Description

Technical Field

[0001] The invention relates to a device for adjusting the left-right displacement of an egg clamp for an egg packaging line and a working method thereof. Background Art

[0002] When collecting and packaging eggs, it is generally necessary to place multiple eggs that are synchronously grabbed in rows on an egg tray conveyed by an egg packaging line through multiple egg clamp assemblies. A conventional egg tray has several rows of egg placement slot groups, and the number of egg placement slots in each row is the same and all are aligned. For example, there are 7 rows of egg placement slot groups on the egg tray, and each row of egg placement slot groups has 6 egg placement slots, then the 6 adjacent egg placement slots in each row are all aligned. Since the egg placement slots in each row are the same, as the egg tray moves, the existing egg clamp assembly can accurately place the 6 grabbed eggs in the egg placement slots in each row.

[0003] In order to adapt to different needs, such as Fig.18 As shown, when a special-shaped egg tray is used to place eggs, since the egg placement slots in adjacent rows on the egg tray are staggered, the conventional egg clamp assembly cannot accurately place the eggs in the egg placement slots of the special-shaped egg tray, thereby affecting the egg packaging work.

The opening and closing actuator includes a synchronous driving rod that is horizontally arranged symmetrically on the left and right. An arc-shaped sleeve that cooperates with the synchronous driving rod on the same side is arranged on the lower surface of the flat plate portion of each clamping jaw on the same side. The opening and closing driving mechanism is installed between one ends of the two synchronous driving rods. The two synchronous driving rods are located at one end of the opening and closing driving mechanism and are both equipped with a swinging assembly that drives the synchronous driving rod to rotate around a horizontal rotating rod. The opening and closing driving mechanism drives the swinging assembly to move.

[0011] Furthermore, the swing assembly includes a driving rotating sleeve, a first connecting rod and a second connecting rod are connected to the outer periphery of the driving rotating sleeve, a mounting sleeve is provided on the other end of the first connecting rod, the driving rotating sleeve is mounted on the positioning rod, and the mounting sleeve is fixed to the corresponding synchronous driving rod.

[0012] Furthermore, the opening and closing drive mechanism includes an opening and closing drive motor, which is installed on one side of the egg clamp bracket.

[0013] Furthermore, the upper parts of the two egg clamp brackets are connected via a bracket connecting rod, and the lower parts of the two egg clamp brackets are connected via a synchronous lifting rod. The synchronous lifting rod transversely penetrates the egg conveying production line, and a yield groove is provided at the lifting track position of the synchronous lifting rod on the egg conveying production line.

[0014] Furthermore, both sides of the egg conveying production line are rotatably connected with synchronously rotating swing arms, the ends of the swing arms are hinged to the lower part of the egg clamp bracket on the same side, and both sides of the egg conveying production line are rotatably connected with synchronously rotating auxiliary swing rods, the ends of the auxiliary swing rods are hinged to the middle part of the egg clamp bracket on the same side; a driving arm is coaxially installed with the swing arm on one side of the egg conveying production line, the angle between the driving arm and the swing arm is fixed, a groove plate driven to rotate by a motor is installed on the side of the egg conveying production line, the groove plate is provided with a spiral groove, and a driving roller matching the spiral groove is installed on the end of the driving arm.

