Description

[Technical field]

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

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

[0003] These items are then distributed by manufacturers to retailers, wholesalers, etc. Alternatively, they may be collected by a shipping company, which then distributes the various items together.

[0004] Internet shopping is also booming. Customers have moved away from the traditional style of visiting brick-and-mortar stores (supermarkets and department stores) to purchase and take home products, and are now ordering products online and paying electronically. Even with this type of Internet shopping, the products that have been ordered and paid for still need to be delivered to the purchaser.

[0005] In such cases, various goods are delivered from manufacturers, retailers, etc. to purchasers. Or, they 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 packed with the same type of goods need to be loaded onto a cart. There are many cases where multiple cardboard boxes packed with the same product need to 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 described above, in many cases, goods are not delivered as is, but are delivered in boxes such as cardboard boxes. In other words, goods are delivered as parcels in boxes. Delivery management is performed by attaching a barcode or a two-dimensional barcode to the box.

[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 cage cart, etc., in order to improve work efficiency. This is because loading a large number of goods together onto trucks, etc., increases delivery efficiency.

[0010] Of course, by loading multiple packages onto a basket cart, the workload and physical strain on the worker is reduced. Another benefit is that the efficiency of unloading the packages after delivery is increased. For example, by loading multiple packages for the same delivery destination onto a basket cart, delivery and work efficiency can be improved. This is because the basket cart, transported by truck or other vehicle, can be simply handed over to the delivery destination.

[0011] Thus, there is a need for efficient loading for the delivery of luggage containing a wide variety of items. Technologies related to this have been proposed (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0012] [Patent Document 1] JP 2015-37992 A 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 corresponding 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 characteristic information of the product cases 12 and sorting and transporting them to a 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 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 in a predetermined position and order on the cart truck 22 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 the transport vehicle using an automatic mechanism, it is necessary to create a distance between the products loaded onto the transport vehicle in order to secure an operating area required for the operation of this mechanism. Alternatively, as a result of loading by the automatic mechanism, a distance is inevitably created between the products.

[0015] 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 are likely to 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 articles stored therein may occur.

[0017] To prevent the dolly from tipping over, it is necessary to wrap the dolly in film while it is loaded with cargo to secure the cargo, etc. This is problematic in terms of cost and effort, as well as the hassle of unloading the cargo after delivery.

[0018] Thus, conventional technologies such as Patent Document 1 disclose a technique for automatically loading luggage onto a cart, but they have problems such as: (1) gaps occurring between the luggage pieces; (2) luggage may tip over when transported with gaps occurring; (3) the efficiency of loading luggage onto the cart decreases; and (4) measures to prevent tipping over require effort and increased costs.

[0019] Also, at the actual site, if a skilled worker was to load a line of cargo that would not fit into the overall width of the machine, he could load it while checking the load and make it so that the width of the cart and the overall width of the cargo matched. Naturally, the placement, loading, and proper loading were all done by hand, and there was also the problem that placement and loading by machine was not possible in the first place.

[0020] In view of the above problems, the present invention has an object to provide a device for loading luggage onto a car cart, which loads luggage onto the car cart efficiently and without generating gaps between luggage pieces. [Means for solving the problem]

[0021] In view of the above problems, the present invention provides a loading device for loading luggage onto a car dolly, the loading device comprising: a loading section having a first loading platform, a second loading platform connected to one side of the first loading platform, and a third loading platform connected to the other side of the first loading platform; 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 the car cart or removing 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 plurality of pieces of luggage placed on the placement section is greater than the width of the car cart (hereinafter referred to as "over-width state"), the movement control unit moves the first placement table upward and moves the second placement table and the third placement table toward the first placement table to make the plurality of loads form a pile; The loading control unit inserts the placement unit into the car cart while the plurality of baggage items on the placement unit are arranged in a pile-like shape, When the overall width of the plurality of luggage placed on the placement section is equal to or less than the width of the car cart (hereinafter referred to as the "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 cart while the plurality of baggage items on the placement unit are parallel to one another. Effect of the Invention

[0022] The device for loading luggage onto a cage cart of the present invention can efficiently load the number of luggage that can be loaded onto the cage cart. By improving the loading efficiency, the luggage delivery capacity can be improved and the delivery cost can be reduced.

