Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, for example, binds various kinds of goods stacked in a stacked manner on a pallet or a pallet for cargo handling to prevent the load from being collapsed, and when it is not in use, it is rolled up into a compact. The present invention relates to a load collapse prevention device for transported goods.

[0002]

[Prior art]

 Corrugated boxes, cases, and other items packed with various foods, products, products, etc. should be stacked and stacked on a loading platform such as a pallet or cart for the purpose of transporting and storing them all together. By loading and moving from one loading platform to another, loading and unloading on a truck loading platform, storage in a warehouse, and so on are performed. In particular, when transporting by trucks, etc., since overloading is being strictly regulated to ensure safety, etc., it is possible to stack it on top of it using a pallet to ensure an appropriate loading capacity. However, the number of such pallet transportation methods has recently increased, and they are very important.

[0003] In order to prevent the cargo loaded on the loading platform from being overloaded when moving or unloading the cargo by such a pallet transportation method, conventionally, the circumference of the loaded cargo is transparent. The belt-shaped sheet made of vinyl chloride resin is fixed many times to prevent it from collapsing or scattering around the transported objects. The vinyl chloride resin sheets are wound around and fixed to each other by wrapping them around the objects loaded on the loading platform and using the adhesiveness of the sheets themselves to stack them.

Further, for example, at the time of shipping from a large-scale product processing plant, a packaging device that surrounds the entire transported object on the loading table is prepared in advance, and a shrinkage property made of a synthetic resin covering the entire transported object is provided. It is also fixed by shrink-wrapping the sheet by heat shrinkage.

Further, various types of pallets for cargo handling, and various pallets for preventing a load from collapsing by winding a belt-shaped belt-like sheet around the peripheries of various objects stacked in a trolley on a truck to bind them together have been devised. ing.

[0006]

[Problems to be solved by the device]

 The above-mentioned conventional wrapping fixing of a vinyl chloride resin sheet is impossible because the sheet itself cannot be reused when it is no longer needed when taking out a product, etc. It is discarded as it is. However, if it is incinerated when it is discarded, not only will it cause toxic gas and foul odor, causing pollution problems that pollute the surrounding environment, but it will also become expensive in terms of price, and will also be transported. It was a very troublesome work to fix the rolls around the object many times.

On the other hand, in the case of shrink wrapping, a large wrapping device is required, and it is completely useless if it is sufficient to prevent the collapse of the load temporarily, and moreover, the above-mentioned sheet. As in the case of wrapping by wrapping, even if a necessary part of the sample is taken out from the transported object, the whole must be broken, and even if part is broken, the load collapses after breaking. It was extremely difficult to repair to prevent this.

In addition, in the case of a conventional belt structure seat, when it is installed in a rolling manner, the initially rolled or folded seat is unfolded and then the seat is gradually abutted from one end thereof. Since the periphery of the transported object is fixed around the carrier, the other end of the seat cannot be reached by the operator and is left in a loose state by leaving it to the operator's own weight. The operation was troublesome. In addition, when removing the sheet that is fixed to the object to be transported, it is impossible to put it in a compact state immediately, which is a hindrance, and there is a problem that handling after removal is complicated. Furthermore, when the sheet is stored, it is unstable if it is simply rolled up, and it must be tied with a string or the like, and if it is simply folded, the sheet itself will be wrinkled or loose. There were some drawbacks such as the tendency to break.

Therefore, the present invention has been devised in view of the existing circumstances such as the above, and various types of transports stacked in a stacked manner on a loading platform such as a pallet for cargo handling and a trolley. Items are bundled and fixed and loaded onto and unloaded from a truck bed to prevent the cargo from being overloaded during storage and other purposes in the warehouse.In addition, the attachment and detachment work is easy, and it can be repeatedly used without waste. It is an object of the present invention to provide a load collapse prevention device for a transported object that can be compactly stored by being semi-automatically wound when not needed and can be easily carried.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the present invention, there is provided a sheet cover 1 made of a sheet material having a length long enough to wind around the articles C stacked on a predetermined loading platform P. A fixing means 2 for connecting and fixing each other in a state where the end portions of the seat cover 1 are overlapped with each other, and a shape-retaining member made of a rigid material fixed to the seat cover 1 substantially orthogonal to the rolling direction of the seat cover 1. The sheet material 6 and the handle 7 arranged on the sheet cover 1 near the shape-retaining material 6, and the traction means 5 attached to the end portion of the seat cover 1 so that the end portions of the seat cover 1 are superposed and positioned, It is characterized in that it comprises a winding biasing means 3 which is arranged in a spread state along the rolling direction of the cover 1 and spirally biases the winding.

