Description

  The present invention relates to a pallet discriminator for identifying a pallet on which a transported object transported by a forklift or the like is mounted, and a pallet provided with the pallet discriminator.

  When a large number of loads are loaded on a truck or the like, it takes time and labor to load the loads, so a large number of loads are loaded together on a pallet and loaded together with the pallet. Further, as this kind of pallet, in order to facilitate loading work by a forklift, a pallet having an insertion hole into which a fork of a forklift can be inserted is often used.

  Furthermore, since many pallets are often used, there are pallets in which individual pallets can be identified by attaching wireless identification tags such as ID tags to the respective pallets. As such a pallet, conventionally, there is a pallet in which a through-hole penetrating two side surfaces provided with a fork insertion port is provided, and a non-contact type IC tag is provided inside the through-hole (for example, , See Patent Document 1).

JP 2005-119670 A

  However, in the pallet disclosed in Patent Document 1, a wireless identification tag (non-contact type IC tag) is attached to a through hole formed between fork insertion ports. For this reason, since it is necessary to form a through hole for attaching the wireless identification tag, it takes much time. In particular, when considering attaching a new wireless identification tag to an existing pallet in which no through hole is formed between the fork insertion ports, a new through hole must be formed in the pallet. , That effort will be very large.

  Further, when attaching the wireless identification tag to the pallet, it is conceivable to attach the wireless identification tag directly inside the insertion hole serving as the fork insertion port. However, the fork of the forklift is inserted into the insertion hole when the pallet is conveyed. For this reason, when the wireless identification tag is attached to the insertion hole, there is a problem that the wireless identification tag may be damaged by the fork of the forklift.

  Accordingly, an object of the present invention is to reduce the labor required for attaching a wireless identification tag to a pallet and prevent damage to the wireless identification tag due to contact with a fork of a forklift. It is to provide an identifier and a pallet.

  A pallet discriminator according to the present invention that has solved the above-mentioned problems is a pallet discriminator including a radio identification tag that is formed with an insertion hole into which a fork in a forklift is inserted and is attached to the pallet that is lifted by the forklift. A fork interference prevention structure for preventing interference between the identification tag and the fork in the forklift is formed.

  In the pallet discriminator according to the present invention, since the radio identification tag is provided in the fork pocket, it is not necessary to form a through hole or the like for providing the radio identification tag in the pallet. Therefore, when attaching the wireless identification tag to the pallet, it is possible to reduce the labor required for the attachment. Further, a fork interference prevention structure for preventing interference between the wireless identification tag and the fork in the forklift is formed. For this reason, damage to the wireless identification tag due to contact with the fork of the forklift can be prevented.

  Here, the fork interference prevention structure includes a tag holder that covers the wireless identification tag attached to the pallet, and the tag holder protrudes from the inner surface of the pallet and is attached to the pallet. It is possible to form an inclination that is displaced inward of the tag holder as the distance increases.

  In this manner, by providing the tag holder that covers the wireless identification tag attached to the pallet, damage to the wireless identification tag can be prevented. Furthermore, the tag holder protrudes from the inner side surface of the pallet and is attached to the pallet, and the side surface of the tag holder is formed with an inclination that is displaced inward of the tag holder as the distance from the inner side surface of the pallet increases. For this reason, the fork moving toward the tag holder can be guided away from the tag holder. Therefore, since the force transmitted from the fork to the tag holder can be reduced, the tag holder can be prevented from being damaged, and further, the wireless identification tag stored in the tag holder can be suitably prevented from being damaged.

  Further, the inclination may be formed on a relative surface facing the fork insertion direction in the forklift in the tag holder.

  As described above, the inclination is formed on the relative surface facing the fork in the forklift in the tag holder in the insertion direction, so that the tag holder can be protected with respect to the moving direction of the fork that moves more.

  Furthermore, the pallet includes a top plate and a bottom plate, and includes an inner girder and an outer girder that support the top plate by the bottom plate, an inner side surface is formed on the inner girder, and a tag holder is fixed to the inner side surface. Can be.

  As described above, since the tag holder is provided in the inner beam, it is possible to prevent the wireless identification tag and the tag holder from getting in the way when a load or the like is mounted on the pallet.

  In addition, a through hole for penetrating the tag holder is formed in the top plate of the pallet, the tag holder is attached to the tag holder holding portion, the tag holder holding portion holds the tag holder through the through hole, and the top of the pallet. A flange portion locked to a through hole formed in the plate can be provided. By setting it as such a structure, a tag holder can be hold | maintained easily.

  Further, as a fork interference prevention structure, a tag accommodating portion is formed on the inner side surface of the pallet, a radio identification tag is accommodated in the tag accommodating portion, a lid member is attached to the tag accommodating portion so as to cover the radio identification tag, and the lid member Can be arranged at a position flush with the inner surface of the pallet or at a position recessed from the surface. With such a configuration, contact between the wireless identification tag and the fork can be prevented, and protection can be provided by the lid member.

