Description

Technical Field

[0001] The present invention relates to the technical field of poultry egg packing, and particularly to a poultry egg packing device. Background Art

[0002] In the automated production of poultry egg packing, the egg tray separating mechanism is the core module connecting the egg tray conveying and the poultry egg filling. Its core function is to layer-separate the stacked empty egg trays and stably convey them to the filling station.

[0003] Although the current egg tray separating mechanism has been widely used in the field of automated poultry egg packing, there are still problems when dealing with tightly stacked egg trays. Specifically, when the pressure between egg tray layers is too large due to long-term stacking, the traditional egg tray separating mechanism is prone to the misoperation phenomenon of "multiple trays dropping simultaneously", that is, separating multiple egg trays at one time, seriously affecting the separating accuracy and equipment stability. The existing solutions usually set the stacking limit of a complete egg tray group (70 layers) to about 35 layers, reducing the single-separation pressure to reduce the error rate. To further improve the separating accuracy and production efficiency, the existing technical solutions rely on manual preprocessing. Operators need to perform the "tray loosening" operation on the stacked egg trays before the equipment runs, reducing the pressure intensity on the bottom egg trays through manual intervention, so as to create more relaxed separating conditions for the egg tray separating mechanism. Summary of the Invention

[0004] The present invention provides a poultry egg packing device, which solves the disadvantages in the prior art that in order to reduce the tightness of the bottom egg tray stacking, too many egg trays cannot be palletized at one time and manual intervention is required for tray loosening.

[0005] The present invention provides the following technical solutions:

[0006] A poultry egg packing device includes a frame body, a conveyor belt is arranged on the frame body, an egg tray feeding assembly is arranged directly above the conveyor belt, a quantitative lower egg tray assembly is arranged at the lower end of the egg tray feeding assembly, and an egg tray discharging mechanism is arranged directly below the conveyor belt;

[0007] The quantitative lower egg tray assembly includes mounting frames arranged on both sides of the egg tray feeding assembly. A pressing plate capable of horizontal movement is arranged on the mounting frames. A positioning pin is arranged on the side of the pressing plate facing the egg tray. The connecting rod on the other side of the pressing plate passes through the mounting frame and is rotatably connected to a swing rod. The lower end of the swing rod is rotatably connected to the frame body. An elastic resetting member is arranged between the pressing plate and the mounting frame. A wedge block is arranged on the side of the swing rod facing the egg tray discharging mechanism. A top rod is arranged on the egg tray discharging mechanism. The top rod cooperates with the wedge block to complete the quantitative discharging of the egg trays.

[0008] Through the cooperation of the top rod and the wedge block, the action of quantitatively discharging the egg trays can be automatically completed, and the quantitative discharging action of the egg trays can be synchronously completed without providing additional power and supporting control equipment.

[0009] As a further improvement of the above solution, a triple rotating shaft is also rotatably installed on the mounting bracket. A plurality of friction wheels are arranged on the triple rotating shaft. A one-way gear is also arranged at the end of the triple rotating shaft. Rack bars capable of vertically sliding are installed at both ends of the pressing plate. An elastic member for providing a vertical acting force is arranged between the rack bars and the pressing plate, so that the rack bars press against the one-way gear.

[0010] By providing the rotating shaft and the friction wheels, a downward frictional force can be provided to the lowermost egg tray before the positioning pin is inserted into the penultimate egg tray. Thus, even if the egg trays are pressed tightly against each other, the positioning pin can accurately insert into the penultimate egg tray, so that the egg trays pressed tightly can also be accurately separated. Therefore, there is no need for manual intervention for pre-loosening the trays, or putting them in multiple times with only a small number of egg trays stored each time, thereby improving the separation efficiency.

[0011] As a further improvement of the above solution, the egg tray feeding assembly includes a plurality of guide rods enclosing a rectangular cross-section. The guide rods are fixed to the frame body, and there is a distance between the bottom of the guide rods and the conveyor belt. The top of the guide rods is provided with a flared structure.

[0012] The guide rods enclose a rectangular cross-section to form a channel for guiding the egg trays, so that the egg trays can move neatly downward in the vertical direction, ensuring that the egg trays can be accurately separated.

[0013] The egg tray discharging mechanism includes a lifting platform capable of adjusting the height and installed on the frame body. At least one set of fixed clamping plates and one set of movable clamping plates are installed on the lifting platform. The movable clamping plate can reciprocally move towards the fixed clamping plate. The movable clamping plate and the fixed clamping plate cooperate to complete the clamping of the egg trays.

