Detailed Implementation

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] Please see Figures 1-11 As one embodiment of the present invention, the single-row egg loading machine includes:

[0054] The base frame 1 is horizontally set on the workbench. The base frame 1 is a frame structure, which is fixed by multiple intersecting load-bearing beams. While improving the overall load-bearing strength of the base frame 1, it saves materials to the maximum extent and reduces weight.

[0055] An egg conveying structure is provided, which is located on one side above the base frame 1. An egg tray conveying track 39 is installed on the other side of the base frame 1. The egg conveying structure is used to carry eggs to be trayed and to convey them intermittently to the egg tray side. The direction in which the egg conveying structure conveys eggs is perpendicular to the direction in which the egg tray conveying track 39 conveys egg trays. Since the egg conveying structure conveys eggs intermittently rather than continuously, the squeezing force between eggs can be reduced, thus reducing the risk of breakage during the egg conveying process.

[0056] A guide platform 4 is fixed above the chassis 1, and is arranged between the egg conveying structure and the egg tray conveying track 39; the guide platform 4 is flush with the upper part of the egg conveying structure, and symmetrical surrounding fences 40 are arranged on both sides of the guide platform 4; the surrounding fences 40 arranged symmetrically on both sides of the guide platform 4 form an arrangement channel therebetween, one end of the arrangement channel towards the egg conveying structure is an egg inlet, and the other end towards the egg tray is an egg outlet; the egg inlet is butted to the side of the egg conveying structure towards the egg tray, the opening and closing degree of the egg outlet is smaller than that of the egg inlet, the surrounding fences 40 smoothly transition between the egg outlet and the egg inlet; wherein the opening and closing degree of the egg outlet is only suitable for a single egg to pass through. The egg conveying structure intermittently conveys the eggs through the egg inlet to the guide platform 4, and the eggs conveyed to the guide platform 4 continue to roll towards the egg tray under the pushing force of the rear eggs (the eggs on the egg conveying structure); the rolling eggs are guided by the surrounding fences 40 on both sides of the guide platform 4, so that the eggs are continuously gathered during rolling, and finally discharged one by one through the egg outlet.

[0057] An arrangement assembly is also arranged on the chassis 1, and is mechanically interlocked with the egg conveying structure, and is arranged below the egg outlet on the side close to the egg conveying structure; the arrangement assembly is used to equidistantly space the eggs discharged one by one from the egg outlet, and lay some of the standing eggs flat, so that the eggs are horizontally laid on the upper side of the egg tray conveying track 39. During the conveying of the eggs, most of the eggs remain horizontally laid on the table, and a small part of the eggs stand up due to the squeezing force; the arrangement assembly arranged in the present application can ensure that all the eggs are in a horizontal state when conveyed to the upper side of the egg tray conveying track; and the two adjacent eggs can be equidistantly separated.

[0058] An egg loading mechanism is arranged on one side of the arrangement assembly and above the egg tray conveying track 39, and is mechanically staggered with the arrangement assembly to vertically push the eggs horizontally and neatly laid on the upper side of the egg tray conveying track 39 into the egg pits in the egg tray during the pause gap of the egg conveying. Wherein, the egg loading mechanism and the arrangement assembly are mechanically staggered to realize that the eggs are not loaded during conveying, and the eggs are not conveyed during loading; the mechanical cooperation and mechanical interlocking are adopted to establish cooperation between multiple functional structures, assemblies and mechanisms, on the one hand, the precision is higher and the error is smaller; on the other hand, the problems of high difficulty, high failure rate and high maintenance cost of the electric control and sensing control module can be avoided.

[0059] In detail, the existing automatic or semi-automatic egg packing machine mostly needs to cooperate with various electronic controllers and photoelectric sensors to realize the cooperation of multiple functional structures, such as common timers, infrared sensors, programmable hosts, servo systems and the like, and there are high-cost components, and the cost of the whole equipment is also high. Moreover, the fault rate of the electric control and light sensing devices is high, and the error is relatively large. When one egg is not effectively detected or sensed, it will affect the packing of all subsequent eggs.

