Description

[Technical Field]

[0001] The present invention relates to a device for loading cargo onto a car truck, which loads cargo containing boxed articles onto a car truck in a state with good loading efficiency. [Background technology]

[0002] As people's tastes become more diverse, many kinds of goods are produced. These various goods are produced by various manufacturers, whether in Japan or overseas, in various regions. As a result, many goods need to be delivered from various regions to other regions.

[0003] These items are then delivered by manufacturers to retailers, wholesalers, etc. Alternatively, they may be picked up by a delivery company, which then delivers the various items together.

[0004] Internet shopping is also booming. Customers are no longer visiting brick-and-mortar stores (supermarkets and department stores) to purchase and take home goods; instead, they are ordering goods online and paying electronically. However, even with this type of Internet shopping, the ordered and paid-for goods still need to be delivered to the purchaser.

[0005] In such cases, various goods are delivered from manufacturers, retailers, etc. to purchasers, or are collected and delivered by delivery companies. 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.

[0006] Of course, there are many situations where multiple boxes containing the same type of product must be loaded onto a cart. There are many cases where multiple cardboard boxes containing the same product must be loaded onto a cart.

[0007] Actors with various roles, such as manufacturers, distributors, and delivery companies, deliver goods to where they are needed.

[0008] As mentioned above, goods are often not delivered as they are, but rather stored in boxes such as cardboard boxes and delivered. In other words, goods are delivered as parcels in boxes. Delivery management is carried out by attaching barcodes, two-dimensional barcodes, etc. to the boxes.

[0009] Here, the boxed goods are loaded onto trucks, freight trains, ships, etc. for delivery. At this time, the boxed goods are loaded onto trucks, etc. in a cart, etc., in order to improve work efficiency. This is because loading a large number of goods together onto trucks, etc., improves delivery efficiency.

[0010] 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 the basket cart, transported by truck or other means, can simply be handed over to the delivery destination.

[0011] As such, there is a need for efficient loading for delivering packages containing a wide variety of items. Technologies related to this have been proposed (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0012] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-37992 Summary of the Invention [Problem to be solved by the invention]

[0013] Patent Document 1 discloses an automatic loading system including a product case transport step of picking out the relevant product cases 12 based on shipping instruction information and transporting them on a belt conveyor (transport means) 14; a product case sorting step of recognizing the characteristic information of the product cases 12 and sorting and transporting them to the storage transport means 20 corresponding to the characteristic information; a cart truck moving step of moving a cart truck 22 used to load the product cases 12 and transport them to the destination to a loading area 26 for the product cases 12; a product case loading step of creating loading data from the shipping instruction information, the characteristic information of the product cases 12 and the loading state of the product cases 12 and loading the product cases 12 onto the cart truck 22 in a predetermined position and order based on the shipping instruction information; and a cart truck discharging step of discharging each cart truck 22 from the loading area 26.

[0014] However, in order to load products onto a transport vehicle using an automatic mechanism, it is necessary to create a distance between the products loaded onto the transport vehicle in order to ensure an operating area required for the mechanism to operate. Alternatively, as a result of loading products using an automatic mechanism, a distance inevitably occurs between the products.

[0015] Furthermore, the width of the transport vehicle is not proportional to the width of the product, so when multiple products are loaded horizontally on the transport vehicle, gaps may inevitably occur.

[0016] In this way, if there is a gap between the packages loaded on the transport vehicle, there is a problem that the packages may fall over during transportation by truck, etc. If the packages fall over, it is natural that problems such as damage to the products and goods stored therein may occur.

[0017] To prevent the dolly from tipping over, it is necessary to wrap the loaded cargo in film to secure it in place, which is costly and time-consuming, and also leads to problems such as the hassle of unloading the cargo after delivery.

[0018] As described above, conventional technologies such as Patent Document 1 disclose a technique for automatically loading cargo onto a cart, but they have problems such as (1) gaps occurring between the cargo items, (2) cargo items tipping over when transported with gaps occurring, (3) reduced efficiency in loading cargo onto the cart, and (4) increased effort and costs required to take measures to prevent tipping over.

[0019] Furthermore, at actual work sites, a line of cargo would be too wide to fit into a truck, so the work was done by hand, resulting in a so-called "crammed" construction, so that the width of the truck matched the overall width of the cargo. Naturally, all of the placement, loading, and proper loading was done by hand, which created the problem of not being able to place or load cargo by machine in the first place.

