CONSTITUTION:In the case of palletizing cases 5, a case placing base 13 is fitted into a height position between a sweeper frame 12 and a bulk placing base 11, then a transfer device 6 is brought to correspond to a case carry-in line 4, and the cases 5 placed in the tight rectangular aligned state on the case carry-in line 4 are carried in so as to be placed on the case placing base by the sweeper frame 12. After transferring these cases 5 together with the sweeper frame 12 onto a pallet 8 disposed on a downstream carry-out line 7, only the case placing base is returned into the original upstream position. The sweeper frame 12 is then returned into the original upstream position to transfer the following aligned cases onto the case placing base, and then the cases are transferred downstream and stacked on the previous case group.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case and bulk palletizer, and more particularly to a case and bulk palletizer provided with a transfer device configured to be vertically movable so as to correspond to a case loading line and a bulk loading line. Regarding palletizer.

[0002]

2. Description of the Related Art In recent years, containers such as bottles and cans used in the sake brewing industry, soft drink manufacturing industry, chemical industry or canning industry, that is, bulk products as final products, are those arranged on a pallet. In many cases, the products are shipped in a pallet stacking method in which sheets such as corrugated paper and thin plastic plates are stacked in between and packed with strings, rubber bands or shrink films, and such stacking work is performed automatically. A palletizer is used for this purpose.

The palletizer is disposed between the bulk carry-in line and the carry-out line, aligns the bulk carried in by the bulk carry-in line, and transfers the bulk to the downstream side, which is arranged in the carry-out line as described above. It is widely used to stack the pallets in an aligned state on the pallet.

Although not shown in the drawings, such a conventional palletizer has a rectangular outer frame attached to a support bracket configured to be movable in the vertical and horizontal directions. A transfer device having a cross-shaped inner frame configured to be expandable and contractible by
The transfer device is configured to transfer the bulk products carried in the loose state in a square-shaped aligned state onto the pallet. For example, Japanese Patent Publication No. 63-11249
The publication describes an example of such a palletizer.

[0005]

Incidentally, depending on the factory, there are cases where the final product is packed in a case such as a cardboard box or a plastic case and shipped in addition to the bulk product as described above. In such a case, They were stacked on a pallet by a case-only palletizer.

However, when the space in the factory is limited, it may be difficult to provide a bulk loading line and a case loading line separately. Therefore, one palletizer can be used for both bulk loading and case loading. Is desirable.

However, the conventional palletizer cannot be used for both the case and the bulk. When stacking bulks, as described above, sheets such as corrugated cardboard and plastic thin plates are stacked between each row, but in the case of such cases, such sheets are not necessary and the cases are directly connected to each other. This is because the transfer devices are generally different in structure from each other.

The present invention has been made in view of such circumstances.
It is an object of the present invention to provide a palletizer which can be used as a bulk and a case and can be used for palletizing the bulk and the case.

[0009]

The present invention comprises means for achieving the above object as follows. That is, a transfer device that can move up and down is provided so as to correspond to the case loading line and the bulk loading line that are arranged above and below, and the transfer device loads the case into the case loading line and the pre-aligned case or the bulk loading line. The bulk carried in by the line and pre-aligned is aligned more tightly and transferred to the downstream side,
There is a case and bulk palletizer that can be stacked in an aligned state on a pallet on the unloading line.
The transfer device is vertically movable along a vertical guide column and extends horizontally along the guide rail, and is vertically moved together with the guide rail between the bulk loading line and the unloading line so that the bulk can be loaded and loaded on both lines. A bulk platform for transferring, a sweeper frame disposed above the bulk platform and horizontally moving along the guide rails to tightly align the case or the bulk in a square shape, the sweeper frame, and the sweeper frame. It is arranged between the bulk mount and a case in an aligned state mounted on the bulk mount and horizontally moved to the downstream side together with the sweeper frame, and itself can return to the upstream side away from the sweeper frame. It is characterized by having a detachable case stand.

[0010]

[Function] For example, when palletizing bulks,
It is sufficient to operate the case platform without attaching it to the transfer device.First, the transfer device is made to correspond to the bulk loading line, and the bulk is placed on the bulk loading line in a tight rectangular array on the bulk loading line using the sweeper frame. After loading and loading onto the pallet placed on the unloading line on the downstream side together with the sweeper frame, the sweeper frame is returned to its original position and the next time the sweeper frame is used. After aligning and transferring to the downstream side, on the bulk already loaded on the pallet in an aligned state, a sheet is separately placed on the sheet by a separately arranged sheet feeding device, and a new sheet is newly placed on the sheet. The same stacking work is repeated by the sequential sweeper frame so that the aligned bulks are stacked. Meanwhile, the bulk mount and the sweeper frame are adapted to the bulk stack height while appropriately changing the height. In other words, since the bulk platform and the guide rail that guides the sweeper frame are configured to be able to move up and down along the vertical guide column, both the bulk platform and the sweeper frame are at the height position of the carry-in line and the carry-out line. The stacking work can be carried out continuously corresponding to the stacking height of the bulk that changes on the pallet on the line.

