Description

TECHNICAL FIELD The present invention relates to a cargo loading device for a car carriage, which loads a cargo in which articles are boxed into a car carriage in a state of good loading efficiency.

BACKGROUND ART Many kinds of articles are manufactured with the diversification of people's tastes. A wide variety of these articles are manufactured by various manufacturers. They are manufactured by manufacturers in various regions, whether in Japan or overseas. This requires many items to be delivered from various regions to other regions.

Such articles are distributed from manufacturers to retailers, wholesalers, and the like. Alternatively, it may be picked up by a carrier and the carrier may combine and deliver various items.

Internet shopping is also booming. Customers have changed from the conventional style of directly visiting retail stores (supermarkets and department stores) to purchase products and take them home with them, while ordering products on the Internet and making electronic payments. Even in such Internet shopping, it is necessary to deliver the ordered and settled merchandise to the purchaser.

In such cases, various goods are also delivered to the purchaser from manufacturers, distributors, and the like. Alternatively, it is picked up and delivered by a delivery company. Articles are often delivered in a box such as a cardboard box. This is for the purpose of managing delivery destinations and delivery amounts while preventing damage to items during delivery.

Of course, there are many occasions when it is necessary to load a truck with a large number of boxes filled with the same type of goods. There are many cases in which a plurality of cardboard boxes packed with the same product are loaded on a trolley.

Actors with various roles such as manufacturers, distributors, and distributors deliver goods to required locations.

As described above, goods are often housed in a box such as a cardboard box and delivered instead of being delivered as they are. That is, the article is delivered as a package in a box. Delivery management is performed by attaching a bar code or a two-dimensional bar code to the box.

Here, goods packed in boxes are loaded on trucks, freight trains, ships, or the like and delivered. At this time, in order to improve work efficiency, the boxed packages are loaded onto a truck or the like while being loaded on a cage truck or the like. This is because the delivery efficiency is improved by loading a large number of packages together on a truck or the like.

Of course, by loading a plurality of loads on a cart or the like, the work burden and physical burden on the worker are reduced. It also has the advantage of increasing the efficiency of unloading after delivery. For example, by collectively loading a plurality of packages for the same delivery destination on a cart, delivery efficiency and work efficiency can be improved. This is because it is only necessary to hand over the car carriage transported by a truck or the like to a certain delivery destination.

In this way, loading for efficient delivery of packages containing a wide variety of articles is required. Techniques related to this have been proposed (see Patent Documents 1 and 2, for example).

JP 2015-37992 A

Patent Document 1 discloses a product case conveying step of picking up a corresponding product case 12 based on shipping instruction information and conveying it by a belt conveyor (conveying means) 14, recognizing characteristic information of the product case 12, A product case sorting step for sorting and conveying to the storage transport means 20 corresponding to the characteristic information, and a cart truck 22 used for stacking the product cases 12 and transporting them to the shipping destination to the product case 12 loading area 26 , shipping instruction information, characteristic information of the product case 12, and the placement state of the product case 12, and stowage data is created from the shipping instruction information. An automatic stowage system is disclosed that includes a product case stow step for stacking and in sequence, and a car truck unloading step for unloading each car truck 22 from the stowage area 26 .

However, in order to load products onto the carriage by the automatic mechanism, it is necessary to create a distance between the commodities loaded on the carriage in order to secure the operating area required for the operation of this mechanism. . Alternatively, the loading of the automatic mechanism will inevitably result in a distance between the products.

In addition, there is no proportional relationship between the width of the carriage and the width of the products, and there is a possibility that gaps will inevitably occur when a plurality of commodities are stacked in the lateral direction of the carriage.

In this way, if there is a distance between the packages loaded on the carriage, there is a problem that the packages fall down while being transported by a truck or the like. If the luggage falls over, it is natural that problems such as damage to the stored products and articles may occur.

In order to prevent overturning, it is necessary to fix the load by wrapping the cart with film while the load is loaded. This leads to problems such as cost, labor, and labor for unloading after delivery.

As described above, conventional technologies such as Patent Document 1 disclose techniques for automatically loading packages onto a trolley. (3) The loading efficiency of the cargo on the truck is lowered, and (4) Measures to prevent overturning are time-consuming and costly.