[0014] By providing the lifting platform, the fixed clamping plate and the movable clamping plate can move vertically to the lower part of the lowermost egg tray. Subsequently, the movable clamping plate and the fixed clamping plate cooperate to clamp and support the lowermost egg tray. After the positioning pin is inserted into the penultimate egg tray, the lifting platform, together with the fixed clamping plate and the movable clamping plate, drives the lowermost egg tray to move above the conveyor belt. Subsequently, the movable clamping plate and the fixed clamping plate cooperate to release the clamping of the egg tray. After the egg tray falls on the conveyor belt, it is conveyed to the next process.

[0015] As a further improvement of the above solution, a push rod is installed on the outer side of the movable clamping plate. When the movable clamping plate moves away from the fixed clamping plate, the push rod cooperates with the wedge block to push the swing rod to rotate around the ear seat at the bottom. When the movable clamping plate moves close to the fixed clamping plate, the push rod does not contact the wedge block.

[0016] By moving the movable splint closer to or farther from the fixed splint, the linear distance from the ejector rod to the wedge block can be changed. When the movable splint moves away from the fixed splint, the linear distance from the ejector rod to the wedge block becomes shorter, causing the ejector rod to contact the wedge block, which in turn causes the swing rod to rotate around the ear seat at the bottom, enabling the upper pressing plate to be pulled closer to the mounting bracket and the positioning pin to be pulled out of the original egg tray. After the ejector rod leaves the wedge block, the pressing plate moves away from the mounting bracket and the positioning pin is reinserted into the next egg tray.

[0017] As a further improvement of the above solution, guide chutes are provided on the end plates at both ends of the mounting bracket. A sliding seat is slidably connected in the guide chutes. A three-rotation is rotatably mounted on the sliding seat. An elastic member is provided between the sliding seat and the guide chutes to ensure that the three-rotation always faces the egg tray feeding assembly.

[0018] By providing the guide chutes and the sliding seat, the three-rotation shaft can slide in the guide chutes, so that when the egg tray moves downward, the friction wheel will not exert too much force on the egg tray, avoiding serious deformation of the egg tray.

[0019] As a further improvement of the above solution, two L-shaped bearing plates are further provided on the lifting platform. The L-shaped bearing plates are located on both sides of the fixed plate, and through holes for the ejector rod to pass through are provided on the L-shaped bearing plates.

[0020] The L-shaped bearing plates can guide the ejector rod, enabling the ejector rod to accurately cooperate with the wedge block.

[0021] As a further improvement of the above solution, sealing plates are provided on the front and rear sides of the fixed plate. On the top of the fixed plate and the sealing plates, side top plates and a middle top plate for supporting the egg tray are provided.

[0022] By providing the side top plates and the middle top plate, the egg tray can be supported.

[0023] As a further improvement of the above solution, an avoidance groove for avoiding the friction wheel is further provided on the pressing plate.

[0024] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0025] In the present invention, by the cooperation of the ejector rod and the wedge block, the action of automatically discharging a fixed quantity of egg trays can be completed, and the action of discharging a fixed quantity of egg trays can be synchronously completed without providing additional power and supporting control equipment.

[0026] By setting the rotating shaft and the friction wheel, it is possible to provide a downward frictional force to the lowermost egg tray before the positioning pin is inserted into the penultimate egg tray. Thus, even if the egg trays are pressed tightly together, the positioning pin can accurately insert into the penultimate egg tray, enabling precise tray separation for tightly pressed egg trays. As a result, there is no need for manual intervention to perform a pre-loosening action or to place the egg trays in multiple batches with only a small number of egg trays deposited each time, thereby improving the tray separation efficiency.

[0036] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] As Figures 1-7 shown, a pallet separating device of a poultry egg packing device includes a frame body 2. A conveyor belt 6 driven by a motor to rotate is arranged on the frame body 2. The conveyor belt 6 is used to send the egg trays into the next conveying structure. Above the conveyor belt 6, there is an egg tray loading component for storing the stacked egg trays, and at the lower end, there is a quantitative egg tray discharging component for holding the egg trays stored in the egg tray loading component and releasing one egg tray at a time. Below the conveyor belt 6, there is an egg tray unloading mechanism for receiving the released one egg tray and neatly placing it on the conveyor belt 6.

