Description

The present invention relates to an egg wrapping apparatus and an egg wrapping method. More specifically, the present invention relates to an egg wrapping apparatus and an egg provided with a container transport unit that transports a plurality of containers adjacent to each other so that the container seats are arranged in two rows. It relates to the packaging method.

In general, eggs transported from a poultry house by an egg collection conveyor are subjected to an egg washing and drying process, followed by inspection and weighing, sorted by class, and packaged in a container such as an egg pack made of synthetic resin.
In a conventional egg wrapping device, an endless chain is provided on a container transport unit that transports the container, and the endless chain is intermittently moved so that the container pushed by the dog fixed to the endless chain at a predetermined interval stops at the egg filling position. (See, for example, Patent Document 1).

In addition to such egg wrapping equipment, do not immediately wrap eggs in a container such as an egg pack made of synthetic resin for shipping, after selecting the eggs by equal class in order to produce appropriately according to the shipping volume. An egg wrapping apparatus is known that is temporarily stored in a temporary container such as a tray and then stored, and is refilled and packed in a container such as a synthetic resin egg pack for shipment according to demand.

Here, a conventional egg wrapping apparatus for refilling and packing a temporary container such as a tray into a container such as a synthetic resin egg pack for shipment will be described with reference to the drawings.
FIG. 5 is a view showing an operation when the conventional egg wrapping apparatus fills the eight-pack container 2 with the eggs E, and FIG. 6 is a view of the conventional egg wrapping apparatus shown in FIG. is there. As shown in FIGS. 5 and 6, the conventional egg wrapping apparatus is composed of an egg transport unit 55, a container transport unit 51, a transfer unit 57, a dog 50 a and an endless chain 50 b.
In addition, in order to simplify description, the arm 58 of the transfer part 57 is abbreviate | omitted in FIG. 5, and the egg conveyance part 55 and the tray 6 are abbreviate | omitted in FIG.

The egg transport unit 55 transports the eggs E accommodated in the tray 6 partitioned in 5 rows × 6 columns with the long axis vertical, in the egg transport direction. The egg transport unit 55 stops when the tray 6 is transported to the position immediately below the transfer unit 57 (egg adsorption position) indicated by the two-dot chain line in the first and second rows of the tray 6.

Dogs 50a are fixed at equal intervals to the endless chain 50b provided in the container transport section 51, and eight packs are made so that the storage seats 3 of the eight pack containers 2 are arranged in two rows in the container transport direction. The container 2 is conveyed while being pushed by the dog 50a. The container transport unit 51 transports the eight-packed container 2 to the position immediately below the transfer unit 57 (the egg filling position) indicated by the solid line in the storage seat 3 of the eight-packed container 2 and stops.

The transfer unit 57 includes a head 59 to which twelve suction cups 60 for adsorbing and transferring the eggs E are attached, and an arm 58 for driving the head 59.
The transfer part 57 adsorbs 2 rows × 4 columns (8) from the eggs E accommodated in the tray 6 in 5 rows × 6 columns (30) at the position indicated by the two-dot chain line (egg adsorption position). And take it out. Thereafter, the transfer unit 57 moves to a position (egg filling position) indicated by a solid line on the container transport unit 51 and fills the accommodation seat 3 of the eight-packed container 2 with the eggs E.

When the egg E is filled in the storage seat 3 of the eight-packed container 2, the eight-packed container 2 is further transported downstream in the container transport direction. A sealing device such as a tape sealer is provided downstream in the container transport direction, and the lid 4 of the eight-packed container 2 is closed and sealed by the sealing device.

In the case of such a conventional egg wrapping apparatus, only a number corresponding to the containers on the container transport section 51 can be filled per transfer operation by the transfer section 57. For example, when filling the above-described eight-packed container 2 with the egg E, only the eight suckers 60 among the 12 suckers 60 attached to the head 59 of the transfer unit 57 are used. Can adsorb only a maximum of 8 pieces in one transfer operation. When eight eggs are transferred from the tray 6, as shown in FIG. 5, a total of four eggs E are left on the first row and the second row on the tray 6, two each. It is.