[0020] Furthermore, at actual work sites, if a skilled worker were to load a line of cargo that would not fit into a machine's overall width, they could do so by carefully checking the load and packing it in tightly so that the width of the cart and the overall width of the cargo matched. Naturally, all of the placing, loading, and proper loading was done manually, which presented the problem of not being able to place or load the cargo by machine in the first place.

[0021] In addition, loading large quantities of cargo onto a cart by hand is difficult due to issues such as labor and time. As mentioned above, large quantities of cargo must be loaded onto the cart one after another, which is difficult to do manually. Furthermore, loading cargo in a way that leaves gaps between the cargo will lead to continuous problems such as cargo shifting during transport. Alternatively, loading would require a combination of machinery and manual labor, which is also unrealistic.

[0022] That is, in addition to the above-mentioned problems, the prior art has also had the problem that a large amount of cargo cannot be efficiently loaded onto a car truck.

[0023] In view of the above-mentioned problems, an object of the present invention is to provide a device for loading luggage onto a car truck, which loads luggage onto a car truck efficiently and reduces gaps between luggage pieces. [Means for solving the problem]

[0024] In view of the above problems, the device for loading luggage onto a car truck of the present invention is a device for loading luggage onto a car truck that loads luggage onto a first stage, a second stage, ..., an Nth stage upward from a bottom plate of the car truck, and a take-out mechanism that takes out luggage corresponding to the first tier, second tier, to 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 section 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 stage, horizontal movement of the second stage, and horizontal movement of the third stage; 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 cart (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 in a parallel state; 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. [Effects of the Invention]

[0025] The device for loading luggage onto a car truck of the present invention can efficiently load the number of luggage that can be loaded onto the car truck. By improving loading efficiency, it is possible to improve luggage delivery capacity and reduce delivery costs.

[0026] Furthermore, 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 to wrap the entire cargo in film to prevent tipping over due to gaps.

[0027] In addition, by being able to load an optimized number of items according to the shape and size of the cart, total costs and environmental impact can be reduced. [Brief explanation of the drawings]

[0029] A device for loading luggage onto a car bogie according to a first aspect of the present invention is a device for loading luggage 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, to 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 section 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 stage, horizontal movement of the second stage, and horizontal movement of the third stage; 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 cart (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 in a parallel state; 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.

[0030] This configuration allows cargo to be loaded across the entire width of the cart without any gaps, preventing gaps that could cause cargo to collapse during transport. It also reduces the workload of manually packing cargo.

[0031] In a device for loading luggage onto a car truck according to a second aspect of the present invention, in addition to the features of the first aspect, in the over-width 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.

[0032] This configuration allows the cargo to be loaded onto the car dolly even if it exceeds the width limit. In particular, the width of the bottom part of the loading stage cargo becomes smaller than when it is in its original state, so it can be inserted even in the narrow bottom of the car dolly. After being inserted, it can be loaded by pressing down from above and pushing it in.

[0033] 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.

[0034] This configuration allows cargo to be loaded even when it exceeds the width of the vehicle. In particular, automatic loading is possible using a mechanical cargo loading device, rather than manual loading.

[0035] 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.

[0036] This configuration allows cargo to be stacked in stages.

[0037] In a fifth aspect of the present invention, in addition to the fourth aspect, the loading control unit In accordance with inserting the placing section into the car cart at the upper stage of the stage 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.

[0038] This configuration allows cargo that is packed in a curved shape to be made parallel (flat).

[0039] In a sixth aspect of the present invention, in addition to any one of the first to fifth aspects, the loading control unit sets the storage section to a height at which luggage is loaded on the first to Nth levels.

[0040] This configuration allows cargo to be loaded in stages.

[0041] In the seventh invention of the present invention, in addition to any one of the first to sixth inventions, the removal mechanism transfers a number of luggage corresponding to the loading level from the luggage storage area to the transfer means as loading level luggage.

[0042] This configuration allows the luggage loaded by the loading mechanism to be transferred in sequence, and also allows the luggage in the luggage storage area to be loaded onto the car cart.

[0043] In the device for loading luggage onto a car truck according to an eighth aspect of the present invention, in addition to any one of the first to seventh aspects of the present invention, the transfer mechanism 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.

[0044] With this configuration, the number of load-stage cargoes corresponding to the load stage is transferred and placed on the placement section of the loading mechanism. As a result, the load-stage cargoes transferred by the transfer mechanism are connected so as to be loaded onto the car cart by the loading mechanism.

