Description

  The present invention relates to a collapsible pillar pallet for storing products in a stacked state in a container and transporting products.

  Conventionally, a standard type container has been used as a transport container, and a pillar pallet for accommodating the container has been used having a size that can respond to the height of the container. However, in recent years, based on the rationalization of transportation and the use of large trucks, high cube type containers whose height dimensions are set higher than those of standard types have been widely adopted. Such a tendency is remarkable particularly in containers used for export.

However, when the existing column pallets are stacked and stored in the above high cube type container (normally two column pallets are stacked vertically), a space will be created above the container. . Therefore, supply of pillar pallets corresponding to high cube type containers has been demanded.

  On the other hand, in the case of the above-described pillar pallet, in the case of return transportation after product transportation, it is customary to load the container in a container folded in a flat state (usually eight-stage vertical loading). The pillar pallet must be foldable.

  However, in the conventional column pallet that can be folded, the length of the column body is inevitably limited because the column body at the four corners is collapsed on the bottom plate by a horizontal body when folded.

  That is, in the conventional column pallet, as shown in FIG. 14, the bottom end of the column A is in contact with the bottom b of the guide tube B attached to the four corners of the bottom plate, that is, the column A is stably raised. In order to make it easier, the column A is raised with the lower end of the column A in contact with the bottom b, and when it is folded, the column A is tilted in a slightly raised state so that it falls on the pallet bottom plate C with a horizontal body. It was what was comprised (for example, refer patent document 1). Therefore, in this case, the length of the column A is set to a length within the lateral width of the pallet bottom plate C so that it can be folded into a horizontal body.

Japanese Utility Model Publication No.59-89829

  In the case of the column pallet having the above-described form, the height of the column is regulated by the size of the pallet bottom plate C. Therefore, when the column height is simply set to be long so as to be compatible with a high cube type container, as shown in FIG. 15, the tip of the column A hits the other side when tilted. It was impossible to fold this with a horizontal body, and it was forced to become a mountain-shaped folded state.

  In order to avoid the occurrence of such a situation, it is considered that the width of the pallet bottom plate C should be widened according to the length of the column, but the dimensions of the pallet bottom plate C are loaded when these are various. In addition, it has been standardized to have a predetermined size for generating wrinkles on the stack, and therefore, it has been considered difficult to provide a column pallet in which only the column pallet height is increased.

  The present invention solves such a problem, and it is possible to secure the length of the column that can be rationally adapted to a high cube type container without causing its folding hindrance. A new pillar pallet configured as described above is provided.

  In the present invention, a columnar supporting leg 2 having a U-shape is fixed to four corners of a bottom plate 1 having a rectangular frame shape with the open surface facing inward. The column body 4 having a length that can be lowered on the bottom plate 1 and for attaching the side wall material is supported with respect to the column body supporting legs 2 so as to be able to move up and down and fall down freely. The present invention relates to a foldable pillar pallet configured to be fixed in a state of being floated to a predetermined height from the upper surface.

  Further, according to the present invention, as described in claim 2, the columnar support legs 2 having a planar U-shape are fixed at the four corners of the bottom plate 1 having a rectangular frame shape with the open surfaces facing inward. And a guide plate 8 in which a cam inclined edge 8b for guiding a stopper pin 9 to be described later is formed on the inner side edge, is fixed to the column supporting leg 2 and the supporting leg is fixed. A longitudinal hole 2b is provided symmetrically on the front and rear surfaces of the body 2, and the lower end of the longitudinal hole 2b faces the upper surface of the bottom plate 1 and the upper end of the column body 4 described below is higher than the upper surface of the bottom plate 1. A column 4 for attaching to the side wall is provided at the lower end of the column 4 so that it can be moved to a state where it can float to the extent that it can be moved over the bottom plate 1 and attached to the side wall. By inserting the attached guide pin 4a into the vertically long hole 2b so as to be rotatable and slidable. Thus, the movement of the lower end portion of the column body 4 is controlled to be movable up and down and rotatable, and a stopper pin 9 fixed in a penetrating manner at a predetermined position of the column body 4 is provided with the column body 4. 4 is brought into contact with the cam inclined edge 8b in order to guide the movement at the time of standing up and down with 4 raising and lowering, and receiving the stopper pin 9 when the column body 4 moves to a predetermined standing state. The collapsible column pallet is characterized in that a receiving groove for fixing the column 4 at a position where the column 4 is floated by a predetermined height is formed at the top of the support leg 2 and the guide plate 8. Related.