Then, the transfer unit 57 that has returned to the egg adsorption position adsorbs the four eggs E remaining in the first and second rows of the tray 6 in the second transfer operation, and moves again to the egg filling position. Since the eggs E must be filled in the storage seat 3 of the eight-packed container 2, the transfer unit 57 has 12 suction cups 60 for transferring all the eggs E stored in the single tray 6. It was necessary to go back and forth between the egg adsorption position and the egg filling position many times using only a part.

In addition, in order to reduce the number of reciprocations of the transfer unit 57, after the eggs of 2 rows × 6 columns (12 pieces) are collectively sucked from the tray 6 and 8 eggs E are filled in the 8 pieces container 2 Even if the remaining eight eggs E are filled in the next eight-packed container 2 sent from the upstream side of the container transport section 51, the position of the transfer section 57 is finely controlled, or the suction cup 60 Need to selectively adsorb and release the egg E.

In order to solve the problems of the conventional egg wrapping apparatus, the eggs transported in a plurality of rows are taken out two rows at a time, and a plurality of container seats are arranged in a two-row column by the container transport unit. What is necessary is just to convey in the state which adjoined the container, and to fill a several container collectively with an egg.
By doing in this way, it is not necessary for the transfer part to reciprocate between the egg adsorption position and the egg filling position many times or to finely control the position of the transfer part, and 12 pieces attached to the transfer part The eggs can be efficiently refilled into a container such as an egg pack made of synthetic resin for shipment, always using the same transfer operation while using all the suction cups.

If the egg packaging device is capable of taking out two rows of eggs transported in multiple rows as described above and filling eggs in a plurality of containers at once, the transfer unit always moves to the container with the same operation. Eggs made of synthetic resin, which is a general egg packaging container, have flanges on the periphery of the main body and lid, so that the seats across the container The space of is wide by the flange.
Then, in the egg wrapping apparatus provided with the conventional container transport unit that transports the container by a dog fixed to the endless chain at a predetermined interval, the twelve-packed container, the ten-packed container, the eight-packed container, and the six-packed container・ Since it was not possible to cope with the difference in intervals such as four-packed containers, it was not possible to produce multi-variety small-lot production that frequently switched various types of containers according to the shipping destination and demand.

The egg wrapping apparatus of the present invention includes a transfer unit that batch-fills eggs taken out from an egg transport unit in 2 rows × N columns into a container seat, and a plurality of containers so that the seat is a two-row longitudinal unit. A container transport unit that transports the containers adjacent to each other, a storage seat detection unit that detects a storage seat of the container transported by the container transport unit, and an egg detection that detects an egg filled in the storage seat detected by the storage seat detection unit And the egg detection unit is configured to stop the container when no egg is detected, so that the storage seat that is not filled with eggs stops at the egg filling position, and the transfer unit is collectively And fill the containment seat with eggs.

The egg wrapping apparatus according to the present invention can fill the eggs in a lump by stopping the accommodation seat of the container not filled with the eggs at an appropriate position. Also, since the containers are not transported by dogs fixed to the endless chain, various types of containers such as twelve-packed containers, ten-packed containers, eight-packed containers, six-packed containers, and four-packed containers are frequently used. It is possible to handle multi-product small lot production.

It is a figure which shows the transfer operation | movement of the egg packaging apparatus which concerns on 1st Example of this invention. It is the figure which looked at the egg packaging apparatus of FIG. 1 from the X direction. It is a figure which shows the state which the egg packing apparatus of FIG. It is a figure which shows the state which the egg packaging apparatus which concerns on 2nd Example of this invention fills with eggs in a four-packing container. It is a figure which shows the transfer operation | movement of the egg packaging apparatus which concerns on a prior art. It is the figure which looked at the egg packaging apparatus of FIG. 5 from the X direction.

Hereinafter, a first embodiment of an egg wrapping apparatus according to the present invention will be specifically described with reference to the drawings.

FIG. 1 is a view showing a transfer operation of an egg wrapping apparatus according to a first embodiment of the present invention, and FIG. 2 is a view of the egg wrapping apparatus according to the first embodiment of the present invention as viewed from the X direction. is there. FIG. 3 is a view showing a state in which the egg wrapping apparatus of FIG. 2 fills eight packed containers with eggs. In addition, in order to simplify description, some structures are abbreviate | omitted in each figure.