[0045] In the device for loading luggage onto a car cart according to the ninth aspect of the present invention, in addition to the eighth aspect, the transfer means has a conveyor mechanism and transfers the loading stage luggage to a position corresponding to the placement section.

[0046] This configuration allows for efficient transport of luggage.

[0047] In the luggage loading device for a car trolley according to the tenth invention of the present invention, in addition to the ninth invention, the loading means places the loading stage luggage on the loading section by moving it in a direction intersecting the conveyor mechanism.

[0048] This configuration allows for loading by the loading mechanism.

[0049] In the device for loading luggage onto a car truck according to an 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.

[0050] This configuration allows the items to be loaded in the correct position and alignment when inserted from the loading section onto the cart. Whether the items are arched or parallel, they are loaded in an optimally adjusted manner to fit the width of the cart.

[0051] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0052] (Analysis by the inventor) The inventor analyzed the gaps that occur when loading luggage onto a cart using conventional technology as follows. Figure 1 is a schematic diagram showing the state of luggage loaded onto a cart using conventional technology, 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). For this reason, 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.

[0053] If you try to fit another item into this remaining space, you will need to force it in using human or mechanical means, which increases the amount of work required.

[0054] On the other hand, if multiple items are loaded with sufficient width, gaps will form between the items, as shown in Figure 2. Figure 2 is a schematic diagram showing how items are loaded onto a cart using conventional technology. In both cases shown in Figure 1 and Figure 2, the gaps raise the concern that the items may tip over when the loaded cart is transported by a truck or other vehicle.

[0055] Of course, as mentioned above, inserting another load and then manually or mechanically pushing the load to eliminate the gap increases the effort and cost. Based on this analysis, the inventor has developed a load loading device that efficiently loads multiple loads to fit the width of the car dolly.

[0056] In particular, although it is not impossible to cram the items in tightly by hand, this increases the workload of the workers. Of course, this requires additional manpower, making automation of the loading process difficult. Furthermore, manual work also increases the time required for the work.

[0057] (Embodiment 1)

[0058] (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 a car cart loaded with luggage in the luggage loading device 1.

[0059] The luggage loading device 1 loads luggage 200 on the first, second,... Nth tiers from the bottom plate of the car truck 100 upward. As shown in Fig. 5, the luggage 200 on the first tier is loaded from the bottom plate of the car truck 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 Fig. 5, the luggage 200 loaded on the first to Nth tiers are in a state where multiple luggage 200 are lined up horizontally.

[0060] 5 is a front view showing a state in which luggage is loaded on the car truck in the first embodiment 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, to Nth tier will be referred to as "loading tier luggage" as necessary.

[0061] The luggage loading device 1 includes a removal mechanism 30, a transfer mechanism 40, and a loading mechanism 20.

[0062] The take-out mechanism 30 takes out luggage 200 corresponding to the first tier, second tier, through Nth tier from the luggage storage area 220 that stores a plurality of luggage 200. A large number of luggage 200 in the form of boxes such as cardboard boxes are stored in the luggage storage area 220. New luggage 200 may also be carried into the luggage storage area 220 one after another.

[0063] The take-out mechanism 30 takes out the loading-stage luggage from the luggage storage area 220. It delivers it to the transfer mechanism 40, which ultimately loads the loading-stage luggage onto the car truck 100.

[0064] That is, the luggage loading device 1 has a function of moving the luggage 200 from the luggage accommodation area 220 to the car truck 100 and loading it thereon.

[0065] 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.

[0066] Fig. 6 is a perspective view showing the operation of the transfer mechanism in the first embodiment of the present invention. The transfer mechanism 40 transfers the loading stage luggage 210 as shown in Fig. 6. The number of luggage 200 included in the loading stage luggage 210 is determined by the comparison between the width of the car cart 100 and the luggage 200. The removal mechanism 30 removes luggage 200 corresponding to this determined number all at once and hands them over to the transfer mechanism 40 in the form of loading stage luggage 210.

[0067] The transfer mechanism 40 delivers the loading stage baggage 210 to the loading mechanism 20. By delivering the baggage 200, the loading mechanism 20 can load the baggage 200 onto the car cart 100 in the state of the loading stage baggage 210.

[0068] The loading mechanism 20 loads the load-tier luggage 210 from the bottom plate of the car truck 100 upward to positions corresponding to the first tier, second tier, to Nth tier. As shown in Fig. 5, the loading mechanism 20 loads the luggage 200 one by one onto the car truck 100.