  On the other hand, the tag holder concerning the present invention which solved the above-mentioned subject is a tag holder used for the above-mentioned pallet discriminator. Moreover, the pallet which concerns on this invention which solved the said subject is a pallet provided with said discriminator for pallets.

  According to the pallet discriminator and the pallet vehicle body front structure according to the present invention, when the radio identification tag is attached to the pallet, the labor required for the attachment is reduced, and the radio identification tag is brought into contact with the fork of the forklift. Can prevent damage.

In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. For the convenience of illustration, the dimensional ratios in the drawings do not necessarily match those described.

[First Embodiment]
First, a first embodiment of the present invention will be described. 1A is a perspective view of a pallet to which a pallet discriminator according to the first embodiment of the present invention is attached, FIG. 1B is a partially enlarged view thereof, and FIG. 2 is a tag holder in the pallet discriminator. FIG.

  As shown in FIG. 1A, the pallet 1 includes an upper surface deck 11 that is a top plate and a lower surface deck 12 that is a bottom plate. An inner girder 13 and an outer girder 14 are provided between the upper surface deck 11 and the lower surface deck 12. One inner girder 13 is arranged at the center of the pallet 1, and two outer girders 14 are arranged at the edge of the pallet 1. Both the inner girder 13 and the outer girder 14 are long members and are arranged substantially parallel to each other, and the upper deck 11 is supported by the lower deck 12 by the inner girder 13 and the outer girder 14.

  Further, fork pockets 15 and 16 are formed between the inner beam 13 and the outer beam 14 as insertion holes into which the forks of the forklifts are respectively inserted. The fork pockets 15 and 16 are formed so as to pass through between one end surface of the pallet 1 and the other end surface opposite to the one end surface, and an opening on one end surface side becomes an insertion port for a fork of a forklift.

  Further, a pallet discriminator M1 is provided on the inner side of the inner girder 13 on the fork pocket 15 side. The pallet classifier M1 includes a tag holder 2, a wireless identification tag 3, and a hanging member 4. The tag holder 2 is integrated with the hanging member 4 as shown in FIGS. Is formed. Further, the wireless identification tag 3 is stored in the tag holder 2.

  The tag holder 2 includes an attachment surface 21 attached to the inner beam 13 and a front side surface 22 that faces the attachment surface 21 and is exposed inside the pallet 1. Further, the tag holder 2 has a three-dimensional shape including a front side surface 23, a back side surface 24, and a lower side surface 25 between the attachment surface 21 and the front side surface 22.

  The tag holder 2 is attached to the pallet 1 so as to protrude from the inner surface of the inner beam 13 in the pallet 1. For this reason, the tag holder 2 can be attached to the inner beam 13 without forming a recess or the like for storing the tag holder 2 in the inner beam 13 of the pallet 1. The tag holder 2 is made of synthetic resin.

  Further, the front side surface, which is a relative surface facing the fork insertion direction in the tag holder 2, is inclined. The inclination on the front side surface 23 is an inclination that is displaced inward of the tag holder 2 as the distance from the inner side surface of the inner beam 13 in the pallet 1 increases. For this reason, the inclination attached | subjected to the front side surface 23 will be displaced in the direction away from the inner girder 13, so that it is far from the insertion port of the fork of a forklift.

  Similarly, the rear side surface 24 and the lower side surface 25 are also inclined so as to be displaced inward of the tag holder 2 as the distance from the inner surface of the inner beam 13 in the pallet 1 increases. For this reason, the area of the mounting surface 21 in the tag holder 2 is larger than the area of the front side surface 22. Further, the upper side surface of the tag holder 2 is integrally fixed to the suspension member 4.

  A tag storage recess 26 is formed on the mounting surface 21 of the tag holder 2, and the wireless identification tag 3 is stored in the tag storage recess 26. By storing the wireless identification tag 3 in the tag storage recess 26 in the tag holder 2, the wireless identification tag 3 is protected by the tag holder 2. By storing the wireless identification tag 3 in the tag holder 2, a fork interference preventing structure for preventing interference between the wireless identification tag 3 and the fork in the forklift is formed.

  The wireless identification tag 3 is configured to be able to transmit and receive data to and from an external reading device or writing device using a radio wave such as a microwave. In the wireless identification tag 3, memory areas of a system area and a user area are set. In the system area, the individual number of the wireless identification tag 3 is managed, and predetermined initial information is written when the tag is manufactured. In the user area, a company code, a loaded product code, a manufacturing date, a quantity for each loaded product, and a delivery destination code are read or rewritten.

