Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load processing apparatus for taking out a desired number of packages stacked on a pallet or the like and stacking them on another pallet or the like.

[0002]

2. Description of the Related Art Conventionally, a plurality of packages stacked on a pallet in a plurality of layers, each of which has a plurality of layers, may be replaced on another pallet in units of the number of layers. For example, in a canned beverage production plant, cardboard boxes containing canned beverages are stacked on pallets for each type of beverage, and a desired number of layers are taken out of these pallets, and various types of pallets are provided for each shipping destination. As such a load processing device for unloading each layer, the present applicant runs a carriage between above the step-down section and the stacking section, and reciprocates between the layers of the packages stacked in the step-down section. There has been proposed a device in which a table is entered to scoop up luggage (for example, Japanese Utility Model Publication No. 7-14266).

[0003]

However, in the above-mentioned conventional load processing device, when the load is scooped up by the carriage, and the load is changed, the load is changed one layer at a time. In the case of replacement, it is necessary to reciprocate the carriage by reciprocating the carriage many times, which is inefficient. In the transfer between pallets in the physical distribution process, a multi-layer transfer is often performed between the same pallets, and it is demanded that the transfer be performed efficiently.

[0004] It is an object of the present invention to provide a cargo handling apparatus capable of efficiently transferring a plurality of layers of cargo.
Another object of the present invention is to reduce the cycle time and to further improve the transfer efficiency while preventing load collapse. Still another object of the present invention is to suppress deflection of a leading carriage roller of a carriage and allow a plurality of layers of cargo to be scooped up without any trouble.

[0005]

According to the present invention, there is provided a cargo handling apparatus having a step-down unit having a lifting platform device for loading packages in a stacked state, and a loading platform arranged in parallel with the step-down unit. The stacking unit, the lifting device of the step-down unit and the loading platform of the stacking unit are provided so as to be able to reciprocate above the loading table, and the step-down unit is moved in accordance with traveling to the step-down unit side. And a carriage that can enter between layers of luggage stacked in the section and scoop up luggage. In the cargo handling apparatus having this configuration, interlayer position selecting means for selectively positioning various interlayer positions of the loads stacked on the step-down section is provided at the entrance height position of the carriage. And According to the load processing device having this configuration, the elevator device of the step-down unit selectively positions the various interlayer positions of the stacked loads at the entrance height of the carriage in accordance with the interlayer position selecting means. For example, the inter-layer position between the second and third layers of luggage from the top is positioned at the entrance height of the carriage. The carriage travels to the step-down section, enters between the layers of the load, and scoops the load above the layer. If there are two or more layers above the carriage, the packages stacked on the two or more layers are scooped up in the stacked state. The carriage that scooped up the luggage runs in the opposite direction and unloads the luggage at the stacking section. In the step-down section, the interlayer position of the stacked luggage is again selectively positioned at the approach height of the carriage,
When the carriage re-enters, the luggage at the step-down section is scooped up. Such an operation is repeated, and an arbitrary number of layers of the luggage in the step-down section are replaced on the stacking section. In this case, since the various interlayer positions of the load are selectively positioned at the entrance height position of the carriage, it is possible to scoop up the load of the plurality of layers by the carriage in the stacked state and to carry it to the stacking unit. it can. As described above, since a plurality of layers of luggage can be transferred at the same time, a multi-layer transfer can be efficiently performed.

In the present invention, in the traveling process in which the carriage moves toward the step-down portion and scoops up the luggage, the carriage travels at a higher speed than before the abutment until it comes into contact with the luggage. It is also possible to provide a carriage control means for causing the luggage to travel at a speed according to the situation of the luggage to be scooped. What is the status of your luggage?
At the same time, the number of layers, the stacking height, and the weight of the baggage to be scooped, the height of the baggage of each layer, and the like. Until the carriage comes into contact with the luggage, no problem occurs even when the vehicle is driven at high speed. After the abutment, the carriage enters between the layers of the luggage, and is accompanied by vibration or inclination. Therefore, when the traveling speed is high, the carriage may become unstable depending on the loading condition of the luggage and may collapse. Therefore, by increasing the traveling speed within a safe range in accordance with the load status of the load, the cycle time of reciprocation of the carriage can be reduced without load collapse, and the transfer efficiency can be improved.

In each of the above configurations of the present invention, the carriage is provided with a plurality of carriage rollers between a pair of carriage side frames, and the back of the first carriage roller on the step-down portion side. In addition, a supporting roller that supports the carriage roller by rolling at an intermediate portion in the longitudinal direction may be provided. The carriage roller at the head of the carriage receives a large resistance when entering between the layers of the load, and is likely to bend. This bending is hindered and suppressed by the support roller that rolls on the roller back surface at the intermediate portion of the carriage roller. The use of the supporting roller that rolls on the roller back surface reduces the resistance and does not hinder the rotation of the roller. In this manner, the deflection of the carriage roller can be suppressed, and a plurality of layers of luggage can be scooped up without any trouble without causing poor scooping due to the deflection of the carriage roller.