[0060] Of course, part of the automatic egg packing machine also sets up a correction system. Although the correction system can greatly reduce the packing error, it also further increases the cost of the whole equipment.

[0061] As we all know, although the fault rate of electric control and sensing components tends to be mature, the service life and fault rate are constantly extended, but compared with mechanical components, the service life and fault rate are still unstable. Moreover, if the electric control and sensing components fail, they are basically replaced in modules and cannot be repaired, which increases the maintenance cost.

[0062] Finally, since the electric control and sensing components and the servo system need to be controlled by PLC programming, the professional quality of the operator is also required to be high.

[0063] In summary, for the PLC controlled egg packing machine using electric control and sensing and servo system, although the logic is clearer, the artificial quality requirement, equipment cost and maintenance cost are higher, and it is not friendly to small and medium-sized enterprises, especially small packaging manufacturers.

[0064] As a further scheme of the present application, the egg conveying structure comprises two parallelly arranged belt rollers 2 and a conveying belt 3 connected between the two belt rollers 2, the upper part of the conveying belt 3 is flush with the guide platform 4, and the surface of the conveying belt 3 is uniformly distributed with a plurality of protrusions.

[0065] Among them, the roller frame is vertically fixed and installed on both sides of the chassis 1, and the two belt rollers 2 are rotatably arranged on the roller frame, and one of the belt rollers 2 is mechanically interlocked with the arrangement assembly.

[0066] In actual application, a protective plate is arranged on both sides of the conveying belt 3, and the protective plate is installed on the chassis 1 to prevent the eggs on the conveying belt 3 from rolling off from both sides of the conveying belt 3.

[0067] When the arrangement assembly is in operation, one of the belt rollers 2 is driven to rotate, and the other belt roller 2 is synchronously rotated under the action of the conveying belt 3, so that the conveying belt 3 connecting the two belt rollers 2 operates and intermittently conveys the eggs to the guide platform 4; the protrusions distributed on the surface of the conveying belt 3 can play the role of anti-skid and resistance increase, which can avoid the free rolling of the eggs on the conveying belt 3, and can also ensure that the eggs on the conveying belt 3 can provide sufficient extrusion force for the eggs on the guide platform 4 when the conveying belt 3 operates, so as to drive the eggs on the guide platform 4 to roll from the egg inlet to the egg outlet.

[0068] As a further scheme of the present application, the arrangement assembly comprises a flattening structure located below the egg outlet on one side, and the flattening structure is mechanically locked with one of the belt rollers 2; the flattening structure is used to flatten the erected eggs discharged from the egg outlet.

[0069] The arrangement assembly further comprises a separation structure arranged directly above the egg tray conveying track 39, and the side of the flattening structure close to the egg tray is transitioned to the side of the separation structure away from the egg tray through the slide 13; the separation structure is mechanically locked with the flattening structure, and the surface of the slide 13 is in the shape of a central concave "U".

[0070] Since the eggs are transitioned from the flattening structure to the separation structure through the slide 13 by relying on the gravitational potential energy, the process of the transition and rolling of the eggs is an acceleration process; in order to avoid the breakage of the eggs due to the too large rolling speed of the eggs, a plurality of anti-skid blocks are uniformly arranged on the upper surface of the slide 13 to reduce the acceleration of the rolling of the eggs on the slide 13. The slide 13 is arranged in the shape of a central concave "U" to avoid the sliding of the eggs from the two sides of the slide 13.

[0071] As a further scheme of the present application, the flattening structure comprises a first chain roller 7 and a second chain roller 8 which are parallel to each other, and the first chain roller 7 and the second chain roller 8 are linked through two groups of chain clamps 9.

[0072] A plurality of supporting rollers 10 are rotationally arranged between the two groups of chain clamps 9, the first chain roller 7 and the second chain roller 8 are rotationally installed on a side frame, and the side frame is fixedly installed on the base frame 1.

