JP7765875B2 - Loading device for carts - Google Patents

Description

The present invention relates to a device for loading cargo onto a cart, which loads boxed cargo onto a cart in a manner that is highly efficient.

As people's tastes become more diverse, a wide variety of goods are produced. These diverse goods are produced by a variety of manufacturers, whether in Japan or overseas, in various regions. As a result, many goods need to be delivered from various regions to other regions.

These items are delivered by manufacturers to retailers, wholesalers, etc. Alternatively, they may be collected by a delivery company, which then delivers various items together.

In addition, internet shopping is booming. Customers have moved away from the traditional style of visiting brick-and-mortar stores (supermarkets and department stores) to purchase and take home goods, and are now ordering goods online and paying electronically. Even with this type of internet shopping, the ordered and paid-for goods still need to be delivered to the purchaser.

In such cases, various goods are delivered to the purchaser by manufacturers, retailers, etc., or are collected and delivered by a delivery company. Goods are often delivered in boxes such as cardboard boxes. This is to prevent damage to the goods during delivery and to manage the delivery destination and delivery volume.

Of course, there are various situations where it is necessary to load multiple boxes filled with the same type of item onto a cart. There are many cases where multiple cardboard boxes filled with the same product are loaded onto a cart.

Entities with various roles, such as manufacturers, retailers, and delivery companies, deliver goods to where they are needed.

As mentioned above, items are often not delivered as is, but rather stored in boxes such as cardboard boxes and delivered. In other words, items are delivered as parcels in boxes. Delivery management is carried out by attaching barcodes or two-dimensional barcodes to the boxes.

The boxed goods are then loaded onto trucks, freight trains, ships, etc. for delivery. To improve work efficiency, the boxed goods are then loaded onto trucks on carts or similar. Loading a large number of items together onto trucks or similar improves delivery efficiency.

Of course, loading multiple packages onto a basket cart reduces the workload and physical strain on workers. It also has the benefit of increasing the efficiency of unloading the packages after delivery. For example, by loading multiple packages for the same delivery destination onto a single basket cart, delivery and work efficiency can be improved. This is because all that needs to be done is to hand over the basket cart, which has been transported by truck or other means, to the delivery destination.

As such, there is a need for efficient loading systems for delivering packages containing a wide variety of items. Technologies related to this have been proposed (see, for example, Patent Documents 1 and 2).

JP 2015-37992 A

Patent Document 1 discloses an automatic stowage system that includes a product case transport step that picks out corresponding product cases 12 based on shipping instruction information and transports them on a belt conveyor (transport means) 14; a product case sorting step that recognizes characteristic information of the product cases 12 and sorts and transports them to storage transport means 20 corresponding to the characteristic information; a cart truck movement step that moves cart trucks 22 used to load the product cases 12 and transport them to the shipping destination to a stowage area 26 for the product cases 12; a product case stowage step that creates stowage data from the shipping instruction information, characteristic information of the product cases 12, and the loading state of the product cases 12, and stows the product cases 12 on the cart trucks 22 in a predetermined position and order based on the shipping instruction information; and a cart truck unloading step that unloads each cart truck 22 from the stowage area 26.

However, in order to load products onto a transport vehicle using an automatic mechanism, it is necessary to create a distance between the products being loaded onto the transport vehicle in order to ensure the operating area required for this mechanism to operate. Alternatively, loading products using an automatic mechanism inevitably results in a distance between the products.

In addition, the width of the transport cart is not proportional to the width of the product, so when multiple products are loaded horizontally on the transport cart, gaps can inevitably occur.

As such, if there is a gap between packages loaded on a transport vehicle, there is a risk that the packages may tip over during transport by truck, etc. Naturally, if packages tip over, this can cause problems such as damage to the products and goods stored inside.

To prevent the dolly from tipping over, it is necessary to wrap the loaded cargo in film to secure the cargo. This poses problems such as cost and effort, as well as the hassle of unloading the cargo after delivery.

As described above, conventional technologies such as Patent Document 1 disclose techniques for automatically loading cargo onto a cart, but they have the following problems: (1) gaps occur between the cargo items, (2) cargo items may tip over when transported with gaps, (3) the efficiency of loading cargo onto the cart decreases, and (4) measures to prevent tipping increase the effort and cost required.

In addition, at actual work sites, a row of cargo would be too wide to fit into a loading truck, so the work was done by hand, resulting in a "crammed" loading operation, where the width of the truck matched the overall width of the cargo. Naturally, all of the placing, loading, and proper stowing had to be done by hand, which created the problem of not being able to place or load cargo by machine in the first place.

Furthermore, at actual work sites, a skilled worker could load a row of cargo that would be too wide to fit into a truck if loaded by machine, while keeping an eye on the load, and thus achieve a tightly packed load so that the width of the truck matched the overall width of the cargo. Naturally, all of the placing, loading, and proper loading was done manually, which presented the problem of not being able to place or load cargo by machine in the first place.

In addition, loading large quantities of cargo onto a cart by hand is difficult due to issues such as the labor and time required. As mentioned above, large quantities of cargo need to be loaded onto the cart one after another, which is difficult to do by hand. Furthermore, loading cargo in a way that leaves gaps will lead to continuous problems such as cargo shifting during transport. Alternatively, loading would require a combination of machinery and human labor, which is also unrealistic.

In other words, in addition to the problems mentioned above, conventional technology also had the problem of being unable to efficiently load large amounts of cargo onto a cart.

In consideration of the above-mentioned problems, the present invention aims to provide a device for loading luggage onto a car cart that efficiently loads luggage onto the car cart while minimizing gaps between luggage pieces.

