecting shaft 1004 are all installed on the fixed plate 1011.

[0060] The fixing plate 1011 and the top plate 2001 are fixed by bolt connection.

[0061] When one of the positioning motors 1010 is driven and the other two positioning motors 1010 are not working, only the driven gear-in-one connecting rod will rotate with the connecting shaft 1004 as the axis, and the other gear-in-one connecting rods will not rotate; since the positioning connecting rod 1002 and the gear-in-one connecting rod are a plane pair, the driven gear-in-one connecting rod will force the positioning connecting rod 1002 to change its posture, and the upper end will rotate around the connecting roller 1003, so that one end of the posture adjustment disk 1001 close to the positioning connecting rod 1002 will be lifted or pressed down, if the positioning motor 1010 rotates forward, the positioning connecting rod 1002 driven by it will be lifted, and when the positioning motor 1010 rotates reversely, the positioning connecting rod 1002 will be lowered; the posture of the posture adjustment disk can be controlled by controlling the positioning motor 1010 to rotate forward or reverse, so that the posture of the special tray 4003 on it can be adjusted.

[0062] Similarly, if the three positioning motors 1010 rotate forward at the same time, the posture adjustment plate 1001 will be lifted, and when the three positioning motors 1010 rotate reversely at the same time, the posture adjustment plate 1001 will be lowered.

[0063] For adjusting the apple 3008 that is tilted to one side, the corresponding adjustment link 1002 can be controlled to rotate according to its posture, and the posture adjustment disk 1001 can be moved to one side by lifting to adjust the posture to adapt to the posture of the apple 3008; for the apple 3008 with adjusted posture, the adjustment link 1002 of the device does not need to work.

[0064] refer to Figure 4 , Figure 5It can be known that the lifting transmission connecting parts include a top plate 2001, a top column 2002, a support block 2006, a connecting bolt 2007, a limiting pillar 2008, a slider 2009, a cylindrical cam 2010, and a limiting bolt 2011; the top plate 2001 and the top column 2002 are fixedly connected by the support block 2006 and the connecting bolt 2007; the other end of the top column 2002 is connected to the slider 2009; the two ends of the slider 2009 are respectively sleeved on the limiting pillars 2008 at both ends, and the middle of the slider 2009 is sleeved with a cylindrical cam 2010; the end of the limiting bolt 2011 after passing through the slider 2009 cooperates with the arc-shaped track on the cylindrical cam 2010; the shaft end of the cylindrical cam 2010 is driven by the lifting motor 2014.

[0065] A rolling component is arranged at one end of the stop bolt 2011 that cooperates with the cylindrical cam 2010, so that the movement between the stop bolt 2011 and the cylindrical cam 2010 is a rolling movement. The rolling component, such as a rolling bearing, can effectively reduce the friction between the two components.

[0066] Two springs 2012 are respectively sleeved on two limiting pillars 2008. Considering that the lifting force is insufficient in the ascending process and cannot be lifted quickly, the spring 2012 is additionally provided to provide the lifting force, so that the lifting action is smoother and faster.

[0067] The first type fixing block 2003 and the second type fixing block 2005 connect the two lifting auxiliary component shells 2004.

[0084] refer to Fig.15 The overall structure of a posture adjustment mechanism for a net bag packaging machine for harvested apples is known.

[0085] refer to Fig.16 , Fig.17 It can be seen that the posture adjustment mechanism of this embodiment is applied to the post-harvest apple net bag packaging machine and is a three-dimensional diagram after assembly.

[0086] The working principle and working process of this component are as follows:

[0087] (1) When the apple 3008 is sent to the position above the posture adjustment position through the function auxiliary device 3000, the driving motor 4006 provides torque, the driving sprocket 4007 engages with the type 2 sprocket 4016 and transmits torque to the rotating shaft 4005, and the type 1 sprocket 4008 is driven by the rotating shaft to engage with the type 1 chain 4009 to realize the transmission of the special tray 4003 and the magnetic fixing segment 4002, and then the posture adjustment disk 1001 is sent to the bottom of the apple 4003 for posture adjustment.

[0088] (2) At the posture adjustment position, the vacuum generator 3006 provides a vacuum environment so that the accordion suction cup 3007 keeps sucking the apple 3008.

[0089] (3) The camera 3016 and the image processing component 3015 first analyze whether the apple 3008 is a bad apple. If so, they then push the cylinder 3013 to work and send the damaged apple 3008 away from the posture adjustment machine. If it is an intact apple 3008, the posture of the apple 3008 at this time is analyzed and the following steps are performed.

[0090] (4) At the posture adjustment position, the lifting motor 2014 works, the lifting auxiliary component 2000 provides lifting force for the posture adjustment component 1000, and lifts the posture adjustment component 1000 to a certain distance. The three positioning motors 1010 finally combine the posture adjustment ball provided in the middle of the special tray 4003 with the recessed part of the apple 3008 according to the results of the camera 3016 and the image processing component 3015.

[0091] (5) At this time, the vacuum generator 3006 stops achieving the vacuum environment, and the accordion suction cup 3007 releases the apple 3008; the lifting motor 2014 continues to work, and the lifting auxiliary component 2000 causes the posture adjustment component 1000 to descend back to its original position. During the return process, the three positioning motors 1010 in the posture adjustment component 1000 continue to work according to the actual situation to restore the special tray 4003 to its original posture. The apple 3008 changes its posture at the same time as the special tray 4003, so that the posture of the apple 3008 is adjusted from an arbitrary posture to a posture in which only the concave part of the apple 3008 is up and down.

[0092] (6) The driving motor 4006 continues to work and transports the apple 3008 a certain distance to the bottom of the next accordion-type suction cup 3007. The accordion-type suction cup 3007 sucks up the apple 3008. Under the action of the functional auxiliary component 3000, the forward pushing cylinder 3012 can assist in transporting the apple 3008 to the apple packaging location.

[0093] (7) All the structures of the whole machine operate in an orderly manner according to the control programming program, and finally the whole posture adjustment machine can work in an orderly manner. In combination with the post-harvest apple net packaging machine, the function of the posture adjustment machine can be fully utilized.