[0023] In addition, since the gaps can be reduced when loading luggage onto the cart, it is possible to prevent luggage from falling over during transportation. This prevents damage to luggage and the need to replace it. It also eliminates the extra work of wrapping the entire luggage in film to prevent it from falling over due to the gaps.

[0024] In addition, by being able to load an optimized number of items according to the shape and size of the basket cart, total costs and environmental impact can be reduced. [Brief description of the drawings]

[Figure 10] It is a schematic diagram showing the process of loading luggage onto a basket carriage by a luggage loading device in an embodiment of the present invention.

Embodiments for Carrying Out the Invention

[0026] The luggage loading device onto a basket carriage according to the first invention of the present invention includes a placement part having a first placement table, a second placement table connected to one side of the first placement table, and a third placement table connected to the other side of the first placement table, a movement control part that controls the vertical movement of the first placement table, the left-right movement of the second placement table, and the left-right movement of the third placement table, and a loading control part that controls an operation of inserting the placement part into a basket carriage or pulling it out from the basket carriage. The first placement table can place luggage and is vertically movable, The second placement table can place luggage and is horizontally movable, The third placement table can place luggage and is horizontally movable, When the total width of a plurality of pieces of luggage placed on the placement part is larger than the width of the basket carriage (hereinafter referred to as "width-exceeding state"), the movement control unit moves the first placement table upward and moves the second placement table and the third placement table toward the first placement table to make the plurality of loads form a pile; The loading control unit inserts the placement unit into the car dolly while the plurality of baggage items on the placement unit are arranged in a pile, When the overall width of the plurality of luggage placed on the loading section is equal to or less than the width of the car cart (hereinafter referred to as the "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 cart while the plurality of baggage items on the placement unit are parallel to one another.

[0027] This structure allows cargo to be loaded across the entire width of the cart without gaps, preventing gaps from forming and causing cargo to collapse during transportation, and reducing the workload of manually packing cargo.

[0028] In a loading device for a car truck according to a second aspect of the present invention, in addition to the features of the first aspect, in the width exceeding state, the movement control unit: Lifting the first platform on which the baggage is placed, moving the second and third platforms, on which the baggage is placed, closer to the first platform; The overall width of the bottom side of the plurality of pieces of luggage placed on the placement section is equal to or smaller than the width of the car cart.

[0029] This configuration makes it possible to load the cart even if the width is exceeded.

[0030] In a device for loading luggage onto a car dolly according to a third aspect of the present invention, in addition to the first or second aspect of the present invention, luggage is loaded onto the car dolly in the order of a first level, a second level, ..., an Nth level from the bottom surface of the car dolly, The loading section loads a plurality of items corresponding to each of the first to Nth levels, The loading control section loads a plurality of baggage items placed on the placement sections in correspondence with the first to Nth levels, respectively.

[0031] This configuration allows luggage to be efficiently loaded onto the cart by stacking them on top of each other.

[0032] In a device for loading luggage onto a car dolly according to a fourth aspect of the present invention, in addition to the third aspect of the present invention, the first stage to the Nth stage include at least one of the exceeding-width state and the width or less state.

[0033] With this configuration, luggage can be loaded onto the car cart in either the over-width state or the under-width state.

[0034] In the device for loading luggage onto a car dolly according to the fifth aspect of the present invention, in addition to the fourth aspect of the present invention, in the stage in the over-width state among the first stage to the Nth stage, the movement control unit raises the first placement platform on which the luggage is placed, and moves the second placement platform and the third placement platform on which the luggage is placed closer to the first placement platform, so that the luggage placed on the placement platform forms a mountain shape; Among the first stage to the Nth stage, in the stage that is in the state of the width or less, The movement control section makes the first to third placement tables parallel to each other, thereby making the plurality of baggage items placed on the placement section parallel to each other.

[0035] This configuration allows for the loading of luggage suitable for both over-width and under-width conditions.

[0036] In a device for loading luggage onto a car truck according to a sixth aspect of the present invention, in addition to the third aspect of the present invention, the car truck includes a bottom plate and a side frame.

[0037] Thereby, the side frame has a form expanding upward from the bottom plate while ensuring a prescribed minimum opening dimension, and the opening width of the car bogie becomes wider toward the first stage to the Nth stage.

[0038] This configuration allows cargo to be loaded even when the width of the vehicle is exceeded. In particular, automatic loading is possible using a cargo loading device that is a machine, rather than by human labor.

