Description

Technical Field

[0001] This utility model relates to a device for detecting and distributing missed eggs in egg trays. Background Technology

[0002] In the egg production and packaging process, eggs from egg trays delivered by farms need to be removed for subsequent cleaning and other processes, and empty egg trays need to be collected. Existing egg-collecting mechanisms typically use suction cups, which occasionally miss eggs during operation. If egg trays carrying missed eggs are output along with empty trays, it will damage the eggs and also affect the collection of empty trays. Therefore, an egg tray egg-missing detection and distribution device is needed. Utility Model Content

[0003] The purpose of this invention is to provide an egg tray egg product missing detection and distribution device. This device is convenient for detecting whether there are missing eggs on the egg tray and helps to output the egg tray with missing eggs separately.

[0004] The technical solution of this utility model is as follows: an egg tray egg product missing detection and distribution device, including a frame, a conveying mechanism is arranged horizontally on the frame, a fork mechanism for detecting whether there are eggs on the egg tray is arranged on the upper side of the conveying mechanism, and a receiving frame is arranged on the rear side of the output end of the conveying mechanism. The receiving frame can be raised and lowered and is used to dock with the conveying mechanism to receive the egg tray with eggs.

[0005] Furthermore, the fork mechanism includes a mounting frame spanning the upper side of the conveying mechanism. Several oblique forks are spaced apart on the mounting frame along the width direction of the conveying mechanism. The upper ends of the oblique forks are rotatably connected to shafts longitudinally mounted on the mounting frame. A U-shaped pressure frame is hinged on the mounting frame and presses against the upper side of the oblique forks. A sensor is provided for detecting whether the U-shaped pressure frame is raised.

[0006] Furthermore, a limiting protrusion is provided at the upper end of the inclined fork, and a limiting stop bar is provided longitudinally on the rear side of the limiting protrusion to abut against the limiting protrusion. A reset spring connected to the mounting bracket is provided on the limiting protrusion.

[0007] Furthermore, a fixed plate is provided on the front side of the fork mechanism, spanning the upper side of the conveying mechanism. A pair of horizontally arranged stabilizing pressure bars are elastically connected to the fixed plate. The stabilizing pressure bars pass through the lower part of the fork mechanism and are movably connected to the frame at their rear ends.

[0008] Furthermore, the front end of the stabilizing pressure rod has a connecting rod portion that curves upward and passes through the fixed plate. A washer is fixed on the connecting rod portion, and a spring is sleeved on the connecting rod portion between the washer and the lower side of the fixed plate.

[0009] Furthermore, the conveying mechanism is a chain plate type conveying mechanism, and baffles are spaced apart on the chain plate conveyor belt of the chain plate type conveying mechanism.

[0010] Furthermore, a support frame is provided on the rear side of the conveying mechanism, the rear part of the receiving frame is placed on the support frame, a fixed frame is installed on the front part of the receiving frame, the fixed frame is slidably connected to the frame, a fixed frame is installed on the frame above the output end of the conveying mechanism, and an inclined cylinder with its lower end hinged to the fixed frame is hinged to the fixed frame.

[0012] Furthermore, a receiving mechanism for receiving empty egg trays is provided on the lower side of the output end of the conveying mechanism.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This device is convenient for detecting whether there are any missed eggs on the egg trays. Through the linkage between the fork mechanism and the receiving frame, it helps to output the egg trays with missed eggs separately, avoiding affecting the collection of empty egg trays.

[0015] 2. The fork mechanism of this device can be flipped independently by the inclined forks, which helps to reduce the resistance of the egg tray moving backward; at the same time, the number of inclined forks is the same as the number of rows of eggs on the egg tray, which also helps to improve the accuracy of detection.

[0016] 3. The device is equipped with a pair of stabilizing pressure bars in conjunction with a chain conveyor belt with baffles, which helps to stably transport the egg tray backward and avoids the situation where the egg tray cannot be transported backward due to the resistance of the fork mechanism.

Detailed Implementation

[0022] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0023] refer to Figures 1 to 4

[0024] An egg tray egg product missing detection and distribution device includes a frame B1, a conveying mechanism B2 arranged horizontally on the frame, a fork mechanism B3 for detecting whether there are eggs on the egg tray located on the upper side of the conveying mechanism, and a receiving frame B4 located on the rear side of the output end of the conveying mechanism. The receiving frame can be raised and lowered and is used to dock with the conveying mechanism to receive egg trays containing eggs.

[0025] In this embodiment, to better detect whether there are any missed eggs on the egg tray, the fork mechanism includes a mounting frame B31 straddling the upper side of the conveying mechanism. Several oblique forks B32 are spaced apart on the mounting frame along the width direction of the conveying mechanism. The upper ends of the oblique forks are rotatably connected to shafts B33 longitudinally mounted on the mounting frame. A U-shaped pressure frame B34 is obliquely mounted on the mounting frame, pressing against the upper front part of the oblique forks. The ends of the rods on both sides of the U-shaped pressure frame are rotatably connected to the mounting frame. A sensor for detecting whether the U-shaped pressure frame is raised is mounted on the mounting frame. The sensor is electrically connected to the drive mechanism of the receiving frame via a controller, thus connecting the receiving frame and the fork mechanism.