In view of the above problems, the present invention provides a device for loading luggage onto a car truck, which loads luggage onto a first stage, a second stage, ..., an Nth stage upward from a bottom plate of the car truck, and which comprises:
a take-out mechanism that takes out luggage corresponding to the first tier, second tier, ..., Nth tier (hereinafter referred to as "loading tier luggage") from the luggage storage area that stores the luggage;
a transfer mechanism for transferring the load-carrying-stage baggage removed by the removal mechanism;
a loading mechanism for loading the transported loading stage cargo onto the car truck;
The loading mechanism includes:
a mounting unit including a first mounting table, a second mounting table connected to one side of the first mounting table, and a third mounting table connected to the other side of the first mounting table;
a movement control unit that controls vertical movement of the first table, horizontal movement of the second table, and horizontal movement of the third table;
a loading control unit that controls an operation of inserting the placement unit into or extracting the placement unit from the car cart,
The first platform is capable of placing luggage thereon and is movable up and down;
The second platform is capable of placing luggage thereon and is movable left and right,
The third platform is capable of placing luggage thereon and is movable left and right,
When the overall width of the loading stage luggage placed on the loading section is greater than the width of the car dolly (hereinafter referred to as "overwidth state"),
the movement control unit moves the first platform upward, and moves the second platform and the third platform toward the first platform, causing the plurality of packages to form a pile;
the loading control unit inserts the storage unit into the car truck in a state in which the plurality of packages on the storage unit are arranged in a pile;
When the overall width of the loading stage luggage placed on the loading section is equal to or less than the width of the car dolly (hereinafter referred to as "width or less state"),
the movement control unit causes the plurality of loads placed on the first load table, the second load table, and the third load table to be parallel to each other;
the loading control unit inserts the loading unit into the car truck while the plurality of luggage items on the loading unit are parallel to one another;
The car bogie includes a bottom plate and a side frame;
The side frame has a shape that expands upward from the bottom plate,
The width of the car bogies increases toward the first stage to the Nth stage.

The cargo loading device for a car dolly of the present invention can efficiently load the number of cargoes that can be loaded onto a car dolly. By improving loading efficiency, cargo delivery capacity can be improved and delivery costs can be reduced.

In addition, since the gaps can be reduced when loading cargo onto the cart, it is possible to prevent cargo from tipping over during transport. This prevents damage to the cargo and the need for replacement. It also eliminates the need for extra work, such as wrapping the entire cargo in film to prevent it from tipping over due to gaps.

In addition, by being able to load an optimized number of items according to the shape and size of the cart, overall costs and environmental impact can be reduced.

A luggage loading device onto a car bogie according to a first aspect of the present invention is a luggage loading device onto a car bogie that loads luggage onto a first stage, a second stage, ..., an Nth stage upward from a bottom plate of the car bogie,
a take-out mechanism that takes out luggage corresponding to the first tier, second tier, ..., Nth tier (hereinafter referred to as "loading tier luggage") from the luggage storage area that stores the luggage;
a transfer mechanism for transferring the load-carrying-stage baggage removed by the removal mechanism;
a loading mechanism for loading the transported loading stage cargo onto the car truck;
The loading mechanism includes:
a mounting unit including a first mounting table, a second mounting table connected to one side of the first mounting table, and a third mounting table connected to the other side of the first mounting table;
a movement control unit that controls vertical movement of the first table, horizontal movement of the second table, and horizontal movement of the third table;
a loading control unit that controls an operation of inserting the placement unit into or extracting the placement unit from the car cart,
The first platform is capable of placing luggage thereon and is movable up and down;
The second platform is capable of placing luggage thereon and is movable left and right,
The third platform is capable of placing luggage thereon and is movable left and right,
When the overall width of the loading stage luggage placed on the loading section is greater than the width of the car dolly (hereinafter referred to as "overwidth state"),
the movement control unit moves the first platform upward, and moves the second platform and the third platform toward the first platform, causing the plurality of packages to form a pile;
the loading control unit inserts the storage unit into the car truck in a state in which the plurality of packages on the storage unit are arranged in a pile;
When the overall width of the loading stage luggage placed on the loading section is equal to or less than the width of the car dolly (hereinafter referred to as "width or less state"),
the movement control unit causes the plurality of loads placed on the first load table, the second load table, and the third load table to be parallel to each other;
The loading control unit inserts the placement unit into the car truck in a state in which the plurality of packages on the placement unit are parallel to one another.

This configuration allows cargo to be loaded across the entire width of the cart without any gaps. This prevents gaps from forming and causing cargo to shift during transport. It also reduces the workload of manually packing cargo tightly.

In a second aspect of the present invention, in addition to the features of the first aspect, in the load loading device onto a car truck, in the width exceeding state, the movement control unit:
Lifting the first platform on which the luggage is placed,
bringing the second and third platforms, on which the luggage is placed, closer to the first platform;
The overall width of the bottom side of the load-stage baggage placed on the placement section is equal to or less than the width of the car truck.

This configuration makes it possible to load an oversized item onto a car dolly. In particular, the width of the bottom part of the loading stage cargo becomes smaller than it is in its original state, allowing it to be inserted even in the narrowness of the bottom of the car dolly. Once inserted, it can be loaded by pressing down from above and pushing it in.

A third aspect of the present invention provides a device for loading luggage onto a car truck, in addition to the first or second aspect, wherein the car truck includes a bottom plate and a side frame,
The side frame has a shape that expands upward from the bottom plate,
The width of the car bogies increases toward the first stage to the Nth stage.

This configuration allows cargo to be loaded even if it exceeds the width. In particular, automatic loading is possible using a mechanical cargo loading device rather than manual labor.

In a fourth aspect of the present invention, in addition to any one of the first to third aspects, the loading control unit
The loading sections on which the loading stage cargoes corresponding to the first stage to the Nth stage are placed are inserted into the car trucks;
After the loading stage cargo is loaded onto the car truck, the loading section is pulled out.