[0039] In a seventh aspect of the present invention, in addition to any one of the third to sixth aspects, the loading control unit The loading sections on which the baggage corresponding to each of the first to Nth levels is placed are inserted into the car cart, After the baggage corresponding to each of the first to Nth levels is loaded onto the car cart, the placement section is pulled out.

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

[0041] In the device for loading luggage onto a car dolly according to an eighth aspect of the present invention, in addition to any one of the third to seventh aspects, the loading control unit In accordance with inserting the placement 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 placement section is controlled so as to press down the plurality of piled up baggage items that are loaded on the over-width stage.

[0042] With this configuration, cargo that is packed in a curved shape can be made parallel (flat).

[0043] In a baggage loading device for a car dolly according to a ninth aspect of the present invention, in addition to any one of the first to eighth aspects of the present invention, in the over-width state, the first loading platform is positioned higher than the positions of the bottom surfaces of the second loading platform and the third loading platform, The bottom surface of the baggage placed on the first platform is located higher than the bottom surfaces of the baggage placed on the second platform and the third platform.

[0044] This configuration allows luggage to be loaded in an arched manner, and luggage 200 can be loaded onto the car truck even if it exceeds the width.

[0045] In a luggage loading device for a cage cart, relating to the 10th invention of the present invention, in addition to any one of the first to ninth inventions, when in a state equal to or less than the width, the bottom surfaces of the first loading platform, the second loading platform and the third loading platform are at approximately the same height.

[0046] With this configuration, if the width is less than the limit, the luggage can be loaded directly into the vehicle, enabling efficient loading.

[0047] In a luggage loading device for a cage cart, related to the 11th invention of the present invention, in addition to any one of the third to tenth inventions, the loading control unit sets the placement section to a height at which luggage is loaded in the first to Nth levels.

[0048] This configuration allows luggage to be loaded in stages.

[0049] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0050] (Embodiment)

[0051] (Analysis by the inventor) The inventor analyzed the occurrence of gaps, which is a problem when loading luggage onto a cart using conventional technology, as follows. Figure 1 is a schematic diagram showing luggage loaded onto a cart using conventional technology, according to the inventor's analysis. The width of the cart and the multiple of the luggage width often do not match (the luggage width is not proportional to the width of the cart). For this reason, when luggage is loaded onto the cart, it does not fit neatly and the last piece cannot be loaded. As shown in Figure 1, a surplus area is generated on the right end.

[0052] If you try to put another piece of luggage into this remaining space, you have to force it in using human or mechanical power, which increases the amount of work required.

[0053] On the other hand, when multiple packages are loaded in a balanced manner, gaps are created between the packages, as shown in Fig. 2. Fig. 2 is a schematic diagram showing the state in which packages are loaded onto a cart in the conventional technology. In both cases shown in Fig. 1 and Fig. 2, the presence of gaps raises concerns that the packages may tip over when the cart carrying the packages is transported by a truck or the like.

[0054] Of course, as mentioned above, there is a problem that the labor and cost increase if another load is inserted and the gap is filled by pushing it in manually or mechanically using a separate machine. Based on such analysis, the inventor has come up with a load loading device that efficiently loads multiple loads to fit the width of the car dolly.

[0055] (Embodiment)

[0056] (Luggage loading flow)

[0057] First, the flow of loading luggage onto a car cart using a luggage loading device for a car cart of the present invention (hereinafter, referred to as "luggage loading device" as necessary) will be described with reference to Figures 3 to 6. First, the loading flow (loaded state) will be described to facilitate understanding of the characteristics of luggage loading by the luggage loading device of the present invention.

[0058] (Loading the first load of luggage) Fig. 3 is a schematic diagram showing a state in which luggage is loaded on the first level onto a car cart in an embodiment of the present invention. Fig. 3 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. 4 to 6. In Fig. 3, luggage 200 is loaded on the first level, which is the lowest level of the car cart 100.

[0059] At this time, multiple pieces of luggage 200 are loaded in a lined-up state in the width direction of the car dolly 100 (the horizontal direction when viewed from the front in FIG. 3). The overall width of the multiple pieces of luggage 200 in the first tier may be greater than the width of the area of ​​the car dolly 100 corresponding to the first tier (hereinafter referred to as an "over-width state"). FIG. 3 shows this state.

[0060] This over-width state is a state in which the overall width of the baggage 200 is such that the line of baggage 200 can be forcibly crammed together by human strength, or a state in which the overall width of the baggage 200 slightly exceeds this.

