[0011] An embodiment of the egg container transfer system will be described below with reference to FIGS. 1 to 6. In addition, in each drawing, the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios. Furthermore, the dimensional ratios between the drawings do not necessarily match.

[0012] As shown in FIG. 1, the egg container transfer system 1 according to this embodiment supplies and transfers egg containers 2. an egg container transport conveyor 3 for transporting egg containers 2 to a predetermined position; an egg container transfer device 4 for transferring egg containers 2 to a predetermined position; a conveying push unit (5) that pushes the egg containers (2) on the container conveyor (3) onto an egg container transfer device (4); A container transporter transports the container 6 that contains the egg containers 2 to a loading position X1 where the egg containers 2 are loaded. a container discharge unit 8 that moves the container 6 loaded with the egg containers 2 from the loading position X1; An evacuation unit 13 for evacuating the egg containers 2, and an input unit (not shown) for inputting the loading pattern of the egg containers 2. (not included) and

[0013] The egg container 2 has ears 2a (see FIG. 2) that close the hinged lid to prevent the egg container 2 from opening. In this application, the egg container 2 refers to a general container filled with eggs (not shown). The egg container 2 has a concave and convex shape at the bottom to match the shape of the egg, and a flat shape at the top to match the shape of the egg. The number of eggs that can be packed into the egg container 2 (4, 6, 10, The size of the egg container 2 varies depending on the size of the eggs (SS size to LL size). The size of the egg container 2 varies depending on the size of the egg container. can be used with egg container 2, which contains 10 eggs (SS size to LL size). However, Without being limited thereto, the egg container 2 may contain 4, 6, or 12 eggs.

[0014] In this embodiment, the storage unit 6 is a four-tiered general rack (see FIGS. 5 and 6). The loading width is 580 mm and the height of each step is 270 mm, but this is not limited to these. The egg containers 2 are loaded on the racks that are the containers 6 and transported to each delivery store. This eliminates the need to display products on shelves (they can be sold while still loaded on racks). This eliminates the need to display the egg containers 2, thereby reducing labor costs.

[0015] The egg container transport conveyor 3 is a belt conveyor, and carries egg containers that have been sorted by egg size upstream. 2 (for example, L size) is transported downstream in the forward and backward direction D2 with the shorter side of the egg container 2 at the front. However, the present invention is not limited to this. For example, different egg sizes (e.g. The egg containers 2 may be transported in sizes L and M.

[0016] The egg container transfer device 4 includes an aligning conveyor 9 for aligning the egg containers 2 and a hand and an aligning push unit 1 which pushes the egg containers 2 on the aligning conveyor 9 onto the hand unit 10. 1, and a hand unit 10 attached to the tip thereof, which transfers the hand unit 10 to a predetermined position. and a transfer section 12.

[0017] As shown in FIG. 2, the aligning conveyor 9 is a conveyor belt 9 on which the egg containers 2 are aligned and placed. a, a belt drive unit 9b that drives the conveyor belt, and a bell that controls the belt drive unit 9b. In this embodiment, the alignment conveyor 9 has six A belt conveyor that can arrange egg containers 2 in the short direction, but is not limited to this. isn't it.

[0018] The aligning conveyor 9 is disposed at a lower position than the egg container transport conveyor 3. In this state, the conveyor step H1 between the aligning conveyor 9 and the egg container transport conveyor 3 is 5 mm, but is not limited to this. In the case of the size or more, the ear part 2a of the egg container 2 placed on the aligning conveyor 9 first is transferred to the ear part 2a of the egg container 2 placed on the aligning conveyor 9 later. The ears 2a of the egg containers 2 placed on the tray can be overlapped. The container 6 can be compactly loaded, and more egg containers 2 can be loaded in the container 6. It is possible.

[0019] The conveyor belt 9a is oriented in a direction perpendicular to the conveying direction (left-right direction D1) of the conveyor belt 9a. The first projections 90a are provided along the front-rear direction D2. The first protrusion 90a is aligned in the direction perpendicular to the conveyor belt. However, the present invention is not limited to this. For example, the first protrusion 90 a is formed by a plurality of convex portions along the above-mentioned orthogonal directions, and It may be provided around the entire outer periphery.

[0020] The interval between adjacent first protrusions 90a is a constant first protrusion pitch P1. In this embodiment, the first convex portion pitch P1 is 48 mm, but is not limited to this. As a result, the concave portion of the uneven shape at the bottom of the egg container 2 fits into the first convex portion 90a, This prevents the egg containers 2 from slipping on the conveyor belt 9a.