  According to the present invention, the opening / closing wall 7 attached to the front and back surfaces of the bottom plate 1 and capable of being folded in the front half and the rear half of the bottom plate 1 in a folded state is provided at a predetermined height. The foldable column pallet according to claim 1 or 2 configured to be fixed to the column body 4 in the raised state is an embodiment.

  According to the present invention, the open / close wall 7 composed of the upper half wall 7b and the lower half wall 7a that can be folded is attached to the column body 4 fixed in the raised state. The hooking projections 7d fixed on both side portions near the upper end of the part wall 7a are hooked to the hooking groove metal fittings 7e provided on the corresponding part of the column body 4, thereby detachably stabilizing. The upper half wall 7b is designed to be freely opened and closed by allowing a cannula ridge 7c provided at the upper end portion to enter the column 4 side, and the hook metal fitting 10 having the horizontal ridge portion 10a is attached to the end of the bottom plate 1. At the lower edge of the lower half wall 7a of the opening / closing wall 7, a slit piece 11 having a slit in which the horizontal hook portion 10a of the hook metal fitting 10 is slidably fitted at a symmetrical position near both sides of the edge is provided. Mounting, the length of the slit is a column body in which the upper end edge of the opening and closing wall 7 is fixed in the raised state 4 is set to have a length that allows the push-up to a position where it can be hooked at the upper end thereof, and the slit piece when the opening and closing wall 7 is tilted inward. 11 is slid to move the opening / closing wall 7 forward, and at the same time, the upper half wall 7b is folded over the lower half wall 7a, so that the bi-folded opening / closing wall 7 becomes the bottom plate 2 The collapsible pillar pallet according to any one of claims 1 to 3, wherein the collapsible pillar pallet is configured to be folded in a state where it is positioned at a half of the first embodiment.

  In the present invention, a columnar supporting leg 2 having a U-shape is fixed to four corners of a bottom plate 1 having a rectangular frame shape with the open surface facing inward. The column body 4 having a length that can be lowered on the bottom plate 1 and for attaching the side wall material is supported with respect to the column body supporting legs 2 so as to be able to move up and down and fall down freely. Since it is configured to be fixed in a state of being floated to a predetermined height from the upper surface, the column body 4 has a length that can be lowered on the bottom plate 1 when folded, but is pulled upward when standing. By maintaining the state, it functions as a tall column. Therefore, the column pallet can be accommodated in a very neat form with respect to a high cube type container which is taller than a normal container.

In other words, in the case of a conventional pallet, the height of the pillar is matched to the regular type container, so when it is loaded into a high cube type container, there is a wasteful space above the container due to its height. The problem that it occurs, and when using a tall column body, there arises a problem that the folding of the column is caused (see Fig. 15). It will be eliminated. That is, the pallet according to the present invention can be folded into a flat state like a normal pallet at the time of folding, even though the column body becomes high at the time of assembly, so that such transportation efficiency can be improved. That is why.

  The pillar pallet according to the present invention is a tall pallet when it is used, but when it is folded, it becomes the same height as a normal pallet, so a high cube type container can be used for return transportation after use. By using it, the transportation cost can be reduced based on the possibility of accommodating many pallets. In other words, although it functions as a tall pallet, it can be flattened to the same size as a normal pallet when folded, and thus does not cause an increase in space for housing the container.