This configuration allows luggage to be loaded in stages.

In a fifth aspect of the present invention, in addition to the fourth aspect, the loading control unit is
In accordance with inserting the placing section into the upper stage of the stage that is in the over-width state among the first stage to the Nth stage,
The placing section is controlled so as to press down the plurality of piled up packages loaded on the over-width stage.

This configuration allows cargo that is packed in a curved position to be leveled (flat).

In the sixth aspect of the present invention, in addition to any one of the first to fifth aspects, the loading control unit sets the loading section to a height at which cargo is loaded on the first to Nth levels.

This configuration allows cargo to be loaded in layers.

In the seventh aspect of the present invention, in addition to any one of the first to sixth aspects, the loading device for a car dolly further includes a mechanism for removing luggage from the luggage storage area, transferring the number of luggage pieces corresponding to the loading level to the transfer means as the loading level luggage pieces.

This configuration allows luggage loaded by the loading mechanism to be transferred in sequence. It can also continue to load luggage from the luggage storage area onto a cart.

In an eighth aspect of the present invention, in addition to any one of the first to seventh aspects, the loading device for loading luggage onto a car truck further comprises:
a transfer means for transferring the loading stage cargo to the loading mechanism;
a placing means for placing the device on the placing portion;
Equipped with.

With this configuration, the number of load-level cargo items corresponding to the load level is transferred and placed on the loading mechanism's placement section. This allows the load-level cargo items transferred by the transfer mechanism to be connected and loaded onto the car trolley by the loading mechanism.

In the ninth aspect of the present invention, in addition to the eighth aspect, the device for loading luggage onto a car dolly includes a conveyor mechanism, which transfers the loading-stage luggage to a position corresponding to the placement section.

This configuration allows for efficient transport of cargo.

In the tenth aspect of the present invention, in addition to the features of the ninth aspect, the loading device for a car dolly places the load on the loading section by moving the load on the loading section in a direction intersecting the conveyor mechanism.

This configuration allows for loading using the loading mechanism.

In the device for loading luggage onto a car truck according to the eleventh aspect of the present invention, in addition to the tenth aspect, the loading means adjusts the position of the luggage on the loading stage.

This configuration allows items to be loaded in the correct position and alignment when inserted from the loading section onto the cart. Furthermore, whether they are loaded in a curved or parallel position, they are optimally adjusted to fit the width of the cart.

The following describes an embodiment of the present invention with reference to the drawings.

(Analysis by the inventor)
The inventor analyzed the gaps that occur when loading luggage onto a cart in the prior art as follows. Figure 1 is a schematic diagram showing the state of luggage loaded onto a cart in the prior art, based on the inventor's analysis. The width of the cart and the overall width of multiple luggage items often do not match (the width of the luggage items is not proportional to the width of the cart). As a result, when luggage items are loaded onto the cart, they do not fit neatly, and the last item cannot be loaded. As shown in Figure 1, an excess area is created on the right edge.

If you try to fit another item into this remaining space, you have to force it in using human or mechanical means. This increases the amount of work required.

On the other hand, if multiple items of luggage are loaded with sufficient width, gaps will form between the items of luggage, as shown in Figure 2. Figure 2 is a schematic diagram showing how luggage is loaded onto a cart using conventional technology. In both cases, as shown in Figure 1 and Figure 2, the presence of gaps raises concerns that the luggage may tip over when the cart carrying the luggage is transported by truck or other vehicle.

Of course, as mentioned above, there is a problem with adding another piece of luggage and then manually or mechanically squeezing it in to eliminate the gap, which increases the effort and cost. Based on this analysis, the inventors have come up with a luggage loading device that efficiently loads multiple pieces of luggage to fit the width of the cart.

In particular, while it is not impossible to cram the items in tightly by hand, this increases the workload on the workers. Naturally, this requires additional human resources, making automation of loading difficult. Furthermore, manual work also increases the length of time required for the work.

(Embodiment 1)

(Overall overview)
Fig. 4 is a block diagram of the luggage loading device according to the first embodiment of the present invention. It shows the entire luggage loading device 1 as seen from above. In addition, Fig. 4 also shows an operator 500 who moves and operates the car cart loaded with luggage in the luggage loading device 1.

The luggage loading device 1 loads luggage 200 from the bottom plate of the car dolly 100 upwards on the first, second, ... Nth tiers. As shown in Figure 5, the first tier of luggage 200 is loaded from the bottom plate of the car dolly 100, the next luggage 200 is loaded on the second tier above the first tier, and so on up to the Nth tier. At this time, as shown in Figure 5, the luggage 200 loaded on the first to Nth tiers are lined up horizontally in groups of multiple luggage 200.

Figure 5 is a front view showing the state in which luggage is loaded onto a car truck in embodiment 1 of the present invention. The luggage is loaded in the order of the first tier to the Nth tier. The luggage 200 corresponding to each of the first tier, second tier, ..., Nth tier will be referred to as "loading tier luggage" as necessary.

The luggage loading device 1 comprises a removal mechanism 30, a transfer mechanism 40, and a loading mechanism 20.

The removal mechanism 30 removes luggage 200 corresponding to the first, second, ... Nth tier from the luggage storage area 220, which stores multiple luggage 200. The luggage storage area 220 stores a large number of box-shaped luggage 200, such as cardboard boxes. New luggage 200 may also be brought into the luggage storage area 220 one after another.

The removal mechanism 30 removes the loading-stage luggage from the luggage storage area 220. It then hands it over to the transfer mechanism 40, which ultimately loads the loading-stage luggage onto the car trolley 100.