[0026] For example, there are 5 diagonal forks, the same as the number of rows of eggs on the egg tray. When there are eggs on one row of the egg tray, as the egg tray is conveyed backward by the conveyor mechanism, the eggs touch the diagonal forks. Under the action of the backward thrust, the diagonal forks rise and drive the U-shaped pressure frame to rise around the hinge point. When the sensor detects that the U-shaped pressure frame has risen, it sends a feedback signal to the controller. The controller drives the drive mechanism of the receiving frame to lower the receiving frame and connect it with the conveyor mechanism. After receiving a single egg tray, the receiving frame rises and resets.

[0027] In this embodiment, to allow the angled fork to better contact the eggs, the lower end of the angled fork is provided with an arc-shaped portion B321 that curves downwards, and the upper end of the angled fork is fixed with a hinge block B322 whose lower part is rotatably connected to the shaft. The upper end of the hinge block is provided with a limiting protrusion B323, and a limiting stop bar B35 is longitudinally provided on the rear side of the limiting protrusion on the mounting bracket, which abuts against the limiting protrusion. The height of the lower end of the angled fork is controlled by the cooperation between the limiting stop bar and the limiting protrusion. A return spring B36 connected to the mounting bracket is provided on the limiting protrusion, which enables the angled fork to automatically descend and return to its original position after rising.

[0028] In this embodiment, in order to ensure stable transport of the egg tray within the conveying mechanism, a fixed plate B51 is provided on the front side of the fork mechanism, spanning the upper side of the conveying mechanism. A pair of horizontally arranged stabilizing pressure rods B52 are elastically connected to the fixed plate. The stabilizing pressure rods pass between the lower parts of two adjacent oblique forks of the fork mechanism and are movably connected to the frame at their rear ends. The pair of stabilizing pressure rods prevent the egg tray from tilting when it touches the fork mechanism.

[0029] In this embodiment, the front end of the stabilizing rod has a connecting rod portion B521 that curves upward and passes through the fixed plate. A washer B522 is fixed on the connecting rod portion, and a spring B523 is sleeved on the connecting rod portion between the washer and the lower side of the fixed plate, allowing the stabilizing rod to elastically rise and fall. The upper end of the connecting rod portion passes through the fixed plate and is screwed with a locking nut. The rear end of the stabilizing rod has a connecting portion that curves upward and is movably connected to the frame.

[0030] In this embodiment, in order to facilitate the transfer of egg trays, the transfer mechanism is a chain plate type transfer mechanism. The chain plate type transfer mechanism has baffles spaced apart on the chain plate conveyor belt, which can better push the egg trays to move backward.

[0031] In this embodiment, in order to achieve the lifting and lowering of the front end of the receiving frame, a support frame B6 is provided on the rear side of the conveying mechanism, the rear part of the receiving frame is placed on the support frame, and a fixed frame B41 is installed on the front part of the receiving frame. The lower parts of both sides of the fixed frame are slidably connected to the frame. A fixed frame B12 located above the output end of the conveying mechanism is installed on the frame. An inclined cylinder B42 with its lower end hinged to the fixed frame is hinged to the fixed frame, so that the lifting and lowering of the front end of the receiving frame is achieved by the extension and retraction of the inclined cylinder.

[0032] In this embodiment, notches B11 are provided on both sides of the frame, and guide plates B411 located outside the notches are fixed on the lower parts of both sides of the fixed frame. The lifting and guiding are achieved by the cooperation of the notches and the guide plates.

[0033] In this embodiment, a guide frame B43 with a certain distance between it and the receiving frame is installed at the lower end of the fixed frame, and wear-resistant plastic parts are provided on both sides of the fixed frame to improve wear resistance during lifting.

[0034] In this embodiment, a receiving mechanism for receiving empty egg trays is provided on the lower side of the output end of the conveying mechanism, so as to receive the empty egg trays output by the conveying mechanism. The receiving mechanism may be an egg tray stacking mechanism, etc.

[0035] During operation, empty egg trays are directly fed into the receiving mechanism. When an egg tray fed by the conveyor has uncollected eggs, the corresponding diagonal fork is lifted by the eggs, causing the U-shaped pressure frame to rise. The sensor feeds back the signal to the controller, causing the receiving frame to descend and connect with the conveyor. Egg trays with eggs are then fed into the receiving frame. After receiving a single egg tray, the receiving frame rises and resets, pushing the next egg tray backward on the receiving frame. After a certain number of egg trays have moved on the receiving frame, the egg trays with eggs are manually collected and processed.

[0036] 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 or 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).

[0037] 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.

[0038] 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.

[0039] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