[0069] The car truck 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 truck 100 thereon.

[0070] In this way, the luggage loading device 1 can cover the entire process from carrying the loaded car cart 100 from the luggage storage area 220 to carrying it out.

[0071] (Loading flow of luggage by loading mechanism 20)

[0072] 7 to 9, the flow of loading luggage onto the car cart by the loading mechanism 20 will be described. First, the loading flow (loaded state) will be described. As explained using FIGS. 1 and 2, etc., in the luggage loading device 1, the width of the loading stage luggage 210 can exceed the lateral width of the car cart 100 ("over-width state"). Even under such a premise, the luggage can be loaded so that it fits neatly into the car cart 100.

[0073] (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 cart in an embodiment of the present invention. Fig. 7 shows the state in which the car cart 100 is viewed from the front (the side that is open for loading luggage 200). The same is true for Figs. 8 to 9. 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 cart 100.

[0074] At this time, multiple cargo items 200 are loaded in a state (loading-stage cargo item state 210) lined up in the width direction of the car cart 100 (lateral direction when viewed from the front in FIG. 7). The overall width of the first-stage loading-stage cargo item 210 may be larger than the width of the area of ​​the car cart 100 corresponding to the first stage (hereinafter referred to as "overwidth state"). FIG. 7 shows this state.

[0075] In this over-width state, the loading mechanism 20 inserts the multiple pieces of luggage 200 into the car truck 100 in a curved shape as shown in Figure 3. The middle piece of luggage 200 is positioned higher than the pieces of luggage 200 on both sides. Due to this positional relationship, the overall width of the bottom side becomes smaller than it should be, and the pieces can be inserted into the car truck 100.

[0076] 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 state as viewed from the front in 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.

[0077] First, the loading mechanism 20 loads the loading-stage cargo 210 onto the first stage. If the cargo exceeds the width limit, the central cargo 200 is raised as shown in FIG. 7, and the first stage cargo 200 is loaded into the car truck 100 in a curved position so as to fit within the width of the car truck 100.

[0078] (1st to 2nd paragraphs) Following Figure 7, Figure 8 is shown. Figure 8 is a schematic diagram showing the loading of luggage from the first level to the second level. By the loading mechanism 20, the luggage 200 in the center is raised, and the luggage 200 on both sides are in a lower position, as shown on the left side of Figure 8, and is loaded onto the car cart 100.

[0079] Next, the state shown on the right side of Fig. 8 is reached. The loading mechanism 20 loads the second-tier loading stage cargo 210 on top of the first-tier loading stage cargo 210. As will be described later, the loading mechanism 20 is provided with a loading section on which the loading stage cargo 210 for each tier is placed. From a state in which the first-tier loading stage cargo 210 is loaded on the car cart 100 as shown on the left side of Fig. 8, the loading stage cargo 210 placed on the loading section is loaded into the second-tier position as shown on the right side of Fig. 8.

[0080] As shown on the right side of Fig. 8, when the second-tier loading-stage cargo 210 is loaded, the loading section presses down on the first-tier loading-stage cargo 210 from above. Due to this pressing down and the weight of the second-tier loading-stage cargo 210, the curved first-tier loading-stage cargo 210 becomes flat, as shown on the right side of Fig. 8.

[0081] Furthermore, when the overall width of the second-stage loading cargo 210 is equal to or less than the width of the car cart 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 cart 100 while remaining in a parallel state.

[0082] As a result, the arched 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 and flat state from the bottom plate 102 to the upper tier.

[0083] Of course, if the second tier also exceeds the width limit, the second tier load 210 will also be loaded in a curved state, just like the first tier. When the third tier load 210 above the second tier is loaded, it will be pressed down from above by the loading section, and the second tier load 210 will also be flattened.

[0084] (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 dolly 100 are configured to widen upward. Therefore, as the height increases from the second level, to the third level, to the fourth level, to the Nth level, the width of the car dolly 100 at that height increases. Therefore, when going 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.

[0085] In Figure 9, the overall width of the loading stage luggage 210 on the upper level is larger, but this is not necessary, and the overall width of the loading stage luggage 210 loaded on the first level to the Nth level may be the same.

[0086] As explained in FIGS. 7 to 9, in the luggage loading device 1 of the present invention, loading-stage luggage 210 is loaded from the first stage to the Nth stage 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 and loaded. The luggage 200 on the arched stage is pressed down and flattened when the loading-stage luggage 210 on the next stage is loaded. By loading in this manner, even when loading a loading-stage luggage 210 onto a car cart 100 that exceeds the width, work such as adjusting and pressing it down by hand is not required, and loading can be performed by the luggage loading device, which is a machine.