In addition, at actual work sites, a line of cargo that cannot be accommodated by a machine has to be forcibly pushed in by hand. . Naturally, all of the placement, loading, and proper loading is done manually, and there is also the problem that it is impossible to place and load by machine in the first place.

In addition, at actual worksites, a skilled worker can load a line of cargo that cannot be accommodated by a machine. It was possible to work to match the Naturally, all of the placement, loading, and proper loading is done manually, and there is also the problem that it is impossible to place and load by machine in the first place.

In addition, it is difficult to load a large amount of cargo when it comes to manually loading the cargo onto the cart. This is because there are problems such as labor and time. As mentioned above, it is necessary to load a large number of packages one after another onto the car truck. In this case, it is difficult to do it manually. In addition, loading with gaps also causes problems such as load collapse during transportation. Alternatively, it is necessary to load by a mixture of machine and human power, which is also not realistic.

In other words, in addition to the above-described problems, the conventional technology has a problem that a large amount of cargo cannot be efficiently loaded on the car truck.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Analysis by inventor)
The inventor analyzed the generation of gaps, which is a problem in loading cargo on a truck in the prior art, as follows. FIG. 1 is a schematic diagram showing a loading state of cargoes on a car bogie according to the inventor's analysis in the prior art. In many cases, the width of the carriage does not match the overall width of the packages (the width of the packages is not proportional to the width of the carriage). For this reason, when loads are loaded onto the car carriage, the last one cannot be loaded because they do not fit neatly. As shown in FIG. 1, a surplus area is generated at the right end.

If another package is to be put into this surplus area, it is necessary to forcibly push it in using human power or a machine. In this case, there is a problem that the labor of the work increases.

On the other hand, if a plurality of packages are loaded with a margin of width, gaps will occur between the packages as shown in FIG. FIG. 2 is a schematic diagram showing how cargo is loaded onto a car bogie in the prior art. In both cases of FIGS. 1 and 2, there is a concern that the cargo may overturn when the car carriage loaded with the cargo is transported by a truck or the like due to the presence of the gap.

Of course, as described above, there is the problem of increased labor and cost if another package is put in and the gap is eliminated manually or by mechanical work using a separate machine. Based on such an analysis, the inventor has arrived at a cargo loading device that efficiently loads a plurality of cargoes so as to match the width of the cage truck.

In particular, although it is not impossible to manually push in tightly, there is a problem that the work burden on the operator increases. Of course, extra human resources are required for loading, and automation of loading becomes difficult. In addition, there also arises a problem of prolongation of working time due to manual work.

(Embodiment 1)

(overall overview)
FIG. 4 is a block diagram of the cargo loading device according to Embodiment 1 of the present invention. The entire cargo loading device 1 is shown as viewed from above. In addition, FIG. 4 also shows an operator 500 who moves and operates a car truck loaded with cargo in the cargo loading apparatus 1 .

The cargo loading device 1 loads cargoes 200 on the first stage, the second stage, . . . As shown in FIG. 5, the cargo 200 on the first stage is loaded from the bottom plate of the car carriage 100, the next cargo 200 is loaded on the second stage above the first stage, and the cargo 200 is loaded up to the Nth stage. . At this time, as shown in FIG. 5, the loads 200 loaded on the first to Nth stages are in a state in which a plurality of loads 200 are arranged side by side.

FIG. 5 is a front view showing a state in which cargo is loaded on the cage bogie according to Embodiment 1 of the present invention. They are loaded in order from the 1st stage to the Nth stage. The cargo 200 corresponding to each of the 1st, 2nd, . . . Nth tiers will be referred to as "loading stage cargo" as required.

The cargo loading device 1 includes a take-out mechanism 30 , a transfer mechanism 40 and a loading mechanism 20 .

The take-out mechanism 30 takes out the packages 200 corresponding to the 1st, 2nd, . . . In the baggage storage area 220, a large number of boxes 200, such as cardboard boxes, are stored. Also, new packages 200 may be brought into the package storage area 220 one after another.

The take-out mechanism 30 takes out the loaded cargo from the cargo storage area 220 . This is handed over to the transfer mechanism 40, and finally the loading stage cargo is loaded on the car carriage 100. - 特許庁

In other words, the cargo loading device 1 has a function of moving and loading the cargo 200 from the cargo accommodation area 220 to the car carriage 100 .