The entry side support member 15 and the pair of side support members 16 of the baggage four-way support means 11 and the stopper 17, the shutter 18 and the pair of side restriction members 19 of the drop-off alignment means 20 are all carriages. It is also possible to use a vertical width that can push the luggage W of each stage of the luggage W stacked in a plurality of stages on the height position, and it is possible to push only the lowest luggage W in the plurality of luggage W It is good also as thing of a suitable top and bottom width.

The operation of the above configuration will be described. The luggage W on the pallet P1 on the side of the step-down unit 1 in FIG. 1 is, for example, a can, a bottle, or a cardboard box containing a beverage in a resin container.
On a conveyor (not shown) following the conveyor 6, a plurality of pallets P1 on which packages W are placed by type are sequentially arranged and made to stand by. The layers of the stacked packages W are bonded to each other with a hot-melt type adhesive (not shown) so as not to collapse during transportation. The pallet P2 on the stacking unit 2 side is a pallet prepared for each shipping destination.

As shown in FIG. 17A, when the pallets P1 in a stacked state are conveyed by the carry-in conveyor 6 to a predetermined position of the step-down unit 1, the carry-in conveyor 6 is stopped, and the elevator platform 7 is moved. Then, the pallet P1 of the carry-in conveyor 6 is lifted. The inter-layer position of the load W set by the inter-layer position selecting means 26 (FIG. 19) corresponds to the carriage entrance height H as indicated by a chain line.
Is reached, the lift of the lift device 7 stops. FIG.
This is an example in which luggage W for a layer is simultaneously reloaded, and the inter-layer position of the second layer and the third layer is set to the carriage entry height H.

After this stop, as shown in FIG. 17 (B), the facing support member 14 of the four-way support means 11 and the facing clamp members 12a, 13a of the first and second clamping means 12, 13 are moved. The vehicle advances to a predetermined position corresponding to the load W, the approach-side support member 15 moves down to the closed position and advances, and the approach-side clamps 12b and 13b of the first and second clamps 12 and 13 advance. Further, the pair of side support members 16 advance, and the upper surface pressing means 40
Descends. Thus, the load W above the carriage entry height H is sandwiched from all sides by the facing support member 14, the approach support member 15, and the pair of side support members 16, 16 of the load four-way support means 11 ( 15), and is pressed by the upper surface pressing means 40 from the upper surface. In addition, the luggage W in the lower layer of the carriage entrance height H is sandwiched between the first and second facing clamp members 12a and 13a and the entrance clamp members 12b and 13b. The first and second clamping means 12, 13 may sandwich the baggage W at the same time as described above, or may be clamped by one of the clamping means 12, 13 depending on the type of the baggage W or the like. But it is good.

In the state of being supported and clamped in this way, the carriage 5 waiting on the side of the stacking section 2 rotates the leading drive carriage roller 10A upward (in the direction of the arrow a) while rotating the leading carriage roller 10A upward. Drive to one side. When the driving carriage roller 10A hits the side surface of the load W, the load W is scooped up by the frictional force of the rotation, and the carriage 5
Between the layers. Therefore, the load W above the layer is loaded on the carriage 5 as the carriage 5 travels (FIG. 17C). At this time, the luggage W scooped up by the carriage 5 is sandwiched from all sides by the luggage support means 11 and the upper surface is pressed by the upper surface pressing means 40. There is no collapse. As described above, since the baggage W is surrounded by four sides and pressed from above, the luggage W has a shape that is high with respect to the depth,
Even when a plurality of stages are picked up at the same time, collapse of the package is prevented. At the time of the scooping, the adhesive bonding between the layers of the load W is in a peeled state. If the peeling is not performed smoothly, the luggage W may try to move upward due to the recoil due to local sudden peeling or the like. The load W is prevented from being pressed from above.

Of the support means in each direction constituting the baggage four-way support means 11, the facing side support member 14 is provided with a retreat portion 63 at a lower portion, and is provided by the retreat portion 63 until the carriage 5 approaches. Also support the luggage W. When the carriage 5 approaches, the evacuation unit 63 moves up and retreats, and the facing support member 14
The carriage 5 enters below the space. Therefore, without hindering the operation of the carriage 5,
The load W can be supported to the bottom, and the positional displacement of the load W can be more reliably prevented.