[0015] Furthermore, the working method of the left-right shift adjustment device for the egg clamp unloading of the egg packaging line comprises the following steps: (1) the egg conveying production line drives the special-shaped egg tray to move forward to the bottom of the egg clamp mechanism of the egg clamp lateral shift positioning rod assembly, and the A'-arranged egg tray slot of the special-shaped egg tray is located below the egg clamp mechanism; (2) the upper swing body on the left side rotates so that the double-stage driving inclined surface A of the upper swing body cooperates with the roller of the egg clamp lateral shift driving rocker arm on the left side, and the upper swing body on the right side rotates so that the double-stage driving inclined surface B cooperates with the egg clamp lateral shift driving rocker arm on the right side. The roller of the shift driving rocker arm cooperates with each other; (3) the egg clamp lateral shift positioning rod assembly descends, and the egg clamp lateral shift driving rockers on both sides move along the double-step driving inclined planes A and B respectively, and the driving rockers realize the inward displacement of each egg clamp assembly along the positioning rod through the driving rod sleeve. Since the displacement of the egg clamp lateral shift driving rocker arm on the left side is larger, each egg clamp assembly is shifted to the right side, so that each egg clamp assembly of the egg clamp mechanism is aligned with the egg tray arranged A', and the egg clamp assembly is opened to put the eggs into the egg tray arranged A'; (4) The egg clamp lateral shift positioning rod assembly rises and resets, and the egg clamp lateral shift driving rocker arms on both sides are reset accordingly, and the egg conveying production line drives the special-shaped egg tray to move forward one station, so that the B' arrangement egg tray slot of the special-shaped egg tray is located below the egg clamp mechanism; (5) The upper swing body on the left rotates so that the double-step driving inclined surface B of the swing body cooperates with the roller of the egg clamp lateral shift driving rocker arm on the left, and the upper swing body on the right rotates so that the double-step driving inclined surface A cooperates with the roller of the egg clamp lateral shift driving rocker arm on the right; (6) ... The positioning rod assembly is lowered, and the egg clamps on both sides are laterally displaced and driven by the rocker arms to move along the double-step driving inclined surfaces B and A respectively. The driving rocker arms realize the inward displacement of each egg clamp assembly along the positioning rod through the driving rod sleeve. Since the displacement of the lateral displacement driving rocker arm of the egg clamp on the right side is larger, each egg clamp assembly is displaced to the left side, so that each egg clamp assembly of the egg clamp mechanism is aligned with the second row of egg tray placement slots. The egg clamp assembly is opened to place the eggs into the B'-arranged egg tray slots; (7) the above steps are repeated until the eggs are filled with the special-shaped egg trays.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the device has a simple structure, a reasonable design, and is easy to use. When the egg conveying production line drives the A'-arranged egg tray slot of the special-shaped egg tray to move to the bottom of the egg clamp mechanism, the lower rocker arm located on the left side drives the upper swing body on the left side to swing, so that the double-stage driving inclined surface A of the upper swing body on the left side cooperates with the roller of the egg clamp lateral displacement driving rocker arm to work, and the lower rocker arm located on the right side drives the upper swing body on the right side to swing, so that the double-stage driving inclined surface B of the upper swing body on the right side cooperates with the roller of the egg clamp lateral displacement driving rocker arm to work, when the egg clamp assembly moves downward , the rollers of the lateral shift driving rocker arms of the egg clamps on both sides drop synchronously and cooperate with each other on the driving inclined planes of different stations. Since the width of the double-stage driving inclined plane A is greater than that of the double-stage driving inclined plane B, the upper part of the lateral shift driving rocker arm of the egg clamp on the left side moves along the positioning rod with a larger offset. The lateral shift driving rocker arm of the egg clamp on the left side pushes the driving rod sleeve on the left side to move more along the positioning rod. Under the cooperation of the spring elastic force between the egg clamp assemblies, the egg clamp assemblies are translated to the right as a whole, so that the egg clamp assemblies are aligned with the egg tray arranged in A', and the egg clamp assemblies are opened to make the eggs fall. In the A' arranged egg tray; similarly, when the A' arranged egg tray of the special-shaped egg tray is loaded with eggs, the egg conveying production line continues to drive the special-shaped egg tray to advance one station, so that the B' arranged egg tray moves to the bottom of the egg clamp mechanism, and the lower rocker arm on the left drives the upper swing body on the left to swing, so that the double-stage driving inclined surface B of the upper swing body on the left cooperates with the roller of the egg clamp lateral displacement driving rocker arm, and the lower rocker arm on the right drives the upper swing body on the right to swing, so that the double-stage driving inclined surface A of the upper swing body on the right cooperates with the roller of the egg clamp lateral displacement driving rocker arm, when the egg clamp assembly moves downward The rollers of the lateral shift driving rocker arms of the egg clamps on both sides are synchronously lowered and work on the driving inclined planes of different stations respectively. Since the width of the double-stage driving inclined plane B is smaller than that of the double-stage driving inclined plane A, the upper part of the lateral shift driving rocker arm of the egg clamp on the right side rotates with a larger offset relative to the hinge point. The lateral shift driving rocker arm of the egg clamp on the right side pushes the driving rod sleeve on the right side to move more along the positioning rod, so that each egg clamp assembly is translated to the left as a whole. At this time, the egg clamp assembly is aligned with the B' arranged egg tray slot, the egg clamp assembly is opened, and the eggs of the egg clamp assembly are placed in the B' arranged egg tray slot. The rows of egg tray placement slots of the special-shaped egg tray are offset and placed repeatedly through the above working process.