The transport mechanism 40 transports the load-level cargo taken out by the take-out mechanism 30 to the loading mechanism 20 . Since it is transferred as a loading stage cargo, the unit to be transported is a loading stage cargo. By transferring the cargo in units of loading stages, the loading mechanism 20 can load the cargo on the car truck 100 in the state of the loading stages.

FIG. 6 is a perspective view showing the operation of the transfer mechanism according to Embodiment 1 of the present invention. The transport mechanism 40 transports the stack 210 as shown in FIG. The number of loads 200 included in the load stage load 210 is determined by comparing the widths of the car carriage 100 and the load 200 . The take-out mechanism 30 collectively takes out the articles 200 corresponding to the determined number, and delivers them to the transfer mechanism 40 in the state of the loaded stage articles 210 .

The transfer mechanism 40 hands over the loading staged cargo 210 to the loading mechanism 20 . By being handed over, the loading mechanism 20 can load the cargo 200 on the car carriage 100 in the state of the loading stage cargo 210 .

The loading mechanism 20 loads the cargo 210 in the state corresponding to the first stage, the second stage, . . . As shown in FIG. 5 , the loading mechanism 20 sequentially loads the articles 200 onto the car truck 100 .

The car truck 100 loaded with the cargo 200 by the loading mechanism 20 is moved to the next stage by the operator 500 . Also, the operator 500 installs a new empty car truck 100 .

In this way, the cargo loading device 1 can cover the entire area from the cargo accommodation area 220 to the unloading of the car carriage 100 in the loaded state.

(Baggage Loading Flow by Loading Mechanism 20)

7 to 9, the flow of loading cargo onto the car truck by the loading mechanism 20 will be described. First, the loading flow (state of being loaded) will be described. As described with reference to FIGS. 1 and 2, the cargo loading device 1 may cause the width of the loading stage cargo 210 to exceed the width of the car carriage 100 (“exceeding width state”). Even if there is such a premise, it can be loaded so as to fit properly in the car truck 100. - 特許庁

(Loading of cargo on the first stage)
FIG. 7 is a schematic diagram showing a state in which the first-stage cargo is loaded onto the car bogie in the embodiment of the present invention. FIG. 7 shows the car truck 100 viewed from the front (the side where the cargo 200 is opened). 8 and 9 are the same. In FIG. 7 , a loading stage cargo 210 including a plurality of cargos 200 is loaded on the first stage, which is the lowest stage of the car carriage 100 .

At this time, a plurality of packages 200 are stacked in a state of being lined up in the width direction of the car carriage 100 (horizontal direction as viewed from the front in FIG. 7) (state of loading stage packages 210). There is a case where the overall width of the first-tier loaded-tier cargo 210 is greater than the width of the area corresponding to the first tier of the car carriage 100 (hereinafter referred to as "over-width condition"). FIG. 7 shows this state.

In such a state of exceeding the width, the loading mechanism 20 inserts a plurality of packages 200 into the car carriage 100 in a pile as shown in FIG. The luggage 200 in the middle is positioned above the luggage 200 on both sides. Due to this positional relationship, the overall width of the bottom portion side becomes smaller than it should be, so that it can be inserted into the car bogie 100 .

Here, the car bogie 100 includes a bottom plate 102 and side frames 101 . The side frame 101 has a shape that spreads upward from the bottom plate 102 . The state seen from the front in FIG. 7 shows this. Since the side frames 101 on both sides widen upward, the width increases from the first step upward to the second step, third step, and so on.

First, the loading mechanism 20 loads the loading level cargo 210 on the first level. In the overwidth condition, as shown in FIG. 7, the first-level cargo 200 is loaded so as to fit within the width of the car carriage 100 in a mountain-like positional relationship with the center cargo 200 raised upward.

(First stage to second stage)
Following FIG. 7, it becomes like FIG. FIG. 8 is a schematic diagram showing loading of cargo from the first stage to the second stage. By the loading mechanism 20, as shown on the left side of FIG. 8, the cargo 200 in the center is lifted and the cargoes 200 on both sides are loaded on the cart 100 in a state below it.