[0061] In this over-width state, the luggage loading device inserts multiple luggage 200 into the car dolly 100 in a curved shape as shown in Fig. 3. The luggage 200 in the middle is positioned higher than the luggage 200 on both sides. Due to this positional relationship, the overall width of the bottom side becomes smaller than it should be, making it possible to insert the luggage into the car dolly 100.

[0062] Here, the car truck 100 comprises a bottom plate 102 and a side frame 101. The side frame 101 has a shape that spreads out upward from the bottom plate 102. This is shown in the state seen from the front in Fig. 3. Since the side frames 101 on both sides spread out upward, the width increases from the first level to the second level, the third level, and so on upward.

[0063] First, the luggage loading device loads a plurality of luggage 200 in the first stage. If the luggage exceeds the width limit, the luggage 200 in the first stage is loaded in a curved state so as to fit within the width of the car cart 100, with the central luggage 200 being raised as shown in FIG. 3 .

[0064] (1st to 2nd paragraphs) Following Fig. 3, Fig. 4 is a schematic diagram showing the state after the first level of luggage has been loaded onto the car cart. The luggage loading device lifts the central luggage 200 up, and the luggage 200 on both sides are lower than that, and the luggage is loaded onto the car cart 100.

[0065] Next, the state shown in Fig. 5 is reached. Fig. 5 is a schematic diagram showing a state in which the second tier of luggage is loaded onto the car cart in the embodiment of the present invention. The luggage loading device loads the second tier of luggage 200 on top of the first tier of luggage 200. As will be described later, the luggage loading device includes a loading section 2 on which a plurality of luggage 200 is placed for each tier. From a state in which the first tier of luggage 200 is loaded onto the car cart 100 as shown on the left side of Fig. 5, the luggage 200 placed on the loading section 2 is loaded into the second tier position as shown on the right side of Fig. 5.

[0066] As shown on the right side of Fig. 5, when the second layer of luggage 200 is stacked, the placement unit 2 presses down on the first layer of luggage 200 from above. This pressing down and the weight of the second layer of luggage 200 flattens the arched first layer of luggage 200 as shown on the right side of Fig. 5. In this way, the placement unit 2 presses down on the arched luggage from above to flatten it, allowing the next layer of luggage 200 to be stacked on top of it.

[0067] In addition, when the overall width of the second tier of luggage 200 is less than the width of the car cart 100 (hereinafter referred to as the "width or less state"), the second tier of luggage 200 is loaded into the second tier position of the car cart 100 while remaining in a parallel state.

[0068] As a result, the curved first layer of luggage 200 is pressed down and flattened, and the second layer of luggage 200 is loaded in a flat state. As shown on the right side of Fig. 5, the luggage 200 is flattened in both the first and second layers. In this way, the luggage 200 is loaded in a parallel and flat state from the bottom plate 102 to the upper layer.

[0069] Of course, if the second tier also exceeds the width limit, the second tier will also be loaded in a curved state, just like the first tier. When the third tier of luggage 200 above the second tier is loaded, it is pressed down from above by the loading section and the second tier of luggage 200 will also be flattened.

[0070] (From the second stage onwards) Fig. 6 is a schematic diagram showing loading of luggage from the second to fourth tiers in an embodiment of the present invention. The side frame 101 of the car dolly 100 is in a form that widens upward. Therefore, as it goes up to the second tier, the third tier, the fourth tier, through the Nth tier, the width of the car dolly 100 at that height becomes wider. Therefore, when it goes to the upper tier, the luggage loading device can load luggage 200 in a flat state. In this way, luggage 200 can be loaded toward the upper tier as shown in Fig. 6.

[0071] In FIG. 6, the overall width of the luggage 200 in the upper tier is larger, but this is not necessary, and the overall widths of the luggage 200 loaded in the first tier to the Nth tier may be the same.

[0072] As described with reference to Figs. 3 to 6, in the luggage loading device of the present invention, luggage 200 is loaded from the first stage to the Nth stage of the bottom plate 102. At this time, if the luggage exceeds the width, the luggage 200 in the center is raised higher than the luggage on both sides to narrow the width of the bottom side and loaded. The luggage 200 in the arched stage is pressed down and made flat when the luggage 200 in the next stage is loaded. By loading luggage in this flow, even when the luggage 200 is loaded onto the car dolly 100 that exceeds the width, work such as adjusting and pressing it down by hand is not required, and the luggage loading device, which is a machine, can load the luggage.