[0087] (Loading mechanism configuration and functional description)

[0088] The configuration and function of the loading mechanism 20 will be described.

[0089] 10 is a schematic diagram of the loading mechanism in the first embodiment of the present invention. The loading mechanism 20 places a plurality of luggage 200 included in the loading stage luggage 210 transferred by the transfer mechanism 40, and loads the loading stage luggage 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 210, the operation can be changed to loading the loading stage luggage 210 corresponding to the next stage.

[0090] The loading mechanism 20 includes 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 FIG. 7 and other figures. A plurality of luggage 200 is placed along the width direction of the placement unit 2, and this row of loaded luggage 200 is the loading-stage luggage 210. These luggage are stacked at positions such as the first stage and second stage of the car dolly.

[0091] The placement section 2 comprises a first placement table 21 in the center, and a second placement table 22 and a third placement table 23 provided on either side of the first placement table 21. The first placement table 21 and the second placement table 22 are connected, and the first placement table 21 and the third placement table 23 are also connected. A piece of luggage 200 is placed on each of the first placement table 21, the second placement table 22, and the third placement table 33, and thus a load-stage luggage 210 consisting of a plurality of luggage 200 is placed on the entire placement section 2.

[0092] Furthermore, the placing section 2 is inserted into the car cart 100 and cargo is loaded onto the car cart 100. The placing section 2 corresponds to the width of the car cart 100, and when the placing section 2 is inserted into the car cart 100 and the loaded cargo 200 is lowered, the loading stage cargo 210 is loaded onto the car cart 100. By repeatedly inserting and withdrawing the placing section 2, the loading of the loading stage cargo 210 onto the first to Nth stages progresses.

[0093] That is, the overall width of the plurality of baggage items 200 placed on the placement section 2 is greater than or less than the width of the car cart 100 .

[0094] The mounting section 2 includes a first mounting table 21 to a third mounting table 23. Here, as shown in Fig. 11, each of the first mounting table 21 to the third mounting table 23 is movable (movement means movement up and down and movement left and right). Fig. 11 is a schematic diagram showing the function of the mounting section in the embodiment of the present invention.

[0095] The first platform 21 is capable of placing the luggage 200 thereon and is also capable of moving up and down. The platform 2 is provided 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.

[0096] The second platform 22 is capable of placing the luggage 200 thereon and is also movable left and right. The platform 2 is provided with a left and right drive unit 32 that enables the second platform 22 to move left and right. The movement control unit 3 operates the left and right drive unit 32 to move the second platform 22 left and right.

[0097] The third platform 23 is capable of placing the luggage 200 thereon and is also movable left and right. The platform 2 is provided with a left and right drive unit 33 that enables the left and right movement of the third platform 23. The movement control unit 3 operates the left and right drive unit 33 to move the third platform 23 left and right.

[0098] When the first platform 21 moves upward with the 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.

[0099] In addition, the second platform 22 moves left and right so as to approach the first platform 21, and the third platform 23 also moves left and right so as to approach the first platform 23. In this way, the plurality of luggage 200 placed on the first platform 21 to the third platform 23 assumes an arched shape as shown in FIG.

[0100] FIG. 12 is a schematic diagram showing that the cargo 200 on the loading stage cargo 210 is curved due to the movement of the first to third loading tables 21 to 23. As shown in FIG.

[0101] In an over-width state where the overall width of the multiple loading stage luggage 210 placed on the placement section 2 exceeds the width of the car cart 100 of the stage to be inserted, the luggage cannot be loaded onto the car cart 100 in the state shown on the left in FIG. 12 (multiple luggage 200 are parallel). In this over-width 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 FIG. 12. In other words, the overall width of the bottom of the loading stage luggage 210 is reduced, making it possible to insert the luggage in accordance with the width of the car cart 100. The loading stage luggage 210 assumes a curved shape as shown on the right in FIG. 12.

[0102] The loading control unit 4 controls the insertion of the placement unit 2 into the car cart 100 or the removal of the placement unit 2 from the car cart 100. The placement unit 2 on which the luggage 200 is placed is inserted into the car cart 100. After insertion, the loading stage luggage 210 is lowered from the placement unit 2 onto the car cart 100. The loading control unit 4 removes the placement unit 2 from the car cart 100 after the loading stage luggage 210 has been lowered, i.e., returns it.