Then, the state shown on the right side of FIG. 8 is reached. The loading mechanism 20 loads the second loading level cargo 210 on top of the first loading level cargo 210 . As will be described later, the stacking mechanism 20 includes a mounting portion on which the stacked cargo 210 is placed for each stage. As shown in the left side of FIG. 8, from the state in which the first-stage cargo 210 is loaded on the car carriage 100, the loaded cargo 210 on the placing portion as shown in the right side of FIG. loaded at the position of

As shown on the right side of FIG. 8 , when the second load level cargo 210 is stacked, the placement section presses the first load level load 210 from above. Due to this pressing and the load of the second loading stage cargo 210, the first loading stage cargo 210, which had been formed into a mountain, is flattened as shown on the right side of FIG.

In addition, when the overall width of the second-stage loading stage 210 is equal to or less than the width of the car carriage 100 (hereinafter referred to as "width or less state"), the second-stage loading stage 210 is in a parallel state. It is loaded into the position of the second stage of the car bogie 100 as it is.

As a result, the piled first-stage cargo 210 is pressed down and flattened, and the second-stage cargo 210 is loaded in a flat state. As shown on the right side of FIG. 8, the load tiers 210 are flattened at each of the first and second tiers. In this way, the loaded stage cargo 210 is stacked in a parallel and flat state from the bottom plate 102 toward the upper stage.

Of course, if the second stage is also in the over-width state, the loading stage cargo 210 in the second stage is also loaded in the same pile state as in the first stage. When the third loading stage 210 above the second stage is stacked, the loading section 210 presses down from above and the second loading stage 210 also becomes flat.

(Second stage and beyond)
FIG. 9 is a schematic diagram showing loading of cargo from the second stage to the fourth stage in Embodiment 1 of the present invention. The side frame 101 of the car bogie 100 is in a form that spreads upward. For this reason, the width of the car truck 100 at each height increases as it goes up to the 2nd, 3rd, 4th, . . . Nth stages. For this reason, when going to the upper stage, the loading mechanism 20 can load the loading stage cargo 210 in a flat state. In this way, as shown in FIG. 9, the loaded stage cargo 210 can be loaded toward the upper stage.

In FIG. 9, the entire width of the loading stage 210 on the upper stage is large, but this is not necessarily the case. may be the same.

As described with reference to FIGS. 7 to 9, in the cargo loading device 1 of the present invention, the loading stage cargo 210 is loaded from the first stage to the Nth stage of the bottom plate 102 . At this time, in the over-width state, the central cargo 200 is raised above the cargo on both sides to narrow the width of the bottom surface side and loaded. The cargo 200 on the mountain-like tier is flattened by being pressed down when the cargo 210 on the next tier is stacked. By loading in this flow, even when loading the load stage cargo 210 onto the car carriage 100 that exceeds the width, it is possible to load by a mechanical cargo loading device, eliminating the need for manual adjustment and pressing work. It becomes possible.

By repeating the insertion and withdrawal of the placing section 2, the loading of the loaded stage cargo 210 on the 1st to Nth stages proceeds.

In other words, the overall width of the plurality of packages 200 placed on the placement section 2 is in a state of exceeding or less than the width of the car carriage 100 .

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 (moving operation refers to vertical movement and horizontal movement). 11A and 11B are schematic diagrams showing the functions of the placing section according to the embodiment of the present invention.

The first mounting table 21 can mount the load 200 and can move up and down. The mounting section 2 is provided with a vertical driving section 31 that enables the vertical movement of the first mounting table 21 . The movement control unit 3 can vertically move the first mounting table 21 by operating the vertical driving unit 31 .

The second mounting table 22 can mount the load 200 and can move left and right. The mounting unit 2 is provided with a left-right driving unit 32 that enables the left-right movement of the second mounting table 22 . The movement control unit 3 can move the second mounting table 22 left and right by operating the left and right drive unit 32 .

The third mounting table 23 can mount the load 200 and can move left and right. The mounting unit 2 is provided with a left-right driving unit 33 that allows the third mounting table 23 to move left and right. The movement control unit 3 can move the third mounting table 23 left and right by operating the left and right driving unit 33 .

When the first mounting table 21 moves upward while the load 200 is placed thereon, the load 200 placed on the first mounting table 21 is positioned upward. At this time, since the second mounting table 22 and the third mounting table 23 do not move upward, only the load 200 on the first mounting table 21 is positioned upward.

In addition, the second mounting table 22 moves left and right to approach the first mounting table 21 , and the third mounting table 23 also moves left and right to approach the first mounting table 23 . By doing so, the plurality of packages 200 placed on the first to third placing tables 21 to 23 form mountains as shown in FIG.

