Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for stacking sheet-covered bars.

Traditionally, it has been used as a bar material for opening frames in houses, etc.
As shown in FIG. 1, a wooden bar 1 whose surface and one side are covered with a sheet 2 is used. The sheet 2 is made of vinyl chloride resin or the like.
3 is a chamfered portion. When manufacturing such a bar 1, in order to streamline the sheet coating work, a double-width bar 1' is coated with the sheet 2 as shown in Fig. 2, and this is cut at the center 4. This is called bar 1 in Fig. 1. In addition, when packing this bar material 1, a third
As shown in the figure, the sheets 2 are stacked with their coated surfaces aligned. However, in the past, the double-width bar 1' shown in Fig.
In order to stack the bar materials 1, which are produced in two parts, as shown in FIG. 3, it cannot be mechanized and has to be done manually, resulting in inefficiency.

Therefore, an object of the present invention is to provide a sheet-covered bar that can be stacked efficiently and with simple equipment in order to stack sheet-coated bars that are manufactured in half so that the coated surfaces match each other. The purpose is to provide an accumulation method.

An embodiment of this invention is shown in FIGS. 4 to 10. First, the integration device will be explained. In FIG. 4, 5 is a roller conveyor, and its path includes a reversing device 6, a cutting machine 7, a sorting device 8,
A laminating device 9 is installed in this order. The starting end of the roller conveyor 5 is connected to a sheet coating device for producing double-width bars 1' as shown in FIG. The cutting machine 7 consists of a circular saw, a band saw, or the like.

The reversing device 6 is for reversing the double-width bar 1' vertically, and is constructed as shown in FIG.
That is, 13 is a reversing drum supported by rollers 14, and is rotationally driven by a motor 15 via a chain 16. The reversing drum 13 has two rows of internal conveyors 17 facing each other, between which the double-width bar 1' is conveyed.

As shown in FIGS. 6 to 8, the sorting device 8 includes a lateral conveyor 18 and a bar lifting device 19.
It consists of. The lateral conveyor 18 rises and falls with respect to the conveyance surface of the roller conveyor 5 by driving a pantograph-type lifting mechanism 18'. Note that the lateral conveyor 18 may be fixed and the roller conveyor 5 may be moved up and down over a certain section. The bar lifting device 19 consists of a lifting cylinder 20 in a fixed position and a U-shaped lifting piece 21 attached to the piston rod of the lifting cylinder 20. A plurality of horizontal feed conveyors 18 are installed in parallel,
A plurality of lifting cylinders 20 are also arranged in parallel.

The laminating device 9 is constructed as shown in FIGS. 10 and 11. In the figure, reference numeral 24 denotes a pair of base frames arranged in parallel, and two rows of carry-in tables 25 are installed on these base frames 24 via cylinder devices 26 so as to be openable and movable outward from each other. The carry-in table 25 is constituted by a roller conveyor, and is aligned with the roller conveyor 5 of FIG. 4 in a mutually closed state. 27 is a stopper for dropping the bar material, and is fixed to the base frame 24. A table lifter 28 is installed below the loading table 25, and a pair of vertical laminated guide plates 29 face each other on both sides of the base frame 2.
It is attached to 4.

Next, a method of stacking using the stacking device will be explained. First, the roller conveyor 5 shown in FIG.
The double-width bars 1' shown in the figure are sequentially carried in with their faces facing up. The first of these double-width bars 1' passes through the reversing device 10 face up without being reversed and advances toward the cutting machine 7. The second one is flipped upside down as it passes through the flipping device 10. In this way, the double-width bars 1' are sequentially and alternately conveyed into the cutting machine 7 with the front and back facing reversed. The cutting machine 7 cuts the double-width bar 1' at the center into two symmetrically shaped bars 1. In this state, the two side-by-side bars 1 have side surfaces 1b not covered with the sheet 2 adjacent to each other as shown in FIG. 8, and are sorted by the sorting device 8 as shown in FIGS. Sort.

The sorting operation will be explained. When the bars 1 are carried into the sorting device 8, they are lifted by the traverse conveyor 18 as shown by the chain line in FIG. 9A. This bar 1 is fed horizontally by a horizontal conveyor 18 until it hits a U-shaped lifting piece 21. Then, the U-shaped lifting piece 21 is lifted by driving the lifting cylinder 20.
One bar ₁₁ is lifted, and the other bar ₁₂ continues to be fed horizontally (Fig. 9B). After this, the lifting cylinder 20 is extended again and the bar 11 of the U-shaped lifting piece ₂₁ is transferred to the lateral conveyor 1.
8 (FIG. 9C), the transverse feed conveyor 18 rotates in the return direction, and the bar 1 ₁ is lowered to the U-shaped lifting piece 21.
Get out of. Then, the U-shaped lifting piece 21 rises again, and both bars 1 ₁ and 1 ₂ are moved to the roller conveyor 5.
returned to the side. (Figure 9D). The bar ₁₁ on the right side of FIG. 9D stops when it hits a suitably provided stopper, and the bar ₁₂ on the left side is returned until it hits the bar ₁₁ on the right side. In this way, the bar 1 (1 ₁ ,
1 ₂ ) are rearranged so that the sheet-covered side surfaces 1a are adjacent to each other. Although FIG. 9 describes the case where the two bars 1 are carried in face down, they can be rearranged in the same way even if they are carried in face up.

The bar materials 1 that have been rearranged are returned onto the roller conveyor 5 by the lowering of the transverse feed conveyor 18, and are carried by the roller conveyor 5 to the carry-in table 25 of the stacking device 9. And both loading tables 2
5 are opened from each other by the drive of the cylinder device 26, the bars 1 are dropped onto the table lifter 28 and stacked as shown in FIG. table lifter 2
8 is lowered by the thickness of one bar each time the bar 1 is stacked. In this way, the sheets 2 are stacked so that the side surfaces 1a covered with the sheets 2 are aligned. Moreover, since the bars 1 are alternately transported into the stacking device 9 with their front and back sides turned upside down, the stacked bars 1 are stacked so that their surfaces are aligned with each other. In this way, the sheets are stacked with their coated surfaces aligned with each other, but simply by providing the sorting device 11 and the reversing device 10 in addition to the stacking device 9, the bars 1 can be stacked with their sheet coated surfaces aligned. It is simple and allows for efficient collection work.

Note that the cutting machine 7 and the reversing device 6 may be rearranged so that the cutter is reversed after cutting, or the reversing device 6 may not be used and the reversing may be performed manually. In addition to the above-mentioned arrangement device 8, devices having various structures can be used.

As described above, the method for accumulating sheet-covered bars of the present invention involves arranging two bars at a time and transporting them alternately upside down, and then rearranging the transported bars midway so that the sheet-covered sides are brought together. By doing so, the layers are stacked sequentially at the end of the conveyance position.
This method has the effect that sheet-covered rods produced in two pieces can be efficiently stacked so that their coated surfaces meet, and that simple equipment is sufficient.