  The suspension member 4 includes a holding plate 41 and an attachment member 42, and holds the tag holder 2 suspended from the upper side of the upper surface deck 11 in the pallet 1. As shown in FIG. 1 (b), the top deck 11 in the pallet 1 is formed with a through hole 17 that allows the tag holder 2 to pass therethrough, and the outer surface of the through hole 17 has substantially the same outer shape as the holding plate 41. A fitting recess (not shown) having a shape is formed. The suspension member 4 forms the tag holder holding part of the present invention, and the holding plate 41 locks the flange part.

  The holding plate 41 in the suspending member 4 is fitted in the fitting recess and held in the fitting recess in the top deck 11, and suspends the tag holder 2 attached to the attachment member 42. The fitting recess is formed along the inner surface of the inner beam 13, and the attachment surface 21 of the tag holder 2 suspended by the suspension member 4 is disposed in contact with the inner surface of the inner beam 13. Has been. For this reason, the wireless identification tag 3 stored in the tag holder 2 is sealed by the inner beam 13 and the tag holder 2.

  Next, the operation of the pallet classifier according to this embodiment will be described. The pallet discriminator M1 according to this embodiment includes a wireless identification tag 3 attached to the pallet 1, and the wireless identification tag 3 performs wireless communication with an external reader or the like, whereby the pallet 1 management can be performed. In addition, since the wireless identification tag 3 is attached to the inner surface of the inner beam 13, a reader or the like is arranged on the side when the forklift is transporting to perform wireless communication with the wireless identification tag 3. When performing, wireless communication with excellent sensitivity can be performed.

  Here, since the wireless identification tag 3 is provided in the fork pocket 15, it is not necessary to form a through hole or the like for providing the wireless identification tag 3 in the inner beam 13 or the like. Therefore, when attaching the wireless identification tag 3 to the pallet 1, it is possible to reduce the labor required for the attachment. In particular, when adding a wireless identification tag to an existing pallet and attaching it, the effect of reducing labor is increased.

  Further, the inner side surface of the inner beam 13 to which the wireless identification tag 3 is attached in the pallet classifier M1 is located in the fork pocket into which the fork of the forklift is inserted. The width of the fork pocket is often set to be slightly wider than the fork, and the fork may contact the pallet discriminator M1 by moving the fork in the front-rear direction or the vertical direction.

  If the fork contacts the pallet classifier M1, the radio identification tag 3 will be damaged. Therefore, by storing the wireless identification tag 3 in the tag holder 2, the wireless identification tag 3 is protected by the tag holder 2. By protecting the wireless identification tag 3 with the tag holder 2, some damage to the wireless identification tag 3 can be prevented.

  However, if the fork of the forklift strongly collides with the tag holder 2 and the tag holder 2 itself is damaged, there is a concern that the wireless identification tag 3 may be damaged. In order to prevent such damage to the tag holder 2, the side surfaces 23 to 25 of the tag holder 2 in the pallet discriminator M1 according to this embodiment are arranged so as to move away from the inner side surface of the inner girder 13 in the pallet 1. An inclination that is displaced in the direction is attached.

  Now, the operation of the tag holder 2 according to the present embodiment will be described by comparing the tag holder not provided with such an inclination with the tag holder 2 according to the present embodiment. As shown in FIG. 3A, when the tag holder 20 having no inclined side surface is attached to the inner beam 13, when the fork T of the forklift is inserted into the fork pocket in the pallet 1, It is conceivable to contact the tag holder 20.

  At this time, since the side surface of the tag holder 20 is not inclined, the fork T inserted into and contacting the insertion portion of the pallet 1 pushes the tag holder 20 in the traveling direction as it is. As a result, a large force is applied to the tag holder 20 from the fork T, and there is a high possibility that the tag holder 20 and the wireless identification tag 3 stored in the tag holder 20 will be damaged.

  In this regard, the front side surface 23 of the tag holder 2 according to the present embodiment is provided with an inclination that is displaced inward of the tag holder 2 as the distance from the inner side surface of the inner beam 13 in the pallet 1 increases. Therefore, as shown in FIG. 3B, even if the fork T is inserted into the fork pocket and comes into contact with the tag holder 2, the fork T is guided away from the tag holder 2 by the inclination formed in the tag holder 2. be able to. Therefore, since the force transmitted from the fork T to the tag holder 2 can be reduced, the tag holder 2 can be prevented from being damaged, and further, the wireless identification tag 3 stored in the tag holder 2 can be prevented from being damaged.

  FIG. 3 illustrates the relationship between the fork T and the tag holder 2 when the fork T moves in the front-rear direction, but the same applies when the fork T moves up and down. Since the lower side surface 25 of the tag holder 2 is also inclined so as to move away from the inner side surface of the inner beam 13 in the pallet 1, the fork T moves up and down when the fork T moves up and down. It is possible to guide in a direction away from 2. Therefore, the tag holder 2 can be prevented from being damaged, and further, the wireless identification tag 3 stored in the tag holder 2 can be prevented from being damaged.
