Description

Technical Field

[0001] The invention relates to the technical field of primary processing of poultry eggs, and further to poultry egg weight grading and packaging equipment, and in particular to a novel transition conveying device for poultry egg grading and packaging. Background Art

[0002] At present, domestic equipment manufacturers deal with grading and loading separately, and the egg grading equipment and the egg loading equipment are two sets of equipment. Generally, independent grading equipment can directly discharge eggs on the conveyor belt of the corresponding weight level after multi-row grading without loading, which requires a lot of manpower to pick up. The structure of the independent loading equipment is relatively complex, the speed is slow, and it is impossible to grade the weight of eggs. Simply and crudely connecting the independent loading equipment to the conveyor belt of the graded egg discharge outlet can realize grading and loading in one, but limited by the efficiency of the independent loading equipment, the efficiency of the whole machine is low. The price of the independent egg loading machine is relatively high. After the whole machine is formed, each grading channel needs to be connected to an independent egg loading machine, resulting in a high price for the whole machine. In order to organically combine the grading equipment with the loading equipment, the eggs transported in multiple rows must be converted into single-row conveying, because the low speed of multi-row conveying of eggs can improve the grading and weighing accuracy, and the eggs adjusted after conversion to single row are easier to enter the loading machine quickly, and the structure of the loading machine can be further simplified to reduce costs. Therefore, the multi-row to single-row transition device for poultry eggs can organically combine grading and packaging, ensuring high-efficiency and stable operation of the whole machine while reducing costs.

[0003] In the field of egg grading and packaging, since foreign companies started earlier and have accumulated many years of technology in this field, several foreign companies have mastered the integrated technology of egg grading and packaging. Foreign companies use a clamping mechanism in the transition scheme of multi-row to single-row egg and the single-row egg-carrying conveyor. For example: the Dutch MOBA company uses a reciprocating push rod device to send eggs to the single-row egg-carrying conveyor with a clamping structure in the transition of multi-row to single-row; Japan Kyowa Machinery uses a multi-row to single-row transition device with a clamping structure to send eggs to the single-row conveyor with a support structure. Foreign equipment must have a clamping structure in one of the two devices of multi-row to single-row transition and single-row conveying. The opening of the clamping structure is fixed, and eggs that are too small cannot be clamped, and eggs that are too large cannot enter, so the clamping structure is suitable for eggs with smaller appearance differences. At present, many egg varieties in China have very thin eggshells, and the clamping structure will increase the breakage rate of such thin-shell eggs. In addition, the domestic demand for duck eggs is increasing, especially salted duck eggs and preserved eggs. Therefore, the country requires that duck eggs, preserved eggs and chicken eggs be treated the same way and must be graded and loaded. Since the outer dimensions of duck eggs vary greatly, the clamping mechanism is not applicable. Summary of the invention

[0004] The present invention aims to address the technical defects of the prior art and provide a new transition conveying device for poultry egg grading and packaging, so as to solve the technical problems that the current poultry egg grading equipment and the loading equipment operate independently, the overall processing efficiency is low, and the equipment cost is high.

The 17 egg claws and the egg claw support assembly 14 egg claw left support 142 pivot point positioning hole and the 11 base assembly 12 support 122 egg claw opening and closing frame fixing hole are connected by a latch (as shown in the figure above), and a torsion spring is installed in the pin shaft so that the 14 egg claw left support is subjected to a torsion force around the 142 pivot point positioning hole in a clockwise direction (as seen from the front direction in the figure above). Similarly, the 17 egg claws and the egg claw support assembly 16 egg claw right support 161 positioning hole and the 11 base assembly 12 support 122 egg claw opening and closing frame fixing hole are connected by a latch (as shown in the figure above), and a torsion spring is installed in the pin shaft so that the 16 egg claw right support is subjected to a torsion force around the 161 positioning hole in a counterclockwise direction (as seen from the front direction in the figure above). The 18 single-row egg carrying device is inserted into the transport chain at a specific spacing to form a single-row egg carrying conveying device.

[0065] Implementation

[0066] Specific implementation method 1 Fig.19 shown.

[0067] Fig.19 It can be seen that when the eggs are weighed, they move in the direction of the multi-row weighing movement of 194 eggs. After passing through the 9 transition device, the eggs will enter the single-row conveying egg-carrying device. The multi-row movement direction is perpendicular to the single-row movement direction. Because the directions are perpendicular, the device is called a multi-row to single-row transition device. During the whole process, the multi-row conveyed eggs always move at a lower uniform speed, while the single-row conveying egg-carrying device always moves at a uniform high speed. The 9 transition device performs variable speed movement under the action of the cam.

