Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a synthetic resin carrying container used for carrying articles and the like.

When the transportation container containing articles (work) is placed on the pallet for transportation, if the transportation container jumps, there is a risk that the articles may fall from the transportation container or the transportation container may fall from the pallet. there were. Therefore, in order to prevent the transport container from jumping during transportation, various methods have conventionally been adopted. For example, a method of binding the transport container to the pallet using a band, or a method of fixing the transport container to the pallet using a bolt and a nut is adopted.
Moreover, in the previous application (Patent Document 1), the applicant has proposed a tray (carrier for transportation) in which a locking piece for locking to a pallet protrudes from the lower surface.

JP, 2013-227060, A

If the carrying container proposed by the applicant in the earlier application (Patent Document 1) is implemented, the carrying container is fixed to the pallet simply by locking the locking piece projecting from the lower surface of the carrying container to the pallet. Therefore, it takes less time than the method using a band, a bolt and a nut.
However, there are cases in which the shape of the carrying container is limited and the locking piece can not be provided on the lower surface of the carrying container. In such a case, since the transport container must be fixed to the pallet using a band, a bolt and a nut as in the prior art, the working efficiency for preventing the transport container from jumping is deteriorated.

  Then, this invention is created in order to solve said problem, Comprising: It aims at providing the conveyance container which can improve the working efficiency for making a conveyance container not jump. I assume.

  In order to achieve the above-mentioned object, the transport container of the present invention is a transport container made of synthetic resin placed on a pallet, and the projection projecting on the side of the pallet on which the transport container is mounted A columnar member having a portion is erected, and includes a transportable container main body, and an overhang portion protruding from the transport container main body in the vicinity of the columnar member. The overhanging portion is provided with a blocking portion for preventing the transport container from jumping more than at the time of the collision by colliding with the projection from below when the transport container placed on the pallet is jumping. ing. The above is the first feature.

Even if the carrying container jumps when the carrying container is placed on the pallet and carried, even if the carrying container jumps, the blocking portion provided in the overhanging portion protruding from the carrying container main body in the vicinity of the pillar member is the pillar member. By colliding with the projection from below, it is possible to prevent the carrying container from jumping up more than at the time of the collision.
That is, it is only necessary to place the transport container on the pallet so that the blocking portion provided in the overhang portion collides with the projection of the columnar member from below when the transport container jumps, as in the prior art, There is no need to bind the carrying container to the pallet with a band to prevent jumping of the carrying container or to fix the carrying container to the pallet with bolts and nuts.
Therefore, the work efficiency for preventing the shipping container from jumping can be improved.
In addition, since the above-mentioned band, bolt and nut are unnecessary, the cost for preventing the shipping container from jumping can be reduced.

  Further, in the transport container according to the present invention, in the first feature described above, when the transport container placed on the pallet moves in the horizontal direction, the projecting portion abuts on the circumferential surface of the columnar member. Thus, the second feature of the present invention is that a restricting portion that restricts the movement of the transport container in the horizontal direction is provided.

Even when the transport container is moved in the horizontal direction when the transport container is placed on the pallet and transported, the restricting portion provided in the overhang portion protruding from the transport container main body in the vicinity of the columnar member is By contacting the circumferential surface of the columnar member, the horizontal movement of the transport container can be restricted.
In other words, simply by placing the carrying container on the pallet, the horizontal movement of the carrying container can be regulated, so the band can be used to restrict the horizontal movement of the carrying container. There is no need to bind the transport container to the pallet or to fix the transport container to the pallet with bolts and nuts.
Therefore, it is possible to improve work efficiency for preventing the transport container from moving in the horizontal direction.
Moreover, since the above-mentioned band, bolt and nut are unnecessary, the cost for preventing the transport container from moving in the horizontal direction can be reduced.