In other words, the luggage loading device 1 has the function of moving and loading luggage 200 from this luggage storage area 220 to the car trolley 100.

The transfer mechanism 40 transfers the loading stage luggage removed by the removal mechanism 30 to the loading mechanism 20. Since the luggage is transferred as loading stage luggage, the unit of transfer is loading stage luggage. By transferring the luggage in units of loading stage luggage, the luggage can be loaded onto the car trolley 100 in the loading mechanism 20 in the form of loading stage luggage.

Figure 6 is a perspective view showing the operation of the transfer mechanism in embodiment 1 of the present invention. The transfer mechanism 40 transfers the loading stage luggage 210 as shown in Figure 6. The number of luggage 200 contained in the loading stage luggage 210 is determined by the comparison of the width of the car cart 100 and the luggage 200. The removal mechanism 30 removes the luggage 200 corresponding to this determined number in a batch and hands them over to the transfer mechanism 40 in the form of loading stage luggage 210.

The transfer mechanism 40 transfers the loading stage luggage 210 to the loading mechanism 20. This transfer enables the loading mechanism 20 to load the luggage 200 onto the car trolley 100 in the form of loading stage luggage 210.

The loading mechanism 20 loads the load-tier luggage 210 from the bottom plate of the car dolly 100 upward to positions corresponding to the first tier, second tier, ... Nth tier. As shown in Figure 5, the loading mechanism 20 loads the luggage 200 sequentially onto the car dolly 100.

The car dolly 100 loaded with the cargo 200 by the loading mechanism 20 is moved to the next stage by the worker 500. The worker 500 also places a new, empty car dolly 100.

In this way, the luggage loading device 1 can cover the entire process from the luggage storage area 220 to the removal of the loaded cart 100.

(Loading flow using the loading mechanism 20)

The flow of loading luggage onto the car dolly by the loading mechanism 20 will be explained using Figures 7 to 9. First, the loading flow (loaded state) will be explained. As explained using Figures 1 and 2, the width of the loading stage luggage 210 in the luggage loading device 1 can exceed the width of the car dolly 100 ("overwidth state"). Even under these circumstances, the luggage can be loaded so that it fits neatly into the car dolly 100.

(Loading the first load)
Fig. 7 is a schematic diagram showing the state in which the first level of luggage is being loaded onto a car dolly in an embodiment of the present invention. Fig. 7 shows the state in which the car dolly 100 is viewed from the front (the side that opens for loading luggage 200). Figs. 8 to 9 are similar. In Fig. 7, a loading level luggage 210 including a plurality of luggage 200 is loaded onto the first level, which is the lowest level of the car dolly 100.

At this time, multiple pieces of luggage 200 are loaded in a line (loading-tier luggage 210 state) across the width of the car dolly 100 (horizontal direction when viewed from the front in Figure 7). The overall width of the first-tier loading-tier luggage 210 may be larger than the width of the area of the car dolly 100 corresponding to the first tier (hereinafter referred to as "overwidth state"). Figure 7 shows this state.

When the width exceeds the limit, the loading mechanism 20 inserts multiple pieces of luggage 200 into the car truck 100 in a convex shape, as shown in Figure 3. The middle piece of luggage 200 is positioned higher than the pieces of luggage 200 on either side. This positional relationship makes the overall width of the bottom side smaller than it should be, allowing it to be inserted into the car truck 100.

Here, the car bogie 100 comprises a bottom plate 102 and side frames 101. The side frames 101 have a shape that widens upward from the bottom plate 102. This is shown in the front view of Figure 7. Because the side frames 101 on both sides widen upward, the width increases from the first level to the second level, third level, and so on.

First, the loading mechanism 20 loads the loading-stage cargo 210 onto the first stage. If the cargo exceeds the width, the central cargo 200 is raised as shown in Figure 7, and the first stage cargo 200 is loaded in a convex shape so that it fits within the width of the car dolly 100.

(1st to 2nd paragraphs)
Continuing from Fig. 7, Fig. 8 is a schematic diagram showing the loading of luggage from the first level to the second level. As shown on the left in Fig. 8, the luggage 200 is being loaded onto the car truck 100 by the loading mechanism 20, with the central luggage 200 raised and the luggage 200 on both sides in a lower position.

Next, the state shown on the right side of Figure 8 is reached. The loading mechanism 20 loads the second-tier load-stage cargo 210 on top of the first-tier load-stage cargo 210. As will be described later, the loading mechanism 20 is equipped with a loading section on which each tier of load-stage cargo 210 is placed. From a state in which the first-tier load-stage cargo 210 is loaded on the car dolly 100 as shown on the left side of Figure 8, the load-stage cargo 210 placed on the loading section is loaded into the second-tier position as shown on the right side of Figure 8.

As shown on the right side of Figure 8, when the second-tier loading cargo 210 is loaded, the loading section presses down on the first-tier loading cargo 210 from above. This pressure and the weight of the second-tier loading cargo 210 causes the curved first-tier loading cargo 210 to flatten out, as shown on the right side of Figure 8.

Furthermore, when the overall width of the second-stage loading cargo 210 is equal to or less than the width of the car dolly 100 (hereinafter referred to as the "width-or-less state"), the second-stage loading cargo 210 is loaded into the second stage position of the car dolly 100 while remaining parallel.

As a result, the curved first-tier load cargo 210 is pressed down and flattened, and the second-tier load cargo 210 is stacked flat. As shown on the right side of Figure 8, the load cargo 210 is flattened on both the first and second tiers. In this way, the load cargo 210 is stacked in a parallel, flat state from the bottom plate 102 to the upper tier.

Of course, if the second tier also exceeds the width limit, the second tier's loading tier cargo 210 will also be loaded in a curved state, just like the first tier. When the third tier's loading tier cargo 210 is loaded above the second tier, it will be pressed down from above by the loading section, causing the second tier's loading tier cargo 210 to also be flat.

