Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple depalletizer for correcting misalignment of cans and automatically discharging inverted cans.

[0002]

2. Description of the Related Art Conventionally, there is an automatic depalletizer which sequentially moves the cans in each stage and finally aligns them in a line in order to take out one can from the package of the cans.

The applicant of the present invention has previously proposed a simple depalletizer (Japanese Patent Application No. 3-295202).
issue).

[0004]

The above-mentioned conventional automatic depalletizer requires a vast area and an automated and complicated structure, and the installation cost is inevitably high. There was a problem limited to (for example, 10,000 cans or more per day). Since the conventionally known method is a method of horizontally pushing out a group of cans on a chipboard with a can sweeper (pushing plate), and then sequentially arranging them in a line and sending them out.
The height relationship between the chipboard and the next conveyor had to be adjusted exactly. However, the chipboard is greatly curved, depending on the weight of the stacking cans,
By shrink-wrapping the outside of the stacked cans, the four corners of the chipboard may be bent, so it was difficult to prevent the cans from tipping over when the cans were pushed out horizontally by the can sweeper.

[0005] Further, the small and medium-sized customers depended on human power without installing an automatic depalletizer, but according to human power, it is difficult to collect workers due to heavy labor and simple work, and the efficiency is improved. There was a difficult problem.

The simple depalletizer proposed by the patent applicant of the present invention has a problem that the overturned can hinders smooth can ejection of normal cans when the can rows are disturbed due to collapse of the can packing. If there is a point and the chipboard is bent,
There was a risk that the can could get caught and hinder smooth movement.

[0007]

SUMMARY OF THE INVENTION The present invention, however, is an improvement of the simple depalletizer described above, unpacking the cans, and arranging the cans in a line when the cans are taken out from the same stage of each cans. The above-mentioned conventional problems were solved by adding a means for preventing a can or eliminating a can.

As described above, in the present invention, it is not necessary to strictly regulate the height between the chip board and the next transfer section (conveyor), and the chip board is positioned below the edge of the next drop gap. By pressing as much as possible and giving the magnet hand forward, suction, ascending, retracting, descending, releasing, and retracting operations, the tipping of the can due to the bending or bending of the chipboard is prevented, and the tipping can is automatically separated. do it,
The above-mentioned conventional problems were certainly avoided.

That is, according to the present invention, a package in which a predetermined number of cans are stacked is lifted, then the top can of the package is slid horizontally along the chip board, and the cans are addressed to one row in the front row. In the device to be moved to the discharge conveyor by the can traverser, a spring is provided behind the push plate of the can for the cushion at the time of pressing the can, between the chip board edge and the discharge conveyor, Another simple invention is a simple depalletizer characterized by being provided with an inversion can dropping means, and another invention is to raise a packaging body in which a predetermined number of cans are stacked, and then place the topmost can of the packaging body along the chip board. In a device in which the cans are slid in the horizontal direction and moved onto the one-row discharge conveyor in the front row, a spring is provided behind the can extruding plate for cushioning when pressing the cans. Is a simplified Deparetaiza, characterized in that the. Still another aspect of the invention is that the can traverser is configured to repeat forward movement, adsorption, upward movement, backward movement, downward movement, release, and backward movement. Next, the falling means of falling can of another invention,
It is characterized in that it is a drop gap of a can provided between the edge of the chipboard and the discharge conveyor, and other means for dropping fallen cans are provided between the edge of the chipboard and the discharge conveyor. It is characterized by combining the drop gap of the can, and the raising and lowering and advancing / retreating operations of the can traverser.

In the above description, the edge of the drop gap of the can is made slightly higher than the chip board. Therefore, when the can group is extruded in the direction of arrow 14 in FIG. Abutting the edge, the position is almost determined. . However, if an inverted can or a slant can remains for some reason, it will move to the magnet hand of the can traverser in an insufficiently attracted state, and it will drop automatically due to its own weight drop into the drop gap of the can. Will be.

In the above description, the edge portion of the chip board may be bent by shrink wrapping during can packaging, which may hinder horizontal movement of the can.

In the above description, the spring is provided behind the extruding plate, but other elasticity (for example, elastic pressure of rubber or air pressure) can be used instead of the spring.

[0013]

According to the present invention, since the spring is provided behind the can extruding plate, the can row can be automatically corrected in cooperation with the traverser. Further, since the drop gap of the can is provided between the edge of the chip board and the discharge conveyor, the can that could not be properly attracted to the magnet hand of the can traverser will fall into the drop gap by its own weight. Cans can be automatically removed before the discharge conveyor.