By the way, when placing the transport container on the pallet or taking out the transport container from the pallet due to the variation in the projection length of the protrusion of the columnar member or the variation in the outer shape of the transport container, or the like, It is conceivable that the workability is deteriorated such that the tip of the blocking portion provided on the portion or the tip of the regulating portion is caught by the projecting portion, and the placement operation is retried or the removal operation is retried.
However, since one of the third features of the transport container of the present invention is that the overhanging portion is formed in a flexible bowl shape, when the transport container is placed on a pallet, or Even when the end of the blocking portion provided in the overhanging portion is caught on the projecting portion when taking it out of the pallet, the overhanging portion is bent and deformed, and the tip of the blocking portion climbs over the projecting portion. There is no risk of getting worse.

In addition, when mounting the transport container on the pallet or when removing the transport container from the pallet due to variations in the projection length of the projecting portion of the columnar member or variations in the external shape of the transport container, or the like, It is conceivable that workability is deteriorated such that the tip end of the regulating portion provided in the portion is caught by the columnar member, and the placing operation is retried or the taking-out operation is retried.
However, one of the fourth features of the carrying container of the present invention is that the overhanging portion is formed in a flexible bowl shape, and therefore, when the carrying container is placed on a pallet, or When taking out from the pallet, even if the end of the restricting portion provided in the overhanging portion is stuck to the columnar member, the overhanging portion is bent and deformed, and the end of the restricting portion passes through the jammed portion Therefore, there is no risk of worsening the workability.

Furthermore, the carrying container of the present invention has, as one of the third features, a notched portion formed by cutting out a shape surrounding a predetermined range of the circumferential surface of the columnar member at the tip of the overhanging portion It also has a feature that a blocking portion is provided in the notch portion.
In other words, it is realized by devising the shape of the container for transportation by providing the notched part formed in the shape surrounding the predetermined range of the peripheral surface of the columnar member at the tip of the overhanging part and providing the blocking part in the notched part. The relatively simple structure that can be made can prevent the jumping of the carrying container.
Therefore, it is also possible to reduce the cost of preventing the shipping container from jumping, as it is not necessary to manufacture the blocking portion separately and attach it to the shipping container.

Furthermore, the carrying container of the present invention has, as one of the fourth features, a notched portion formed by cutting out a shape surrounding a predetermined range of the circumferential surface of the columnar member at the tip of the projecting portion It also has a feature that a restricting portion is provided in the notch portion.
In other words, it is realized by devising the shape of the container for transportation by providing a notch formed in the shape of a notch surrounding the predetermined range of the circumferential surface of the columnar member at the tip of the overhang and providing a restriction in the notch. The relatively simple structure that can be made can restrict the horizontal movement of the transport container.
Therefore, since it is not necessary to manufacture a control part separately and to attach to a conveyance container, the cost for keeping a conveyance container from moving horizontally can also be reduced.

  By implementing the transport container of the present invention, it is possible to provide a transport container which can improve the working efficiency for preventing the transport container from jumping.

In this embodiment, the transport container 1 is molded by vacuum molding using a synthetic resin raw material such as polypropylene, polyethylene, or ABS resin. Moreover, since each flange part 12-15 is thinly formed, it has flexibility and can be deformed.

FIG. 4 is a perspective view showing the transport container 1 shown in FIG. 1 placed on the pallet 40. As shown in FIG. FIG. 5 is a perspective view showing a state in which the transport container shown in FIG. 1 is placed on the pallet 40 and each column 52 of the pallet 40 falls. 6 is a cross-sectional view taken along the line AA of FIG. 4, and FIG. 7 is a cross-sectional view of the periphery of the support column 50. As shown in FIG. FIG. 8 is a cross-sectional view taken along line B-B in FIG.
As shown in FIG. 4, the pallet 40 on which the transport container 1 is placed is formed in a plate shape having a rectangular shape in a plan view and a large thickness. Cavities 42, 42 are formed inward from the side surface 41 along the longitudinal direction of the pallet 40, and are formed inward from the side surface (not shown) opposite to the side surface 41, 42 (not shown) are formed. Each hollow portion 42 is used to insert a fork when performing an operation such as lifting and lowering the pallet 40 by means of a fork-like transport means such as a forklift.

