Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pallet on which wound yarn packages are placed.

[Conventional technology]

Packages wound up by a thread winding machine are packed in boxes or stacked on top of each other and transported to the next process or shipped. In such cases, the packages are stacked in multiple tiers, and partition plates made of cardboard are interposed between the packages in each tier to prevent the packages from collapsing.

[Problem that the invention attempts to solve]

In the above case, simply installing a partition board will not work.
Even if it is possible to prevent interference of packages in the vertical direction, it is not possible to prevent interference in the lateral direction, that is, interference due to displacement of packages in the same stage during transportation.

The present invention aims to solve the above problem and provides a pallet suitable for stacking packages.

[Means to solve the problem]

The present invention is a plate-shaped body interposed between each stage of stacked yarn packages, in which a positioning peg is formed at the package mounting position of the plate-shaped body, and the peg is attached to the upper and lower surfaces of the plate-shaped body. It has first and second protruding parts that protrude, and the first protruding part that protrudes from the upper surface fits into the lower end of the winding tube of the package placed on the upper surface of the plate-like body, so that the package The second projecting portion protruding from the lower surface is fitted into the upper end of the winding tube of the package placed on the lower plate-like body to position and support the package, and the package is positioned and supported by the upper and lower plates. The first and second protrusions formed on the plate-shaped body restrict lateral movement, and the second protrusion of the positioning peg formed on the other plate-shaped body is attached to the first protrusion.
This is a pallet for a winding package in which a concave portion into which a protruding portion is fitted is formed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Figures 10 and 11 show an example of a package conveyance system to which the pallet of the present invention is applied.

Packages P produced by an automatic winder, yarn twisting machine, etc. (not shown) are suspended by hooks suspended from a conveyor line 1, for example, a chain running along a ceiling rail, and package P is suspended by hooks suspended from a chain running along a ceiling rail, and package P is suspended on package storage and conveyance lines 2A, 2B, 2C. Package delivery devices 3a, 3b, and 3c are installed at positions 3a, 3b, and 3c for delivering packages from the hooks to the conveyors of lines 2A to 2C.

Package storage and transportation line 2A at multiple locations above
~2C is composed of belt conveyors that run parallel to each other, and at the end of the package delivery side,
A package alignment line 4 is provided. moreover,
Following the line 4, a stacking station 5 and a pallet storage area 6 are arranged. The package alignment position ST1 of the alignment line 4 and the stacking station 5,
Ceiling rails 7, 7 are installed along the pallet storage area 6, and a robot 8 that is movable along the rails 7 for supporting and transporting packages and supporting and transporting pallets is installed.

FIG. 11 shows the conveyance state of the package P. That is, for example, a package Pa transferred on the storage and transfer line 2A is changed in attitude by a package transfer device 9 provided at the end of the conveyor, and the package transfer medium (hereinafter referred to as a tray 10) is circulated and transferred on the alignment line. ) is inserted into the
As shown in FIG. 10, the packages are transported together with the tray by the round belt 12 running in the direction of the arrow 11, and reach the alignment position ST1. When a predetermined number of packages (three in FIG. 1) are lined up at the alignment position, the robot 8 suspends and supports the plurality of packages at once, extracts them from the tray, and transfers them to the stacking station 5. The package is then placed on the package placement pallet 13.

When such an operation is repeated and a certain number of packages (12 in this example) are placed on the pallet 13, the robot 8 travels to the pallet storage area 6 and supports and transports the pallet 13a on the uppermost stage. , 1st
As shown in Figure 1, a pallet 13a is placed on top of the package, and the same package transfer process as described above is repeated.

Next, an embodiment of the pallet 13 suitable for stacking packages as described above will be described with reference to FIGS. 1 to 7.

In FIGS. 1 and 2, the pallet 13 is formed by fixing or integrally forming positioning pegs 15 at package mounting positions Q1 to Q12 of a plate-like body 14 made of a suitable material such as wood, synthetic resin, or cardboard. Peg 1 above
5 has first and second protrusions 16 and 17 formed on the upper and lower surfaces of the plate material 14, the first protrusion 16 supporting the lower end of the winding tube of the package, and the second protrusion 16 supporting the lower end of the winding tube of the package.
The protrusion 17 supports the upper end of the winding tube of the package. Although FIG. 1 shows an example in which the pegs 15 are arranged in a grid pattern, it is also possible to arrange them in a staggered pattern.

FIG. 3 shows the shape of the peg and the state in which the pallet is used. The peg 15 is approximately disk-shaped, and the plate material 1
A step portion 18 having a thickness equal to the thickness t of 4 is formed, and the step portion 18 is fixed to the plate material 14 to form an integral body.
A cylindrical recess 19 is formed at the center of the first protrusion 16 of the peg 15, and an annular groove 20 for supporting the winding tube is further formed.