Further, the winding biasing means 3 can be configured as a spring member made up of a spiral spring, and further, each of the end portions of the seat covers 1 to be overlapped is provided with an inner portion of any one of the end portions. It is possible to form a slender outgoing slit 8 having a cutout opening for letting out the handle 6 of the other pulling means 5.

【Example】

 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, referring to the drawings, an embodiment of the present invention will be described. Reference numeral 1 shown in the drawings is a belt-shaped seat cover, which is stacked on a loading platform P such as a pallet or a trolley for cargo handling. As shown in FIG. 1, the various cargoes C loaded are horizontally wound around, and although not shown, they are long and wide enough to be swung vertically along with the loading platform P. It has and.

That is, the seat cover 1 is formed of, for example, a cloth material such as a nylon resin or polyester resin synthetic resin sheet cloth having a predetermined thickness. When the transported articles C are to be mounted in the horizontal direction, the width of the stacked articles C in the vertical direction, which is spanned over a plurality of steps, and the end portions are overlapped with each other. As described above, the length of the cargo C should be long enough to surround it in the horizontal direction (see FIG. 1). Further, in the case where the transported articles C are to be mounted in the vertical direction, the horizontal width of the stacked transported articles C is laid across a plurality of rows in the horizontal direction, and the transported article together with the loading platform P. It shall have a length sufficient to surround the article C in the up-down direction in a state in which the ends are overlapped with each other so that C can be wound (not shown).

Further, the seat cover 1 is provided with a fixing means 2 for connecting and fixing each other in a state where the end portions of the article C after the article C is wound around are overlapped with each other arbitrarily. The fixing means 2 can be attached to and detached from both side edges of the seat cover 1 in the longitudinal direction in the longitudinal direction between the outer surface of the inner portion and the inner surface of the outer portion which are overlapped with each other. A male and female hook-and-loop fastener is formed in a strip shape along the longitudinal direction of the seat cover 1. For example, by setting the female surface fastener on the outer surface of the inner part to be overlapped longer than the male surface fastener on the inner surface of the outer part Makes it easy to adjust the roll length. The fixing means 2 is not limited to the hook-and-loop fastener structure shown in the illustrated example, and the hooks, buckles and the like can be detachably attached so that the seat covers 1 can be fixed to each other. If it is, it is enough. Further, the seat cover 1 may be formed on both inner and outer side surfaces in the longitudinal direction at both end portions of the seat cover 1 so that either of both end portions to be overlapped may be an outer portion or an inner portion. It is possible to form the surface fastener itself as a dual-use structure.

As shown in FIG. 2, on both side edges of the seat cover 1 in the rolling direction, a winding biasing means 3 for helically biasing the entire seat cover 1 in a spiral shape is provided in the longitudinal direction of the seat cover. It is installed by enclosing or adhering in a spread state along the. As the urging force urging means 3, for example, a spiral spring, or a spring member such as a leaf spring biased in a folding manner, or a magnetic member that is magnetically attracted by urging is extended. Then, the seat cover 1 is enclosed or adhered in a bag portion formed on both side edges of the seat cover 1 itself, and when the seat cover 1 is not used, the entire seat cover 1 is automatically put into a folded state. It is structured so that it can be rotated and compacted. It should be noted that the arrangement of the winding biasing means 3 is not limited to both side edges of the seat cover 1, and it can be arranged, for example, on the center line of the seat cover 1 or at any other appropriate portion, and the number is one or two. Alternatively, it may be a plurality of three or more. In any case, as long as the seat cover 1 is in the released state, it can be compact and can rotate immediately in a spiral shape. The seat cover 1 may be rolled up into one roll from one end to the other end, or may be rolled into two rolls from both ends of the seat cover 1 toward the center. Is also good.

At both ends of the seat cover 1, traction means 5 for superposing the ends of the seat cover 1 on each other and positioning them are attached. As shown in the figure, the pulling means 5 is made of a rod-shaped rigid material fixed to the seat cover 1 substantially orthogonal to the rolling direction of the seat cover 1, for example, by being mounted in the seat cover 1. The shape-retaining material 6 and the handle 7 arranged on the approximate center line of the seat cover 1 near the shape-retaining material 6.

The shape-retaining material 6 is, for example, a band-shaped plate material made of aluminum that is mountain-folded and valley-folded along the longitudinal direction to be bent and formed in a zigzag cross section for reinforcement, or pipe material, bar material, and the like. This member is used and is housed in a bag portion formed at both ends in the longitudinal direction of the seat cover 1, for example. Then, with respect to the pulling direction when pulled by the handle 7, the entire width of the seat cover 1 at the pulling portion itself is not deformed or deformed and remains substantially straight, especially at both edge portions. Is to be surely towed. Further, the shape-retaining material 6 itself can be forcibly inserted between the stacked articles C and the seat cover 1 to be wound around the articles C can be temporarily fixed. (See Figure 3).

