As described above, the pallet and the loading device according to the present invention have the following effects due to their configurations.
Three or more lower guide members are fixed to one side of the lower structure or the intermediate structure in parallel in the X-axis direction, and three or more lower guided members fixed to the other of the lower structure or the intermediate structure are three. Since the lower guide member is guided by the pair of guide surfaces arranged in series in the Y-axis direction so as to be movable along the X-axis, when a load is supported by the intermediate structure, three or more lower parts are provided. When a pair of guide surfaces in series in the Y-axis direction of the guide member guides three or more lower guided members and is accelerated in the horizontal direction by an earthquake or the like, the intermediate structure and the lower structure are along the Y-axis. It moves relatively horizontally and exhibits seismic isolation and vibration control functions.
In addition, if the concentrated load is applied downward, the three or more lower guide members are juxtaposed in the X-axis direction to the lower structure that is easily bent along the X-axis, so that the load is supported by the intermediate structure. Then, the load of the load acts on the lower structure and is easily bent along the X axis, and a pair of guide surfaces in series in the Y axis direction of the three or more lower guide members becomes three or more lower guided members. When guided in a substantially uniform manner and accelerated in the horizontal direction by an earthquake or the like, the intermediate structure and the lower structure move relatively horizontally along the Y-axis to exhibit seismic isolation and vibration control functions.
In addition, since the pair of guide surfaces of the plurality of the lower guide members having three or more pieces have the same contours when viewed horizontally with the line of sight parallel to the X axis, the intermediate structure is When moving in the Y-axis direction while being guided by the lower structure, the intermediate structure can move while maintaining substantially horizontal with respect to the lower structure.
Further, among the three or more lower guide members, the pair of first lower guide members arranged in the X-axis direction can be the base member and the pair of rail members, and among the three or more lower guided members, The first lower guided member guided by the first lower guide member is composed of a pair of axles and a pair of wheels, and a pair of elongated holes provided at both ends of the pair of axles in the base member. So that the pair of wheels can roll along a pair of rail members, so that the two ends of the axle are guide elongated holes at two positions in the X-axis direction. The wheel can be guided to roll in the Y-axis direction, and can be prevented from coming off when the lower structure and the intermediate structure move relatively in the Y-axis direction.
In addition, the lower structure extends in the Y-axis direction and has a pair of beam-like lower structure portions, a first plate-like lower structure portion provided so as to be sandwiched from both sides in the X-axis direction, and a pair of beam shapes Since the second plate-like lower structure portion connecting the lower structure portions can be formed, when the load of the load is applied downward to the lower structure body, the lower structure causes the X-axis to be moved by the plate-like structure portion. It is easy to bend in the vertical plane including the beam, and the beam-like lower structure portion makes it difficult for the lower structure to be bent in the vertical plane including the Y axis.
Further, when the concentrated load is received downward, one of three or more upper guide members or upper guided members is juxtaposed in the Y-axis direction with the upper structure that is easily bent along the Y-axis. Since the other of the three or more upper guided members or the upper guide members supported by the upper and lower guide members is movable along the pair of guide surfaces, the load of the load is increased when the load is supported by the upper structure. Acting on the structure, it is easy to bend along the Y-axis, and a pair of guide surfaces in series in the X-axis direction of three or more upper guide members are guided in contact with the three or more upper guided members substantially evenly. When accelerated in the horizontal direction due to an earthquake or the like, the upper structure and the intermediate structure move relatively horizontally along the X-axis to exhibit seismic isolation and vibration control functions.
In addition, since the upper structure body is provided with an upper dent that can fit the lower part of the load on the upper surface, the load is placed on the upper structure, and the lower part of the load is placed on the upper dent provided on the upper structure body. When fitted, even if the upper structure moves horizontally in the X-axis direction and the Y-axis direction, it is difficult for the luggage to come off the upper structure.
Further, when the luggage is placed on the pallet and the lower part of the luggage is fitted in the upper depression, and the intermediate pallet is placed on the luggage and the upper part of the luggage is fitted in the intermediate depression, the pulling member extending vertically The upper and lower ends are connected to a plurality of locations around the pallet and a plurality of locations around the intermediate pallet so that tension can be generated inside the tension member. Are moved horizontally in the X-axis direction and the Y-axis direction, making it difficult for the load to come off the pallet.
Accordingly, it is possible to provide a pallet for loading a load capable of exhibiting a seismic isolation and vibration control function with a simple configuration and a loading device for loading a plurality of loads.

A case where an earthquake occurs with a load placed on a pallet will be described as an example.
The earthquake accelerates the pallet in the horizontal direction.
The lower structure 100 and the intermediate structure 200 move relatively horizontally in the Y-axis direction.
The intermediate structure 200 and the upper structure 300 move relatively horizontally in the X-axis direction.
Between the lower structure 100 and the intermediate structure 200, the lower guide member 120 and the lower guided member 220 move relatively horizontally in the Y-axis direction, and the wheels of the first lower guided member 221 move to the first lower portion. A frictional force is generated between the wheel and the bush that rolls on the guide surface W of the guide member 110, and the horizontal acceleration in the Y-axis direction acting on the lower structure 100 is attenuated.