[0021] The conveyor belt 9a rotates in the conveying direction (left-right direction D1) by one pitch (first convex portion pitch). The belt control unit controls the egg containers 2 in units of P1. For example, after placing an egg container 2 on the conveyor belt 9a, before the next egg container 2 is placed on the conveyor belt 9a, The conveyor belt 9a rotates by two pitches, and the egg containers 2 are aligned with a space between them. When queuing, for example, after an egg container 2 is placed on the conveyor belt 9a, the next egg container 2 is placed on the conveyor belt 9b. Before being rotated, the conveyor belt 9a is rotated three pitches.

[0022] As shown in FIG. 3, the hand unit 10 includes a lower plate 10a on which the egg container 2 is placed, and The upper plate portion 10b is arranged with a space provided above the upper plate portion 10a for placing the egg container 2 thereon, and the lower plate portion 10a is arranged with a space provided above the upper plate portion 10b for placing the egg container 2 thereon. The upper plate portion 10b is parallel to the plate drive portion 10a and moves the plate drive portion 10b in one direction relative to the egg container 2. In this embodiment, the upper plate portion 10b and the plate driving portion 10c are The lower plate 10a is attached to the plate driving unit 10c. Here, one direction of the egg container 2 is the longitudinal direction or the lateral direction of the egg container 2. This refers to the direction parallel or perpendicular to the direction in which the hinged lid is opened.

[0023] As shown in FIG. 4, the lower plate portion 10a is spaced apart from the first protrusions 90a at the same intervals as the intervals between the adjacent first protrusions 90a. A plurality of second protrusions 100a are provided in parallel to the longitudinal direction of the first protrusion 90a, and a plate driving unit 10c and a lower plate mounting portion 101a (see FIG. 3) that is mounted on the lower plate.

[0024] The interval between adjacent second protrusions 100a is a constant second protrusion pitch P2. In the embodiment, the first convex portion pitch P1 and the second convex portion pitch P2 are the same interval. The same interval means substantially the same interval with a maximum deviation of 5 mm. With this configuration, the concave portion of the concave-convex shape at the bottom of the egg container 2 is the second convex portion 100. a, and the egg container 2 on the lower plate portion 10a can be prevented from slipping. The transfer device 4 can load the egg containers 2 while maintaining the egg containers 2 aligned in the container 6. 4(a) shows six egg containers 2 stacked, and FIG. 4(b) shows five egg containers 2 stacked. This is an example of a stacked state.

[0025] As shown in FIG. 3, the upper plate portion 10b is located above the egg container 2 placed on the lower plate portion 10a. Upper plate main body portion 100b and plate drive portion 10c move the lower plate portion 10a and the upper plate portion 10b relative to each other. At this time, the egg container 2 placed on the lower plate portion 10a is moved away from the lower plate portion 10a. 2 at least on the side (opposite side in the front-rear direction D2), and a hand transfer unit 12, and an upper plate mounting portion 102b for mounting to the upper plate mounting portion 102b.

[0026] In this embodiment, the plate driving unit 10c drives the lower plate portion 10a to the opposite side in the front-rear direction D2. At this time, the pushing portion 101b and the upper plate main body portion 100b are moved in accordance with the movement of the lower plate portion 10a. The movement of the egg container 2 in the lateral direction (opposite the front-back direction D2) and upward direction (up-down direction D3) is controlled without being linked to the Limited.

[0027] In this embodiment, the extrusion portion 101b and the upper plate main body portion 100b are flat plates. For example, the upper plate main body portion 100b has a longitudinal direction that is the left-right direction D1. The support may be made up of a plurality of rod-shaped members arranged in a line.

[0028] In this embodiment, the pushing portion 101b is connected to the upper plate main body portion 100b. For example, it may be connected to the upper plate mounting portion 102b, The position of the extrusion section 101b in the front-rear direction D2 may be adjusted. By adjusting the size of the egg container, egg containers 2 containing 4, 6, or 12 eggs can also be moved by the egg container transfer device 4. This can be done.

[0029] The plate driving unit 10c includes a plate driving main body 100c attached to the hand transport unit 12 and a lower plate mounting a plate moving section 101c which is attached with a plate driving main body section 100c and is moved by the plate driving main body section 100c; In this embodiment, the plate driving unit 10c is an air cylinder, but is not limited to this. It is not something that can be done.