(From the second paragraph onwards)
FIG. 9 is a schematic diagram showing loading of cargo from the second to fourth levels in the first embodiment of the present invention. The side frames 101 of the car truck 100 are configured to widen upward. Therefore, as the height increases from the second level to the third level, the fourth level, and so on to the Nth level, the width of the car truck 100 at that height increases. Therefore, when moving to the upper levels, the loading mechanism 20 can load the loading-level cargo 210 in a flat state. In this way, the loading-level cargo 210 can be loaded toward the upper levels as shown in FIG. 9.

Note that in Figure 9, the overall width of the loading tier luggage 210 on the upper tier is larger, but this does not have to be the case; the overall width of the loading tier luggage 210 loaded on the first tier to the Nth tier may be the same.

As described in Figures 7 to 9, the luggage loading device 1 of the present invention loads loading-level luggage 210 from the first level to the Nth level on the bottom plate 102. At this time, if the luggage exceeds the width, the central luggage 200 is raised higher than the luggage on both sides to narrow the width of the bottom side when loading. The luggage 200 on a convex level is pressed down and flattened when the next level of loading-level luggage 210 is loaded. By loading in this manner, even when loading loading-level luggage 210 onto a car dolly 100 that exceeds the width, work such as manually adjusting and pressing it down is not required, and loading can be performed by a mechanical luggage loading device.

(Loading mechanism configuration and functional description)

The configuration and function of the loading mechanism 20 will be explained.

Figure 10 is a schematic diagram of the loading mechanism in embodiment 1 of the present invention. The loading mechanism 20 places multiple luggage items 200 contained in the loading-stage luggage items 210 transferred by the transfer mechanism 40, and loads the loading-stage luggage items 210 onto the car cart 100 by inserting it into the car cart 100. The loading mechanism 20 also performs an operation of withdrawing the placement section 2 from the car cart 100, so that after loading the loading-stage luggage items 210, the operation can be changed to loading the loading-stage luggage items 210 corresponding to the next stage.

The loading mechanism 20 comprises a placement unit 2, a movement control unit 3, and a loading control unit 4. The placement unit 2 places a row of loading-stage luggage 210 corresponding to the first to Nth stages of the car dolly 100 described in Figure 7 and elsewhere. Multiple luggage 200 are placed along the width direction of the placement unit 2, and this row of multiple luggage 200 constitutes the loading-stage luggage 210. These are then stacked in positions such as the first stage and second stage of the car dolly.

The loading section 2 comprises a first loading platform 21 in the center, and a second loading platform 22 and a third loading platform 23 on either side of the first loading platform 21. The first loading platform 21 and the second loading platform 22 are connected, and the first loading platform 21 and the third loading platform 23 are also connected. A piece of luggage 200 is placed on each of the first loading platform 21, the second loading platform 22, and the third loading platform 33, and thus a load-stage luggage 210 consisting of multiple pieces of luggage 200 is placed on the entire loading section 2.

Furthermore, the placement section 2 is inserted into the car dolly 100 and cargo is loaded onto the car dolly 100. The placement section 2 corresponds to the width of the car dolly 100, and when the placement section 2 is inserted into the car dolly 100 and the loaded cargo 200 is removed, the loading stage cargo 210 is loaded onto the car dolly 100. By repeatedly inserting and removing the placement section 2, the loading of the loading stage cargo 210 onto the first to Nth stages progresses.

In other words, the overall width of the multiple pieces of luggage 200 placed on the loading section 2 is greater than or less than the width of the car trolley 100.

The mounting unit 2 includes a first mounting table 21 to a third mounting table 23. As shown in FIG. 11, each of the first mounting table 21 to the third mounting table 23 is movable (movement refers to movement up and down and movement left and right). FIG. 11 is a schematic diagram showing the function of the mounting unit in this embodiment of the present invention.

The first platform 21 is capable of placing luggage 200 on it and is also capable of moving up and down. The platform 2 is equipped with a vertical drive unit 31 that enables the first platform 21 to move up and down. The movement control unit 3 operates the vertical drive unit 31 to move the first platform 21 up and down.

The second platform 22 is capable of placing luggage 200 and moving left and right. The platform 2 is equipped with a left-right drive unit 32 that enables left-right movement of the second platform 22. The movement control unit 3 operates the left-right drive unit 32 to move the second platform 22 left and right.

The third platform 23 is capable of placing luggage 200 and moving left and right. The platform 2 is equipped with a left-right drive unit 33 that enables left-right movement of the third platform 23. The movement control unit 3 operates the left-right drive unit 33 to move the third platform 23 left and right.

When the first platform 21 moves upward with luggage 200 placed on it, the luggage 200 placed on the first platform 21 moves upward. At this time, the second platform 22 and the third platform 23 do not move upward, so only the luggage 200 placed on the first platform 21 moves upward.

In addition, the second platform 22 moves left and right to approach the first platform 21, and the third platform 23 also moves left and right to approach the first platform 23. In this way, the multiple packages 200 placed on the first platform 21 to the third platform 23 are arranged in a curved pattern as shown in Figure 3.

Figure 12 is a schematic diagram showing how the movement of the first to third loading platforms 21 to 23 causes the cargo 200 on the loading platform 210 to assume a curved shape.

When the overall width of the multiple load-stage luggage items 210 placed on the placement section 2 exceeds the width of the car dolly 100 for the loading stage, they cannot be loaded onto the car dolly 100 in the state shown on the left in Figure 12 (multiple luggage items 200 are parallel). In this overwidth state, the width of the placement section 2 is reduced by moving the first placement platform 21 upward and bringing the second placement platform 22 and the third placement platform 23 closer to the first placement platform 21, as shown on the right in Figure 12. In other words, the overall width of the bottom of the load-stage luggage items 210 is reduced, making them possible to insert them to fit the width of the car dolly 100. The load-stage luggage items 210 assume a curved shape as shown on the right in Figure 12.