  At the four corners of the pallet 40, columns 50 are erected. Each column 50 includes a holding member 51, a column 52 held by the holding member 51, and a head 53 formed at the tip of the column 52. As shown in FIG. 7, each holding member 51 is formed into a hollow prism having a substantially U-shaped cross section, and one of the four side surfaces is an opening surface. Then, prismatic columns 52 are respectively held in the internal space of the holding members 51. Further, as shown in FIG. 4, the holding members 51 erected at both end corner portions of the third flange portion 14 are arranged such that the opening faces face each other. Further, the holding members 51 erected at both end corner portions of the fourth flange portion 15 are also arranged such that the opening faces face each other.

As shown in FIG. 5, among the side surfaces of each pillar 52 provided at the corner portions of both ends of the fourth flange portion 15, the side surface facing each pillar 52 provided at the corner portions of both ends of the third flange portion 14. In each case, slits 54 are formed along the longitudinal direction. Further, although not shown in FIG. 5, among the side surfaces of the columns 52 provided at the corners of both ends of the third flange portion 14, the columns 52 provided at the corners of both ends of the fourth flange portion 15 and Slits 54 are also formed on the opposite side surfaces along the longitudinal direction.
As shown in FIG. 6, in each holding member 51, the lock pin 60 is respectively inserted in the slit 54 through the side surface 51a. The head 61 of each lock pin 60 projects from the side surface 51 a of the holding member 51. Each pillar 52 is configured to be able to expand and contract in the vertical direction, and can be expanded and contracted in the vertical direction by operating the head 61 of the lock pin 60 to release the locked state. Also, each pillar 52 can be turned over onto the transport container 1 as shown in FIG. 5 when the head 61 of the lock pin 60 is operated to release the locked state in a state where it extends to the top. Each is configured. In this case, each pillar 52 pivots about the lower end and falls over the transport container 1 through the opening surface of the holding member 51.

  Thus, each pillar 52 is configured to be vertically extendable and contractible and foldable. The portions of the pillars 52 falling on the upper surface of the third flange portion 14 respectively fit in the concave portions 17 and 17 of the third flange portion 14 in the head portion 53 so as to project toward the third flange portion 14. Further, the respective pillars 52 which fall on the upper surface of the fourth flange portion 15 also have the portions projecting toward the fourth flange portion 15 of the head portion 53 respectively fit in the concave portions 17 and 17 of the fourth flange portion 15 . As described above, since the portions of the head portions 53 of the fallen columns 52 that protrude toward the third flange portion 14 and the fourth flange portion 15 can be respectively accommodated in the corresponding recessed portions 17, they fall down. The upper surface of each pillar 52 and the upper surface 11 of the carrying container 1 can be parallel, and the overall height of the carrying container 1 and the pallet 40 can be reduced.

As shown in FIG. 4, the transport container 1 is placed on the upper surface 43 of the pallet 40 so that the columns 50 fit in the notches 30.
Here, the structure of each notch 30 will be described. Here, since the notches 30 have the same structure, the notches 30 adjacent to the second flange 13 among the notches 30 formed at both end corners of the third flange 14 are representative. Explain. FIG. 2 is an enlarged view of a region E in which the notch 30 is formed and which is surrounded by an alternate long and short dash line in FIG.
The notch 30 is a notch formed so as to surround a predetermined range of the circumferential surface of the holding member 51 that constitutes the outer side of the support column 50. In this embodiment, since the holding member 51 is formed into a hollow square pillar having a U-shaped cross section, the notch 30 is one of the four corners of the holding member 51 that is closer to the transport container 1. It is cut out in the shape which encloses two surfaces which form two corner parts, ie, a rectangle. The notch 30 includes the blocking portion 31 and the restricting portion 33. The blocking portion 31 is a portion for preventing jumping (jumping) of the transport container 1 in the upper direction (Z direction) and restricting movement of the transport container 1 in the horizontal direction (Y direction). That is, the blocking unit 31 serves both to prevent the jumping of the transport container 1 and to restrict the movement in the horizontal direction (Y direction). The restricting portion 33 is a portion that restricts the movement of the transport container 1 in the horizontal direction (X direction).