  According to the present invention, a columnar support leg 2 having a U-shape is fixed to four corners of a bottom plate 1 having a rectangular frame shape with its open surface facing inward. At the same time, a guide plate 8 in which a cam inclined edge 8b for guiding a stopper pin 9 to be described later is formed on the inner side edge is fixed to the column supporting leg 2, and the supporting leg 2 A longitudinally long hole 2b is opened symmetrically on the front and rear surfaces, and the lower end of the elongated hole 2b faces the upper surface of the bottom plate 1, and the upper end of the column body 4 described below is the required height from the upper surface of the bottom plate 1. A column 4 for attaching a side wall material is attached to the lower end of the column 4 so as to face a position where it can be moved to a floating state. By inserting the guide pin 4a into the vertically long hole 2b so as to be rotatable and slidable, The movement of the lower end portion of the column body 4 is controlled so as to be movable up and down and rotatable, and a stopper pin 9 fixed in a penetrating manner at a predetermined position of the column body 4 is provided on the column body 4. In order to guide the movement at the time of standing up and down with raising and lowering, and contacting the inclined edge 8b for the cam, and receiving the stopper pin 9 when the column body 4 moves to a predetermined standing state, Since the receiving groove for fixing the body 4 at a position where the body 4 is floated by a predetermined height is formed in the overlapping top portion of the supporting leg 2 and the guide plate 8, as described in claim 1 There will be an effect.

  At the same time, the “pushing up” and “falling” operations of the column 4 are performed by “inserting the guide pin 4a attached to the lower end of the column 4 into the vertically long hole 2b so as to be rotatable and slidable. Since the movement of the lower end portion of the body 4 is controlled so as to be movable up and down and turnable, the movement is extremely smoothly and reliably performed. Further, by pushing the stopper pin 9 in contact with the cam inclined edge 8b in order to guide the movement at the time of standing up and down accompanying the raising and lowering of the column body 4, the column pushing operation Since the stopper pin 9 is in contact with the cam inclined edge 8b, a part of the weight of the column body 4 is received by the cam inclined edge 8b, which reduces the manpower required for the column push-up operation. This greatly contributes to the smooth operation of the operation.

  According to the present invention, the opening / closing wall 7 attached to the front and back surfaces of the bottom plate 1 and capable of being folded in the front half and the rear half of the bottom plate 1 in a folded state is provided at a predetermined height. By being configured to be fixed to the column body 4 in the raised state, the opening / closing wall 7 is raised in proportion to the pushing-up of the column body 4, and the upper edge of the opening / closing wall 7 is the column body 4. It is possible to adjust the position according to the height of the.

  According to the present invention, the open / close wall 7 composed of the upper half wall 7b and the lower half wall 7a that can be folded is attached to the column body 4 fixed in the raised state. The hooking projections 7d fixed on both side portions near the upper end of the part wall 7a are hooked to the hooking groove metal fittings 7e provided on the corresponding part of the column body 4, thereby detachably stabilizing. The upper half wall 7b is designed to be freely opened and closed by allowing a cannula ridge 7c provided at the upper end portion to enter the column 4 side, and the hook metal fitting 10 having the horizontal ridge portion 10a is attached to the end of the bottom plate 1. At the lower edge of the lower half wall 7a of the opening / closing wall 7, a slit piece 11 having a slit in which the horizontal hook portion 10a of the hook metal fitting 10 is slidably fitted at a symmetrical position near both sides of the edge is provided. Mounting, the length of the slit is a column body in which the upper end edge of the opening and closing wall 7 is fixed in the raised state 4 is set to have a length that allows the push-up to a position where it can be hooked at the upper end thereof, and the slit piece when the opening and closing wall 7 is tilted inward. 11 is slid to move the opening / closing wall 7 forward, and at the same time, the upper half wall 7b is folded over the lower half wall 7a, so that the bi-folded opening / closing wall 7 becomes the bottom plate 2 By being configured to be folded in a state in which it is located at a half portion, the provision of the opening / closing wall 7 exhibiting the action as claimed in claim 3 is realized, and at the same time, the opening / closing wall 7 is extremely Smooth and reliable pulling and folding can be achieved.