As shown in FIG. 1, the egg wrapping apparatus according to the first embodiment of the present invention includes an egg transport unit 5 that transports eggs E accommodated in six rows in the tray 6 in the egg transport direction with the long axis vertical. A plurality of transfer sections 7 that take out the eggs E from the egg transport section 5 in 2 rows and 6 columns, and a plurality of receiving seats 3 for filling the eggs E taken out by the transfer section 7 into a two-row column. A container transport unit 1 that transports the eight packed containers 2 adjacent to each other in the container transport direction, a storage seat detection unit 12 that detects the storage seat 3 of the eight packed containers 2 transported by the container transport unit 1, and a storage And an egg detection unit 11 for detecting an egg E filled in the accommodation seat 3 detected by the seat detection unit 12.

The egg transporting unit 5 is a tray transporting conveyor that transports the trays 6 containing 5 rows × 6 columns (30) of eggs E in the egg transporting direction. The egg transport unit 5 is provided with a sensor, and is configured to detect the sensor and stop the tray 6 when the tray 6 is transported to a predetermined position (egg adsorption position). The egg transport unit 5 can also transport the tray 6 by rotating it 90 degrees horizontally as 6 rows × 5 columns.
Moreover, since the egg conveyance part 5 should just convey the egg E accommodated by making the major axis perpendicular | vertical in the state which arranged in the egg conveyance direction, it is not restricted to the tray conveyance conveyor which conveys the tray 6, One line called a cup It may be a cup conveyor that continuously conveys a plurality of units capable of accommodating six eggs.

The transfer unit 7 has a head 9 to which twelve suction cups 10 made of silicon are attached. The head 9 is attached to an arm 8 of a driving device that drives the transfer unit 7. The transfer part 7 indicated by a two-dot chain line in FIG. 1 represents an egg adsorption position when the egg E is taken out from the tray 6, and the transfer part 7 indicated by a solid line is the egg E taken out from the tray 6. The egg filling position when filling the eight-packed container 2 is shown.

The suction cup 10 attached to the head 9 of the transfer unit 7 is fixed to the head 9 at the same interval as the interval of the eggs E accommodated in the tray 6, and the vacuum piping that communicates the inside of the arm 8 and the head 9. Thus, the egg E can be adsorbed by lowering the pressure inside the suction cup 10. Although the space between the storage seats 3 of the eight-packed container 2 is somewhat different depending on the size of the eggs E to be stored, it can be filled in accordance with the distance between the container storage seats by the elasticity of the suction cups 10, so that this embodiment Then, the suction pad interval is not changed when the egg E is adsorbed and filled.
In particular, even if the filling position is slightly deviated from the center of the storage seat 3, the egg is properly filled in the storage seat 3 according to the shape of the end portion, so that there is no problem even if the suction cup 10 is fixed to the head 9. However, by making it possible to change the interval between the suction cups 10 when the egg E is adsorbed from the tray 6 and when the egg E is filled into the eight-packed container 2, the egg E can be moved without any burden. It can also be posted.

The container transport unit 1 is a container transport conveyor that transports a plurality of eight-packed containers 2 adjacent to each other so that the storage unit 3 of the eight-packed containers 2 is in a two-row column with respect to the container transport direction. There is no dog 50a fixed to the endless chain 50b as in the conventional egg wrapping apparatus shown in FIG. 5 in the container transport unit 1, and the eight-packed container 2 is transported by a transport belt whose slip surface is processed on the transport surface. ing.

The storage seat detection unit 12 is an optical sensor for detecting the storage seat 3 of the eight-packed container 2 transported by the container transport unit 1. The receiving seat detection unit 12 is not limited to an optical sensor, as long as it is a detection device that detects the receiving seats 3 of the plurality of eight-packed containers 2 that are conveyed in an adjacent state. The storage seat detection unit 12 may be any sensor that can detect a storage seat of a transparent synthetic resin container or a paper container called a pulp mold.