[0030] As shown in FIG. 3(a), the lower plate portion 10a is moved by the plate driving portion 10c to the hand transfer portion 10b. When the egg container 2 is moved to the side of the lower plate portion 10a, the egg container 2 placed on the lower plate portion 10a also moves together with the lower plate portion 10a. Then, as shown in FIG. 3(b), when the egg container 2 hits the pushing part 101b, the egg container 2 is pushed downward. The egg container 2 cannot move any further together with the plate portion 10a and slides on the lower plate portion 10a. The portion of the egg container 2 that rests on the lower plate portion 10a decreases, and the egg container 2 is lowered into the container body 6 at an egg container angle α. This allows the egg container 2 to be attached to the lower plate even in a container 6 that has a height restriction, for example. It can be removed from the section 10a.

[0031] Here, when the egg container 2 is lowered, the upper plate main body part 100b comes into contact with the upper end of the egg container 2. As a result, the egg container angle α can be reduced. This improves the accuracy of lowering at the target position.

[0032] In the case of egg containers 2 with an uneven upper portion, the egg containers 2 are stacked on top of the egg containers 2 previously loaded in the container 6. The concave portion of the first egg container is fitted into the convex portion of the second egg container. By setting the container angle α, it becomes easy to fit the convex portion at the tip of the egg container 2 into the concave portion. In addition, since the concave and convex parts are inclined, they are within ±15 mm from the center of each part. If the offset is on the inside, the convex portion and the concave portion can be fitted together along their respective inclinations.

[0033] As shown in FIG. 1, the hand transfer unit 12 is attached to the floor and is movable in the left-right direction D1. The first slide portion 12a and the movable portion (not shown) of the first slide portion 12a are attached to each other. The second slide portion 12b is movable in the up-down direction D3, and the movable portion of the second slide portion 12b (see FIG. a third slide portion 12c attached to a slide member (not shown) and movable in the front-rear direction D2; The slide control unit (not shown) controls the movement of the portions 12a to 12c. In the above, the slide sections 12a to 12c are electrically operated sliders made of aluminum. It is not something that is determined.

[0034] The third slide portion 12c is a first mounting portion (not shown) for mounting the upper plate mounting portion 102b. and a second mounting portion (not shown) to which the plate driving main body portion 100c is attached. As a result, the hand transport unit 12 can move the hand unit 10 to a predetermined position in three dimensions. The predetermined position is a replenishing position X2 where egg containers 2 on the aligning conveyor 9 are placed on the hand unit 10. a plurality of egg container loading positions X11 for loading egg containers 2 onto the containers 6 at the loading positions X1; do.

[0035] The replenishing position X2 is a height between the aligning conveyor 9 and the lower plate portion 10a (see FIG. 3) where the egg containers 2 are placed. The heights (vertical direction D3) of the first protrusion 90a and the second protrusion 100a are the same when viewed from above (upper However, this is not limited to this, and examples include For example, the height of the lower plate portion 10a may be about 10 mm lower than the height of the alignment conveyor 9. The surface of the plate portion 10a is not parallel, but is oriented in the direction in which it is pushed by the alignment push portion 11. The conveyor 9 may be inclined downward by about 10 degrees. is a maximum of 20 mm.

[0036] The egg container loading position X11 is determined by the egg container 2 loading pattern input to the input section. The position of the feeding unit 12 is determined. For example, as shown in FIG. 5, the initial egg container loading position X11 is The egg container loading position X11 is located at the back side (front-rear direction D2) of the first stage of the container 6. The egg containers 2 are moved to the upper side of the back of the first stage of the container 6 until the number of stages of the egg containers 2 in the loading pattern is reached. When the number of egg containers 2 in the loading pattern is reached, the egg container loading position X11 is moved to one of the containers 6. It changes to the front side of the step (opposite side in the front-to-back direction D2) and then changes upward again.

[0037] In this way, the egg containers 2 are stacked in accordance with the stacking pattern until they reach the top of the container 6. The container loading position X11 changes position in the front-back direction D2 and the up-down direction D3. Thus, the egg container transfer system 1 can automatically load the egg containers 2 into the containers 6. This allows the egg containers 2 to be accurately loaded into the container 6 using different loading methods depending on the store. It is possible.

[0038] When the top of the egg container 2 is uneven, the loading pattern is, for example, as shown in FIG. Each row has 6, 5, 6, 5, 6, 4 egg containers 2 from the bottom (opposite side of the vertical direction D3). In a tier with five egg containers 2, there is one pitch (first convex) between the egg containers 2. There is a gap of a pitch P1 between the egg containers 2. This allows the force to be released, preventing the eggs in the egg container 2 from cracking. For example, it is possible to prevent the loaded egg containers 2 from collapsing. However, this is not limited to this. When the top of the egg container 2 is flat, the egg container 2 may be loaded by first loading the egg container 2. The next egg container 2 is loaded directly above the container 2.