[0014]

Embodiments of the present invention will be described with reference to the accompanying drawings.

That is, a large number of cans are piled up and down, and the integrated can group packing body 1 (FIG. 9) is placed on the hoist hydraulic lifter 2 (FIG. 1), and the packing material 28 is unwound. ,
The top frame 3 is removed manually or automatically (FIG. 9). Then, by operating the hydraulic lifter 2, the front edge of the chip board 12 on which the uppermost can group is placed is interposed between the front edge of the chip board 12 and the can discharge conveyor 4 installed on one side of the can group. The edge projections 24 of 24 are raised until they are hooked. This height is controlled by, for example, the sensor 34 (see FIGS.
5).

A traverser 43 (a can ejecting mechanism mainly composed of a magnet hand 6) is installed on the can ejecting conveyor 4 parallel to the can ejecting conveyor 4 so as to face the cans 5 and 5. On the left and right of the can group (Fig. 1), the guide plate 2
5, 25a are provided vertically. Therefore, the package 1 rises between the guide plates 25 and 25a. Further, a can pushing plate 8 is opposed to the rear of the can group (FIG. 2), a supporting rod 8a is arranged behind the pushing plate 8 via a spring 38, and both ends of the supporting rod 8a are fixed. , Chains 9 and 9 for moving this at low speed (advancing to the side of the can removing conveyor 4)
a and a can sweeper 1 including sprocket wheels 10, 10, 10a, 10a for mounting the chain 9, 9a
1 is installed. Further, the top frame 3 or the chip board 12 is located above the can group, but this is removed manually at an appropriate time. Although the chip board 12 can be automatically removed by using the suction transfer device 29, if the suction transfer device is attached, the depalletizer cannot be complicated and the installation space cannot be increased. . The suction moving device 29 includes, for example, a suction head 48, a fluid pressure cylinder 35, a rod 36, and a head rod 37.
The object can be achieved if it is configured to be able to move up and down and move laterally as shown by arrows 26 and 27 (FIG. 1).

In the above embodiment, the hydraulic lifter 2 in FIG. 1 is lifted in the direction of the arrow 13 almost intermittently to the height of the can by a predetermined control device (FIG. 1). Next, the top frame 3 is removed, and the sprocket wheels 10 and 1 are
When 0, 10a, 10a are rotated and the chains 9, 9a are moved in the direction of arrow 14 (Fig. 2), the pushing plate 8 also moves in the same direction, and the cans are horizontally placed on the chip board 12 as they are ( Press in the direction of arrow 14). In this way, the front row of the can group comes into contact with the edge projection 23 of the falling can drop gap 24 and stops (FIG. 5). On the other hand, when the sensors 15 and 15a detect that the front row of the can 5 has reached a predetermined position, the pressurized fluid is sent to the fluid pressure cylinder 16 and the rod 17 thereof is ejected in the direction of arrow 18. (FIG. 2), the magnet hand 6 (including the magnet 6a) is brought close to the front row of the can group as shown by the arrow 19 and brought into contact with the cans 5, 5. Then, an electric current is applied to magnetize the magnet 6a, and the cans 5 and 5 are magnetically attached to the magnet hand 6. After the cans in the front row are aligned in this way, the push-out plate 8 is moved backward, and the traverser 43 is moved upward, backward, downward, released, and backward so that the sucked cans 5 and 5 are removed. Move to the top and release the can 5. Generally, the packed cans have an irregular row of cans due to vibration during transportation and other factors. Therefore, when the top board 3 is removed, a small number of cans are displaced from the original can row like the cans 5a shown by hatching in FIG. In this case, the magnet hand 6 and the push-out plate 8 are pressed and sandwiched (see FIG.
(C)) The can rows are corrected and aligned. The alignment of the can row can be corrected relatively easily because the spring 38 is provided behind the pushing plate 8. Then, the cans can be moved onto the can take-out conveyor 4 by raising, retreating, and lowering the magnet hand 6 and cutting off the magnetism. The can conveyer 4 is constantly moving, but the magnet plate 44 is provided at the bottom.
Since the lower part of the can carried on the can removing conveyor 4 by the magnet hand 6 turns off the magnetism of the magnet hand 6 immediately before contacting the can discharging conveyor 4 (see FIG. 5).
(G)), since each can is attracted to the magnet plate 44, the arrow 2
It advances in the direction of 1 (FIG. 2), then advances in a line between the guide plates 22, 22, and is sent to the next step (FIG. 2).
The can sweeper 11 in the above includes the sensors 15, 15
The motor (not shown) is started by the output (detection of no can), and the sprocket wheels 10 and 10 interlocked with the motor are moved in the direction of arrow 14 to move about one can row. The sensors 15 and 15 again stop the motor. When the last row of cans is pushed out by repeating the forward movement and the stop as described above, the sprocket wheels 10, 10, 10a, 10a are reversed and the pushing plate 8 is moved backward to the starting position. Such movement is stored in the control circuit of the motor in advance,
The repetitive operation can be fully automated. Further, the forward movement of the magnet hand 6 causes the can 5 on the can conveyer 4 to move.
It is controlled so that the sensor 15a, 15a confirms that there is no more than one can, and outputs it. The can discharge conveyor 4 has a wide width so that even if the can passages formed by the guide plates 22 and 22 are bent like the guide plates 22a and 22a, they can be completed on the same conveyor. The refraction of the can passage is for facilitating detection by the sensors 15a and 15a. The upper edge 23 of the falling can drop gap 24 is set slightly higher than the front edge of the upper surface of the chip board 12, and the magnet hand 6 is indicated by arrows 39, 40, 41 in FIG.
Ascending and descending and moving forward and backward as shown in
((B) in FIG. 6) is indicated from the drop gap 24 by its own weight.
Discharge like 7.