The egg detection unit 11 is an optical sensor for detecting whether or not the egg E is filled in the storage seat 3 of the eight-packed container 2 detected by the storage seat detection unit 12. Similarly to the storage seat detection unit 12, any detection device that detects the egg E in the storage seat 3 may be used, and is not limited to an optical sensor.
In the present embodiment, the container seat detection unit 12 and the egg detection unit 11 are described separately, but both may be integrated. In that case, an integrated detection unit is provided above the eight-packed container 2 and at a position that does not interfere with the transfer unit 7, and the egg 3 filled in the container 3 and the container 3 of the eight-packed container 2 below. E may be detected. Further, these detection units are provided with a function of detecting the top of the eight-packed container 2, and the top of the eight-packed container 2 is collectively moved by the transfer unit 7 regardless of the presence or absence of the eggs E filled in the storage seat 3. Then, it may be the top of the storage seat 3 to be filled.

Further, the storage seat detection unit 12 includes a slide mechanism that can change the position upstream or downstream in the container transport direction according to various types of containers.
An egg pack made of synthetic resin, which is a general egg packaging container, has a flange formed on the periphery of the main body and the lid, and when a plurality of containers are transported adjacent to each other, The gap is wide enough for the flange. As the number of flanges increases, the spacing between the storage seats that straddle the container increases, so if you stop the six-packed container or the four-packed container at the same position as the twelve-packed container or the ten-packed container, Egg E spills from the storage seat on the upstream side in the container transport direction, and cannot be filled well. When filling the six-packed container or the four-packed container with the eggs E, the container seat detection unit 12 may be slid downstream in the container transport direction to change the position where the container stops to the downstream.

In addition, an input unit for inputting the type of the container is provided, and the container is set for a predetermined time after the egg detection unit 11 and the storage seat detection unit 12 detect the storage seat 3 and the egg E according to the input container type. If the stop position can be changed by delaying the stop timing, there is no need to provide a slide mechanism.
Furthermore, an identifier such as a bar code may be attached in place of the input unit so that the type of the container can be specified, and the identifier can be read to stop at the optimum position for the container.

As described above, the mechanism and control for changing the stop position of the container provided in the egg wrapping apparatus according to the present invention are collectively referred to as a stop position changing section.

Next, a series of transfer operations by the egg wrapping apparatus according to the first embodiment of the present invention described above will be described.
In order to carry out appropriate production according to the shipping amount, the eggs E sorted by class are temporarily stored in the tray 6 which is a temporary container, and refilled into an eight-packed container 2 for retail stores according to demand. The eggs are transported in the egg transport direction by the egg transport unit 5 while being accommodated in the tray 6. At this time, as shown in FIG. 1, the egg transport unit 5 transports the eggs E stored in the tray 6 divided in 5 rows × 6 columns with the long axis vertical, in the egg transport direction. The second row is controlled to stop immediately below the transfer unit 7 (egg adsorption position) indicated by a two-dot chain line.

When the tray 6 stops at the egg adsorption position, the transfer unit 7 is lowered to a height at which the eggs E accommodated in the tray 6 and the suction cups 10 attached to the head 9 are sufficiently in contact with each other. When the egg E accommodated in the tray 6 and the sucker 10 come into contact with each other, the vacuum pipe communicating the inside of the arm 8 and the head 9 is decompressed by the vacuum pump, and the sucker 10 adsorbs the egg E. The transfer unit 7 moves up while adsorbing the eggs E, and takes out 2 rows × 6 columns (12 pieces) of eggs E accommodated in the first and second rows of the tray 6 from the tray 6.

When the eggs E in the first and second rows are taken out from the tray 6, the egg transport unit 5 transports the tray 6 again in the egg transport direction, and the third and fourth rows of the tray 6 are indicated by two-dot chain lines. The tray 6 is stopped so as to be directly under the transferred portion 7 (egg adsorption position).

The transfer unit 7 that has removed the eggs E from the tray 6 moves to a position (egg filling position) indicated by a solid line on the container transport unit 1 and stops. FIG. 2 shows a state in which the container transport unit 1 and the transfer unit 7 are viewed from the X direction at this time, and the eight-packed containers 2 supplied from the container supply device installed on the upstream side in the container transport direction are: The container seats 3 are transported on the container transport unit in a state of being adjacent to each other so as to form a two-row column in the transport direction.

When the eight-packed container 2 transported on the container transport unit 1 reaches the position immediately below the transfer unit 7 (egg filling position) indicated by the solid line, the housing seat 3 is detected by the housing seat detection unit 12, and at the same time the egg is detected. The egg E filled in the storage seat 3 is detected by the part 11. At this time, if the storage seat 3 detected by the storage seat detection unit 12 is filled with the egg E, the eight-packed container 2 is transported downstream as it is in the container transport direction, but the storage seat 3 is filled with the egg E. If not, the container transport unit 1 stops the eight-packed container 2 in the state shown in FIG.

