DETAILED DESCRIPTION

[0024] In order to make the above features and advantages of the utility model more obvious, the following embodiment is taken as an example, and the detailed description is made as follows in combination with the drawings, but the utility model is not limited to this.

[0025] REFERENCE Figs. 1 to 4

[0026] An egg tray stacking device, comprising a frame, a pair of egg tray receiving plates C2 are arranged on the lower side of the output end of the egg tray conveying belt C1, a swing plate C3 is arranged between the rear parts of the pair of egg tray receiving plates and is used for pushing the egg tray falling on the pair of egg tray receiving plates forward to form a vertical state, and an elastic blocking mechanism C4 is arranged on the front side of the swing plate and is used for abutting against the front side of the frontmost egg tray.

[0027] In the embodiment, a rotation shaft C31 driven by a driving mechanism to realize reciprocating forward and reverse rotation is arranged on the lower side of the rear part of the pair of egg tray receiving plates on the frame, the swing plate passes through between the pair of egg tray receiving plates and is fixedly connected with the rotation shaft through the fixing block C32. The driving mechanism can be a stepping motor or a crank rocker mechanism to drive the rotation shaft to realize forward and reverse rotation of 20-50°, for example, 35°, so that the egg tray is received from the lower side of the output end of the egg tray conveying belt and is pushed forward to the side of the elastic blocking mechanism.

[0028] In the embodiment, the elastic blocking mechanism comprises a limiting rod C41 arranged between the rear parts of the pair of egg tray receiving plates, a shaft C42 is arranged on the lower side of the limiting rod and is rotationally connected with the frame, the shaft is fixedly provided with a stop rod C43 passing through between the pair of egg tray receiving plates at the upper end, and an elastic member is arranged on the shaft and abuts against the front side of the limiting rod when the stop rod does not receive the egg tray, so that the egg tray can be kept in the vertical state and helps to avoid the forward toppling of the frontmost egg tray when the device starts to work.

[0029] In this embodiment, the elastic member is a torsion spring C44 which is sleeved on the shaft and fixed at one end to the shaft, and the other end is fixed to the frame, so as to ensure that the shaft with the stop rod has a backward rotating elastic force. After the number of egg tray stacks gradually increases, the stop rod will gradually tilt forward under the force of the egg tray and push the egg tray to move laterally along a pair of egg tray supporting plates, so that the egg tray can be stacked in sequence along the lateral direction (the length direction of the egg tray supporting plate), and the length of the egg tray supporting plate determines the length of the stacked egg tray, thereby reducing the number of times that the staff stops to carry the egg tray; when the staff takes out the stacked and collected egg tray, the stop rod will reset under the elastic force and abut against the limiting rod.

[0030] Or in another embodiment, the elastic member includes a connecting plate fixed at one end of the shaft, and a spring connected to the frame is installed on the connecting plate, or a spring rod or gas spring connected to the frame is hinged on the connecting plate, so that the shaft has a backward rotating elastic force.

[0031] In this embodiment, in order to avoid noise when the stop rod abuts against the limiting rod, a buffer pad layer is sleeved on the limiting rod, and a plastic layer is sleeved on the stop rod.

[0032] In this embodiment, at least one set of elastic limiting stop pieces C5 are arranged on both sides of the upper rear part of the pair of egg tray supporting plates on the frame and between the swing plate and the elastic blocking mechanism, so as to avoid the egg tray from tilting backward after the swing plate pushes the egg tray to contact the stop rod. Specifically, two sets of elastic limiting stop pieces are arranged on both sides between the swing plate and the elastic blocking mechanism, and are arranged in an upper and lower interval.

[0033] In this embodiment, the elastic limiting stop piece includes a fixed seat C51 installed above the egg tray supporting plate, a horizontal limiting plate C52 rotatably connected to the rear end of the fixed seat is arranged on the fixed seat, and an elastic mechanism is arranged between the rear end of the horizontal limiting plate and the fixed seat, so that the front end of the horizontal limiting plate is obliquely arranged above the egg tray supporting plate, and the front end of the egg tray supporting plate abuts against the rear side of the egg tray, so as to avoid the egg tray from tilting backward.

[0034] In this embodiment, in order to better stack the egg tray, side plates C53 are arranged on the outer sides of the egg tray supporting plates on the frame, and a channel is formed between the two side plates; the fixed seat is installed on the outer side of the side plate, and an avoiding opening C54 for the horizontal limiting plate to pass through is arranged on the outer side of the side plate, so that the horizontal limiting plate extends into the channel.

[0035] In this embodiment, in order to better abut against the rear side of the egg tray, the front end of the horizontal limiting plate has an extension C55 which obliquely penetrates out of the avoiding opening, and the inclined surface of the extension allows the last egg tray to better abut against the protruding part C56 on the front part of the horizontal limiting plate.

[0036] In the embodiment, the elastic mechanism comprises a protrusion C57 fixed at the rear part of the horizontal limiting plate, a horizontal spring C58 is installed on the protrusion, a rear stopper C59 is arranged on the fixed seat and abuts against the rear end of the horizontal spring, so that the horizontal limiting plate always has a force turning inward.

[0037] In the embodiment, the egg tray conveying belt can be a chain plate type conveying belt, and baffles are fixed on the chain plate type conveying belt at intervals, so as to better drive the egg tray to move forward.

[0038] In the embodiment, the outer sides of the egg tray supporting plates are provided with raised edges C21 in the transverse direction, so as to limit the egg tray between the two raised edges.

[0039] If the utility model discloses or involves mutually fixed connecting parts or structural members, then, except for another declaration, fixed connection can be understood as: detachably fixed connection (for example, using bolt or screw connection), and also can be understood as: non-detachable fixed connection (for example, riveting, welding), of course, mutual fixed connection can also be replaced by integral structure (for example, integrally formed by using casting process) (obviously, except for integral forming process).

[0040] In addition, the terms used for indicating position relationship or shape in any technical solution disclosed by the utility model above include approximate, similar or close state or shape, except for another declaration.

[0041] Any component provided by the utility model can be assembled by multiple individual components, or can be an individual component manufactured by integral forming process.

[0042] The above is only the preferred embodiment of the utility model, and any change and modification made according to the patent application scope of the utility model shall belong to the coverage range of the utility model.