FIG. 12 is a schematic diagram showing that the cargo 200 of the loading stage cargo 210 is in a mountainous state due to the moving operation of the first loading table 21 to the third loading table 23. As shown in FIG.

In a state in which the entire width of the plurality of load stages 210 placed on the placement section 2 exceeds the width of the car carriage 100 of the stage to be inserted, the state shown on the left side of FIG. ) cannot be loaded onto the car truck 100. In this over-width state, as shown on the right side of FIG. The width of 2 becomes smaller. That is, the overall width of the bottom portion of the loading stage 210 is reduced, so that it can be inserted in accordance with the width of the car carriage 100 . The load stage 210 is in a mountainous state as shown on the right side of FIG. 12 .

The loading control unit 4 controls insertion of the placement unit 2 into the car carriage 100 or withdrawal from the car 100 . The placing portion 2 on which the luggage 200 is placed is inserted into the car carriage 100 . After the insertion, the loading stage cargo 210 is lowered onto the car carriage 100 from the placement section 2 . The loading control unit 4 pulls out the placing unit 2 on which the loaded staged goods 210 have been unloaded from the car carriage 100 . i.e. return.

The loading control unit 4 controls loading and unloading of the loading unit 2 to and from the cage carriage 100 . Further, as shown in FIG. 9, the cargo loading apparatus 1 loads cargo 210 in the first, second, third, . . . In accordance with this, the loading control section 4 moves the placement section 2 to the positions of the first stage, the second stage, the third stage, and so on.

The above is summarized as follows.

A plurality of packages 200 (loading stage packages 210) corresponding to the first stage are placed on the placing section 2 . At this time, the baggage 200 is placed on each of the first mounting table 21 , the second mounting table 22 and the third mounting table 23 that constitute the mounting section 2 . At least one of the movement control unit 3 and the loading control unit 4 determines the overall width of the loading stage 210 (which may be measured by the width of the loading section 2) and the width of the stage on which the loading stage 210 is loaded in the car carriage 100. are compared (determined from measuring instruments such as sensors, or from pre-programmed numerical values).

As a result of this comparison, if the width is exceeded, the movement control unit 3 moves the first mounting table 21 upward, and directs the second mounting table 22 and the third mounting table 23 toward the first mounting table 21. move. As shown in FIG. That is, the loaded stage cargo 210 corresponding to the first stage forms a mountain on the placing section 2 .

By forming this mountain, the width of the bottom surface of the loading stage cargo 210 becomes small, and even if the loading stage cargo 210 is in an over-width state, it can be inserted into the position of the first stage of the car carriage 100 . In this insertable state, the loading control section 4 inserts the placement section 2 to the position of the first stage. That is, the placing section 2 is inserted in a mountain-like state. The inserted placement section 2 places the loading stage cargo 210 at the first stage position. The loading control unit 4 may tilt the loading unit 2 to unload and load the load 200 .

The loading control unit 4 pulls out (pulls back) the placement unit 2 after loading the loading stages 210 onto the car carriage 100 . As a result, the loading unit 2 can place the stacked cargo 210 corresponding to the next stage.

Next, the placing section 2 places the loading stage cargo 210 corresponding to the second stage. At this time, the overall width of the loaded cargo 210 and the width of the car carriage 100 in the second stage are compared to determine whether it is in an over-width state or a below-width state. If the width is exceeded, the movement control unit 3 moves the first mounting table 21 upward and moves the second mounting table 22 and the third mounting table 23 to the first mounting table as in the case of the first stage. Move to 21.

Conversely, if it is in the width or less state, the movement control unit 3 keeps the first mounting table 21, the second mounting table 22, and the third mounting table 23 in the parallel state, and moves the loaded baggage 210 thereon. Make it parallel (left side of FIG. 12). In this state, the loading control section 4 inserts the placing section 2 into the position of the second stage of the car truck 100 . After the insertion, the load stage cargo 210 is stacked on the second stage position of the cage truck 100 from the placing section 2 .

At this time, the second loading level cargo 210 is on top of the first loading level cargo 210 . The first stage load stage 210 is shaped like a mountain. The loading control unit 4 operates the loading unit 2 to hold down the first loading stage 210 from above. Hold by applying pressure. This is because the loading section 2 is above the cargo 200 on the first stage when the cargo 210 is stacked on the second stage.

