Description

Egg pack transfer device

The present invention relates to an egg pack transfer device for transferring an egg pack that has been sequentially conveyed to a storage space provided in an egg pack case or a roll inner.

An egg pack boxing device that packs an egg pack in an egg pack case or the like is known. In this type of egg pack boxing device, egg packs corresponding to one stage of the case are arranged in the temporary standby area. Thereafter, the egg packs are packed in the case while maintaining the arrangement relationship of the arranged egg packs.

* There are various sizes and shapes of cases. Also, egg packs come in various sizes and shapes. For this reason, there are a wide variety of combinations of cases and egg packs. An egg pack boxing device is required to cope with such variations. In an egg pack boxing device, in order to cope with variations in the combination of a case and an egg pack, the temporary waiting area is increased, the conveyor disposed upstream of the temporary waiting area is increased, and the egg pack alignment mechanism is increased. It is assumed that complication will occur. Furthermore, it is assumed that the cost increases with the increase in size and complexity. As a patent document disclosing a method of filling an egg pack into an egg pack container, for example, there is Patent Document 1.

As a countermeasure to such a problem, an egg pack boxing apparatus has been developed that packs an egg pack by reducing the number of egg packs to be boxed by one boxing operation to be smaller than the number of egg packs for one stage. In this egg pack boxing device, for example, using a conventional articulated robot whose head part arbitrarily operates, the egg pack housed as one stage in the case is packed twice or three times. It is accommodated by the boxing operation.

Specifically, when the number of egg packs for one stage in the case is five, for example, the egg packs are divided into three egg packs and two egg packs. Three egg packs collected in the temporary waiting area are held in the head portion. The head portion holding the three egg packs moves from the temporary standby area to the case, is released from the holding state, and is accommodated in the case of the three egg packs. The head part released from the holding state moves from the case to the temporary standby area. Next, the two egg packs collected in the temporary waiting area are held in the head portion. The head part holding the two egg packs moves from the temporary standby area to the case, is released from the holding state, and is accommodated in the case of the two egg packs. Thus, the first five egg packs in the case are accommodated in the case. Thereafter, by repeating the same operation, five second-stage egg packs are accommodated on the first-stage egg pack.

An example of an egg pack transfer device according to an embodiment will be described. As shown in FIGS. 1 and 2, the egg pack transfer device 1 transfers a plurality of conveyed egg packs to a predetermined accommodation space A including a case. The egg pack transfer device 1 transfers the egg pack P collected in the temporary standby area 21 to the egg pack accommodation space A. The egg pack transfer device 1 includes a holding unit 11, a head unit 14, a holding release unit 12, a vacuum mechanism 13, and a control unit 3. Here, the accommodation space A in which the egg pack P is accommodated is formed in a box-like case C.

The holding unit 11 holds a plurality of egg packs P. The holding part 11 is configured by a first suction member 15 and a second suction member. The first adsorption member 15 can hold two adjacent egg packs P, for example. The second adsorption member 16 can hold, for example, two egg packs P.

The first suction member 15 and the second suction member 16 are connected to the vacuum mechanism 13. A holding release unit 12 is provided between the first suction member 15 and the second suction member 16 and the vacuum mechanism 13. The holding release unit 12 includes a holding release unit 12a and a holding release unit 12b. In the first suction member 15, the holding state is released by the holding release unit 12 a. In the second suction member 16, the holding state is released by the holding release unit 12b.

Each of the first adsorption member 15 and the second adsorption member 16 has a bellows structure that can be expanded and contracted in the vertical direction. In the state where the egg pack is adsorbed, the first adsorbing member 15 and the second adsorbing member 16 are in a contracted state. On the other hand, in a state where the egg pack is not adsorbed, the first adsorbing member 15 and the second adsorbing member 16 are extended by gravity.

The holding part 11 is attached to the head part 14. The head unit 14 moves between the temporary standby area 21 and the case C. As the head unit 14, a conventional articulated robot that operates arbitrarily, such as a 6-axis vertical articulated robot, is used. In addition, as the head unit 14, various types such as a robot or a device that can arbitrarily move with respect to the X axis, the Y axis, and the Z axis can be adopted.

The egg pack transfer device 1 and the transport device 2 constitute an egg pack transfer system 10. The conveyance device 2 is, for example, a belt conveyor. A temporary standby area 21 is provided on the downstream side of the transport device 2. A packaging device (not shown) for storing eggs in a pack is disposed on the upstream side of the transport device 2.

The egg pack in which the eggs are contained in the pack by the packaging device is transported to the temporary standby area 21 by the transport device 2. The temporary standby area 21 is provided with a stopper 22 that restricts the movement of the egg pack. In a state where the predetermined number of set egg packs are gathered in the temporary standby area 21, the conveying device 2 is temporarily stopped and the egg pack transfer operation is started. This work (operation) will be described later.

The operation of the egg pack transfer device 1 is controlled by the control unit 3. The control unit 3 controls the holding state and movement of the egg pack P held by the holding unit 11. The control unit 3 performs control so that one egg pack P and the other egg pack P among the plurality of egg packs P held by the holding unit 11 are separately released. The control unit 3 controls so that the state of holding another egg pack P is released after the state of holding one egg pack P is released. The controller 3 controls the movement of the other egg pack P after releasing the state of holding one egg pack P and before releasing the state of holding another egg pack P.