On the other hand, when cases are to be stacked on a pallet, it is sufficient to mount and operate the case platform at a height position between the sweeper frame and the bulk platform. First, make the transfer device correspond to the case loading line. That is, the case loading table is made to correspond to the case loading line, and the case in which a tight rectangular shape is aligned on the case loading line by the sweeper frame is loaded and loaded on the case loading table, and then the case loading is carried out. After being transferred together with the sweeper frame onto the pallet arranged on the unloading line on the downstream side, only the case mounting table is returned to the original upstream position. At this time, the aligned case groups are directly seated on the pallet. Then, after returning the sweeper frame to the original position on the upstream side and performing the next alignment, the case is moved to the case stand and then moved to the downstream side, and the case is already loaded on the pallet in an aligned state. Similar stacking work is repeatedly performed by the sweeper frame and the case mount so that a new group of cases in an aligned state is stacked on the group.

As described above, the palletizing of either the case or the bulk can be arbitrarily selected and carried out by a simple operation of simply attaching and detaching the case mount to the transfer device.

Describing the transfer device 6, reference numeral 10 in FIG. 2 indicates that the transfer device 6 can be moved up and down along vertical guide columns 9 and 9 standing upright between the carry-in lines 2 and 4 and the carry-out line 7. 11 is a guide rail that extends horizontally.
It is a bulk loading table that is located between the bulk loading line 2 and the unloading line 7 and that moves up and down together with the guide rail 10 to load and transfer the bulk 3. Reference numeral 12 denotes a sweeper frame which is disposed above the bulk mounting table 11 and horizontally moves along the guide rail 10 to align the bulk 3 or the cases 5, ... In a square shape. A case table 13 is provided between the table 11 and the table rail 10 so as to be movable in the horizontal direction and detachably along horizontal guide frames 14 integrated with the guide rails 10, and the case table 13 is aligned. Further, the cases 5, ... Are mounted and moved to the downstream side together with the sweeper frame 12, and the case itself is separated from the sweeper frame 12 and slidably returned to the original position on the upstream side.

According to this structure, for example, when the bulks 3 are stacked on the pallets, it is sufficient to operate the case mounting table 13 without attaching it to the transfer device 6. First, the transfer device 6 is loaded into the bulk loading line 2. Corresponding to, the bulk 3 which is in a tight rectangular alignment state on the bulk loading line 2 by the sweeper frame 12 is loaded and loaded on the bulk loading table 11, and then the bulk 3 is placed on the downstream side together with the sweeper frame 12. After being transferred onto the pallet 8 arranged on the carry-out line 7, the sweeper frame 12 is returned to its original position, and after the sweeper frame 12 is aligned next time, it is transferred to the downstream side, while The sheet 16 is placed on the bulk 3 placed on the pallet 8 in an aligned state by the sheet feeding device 15 arranged near the transfer device 6. , A sequential sweeper frame so that the newly aligned bulks 3 are stacked on the sheet 16.
The same stacking work is repeated by 12.
Meanwhile, the bulk mount 11 and the sweeper frame 12 correspond to the stacking height of the bulk 3 while appropriately changing the height. That is,
Guide rail 10 for guiding the bulk carrier 11 and the sweeper frame 12
Since the and are configured to be vertically movable along the vertical guide columns 9, 9, both the bulk mount 11 and the sweeper frame 12 are at the height position of the carry-in line 2 and the pallet 8 on the carry-out line 7. The stacking work can be continuously performed in correspondence with the stacking height of the bulk 3 which changes above.

On the other hand, when the cases 5, ... Are stacked on the pallet, the case mounting table 13 may be attached and operated at a height position between the sweeper frame 12 and the bulk mounting table 11. First, the transfer device 6 Corresponds to the case loading line 4, that is, the case loading line 4 is associated with the case loading table 13, and the case 5 is placed on the case loading line 4 by the sweeper frame 12 in a tight rectangular alignment state. Stand
It is loaded on board 13 and is then placed on its sweeper frame 12
Together with the pallet 8 arranged on the unloading line 7 on the downstream side
Then, the case table 13 alone is returned to the original upstream position. At this time, the aligned case groups sit on the pallet 8 as they are. And the sweeper frame
12 is returned to its original position on the upstream side, the next alignment is performed on the case platform 13 and then transferred to the downstream side, and a new one is placed on the case group already mounted on the pallet 8 in an aligned state. Similar stacking work is repeatedly performed by the sweeper frame 12 and the case mounting table 13 so that the case groups in various aligned states are stacked.

As described above, the palletizing of any of the cases 5, ... And the bulk 3 can be arbitrarily selected and performed by a simple operation of simply attaching and detaching the case mounting table 13 to and from the transfer device 6. Therefore, the bulk carrying-in line 2 and the case carrying-in line 4 can be arranged vertically without increasing the floor area to make the apparatus compact and improve the degree of freedom of layout in the factory, and it is necessary for capital investment. It can also save a lot of cost. Further, as will be described in detail later, since the cases 5, ... Can be tightened in an aligned state by the sweeper frame 12 in the same manner as the bulk 3, the stacked packing appearance is improved, especially in the case of a plastic case. The inlay can be securely fitted, and can be shipped in a stable state. Moreover, since the case loading line 4 is provided with a driving function so that the direction of each case 5 can be set appropriately, the state of the load can be stabilized and the load can be prevented from falling.

