[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plastic pallet for a forklift used for storing and transporting luggage.
[0002]
[Prior art]
Conventionally, plastic pallets for storing and transporting luggage are moved by placing the luggage and inserting the fork of the forklift into the fork insertion port, and the luggage is placed directly on the pallet. In some cases, there is a case where a rug is laid and placed on the rug to prevent dirt and damage on the luggage. For example, as shown in FIG. 9, in order to store and transport the lid of an aluminum can, a large number of disk-shaped lids 1 are arranged in close contact with each other and wrapped in wrapping paper to form a rod-like body 2 stacked on a pallet 3. In order to protect the lid 1 of the aluminum can, the cardboard paper 4 is laid on the pallet 3 as a rug and placed thereon.
[0003]
The cardboard paper 4 is fixed to the pallet 3 with an adhesive tape 5 in order to prevent the cardboard paper itself from being displaced and to prevent the cardboard paper from collapsing the load. As shown in the drawing, one end of the adhesive tape 5 is attached to the upper surface of the cardboard paper 4 and the other end is attached to the lower surface of the upper deck board 7 in the fork insertion port 6 of the pallet 3.
[0004]
[Problems to be solved by the invention]
In the conventional plastic pallet, reinforcing ribs are formed on the lower surface of the upper deck board 7 in parallel and orthogonal directions or oblique directions with respect to the side surface of the pallet in order to increase the strength. Therefore, although the upper surface of the upper deck board is flat, the lower surface has a rib structure, and no consideration is given to the structure for adhering the adhesive tape 5. For this reason, the pressure-sensitive adhesive tape 5 is stuck to the lower surface of the reinforcing ribs with a wide interval, and there is a problem that a sufficient sticking force cannot be obtained because the sticking area is small and the tape is easily peeled off. Further, since the adhesive tape 5 is attached to the surface of the forklift that comes into contact with the fork, there is a problem that the fork comes into contact with and peels off when the fork is taken in and out.
[0005]
Further, when stacking pallets, manual operations such as aligning the end surfaces of the pallets and changing the direction of the fork insertion port to facilitate the insertion of the forks in the next use are performed. Such work is done by inserting a hand into the fork insertion slot and placing a hand on the rib or support provided on the inner surface of the deck board, but in the case of the two-way insertion type, the fork insertion slot is in one direction. Because there is no, you can not put your hand. For this reason, a handle portion is provided on the side plate portions of the end girders located at both ends of the plurality of girders arranged along the fork insertion direction so that the two-way insertion type can also be handled. A pallet has been proposed (JP-A-8-133286). Although the workability and operability are improved, the pallet has the following problems.
[0006]
Since the handle portion is formed by forming a concave shape opening on the surface of the side plate portion, it can be lifted or dragged by inserting a hand, but the side plate portion is in contact with the wall surface In addition, since the hand cannot be inserted, for example, when the side plate portions are in contact with each other, the handle portion cannot be used. Further, even a pallet having a through-hole formed on the deck board surface has problems such as a small through-hole and a finger not being inserted, and even if a finger is inserted, the contact is poor and the work cannot be performed safely.
[0007]
Therefore, the present invention solves the above-mentioned problems, can sufficiently hold the adhesive force of the adhesive tape, and can attach a hand from the top surface of the deck board and the tape attaching portion of the adhesive tape that the fork does not contact A plastic pallet provided with holes is provided.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows. That is, in the plastic pallet according to claim 1 of the present invention, the upper deck board is composed of the top plate and the reinforcing rib provided on the lower surface of the top plate, and is at least the lower surface of the upper deck board facing the fork insertion port. A tape adhering portion for adhering an adhesive tape is provided between the deck board edge and the lateral rib parallel to the edge. The plastic pallet according to claim 2 is characterized in that the sticking surface of the tape sticking portion is formed in a horizontal plane substantially parallel to the top plate of the upper deck board. Further, the plastic pallet according to claim 3 is such that the sticking surface of the tape sticking portion is an inclined surface having the same or a small angle as the inclined surface of the upper deck board edge with respect to the top plate of the upper deck board. It is formed. The plastic pallet according to claim 4 is characterized in that the tape adhering portion is formed by a rib. The plastic pallet according to claim 5 is a two-way pallet in which a fork can be inserted from two directions having an end column part parallel to a side surface in one direction and an intermediate column part provided in the middle. In addition to providing a tape adhering portion between at least the edge of the upper deck board facing the fork insertion slot and a lateral rib parallel to the edge, a handle hole is provided in the upper surface of the upper deck board. Features. The plastic pallet according to claim 6 is characterized in that the handle hole is formed by a through hole penetrating the end column portion.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments illustrating the present invention will be described in detail below. FIG. 1 shows a two-way type pallet in which an upper deck board 10 and a lower deck board 11 are connected by a support column 13 at an end parallel to a side surface in one direction and an intermediate support column 15 provided in the middle. Thus, the space surrounded by the upper and lower deck boards 10, 11, the column part 13 and the intermediate column part 15 is used as a fork insertion port 17. The pallet is formed by abutting and welding an upper part and a lower part, which are divided and formed in advance, at the support part, and the support part has a hollow structure.
