Description

Egg transfer and discharge device using an inclined cam {Egg Transfer And Discharge Appartus Using Inclined Cam}

The present invention relates to an egg conveying and releasing device using an inclined cam, and in particular, the opening and closing speed of a bucket carrier installed to reciprocate by a drive cam at the egg discharge end side is increased by the inclined cam, so that per hour It relates to an egg conveying and releasing device using an inclined cam that maximizes the amount of conveying and releasing eggs.

In general, eggs go through various work processes such as various inspections, weighing, and container packaging while being produced in chicken farms and shipped as a single product. It is carried out during conveyance or at the end of conveyance, and eggs are conveyed so that this treatment is easy.

For example, the processing of eggs is carried out after sorting based on physical properties such as weight, and then transported to pack them in packaging containers such as egg seats (egg packs). An example of such an egg transport (transfer) device is is published on

Patent Document 1 relates to a transfer tool of an egg sorter that is 'coupled to a chain, easy to combine with a transfer tool for transporting eggs, and allows eggs to be sorted quickly.' It is made by opening the lower side of the feeder having a ^ shape so that the lower side of the feeder is inserted into the chain and coupled, and installing a discharge means for releasing the egg on the side of the chain to which the feeder is coupled and moving. It is easy to combine, and the egg is easily discharged.'

Patent Document 2 relates to an egg conveying device of an 'egg sorter', and is a mechanical mechanism that transfers sorted eggs contained in a basket to an egg carton located vertically downward. The kinematic characteristics required for this mechanism are that while the basket contains and transports the eggs, it descends slowly so that the eggs are not damaged, so that the acceleration does not exceed the gravitational acceleration. Should be. The transfer device of the existing egg sorter is operated by a cam or consists of a slider-crank mechanism. In the case of using a cam, the production cost is high and it is difficult to manage, and the slider crank mechanism has a limit in increasing the operating speed of the egg sorter because the feed speed is constant in the case of descending and ascending movements. In order to improve this, the present invention has improved the structure of driving the sorter using a quick return mechanism. Due to this device, it operates at a low speed when descending with eggs in the basket and at a high speed in an upward movement in which only the basket moves without eggs, enabling high-speed sorting work, thereby increasing productivity. In addition, the manufacturing cost is reduced, the failure rate is low even when used for a long time, and maintenance is easy.'

Patent Document 3 also relates to an 'egg transfer device' and includes a 'polygonal frame; A first sprocket coupled to the upper front portion of the polygonal frame, a second sprocket coupled to the upper rear portion of the frame, one or a plurality of third sprockets coupled to the lower portion of the frame, and the first sprocket to the third sprocket. a transfer unit including a chain coupled to and sequentially passing through the first sprocket to the third sprocket; a plurality of bucket parts coupled to the chain; a supply unit provided on an upper portion of the frame; and a driving unit including a first rotating shaft coupled to the first sprocket, a fourth sprocket coupled to one end of the first rotating shaft, and a driving motor rotating the fourth sprocket. Accordingly, the fourth sprocket is coupled in a state in which one end of the first rotating shaft coupled to the first sprocket is exposed to the outside of the frame, and the driving motor is configured to rotate the fourth sprocket, so that the first sprocket to the third sprocket are By making it rotate, there is an effect that the chain passing through the first sprocket to the third sprocket can be moved at a stable speed.'

However, in the case of the prior art of Patent Document 1, the eggs are loaded and transported on each of the transfer units coupled to the chain, and the eggs transferred by the transfer unit coincide with the discharge means acting in the direction orthogonal to the transfer unit on one side of the transfer chain. There is a problem in that the egg cannot be discharged quickly due to the operation of the conveying chain of the conveyor and the linked operation of the discharge means, because the operation of the discharge means pushes the eggs loaded in the conveyor to the outside whenever it is discharged.

The prior art of Patent Document 2 uses a rapid return mechanism for rapid transfer of eggs, but this rapid return mechanism operates at a low speed when descending with eggs contained in the basket and at a high speed during an upward movement in which only the basket moves without eggs. So, since the vertical movement speed is different from each other, this also has the same problem as Patent Document 1, that is, the problem that the transfer speed of the egg is slow.

On the other hand, in the case of Patent Document 3, the egg supply unit is driven by a cam, but since the pinion gears installed in each of the buckets for supply are engaged with the rack gear and rotate to perform the closing and opening operations of the egg supply bucket, the pinion gear The above problem that the closing and opening operation of the bucket is delayed corresponding to the rotation diameter of the bucket is contained as it is.

Therefore, there is an urgent need to develop an egg conveying and releasing device capable of rapidly releasing eggs as well as conveying them.

To achieve a conveying or releasing state of eggs includes a rotating ball 155.

An example of an operation of the egg conveying and releasing device using the inclined cam according to the present invention having the above configuration will be described again with reference to the drawings.

The egg conveying and releasing device 100 using an inclined cam according to the present invention is continuously installed in the 'automatic egg sorting and conveying apparatus' (Publication No. 10-2021-0054276) and transferred from the 'automatic egg sorting and conveying apparatus' After receiving the eggs vertically, they are stably and quickly released in a vertical state while conveying them to the egg transfer unit 110 side.

For example, the state in which the egg conveying and releasing device 100 using an inclined cam according to the present invention receives eggs transferred from the automatic egg sorting and conveying device (Publication No. 10-2021-0054276) of the bucket carrier unit 130 This is when the egg conveying and releasing buckets 134 are closed as shown in FIGS. 3 and 4 .