[0103] The loading control unit 4 controls the loading and unloading of the placement unit 2 onto and from the car dolly 100. As shown in Fig. 9, the luggage loading device 1 loads the loading-stage luggage 210 from the bottom plate 102 of the car dolly 100 upward in the order of first stage, second stage, third stage, etc. The loading control unit 4 accordingly moves the placement unit 2 to the first stage, second stage, third stage, etc. positions.

[0104] To summarize the above, the following can be said:

[0105] A plurality of luggage 200 (loading-stage luggage 210) corresponding to the first stage is placed on the placement section 2. At this time, the luggage 200 is placed on each of the first placement table 21, the second placement table 22, and the third placement table 23 that constitute 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 based on the width of the placement section 2) with the width of the stage on the car cart 100 on which the loading-stage luggage 210 is loaded (determined by a measuring device such as a sensor, or by a pre-programmed numerical value).

[0106] 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 FIG. 9. In other words, the loading platform baggage 210 corresponding to the first tier becomes arched on the platform 2.

[0107] This arched shape reduces the width of the bottom of the loading stage cargo 210, and even if it exceeds the width limit, it can be inserted into the first stage position of the car trolley 100. 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 unload and stack the cargo 200.

[0108] When the loading control unit 4 has finished loading the loading-stage baggage 210 onto the car cart 100, it pulls out (pulls back) the placement unit 2. This makes it possible for the placement unit 2 to place the loading-stage baggage 210 corresponding to the next stage.

[0109] Next, the placement 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 in an over-width state or an under-width state. If it is in an over-width state, the movement control unit 3 moves the first placement table 21 upward, and moves the second placement table 22 and the third placement table 23 toward the first placement table 21, just as in the case of the first stage.

[0110] Conversely, if the width is less than the predetermined width, the movement control unit 3 keeps the first platform 21, the second platform 22, and the third platform 23 in a parallel state, and causes the loaded load-stage baggage 210 to be placed in a parallel state (left side of FIG. 12). In this state, the loading control unit 4 inserts the platform 2 into the second stage position of the car cart 100. After the insertion, the loading stage baggage 210 is loaded from the platform 2 into the second stage position of the car cart 100.

[0111] 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 arched. The loading control unit 4 operates the placement unit 2 to press down on the first-tier loading stage luggage 210 from above. It presses down 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.

[0112] This pressing force causes the curved first-tier load cargo 210 to approach a parallel state. With the addition of the weight of the second-tier load cargo 210, the cargo becomes parallel, as shown in Figures 8 and 9. The machine performs the same function as manually pushing the cargo into place.

[0113] The same applies to the third tier and beyond. As a result, it is possible to load cargo 210 on multiple tiers as shown in Figure 9. This prevents gaps from forming as in the prior art. It also reduces the burden of manually pressing down and packing the cargo tightly to prevent gaps.

[0114] On the car dolly 100, the cargoes are stacked from the bottom plate 102 upwards in the order of the first tier, second tier, third tier, ... Nth tier. In any of the 1st tier to the Nth tier, in a tier that exceeds the width, the loading-tier cargoes 210 placed on the placement section 2 are arched as described above. In a tier that is equal to or smaller than the width, the loading-tier cargoes 210 placed on the placement section 2 remain parallel. This allows cargoes 200 to be loaded in a way that is appropriate for each tier.

[0115] 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 loading-stage cargo 210 on the placement section 2 is curved, and in the under-width state, the loading-stage cargo 210 on the placement section 2 is parallel.

[0116] (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 in the first embodiment of the present invention. By performing the operations already described, the luggage loading device 1 loads luggage 200 onto the car truck 100 in the first to Nth layers.

[0117] As shown in FIG. 13, the luggage 200 is loaded in the order of 1 to 11. In the first tier, the overall width of the loading-stage luggage 210 exceeds the width limit. 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-stage luggage 210 in the first tier becomes arched as shown in FIG. 13, 1.

[0118] In the second stage, the load-stage cargo 210 is also loaded in a curved state because the load-stage cargo 210 is in an over-width state. In the third stage, the load-stage cargo 210 is loaded in a parallel state because the load-stage cargo 210 is in an under-width state.

[0119] In the over-width state, the bottom surface of the first platform 21 is higher than the bottom surfaces of the second platform 22 and the third platform 23. When luggage is placed in this manner, the loading stage luggage 210 becomes uneven. This is because the bottom surface of the luggage 200 placed on the first platform 21 is higher than the bottom surfaces of the luggage 200 placed on the second platform 22 and the third platform 23.

