Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for modifying a wooden pallet.

More specifically, the present invention relates to a device that modifies the placement area of a wooden pallet on which paper or the like is placed for transportation.

[Prior Art] Conventionally, as a modification of a wooden pallet, for example, one shown in FIG. 6 is known.

This conventional modification of a wooden pallet is a wooden pallet formed in a mounting area corresponding to the standardized papermaking, printing paper, etc. The material cost will be reduced by remodeling the storage area.

That is, the wooden pallet A includes three upper and lower flat plate-shaped scoop plates 1 and 2 and three prism-shaped piers 3 arranged at the same intervals at both ends and in the center between the scoop plates 1 and 2. Sukumi board 1,
It is formed by nailing with nails 4 from the outside of 2 to fix and integrate them. Regarding this wooden pallet A, first, both scooping plates 1 and 2 are cut from near the splints 3 at both ends along the arrangement direction of the splints 3, respectively, and a pallet cut product in which the space between the scooping plates 1 and 2 on the cut surface is opened. Form Ab. Next, both of the scoop plates 1 and 2 of the pallet cut product Ab are peeled off from the pier 3 to form a pier with a nail Ab ′, and the nail 4 is pulled out from the pier with a nail Ab ′. Then, the remaining piers 3 are arranged at both ends of the pallet body Aa from which the pallet cut material Ab has been removed, and a new nail 4'is provided.
To form a modified wooden pallet A'having a reduced mounting area.

[Problems to be Solved by the Invention] In the above-mentioned modified example of the conventional wooden pallet, the nail 4 is pulled out from the above-mentioned nailed barb Ab 'by hand, such as by pulling out the nail held by the worker. Therefore, it has a problem that it cannot perform efficient work.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a remodeling device for a wooden pallet that can efficiently pull out a nail from a pier with a nail.

[Means for Solving the Problems] In order to solve the above-mentioned problems, a device for modifying a wooden pallet according to the present invention is a prismatic upper and lower scoop plates, and a prismatic prism arranged at regular intervals between the scoop plates. This is a modification of a wooden pallet in which the pier and the pier are nailed and fixed together from the outside of the pier, and both pier plates are cut along the arranging direction of the pier and the pier is removed from the pier. A long guide frame that holds the pier with nails avoiding the vertical protrusion of the nail and has a groove that can slide in the length direction of the pier, and the rotation axis is orthogonal to the guide frame in the middle upper part of the guide frame. And a rotating nail pulling mechanism for hooking and rotating the head of the nail provided on the pier with the nail.

[Operation] According to the above-described means, the nailed pier is placed on the guide frame with the nails up and down and slid in the direction of the rotary nail removing mechanism, so that the nails of the nailed pier are sequentially hooked to the rotary nail extracting mechanism. As a result, the problem of providing a remodeling device for a wooden pallet capable of efficiently withdrawing nails from a pier with nails is solved.

[Embodiment] An embodiment of the apparatus for modifying a wooden pallet according to the present invention will be described below with reference to FIGS. 1 to 7.

In this embodiment, as shown in FIG. 1 to FIG.
A slidable guide frame 6 is provided on the upper part of the nailed barb Ab ', which has a slit-shaped groove 6a for avoiding the vertically protruding nails 4 and which fits and mounts the nailed barb Ab'. .

The guide frame 6 is formed in an elongated shape that reaches both ends of the machine base 5, and a tilt angle is formed by a hinge 6b provided on the rear side of the slide and a spring 6c provided so as to elastically push upward on the entire slide side. Can be changed.

A rotary nail pulling mechanism 9 which is rotationally driven from a motor 7 via a chain 8 is provided in the upper middle part of the guide frame 6.

In this rotary nail removing mechanism 9, a triangular window hole 11 whose width is gradually narrowed in the direction opposite to the rotation direction is formed in the peripheral wall of a cylindrical rotary cylinder 9a, and the top of the window hole 11 is continuously connected. A narrow slit-shaped groove 12 is formed, and further, a linear passage groove 13 is continuously formed from the central position of the wide opening end side of the window hole 11 toward the rotation direction of the rotary cylinder 9a. At the same time, the groove 12 and the passage groove 13 are positioned on a straight line, and the grooved timber A
The nail 4 of b'can be guided and its head can be hooked. The rotary shaft of the rotary nail pulling mechanism 9 is orthogonal to the guide frame 6.

Further, in this embodiment, the discharge cylinder 10 is arranged from the side of the rotary cylinder 9a of the rotary nail removing mechanism 9 toward the lower part of the machine base 5.

According to such an embodiment, the nailed pier Ab 'is arranged so that the nails 4 of the nailed pier Ab' from which the sukumi boards 1 and 2 have been peeled off from the pallet cut material Ab cut from the wooden pallet A are placed vertically. Position the nail 4 below the groove 6a in the groove 6a
Place b'on the guide frame 6. And the pier with the nail Ab '
When the sliding member is slid toward the rotary nail pulling mechanism 9, the window 11 of the rotary cylinder 9a of the rotary nail pulling mechanism 9 rotates while the nailed shackle Ab ′ is rotated.
The nail 4 protruding upward is guided and the head of the nail 4 is hooked in the groove 12.

As a result, as shown in FIG. 4 to FIG.
The head of the nail 4 projecting above b'is hooked in the groove 12 of the rotary cylinder 9a of the rotary nail removing mechanism 9 and separated from the nailed pier Ab 'by the lever action, and the nailed pier Ab ′
Will be pulled from. In addition, such pulling action is accompanied by the sliding of the nailed timber Ab 'and the nailed timber A
It will be sequentially performed in the length direction of b '. Further, after all the nails 4 above the nailed barb Ab 'have been pulled out, the nailed barb Ab' is reversed and the lower nail 4 is pulled out.

With the pulling action of the sliding of the peg Ab 'with nails,
The degree of protrusion of the nails 4 from the piers Ab ′ with nails is not the same,
In addition, since the nails are not aligned in a straight line, the hinge 6b and the spring 6c allow the guide frame 6 to swing horizontally in the horizontal direction so that the nails can be swung in the horizontal direction.
It is possible to smoothly hook the nail 4 on the.

Therefore, the nail 4 can be efficiently pulled out from the nail-attached barb Ab 'simply by placing the nailed-barb Ab' on the guide frame 6 and sliding it. In addition, the pulled-out nails 4 are
Will be discharged by.

Incidentally, the head of the nail 4 flies and cannot be engaged with the groove 12, the nail remains as it is without being pulled out from the pier, but the window of the rotary cylinder 9a is prevented so that the nail does not interfere with the sliding of the pier Ab with a nail Ab '.
It is possible to pass through a passage groove 13 continuous to 11 and move to the next nail pulling.

As described above, in addition to the illustrated embodiment, the main body Aa of FIG. 8 can be used for disassembly and disposal.

Further, the rotary nail removing mechanism 9 may be a nail-shaped embodiment in which the nail 4 is hooked.

Furthermore, it is also possible to adopt an embodiment provided with a mechanism for automatically feeding the piers Ab 'with nails.

[Effects of the Invention] As described above, the apparatus for modifying the wooden pallet according to the present invention is
The nails can be pulled out simply by placing the pegs with nails, which are stripped from the cut pallets cut from wooden pallets, on the guide frame and sliding them. There is an effect that can be pulled out.