The control unit 3 controls the other egg pack P to be placed at a height position different from the one egg pack P previously placed in the case C. The control unit 3 performs an operation of placing one egg pack on the upper side S1 of the step S formed by the egg pack P already accommodated in the accommodation space A, and then on the lower side S2 of the step S. It controls so that the operation | movement which mounts another egg pack P is performed.

Next, the head part 14 descends, the first suction member 15 contacts two egg packs P of the four egg packs P, and the second suction member 16 contacts the remaining two egg packs P. Contact. Next, the vacuum mechanism 13 is operated. The vacuum mechanism 13 causes each of the first suction member 15 and the second suction member 16 to start evacuation. Four egg packs P are held by the holding unit 11.

Next, the holding unit 11 holding the egg pack P moves from the temporary standby area 21 to above the case C. Next, the head part 14 descends, and, for example, at the position where the two egg packs P held by the first suction member 15 are placed along the first side wall C1 of the case C, the holding release part 12 is placed. To work. The evacuation is stopped by the holding release unit 12. The suction states of the first suction member 15 and the second suction member 16 are released, and the first four egg packs P are accommodated in the case C. Case C shown in FIG. 3 shows two egg packs P on the front side.

The holding unit 11 that has opened the egg pack P moves from the case C to the temporary standby area 21. For example, in a state where four egg packs P are gathered in the temporary standby region 21, the holding unit 11 is lowered, the first suction member 15 comes into contact with the two egg packs P, and the second suction member 16 is Contact the remaining two egg packs P. Next, the vacuum mechanism 13 causes each of the first suction member 15 and the second suction member 16 to start evacuation, and the four egg packs P are held by the holding unit 11.

Next, as shown in FIG. 4, the holding unit 11 holding the egg pack P moves from the temporary standby area 21 to above the case C. Next, the head unit 14 is lowered. At the position where the two egg packs P held by the first suction member 15 are placed along the first side wall C1, the holding release unit 12a of the holding release unit 12 is operated. The suction state of the first suction member 15 is released by the holding release unit 12a, and two more egg packs P are accommodated along the first side wall C1 on the egg pack P accommodated first. In other words, two more egg packs P are placed on the upper side S1 of the step S formed by the egg pack P accommodated first.

Next, as shown in FIG. 5, the holding unit 11 holding the remaining two egg packs P moves to above the region S3 in the case C where the egg packs P are not yet placed. At the position where the two egg packs P held by the second suction member 16 are placed along the second side wall C2, the holding release unit 12b of the holding release unit 12 is operated. The suction state of the second suction member is released by the holding release unit 12b, and the two egg packs P are placed in the region S3 in the case C. In other words, the two egg packs P are placed on the lower side S2 of the step S formed by the egg packs P already accommodated in the case C.

Next, as shown in FIG. 6, the holding unit 11 holding the egg pack P moves from the temporary standby area 21 to above the case C. Next, the head unit 14 is lowered. The holding release unit 12 is operated at a position where the two egg packs P held by the second suction member 16 are placed along the second side wall C2. The evacuation is stopped by the holding release unit 12. The suction states of the first suction member 15 and the second suction member 16 are released, and the four egg packs P are placed on top of the four egg packs P that are already placed. In other words, the four egg packs P are placed in the region S4 in the case C where the second-stage egg pack P is not yet placed. After the transfer operation of the egg pack into the case C is completed, the holding unit 11 moves from the case C to the temporary standby area 21.

The egg pack transfer device 1 according to the present embodiment includes a holding unit 11, a head unit 14, a holding release unit 12, a vacuum mechanism 13, and a control unit 3, and accommodates the egg pack P collected in the temporary standby area 21. Transferred to case C as space A. When transferring the egg pack P to the case C, one egg is placed on the upper side S1 of the step S formed by the egg pack P already accommodated in the case C during one transfer operation. An operation of placing the pack and an operation of placing the egg pack P on the lower side S2 of the step S are performed.

Thereby, compared with the conventional egg packing boxing device, in the operation of storing the egg pack P in the case C, the number of times the head portion reciprocates between the temporary standby area and the case can be reduced. The number of egg packs that can be accommodated in the case C in time can be increased. In the conventional egg pack boxing apparatus, when the egg pack P is to be accommodated in the case C in the steps corresponding to the steps shown in FIG. 3 to FIG. On the other hand, in the egg pack transfer device 1 according to the embodiment, the head unit 14 reciprocates between the temporary standby region 21 and the case C three times so that the egg pack is placed in the case C. P can be accommodated.

Furthermore, compared with the conventional egg packing boxing device, it is possible to cope with various variations without enlarging the temporary waiting area 21 or the conveying device 2 arranged on the upstream side, and the usable space is limited. It can be suitably used for many egg packaging facilities.

Further, the holding unit 11 is a plurality of first suction members 15 and second suction members 16 connected to the vacuum mechanism 13, respectively, and sucks the egg pack P from above. Therefore, as compared with the holding portion that holds the egg pack P from the lower side or the side, the holding portion 11 is provided on the egg pack P that is already accommodated in the case C, the first side wall C1, or the second side wall C2 of the case C. It becomes difficult to interfere.

Of the holding release units 12, the holding release unit 12a operates at a position where one egg pack P held by the first suction member 15 is placed along the first side wall C1, so that one egg The state holding the pack is released. Of the holding release units 12, the holding release unit 12b operates at a position at which the other egg pack P held by the second suction member 16 is placed along the second side wall C2, so that other eggs The state holding the pack is released. Thereby, the egg pack P will be arrange | positioned along the 1st side wall C1 or the 2nd side wall C2 of case C, respectively, and positioning of the egg pack P becomes easy.