[0120] In the width or less state, the bottom surfaces of the first platform 21, the second platform 22, and the third platform 23 are at approximately the same height. This approximately same height allows the placed luggage 200 to be in a parallel state. The movement control unit 3 controls the platform 2 in this way, so that the loading stage luggage 210 can be loaded according to 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.

[0121] In Figure 13, after the first loading stage cargo 210 has been loaded, the arched loading stage cargo 210 has become parallel. Before loading the upper loading stage cargo 210, the loading unit 2 presses down the arched cargo 200 to make it parallel. Alternatively, as described in Figures 7 to 9, when loading the upper loading stage cargo 210 on the arched loading stage cargo 210, the loading unit 2 may press down the arched cargo 200 to make it parallel.

[0122] In this way, in the process of loading the loading-stage cargo 210 in the order of the first to third tiers, the loading-stage cargo 210 is loaded in correspondence with the tiers that are in an over-width state and the tiers that are in an under-width state. This allows the final required number of tiers of loading-stage cargo 210 to be loaded onto the car truck 100. In addition, the tiers that are in an over-width state can also be loaded tightly in the width direction, so that the cargo is loaded without any gaps.

[0123] This prevents problems such as luggage falling during transportation.

[0124] Loading onto the car truck 100 as shown in FIG.

[0125] The loading control unit 4 loads the placement units 2, on which cargo corresponding to each of the first to Nth levels is placed, onto the car cart 100. At this time, while the loading stage cargo 210 is placed on the placement units 2, the loading control unit 4 inserts the placement units 2 with the loading stage cargo 210 on them into the car cart 100. As a result, the loading stage cargo 210 is loaded onto the car cart 100. Thereafter, the loading control unit 4 pulls out the placement units 2 from the car cart 100.

[0126] Furthermore, the loading control unit 4 controls the placement unit 2 to press down from above the arched loading stage cargo 210. By pressing down, the arched loading stage cargo 210 can be made parallel.

[0127] As described above, the luggage loading device 1 of the first embodiment can prevent gaps from being generated between adjacent luggage items 200 on the car cart 100. In addition, to prevent gaps from being generated, the workload of manually pushing luggage items tightly together can be reduced.

[0128] (Embodiment 2)

[0129] Next, a description will be given of a second embodiment, in which details of the take-out mechanism 30 and the moving mechanism 40 will be described.

[0130] (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 other box-like shapes.

[0131] A large number of luggage 200 are stored in the luggage storage area 220, and are taken out by the take-out mechanism 30. At this time, the take-out mechanism 30 takes out the luggage 210 in the form of loading stage luggage 210 that matches the first stage of loading onto the car cart 100, etc. In other words, if the number of luggage 200 on the loading stage luggage 210 is five, the take-out mechanism 30 takes out five luggage 200.

[0132] Therefore, in the luggage storage area, the luggage 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, the Nth tier, etc. Therefore, the number of luggage that can be loaded in the luggage storage area 220 does not have to match the number of loading tier luggage 210.

[0133] The luggage storage area 220 may be connected to a supply function for supplying the next luggage 200. The luggage 200 may be supplied by a conveyor or the like, manually, or by a transport machine. In this way, the luggage storage area 220 stores the luggage 200 required to be loaded onto the car cart 100.

[0134] (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 is equipped with 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.

[0135] Alternatively, rollers may be provided between the luggage storage area 220 and the transport mechanism, and the luggage 200 may be handed over to the transport mechanism by the rollers.

[0136] Here, it is preferable that the take-out mechanism 30 take out the number of luggage 200 corresponding to the loading stage luggage 210 from the luggage storage area 220. Fig. 6 shows a 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 cart 100) is taken out and transferred by the transfer mechanism 40.

[0137] The removal mechanism 30 removes the number of packages 200 corresponding to the number of loading-stage packages 210, thereby improving the efficiency of work in the transfer mechanism 40 and loading mechanism 20. This is because the loading mechanism 20 processes the loading-stage packages 210 as a single unit.

[0138] For this reason, the take-out 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, the take-out mechanism 30 may be pre-programmed, and take out the number of luggage 200 corresponding to the loading stage luggage 210 in accordance with this programming. Of course, the worker may adjust the number of luggage 200 to be taken out by operating an operation switch or the like as necessary.