A horizontal portion 13b forming a part of the second flange portion 13 is formed in a portion adjacent to the concave portion 16 formed in the second flange portion 13, and in the direction of hanging from the edge 13c of the horizontal portion 13b. The drooping portion 32 is continuously formed. The hanging portion 32 has a shape in which the horizontal portion 13b is cut in a direction orthogonal to the second short side edge 13a, and is formed in a horizontally long rectangular shape. From the lower end edge of the hanging portion 32, the blocking portion 31 is formed so as to protrude substantially horizontally along the lower end edge. The blocking portion 31 is formed to have a rectangular longitudinal cross section.
A horizontal portion 14b forming a part of the third flange portion 14 is formed in a portion adjacent to the concave portion 17 formed in the third flange portion 14, and in the direction of hanging from the edge 14c of the horizontal portion 14b. The drooping portion 34 is continuously formed. The hanging portion 34 has a shape in which the horizontal portion 14 b is cut in a direction orthogonal to the first long side edge 14 a, and is formed in a horizontally long rectangular shape. From the lower end edge of the hanging portion 34, a restricting portion 33 is formed so as to protrude substantially horizontally along the lower end edge. The restriction portion 33 is formed to have a rectangular longitudinal cross section. The notches 30 formed at the other three corners of the container base 10 have the same structure as the notches 30 described above.

  As shown in FIG. 6, in the state where the transport container 1 is placed on the pallet 40, the tip end of the blocking portion 31 is below the head portion 61 of the lock pin 60 projecting from the side surface 51a of the holding member 51. And, it is arranged near the head 61 of the lock pin 60. Specifically, when the end of the blocking portion 31 is a vertical line with a length t1 (for example, 15 mm) lowered from the lower end of the head portion 61 of the lock pin 60, the distance t2 from the lower end of the vertical line to the hanging portion 32 ( For example, it is disposed at a position (see FIG. 7) moved horizontally by 0.5 mm. That is, the tip end of the blocking portion 31 is disposed at a position slightly displaced to the hanging portion 32 rather than directly below the tip end of the lower surface of the head portion 61 of the lock pin 60.

Furthermore, the tip of the blocking portion 31 is disposed in the vicinity of the side surface 51a from which the head portion 61 of the lock pin 60 protrudes, and a gap of length s1 is formed between the tip of the blocking portion 31 and the side surface 51a. (See FIG. 7).
Further, as shown in FIG. 7 and FIG. 8, in the state where the transport container 1 is placed on the pallet 40, the tip of the regulating portion 33 is an opening surface for taking in and out the pillar 52 among the side surfaces of the holding member 51. It is arrange | positioned in the vicinity of the opening end surface 51b to comprise. A gap of length s2 is formed between the tip of the restricting portion 33 and the opening end surface 51b (see FIG. 7). The blocking portions 31 and the regulating portions 33 provided in the notches 30 formed at the other three corners of the container base 10 have the same structure as the blocking portions 31 and the regulating portions 33 described above.

When the transport container 1 placed on the pallet 40 jumps upward (in the Z direction) due to vibration during transport, the tip of the blocking portion 31 collides with the head 61 of the lock pin 60 from below, The above jumping can be prevented. That is, it is possible to prevent the transport container 1 from jumping up more than when the blocking portion 31 collides with the head portion 61 of the lock pin 60.
In addition, when the transport container 1 placed on the pallet 40 moves in the Y direction (see FIG. 1) by vibration or centrifugal force during transport, the tip of the blocking portion 31 contacts the side surface 51 a of the holding member 51. Because of the contact, further movement in the Y direction can be blocked. That is, the container 1 for conveyance can be prevented from moving in the Y direction more than when the blocking portion 31 contacts the side surface 51a. Furthermore, when the transport container 1 placed on the pallet 40 moves in the X direction (see FIG. 1) by vibration or centrifugal force during transport, the tip end of the restricting portion 33 is at the open end face 51 b of the holding member 51. Since it abuts, further movement in the X direction can be blocked. That is, the container 1 for conveyance can be prevented from moving in the X direction more than when the front end of the restricting portion 33 abuts on the opening end surface 51b.