The loading control unit 4 controls the insertion of the placement unit 2 into the car dolly 100 or the removal of the placement unit 2 from the car dolly 100. The placement unit 2 on which the cargo 200 is placed is inserted into the car dolly 100. After insertion, the loading stage cargo 210 is lowered from the placement unit 2 onto the car dolly 100. The loading control unit 4 removes the placement unit 2 from the car dolly 100 after the loading stage cargo 210 has been removed, i.e., returns it.

The loading control unit 4 controls the loading and unloading of the placement unit 2 onto the car dolly 100. As shown in FIG. 9, the luggage loading device 1 loads the loading-level luggage 210 from the bottom plate 102 of the car dolly 100 upward in the order of first level, second level, third level, etc. In response to this, the loading control unit 4 moves the placement unit 2 to the first level, second level, third level, etc. position.

To summarize the above, we have the following:

A plurality of luggage 200 (loading-stage luggage 210) corresponding to the first tier are placed on the placement section 2. At this time, luggage 200 is placed on each of the first placement table 21, second placement table 22, and third placement table 23 that make up the placement section 2. At least one of the movement control section 3 and the loading control section 4 compares the overall width of the loading-stage luggage 210 (which may be measured using the width of the placement section 2) with the width of the tier on the car trolley 100 on which the loading-stage luggage 210 is loaded (determined using a measuring device such as a sensor, or from pre-programmed numerical values).

If the result of this comparison indicates that the load exceeds the width limit, the movement control unit 3 moves the first platform 21 upward and moves the second platform 22 and the third platform 23 toward the first platform 21, as shown in Figure 9. In other words, the load-tier cargo 210 corresponding to the first tier becomes arched on the platform 2.

This arched shape reduces the width of the bottom of the loading-stage cargo 210, making it possible to insert it into the first stage of the car trolley 100 even if it exceeds the width limit. In this insertable state, the loading control unit 4 inserts the placement unit 2 into the first stage position. That is, the placement unit 2 is inserted in an arched shape. The inserted placement unit 2 places the loading-stage cargo 210 in the first stage position. The loading control unit 4 simply tilts the placement unit 2 to lower and stack the cargo 200.

When the loading control unit 4 has finished loading the loading-stage cargo 210 onto the car cart 100, it pulls out (pulls back) the placement unit 2. This allows the placement unit 2 to place the loading-stage cargo 210 corresponding to the next stage.

Next, the loading unit 2 places the loading-stage cargo 210 corresponding to the second stage. At this time, the overall width of the loading-stage cargo 210 is compared with the width of the car dolly 100 at the second stage to determine whether it is overwidth or underwidth. If it is overwidth, the movement control unit 3 moves the first loading platform 21 upward and moves the second loading platform 22 and the third loading platform 23 toward the first loading platform 21, just as in the case of the first stage.

On the other hand, if the width is less than the specified width, the movement control unit 3 keeps the first platform 21, the second platform 22, and the third platform 23 parallel, and causes the loaded cargo 210 to be parallel (left side of Figure 12). In this state, the loading control unit 4 inserts the platform 2 into the second stage of the car truck 100. After insertion, the loaded cargo 210 is placed from the platform 2 into the second stage of the car truck 100.

At this time, the second-tier loading stage luggage 210 is placed on top of the first-tier loading stage luggage 210. The first-tier loading stage luggage 210 is convex. The loading control unit 4 operates the placement unit 2 to press down on the first-tier loading stage luggage 210 from above. It does so by applying pressure. This is because when the loading stage luggage 210 is stacked on the second tier, the placement unit 2 is on top of the first-tier luggage 200.

This pressing force causes the curved first-tier load cargo 210 to approach a parallel state. The weight of the second-tier load cargo 210 is also added, causing the cargo to become parallel. This is shown in Figures 8 and 9. The same effect as manually pushing and packing cargo is achieved by the machine.

The same applies to the third tier and beyond. As a result, loading tier cargo 210 can be loaded on multiple tiers as shown in Figure 9. This prevents gaps from forming as in conventional technology. It also reduces the burden of manually pressing down and packing the cargo tightly to prevent gaps.

The car dolly 100 is stacked with the first, second, third, and Nth tiers, starting from the bottom plate 102 and proceeding upward. In any of the tiers from the first tier onwards, if the tier exceeds the width limit, the load-tier luggage 210 placed on the loading section 2 is curved as described above. In the tiers that are equal to or smaller than the width limit, the load-tier luggage 210 placed on the loading section 2 remains parallel. This allows luggage 200 to be loaded in a way that is appropriate for each tier.

The first to Nth stages include at least one of an over-width state and an under-width state. In the over-width state, the load-carrying-stage cargo 210 on the loading section 2 is curved, and in the under-width state, the load-carrying-stage cargo 210 on the loading section 2 is parallel.

(Loading using luggage loading device)
13 is a schematic diagram showing the process of loading luggage onto a car truck by the luggage loading device 1 according to the first embodiment of the present invention. By performing the operations described above, the luggage loading device 1 loads luggage 200 onto the car truck 100 in the first to Nth layers.

As shown in Figure 13, the luggage 200 is loaded in the order of 1 to 11. In the first tier, the overall width of the loading-tier luggage 210 exceeds the width. In this case, in the loading section 2, the first loading platform 21 moves upward, and the second loading platform 22 and the third loading platform 23 move closer to the first loading platform 21. As a result, the loading-tier luggage 210 in the first tier becomes arched, as shown by 1 in Figure 13.