The pallets 8 thus prepared are supplied to the entrance end of the carry-out line 7 one by one at an appropriate timing.

In the bulk loading line 2 (see FIGS. 1 and 10), the bulks 3 arranged in a predetermined amount for one layer are sequentially gathered by the bin stopper 68a incorporated in the bin stopper frame 68, and are collected on the bin collecting conveyor 69. In this way, a predetermined number of rows are aligned in a rectangular shape in advance. On the other hand, bulk mount
11 is adjusted to the height of the bin collecting conveyor 69, the sweeper frame 12 is moved to surround the bulk 3 arranged in a pre-aligned state on the bin collecting conveyor 69, and the movable plates 45 and 46 are contracted. Move it to make the alignment state tighter and transfer it to the bulk mount 11 [Fig. 12].
(See (A)]. Next, the bulk loading table 11 is placed on the pallet 8
After moving to the height position of the sheet 16 placed on (or already transferred bulk 3), the sweeper frame 12 is moved onto the sheet 16 (see FIG. 12 (B)). In this state, the bulk 3 is placed on the sheet 16 in a tightly aligned state, and then the movable plates 45 and 46 are expanded, and then the sweeper frame 12 is lifted to return to the original position.
Thereafter, by the same transfer operation, the bulks 3 are stacked on the pallet 8 continuously.
12A and 12B show a state in which a new bulk 3 is transferred onto the bulk 3 already stacked on the pallet 8.

In the palletizer constructed as described above, both the palletizing of the bulk 3 and the palletizing of the cases 5, ... As shown in FIG. Frame 1
The operation can be started immediately by mounting the case mounting base 13 on the surfaces 4 and 14. The steps will be described below in order.

First, after inputting and setting a desired load pattern on the operation panel 94, other palletizing information is input to the control box 96 (see FIG. 9) and the main switch is turned on to perform the following operations continuously. Automatically. That is, the cases 5, ... Are sequentially carried in from the entrance conveyor 85, while the case mounting table 13 is moved to the same height as the arranging conveyor 81, and the case mounting table 13 is moved upward at that position together with the sweeper frame 12. stand by.

Next, the cases 5, ..., Which are carried in from the entrance conveyor 85, are arranged in a square shape in advance for one stage so that the cases have a preset load pattern on the arrange conveyor 81.

Then, only the sweeper frame 12 moves up and moves horizontally to the upstream side, and descends so as to surround the case group C that has been aligned in advance (see FIG. 13A), and each movable plate 45. , 46 inwardly to reduce the shape of the cross girder to make the case group C aligned more tightly, and to actuate the brake to securely clamp the case group C.

After that, the sweeper frame 12 horizontally moves to the downstream side and the case group C is transferred onto the waiting case mounting table 13.

Next, the case platform 13 descends together with the sweeper frame 12, and the case platform 13 waits on the unloading line 7 for the pallet 8 (or the upper end of the case group CA already stacked). ) It stops at a position slightly higher than), and the sweeper frame 12 horizontally moves to the downstream side together with the case mounting table 13 while holding the case group C, and the pallet 8 (or the case group CA already stacked). The case table 13 on which the case group C is transferred is made to correspond [Fig.
(B)]. In addition, in FIG. 13 (B), the pallet 8 has already been used.
The figure shows a state in which a new case group C is transferred onto the case group CA stacked on top of each other.

Then, first, only the case table 13 horizontally moves to the upstream side. As a result, the case group C in the sweeper frame 12 is moved to the pallet 8 (or the stacked case group C).
Sit directly on top of A) while maintaining a tight alignment [see FIG. 13 (C)].

Thereafter, the movable plates 45 and 46 expand outward to release the nipping of the case group C, and after the sweeper frame 12 moves upward, it horizontally moves to the upstream side and returns to the original position. At this point, the next case group C has been aligned in advance on the arrange conveyor 81, the sweeper frame 12 descends with respect to the case group C, and thereafter, the same work is repeated.

Next, when palletizing the bulk 3 in place of the cases 5, ..., The two bolts 76, 77 fixing the case mount 13 are unfastened to remove the case mount. By removing 13, the palletizing operation of the bulk 3 can be performed automatically and continuously as described above by a command from the control box 97 dedicated to the bulk (see FIG. 9).

As described above, by simply attaching and detaching the case mount 13 to and from the transfer device 6, one palletizer 1 can be used for both cases 5, ... And bulk 3 pallet loading. Since the attachment / detachment is extremely easy with the two bolts 76, 77, the replacement time is very short, and the idle time of the line can be extremely reduced to significantly improve the operation rate of the palletizer 1.