The positional relationship between the tip of the blocking portion 31 and the head 61 of the lock pin 60 is such that the tip of the blocking portion 31 contacts the head 61 of the lock pin 60 when the transport container 1 placed on the pallet 40 jumps. Decide to collide from below. Moreover, each flange part 12-15 has flexibility and can be deformed. Therefore, when carrying the operation of placing the transport container 1 on the pallet 40 (hereinafter referred to as loading operation) or taking out the transport container 1 mounted on the pallet 40 (hereinafter referred to as unloading operation) Even when the end of the blocking portion 31 is caught on the head portion 61 of the lock pin 60 when performing the above, each flange portion 12 to 15 is bent and deformed about the base of each flange portion 12 to 15 By doing this, the tip end of the blocking portion 31 passes over the head portion 61 of the lock pin 60, so that the placement operation and the removal operation do not occur.
However, the amount of overlap between the head portion 61 of the lock pin 60 and the tip of the blocking portion 31 (overlap amount) due to a factor such as a variation in the projection length of the tip of the blocking portion 31 or a variation in the outer shape of the transport container 1 When the loading operation and the removal operation of the transport container 1 are performed, the tip of the blocking portion 31 hardly gets over the head portion 61 of the lock pin 60, and the placement operation and the removal operation may be disturbed. is there.

Therefore, it is desirable to determine the positional relationship between the end of the blocking portion 31 and the head 61 of the lock pin 60 as follows. That is, when the carrying container 1 placed on the pallet 40 jumps, the tip of the blocking portion 31 collides with the head portion 61 of the lock pin 60 from below, and the jumping of the carrying container 1 can be prevented. Under the conditions (hereinafter referred to as jumping prevention conditions), even when the tip of the blocking portion 31 is caught on the head portion 61 of the lock pin 60 when the loading operation and the unloading operation of the transport container 1 are performed, the blocking portion The tip of the blocking portion 31 and the lock pin so that the tip of the tip 31 easily passes over the head portion 61 of the lock pin 60 and satisfies the conditions (hereinafter referred to as operation conditions) that do not interfere with the placing operation and the removing operation. The positional relationship between the sixty and the head 61 is determined.
For example, if the above-mentioned jumping prevention condition and working condition are satisfied, the tip of the blocking portion 31 is disposed directly below the head portion 61 of the lock pin 60 and the head 61 of the locking pin 60 and the blocking portion 31 It may be a positional relationship in which a predetermined distance is placed between the tip and the tip. The positional relationship may also be such that the tip of the blocking portion 31 and the lower surface of the head portion 61 of the lock pin 60 abut.

[Effect of the embodiment]
(1) If the carrying container 1 of the above-described embodiment is implemented, even if the carrying container 1 jumps when it is placed on the pallet 40 and carried, the cutaway portions When the blocking portion 31 provided on each 30 collides with the head portion 61 of the lock pin 60 projecting from the holding member 51 from below, it is possible to prevent the transportation container 1 from jumping up more than at the time of the collision.
That is, it is only necessary to place the transport container 1 on the pallet 40 so that the blocking portion 31 collides with the head portion 61 of the lock pin 60 from below when the transport container 1 jumps, as in the prior art, There is no need to bind the carrying container 1 to the pallet 40 with a band or to fix the carrying container 1 to the pallet 40 with bolts and nuts in order to prevent jumping of the carrying container 1.
Therefore, the working efficiency for preventing the shipping container 1 from jumping can be improved.
In addition, since the band, the bolt and the nut are not necessary, the cost for preventing the shipping container 1 from jumping can be reduced.