[0010]
A tape adhering portion 19, which is a feature of the present invention, is provided in the vicinity of the intermediate strut portion 15 of the upper deck board 10 and the lower deck board 11, and further, the upper and lower deck board portions of the end strut portion 13 are provided. A handle hole 20 is provided. The upper deck board 10 and the lower deck board 11 of the pallet are composed of a top plate 21, a vertical rib 23 provided on the lower surface of the top plate 21, parallel to the fork insertion direction, and a horizontal rib 25 perpendicular to the fork insertion direction. Become. Of the horizontal ribs 25, the horizontal ribs 25 a located at the edge of the top plate 21 are formed to be lower in height than the horizontal ribs 25 inside thereof. On the other hand, the vertical ribs 23 are formed with a narrow space between the horizontal ribs 25a and the horizontal ribs 25 inside the horizontal ribs 25a, and are inclined so as to have the same height as the horizontal ribs (see FIG. 3). ). In this way, the fork can be easily inserted by making the end edge of the deck board an inclined surface.
[0011]
The tape adhering portion 19 is a portion surrounded by the intermediate strut portion 15, the vertical ribs 23, and the horizontal ribs 25, and the top plate 21 has the same thickness as the edge ribs 25a, and the tape is peeled off. It is formed by perforating a plurality of small holes 27 for facilitating the process. And the sticking surface 28 of a tape sticking part is formed in the horizontal surface substantially parallel to the top plate of an upper deck board. The width dimension in the front end direction of the tape adhering portion 19 is wider than the width dimension of the pressure-sensitive adhesive tape to be used, but is preferably narrower than the width dimension of the fork. As described above, since the vertical ribs 23 are removed and the sticking surface 28 of the tape sticking portion can be directly stuck, the sticking area can be increased and the contact of the fork can be prevented. Even in the carrying work by the forklift, the fork is guided and inserted by the inclined surface of the vertical rib 23, so that it does not come into contact with the adhesive tape, and therefore the adhesive tape is not peeled off. In addition, although the said tape sticking part 19 was made into the thickness same as the height of the horizontal rib 25a of an edge, the horizontal rib 25a of the said edge may be removed and it may be set as the thickness of the top plate 21. FIG.
[0012]
Subsequently, 2nd Embodiment of a tape sticking part is described based on FIG.4 and FIG.5. The tape adhering portion 29 is a portion surrounded by the intermediate strut portion 15, the vertical ribs 23, and the horizontal ribs 25, and is provided with grid-like ribs 30 on the lower surface of the top plate 21 from which the horizontal ribs 25a at the edges are removed. Thus, the top plate 21 inside the grid-like rib 30 is formed by penetrating through the through-hole 31 and forming a sticking surface 33 with the tip end face of the grid-like rib 30 inclined. As described above, when the horizontal ribs 25 a at the edge are removed and the grid-like ribs 30 are provided on the top plate 21, the sticking surface 33 of the grid-like ribs 30 is larger than the inclined surface at the end of the vertical ribs 23. Thus, the fork contacts the longitudinal rib 23 and does not directly contact the adhesive tape, so that the adhesive tape is prevented from peeling off.
[0013]
If the sticking surface 33 is formed on the inclined surface having the same or a small angle with respect to the top plate 21 of the upper deck board as opposed to the above, Since the rib 25a is formed lower than the lateral rib 25 on the inner side, the fork is guided in contact with the inclined surface of the vertical rib 23 and does not contact the adhesive tape. When the grid-like ribs 30 are formed to be thicker than the thickness of the top plate 21, the angle of the sticking surface 33 is set to be larger than the inclined surface of the deck board edge (the inclined surface of the vertical rib 23). What is necessary is just to form small.
[0014]
FIG. 6 shows a third embodiment of the tape adhering portion, and the tape adhering portion 39 is obtained by replacing the lattice-like ribs 30 in the second embodiment with the parallel ribs 35 and omitting the through holes 31. is there. In addition to the configuration in which the front end surface of the parallel rib 35 is an inclined attachment surface 37, the angle of the attachment surface 37 can be arbitrarily changed, or the thickness of the top plate can be increased to provide the parallel rib 35. The same as in the second embodiment. Also in this embodiment, when the fork is inserted, the fork comes into contact with the vertical rib 23, so that the adhesive tape is not peeled off. In addition, although the said tape sticking part was provided adjacent to the intermediate | middle support | pillar part 15 in the said embodiment, if the edge part of the deck board which faces a fork insertion port, the position will not be limited. Absent. Moreover, it is possible to combine the said embodiment suitably.
[0015]
7 and 8 show the configuration of the handle hole 20. The handle hole 20 penetrates from the top plate 21 of the upper deck board 10 to the lower deck board 11 at an arbitrary position of the end column part 13, and is provided with a planar rectangular through hole 20a. A protrusion 20b is provided on the inner surface edge. A pallet can be operated by inserting a hand into the through-hole 20a, and a force can be easily applied and securely gripped by engaging a finger with the protruding portion 20b. The through-hole 20a constituting the handle hole 20 is not limited to a rectangular shape as long as it can be inserted by a hand, and may be an elliptical shape. Further, the size of the protruding portion 20b can be determined as appropriate.
[0016]
The protruding portion 20b can be omitted, and the inner surface straight through hole 20a may be used. Moreover, if the said handle hole 20 is the structure opened to the upper deck board 10, it will not necessarily be a through-hole penetrating the edge part support | pillar part 13 like embodiment, but the upper deck board located in the fork insertion port 17 It may be provided at 10 positions. In this case, the lower surface of the handle hole 20 opens to the fork insertion port.
[0017]
【The invention's effect】
Since the plastic pallet according to the present invention is provided with the tape adhering portion on the inner surface of the deck board, not only can the adhesive force of the adhesive tape be sufficiently retained, but also the adhesive tape is inadvertently peeled off without contact with the fork.