[0017] The device is provided with two rotatable upper swing bodies on both sides of the egg conveying production line. When the roller of the lateral displacement driving rocker arm of the egg clamp on one side cooperates with the double-step driving inclined plane A, the roller of the lateral displacement driving rocker arm of the egg clamp on the other side cooperates with the double-step driving inclined plane B. The lower part of the upper swing body is hinged on the corresponding side of the egg conveying production line. The egg production line is provided with a lower swing arm for driving the upper swing body to swing. When the lower swing arms on both sides swing synchronously back and forth, the rollers of the driving rockers on both sides can work on the driving inclined planes of different stations. The egg clamp on the lateral displacement positioning rod assembly is shifted left and right relative to the positioning rod through the driving rod sleeve, and the egg clamp assembly is driven to shift along the positioning rod as a whole, thereby realizing accurate egg delivery in the egg placement grooves of the rows of misaligned egg trays, and ensuring the egg packaging work of placing the eggs on the special-shaped egg trays.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example: Figures 1 to 18As shown, in this embodiment, an egg clamp unloading left and right shift adjustment device for an egg packaging line and a working method thereof are provided, including an egg conveying production line 100 for conveying egg trays, egg clamp brackets 200 that can be raised and lowered synchronously are arranged on both sides of the egg conveying production line, egg clamp lateral shift positioning rod assemblies 300 are arranged on the egg clamp brackets, and egg clamp lateral shift driving rocker arms 101 are respectively arranged on the two outer sides of the egg clamp brackets, the upper end of the egg clamp lateral shift driving rocker arm is hinged to a driving rod sleeve 103 sleeved on the end of the egg clamp lateral shift positioning rod assembly through a linkage short rod 102, and a roller 104 is hinged to the lower end of the egg clamp lateral shift driving rocker arm, and the inner end of the driving rod sleeve is hinged to a spring 304 arranged between two adjacent clamping claw rotating sleeves through a clamping claw rotating sleeve 304 on the egg clamp lateral shift positioning rod assembly. 5 elastic contact, so that the roller keeps in contact with the double-step driving inclined planes A and B. When the roller is lifted and lowered with the egg clamp bracket, it can cooperate with the upper swing body 105 with the double-step driving inclined planes A and B respectively fixed on the two side surfaces of the production line. When the roller of the egg clamp lateral displacement driving rocker on one side cooperates with the double-step driving inclined plane A, the roller of the egg clamp lateral displacement driving rocker on the other side cooperates with the double-step driving inclined plane B. The lower part of the upper swing body 105 is hinged on the corresponding side of the egg conveying production line. The egg production line is provided with a lower swing arm 106 for driving the upper swing body to swing. When the lower swing arms on both sides swing synchronously back and forth, the rollers of the driving rockers on both sides can work on the driving inclined planes of different stations, and the egg clamp on the egg clamp lateral displacement positioning rod assembly is shifted left and right relative to the positioning rod 301 through the driving rod sleeve.

[0022] The width of the above-mentioned double-step drive slope A is greater than that of the double-step drive slope B, that is, the double-step drive slope A is located outside the double-step drive slope B; due to the different widths of the double-step drive slope A and the double-step drive slope B, the deflection angles of the lateral displacement driving rocker arms of the egg clamps on both sides are different. The deflection angle of the lateral displacement driving rocker arm of the egg clamp on one side will be larger, and the deflection angle of the lateral displacement driving rocker arm of the egg clamp on the other side will be smaller, thereby realizing the control of the spring compression amount between the egg clamp components of the egg clamp mechanism.