[0038] Specifically, the frame body 2 includes two crossbeams at the top. Installation holes are opened at the ends of the two crossbeams. Bearings are installed in the installation holes. A first rotating shaft 7 and a second rotating shaft 14 are rotatably installed through the bearings. Two first synchronous wheels 5 and two second synchronous wheels 15 are respectively installed on the first rotating shaft 7 and the second rotating shaft 14. The two first synchronous wheels 5 and the two second synchronous wheels 15 are drivingly connected by a synchronous belt. The synchronous belt serves as the conveyor belt 6. The spacing of the synchronous belt is adapted to the width of the egg tray, and there is a distance between the synchronous belt and the edge of the egg tray, so that when the egg tray is placed on the upper side of the synchronous belt, the synchronous belt can stably convey the egg tray.

[0039] Furthermore, for stable conveying, a support plate 13 with a smooth surface is installed between the two crossbeams. The support plate 13 is located below the upper belt body of the synchronous belt, so as to support the upper belt body of the synchronous belt. When the egg tray is conveyed on the upper side of the synchronous belt, through the support of the support plate 13, the synchronous belt can be prevented from sagging, so as to avoid displacement changes of the egg tray during the transmission on the synchronous belt, thereby improving the stability of the egg tray transmission.

[0040] Both of the two cross beams are connected with two vertical columns for supporting on the ground. An installation plate 20 at the bottom is installed between the two vertical columns. A driving motor 1 is installed on the installation plate 20. A driving wheel 41 is installed on the output shaft of the driving motor 1 by means of a spline. A driven wheel 4 is installed on a rotating shaft 7 by means of a spline. A transmission belt 3 is installed between the driving wheel 41 and the driven wheel 4. When the driving motor 1 is powered on, it can drive a rotating shaft 7 to rotate through the driving wheel 41 and the driven wheel 4, so as to drive the synchronous belt for conveying.

[0041] Specifically, both the driving wheel 41 and the driven wheel 4 are belt wheels, and the transmission belt 3 is a belt.

[0042] The egg tray loading component includes two n-shaped frames 8 fixed on the frame 2. The n-shaped frames 8 straddle the transmission belt 6 and are respectively fixedly connected with the two cross beams. The connection method can be welding or detachable installation by bolts. The two n-shaped frames 8 are arranged in parallel. Four guide rods 9 are fixed on the inner sides of the two n-shaped frames 8. The four guide rods 9 enclose a rectangle for guiding and limiting the egg tray, so that the egg tray can only move vertically within the four guide rods 9.

[0043] Specifically, the structures of the four guide rods 9 are the same, which are profiles with an L-shaped cross section. One side of the guide rod 9 is fixedly connected with the n-shaped frame 8, and the connection method is welding connection.

[0044] Furthermore, in order to conveniently place the egg tray, a flared structure 10 is arranged at the top of the guide rod 9. The flared structure 10 encloses a larger rectangular cross section, so that it is more convenient to put the egg tray from the upper part.

[0045] The quantitative egg tray component includes mounting brackets arranged on the left and right sides of the N-shaped frame 8 (with the direction of conveyor belt 6 transmission as the front side). A pressing plate 11 is mounted on the mounting bracket and is arranged facing the guide rod 9. A row of positioning pins 12 is arranged on the side of the pressing plate 11 facing the guide rod 9. Chute grooves are provided at both ends of the pressing plate 11, and the chute grooves are slidably connected to the end plates at both ends of the mounting bracket. A connecting rod is arranged on the other side of the pressing plate 11. The connecting rod penetrates through the mounting bracket and is rotatably connected to the upper end of the swing rod 16. The lower end of the swing rod 16 is rotatably connected to the frame body 2. A spring 31 is arranged between the pressing plate 11 and the mounting bracket. A wedge-shaped block 17 is arranged on the inner side of the swing rod 16. A ejector rod 18 is arranged on the egg tray blanking mechanism and is matched with it. When the egg tray blanking mechanism moves upward, through the cooperation of the ejector rod 18 and the wedge-shaped block 17, the upper end of the swing rod 16 swings outward. At this time, a spring 31 is compressed, the pressing plate 11 approaches the mounting bracket, and the positioning pins 12 are removed from the lower egg tray. The dropped egg tray is received by the lower egg tray blanking mechanism. When the ejector rod 18 moves to the end of the wedge-shaped block 17, no force is applied to the wedge-shaped block 17. At this time, after no external force is applied to the swing rod 16, the pressing plate 11 resets under the action of a spring 31. The pressing plate 11 quickly moves toward the guide rod 9 side, and the positioning pins 12 re-insert into the next egg tray to complete positioning.