[0073] (Overview)

[0074] An overall outline of the luggage loading device will be described.

[0075] 7 is a schematic diagram of a luggage loading device for a car cart in an embodiment of the present invention. The luggage loading device 1 places luggage 200 on the car cart 100, and loads the luggage 200 onto the car cart 100 by inserting the luggage loading device 1 into the car cart 100. The luggage loading device 1 also performs an operation of extracting the placement section 2 from the car cart 100, so that after loading the luggage 200, the device can move to load the next luggage 200.

[0076] The luggage loading device 1 includes a placement unit 2, a movement control unit 3, and a loading control unit 4. The placement unit 2 places a row of luggage 200 corresponding to the first to Nth stages of the basket cart 100 described in FIG. 3 and the like. A plurality of luggage 200 are placed along the width direction of the placement unit 2, and the plurality of luggage 200 in the placed row state are loaded onto the first stage, the second stage to the Nth stage of the basket cart 100.

[0077] The placement unit 2 includes a central first placement table 21, second placement tables 22 provided on both sides of the first placement table 21, and third placement tables 23. The first placement table 21 and the second placement tables 22 are connected, and the first placement table 21 and the third placement tables 23 are also connected. Luggage 200 is placed on each of the first placement table 21, the second placement tables 22, and the third placement tables 33, and a plurality of luggage 200 are placed on the entire placement unit 2 by these.

[0078] Also, the placement unit 2 is inserted into the basket cart 100 and luggage is loaded into the basket cart 100. The placement unit 2 corresponds to the width of the basket cart 100, and by lowering the luggage 200 placed on the placement unit 2 inserted into the basket cart 100, the luggage 200 is loaded into the basket cart 100. By repeating the insertion and extraction of the placement unit 2, the loading of the luggage 200 onto the first to Nth stages proceeds.

[0079] That is, the total width of the plurality of luggage 200 placed on the placement unit 2 is in a state where it exceeds the width or is less than or equal to the width when compared with the width of the basket cart 100.

[0080] The placement unit 2 includes the first placement table 21 to the third placement table 23. Here, as shown in FIG. 8, each of the first placement table 21 to the third placement table 23 is movable. FIG. 8 is a schematic diagram showing the function of the placement unit in the embodiment of the present invention.

[0081] The first placement table 21 can place luggage 200 and can move up and down. A vertical drive unit 31 that enables the first placement table 21 to move up and down is provided in the placement unit 2. The movement control unit 3 can move the first placement table 21 up and down by operating the vertical drive unit 31.

[0082] 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.

[0083] The third platform 23 is capable of placing the luggage 200 thereon and of moving left and right. The platform 2 is provided with a left and right drive unit 33 that enables the third platform 23 to move left and right. The movement control unit 3 operates the left and right drive unit 33 to move the third platform 23 left and right.

[0084] When the first platform 21 moves upward with the luggage 200 placed thereon, 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 that only the luggage 200 placed on the first platform 21 moves upward.

[0085] 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 multiple baggage items 200 placed on the first platform 21 to the third platform 23 are arranged in an arched shape as shown in FIG.

[0086] FIG. 9 is a schematic diagram showing that the cargo 200 is curved as a result of the movement of the first to third platforms 21 to 23. As shown in FIG.

[0087] In an over-width state where the overall width of the multiple luggage items 200 placed on the placement section 2 exceeds the width of the car cart 100 at the stage to be inserted, the luggage items 200 cannot be loaded onto the car cart 100 in the state shown on the left in Fig. 9 (where the multiple luggage items 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. 9. In other words, the overall width of the bottom of the luggage items 200 is reduced, making it possible to insert the luggage items 200 in accordance with the width of the car cart 100. The luggage items 200 are arched as shown on the right in Fig. 9.

[0088] 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 the insertion, the luggage 200 is unloaded 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 luggage 200 has been unloaded, i.e., returns it.

[0089] The loading control unit 4 controls loading and unloading of the placement unit 2 onto and from the car dolly 100. As shown in Fig. 6, the luggage loading device 1 loads luggage 200 in a first tier, second tier, third tier, etc. upward from the bottom plate 102 of the car dolly 100. The loading control unit 4 accordingly moves the placement unit 2 to the first tier, second tier, third tier, etc. position.