As a result of this pressing, the first-stage load stage cargo 210, which has been formed into a mountain, approaches a parallel state. The load of the second loading stage cargo 210 is also added, and the cargo becomes parallel. It is as shown in FIG. 8, FIG. 9, and the like. The same thing as pushing and stuffing by hand is done by machine.

The same applies to the third and subsequent stages. As a result, as shown in FIG. 9, the load stage cargo 210 can be loaded in a plurality of stages. It is possible to prevent the formation of gaps as in the prior art. In addition, it is possible to reduce the burden of manually pressing down to close the gap.

On the car bogie 100, the first stage, the second stage, the third stage, . . . In any one of the first stage to the first stage, in the stage in which the width is exceeded, the loaded stage cargo 210 placed on the placing section 2 is shaped like a mountain as described above. In the under-width stage, the load stage 210 placed on the platform 2 remains parallel. Thereby, the load 200 suitable for each can be loaded.

Stages 1 through N include at least one of an over-width state and a below-width state. In the state of exceeding the width, the stacked articles 210 of the placing section 2 are formed in a mountain shape, and in the state of less than the width, the stacked articles 210 of the placing section 2 are made parallel.

(Loading with Baggage Loading Device)
13A and 13B are schematic diagrams showing the process of loading cargo onto the car truck by the cargo loading device according to Embodiment 1 of the present invention. By performing the operations described above, the cargo loading device 1 loads the cargo 200 from the first stage to the Nth stage onto the car truck 100 .

As shown in FIG. 13, packages 200 are loaded in the order of 1-11. In the first stage, the entire width of the loaded stage cargo 210 is in an over width state. In this case, in the mounting section 2 , the first mounting table 21 moves upward, and the second mounting table 22 and the third mounting table 23 approach the first mounting table 21 . As a result, the first load stage 210 forms a mountain as indicated by 1 in FIG. 13 .

Since the second stage is also in the state of exceeding the width, the loading stage cargo 210 is also stacked in a pile state. In the third stage, since it is below the width, the loading stage cargo 210 is loaded in a parallel state.

In the over-width state, the bottom surface of the first mounting table 21 is positioned higher than the bottom surfaces of the second mounting table 22 and the third mounting table 23 . By placing the cargo in this manner, the loading stage cargo 210 becomes piled up. This is because the bottom surface of the package 200 placed on the first table 21 is higher than the bottom surface of the package 200 placed on the second table 22 and the third table 23 .

In the below-width state, the bottom surfaces of the first mounting table 21, the second mounting table 22, and the third mounting table 23 have substantially the same height. Due to this substantially the same height, the load 200 placed thereon is in a parallel state. The placement section 2 is controlled in this way by the movement control section 3, so that the loaded stage cargo 210 can be loaded in accordance with the stage. Further, the loading control unit 4 adjusts the height of the loading unit 2 to the height of the loading stage. In this way, the first to third stages and the loading stage cargo 210 are loaded.

In FIG. 13 , after the first stack of cargo 210 is loaded, the mountain of cargo 210 becomes parallel. Before stacking the load 210 on the upper stage, the pile of load 200 is pressed down by the placement part 2 to be parallel. Alternatively, as described with reference to FIGS. 7 to 9, when the loading stage cargo 210 on the upper stage of the loading stage cargo 210 forming a mountain is loaded, it is pressed by the loading section 2 to form a mountain. It may be parallel from

In this way, in the process of loading the load tiers 210 in the order of the first to third tiers, the load tiers 210 correspond to the tiers in the over-width state and the tiers in the under-width state, respectively. to load. As a result, the finally required number of stages of the loaded staged goods 210 can be loaded on the car carriage 100 . In addition, since the tiers that exceed the width can be stacked exactly in the width direction, the tiers can be stacked without gaps.

As a result, problems such as the luggage falling during transportation can be prevented.

Loading onto the car truck 100 as shown in FIG. 13 is performed by the loading control unit 4 .

The loading control unit 4 loads the loading units 2 on which the loads corresponding to the first to N-th stages are loaded onto the car carriage 100 . At this time, the loading control unit 4 inserts the loading section 2 on which the loading stage 210 is placed into the car carriage 100 while the loading stage 210 is placed on the loading section 2 . As a result, the loading stage cargo 210 is loaded on the car carriage 100 . After that, the loading control section 4 pulls out the placing section 2 from the cage truck 100 .