[0046] The lower end of the swing rod 16 is rotatably connected to the frame body 2. Specifically, ear plates 43 are arranged on both sides of the frame body 2. Ear seats are arranged on the ear plates 43, and the ear seats are rotatably connected to the swing rod 16 through a pin shaft.

[0047] Furthermore, in order to enable the pressed egg tray to be discharged smoothly, three rotating shafts 40 are also mounted on the mounting bracket. A plurality of friction wheels 30 are arranged on the three rotating shafts 40. A one-way gear 33 is arranged at one end of the three rotating shafts 40. Vertically slidable racks 32 are mounted at both ends of the pressing plate 11, and a spring 37 provides a force toward the one-way gear 33 direction for the racks 32. The racks 32 are engaged with the one-way gear 33. When the pressing plate 11 moves toward the guide rod 9 direction, the racks 32 drive the one-way gear 33 to rotate. At this time, the three rotating shafts 40 rotate, and the friction wheels 30 on the three rotating shafts 40 rotate together. The friction wheels 30 contact the side of the egg tray, and the side of the friction wheel 30 in contact with the egg tray rotates downward. The middle part of the egg tray is supported by the egg tray blanking mechanism, so that the two sides of the lowermost egg tray rotate slightly downward under the action of the friction wheels 30, so that the lowermost egg tray can be separated from the second-lowermost egg tray. Subsequently, the pressing plate 11 carrying the positioning pins 12 can accurately insert into the side of the second-lowermost egg tray.

[0048] Specifically, vertical through grooves are provided at both ends of the pressing plate 11. A vertical rod 38 is slidably connected in the through grooves. A rack 32 is fixed to the bottom of the vertical rod 38. A bent section is provided at the top of the vertical rod 38 so that the vertical rod 38 will not be disengaged from the through grooves. A four-spring 37 is provided between the bent section at the top of the vertical rod 38 and the pressing plate 11. The four-spring 37 is in a stretched state, thereby providing a downward acting force on the vertical rod 38.

[0049] Further, in order to prevent the three-rotating shaft 40 and the friction wheel 30 from interfering with the downward movement of the egg tray when the egg tray blanking mechanism clamps the lowermost egg tray and moves it downward, horizontal guiding chutes 35 facing the n-shaped frame 8 are provided on the end plates at both ends of the mounting frame. A sliding seat 34 is slidably connected in the guiding chutes 35. A two-spring is provided between the sliding seat 34 and the end (the end far from the n-shaped frame 8) of the guiding chutes 35 so that when the egg tray blanking mechanism clamps the lowermost egg tray and moves it downward, the three-rotating shaft 40 and the friction wheel 30 will compress the three-spring 36 after being acted upon, thereby reducing the influence on the egg tray.

[0050] The sliding seat 34 is provided with a through hole for the three-rotating shaft 40 to pass through. The sliding seat 34 is slidably connected to the guiding chutes 35. In order to limit the sliding seat 34, a border is provided on the side of the sliding seat 34 away from the one-way gear 33. The border is located on the upper and lower sides of the sliding seat 34 and extends out of the guiding chutes 35. The sliding seat 34 is prevented from displacing in the direction perpendicular to the guiding chutes 35 through the border.

[0051] The egg tray blanking mechanism includes a vertically liftable lifting platform 19. Two parallel fixing plates 29 are installed on the upper part of the lifting platform 19. Two parallel sliding rods 28 are provided between the fixing plates 29. Two fixed clamping plates 26 are fixedly installed in the middle of the sliding rods 28. Two sliding clamping plates 25 are provided outside the two fixed clamping plates 26. A double-headed bidirectional cylinder 22 is installed on the lifting platform 19. The two output ends of the double-headed bidirectional cylinder 22 are respectively connected to a sliding clamping plate 25. When the egg tray blanking mechanism moves below the egg tray, the two fixed clamping plates 26 are attached to the protrusions at the lower part of the egg tray. At this time, the distance between the sliding clamping plate 25 and the fixed clamping plate 26 is slightly wider than the protruding platform at the lower part of the egg tray. The double-headed bidirectional cylinder 22 works, thereby driving the sliding clamping plate 25 to move along the sliding rod 28 towards the fixed clamping plate 26 until the sliding clamping plate 25 and the fixed clamping plate 26 cooperate to complete the clamping action on the egg tray. A top rod 18 is provided outside the sliding clamping plate 25. The top rod 18 is used to cooperate with the wedge block 17 to drive the swing rod 16 to swing.