(2) Moreover, if the carrying container 1 of the embodiment described above is implemented, even when the carrying container 1 is moved in the horizontal direction when the carrying container 1 is placed on the pallet 40 and carried. When the blocking portion 31 or the regulating portion 33 provided in each notch 30 abuts on the side surface of the holding member 51, the horizontal movement of the transport container 1 can be regulated.
That is, since the movement of the conveyance container 1 in the horizontal direction can be regulated only by placing the conveyance container 1 on the pallet 40, the movement of the conveyance container 1 in the horizontal direction is restricted. There is no need to bind the carrying container 1 to the pallet 40 with a band or to fix the carrying container 1 to the pallet 40 with bolts and nuts.
Therefore, the working efficiency for preventing the transport container 1 from moving in the horizontal direction can be improved.
In addition, since the band, the bolt and the nut are not necessary, the cost for preventing the transport container 1 from moving in the horizontal direction can be reduced.

(3) Further, if the carrying container 1 of the above-described embodiment is implemented, the flanges 12 to 15 have flexibility and can be deformed, so the mounting operation or the removing operation of the carrying container 1 is performed. Even when the end of the blocking portion 31 is caught on the head portion 61 of the lock pin 60 at the time of operation, the blocking portion 31 is locked because the flange portion formed at the tip of the blocking portion 31 is bent and deformed. Since the head portion 61 of the pin 60 is climbed over, the placement operation or the removal operation of the transport container 1 does not occur.
Moreover, there is no need to insert the container 1 for transportation at an angle with respect to the pallet 40 so that the end of the blocking portion 31 does not get caught on the head 61 of the lock pin 60. Since it can be placed from directly above 40, the placement operation efficiency can be improved.

(4) Furthermore, when the loading operation or unloading operation of the transport container 1 is performed, the flange portion in which the regulating portion 33 is formed is bent even when the leading end of the regulating portion 33 is engaged with the support column 50 Since the tip of the restricting portion 33 is deformed and passes through the jammed portion, there is no possibility that the workability will be deteriorated.

(5) Furthermore, if the container 1 for conveyance of the embodiment mentioned above is implemented, the notch part 30 which was notched and formed in the shape surrounding the corner near the container 1 for conveyance among the corner parts of the holding member 51 A relatively simple configuration that can be realized by devising the shape of the transport container 1 to provide the blocking portion 31 and the restricting portion 33 in each notch 30 respectively provided at the tip of the flange portions 12 to 15 It is possible to prevent the jump of 1 and to restrict the movement in the horizontal direction.
Therefore, since it is not necessary to manufacture blocking part 31 and control part 33 separately and to attach to container 1 for transportation, the cost for the container 1 for conveyance does not jump and it does not move horizontally is reduced. can do.

(6) Each flange portion 12 to 15 has flexibility so that each flange portion 12 to 15 is caught by the head portion 61 of the lock pin 60 when the mounting operation or the removal operation of the transport container 1 is performed. Even in the case of contact with the holding member 51, the flanges 12 to 15 are bent and deformed, so the clearance formed between the notches 30 and the holding member 51 can be reduced. There is no risk of problems in placing or removing work.
Therefore, since the dead space of the conveyance container 1 can be reduced, the accommodating parts 20-23 can be enlarged that much.
(7) The blocking portion 31 can combine the blocking of the transportation container 1 with jumping and the regulation of the movement of the transportation container 1 in the horizontal direction (Y direction). That is, since the transport container 1 has a structure that serves both as a blocking portion that blocks the bounce of the transport container 1 and a control portion that regulates the horizontal movement of the transport container 1, the blocking portion and the control portion Since the configuration can be simplified as compared with the configuration in which the individual are separately provided, the manufacturing cost can be reduced.
