Abstract

The invention provides a rolling type egg weighing device which comprises an oblique guide rail, a horizontal guide rail, a weighing bracket, at least one weighing sensor, a plurality of weighing delivery rods, two chain wheel transmission devices, two chain supporting blocks and two arc-shaped guide blocks. A gap is reserved between the oblique guide rail and the horizontal guide. The rail weighing bracket is freely arranged at the gap position and connected with the weighing sensors. The weighing delivery rods are connected to rollers of chains of the chain wheel transmission device, the rollers are abutted against by the arc-shaped guide blocks to roll on the chain supporting blocks, the middle transition sections of the chain supporting blocks are provided with rising guide sections and horizontal guide sections, the rising guide sections extend from the upper portion of the oblique guide rail to the upper portion of the weighing bracket, and the horizontal guide sections extend from the upper portion of the weighing bracket to the inlet end of the horizontal guide rail. Eggs rolling into the weighing bracket can break away from the weighing delivery rods and freely roll in a deceleration mode due to the fact that pushing force does not exist, and accordingly weighing is more accurate.

Description

The roller weighing device of birds, beasts and eggs

Technical field

The present invention relates to a kind of weighing device of birds, beasts and eggs.

Background technology

Because weight is the important parameter characterizing quality of poultry eggs, therefore on the production line of poultry egg products, often needs to sort birds, beasts and eggs, come classification processing or shipment by the weight size of birds, beasts and eggs.

The birds, beasts and eggs weighing device of current production line is all namely complete to weigh in the process of the conveying of birds, beasts and eggs, disclosed in 2013-02-13, publication number is that the Chinese invention of 102919162A discloses birds, beasts and eggs level run many rows electronic-weighing sorter, weighing device wherein comprises weighing frame, to weigh push rod, to weigh guide rail, holder incubator tray and main drive gear, two at least two groups being a composition is longitudinally arranged guide rail of weighing is fixed on weighing frame, drag the push rod of weighing that can vertically move by main drive gear to be arranged in above guide rail of weighing and orthogonal with guide rail of weighing, weighing frame has the holder incubator tray identical with set of rails number of weighing, above holder incubator tray, there is holder egg circular arc both sides, in holder incubator tray, electronic weight sensor is installed, described electronic weight sensor is electrically connected with control device.But because the holder incubator tray in this invention has holder egg circular arc to take spacing birds, beasts and eggs by both sides, top to weigh, birds, beasts and eggs are when push rod of weighing is shifted onto on holder incubator tray, due to the effect of inertia, birds, beasts and eggs are made to roll back and forth at holder egg circular arc unavoidably, thus have impact on the accuracy of weighing, therefore need the necessity improved.

Summary of the invention

The technical problem to be solved in the present invention, be the roller weighing device that a kind of birds, beasts and eggs are provided, birds, beasts and eggs can be made to slow down and to roll across bracket of weighing, and can depart from and weigh conveying lever and become free state, reduce birds, beasts and eggs and have impact on the accuracy of weighing because of the reason of the active force of the conveying lever that rolls back and forth or be subject to weighing.

The present invention is achieved in that a kind of roller weighing device of birds, beasts and eggs, comprise an inclined guide rails, a horizontal guide rail, weighs bracket, at least one LOAD CELLS, a plurality of conveying lever of weighing, two sprocket transmission devices, two chain trays and two arc guide blocks; The permutation delivery track of the high-end linking birds, beasts and eggs of described inclined guide rails, the contiguous described horizontal guide rail of low side also and between horizontal guide rail has a gap; Described bracket of weighing freely is located at this gap location and connects described LOAD CELLS; The two ends of described conveying lever of weighing are connected on the roller of the chain of sprocket transmission device described in, and move forward above inclined guide rails and horizontal guide rail under the drive of described sprocket transmission device; Described chain tray distributes along the both sides of inclined guide rails and horizontal guide rail, and establish the roller of below with support chains of chain, and the first half section of the top edge of chain tray is parallel to inclined guide rails, second half section is parallel to horizontal guide rail, middle transition section has an arc curve, and this arc curve has a lifting lead section and a horizontal boot segment, lifting lead section by described inclined guide rails top and extend to directly over bracket of weighing, horizontal boot segment is by extending to the upstream end of described horizontal guide rail directly over described bracket of weighing; Described two arc guide blocks lay respectively at directly over the middle transition section of a chain tray, and the lower limb of this arc guide block has the identical arc curve of chain tray, and pushes against the roller of described chain on chain tray.

Further, the low side of described inclined guide rails has a horizontal end, and described deceleration boot segment is positioned at directly over this horizontal end.

Further, described permutation delivery track for many row's permutation delivery tracks, described inclined guide rails for arranging inclined guide rails more, described horizontal guide rail is many row of horizontal guide rail; Described bracket of weighing arranges for bracket of weighing more, and bracket of weighing of arranging is rearranged by multiple bracket of independently weighing more, and each bracket of independently weighing all connects a LOAD CELLS.So many row is arranged, and can improve the efficiency of weighing of birds, beasts and eggs.

Further, described LOAD CELLS is all electrically connected a control device, makes the weighing data of each LOAD CELLS all can be sent to control device, is received and dispatched and process by control device.

The invention has the advantages that: by arranging a lifting lead section and a horizontal boot segment on chain tray, inclined guide rails is entered after birds, beasts and eggs permutation on permutation delivery track is neat, side is against weighing conveying lever be rolled to the horizontal end of inclined guide rails along inclined guide rails, when chain enters lifting lead section along chain tray, the conveying lever speed in the horizontal direction of weighing be connected on chain slows down relatively, drive abuts against the birds, beasts and eggs of weighing on conveying lever and also slows down, when chain enters the horizontal boot segment of chain tray, the speed of weighing in conveying lever horizontal direction be connected on chain is accelerated, now birds, beasts and eggs disengaging weighs conveying lever again owing to doing deceleration Free-rolling without motive force, the birds, beasts and eggs of automatic rolling are also sitting at and weigh on bracket simultaneously, now LOAD CELLS sends the weight data of this egg to control device, so reduce the accuracy that to have impact on birds, beasts and eggs because of the reason of the active force of the conveying lever that rolls back and forth or be subject to weighing and weigh, to be weighed complete, then do accelerated motion, until reach the normal transporting velocity of follow-up permutation delivery track by the conveying lever promotion birds, beasts and eggs of weighing be close to thereafter.