[0073] Small gears 11 are fixed to the end portions of the supporting rollers 10, a gear plate 12 adapted to the small gears 11 is horizontally installed on the side frame; one end of the first chain roller 7 is provided with a first transmission shaft 6, and the first transmission shaft 6 is connected with one of the belt rollers 2 through a first transmission belt 5.

[0074] Since the two adjacent supporting rollers 10 can form a pit, and the multiple supporting rollers 10 form multiple continuous pits, the eggs discharged one by one from the egg outlet can fall into each pit one by one; and the supporting rollers 10 on both sides of the pit with the egg fall under the action of the pinion 11 and the toothed plate 12, move to the separation structure to convey the egg, and rotate to adjust the egg in the pit from the standing state to the lying state; so as to ensure that the eggs are all in the flat state before entering the slide 13.

[0075] As a further scheme of the present application, the chassis 1 is provided with a motor 14, one end of the second chain roller 8 is provided with a first driven wheel 28, and the output shaft of the motor 14 is provided with a driving wheel 27 intermittently matched with the first driven wheel 28;

[0076] The driving wheel 27 and the first driven wheel 28 form a set of Malta cross movement core; and a large pulley is coaxially fixed on one side of the driven wheel 27, and the large pulley is connected with the separation structure through a second transmission belt 29.

[0077] The motor 14 drives the driving wheel 27 to rotate through the output shaft, and the driving wheel 27 drives the second chain roller 8 and the large pulley to rotate intermittently through the cooperation with the first driven wheel 28; wherein the second chain roller 8 drives the first chain roller 7 and the first transmission shaft 6 to rotate synchronously and intermittently under the action of the chain 9, and the large pulley drives the separation structure to work intermittently through the second transmission belt 29.

[0078] Specifically, the intermittent rotation of the first chain roller 7 and the second chain roller 8 makes the chain 9 run intermittently, so that the supporting roller 10 and the pit formed between the two adjacent supporting rollers 10 intermittently convey the eggs; and the intermittent rotation of the first transmission shaft 6 can drive the belt roller 2 to rotate intermittently, so that the eggs on the conveying belt 3 are synchronously and intermittently conveyed into the arrangement channel, avoiding the over-concentration of continuous conveying pressure to cause the breakage of part of the eggshell.

[0079] As a further scheme of the present application, the separation structure comprises a first conveying roller 15 and a second conveying roller 16 arranged in parallel, and the first conveying roller 15 and the second conveying roller 16 are connected through a conveying belt 17, and multiple soft partitions are arranged on the conveying belt 17 at equal intervals, and a slot is formed on the conveying belt 17 between the two adjacent partitions;

[0080] The first conveying roller 15 and the second conveying roller 16 are both rotatably installed on an assembly frame 38, and the assembly frame 38 is fixed on the chassis 1; the slide 13 is arranged between the second chain roller 8 and the first conveying roller 15, a second transmission shaft 30 is coaxially fixed on one side of the first conveying roller 15, and the second transmission belt 29 connects the large pulley and a small pulley fixed on the second transmission shaft 30.

[0081] When the roller 10 is running, the second transmission shaft 30 is also running through the second transmission belt 29, that is, the conveying belt 17 is also running, so that the eggs are separated from the pits and fall one by one on the upper part of the slide 13, and the eggs falling one by one on the slide 13 roll into each slot on the conveying belt 17 one by one, so that the eggs lie horizontally on the conveying belt 17 and are directly above the egg tray conveying track 39.

[0082] As a further scheme of the present application, the egg loading mechanism comprises a transmission assembly cooperating with the first driven wheel 28 to drive the driving wheel 27, a pushing structure connected to the transmission assembly, and a buffer guide assembly arranged on one side of the assembly frame 38.