[0090] To summarize the above, the following can be said:

[0091] A plurality of luggage 200 corresponding to the first tier are 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 constituting 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 luggage 200 (which may be measured based on the width of the placement section 2) with the width of the tier on the car trolley 100 on which the luggage 200 is loaded (determined by a measuring device such as a sensor, or a pre-programmed numerical value).

[0092] If the result of this comparison indicates that the load is over the width, 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. That is, the baggage 200 corresponding to the first tier forms a curve on the platform 2.

[0093] This arching reduces the width of the bottom of the luggage 200, so that even if the luggage 200 exceeds the width limit, it can be inserted into the first stage of the car trolley 100. In this insertable state, the loading control unit 4 inserts the placement unit 2 into the first stage. That is, the placement unit 2 is inserted in an arched state. The inserted placement unit 2 places the luggage 200 in the first stage. The loading control unit 4 can then unload and load the luggage 200 by, for example, tilting the placement unit 2.

[0094] When the loading control unit 4 has finished loading the luggage 200 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 luggage 200 corresponding to the next level. The placement unit 2 also presses down on the arched luggage 200 from above, flattening the arrangement of the luggage 200. The luggage 200 is dropped down to eliminate any floating parts and make the luggage 200 flat.

[0095] In addition, the loading control unit 4 also preferably performs centering so that the centers of the multiple pieces of luggage 200 placed on the placement unit 2 are aligned with the center of the car cart 100. This allows the luggage to be loaded appropriately aligned in the width direction of the car cart 100.

[0096] The placement unit 2 places the baggage 200 corresponding to the second stage. At this time, the overall width of the baggage 200 is compared with the width of the car cart 100 at the second stage to determine whether the baggage 200 is in an over-width state or an under-width state. If the baggage 200 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, in the same manner as in the first stage.

[0097] The placement unit 2 may be provided with a separate mechanism for placing the luggage 200 thereon, and this mechanism may place the luggage 200 on the placement unit 2. For example, a conveyor mechanism may correspond to this, or a mechanism for transferring the luggage 200 from the conveyor mechanism to the placement unit 2 may correspond to this.

[0098] Conversely, if the width is less than the limit, the movement control unit 3 keeps the first placement platform 21, the second placement platform 22, and the third placement platform 23 in a parallel state, and causes the placed baggage 200 to be in a parallel state (left side in FIG. 9). In this state, the loading control unit 4 inserts the placement platform 2 into the second stage position of the car dolly 100. After the insertion, the baggage 200 is removed from the placement platform 2.

[0099] At this time, the second tier of luggage 200 is placed on top of the first tier of luggage 200. The first tier of luggage 200 is arched. The loading control unit 4 operates the placement unit 2 to press down on the first tier of luggage 200 from above. Pressure is applied. This is because when the luggage 200 is loaded in the second tier, the placement unit 2 is on top of the first tier of luggage 200.

[0100] This pressing force brings the first layer of luggage 200, which had been arched, closer to a parallel state. With the weight of the second layer of luggage 200 also added, they also become parallel. As shown in Figures 5 and 6, the same thing that would be done by pushing and packing the luggage by hand is done by the machine.

[0101] The same applies to the third tier and onwards. As a result, it is possible to load luggage 200 in multiple tiers as shown in Figure 6. This makes it possible to prevent gaps from being created as in the conventional technology. In addition, it is possible to reduce the burden of having to cramming luggage tightly by manually pressing it down to prevent gaps from being created.

[0102] On the car dolly 100, the first, second, third,... Nth tiers are stacked from the bottom plate 102 upwards. In any of the 1st to Nth tiers, in the tiers that exceed the width, the luggage 200 placed on the placement section 2 is arched as described above. In the tiers that are equal to or smaller than the width, the luggage 200 placed on the placement section 2 remains parallel. This allows luggage to be loaded in a way that is appropriate for each tier.

[0103] 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 luggage 200 on the placement unit 2 is arched, and in the under-width state, the luggage 200 on the placement unit 2 is parallel.

[0104] (Loading by the luggage loading device) FIG. 10 is a schematic diagram showing the process of loading luggage onto the cage cart by the luggage loading device according to an embodiment of the present invention. By performing the operations described above, the luggage loading device 1 loads the first to Nth stages and the luggage 200 onto the cage cart 100.