[0023] During operation: the egg conveying production line drives the A'-arranged egg tray of the special-shaped egg tray to move under the egg clamp mechanism. The lower rocker arm located on the left side drives the upper swing body on the left side to swing, so that the double-stage driving inclined surface A of the upper swing body on the left side cooperates with the roller of the egg clamp transverse displacement driving rocker arm; the lower rocker arm located on the right side drives the upper swing body on the right side to swing, so that the double-stage driving inclined surface B of the upper swing body on the right side cooperates with the roller of the egg clamp transverse displacement driving rocker arm; when the egg clamp assembly moves downward, the rollers of the egg clamp transverse displacement driving rocker arms on both sides descend synchronously and work on the driving inclined surfaces of different stations respectively; since the width of the double-stage driving inclined surface A is greater than the double-stage driving inclined surface B, at this time, the offset amount of the upper part of the egg clamp transverse displacement driving rocker arm on the left side rotating along the hinge point is larger, and the egg clamp transverse displacement driving rocker arm on the left side pushes the driving rod sleeve on the left side to move along the positioning rod to move a larger displacement, so that each egg clamp assembly is translated to the right as a whole, so that the egg clamp assembly is aligned with the egg tray arranged in A', and the eggs of the egg clamp assembly are placed in the egg tray arranged in A'; When the A' arrangement egg tray of the special-shaped egg tray is loaded with eggs, the egg conveying production line continues to drive the special-shaped egg tray forward one station, so that the B' arrangement egg tray moves to the bottom of the egg clamp mechanism, and the lower rocker arm on the left drives the upper swing body on the left to swing, so that the double-stage driving inclined surface B of the upper swing body on the left cooperates with the roller of the egg clamp lateral displacement driving rocker arm, and the lower rocker arm on the right drives the upper swing body on the right to swing, so that the double-stage driving inclined surface A of the upper swing body on the right cooperates with the roller of the egg clamp lateral displacement driving rocker arm. When the egg clamp assembly moves downward, The rollers of the lateral shift driving rocker arms of the egg clamps on both sides descend synchronously and work on the driving inclined planes at different stations respectively. Since the width of the double-stage driving inclined plane B is smaller than that of the double-stage driving inclined plane A, the offset of the upper part of the lateral shift driving rocker arm of the egg clamp on the right side relative to the hinge point is larger at this time, and the lateral shift driving rocker arm of the egg clamp on the right side pushes the driving rod sleeve on the right side to move a larger displacement along the positioning rod, so that each egg clamp assembly is translated to the left as a whole. At this time, the egg clamp assembly is aligned with the B'-arranged egg tray, and the eggs of the egg clamp assembly are placed in the B'-arranged egg tray.

[0024] The A'-arranged egg tray slots and the B'-arranged egg tray slots of the special-shaped egg tray are moved forward in turn to place eggs until the special-shaped egg tray is full of eggs.

[0025] It is worth explaining here that when the roller of the egg clamp lateral shift driving rocker arm on one side is on the double-step driving inclined plane A and the roller of the egg clamp lateral shift driving rocker arm on the other side is on the double-step driving inclined plane B, the displacement of the driving rod sleeve pushed by the egg clamp lateral shift driving rocker arm whose roller is on the double-step driving inclined plane A is greater than that of the egg clamp lateral shift driving rocker arm whose roller is on the double-step driving inclined plane B on the other side, thereby achieving that the driving rod sleeve on one side compresses the egg clamp assembly a little more, and the driving rod sleeve on the other side compresses the egg assembly a little less, and under the action of the spring force, the adjacent egg clamp assemblies move and adjust to the corresponding positions.

[0026] When the egg clamp drives the rocker arm to shift laterally as the egg clamp mechanism rises, each egg clamp assembly is reset under the action of the spring elastic force between the egg clamp assemblies; when the egg clamp drives the rocker arm to shift laterally as the egg clamp mechanism descends, the egg clamp assemblies on both sides are pressed and deflected inwardly, with a larger spring compression on one side and a smaller spring compression on the other side. When both sides have completed the shift, the side with a larger spring compression will deflect toward the side with a smaller spring compression, and the springs between the egg clamp assemblies will automatically adjust to be uniform.

[0027] In the initial state, the width of the egg clamp mechanism is greater than the width of the egg tray. When the egg clamp mechanism moves downward, the egg clamp components are squeezed, and the distance between adjacent egg clamp components is aligned with the egg placement slot of the egg tray.

[0028] In the embodiment of the present invention, the lower swing arm is a cylinder 107, and a cylinder swing block 108 is provided at the output end of the cylinder, and the cylinder swing block is connected to the upper swing body via a connector 109; the upper swing body is hinged to the egg conveying production line via an upper swing shaft, the upper end of the connector is connected to the upper swing shaft, the lower end of the connector is hinged to the cylinder swing block, and the non-telescopic end of the cylinder is connected to the egg conveying production line via a cylinder seat 110, the cylinder seat is hinged to the cylinder, and the cylinder seat is fixed to the egg conveying production line.

Each egg clamp assembly includes symmetrically arranged jaws 303, and the two jaws of the same egg clamp assembly are respectively arranged on the two positioning rods 301. The jaws include a clamping portion and a flat plate portion that are connected to each other, and a jaw rotating sleeve 304 is installed at the connection between the clamping portion and the flat plate portion. The jaw rotating sleeve is sleeved on the positioning rod, that is, the jaw rotating sleeve is sequentially sleeved on the positioning rod, and the rotation of the flat plate portion drives the jaw rotating sleeve to rotate, thereby realizing the opening or closing of the clamping portions of the two jaws of the same egg clamp assembly.