Reference numeral 3 denotes a mounting sled, which is installed between the pillar supporting legs 2 facing front and rear (see FIG. 2).

  Reference numeral 4 denotes a prismatic columnar body, which is attached to the above-described columnar supporting leg 2 so as to be foldable inward. The present invention uses the foldable mounting structure as the first principal technology of the invention, and the structure will be described in detail later.

  Reference numerals 5 and 5 are side wall members, and are configured so that left and right side walls are formed by attaching between right and left front and rear pillars and between left and right front and rear pillars in pillars standing at four corners. It is.

  7 is an opening / closing wall on the front side, and an upper half wall 7b is hinged above the lower half wall 7a so as to be freely opened and closed. The product or the like is accommodated mainly by opening the upper half wall 7b forward. 7c is a cannula attached to both sides of the upper edge of the upper half wall 7b, and the upper half wall 7b is controlled to be opened and closed by detachably hooking on the fitting provided on the column 4 side. It is configured to manage. 7d is a latching projection piece fixed on both sides near the upper end of the lower half wall 7a, and can be attached and detached by hooking it to a latching grooved fitting 7e provided on the column body 4 side. It is configured to be stabilized.

  Although not shown in the drawings, the rear side opening / closing wall having the same form as the front side opening / closing wall 7 is attached to the column located on the back side by the same means as described above. It is configured.

  In the present invention, the opening / closing control mechanism of the opening / closing wall 7 is the second essential configuration of the invention, which will be described in detail later.

  By the way, in the embodiment shown in the drawings, the side wall material 5 and the opening / closing wall 7 are formed of a net material to form a so-called “net pallet”. It may be configured to be That is, in the present invention, the folding form of the column 4 and the opening / closing wall 7 has the characteristic as a device, and the form of the pallet itself is not particularly limited.

  Next, a description will be given of a mounting configuration of the column body 4 to the support leg 2 as a first technical main part of the present invention. As shown in FIG. 4, vertically long holes 2b are symmetrically opened on the front and rear surfaces of the supporting leg 2 having a U-shape. The lower end of the vertically long hole 2b faces the upper surface of the bottom plate 1, and the upper end of the vertically long hole 2b is positioned so that the column body 4 can be moved to a state where it floats from the upper surface of the bottom plate 1 by a required height. It is configured to be exposed to.

  Further, as described later, a guide pin 4a attached to the lower end of the column body 4 is fitted into the vertically long hole 2a so as to be rotatable and slidable, thereby controlling the movement of the lower end portion of the column body 4. It is constituted as follows. Furthermore, a receiving groove 2c for hooking a stopper pin 9 provided on a column body to be described later is formed in the central portion of the upper edge of the supporting leg 2.

  Reference numeral 8 is a guide plate stretched on the outer surface side of the support leg 2 described above, and an upper edge of the guide plate overlaps with the receiving groove 2c and latches the stopper pin 9 of the column 4 together. And a guide pin for guiding the stopper pin 9 of the column body 4 to the side edge of the inside of the receiving groove 8a so as to be received by the overlapping portion of the receiving groove 2c and the receiving groove 8a. An inclined edge 8b for use is formed.

  Reference numeral 9 denotes a stopper pin attached so as to penetrate a predetermined portion near the lower end of the column body 4 (see FIG. 5). In the state where the column body 4 is tilted horizontally, the stopper pin 9 is attached to the cam inclined edge 8b. It is comprised so that it may be located in the state which contacted. When the column body 4 is raised to the vertical state, the stopper pin 9 can be raised while the column body 4 is pulled upward by being performed in a state in which the stopper pin 9 is kept in contact with the cam inclined edge 8b. It is configured so that it can.