The handle 7 is formed of the same material as that of the seat cover 1, for example, as a loop-shaped cord material or a belt material on which a worker's finger or the like can be hung, and the entire seat cover 1 is pulled. It is designed so that it can withstand the traction load when carrying out. The grips 7 themselves are not limited to being arranged substantially on the center line of the seat cover 1, but may be arranged in pairs at positions near both ends of the shape retainer 6 or in the longitudinal direction of the seat cover 1. It is also possible to arrange a plurality of shape-retaining materials 6 in a direction directly intersecting with the shape-retaining material 6. Further, if necessary, they can be arranged at both ends of the shape-retaining material 6, that is, at both edges of the seat cover 1. In this case, formation of the exit slit 8 described later may not be required. The seat cover 1 may be provided with the traction means 5 on both the inner and outer side surfaces of the seat cover 1 so that either end of the seat cover 1 may be located outside or inside.

Further, as shown in the drawing, an elongated outward slit 8 is formed in the outer portion of the end portion of the seat cover 1 to be overlapped, the slit 7 being cut out so that the handle 7 of the pulling means 5 in the inner portion can be brought out. The exit slit 8 itself is formed in the longitudinal direction of the seat cover 1 along the substantially center line of the seat cover 1 so as to face the handle 7 arranged in the center of the shape retainer 6, as shown in the figure. It has a length corresponding to the adjustment allowance when it is wound around the transported object C. The exit slits 8 correspond to the position and the number of the handles 7, and if there are two or more handles 7, the exit slits 8 correspond to the positions and the numbers. It may be formed over the entire area 1.

The pulling means 5 itself is usually attached to both ends of the seat cover 1 in the longitudinal direction, but the seat cover 1 itself can correspond to different peripheral lengths of the transported object C. Therefore, at least one of the end portions of the seat cover 1 is provided with a plurality of pulling means 5. For example, as shown in the figure, a plurality of towing means 5 are attached to the end portion of the seat cover 1 at appropriate intervals, and the extra length during use is stored inward, for example, in a folded shape. You can keep it.

Although not shown in the drawings, a stretchable member that can be expanded and contracted, for example, in the middle of the seat cover 1, for example, in the middle portion or in the vicinity of both ends, is made of, for example, a rubber or other material that can be used for preventing load collapse. One or more elastic bands made of the synthetic resin material may be sewn or bonded together so as to be interleaved and connected in parallel. In addition, such a configuration has an advantage that the periphery of the transported article C can be fastened in an appropriate tightened state when the rolled article is mounted on the transported article C. Further, in the seat cover 1, at both ends of the seat cover 1, the fixing means 2 by means of belt-shaped surface fasteners are provided on both inner and outer sides of the seat cover 1 so that either of the overlapped end parts may be the outer part or the inner part. It is also possible to symmetrically form the elongated pull-out slit 8 which is notched so that the pulling means 5 and the handle 7 of the pulling means 5 can be pulled out.

Although not shown, either the seat cover 1 or the seat cover 1 is made of a material having a relatively high hardness such as metal or rigid synthetic resin so as to facilitate the insertion work between the articles C to be transported. At the side edge on the end side of the sheet cover, a temporary insertion piece to be inserted and inserted between the stacked articles C is projected, or one of the longitudinal edges of the seat cover 1 is provided with rubber. It is also possible to insert a temporary fixing insertion tool made of covered metal or the like and inserted between the stacked articles C, and having a substantially L-shaped cross section to be inserted. In addition, both ends of the sheet cover 1 or the front and back surfaces on either side of the sheet cover 1 are coated with rubber or the like so as to prevent slipping after insertion, or the sheet cover 1 is prevented from slipping. 1 gradually becomes narrower as it reaches the edge at one of the ends in the longitudinal direction, and the surface is coated with rubber to prevent slippage, so that it can be inserted between the objects C to be transported. Alternatively, a temporary fixing insertion portion to be inserted may be formed. In either case, one of the longitudinal ends of the seat cover 1 is inserted between the objects to be conveyed C to be temporarily fixed, and after the seat cover 1 has been wound, the seat cover 1 is removed and the both ends of the seat cover 1 are separated from each other. It is needless to say that the structure, shape, etc. are not limited since they can be appropriately connected and fixed.