In addition, the loading control unit 4 performs control so that the placing unit 2 is pressed down from above the mountain-shaped stacks 210 . By this pressing, the mountain-shaped stack 210 can be made parallel.

As described above, the cargo loading device 1 according to Embodiment 1 can prevent the gap between the adjacent cargoes 200 with respect to the car carriage 100 . In addition, in order to prevent the formation of gaps, it is possible to reduce the work burden of manually pushing in and squeezing.

(Embodiment 2)

Next, Embodiment 2 will be described. In the second embodiment, the details of the take-out mechanism 30 and the moving mechanism 40 will be described.

(Luggage storage area)
As shown in FIG. 4, the luggage storage area 220 accommodates multiple packages 200 . The package 200 is in the form of a cardboard box containing articles. It may be not only a cardboard box but also other forms of boxes.

A large number of packages 200 are stored in the package storage area 220 and taken out by the take-out mechanism 30 . At this time, the unloading mechanism 30 unloads the loaded cargo 210 in accordance with the first stage of loading on the car truck 100, and so on. In other words, if the number of the loaded cargo 210 is five cargoes 200 , the take-out mechanism 30 takes out the five cargoes 200 .

For this reason, in accordance with this, it is preferable that five pieces of baggage 200 are stored in a line in the baggage storage area. Of course, the size of the car carriage 100, the size of the cargo 200, and even if the car carriage 100 is the same, the number of items that can be loaded differs depending on the tiers, such as the 1st tier to the Nth tier. For this reason, it is not necessary to store the number of packages in the package storage area 220 in accordance with the number of stacked packages 210 .

The package storage area 220 may also be connected to a delivery facility through which the next package 200 is delivered. The cargo 200 is supplied by a conveyor or the like, the cargo 200 is supplied manually, or the cargo 200 is supplied by a transportation machine. In this way, the load storage area 220 stores the load 200 required to be loaded onto the car truck 100 .

(Extraction mechanism)
The take-out mechanism 30 takes out the package 200 from the package storage area 220 . The load 200 that has been taken out is carried to the loading mechanism 20 through the transfer mechanism. The retrieving mechanism 30 includes a moving frame plate, a robot arm, or the like, so that the package 200 can be retrieved from the package storage area 220 to the transfer mechanism 40 .

Alternatively, rollers may be provided between the load-receiving area 220 and the transport mechanism to deliver the load 200 to the transport mechanism.

Here, it is preferable for the take-out mechanism 30 to take out from the package storage area 220 the number of packages 200 corresponding to the number of stacked packages 210 . FIG. 6 shows a state in which loads 210 (the number of loads 200 corresponding to the number of loads 200 to be loaded on the loading stages of the car 100) are taken out and transferred by the transfer mechanism 40. FIG.

Since the take-out mechanism 30 takes out the number of packages 200 corresponding to the loading stage packages 210, the efficiency of the work in the transfer mechanism 40 and the stacking mechanism 20 can be improved. This is because the stacking mechanism 20 processes the stacks 210 as one unit.

For this reason, the take-out mechanism 30 may be provided with a sensor for grasping the number of packages 200 and the width corresponding to the stacked packages 210 . Alternatively, it may be programmed in advance and the number of packages 200 corresponding to the number of stack packages 210 may be retrieved according to this programming. Of course, the operator may adjust the number of packages 200 to be taken out by operating an operation switch or the like as necessary.

The take-out mechanism 30 is connected to the transport mechanism 40, and the load 200 that has been taken out is transported by the transport mechanism 40 as it is. FIG. 6 also shows transfer with this transfer mechanism 40 .

(transfer mechanism)
The transfer mechanism 40 transfers the load 200 taken out by the take-out mechanism 30 to the loading mechanism 20, as shown in FIG. The luggage 200 may be transferred by a conveyor mechanism such as a roller conveyor as shown in FIG. 66 or a belt conveyor. Also, the packages 200 corresponding to the number of the loading stage packages 210 may be transferred as one unit.

This is because by transporting this as one unit, the loading mechanism 20 can efficiently load the load 200 transported by the transport mechanism 40 as it is. This is because the loading mechanism 20 can handle the number of packages 200 sent in units.

FIG. 14 is a side view showing the load from the transfer mechanism to the loading mechanism in Embodiment 2 of the present invention.