In the closed state of the egg conveying and releasing buckets 134, the drive cam 142 coupled to the drive shaft 122 of the drive unit 120 shown in FIG. 1 and rotated together rotates in the direction of the arrow ⓑ as seen in FIG. It occurs when the drive cam 142 pushes the cam lever 146 in the process. When the driving cam 142 pushes the cam lever 146, the cam lever 146 rotates in the direction of the arrow ⓒ with the hinge part 145 as a support point, and at this time, the elastic member 147 (see FIG. 1) renal status. When the cam lever 146 rotates in the direction of the arrow ⓒ with the hinge part 145 as a support point, the cam lever 146 is connected to the movable bar 132 of the bucket carrier part 130 via the ball joint 144 is pulled in the same arrow ⓒ direction so that the left end of the movable bar 132 coupled to move to the inclined cam portion 150 is positioned toward the upper side of the inclined cam portion 150.

That is, when the cam lever 146 is rotated in the direction of arrow ⓒ by the rotation of the drive cam 142, the cam lever 146 moves the movable bars 132 connected via the ball joint 144. The movable bars 132 of the bucket carrier 130 and the egg conveying and releasing buckets 134 are moved by the fixing bracket 131 by pulling in the direction of the arrow ⓒ, which is the same as the rotation direction of the cam lever 146. While being guided, the cam lever 146 moves in the same direction as the arrow ⓒ, so that the left end of the movable bar 132 reaches the uppermost end of the inclined cam 150 as seen in FIG. do.

As shown in FIGS. 1 and 2A, one ends of the movable bars 132 are coupled to both sides of the inclined cam groove 151 of the inclined cam part 150 through a fixed holder 153 and a rotating ball 155, respectively. Since the movable bars 132 are fixedly coupled, the fixed holders 153 coupled with the inclined cam groove 151 through the rotary ball 155 are moved to the inclined cam groove due to the movement of the movable bars 132. When moving to an adjacent position close to the top of 151, the rotation ball 155 of the fixing holder 153 is used as a support point to induce rotation in the direction of the arrow in FIGS. 3 and 4, The fixing holder ( 153) to be rotated in the direction indicated by the arrows in FIGS. 3 and 4. Rotation of the movable bar 132 in the direction of the arrows in FIGS. 3 and 4 causes the egg transport and release buckets 134 coupled to the movable bars 132 to be closed, thereby transporting eggs in a closed state and The inside of the release buckets 134 allows eggs to be stably received in an upright state. (See FIGS. 1, 2a and 4)

Contrary to the above, when the drive cam 142 coupled to the drive shaft 122 of the drive unit 120 and rotated together continues to rotate in the direction of the arrow ⓑ and escapes from the cam lever 146, as shown in FIG. 2b, The elastic member 147 (see FIG. 1) coupled to the cam lever 146 and forming an elongated state is restored to its original position, resulting in a pulling action, which causes the cam lever 146 to use the hinge portion 145 as a support point. to rotate quickly in the direction of the arrow ⓓ, so that the plurality of movable bars 132 connected via the cam lever 146 and the ball joint 144 are pushed in the same direction as the rotation of the cam lever 146 in the direction of the arrow ⓓ As a result, the movable bars 132 are moved in the direction of the arrow ⓓ while being guided by the fixing bracket 131, and are coupled to the movable bar 132 to convey and release eggs containing eggs 20 Like the movable bar 132, the buckets 134 also perform an egg conveyance action moving in the direction of the arrow ⓓ, which is the same as the moving direction of the egg conveyer 110.

The action of conveying eggs and releasing buckets 134 by the movable bar 132 by the pushing force of the cam lever 146 is located above the inclined cam groove 151 of the inclined cam part 150, The existing fixed holder 153 and the rotating ball 155 move along the inclined cam groove 151 like the movable bar 132 and move to the lowermost end of the inclined cam groove 151. When the fixed holder 153 is located at the lowermost end of the inclined cam groove 151, the fixed holder 153 of the movable bars 132 moves along the inclined cam groove 151 to the lowermost end away from the uppermost end. In the process of moving to, the rotational force induces the movable bar 132 to rotate in the direction ⓕ, which is opposite to the direction of the arrow ⓔ (see FIG. 4) when located at the top using the rotating ball 155 as a fulcrum. As in the case of the closing operation, the rotating ball 155 and the ball joint 144 are used as support points to rotate while being supported by the fixing bracket 131 (see FIGS. 5 and 6).

Rotation of the movable bars 132 in the direction of the arrow ⓕ in FIGS. 5 and 6 results in an open state of the egg conveying and releasing buckets 134 coupled to the movable bars 132 as shown in FIG. 6 . The eggs are quickly discharged into the inside of the egg transfer buckets 114 of the transfer chain 110 corresponding to the egg transfer and release buckets 134, respectively, so that the transfer chain 110 removes the eggs of the egg transfer buckets 114. After transferring to the next step, the empty buckets are moved to a position where eggs can be received from the egg conveying and releasing buckets 134 again.

In the above, the operation of the egg conveying and releasing device 100 using the inclined cam has been described step by step to help understanding, but in reality it is operated continuously, and the egg conveying and releasing device 100 using the inclined cam according to the present invention The operation is repeated as long as eggs are supplied. In particular, the operation of conveying and discharging eggs by the bucket carrier part 130 corresponds to the moving length of the inclined cam groove 151 of the inclined cam part 150, thereby closing the buckets and By the configuration in which the opening action is executed, the carrier unit 130 has an economic benefit of allowing the egg to be conveyed or released quickly in response to the moving length of the inclined cam groove 151.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, the present invention is not limited thereto, and within the technical spirit of the present invention, by those skilled in the art It is clear that modifications and improvements are possible.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be clarified by the appended claims.

According to the present invention, it has the economic benefit of speeding up the transport and release of eggs by the bucket.