Next, to explain an example of use of the device of the present invention, as shown in FIG. 3, in the seat cover 1 folded by the folding biasing means 3, the shape retaining material in the traction means 5 is used. The outer peripheral end portion which is made rigid by enclosing 6 is forcibly inserted and inserted between the conveyed articles C (see FIG. 3 (A)). While gradually expanding the seat cover 1 that has been folded by the urging force urging means 3 from one end, the seat cover 1 that has been temporarily fixed by the insertion is wound around the transported object C (see FIG. 3 (B)). ), The other end portion side where the exit slit 8 is formed is overlapped on the outer surface of the one end portion side, and the handle 7 on the one end side is passed through the exit slit 8 to the outside of the seat cover 1. Insert it in one direction and let it out, and tighten it (see FIG. 3 (C)). Then, the grips 7 of the pulling means 5 at both ends of the seat cover 1 are pulled to firmly bring the seat cover 1 into close contact with the periphery of the conveyed object C, and the overlapping both ends are connected and fixed by the fixing means 2 ( See FIG. 3D).

When the load collapse prevention device for transported goods of the present invention is not used, the seat biasing means 3 causes the seat cover 1 to form one roll from one end or two rolls in parallel from each end. It can be rolled into a swirl state automatically, and the whole is automatically compacted, transported and stored. The winding state is automatically performed by the winding urging means 3. However, when winding around the conveyed object C, either the inner side surface or the outer side surface of the conveyed object C is the peripheral surface of the conveyed object C. However, by winding the outer side surface of the rolled-in state against the peripheral surface of the transported object C (see FIG. 1) to rewind, the roll mounting work can be performed more smoothly. You can

[0028]

[Effect of device]

 The present invention is configured as described above, and therefore, it is possible to fix the pallets for loading and unloading and the like by fixing the circumferences of various objects C stacked in a stacked manner on the loading platform P such as a trolley. It is possible to bind and fix the cargo, and to prevent the cargo C from being unloaded when it is loaded / unloaded on / from the truck bed and stored in the warehouse. Moreover, in the winding fixing work for the conveyed object C, one end is temporarily fixed to the conveyed object C and the seat cover 1 held by the urging force urging means 3 is gradually unfolded while the conveyed object C is fixed. Since the surroundings are fixed in a wrapping manner, the other end of the seat cover 1 can be left loose and loosely released as in the conventional case, so that the seat cover 1 can be caught, wound, or clinging to the worker's feet. There is no defect, and only one worker can smoothly and easily carry out the roll mounting work. Further, when the seat cover 1 fixed to the transported object C is removed, the seat cover 1 can be immediately put into a compact state, and the work efficiency at the time of removal and storage is improved. Further, when the seat cover 1 is stored, it is not necessary to tie the entire seat cover 1 with a string or the like, and wrinkles, slacks, and creases do not occur.

Further, when unnecessary, the fixing means 2 can be easily removed from the transported article C by releasing and separating the fixing means 2, and since it can be repeatedly used, there is no waste. It is possible to solve various pollution problems caused by discarding the sheets of the, and when it is not needed, it can be stored compactly, can be easily carried, and can be quickly used for loading, unloading and carrying work.

Since the winding biasing means 3 is composed of a spring member formed by a spiral spring, during the rolling operation of the entire seat cover 1, it may be twisted or slipped in and rolled in. Instead, it is possible to smoothly roll up the rolling action force due to a constant lateral pressure of the spiral spring and a predetermined rolling direction, and the fabrication itself can be configured easily and at low cost.

Further, at both ends of the seat cover 1, a drafting means 5 for superposing the end portions of the seat cover 1 on each other is attached, and the pulling means 5 is made substantially orthogonal to the rolling direction of the seat cover 1. Since the rigid shape-retaining material 6 fixed to the seat cover 1 and the handle 7 arranged on the seat cover 1 near the shape-retaining material 6 are provided, the fixed portion as a whole is not distorted. You can move smoothly. Moreover, when tightening and pulling the seat cover 1 with respect to the transported object C, the pulling amount can be freely adjusted by the pulling means 5 between the overlapping end portions of the seat cover 1, and wrinkles and slack are generated in the entire sheet cover 1. Instead, it is possible to bind various cargos C stacked in a stack and prevent the cargo from slipping.

Further, when both ends of the seat cover 1 are towed by the tow means 5 and are overlapped and connected to each other, the handle 7 of the tow means 5 of the inner part is attached to the outer part of the end part of the seat cover 1 to be overlapped. Since a slender outward slit 8 is formed that is notched so that it can go out, the inner handles 7 at the end portions where the seat cover 1 is overlapped can go out through the outward slit 8 and the pulling work between the end portions is extremely easy. In this way, the tightening of the wrapping around the load C can be made firm.