[0083] The pushing structure is used to push the eggs lying horizontally on the conveying belt 17 off the conveying belt 17 at the same time and into the buffer guide assembly; the buffer guide assembly is used to receive the eggs pushed off and absorb the momentum of the eggs, so that the eggs vertically slide into the pits in the egg tray.

[0084] The pushing structure comprises a support frame 21 fixed on one side of the assembly frame 38, a push rod 18 horizontally slidingly matched with the support frame 21, a rubber bowl 19 fixed on one end of the push rod 18 and adjacent to the conveying belt 17, and a cross beam 20 fixed on the other end of the push rod 18; the cross beam 20 is connected with the transmission assembly.

[0085] Since the transmission assembly cooperates with the first driven wheel 28 to drive the driving wheel 27, when the first driven wheel 28 is running to convey the eggs, the transmission assembly does not act, that is, the pushing structure does not act; after the first driven wheel 28 stops running, the transmission assembly cooperates with the driving wheel 27 to push the eggs on the stationary conveying belt 17, so that the conveying and loading of the eggs are carried out step by step and orderly, without interference.

[0086] When the transmission assembly is actuated, the push rod 18 is horizontally alternately moved through the cross beam 20 to drive the rubber bowl 19 to be horizontally alternately moved, so as to push the eggs in each slot on the conveying belt 17.

[0087] As a further scheme of the present application, the buffer guide assembly comprises a plurality of clamping structures arranged side by side, the clamping structure comprises two oppositely arranged reversing guide plates 22, the two reversing guide plates 22 form a "Y" shape with a large upper opening and a small lower opening, and a clamping groove is formed on each reversing guide plate 22 to form an "n" shape.

[0088] The reversing guide plate 22 away from the conveying belt 17 is mounted on the mounting plate 26 fixed on the chassis 1 through an elastic structure, which comprises a fixed column 25 horizontally fixed on the mounting plate 26 and a buffer sleeve 23 horizontally fixed on the back of the reversing guide plate 22, the buffer sleeve 23 is slidably sleeved with the fixed column 25, and the two are elastically matched through the spring 24.

[0089] Since the two reversing guide plates 22 form a “Y” type clamping structure, and the upper opening of the clamping structure is large, it can be ensured that the pushed and fallen eggs can completely fall into the clamping structure; and since the lower opening of the clamping structure is small, and the eggs falling onto the upper opening of the clamping structure can be ensured to fall vertically under the action of the clamping groove, and then fall vertically into the egg pits on the egg holder;

[0090] The elastic structure can buffer and absorb the momentum of the eggs when falling on one hand during the process of the eggs falling into the clamping structure and the process of the eggs sliding in the clamping structure; on the other hand, it can also provide elastic friction for the eggs during the process of the eggs sliding in the clamping structure, so as to reduce the falling speed of the eggs and avoid the eggs from being broken due to too fast speed when falling into the egg pits.

[0091] As a further scheme of the present application, the transmission assembly comprises a second driven wheel 31 rotatably arranged on the chassis 1, a rotating shaft 34 horizontally rotatably arranged on the chassis 1 and connected with the second driven wheel 31 through a bevel gear set, a pushing shaft 36 rotatably arranged on the chassis 1 in parallel with the rotating shaft 34, a third transmission belt 35 connecting the pushing shaft 36 and the rotating shaft 34, and a connecting rod 37 connecting the pushing shaft 36 and the cross beam 20.

[0092] The first driven wheel 28 and the second driven wheel 31 are symmetrically arranged on the upper and lower sides of the driving wheel 27, one end of the connecting rod 37 is rotatably connected with the eccentric part of the end of the pushing shaft 36, and the other end is rotatably connected with the cross beam 20.

[0093] The driving wheel 27 and the second driven wheel 31 form another set of Maltese cross movement core; the bevel gear set comprises a first bevel gear 32 fixed coaxially with the second driven wheel 31 and a second bevel gear 33 fixed coaxially with the rotating shaft 34, and the second bevel gear 33 and the first bevel gear 32 are engaged with each other.

