[0001] This utility model relates to an egg tray separation mechanism for a paisley tray machine. Background Technology

[0002] To reduce the breakage rate of poultry eggs during transportation and storage, egg trays are commonly used for packaging and transport. In the mechanized packaging of poultry eggs, tray-dispensing equipment is often used to transport empty trays to the filling station. However, in some tray-dispensing machines, stacked trays are manually separated one by one before being placed on a chain conveyor to transport them to the filling station, as illustrated by a semi-automatic tray-dispensing machine disclosed in Chinese Patent Publication No. CN105691741B. However, this manual tray-separation method is not only inefficient but also wastes human resources. Therefore, improving the tray-separation efficiency and reducing manual labor is a pressing technical problem, leading to this case. Utility Model Content

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figures 1-10As shown, this utility model discloses an egg tray separation mechanism for a paisley tray machine, applicable to plastic egg trays 5. The plastic egg tray has multiple egg slots 51 arranged in a matrix, and the upper end of the egg tray has a ring-shaped edge 52. It includes an egg tray support frame and a liftable gripping component 401 located below the egg tray support frame 2. Multiple egg trays are stacked vertically in the egg tray support frame. The liftable gripping component 401 has a pair of hooks 402 located on the left and right sides below the egg tray support frame and a drive shaft 403 for driving the hooks 402 to flip upward and hook the hollow part on the lower periphery of the egg tray. Each hook 402 is driven to flip upward by a drive shaft 403. The drive shaft 403 is installed longitudinally on a lifting seat 404. The lifting seat drives the drive shaft and hooks to move up and down vertically synchronously. During operation, multiple egg trays are stacked vertically within the egg tray holder. The lifting platform moves the drive shaft and hook upwards. The hook then flips upwards and hooks onto the lower periphery of the bottommost egg tray. Figure 12 As shown; then the lifting seat moves the lowest egg tray downwards via the hook, separating the egg tray, as shown. Figure 13 As shown.

[0034] In this embodiment, the egg tray holder has egg tray clamps at both ends for holding stacked egg trays from the left and right sides. The egg tray clamps at both ends of the egg tray holder can move from left to right or back to back to clamp or release the egg trays.

[0035] In this embodiment, a conveyor belt for receiving egg trays is provided between the drive shafts 403 of the two side hooks 402. The conveying direction of the conveyor belt is parallel to the drive shafts 403, and the conveyor belt is used to transport the egg trays from back to front. Further, the conveyor belt is a pair of circular belts 405 distributed to the left and right. During operation, the egg trays, separated downwards by the hooks, fall onto the pair of conveyor belts, as... Figure 14 As shown, the circular belts are located in the grooves between two adjacent rows of egg slots at the bottom of the egg tray. A pair of circular belts support the egg tray and transport it, and finally the hooks return to their original position.

[0036] In this embodiment, the hook 402 includes several pairs of rotating hooks 406 that are spaced apart along the axial direction of the drive shaft. The hook portion of the rotating hook 406 is provided with three protruding pins 407 for inserting into the hollowed-out portion around the egg tray. The end of the rotating hook 406 away from the hook portion is provided with a connecting sleeve 408 for fitting onto the outside of the drive shaft 403.

[0037] In this embodiment, a scale plate 409 is arranged parallel to the lower part of the drive shaft 403, and the scale lines 410 on the surface of the scale plate 409 extend along the axial direction of the drive shaft. By providing a scale plate below the drive shaft, it is convenient to adjust the position of the flip hooks along the axial direction of the drive shaft, and to easily control the spacing between the flip hooks.

[0038] In this embodiment, the inner sidewall of the connecting sleeve 408 is provided with a sliding protrusion 411; the outer peripheral side of the drive shaft 403 is provided with a groove that cooperates with the sliding protrusion 411. When the connecting sleeve is sleeved on the outside of the drive shaft, by setting the sliding protrusion and the groove, it is convenient for the connecting sleeve to slide along the drive shaft, and it can also prevent the connecting sleeve and the drive shaft from rotating relative to each other.

[0039] In this embodiment, to facilitate the fixing of the connecting sleeve, a row of axially extending locking grooves 413 is provided on the outer peripheral side of the drive shaft 403. In each pair of flip hooks, a connecting plate 414 is fixed between the connecting sleeves 40 of the two flip hooks 406. One of the flip hooks 406 has an extended cantilever 415 on the end face of its connecting sleeve. The side of the extended cantilever 415 facing the axis of the connecting sleeve 408 is provided with several locking protrusions 416 for engaging in the locking grooves 413. By using the locking protrusions to engage in the locking grooves, the connecting sleeve is limited, preventing the connecting sleeve from moving axially along the drive shaft.

[0040] In this embodiment, to facilitate the movement of the connecting sleeve, a lever 417 is provided on the side of the extended cantilever 415 facing away from the axis of the connecting sleeve 408 for turning the extended cantilever 415. During operation, the extended cantilever is turned by the lever, causing the locking protrusion and locking groove to separate. At this time, the connecting sleeve can be moved along the axial direction of the drive shaft, thereby adjusting the position of the flip hook.

[0041] In this embodiment, a drive rocker arm 418 is fixed to the outer peripheral side of the rear end of the drive shaft 403. The drive rocker arm is arranged radially along the drive shaft. The end of the drive rocker arm 418 away from the drive shaft 403 is hinged to a pull rod 419. The pull rod 419 is driven to move up and down by a drive component. When the pull rod 419 moves up and down, it drives the drive shaft 403 to rotate through the drive rocker arm 418. The rotation of the drive shaft causes the hook to flip up and down. Specifically: when the pull rod moves down, the drive rocker arm drives the longitudinal shaft to rotate, and the longitudinal shaft drives the hook to swing upward to hook the egg tray; when the pull rod moves up, the drive rocker arm drives the longitudinal shaft to rotate in the opposite direction, and the longitudinal shaft drives the hook to swing downward to separate the hook from the egg tray. It should be noted that the function of the drive component here is simply to drive the pull rod to move up and down. For example, it can be a cam transmission mechanism, or a cylinder, hydraulic cylinder, electric push rod, or other structure that can achieve linear reciprocating motion, which can be selected as needed.

[0042] In this embodiment, the lifting seat 404 is driven to rise and fall by the lifting rod 420 vertically arranged below it. The lifting rod can be driven to move up and down by the lifting drive component. The lifting drive component can be a cam transmission mechanism, or a cylinder, hydraulic cylinder, electric push rod or other structure that can realize linear reciprocating motion, etc., which can be selected as needed.

[0043] In this embodiment, the lifting seat is U-shaped, and the drive shafts of the left and right hooks are installed on the top of both sides of the lifting seat.

[0044] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0045] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0046] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