[0105] As shown in FIG. 10, the luggage 200 is loaded in the order of 1 to 11. In the first stage, the overall width of the luggage 200 is in a state of exceeding the width. In this case, on the placement part 2, the first placement table 21 moves upward, and the second placement table 22 and the third placement table 23 approach the first placement table 21. As a result, the luggage 200 in the first stage becomes mountain-shaped as shown in 1 of FIG. 10.

[0106] Also in the second stage, since it is in a state of exceeding the width, the luggage 200 is also loaded in a mountain-shaped state. In the third stage, since it is in a state of being equal to or less than the width, the luggage 200 is loaded in a parallel state.

[0107] In the state of exceeding the width, the position of the bottom surface of the first placement table 21 is higher than the positions of the bottom surfaces of the second placement table 22 and the third placement table 23. By placing the luggage in such a manner, the luggage 200 becomes mountain-shaped. This is because the bottom surface of the luggage 200 placed on the first placement table 21 is higher than the positions of the bottom surfaces of the luggage 200 placed on the second placement table 22 and the third placement table 23.

[0108] In the state of being equal to or less than the width, the bottom surfaces of the first placement table 21, the second placement table 22, and the third placement table 23 are at substantially the same height. Due to this substantially the same height, the placed luggage 200 is in a parallel state. The movement control unit 3 controls the placement part 2 in this way so that the luggage 200 can be loaded according to the stage. Also, the loading control unit 4 adjusts the height of the placement part 2 to the height of the stage to be loaded. In this way, the first to third stages and the luggage 200 are loaded.

[0109] In Fig. 10, after the first tier of luggage 200 has been loaded, the luggage 200 that was curved becomes parallel. Before the luggage 200 on the upper tier is loaded, the placement unit 2 presses down the curved luggage 200 to make it parallel. Alternatively, as described with reference to Figs. 3 to 6, when the luggage 200 on the tier above the curved luggage 200 is loaded, the luggage 200 may be pressed down by the placement unit 2 to make it parallel.

[0110] In this way, in the process of loading the luggage 200 in the order of the first to third tiers, luggage 200 is loaded in correspondence with the tiers in the over-width state and the tiers in the width or less state, respectively. This allows the final required number of tiers of luggage 200 to be loaded onto the car cart 100. In addition, the tiers in the over-width state can also be loaded tightly in the width direction, so that the luggage is loaded without any gaps.

[0111] This can prevent problems such as luggage falling during transportation.

[0112] Loading onto the car cart 100 as shown in FIG.

[0113] The loading control unit 4 executes this by loading the placement units 2, on which luggage corresponding to each of the first to Nth levels is placed, onto the car cart 100. At this time, with the luggage 200 placed on the placement units 2, the loading control unit 4 inserts the placement units 2 on which the luggage 200 is placed into the car cart 100. As a result, the luggage 200 is loaded onto the car cart 100. Thereafter, the loading control unit 4 pulls out the placement units 2 from the car cart 100.

[0114] The loading control unit 4 also controls the placement unit 2 to press down on the arched cargo 200. By pressing down, the arched cargo 200 can be made parallel.

[0115] As described above, the baggage loading device 1 of the present invention can prevent gaps from being generated between adjacent baggage 200 on the car dolly 100. In addition, in order to prevent gaps from being generated, the workload of manually pushing the baggage tightly can be reduced.

[0116] In addition, if necessary, it is also preferable to provide a loading mechanism for loading the cargo 200 on the loading section 2 and a control section related thereto. For example, a conveyor connected to the loading section 2 may be provided, and the conveyor may move the corresponding cargo 200 one level at a time and load it onto the loading section 2.

[0117] At this time, the movement of the first platform 21, the second platform 22, and the third platform 23 by the movement control unit 3 may be performed after the luggage 200 is placed on the platform. By performing the movement after the luggage 200 is placed on the platform, the luggage 200 corresponding to one tier can be placed together by the conveyor.

[0118] As mentioned above, it is also preferable to provide a sensor for adjusting the height of the placement unit 2 to the height of the first to Nth stages, and a sensor for detecting whether the width is exceeded or not. These sensors may be optical sensors.

[0119] In addition, a mechanism may be provided for sending the car car 100 out for delivery after loading onto the car car 100 is completed. A mechanism for setting an empty car car 100 may also be provided.

[0120] The device for loading luggage onto a car truck described in the embodiment is merely an example for explaining the gist of the present invention, and includes modifications and alterations that do not depart from the gist of the present invention. [Explanation of symbols]