The transfer mechanism 40 transfers the load 200 and then hands it over to the loading mechanism 20 . Here, the transport mechanism 40 includes transport means 41 for transporting the load 200 corresponding to the loading stage load 210 and placing means 42 for placing the load 200 on the loading section 2 of the loading mechanism 20 . FIG. 14 shows this configuration.

The transport means 41 transports the load 200 . For example, it has a conveyor mechanism to transfer the load 200 to a position corresponding to the placing section 2 . FIG. 6 shows a state in which the load 200 is transferred by the roller conveyor. When transferred to this position, the load 200 is handed over to the loading mechanism 20 .

The placing means 42 places the load 200 arrived by the transfer means 41 on the placing portion 2 of the loading mechanism 20 . In FIG. 14 , a push-out mechanism for pushing out the load 200 onto the placing section 2 is provided, and this serves as the placing means 42 . The transfer directions of the stacking mechanism 20 and the transfer mechanism 40 intersect. Therefore, the placing means 42 such as a pushing mechanism moves the load 200 in a direction intersecting the transfer direction of the transfer means 41 .

FIG. 14 shows movement in this cross direction. A load 200 carried by the transfer means 41 is pushed out in a direction from right to left in FIG. 14 (crossing the direction of transfer by the transfer means 41). By this pushing out, the transported baggage 200 is placed on the placement section 2 .

Further, as shown in FIG. 14 , the placing means 42 may hold a plurality of articles 200 corresponding to the stacked article 210 so as to sandwich them from both sides and move them to the placing section 2 . It is also preferable to adjust the widthwise positions of the plurality of articles 200 corresponding to the stacked articles 210 by sandwiching them from both sides.

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

After being positioned as described above, it is placed on the placement section 2 . Thereby, each of the packages 200 placed on the placing section 2 is placed in an appropriate state. Since it is loaded on the car truck 100 from this state, it is possible to load in an appropriate and neat posture.

The cargo 200 of the load stage cargo 210 whose position has been adjusted is placed on the placing section 2 . As described in the first embodiment, the mounting portion 2 may be shaped like a mountain or made parallel as necessary. With this change in mode, the loading section 2 is inserted into the cage carriage 100 and loaded with the loaded cargo 210 .

(Up and down control of the placing section)
FIG. 15 is a side view for explaining the vertical movement of the placement section with respect to the cage bogie according to the second embodiment of the present invention. It is shown based on the relative relationship between the cage truck 100 and the loading mechanism 20 .

The loading control unit 4 moves the mounting unit 2 up and down to positions corresponding to the first stage, the second stage, . . . FIG. 15 represents this vertical movement. Due to the vertical movement of the loading section 2, the stacking stage cargo 210 is appropriately loaded onto the stage to be loaded.

Further, the placing means 42 may also move up and down in accordance with the up and down movement of the placing section 2 . That is, the loading stage 210 transferred by the transferring means 41 is placed on the placing means 42 . The placing means 42 itself may move up and down, and the placing section 2 may also move up and down accordingly. As the loading unit 2 moves up and down in this way, the loaded stage cargo 210 can be loaded onto the stage to be loaded.

(Overall picture)
FIG. 16 is a perspective view of the periphery of the loading mechanism according to Embodiment 2 of the present invention. A state in which a load 200 transferred by a transfer mechanism 40 is loaded from a loading unit 2 onto a car carriage 100 is shown as viewed from the car carriage 100 side.

The loading mechanism 20 includes a frame 52 and a control box 51 as required. The control box 51 stores the operation by the operator and the base and operation mechanism necessary for the operation.

The loading stage 210 transferred by the transferring means 41 is placed on the placing section 2 by the placing means 42 . As described in the first embodiment, the loading section 2 makes the loaded stage 210 form a mountain when the width is exceeded. FIG. 16 shows this state. In addition, the mountain-shaped load stage cargo 210 is loaded on the lowest first stage of the car carriage 100 .

A second load level cargo 210 is further loaded on top of the first load level cargo 210 formed in a mountain shape. In the process of this loading, the mountainous state is flattened, and finally flattened and the cargo 200 is loaded in a plurality of stages. The state on the right side of FIG. 9 is obtained.

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 is sequentially loaded on each of the stages of the car carriage 100 by the loading mechanism 20 . Finally, the car truck 100 loaded with the necessary cargo 200 is handed over to the next stage.