In the second tier, the load-carrying cargo 210 is also loaded in a curved position because it exceeds the width. In the third tier, the load-carrying cargo 210 is loaded in a parallel position because it is below the width.

In the over-width state, the bottom of the first platform 21 is higher than the bottom of the second platform 22 and the third platform 23. Placing luggage in this manner causes the load-stage luggage 210 to become uneven. This is because the bottom of the luggage 200 placed on the first platform 21 is higher than the bottom of the luggage 200 placed on the second platform 22 and the third platform 23.

When the width is less than the specified value, the bottom surfaces of the first platform 21, second platform 22, and third platform 23 are at approximately the same height. This approximately uniform height allows the placed luggage 200 to be parallel. The movement control unit 3 controls the platform 2 in this way, allowing the loading stage luggage 210 to be loaded in accordance with the stage. The loading control unit 4 also adjusts the height of the platform 2 to the height of the stage to be loaded. In this way, the loading stage luggage 210 is loaded on the first to third stages.

In Figure 13, after the first loading stage cargo 210 has been loaded, the arched loading stage cargo 210 is now parallel. Before loading the upper loading stage cargo 210, the loading section 2 presses down the arched cargo 200 to make it parallel. Alternatively, as explained in Figures 7 to 9, when loading the upper loading stage cargo 210 on the arched loading stage cargo 210, the loading section 2 may press down the arched cargo 200 to make it parallel.

In this way, in the process of loading the loading-stage cargo 210 in the order of tiers 1 to 3, loading-stage cargo 210 is loaded in correspondence with the over-width tiers and the under-width tiers. This allows the final required number of loading-stage cargo 210 to be loaded onto the car dolly 100. Furthermore, since the over-width tiers can also be loaded neatly in the width direction, loading occurs without any gaps.

This prevents problems such as luggage falling during transport.

Loading onto the cart 100 as shown in Figure 13 is performed by the loading control unit 4.

The loading control unit 4 loads the placement units 2 carrying cargo corresponding to each of the first to Nth levels onto the car dolly 100. At this time, while the loading-level cargo 210 is placed on the placement unit 2, the loading control unit 4 inserts the placement unit 2 with the loading-level cargo 210 on it into the car dolly 100. As a result, the loading-level cargo 210 is loaded onto the car dolly 100. The loading control unit 4 then pulls the placement unit 2 out of the car dolly 100.

The loading control unit 4 also controls the placement unit 2 to press down on the arched loading stage cargo 210. This pressing down allows the arched loading stage cargo 210 to be made parallel.

As described above, the luggage loading device 1 of embodiment 1 can prevent gaps from forming between adjacent luggage items 200 on the car dolly 100. Furthermore, to prevent gaps from forming, the workload of manually pushing luggage items tightly together can be reduced.

(Embodiment 2)

Next, we will explain embodiment 2. In embodiment 2, we will explain details of the removal mechanism 30 and the movement mechanism 40.

(luggage storage area)
4, the luggage storage area 220 stores a plurality of luggage 200. The luggage 200 is in the form of a cardboard box for storing items. The luggage 200 may be not only a cardboard box but also a box-like object of another shape.

A large number of pieces of luggage 200 are stored in the luggage storage area 220, and are removed by the removal mechanism 30. At this time, the removal mechanism 30 removes the pieces of luggage 210 in the form of loading tier luggage that corresponds to the first tier of loading onto the car dolly 100, etc. In other words, if the number of pieces of luggage 200 in the loading tier luggage 210 is five, the removal mechanism 30 removes five pieces of luggage 200.

For this reason, in the luggage storage area, luggage 200 may be stored in rows of five luggage 200 as a standard. Of course, the size of the car cart 100, the size of the luggage 200, and the number of luggage that can be loaded on the same car cart 100 may differ depending on the tier, such as the first tier...Nth tier, etc. For this reason, the luggage storage area 220 does not have to store a number of luggage that matches the number of loading tier luggage 210.

The luggage storage area 220 may also be connected to a supply function that supplies the next luggage 200. The luggage 200 may be supplied by a conveyor or the like, by human power, or by transport machinery. In this way, the luggage storage area 220 stores the luggage 200 required to be loaded onto the car cart 100.

(Removal mechanism)
The take-out mechanism 30 takes out the luggage 200 from the luggage storage area 220. The taken-out luggage 200 is transported to the loading mechanism 20 via the transfer mechanism. The take-out mechanism 30 includes a moving frame plate or a robot arm, etc., and can take out the luggage 200 from the luggage storage area 220 to the transfer mechanism 40.

Alternatively, rollers may be provided between the luggage storage area 220 and the transfer mechanism, and the luggage 200 may be handed over to the transfer mechanism by these rollers.

Here, it is preferable that the removal mechanism 30 removes a number of luggage 200 corresponding to the number of loading-stage luggage 210 from the luggage storage area 220. Figure 6 shows the state in which the loading-stage luggage 210 (the number of luggage 200 corresponding to the number to be loaded on the loading stage of the car dolly 100) is removed and transferred by the transfer mechanism 40.

By having the removal mechanism 30 remove the number of packages 200 corresponding to the number of loading-stage packages 210, the work of the transfer mechanism 40 and loading mechanism 20 can be made more efficient. This is because the loading mechanism 20 processes the loading-stage packages 210 as a single unit.

For this reason, the removal mechanism 30 may be equipped with a sensor that detects the number of luggage 200 and the width corresponding to the loading stage luggage 210. Alternatively, it may be pre-programmed and remove the number of luggage 200 corresponding to the loading stage luggage 210 according to this programming. Of course, the worker may adjust the number of luggage 200 to be removed by operating an operation switch or the like as necessary.