When the load W is scooped by the carriage 5, the load W, which is one layer below the scooping layer, is first and second.
Of the clamp means 12 and 13 or both. Also,
It is also prevented that the position and posture of the luggage W in the layer one step below the scooping layer is disturbed and the entry of the carriage 5 is prevented, and smooth scooping is performed. The first clamping means 12 includes:
As shown in FIG. 14, since the center or lower part of the luggage W is pushed, the luggage W contains contents w such as a bottle with a narrow mouth as shown in FIG. Even if there are many items, it is possible to press a place where the contents w of the baggage W are full. Therefore, even if the luggage W has a lot of space in the upper part and low rigidity such as a cardboard box, the luggage W can be securely grasped without being deformed by the clamping force, and the collapse of the luggage can be prevented. You can scoop up. In the case where the second clamp means 13 for pressing the vicinity of the upper end of the load W is used, the load can be pinched at a position immediately below the carriage 5, so that the collapse of the load due to the pinch by the clamp means is further ensured. . Further, when the first clamp means 12 for pressing the middle or lower part and the second clamp means 13 for pressing the upper part are used together as in this embodiment, the load W of various heights is surely secured. It is possible to prevent the collapse of the load and to scoop up. When the clamp selection control means 28 (FIG. 19) for selectively operating the first and second clamp means 12 and 13 in accordance with the load W located between the clamp means 12 and 13 is provided, It is possible to securely clamp the luggage W of the size and the type without damaging the luggage W with unnecessary clamps.

Since the clamp members 12b and 13b on the entry side of the clamp means 12 and 13 are divided into a plurality of parts, the second clamp means 13 is partially divided as shown in FIG. Even if there is a gap d between the luggage W,
As shown in FIG. 3B, each divided clamp member 13b
The luggage W is clamped for each row at a and 13ba, and clamped without a gap. Therefore, reliable clamping can be performed,
The carriage 5 can smoothly scoop up the luggage W. Further, not only when there is a gap between the packages W, but also when the length of each row of the packages W is different,
By pressing, reliable clamping can be performed.

The carriage 5 shown in FIG. 14 travels toward the step-down section 1 to scoop up the load W, and is controlled by the carriage control means 27 (FIG. 19) until it comes into contact with the load W. Is driven at high speed, and after contact, the luggage W
Drive at a speed appropriate for the situation. The status of the load W includes the number of layers, the stacking height, and the weight of the load W to be simultaneously scooped, the height of the load W in each layer, and the like. Thus, the carriage 5
Is made to travel at high speed until it comes into contact with the load W, and after the contact, the traveling speed is increased within a safe range according to the loading condition of the load W, so that the carriage 5 can reciprocate without collapsing. Cycle time can be shortened, and the transfer efficiency can be improved. The carriage roller 10 at the head of the carriage 5
A receives a large resistance when entering between the layers of the baggage W and is likely to bend. However, since it is supported by the support roller 35 (FIGS. 6 and 7) at the intermediate portion, the bending is suppressed and the carriage roller 10A And a plurality of layers of luggage W can be scooped up without any trouble.

After the luggage W has been scooped up by the carriage 5 in this manner, as shown in FIG. 18A, the facing support member 14 of the four-way luggage support means 11, the retreating of the entry-side support member 15, and the upward movement. The opening operation, the opening of the pair of side support means 16, and the upward movement of the upper surface pressing means 40 are performed, and the carriage 5 moves backward to the stacking unit 2 side. In addition, the first and second clamping means 12 and 13 release the clamp by retreating the clamp members 12a, 13a, 12b and 13b on the facing side and the entrance side, and prepare for the next rise of the load W.

When the carriage 5 travels to the predetermined position of the stacking unit 2, after the traveling is stopped, the luggage W on the carriage 5 is sandwiched back and forth by the shutter 18 and the stopper 17 of the arranging means 20, (FIG. 18B). In this state, the carriage 5 moves the shutter 1
By moving under the step 8 and traveling down to the step 1 side, the load W on the carriage 5 is stopped by the shutter 18 and is dropped on the pallet P2. Carriage 5 is stacked part 2
In the step-down unit 1, the elevator unit 7 is
The next arbitrary number of steps is raised, and the load W above the carriage entrance height H is surrounded and supported by the load four-way support means 11 as described above, and the load W one step below the load W is first and second. The apparatus stands by while being clamped by the clamping means 12 and 13. Therefore, when the carriage 5 travels to the step-down unit 1 side to remove the luggage W, by continuing traveling as it is,
The luggage W for one or more layers next to the step-down unit 1 is scooped up on the carriage 5 (FIG. 18C).

As described above, the carriage 5 is reciprocated to take out the desired number of packages W on the pallet P1 of the step-down unit 1.
The sheets are stacked on the pallet P2 of the stacking section 2. At this time, according to the interlayer position selecting means 26 (FIG. 19) as described above, a plurality of layers of loads W can be simultaneously scooped by the carriage 5, so that a large number of loads W can be efficiently pallets P1, P
Can be replaced between the two. The leftover luggage W of the step-down unit 1 is lowered from the elevating platform device 7 onto the carry-in conveyor 6 together with the pallet P1, and is carried out from the subsequent conveyor (not shown). In the above repetition process, the step-down unit 1 of the carriage 5
The movement to is performed after the load detecting means 62 (FIG. 10) detects that the load W is above the carriage height H in the step-down unit 1. In this case, the load detecting means 62
Since it is provided in the baggage four-sided support means 11, the load can be detected without the detection route being hindered by the baggage four-sided support means 11.

It should be noted that, in the above embodiment, the stacking section 2
Uses the lifting platform device 9 as a loading platform and stacks it on the pallet P2. However, the loading platform may be a conveyor, a cart or the like.