The mutual relationship between the magnet hand 6 and the can pushing plate 8 and the moving state of the can in the above embodiment are shown in FIG.
(A), (b), (c), (d), (e), (f),
(G) and (h) will be described.

First, when the can group is lifted by the hydraulic lifter 2 (FIG. 5A), the uppermost chip board 12 is detected by the sensor 34, and the hydraulic lifter 2 is stopped. In this case, the edge of the chip board 12 is hooked on the edge projection 23 of the fall can drop gap 24 (FIG. 5).
(B)). Next, the left and right guide plates 7, 7a are attached to the cylinder 3
The rods 32 and 32a of 0 and 30a indicate the arrows 33 and 33.
As shown in a, the cans are respectively moved inward, and the cans are sandwiched from the left and right and held as they are (FIGS. 7A and 7B). Then, the push-out plate 8 is pushed out as shown by the arrow 45 to bring the front row of cans into contact with the edge projections 23.

Next, the magnet hand 6 is moved forward as shown by the arrow 41 to magnetize the magnet of the magnet hand 6 which is pressed against the cans in the front row so as to attract the cans. At this time, the pushing plate 8 moves backward against the spring 38 (see FIG. 5).
(C)). Next, the push-out plate 8 is retracted in preparation for taking out the cans in the front row (FIG. 5D). The magnet hand 6 attracting the can 5 is raised as shown by an arrow 39 (see FIG.
(E)) and withdrawal as shown by the arrow 42 (see FIG. 5).
(F)) and lower it as shown by the arrow 40 (FIG. 5 (g)),
Then, it is retracted as shown by arrow 46. On the other hand, when the magnet hand 6 is retracted, the push-out plate 8 is moved forward as shown by the arrow 45 (FIG. 5 (f)), the remaining can row is brought into contact with the edge projection 23 (FIG. 5 (g)), It waits for the hand 6 to move forward (FIG. 5 (h)).

In this way, when the dispensing of all the cans is completed, the pushing plate 8 and the guide plates 7 and 7a retreat to their original positions, and the cans on the hydraulic lifter 2 are lifted again by a predetermined distance.

As described above, by arranging the can rows each time the can rows are moved, it is possible to eliminate the cans.
Further, by moving the magnet hand 6 up and down and moving back and forth, it is not necessary to keep the height accuracy of the chip board 12 and the upper end of the edge projection 23 high. Further, even if the edge of the chip board 12 is bent, the movement of the can 5 is not hindered.

In the above, when the can row is not sufficiently corrected (for example, FIG. 4B), when the magnet hand 6 comes into contact with the can in the front row, the aligned cans 5 are adsorbed correctly, but misaligned. As shown in FIG. 6B, since the can 5a of No. 5 enters the falling can drop gap 24 with insufficient adsorption, the can 5a is automatically excluded by dropping from the gap by the own weight of the can 5 as shown by an arrow 47. (FIG.6 (c)).

[0024]

According to the present invention, since a group of cans on the same plane are taken out in a row and sequentially moved laterally, a series of operations from a large number of cans to an alignment of cans in a row can be easily performed. Not only can it be automated, but it is also effective in preventing upset cans and other can rows from being disturbed. It also has the effect of automatically eliminating cans and other cans that are not in the correct posture, thus facilitating smooth feeding after cans.

Further, even when the chip board is bent or curved, the can can be taken out in an orderly manner.