[0094] The first driven wheel 28 and the second driven wheel 31 are symmetrically arranged on the upper and lower sides of the driving wheel 27, so when the driving wheel 27 drives the first driven wheel 28 to rotate, the second driven wheel 31 is stationary; on the contrary, when the driving wheel 27 drives the second driven wheel 31 to rotate, the first driven wheel 28 is stationary, so that the peak-shifting cooperation of the egg loading mechanism and the arrangement assembly can be realized.

[0095] In detail, the second driven wheel 31 is rotated to drive the first bevel gear 32 to rotate, and the first bevel gear 32 drives the rotating shaft 34 to rotate through the second bevel gear 33; the rotating shaft 34 drives the pushing shaft 36 to rotate through the third transmission belt 35, and the pushing shaft 36 drives the connecting rod 37 to drive the cross beam 20 to horizontally reciprocate once, so as to push the eggs on the groove to fall.

[0096] The application further provides a method for loading eggs by using the single-row egg loading machine.

[0097] Step one, egg loading and unloading, the eggs to be loaded are placed on the conveying belt 3 through the vacuum egg suction device, and the positions of the egg trays on the egg tray conveying track 39 are adjusted in advance, so that the first row of egg pits of the egg trays is aligned below each group of clamping structures;

[0098] The egg trays are intermittently pushed on the egg tray conveying track 39, and the interval of each time of pushing is the distance between the two adjacent rows of egg pits, and the egg tray conveying line is an application of the prior art, which will not be described here.

[0099] Step two, pre-conveying, the motor 14 is started to orderly pass the eggs through the arrangement channel and horizontally arrange the eggs in the groove on the conveying belt 17 through the flattening structure and the separation structure; when the first row of eggs is pushed into the first row of the egg tray by the pushing structure, the egg tray conveying line is opened to ensure that the pushing structure does not act during the process of pushing the egg tray by the egg tray conveying line; if the pushing structure acts during the process of pushing the egg tray, the motor 14 needs to be immediately stopped and then the egg tray conveying line is closed, and then it is readjusted.

[0100] It is noted that in the example shown in the drawings of the application, the two groups of Maltese cross cores are four-equal-part matching ratios, and the first driven wheel 28 and the second driven wheel 31 are symmetrically arranged on the upper and lower sides of the driving wheel 27; therefore, not immediately after the driving wheel 27 is separated from the first driven wheel 28, the driving wheel 27 cooperates with the second driven wheel 31, and there is a pause for a period of time in between.

[0101] For example, the driving wheel 27 rotates for 12s, and according to the example shown in the drawings of the application, the driving wheel 27 cooperates with the first driven wheel 28 for 3s, and then cooperates with the second driven wheel 31 after 3s; similarly, the driving wheel 27 cooperates with the second driven wheel 31 for 3s, and then cooperates with the first driven wheel 28 after 3s.

[0102] Therefore, during the pre-conveying stage, the time interval for opening the egg tray conveying line is within 3s, which greatly reduces the difficulty of controlling the opening time of the egg tray conveying line.

[0103] Step three, running off, after all the eggs on the conveying belt 3 are packed (in the process of packing, the vacuum egg suction device can also continuously add eggs to the conveying belt 3), first observe whether there are eggs left on the guide platform 4 (generally, there will be some eggs, because the eggs on the conveying belt 3 have all entered the guide platform 4, so there is no subsequent egg to provide extrusion force to the eggs on the guide platform 4 through the running conveying belt 3), if there are eggs on the guide platform 4, the eggs can be manually pushed into the flat structure until there are no eggs left on the guide platform 4;

[0104] Then check whether there are eggs left on the flat structure, the separation structure and the conveying belt 17 in turn; when there are no eggs left on the flat structure, the separation structure and the conveying belt 17, stop the motor 14, and then close the egg tray conveying line to take the egg tray on the egg tray conveying track 39.

[0105] The above examples are exemplary rather than limiting, and therefore, the technical solutions of the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