[0139] The take-out mechanism 30 is connected to a transfer mechanism 40, and the taken-out baggage 200 is transferred by the transfer mechanism 40. FIG.

[0140] (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.

[0141] By transporting these as one unit, the loading mechanism 20 can efficiently load the luggage 200 transported by the transport mechanism 40 as it is. This is because the loading mechanism 20 only needs to handle the luggage 200 of the sent unit as it is.

[0142] FIG. 14 is a side view showing the transfer of luggage from the transfer mechanism to the loading mechanism in the second embodiment of the present invention.

[0143] The transfer mechanism 40 transfers the cargo 200 and then hands it over to the loading mechanism 20. Here, the transfer mechanism 40 includes a transfer means 41 that transfers the cargo 200 corresponding to the loading stage cargo 210, and a placement means 42 that places the cargo 200 on the placement section 2 of the loading mechanism 20. Figure 14 shows this configuration.

[0144] 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 placement unit 2. FIG. 6 shows a 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.

[0145] 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 FIG. 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. For this reason, 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.

[0146] Figure 14 shows movement in this intersecting direction. The luggage 200 carried by the transfer means 41 is pushed out in a direction from the right to the left in Figure 14 (intersecting the transfer direction of the transfer means 41). By this pushing, the transferred luggage 200 is placed on the placement section 2.

[0147] 14, the placement means 42 may hold the plurality of units 200 corresponding to the loading stage unit 210 by sandwiching them from both sides and move them to the placement section 2. By sandwiching them from both sides, it is also preferable to adjust the widthwise positions of the plurality of units 200 corresponding to the loading stage unit 210.

[0148] In addition, it is also preferable to adjust the position of the cargo 200 on the loading stage cargo 210 in the front-to-rear direction by applying a member to the rear of the cargo 200.

[0149] After the position is adjusted in this way, the baggage 200 is placed on the placement section 2. As a result, each baggage 200 placed on the placement section 2 is placed in an appropriate state. Since the baggage 200 is loaded onto the car cart 100 from this state, it is possible to load the baggage in an appropriate and neat posture.

[0150] The cargo 200 of the loading stage cargo 210 whose position has been adjusted is placed on the placement section 2. As described in the first embodiment, the placement section 2 can be curved or parallel as needed. After this change in form, the placement section 2 is inserted into the car cart 100 and the loading stage cargo 210 is loaded.

[0151] (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.

[0152] The loading control unit 4 moves the placement unit 2 up and down to positions corresponding to the first, second, through Nth stages of the car dolly 100. Fig. 15 shows this up and down movement. This up and down movement of the placement unit 2 allows the loading stage baggage 210 to be properly loaded onto the stage to be loaded.

[0153] Furthermore, the placing means 42 may also move up and down in accordance with the up and down movement of the placing unit 2. In other words, the loading stage luggage 210 transferred by the transfer means 41 is placed on the placing means 42. The placing means 42 itself may move up and down, and the placing unit 2 may also move up and down accordingly. By moving the placing unit 2 up and down in this way, the loading stage luggage 210 can be loaded onto the desired stage.

[0154] (Overall picture) 16 is a perspective view of the vicinity of the loading mechanism in the second embodiment of the present invention. It shows how the baggage 200 transferred by the transfer mechanism 40 is loaded from the placement section 2 onto the car cart 100, as viewed from the car cart 100 side.

[0155] The loading mechanism 20 includes a frame 52 and a control box 51 as required. The control box 51 accommodates operations by an operator and stores a base and operating mechanism required for the operation.

[0156] The loading stage cargo 210 transferred by the transfer means 41 is placed on the placement section 2 by the placement means 42. As explained in the first embodiment, the placement section 2 makes the loading stage cargo 210 arch in an over-width state. Figure 16 shows this state. Furthermore, this arched loading stage cargo 210 is loaded onto the first stage, the lowest stage, of the car dolly 100.

[0157] The second layer of cargo 210 is then loaded on top of the first layer of cargo 210. During this loading process, the cargo 200 is flattened out, and finally, the cargo 200 is loaded in multiple layers, resulting in the state shown on the right side of Figure 9.

[0158] As described above, the luggage 200 taken out from the luggage storage area 220 by the take-out mechanism 30 and transferred by the transfer mechanism 40 are loaded in turn 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.

[0159] The device for loading luggage onto a car truck described in the embodiment is an example for explaining the gist of the present invention, and includes modifications and alterations within the scope of the gist of the present invention. [Explanation of symbols]