[0052] Further, in order to improve the clamping stability, two L-shaped bearing plates 23 are also provided on the lifting platform 19. The L-shaped bearing plates 23 are located on both sides of the fixing plates 29 and are used to support the egg tray. Through holes for the top rod 18 to pass through are provided on the L-shaped bearing plates 23, so as to be able to guide the top rod 18 and make the top rod 18 always face the wedge block 17 directly.

[0053] Further, sealing plates are arranged on the front and rear sides of the fixing plate 29. On the top of the fixing plate 29 and the sealing plates, two side top plates 24 and a middle top plate 27 are provided. A space for the sliding clamping plate 25 and the fixed clamping plate 26 to move is left between the middle top plate 27 and the side top plates.

[0054] Specifically, a functional cylinder 21 is installed at the lower part of the mounting plate 20. The output shaft of the functional cylinder 21 passes through the mounting plate 20 and is fixedly connected to the lower side of the lifting platform 19. By extending or retracting the output shaft of the functional cylinder 21, the lifting platform 19 is vertically lifted or lowered.

[0055] Further, to improve the stability of the lifting platform 19, four guide sleeves are installed on the mounting plate 20. Guide rails 42 pass through the guide sleeves, and the upper ends of the guide rails 42 are fixedly connected to the lower side of the lifting platform 19.

[0056] Further, an avoidance groove 39 for avoiding the friction wheel 30 is also provided on the pressing plate 11, so that when the pressing plate 11 moves towards the guide rail 42, the pressing plate 11 will not interfere with the friction wheel 30.

[0057] Working principle:

[0058] The egg trays stacked together are placed between the four guide rails. The bottom egg tray is caught by the positioning pins 12 and will not fall. Subsequently, the lifting platform 19 is driven to move upward;

[0059] At this time, the sliding clamping plate 25 moves away from the fixed clamping plate 26. The ejector rod 18 on one side of the sliding clamping plate 25 moves upward with the lifting platform 19. During the movement, the ejector rod 18 contacts the inclined surface of the wedge block 17, and the ejector rod 18 pushes the swing rod 16 to rotate outward (away from the frame body 2). The top of the swing rod 16 pulls the pressing plate 11 to move towards the mounting frame side (away from the guide rod 9 side). At this time, the rack 32 and the one-way gear 33 slide relative to each other, and the one-way gear 33 does not rotate;

[0060] When the sliding clamping plate 25 and the fixed clamping plate 26 move to the lowest egg tray, the positioning pins 12 are completely separated from the egg tray. The egg tray moves downward and is supported by the sliding clamping plate 25 and the fixed clamping plate 26. And at this time, the ejector rod 18 is separated from the wedge block 17;

[0061] After no external force acts on the swing rod 16, the pressing plate 11 moves away from the mounting frame towards the guide rod 9 side under the action of a spring 31. During the movement, the pressing plate 11 drives the rack 32 to move towards the guide rail direction. At this time, the rack 32 meshes with the one-way gear 33, driving the one-way gear 33 to rotate. The one-way gear 33 drives the friction wheel 30 to rotate. The friction wheel 30 provides a downward frictional force on both sides (the side close to the mounting frame) of the lowermost egg tray, so that the lowermost egg tray is separated from the second-lowermost egg tray. Subsequently, the positioning pins 12 are inserted into the second-lowermost egg tray;

[0062] Subsequently, the double-headed bidirectional cylinder 22 drives the sliding clamping plate 25 to move towards the fixed clamping plate 26, thereby completing the clamping of the egg tray. And because the sliding clamping plate 25 moves inwards, the distance between the ejector rod 18 and the wedge block 17 changes, so that during the downward movement of the moving platform, the ejector rod 18 will not contact the wedge block 17;

[0063] Subsequently, the moving platform is driven to move downwards. During the downward movement of the egg tray, the triple-rotating shaft 40 is squeezed, so that the triple-rotating shaft 40 moves along the guiding chute 35, thereby avoiding serious deformation of the egg tray. When the egg tray moves above the conveyor belt, the sliding clamping plate 25 is driven by the double-headed bidirectional cylinder 22 to move away from the fixed clamping plate 26, thereby releasing the egg tray. Finally, the egg tray falls on the conveyor belt, and the conveyor belt sends the egg tray to the next process;

[0064] Repeat the above process, so as to continuously and automatically provide egg trays.

[0065] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