6 to 9 show the displacement stroke of the column 4 from the rising state to the horizontal folded state.
That is, as shown in FIG. 6, in the state where the column 4 is raised, the state where the column body 4 is raised by the distance L from the conventional position shown in FIG. 14 is maintained. That is, the lower end of the column 4 is based on the lower end stability maintaining action by the guide pin 4a engaging with the vertically long hole 2a and the locking action by the stopper pin 9 entering the receiving groove 2c and the receiving groove 8a. , Kept steady and stable. And based on the stabilization in such a raised state, the columnar body 4 is maintained in height without increasing its length dimension.

  At the time of folding, the locking action of the stopper pin 9 is canceled by slightly lifting the column 4 as shown in FIG. After that, as shown in FIG. 8, the column 4 is rotated in the tilting direction while the stopper pin 9 is in contact with the cam inclined edge 8b, and is horizontally inclined as shown in FIG. At this time, since the guide pin 4a provided at the lower end of the column 4 moves from above to below the vertically long hole 2a, the column 4 is in a horizontal state without its tip being caught on the other side. be able to. Then, if the column body 4 on the opposite side (left side in the front view) is tilted in the same manner, the column body 4 is tilted in a horizontal state above the right column body that is tilted to the horizontal body as described above. The height position based on the overlapping of the right column and the left column is adjusted based on the mobility of the guide pin 4a in the vertically long hole 2a, thereby achieving the purpose of overlapping in a completely parallel state. Will be.

  That is, by pulling up the column 4 at the time of assembly and increasing its height, the length of the column 4 itself can be set to an optimum height for loading on a high cube type container. Since the length is the same as that of a normal one, the column body 4 is pulled downward when folded, so that folding with a horizontal body similar to the conventional one is permitted.

  Next, the second technical main part of the present invention is the mounting structure of the opening / closing wall 7. That is, as described above, the opening / closing wall 7 to be fixed to the column body 4 is required to have a height corresponding to the column body 4 because the column body 4 is raised while being lifted upward. However, if the height is simply increased, it will not be possible to fold it horizontally on the bottom plate 2 when converted to the folded state. This is because the opening and closing wall is overlapped with the front half of the bottom plate 2 in a state where the front side is folded in two, so that when the back side opening and closing wall is folded in two and folded, It is important to be folded in a state in which the leading edges of each other are matched with each other, that is, in a state in which both form a horizontal plane. However, when the height dimension of the opening / closing wall 7 is increased, such a folded form cannot be adopted, and the end portion overlaps in a mountain shape.

  Accordingly, the present invention has a second technical main feature that the above-described problem is solved by adopting the following configuration.

  In FIG. 1, reference numeral 10 denotes a hook metal fitting having a horizontal flange 10a, which is attached to a symmetrical position near both end portions of the bottom plate 1 so as to be raised and lowered. Reference numeral 11 denotes a slit piece provided with a slit for slidably fitting the horizontal flange portion 10a of the hook metal fitting 10, which is attached to the lower edge of the lower half wall 7a of the opening / closing wall 7. Then, the slit piece 11 reaches the position at which the upper end edge of the opening and closing wall 7 can correspond to the upper end (can be latched) with respect to the column 4 fixed in the raised state as described above. The slit length is set so as to allow the push-up of.

  12 is a stopper frame suspended from the inside of the slit piece 11, and 13 is a restraining piece for restraining the stopper frame 12 on the front side thereof, and protrudes from the center of the edge of the bottom plate 1. is there. When the opening / closing wall 7 is in the rising state (assembled state) as shown in FIG. 1, the stopper frame 12 prevents the movement that is pushed forward by the restraining piece 13. In addition, when the opening / closing wall 7 is pulled up as shown in FIG. 10 for folding, the blocking is released. The pulling height is configured to be regulated by the slit length of the slit piece 11. In such a pulling up operation, the hooking protrusions 7c fixed on both sides near the upper end of the lower half wall 7a are hooked to the hooking grooved fittings 7d provided on the column body 4 side. This is to eliminate (leave).