[0030] In an embodiment of the present invention, two adjacent jaw rotating sleeves on the same side are connected by a spring 305, and the spring sleeve is arranged on the positioning rod, that is, the jaws on the same positioning rod are connected by a spring, and the spacing between the jaws on the same positioning rod is changed by squeezing or relaxing the outermost jaw rotating sleeves at both ends of the same horizontal rotating rod.

[0031] In the embodiment of the present invention, the egg clamp lateral displacement driving rocker arm 101 includes two swing pressure rods 112 and an extension rod 113. The upper ends of the two swing pressure rods are respectively connected to the driving rod sleeves on the two positioning rods via a linkage short rod. The lower ends of the two swing pressure rods are hinged to the egg clamp bracket via a connecting shaft 111. The extension rod is arranged under one of the swing pressure rods, and the roller 104 is arranged on the extension rod.

[0032] The two swinging pressure rods on the same side end rotate synchronously. As long as one of them rotates, the other rotates synchronously. The axis of the swinging pressure rod is horizontal and perpendicular to the axis of the horizontal rotating rod, that is, the movement surface of the swinging pressure rod is on the vertical plane where the axis of the positioning rod is located; A driving rod sleeve is hinged on one end of the swing pressure rod via a linkage short rod, and the driving rod sleeve is slidably connected to the end of the positioning rod, and the end of the driving rod sleeve abuts against the end of the outermost clamping claw rotating sleeve. The swing pressure rod is hinged at one end of the linkage short rod, and the other end of the linkage short rod is hinged to the outer wall of the driving rod sleeve. The linkage short rod is driven to move by the swing pressure rod, thereby driving the driving rod sleeve to slide, thereby compressing and shifting the clamping claw.

[0033] In the embodiment of the present invention, the egg clamp assembly 302 is driven to open and close synchronously by the opening and closing assembly 400, and the opening and closing assembly includes an opening and closing driving mechanism and an opening and closing actuator. The opening and closing actuator includes a synchronous driving rod 401 that is horizontally arranged symmetrically on both sides, and an arc-shaped clamping sleeve 403 that cooperates with the synchronous driving rod on the same side is arranged on the lower surface of the flat plate portion of each clamping jaw on the same side, that is, the horizontal portion of the clamping jaw on the same positioning rod is provided with an arc-shaped clamping sleeve 403, and the arc-shaped clamping sleeve of the clamping jaw on the same horizontal rotating rod is fixed on the same synchronous driving rod, and the swinging of the clamping jaw is realized by driving the movement of the synchronous driving rod; The opening and closing driving mechanism is installed between one ends of two synchronous driving rods. The two synchronous driving rods are located at one end of the opening and closing driving mechanism and are both equipped with a swing assembly that drives the synchronous driving rod to rotate around the horizontal rotating rod. The opening and closing driving mechanism drives the swing assembly to move. The swing assembly includes a driving rotating sleeve 404, and the outer periphery of the driving rotating sleeve is connected to a first connecting rod 405 and a second connecting rod 406. The other end of the first connecting rod is provided with a mounting sleeve 407. The driving rotating sleeve 404 is sleeved on the positioning rod, and the mounting sleeve is fixed on the corresponding synchronous driving rod. When in use, the driving rotating sleeve is driven to rotate by the movement of the second connecting rod, and then the mounting sleeve is driven to rotate around the positioning rod, so that the synchronous driving rod rotates around the positioning rod, and then the movement of the clamping claw plate portion is driven to realize the opening and closing of the egg clamp assembly.

[0034] In the embodiment of the present invention, the opening and closing driving mechanism includes an opening and closing driving motor 408, which is installed on one side of the egg clamp support, and a rotating disk 409 that rotates synchronously with the rotating disk is installed on the rotating shaft of the opening and closing driving motor, and a slider 410 is installed on the end of the second connecting rod, and an arc-shaped guide slot 402 that cooperates with the left and right sliders is opened on the rotating disk. When in use, the rotation of the rotating disk drives the rotation of the arc-shaped guide slot, and then drives the slider to slide in the arc-shaped guide slot, so that the ends of the two second connecting rods are brought together or separated, and finally the egg clamp assembly is opened and closed; the driving rotating sleeve is located at the outermost end of the horizontal rotating rod, and the outermost limit position of the driving rod sleeve is limited to prevent the driving rod sleeve from coming out.