[0068] After the eggs have been adjusted and weighed, they are in Fig.19 At this time, the small end of the egg faces right and the big end faces left. After passing through the 192 flip guide, the egg will fall into the 9 transition device. Due to the special structure of the 192 flip guide with one end long and the other end short, the egg falls into the 9 transition device with the small end facing down and the big end facing up. The whole falling process is as follows Fig. 20 shown.

[0069] Fig. 20 In the figure, a is the initial state, and b is the state where the eggs fall obliquely. When the eggs enter the transition device 9, since the egg receiving slot of the transition component 6 is funnel-shaped, the eggs will be in the state of Figure c after entering the transition device 9. Fig.21 shown.

[0070] When the eggs have not entered, as shown in state a of the above figure, the 2 egg receiving assemblies on the left and the 2 egg receiving assemblies on the right are both in contact with the lower limit rod 31 under the action of the counterweight iron block 22. When the eggs enter, as shown in state b of the above figure, since the weight of the eggs is heavier than the counterweight iron block 22, the 2 egg receiving assemblies rotate around the long opening and closing rod 41 and the short opening and closing rod 51 until the 2 egg receiving assemblies contact and stop with the upper limit rod 32. The entire entry process uses the lever principle to buffer the eggs entering the transition device 9, and even eggs with very thin eggshells can be handled calmly.

[0071] In the above process, the transition drive assembly 8 makes the transition device 9 in a static waiting state through the cam. Fig. 22 a), 8 transition drive assembly controls 9 transition device to the right through cam ( Fig.19 Right-hand direction) accelerates, when the speed of the transition device 9 moving to the right is equal to the speed of the single-row egg conveying device and the order receiving slot of the transition device 9 is just above the egg receiving slot of the single-row egg carrying device 18 ( Fig. 22 b), then the transition device 9 and the single-row egg conveying device perform a constant speed following motion, and when the transition device 9 continues to move to the right, the 92 opening and closing guide rail opens the egg receiving slot of the transition device 9, and the poultry eggs enter the single-row egg conveying device ( Fig. 22 c) After the eggs enter the single-row egg conveyor, the transition device decelerates until the speed reaches zero, and then immediately returns to wait for the next row of eggs to enter, and so on. The specific process is as follows Fig. 22 shown.

[0072] After passing through the 9 transition device, the eggs enter the single-row egg loading device and then enter the tray loading machine.

[0073] When the egg carrier transports the eggs to the corresponding position and needs to be released, the egg carrier can be opened by rotating an actuator such as an electromagnet or a cylinder to allow the eggs to enter the tray loading machine.

[0074] Specific implementation method 2a Fig.23a shown.

[0075] This example uses a rotating electromagnet as an example to describe its action process. Before the egg-carrying device transports the eggs to the corresponding position, the limit protrusion 132 of the 13 switch lever blocks the 141 working protrusion surface of the 14 egg claw left support. At this time, even if the torsion spring gives the 14 egg claw left support a clockwise torque, the 14 egg claw left support will not rotate. Under the pulling action of the 171 connecting rod, the 16 egg claw right support will not rotate counterclockwise, even if the torsion spring gives the 16 egg claw right support a counterclockwise torque. Therefore, the egg slot formed by the 14 egg claw left support and the 16 egg claw right support is in a closed state, and the eggs will not fall. When the egg-carrying device is extended, the egg-carrying device will not rotate. Fig.23a When the poultry eggs are transported to the corresponding position in the direction shown, the rotating electromagnet assembly 231 is actuated, and the rotating electromagnet assembly 231 will stop the working part 133 of the switch lever 13, so that it rotates around the positioning hole of the support 131, and the limiting protrusion 132 of the switch lever 13 is separated from the working protrusion surface 141 of the left support of the egg claw 14, and the state is as follows Figure 23b shown.

[0076] Subsequently, the left support of the 14 egg claws and the right support of the 16 egg claws open the egg receiving slot to release the eggs under the action of their respective torsion springs and the 171 connecting rods, and the state is as follows: Fig.23c As shown:

[0077] 14 egg claw left support after egg release Fig.23c The egg carrier is installed on a revolving chain. After releasing the eggs, in the subsequent movement, only one lever is needed to rotate the left support of the egg claw 14 counterclockwise to reset the switch lever 13 and then release the left support of the egg claw 14. At this time, the egg carrier is in the open state. Fig.23a The egg carrying device is in the closed state. If it is opened, it will remain in the open state without any treatment. If it is in the closed state, it will remain in the closed state without any treatment. That is, the egg carrying device of this structure has the function of maintaining the current state, so it is stable and reliable during operation.

[0078] This case takes the conversion of 6-row conveyor of poultry eggs to single-row conveyor as an example, and is applicable to situations with more than 2 rows.

[0079] The embodiments of the present invention are described in detail above, but the contents are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the scope of the present invention shall be included in the protection scope of the present invention.