  11 to 13 show the folding process of the opening / closing wall 7, and in the assembled state as shown in FIG. 11, by lifting the entire opening / closing wall 7 as described above, The piece 7d is detached from the latching grooved fitting 7e provided on the column body 4 side (at this time, the latch of the kanuki 杆 7c is removed), and as shown in FIG. Defeat inward. After that, as shown in FIG. 13, the slit piece 11 is slid to move the opening / closing wall 7 forward, and at the same time, if the upper half wall 7b is folded over the lower half wall 7a, The bi-folded open / close wall 7 is folded in a state where the open / close wall 7 is positioned at a half portion of the bottom plate 2. Therefore, by folding the open / close wall on the back side in the same manner, the front edges of the two sides are matched with each other without overlapping the front side one in a mountain shape, that is, both sides form a horizontal plane. It will be folded in a state.

  The folding operation of the opening / closing wall 7 is performed prior to the folding of the column body 4 described above, and the side walls attached to the left and right column bodies are overlapped on the front and rear opening / closing walls in the folded state. It is configured so that it can be folded. (See Figure 2)

  Reference numeral 14 denotes a belt insertion fitting attached to the front and rear edges of the bottom plate 1 for inserting a fastening belt for auxiliary fixing of the accommodated product.

  In the pallet according to the present invention having the above-described configuration, in the assembled state as shown in FIGS. 1 and 2, the column body 4 and the opening / closing wall 7 are maintained in the state of being pulled upward as described above. Therefore, the height of the pallet is set to be extended. In other words, when loading a large number of high cube type containers with the required number of layers stacked (usually two levels), the optimum height for loading (a high space that does not cause useless space above) 3), the extension setting can be made.

  Next, when folding the pallet in the assembled state, first, the latch of the cannula 7c is removed, and the latch groove for latch provided on the column body 4 side by slightly lifting the opening and closing wall 7 is used. Detach from the metal fitting 7d. After that, it is folded in half while being folded down to the inner side of the pallet, and the opening and closing wall 7 is moved forward by sliding the slit piece 11 as shown in FIG. Is folded in a state where it is positioned at a half portion of the bottom plate 2.

  By performing such an operation on the opening / closing wall on the back side, the both opening / closing walls are folded on the bottom plate 1 with the upper surface thereof being flattened. The above-described “extension of the height” of the opening / closing wall is eliminated based on the above-mentioned “sliding the slit piece 11 to move the opening / closing wall 7 forward”, and the opening / closing wall is a normal opening / closing wall. The bottom plate 1 has a standardized size and can be folded without colliding with the front and back side opening and closing walls. .

  Next, if the column body 4 which makes a pair on the right side when viewed from the front side is slightly lifted and then tilted inward, it is overlapped on the open / close wall 7 in the folded state. The material 5 is also brought down at the same time and converted into a stacked state. The pallet and the folding work are completed by performing the same operation on the pillars 4 paired on the left side when viewed from the front, and stacking them on the upper surface of the right pillar body in the above-mentioned lying state. And since the “extension of the height” of the column is based on the support in the floating state, the “floating” part by simply defeating it becomes only the “mounting height”. The length itself is the same as that of the existing pallet. Therefore, in such a lying state, it matches the size of the bottom plate 1 in the same manner as a normal column, so it is overlapped with a mountain shape. There is no flat folding. The above-described change in the “mounting height” is made flexible by sliding in the “longitudinal hole 2b”. Therefore, the height position can be changed so that the pillars in the lying state are superposed with no gap therebetween. Therefore, it is possible to make the folded state in which everything including the opening and closing wall is perfect.

  When transported in such a folded state (returned transport of only the pallet), if it is stored in a high cube type container in a stacked state as shown in FIG. In the case of containers, the stacking of about 8 levels can be stacked up to about 10 levels, so that the transportation cost can be reduced.

  Based on the above, the economics of transportation costs will be improved on the basis of the new structure of the purpose of the pallet according to the present invention, which is adapted to the rational use of high cube type containers.