The transfer unit 7 starts to descend as shown in FIG. 3 to fill the eight-packed container 2 stopped at the egg-filling position as shown in FIG. It descends until it touches.
As described above, the number of eggs E transferred by the transfer unit 7 is twelve, and one eight-packed container 2 cannot receive all twelve eggs E, so two eggs E as shown in FIG. It fills over the above eight packing containers 2.

As described above, when two or more eight-packed containers 2 are filled, the space between the receiving seats 3 of the adjacent eight-packed containers 2 is wide by the flange. The suction cup 10 attached to the head 9 is made of an elastic member such as silicon, and the eight-packed container 2 is not fixed on the container transport unit 1, so the difference in the spacing between the storage seats 3 Thus, even if the filling position of the egg E is slightly deviated, the intended storage seat 3 can be filled by the elasticity of the suction cup 10 and the slight movement of the eight-packed container 2 pushed by the egg E.

When all twelve eggs E come into contact with the storage seat 3, the suction cup 10 is separated from the eggs E, and the filling into the eight-packed container 2 is completed. When the egg E is filled in the eight-packed container 2, the container transport unit 1 starts transporting the eight-packed container 2 again in the container transport direction.

When the transport of the eight-packed container 2 is resumed, the container transport unit 1 transports the eight-packed container 2 in the container transport direction until the storage seat 3 not filled with the egg E reaches the storage seat detection unit 12. to continue. A sealing device such as a tape sealer is provided downstream in the container conveying direction, and the eight-packed container 2 in which the eggs E are filled in all the storage seats 3 is closed and sealed by the sealing device.

The transfer unit 7 in which the filling of the eggs E into the eight-packing container 2 is completed rises and again moves to the position (egg adsorption position) indicated by the two-dot chain line on the egg transport unit 5, The 2 rows × 6 columns (12 pieces) of eggs E contained in the rows and 4 rows are taken out of the tray 6 and a series of operations are repeated.

According to the egg wrapping apparatus according to the first embodiment of the present invention, the transfer unit 7 always adsorbs and takes out the egg E at the same position on the egg transport unit 5 regardless of the type of container, Since the egg E can be filled in the container at the same position on the container transport unit 1 at all times, complicated control is not required, and the processing speed can be increased while simplifying the structure and control of the transfer unit 7. .

In addition, although the present Example demonstrated the operation | movement which transfers the egg E to the 8-pack container 2, the container conveyance part 1 of the egg packaging apparatus which concerns on this invention is an endless chain like the conventional egg packaging apparatus. Since a fixed dog is not used, various types of containers such as twelve-packed containers, ten-packed containers, eight-packed containers, six-packed containers, and four-packed containers can be transported.

Next, a second embodiment of the egg wrapping apparatus of the present invention will be specifically described with reference to the drawings. In the description of the second embodiment, components that are the same as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

FIG. 4 is a view showing a state in which the egg wrapping apparatus according to the second embodiment of the present invention fills the four-packed container 13 with the eggs E all together.
The storage seat detection unit 12 a is an optical sensor for detecting the storage seat 3 of the four-packed container 13 transported by the container transport unit 1. The storage seat detection unit 12a is not limited to an optical sensor, as long as it is a detection device that detects the storage seats 3 of the plurality of four-packed containers 13 that are conveyed in an adjacent state. The housing seat detection unit 12a may be any sensor that can detect the housing seat of a transparent synthetic resin container or a paper container called a pulp mold.

The storage seat detection unit 12 b is an optical sensor for detecting the storage seat 3 of the four-packed container 13 transported by the container transport unit 1 and measuring the interval between the detected storage seats 3. The detection of the storage seat 3 is sent to the control unit by an ON / OFF signal, and the control unit measures the interval of the storage seat 3 from the interval of the ON / OFF signal.