Between the intermediate structure 200 and the upper structure 300, the upper guide member 320 and the upper guided member 230 move relatively horizontally in the X-axis direction, and the wheels of the first upper guided member 231 move to the first upper guiding member. A frictional force is generated between the wheel and the bush that rolls on the guide surface W of 321, and the horizontal acceleration in the X-axis direction acting on the lower structure 100 is attenuated.
Accordingly, the horizontal acceleration acting on the lower structure 100 is attenuated to be reduced and transmitted to the load.
In particular, in the stacking apparatus described above, a slight side slip occurs between the intermediate pallet 400 and the drum can 10 within the gap between the drum can and the recess G, and further the horizontal acceleration is attenuated.

Moreover, the pallet and the loading apparatus according to the embodiment of the present invention have the following effects depending on the configuration.
Three or more lower guide members 120 are juxtaposed in the X-axis direction in the lower structure 100, and three or more lower guided members 220 supported by the intermediate structure 200 are arranged in the Y-axis direction of the three or more lower guide members 120. Since the guide is guided by the pair of guide surfaces W in series, when the load is supported by the intermediate structure 200, three pairs of guide surfaces W in series in the Y-axis direction of three or more lower guide members 120 are provided. When the lower guided member 220 is guided and accelerated in the horizontal direction by an earthquake or the like, the intermediate structure 200 and the lower structure 100 move relative to each other along the Y axis to perform seismic isolation and vibration control functions. Demonstrate.
Further, since the three or more lower guide members 120 are juxtaposed in the X-axis direction on the lower structure 100 that is easily bent along the X-axis if a concentrated load is applied downward, the load is supported by the intermediate structure 200. Then, the load of the load acts on the lower structure 100 and is easily bent along the X axis, and a pair of guide surfaces W in series in the Y axis direction of the three or more lower guide members 120 has three or more lower guided members. When guided in contact with the member 220 substantially evenly and accelerated in the horizontal direction due to an earthquake or the like, the intermediate structure 200 and the lower structure 100 move relatively horizontally along the Y axis to provide seismic isolation and vibration control functions. Demonstrate.
Further, since the pair of guide surfaces W of the three or more lower guide members 120 have the same contour when viewed horizontally along the X axis, the intermediate structure 200 is the lower structure 100. When moving in the Y-axis direction, the intermediate structure 200 can move while maintaining substantially horizontal with respect to the lower structure 100.
In addition, the first lower guide member 121 separated in the X-axis direction among the three or more lower guide members 120 may be a base member and a pair of rail members, and the first of the three or more lower guided members 220 may be the first one. The first lower guided member 221 guided by the one lower guiding member 221 is made of a pair of axles and wheels,
Since both ends of a pair of axles fit in a pair of elongated holes provided in the base member and move in the Y-axis direction, a pair of wheels can roll along a pair of rail members. Both ends of the axle are guided by the guide slot S at both outermost positions in the X-axis direction so that the wheel can roll in the Y-axis direction, and the lower structure 100 and the intermediate structure 200 move relatively in the Y-axis direction. However, it can be prevented from coming off.
The lower structure 100 extends in the Y-axis direction and is spaced apart from a pair of beam-like lower structure parts 111 and a first plate-like lower structure part 112 provided so as to be sandwiched from both sides in the X-axis direction. Since the plate-like lower structure portion 113 can be used, if a concentrated load is applied to the lower structure 100 downward, the plate-like structure portion causes the lower structure 100 to bend easily in a vertical plane including the X axis. The lower structure portion 111 makes it difficult for the lower structure 100 to bend in a vertical plane including the Y axis.
Further, if a concentrated load is applied downward, three or more upper guide members 320 are juxtaposed in the Y-axis direction on the upper structure 300 that is easy to bend along the Y axis, and three or more upper guide members 320 are supported by the intermediate structure body. Since the upper guided member 230 is guided by the pair of guide surfaces W in series in the X-axis direction of the three or more upper guide members 320, when the load is supported by the upper structure 300, the load of the load is increased. A pair of guide surfaces W that act on the structure 300 and easily bend along the Y-axis and are in series in the X-axis direction of the three or more upper guide members 320 are in contact with the three or more upper guided members 230 substantially evenly. The upper structure 300 and the intermediate structure 200 move relatively horizontally along the X axis and exhibit seismic isolation and vibration control functions.
In addition, since the upper structure body 310 is provided with an upper dent that is a dent that can fit the lower part of the load on the upper surface, the load is placed on the upper structure 300, and the lower part of the load is provided on the upper structure body 310. If the upper structure is horizontally moved in the X-axis direction and the Y-axis direction, it is difficult for the luggage to be detached from the upper structure 300.
Further, when the load is placed on the pallet and the lower portion of the load is fitted in the upper recess, and the intermediate pallet 400 is placed on the load and the upper portion of the load is fitted in the intermediate recess, the upper and lower ends of the pulling member extending vertically Are connected to a plurality of locations around the pallet and a plurality of locations around the intermediate pallet 400 so that tension can be generated inside the tension member, so that the intermediate pallet 400, the load and the upper structure are integrated with each other. It moved horizontally in the axial direction and the Y-axis direction, making it difficult for luggage to come off the pallet.