The removal mechanism 30 is connected to the transfer mechanism 40, and the removed luggage 200 is transferred directly by the transfer mechanism 40. Figure 6 also shows the transfer by this transfer mechanism 40.

(transfer mechanism)
As shown in Fig. 6, the transfer mechanism 40 transfers the luggage 200 removed by the removal mechanism 30 to the loading mechanism 20. The luggage 200 may be transferred by a conveyor mechanism such as a roller conveyor or a belt conveyor as shown in Fig. 66. Alternatively, the luggage 200 may be transferred as a single unit in a number corresponding to the number of luggage 210 on the loading stage.

By transporting these as a single unit, the loading mechanism 20 can efficiently load and process the luggage 200 transported by the transport mechanism 40 as is. This is because the loading mechanism 20 only needs to handle the number of luggage 200 sent as a unit.

Figure 14 is a side view showing the movement of luggage from the transfer mechanism to the loading mechanism in embodiment 2 of the present invention.

The transfer mechanism 40 transfers the luggage 200 and then hands it over to the loading mechanism 20. Here, the transfer mechanism 40 includes a transfer means 41 that transfers the luggage 200 corresponding to the loading stage luggage 210, and a loading means 42 that places the luggage 200 on the loading section 2 of the loading mechanism 20. Figure 14 shows this configuration.

The transport means 41 transports the luggage 200. For example, it has a conveyor mechanism and transports the luggage 200 to a position corresponding to the loading section 2. Figure 6 shows the state in which a roller conveyor is transporting the luggage 200. Once transported to this position, the luggage 200 is handed over to the loading mechanism 20.

The placement means 42 places the luggage 200 that has arrived via the transfer means 41 onto the placement section 2 of the loading mechanism 20. In Figure 14, a push-out mechanism that pushes the luggage 200 onto the placement section 2 is provided, and this plays the role of the placement means 42. The transfer directions of the loading mechanism 20 and the transfer mechanism 40 intersect. Therefore, the placement means 42, which is a push-out mechanism or the like, moves the luggage 200 in a direction that intersects with the transfer direction of the transfer means 41.

Figure 14 shows movement in this intersecting direction. The luggage 200 carried by the transfer means 41 is pushed from the right to the left in Figure 14 (intersecting the transfer direction of the transfer means 41). This pushing causes the transferred luggage 200 to be placed on the loading section 2.

The loading means 42 may also hold multiple units 200 corresponding to the loading stage units 210 by clamping them from both sides, as shown in Figure 14, and move them to the loading section 2. By clamping them from both sides, it is also preferable to adjust the widthwise position of the multiple units 200 corresponding to the loading stage units 210.

In addition, it is also preferable to adjust the forward-backward position of the cargo 200 on the loading stage cargo 210 by placing a member behind the cargo 200.

After being positioned as described above, the luggage 200 is placed on the loading section 2. This ensures that each piece of luggage 200 placed on the loading section 2 is placed in the appropriate position. From this position, the luggage is loaded onto the cart 100, allowing it to be loaded in an appropriate and neat position.

The cargo 200 of the loaded cargo 210, whose position has been adjusted, is placed on the loading section 2. As described in the first embodiment, the loading section 2 can be curved or parallel as needed. After this change in configuration, the loading section 2 is inserted into the car dolly 100 and the loaded cargo 210 is loaded.

(Up and down control of the placement section)
15 is a side view illustrating the vertical movement of the placement unit relative to the car bogie in the second embodiment of the present invention. The diagram is based on the relative relationship between the car bogie 100 and the loading mechanism 20.

The loading control unit 4 moves the placement unit 2 up and down to positions corresponding to the first, second, ... Nth levels of the car dolly 100. Figure 15 shows this up and down movement. This up and down movement of the placement unit 2 allows the loading level baggage 210 to be loaded appropriately onto the level to be loaded.

Furthermore, the placement means 42 may also move up and down in accordance with the up and down movement of the placement unit 2. In other words, the loading stage luggage 210 transferred by the transfer means 41 is placed on the placement means 42. The placement means 42 itself may move up and down, and the placement unit 2 may also move up and down in accordance with this. By moving the placement unit 2 up and down in this way, the loading stage luggage 210 can be loaded onto the desired stage.

(Overall picture)
16 is a perspective view of the vicinity of the loading mechanism in the second embodiment of the present invention. The figure shows the state in which the baggage 200 transferred by the transfer mechanism 40 is loaded from the loading section 2 onto the car cart 100, as viewed from the car cart 100 side.

The loading mechanism 20 is equipped with a frame 52 and control box 51 as needed. The control box 51 houses the base and operating mechanisms required for operation by the operator.

The loading stage cargo 210 transferred by the transfer means 41 is placed on the loading section 2 by the loading means 42. As explained in the first embodiment, the loading section 2 causes the loading stage cargo 210 to curve up when it exceeds the width limit. Figure 16 shows this state. Furthermore, this curved loading stage cargo 210 is loaded onto the first level, the lowest level, of the car dolly 100.

The second-tier cargo 210 is then loaded on top of the first-tier cargo 210, which has been arched. During this loading process, the arched state is flattened, and ultimately, the cargo 200 is loaded flat in multiple tiers. This results in the state shown on the right side of Figure 9.

As described above, the luggage 200 removed from the luggage storage area 220 by the removal mechanism 30 and transferred by the transfer mechanism 40 are loaded sequentially onto each stage of the car truck 100 by the loading mechanism 20. Finally, the car truck 100 loaded with the required luggage 200 is handed over to the next stage.

The cargo loading device for the car truck described in the embodiment is an example that illustrates the spirit of the present invention, and includes modifications and alterations that do not deviate from the spirit of the present invention.