By measuring the interval between the storage seats 3 that have passed through the storage seat detection unit 12b, it is possible to know the interval L from the beginning to the end of the storage seat 3 in which the eggs E are collectively filled by the transfer unit 7. . The storage seat detection unit 12b is not limited to an optical sensor, as long as it is a detection device that detects the storage seats of a plurality of containers conveyed adjacently in the same manner as the storage seat detection unit 12a.

Next, the filling operation by the egg wrapping apparatus according to the second embodiment of the present invention described above will be described.
The transfer part 7 which took out the egg E from the tray 6 like Example 1 moves to the egg filling position on the container conveyance part 1, and stops. The four-packed containers 13 supplied from the container supply device installed on the upstream side in the container transport direction are adjacent to the container transport direction in such a manner that the storage seats 3 are in two rows in the container transport direction. It is transported in the container transport direction.

When the storage seat 3 of the four-packed container 13 passes in front of the storage seat detection unit 12b, an ON / OFF signal corresponding to the presence or absence of the storage seat 3 is sent from the storage seat detection unit 12b to the control unit. The interval L of the storage seat 3 from the beginning to the end where the eggs E are filled is known from the interval of the / OFF signal and the amount of movement of the four-packed container 13 conveyed by the container conveying unit 1.

Further, when the four-packed container 13 transported downstream in the container transport direction reaches the egg filling position, the container seat 3 is detected by the container seat detector 12a, and the eggs E filled in the container seat 3 by the egg detector 11 are detected. Is detected. At this time, if the egg 3 is filled in the container 3 detected by the container detector 12a, the four-packed container 13 is further conveyed downstream in the container conveying direction, but the egg E is filled in the container 3 If not, the egg detection unit 11 sends a signal to the control unit that there is no egg E in the accommodation seat.

The control unit that has received a signal that there is no egg in the receiving seat 3 is such that the center of the interval L from the receiving seat 3 (the top) to the last receiving seat 3 that is filled at once is the head of the transfer portion 7. The stop position of the four-packed container 13 is controlled so as to coincide with the center of the interval M from the head to the tail of the suction cup 10 attached to 9.

The transfer unit 7 starts to descend as shown in FIG. 4 to fill the four-packed container 13 stopped at the egg filling position as shown in FIG. It descends until it touches.
As described above, the number of eggs E transferred by the transfer unit 7 is twelve, and one four-packed container 13 cannot receive all the twelve eggs E, so three as shown in FIG. It fills over the above four-packed containers 13.

When all the twelve eggs E come into contact with the receiving seat 3, the suction cup 10 is separated from the eggs E, and the filling into the four-packed container 13 is completed. When the egg E is filled in the four-packed container 13, the container transport unit 1 starts transporting the four-packed container 13 to the downstream side in the container transport direction again.

When the transport of the four-packed container 13 is resumed, the container transport unit 1 does not stop and continues to transport the four-packed container 13 until the storage seat 3 that is not filled with the egg E reaches the storage seat detection unit 12a. . A sealing device such as a tape sealer is provided downstream in the container transport direction, and the four-packed container 13 in which the eggs E are filled in all the storage seats 3 is closed and sealed by the sealing device.

According to the egg wrapping apparatus according to the second embodiment of the present invention, when the container is switched to another type as in the first embodiment, the container type is input in advance or the container is attached by a barcode attached to the container. It is not necessary to identify the types of containers, and various types of containers can be mixed.
Further, since the interval L from the beginning to the end of the storage seat for filling the eggs E in a lump is known, the center of the interval L becomes the center of the interval M of the suction cups 10 attached to the head 9 of the transfer unit 7. Thus, the position at which the container is stopped can be adjusted, and the egg E can be more accurately filled into the accommodation seat.

Furthermore, in this embodiment, the container detection unit 12b not only measures the interval between the storage seats 3, but also stops the container when the container is transported from the storage seat detection unit 12b by a predetermined distance. The container can be stopped without providing the storage seat detector 12a. In addition, when the space between the containers is large enough to prevent the transfer of the eggs E by the transfer unit 7, the container seat detection unit 12b sends a signal informing the container supply abnormality to the control unit, and the container It is also possible to notify the operator by sounding an alarm notifying the supply abnormality at the same time as the conveyance of the vehicle is stopped.

In addition, the effect described in the Example of this invention only enumerated the most suitable effect resulting from this invention, and the effect by this invention is not limited to what was described in the Example of this invention.