[0039] As shown in FIG. 1, at the replenishing position X2, the first protrusion 90a (see FIG. 2) is located on the extension of the first protrusion 90a. When the two protrusions 100a (see FIG. 4) are arranged, the aligning push unit 11 handles the egg container 2. By pushing the sheet toward the lower plate portion 10, it can be transferred from the aligning conveyor 9 to the lower plate portion 10a.

[0040] The transport push unit 5 pushes the egg containers 2 onto the aligning conveyor 9, and then transports them to the egg container transport conveyor. Transporting the next egg container 2 transported by the carrier 3 and the part of the transport push unit 5 that pushes the egg container 2 The present embodiment is provided with a retraction means (not shown) for avoiding contact in the forward and backward direction D2. The retracting means retracts the part of the conveying push unit 5 that pushes the egg container 2 in the vertical direction D3. However, it is not limited to this.

[0041] The container transport unit 7 includes a plurality of container transport conveyors that transport the containers 6 to the claw insertion position X3. 7a, and the container 6 transported from the container transport conveyor 7a is moved from the claw insertion position X3 to the loading position and a first container transfer section 7b for transferring the plurality of containers to X1. The body transport conveyor 7a has a rotation axis in the vertical direction D3 and is configured to sandwich the container 6 in the left-right direction D1. Two units are placed in the forward and backward direction D1, and two more units are placed in the forward and backward direction D2, but this is not limited to this. In addition, when changing the size of the container 6, the setting of the left and right direction D1 of the container transport conveyor 7a is This can be accommodated by changing the placement.

[0042] The first container transfer section 7b has a first hook section 70b having a hook for hooking the container 6, and a first hook a first claw moving portion 71b that moves the first claw portion 70b in the left-right direction D1; and a first claw slide portion 72b that moves the first claw slide portion 71b in the front-rear direction D2.

[0043] By inserting the claw of the first claw portion 70b into the container 6 at the claw insertion position X3, the first claw portion 70 The claw of the first claw slide portion 72b is caught on a part of the container 6, and the container 6 is moved by the movement of the first claw slide portion 72b. After the container 6 is transported to the loading position X1, When the first claw portion 70b is removed from the housing 6, the first claw slide portion 72b is at the claw insertion position X3. Move to.

[0044] The container discharge unit 8 moves the container 6 loaded with the egg containers 2 from the loading position X1 to the discharge position X4. and a second container transfer section 8a that transfers the container 6 at the discharge position X4. and a plurality of pushers for discharging the container 6 pushed out by the container pushing section 8b in the front-rear direction D2. In this embodiment, the plurality of container discharge conveyors 8c are provided. The gears 8c have a rotation axis in the vertical direction D3, and two gears are arranged so as to sandwich the container 6 in the horizontal direction D1. However, the present invention is not limited to this. When changing the size of the housing body 6, This can be accommodated by changing the installation position of the body discharge conveyor 8c in the left-right direction D1.

[0045] The second container transfer section 8a has a second claw section 80a having a claw for hooking the container 6, and a second claw a second claw moving portion 81a that moves the second claw portion 80a in the front-rear direction D2; and a second claw slide portion 82a that moves the first claw slide portion 81a in the left-right direction D1.

[0046] At the loading position X1, the claws of the second claw portion 80a are inserted into the container 6, and the second claw portion 80a The claws are caught on a part of the container 6, and the container 6 is moved by the movement of the second claw slide portion 82a. After the container 6 is transported to the discharge position X4, the second The claw slide portion 82a can be moved up to the loading position X1 when the second claw portion 80a is removed from the container 6. With this configuration, the egg container transfer system 1 automatically replaces the containers 6. As a result, for example, the egg container transfer system 1 can accommodate a plurality of egg containers 2. It can be automatically loaded onto body 6.

[0047] In this embodiment, the egg container transport system 1 moves one egg container 2 per second onto the aligning conveyor. 9. After the egg containers 2 at the loading position X1 are loaded, the container 6 is emptied in 5 seconds. The container 6 can be replaced with another container, but is not limited to this.

[0048] As described above, the egg container transfer device 4 includes an aligning conveyor 9 for aligning the egg containers 2 and a conveyor 3 for carrying the egg containers 2. The hand unit 10 has a lower plate 10a that holds the egg containers 2 on the aligning conveyor 9, and the hand unit 10 pushes the egg containers 2 on the aligning conveyor 9.