In addition, a second protruding portion 1 protrudes from the lower surface of the plate material.
7 is a winding tube 23 of the package P, which has a substantially inverted conical shape with a step 21 formed in the middle, and the step 21 is the lower part.
It serves as a supporting surface. Note that holes 22 penetrating the upper and lower surfaces of the pegs are formed, but although these holes are not directly related to mounting the package, they can be used to reduce the weight of the board material, or to discharge fluff, dust, etc. accumulated in the concave portion 19. It is effective in preventing accumulation.

Furthermore, the pegs 15 are formed so that a plurality of pallets can be stacked on top of each other as shown in the fourth and fifth figures. That is, when only the pallets are stacked vertically, the second protrusion 17 of the upper pallet 13b can fit into the recess 19 of the lower pallet 13a. That is, the support surface 21 of the second protrusion 17
The distance h1 from to the lower end surface 24 and the depth h2 of the concave portion 19 are approximately equal, and the outer diameter d1 of the second protrusion 17 is smaller than the inner diameter d2 of the concave portion 19. Multiple palettes 13a-13
When stacking the pallets, the vertical space can be reduced, and the pallets can be stacked stably without misalignment.

The state in which the pallet is used is shown in FIG.
That is, in this embodiment, as shown in the first figure, 12 pegs are provided on one pallet, and 12 packages P1 to P are provided on the lowest pallet 13a.
12 is the concave portion 1 of the first protruding portion 16a of the peg 15;
9a, the second pallet 13b is placed on top of the 12 packages, and the second protrusion 17b of the pallet 13b is inserted into the winding tube 23 of the first package. All packages in the first stage are inserted into the upper and lower pallets 13a, 13.
b, the yarn layer surfaces of the descending package are prevented from coming into contact with each other, since lateral displacement is prevented. Similarly, the second tier of packages P13 to P24 are placed on the pallet 13b, and then the third pallet 13c and the top tier packages P25 to P36 are placed. Although a pallet may be further placed above the top package, it is not necessary to place a pallet thereon.

Although FIGS. 3 and 6 above show a case in which a truncated cone-shaped cone package is placed as the package, the same pallet can also be applied to a cylindrical cheese package as shown in FIG. 7. That is, in this case, the winding tube 26 of the cheese package 25 is cylindrical, and the lower end surface of the winding tube 26 is connected to the lower pallet 13.
The winding tube 26 is located in the annular groove 20a, and the upper end surface of the winding tube 26 is supported in contact with the support surface 27b of the upper pallet 13b. That is, the slope 28 of the second protrusion 17 of the peg 15 is for the cone package, and the slope 29
is for a cheese package, and each slope has the role of a guide when placing the pallet on the winding tube and the role of regulating the position of the upper end of the package after being placed.

Figures 8 and 9 show another embodiment of the pallet. That is, the pallet 30 has a plate part 31 and a peg part 32 integrally formed, and is formed by die-cutting from a material such as cardboard or plastic.
The peg part 32 has a first protruding part 33 on the upper side and a second protruding part 34 on the lower side, and the upper protruding part 33 is located below the winding tube 23 of the package P, as in the previous embodiment. The lower protrusion 34 supports the upper end surface of the winding tube 23 . In the stacked state of the pallets shown in FIG.
is fitted into and placed in the recess 35a of the upper protrusion 33a of the lower pallet 30a. Note that the upper and lower protrusions 33 and 34 are circular as in the previous embodiment.

Such a palette 13 or 30 is
If the pallets are stacked in the pallet storage area 6 as shown in Figs. Since the pallet is accurately positioned at the pallet storage area, it can be transferred to a predetermined package stacking station 5 with a simple operation.

Furthermore, the packages placed on each pallet are positioned by pegs formed on the upper and lower pallets, and are transported from the stacking station 5 to the next process while being loaded on the pallet without touching adjacent packages. It is possible.

In the above description, the article placed on the pallet is a wound yarn package, but it is of course applicable to other articles having a similar shape.

[Effect of idea]

As described above, according to the present invention, a position regulating member is provided on the pallet located between each stage of the stacked yarn packages to fit into the winding tubes of the packages above and below the pallet for positioning. So,
The packages in each stage do not shift in the front, back, left, or right lateral directions and the surfaces of the yarn layers come into contact with each other, and the yarn layer can be transported while being placed on the pallet without damaging the yarn quality. Moreover, since the first protrusion has a recess into which the second protrusion of the positioning peg formed on the other plate-shaped body fits, it saves space in the vertical direction when storing multiple pallets in a stack. can be reduced and stacked stably.
