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.
When stacking the bars 1, which are manufactured in two halves, as shown in Fig. 3, the handling is complicated as it requires rearrangement of the bars 1, so mechanization is not possible and the process is done manually. Therefore, it was inefficient.

Therefore, an object of the present invention is to provide a sheet-covered bar material that can be efficiently and easily assembled using simple equipment in order to stack sheet-covered bars produced in two halves so that their coated surfaces match each other. The objective is to provide a method for accumulating

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 carry-in conveyor, 6 is a horizontal feed conveyor, 7a and 7b are two rows of vertical feed conveyors, and 8 is a stacking device. The starting end of the incoming conveyor 5 is connected to a sheet covering device for manufacturing the double-width bar 1' shown in FIG. 2, and a reversing device 9 and a cutting machine 10 are installed in the middle of the incoming conveyor 5. The cutting machine 10 consists of a circular saw, a band saw, or the like. At the starting end of the traverse conveyor 6, an elevating roller conveyor 11 is provided which transfers the bar material 1 from the carry-in conveyor 5 to the lateral conveyor 6. Further, at the terminal end of the horizontal conveyor 6, two rows of elevating roller conveyors 12a and 12b are provided for conveying the bars 1 to vertical conveyors 7a and 7b. These two rows of roller conveyor 12
a and 12b have a width on which one bar 1 can be placed.

The reversing device 9 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.

The laminating device 8 is constructed as shown in FIGS. 9 and 10. 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 composed of a roller conveyor, and in a mutually closed state, the vertical feed conveyors 7a and 7 shown in FIG.
Consistent with b. 27 is a stopper for dropping the bar material, and is fixed to the base frame 24. Loading table 2
A table lifter 28 is installed below the table lifter 5, and a pair of vertical laminated guide plates 29 face each other on both sides of the table lifter 28.
is attached to the base frame 24.

Next, a method of stacking using the stacking device will be explained. First, the double-width bars 1' shown in FIG. 2 are sequentially carried into the carry-in conveyor 5 shown in FIG. 4 with their faces facing up. The first of these double-width bars 1' passes through the reversing device 9 face up without being reversed and advances toward the cutting machine 10. The second one is turned upside down as it passes through the turning device 9. In this way, the double-width bars 1' are sequentially and alternately carried into the cutting machine 10 with the front and back facing reversed. The cutting machine 10 cuts the double-width bar 1' at the center into two symmetrically shaped bars 1. In this state, two bars 1
As shown by solid lines in FIG. 7 or FIG. 8, the side surfaces 1b not covered with the sheet 2 are oriented adjacent to each other, and while the sheets are being conveyed from the horizontal conveyor 6 to the vertical conveyors 7a and 7b. , as shown by the chain line in FIG. 7 or 8, the sheet covering side surface 1a
Arrange them so that they are next to each other.

The sorting operation will be explained. Two bars 1 ₁ , 1 2 are conveyed from the cutting machine 10 to the transverse conveyor 6 in line with the solid line in FIG. ₇ (FIG. 6A)
The bars 1 _{and 2} on the lower side in the traverse direction are transported horizontally as they are, and the bars 12 on the lower side in the direction of traverse transport are transferred to the elevating roller conveyor 12a (Fig. 4).
The lateral feed is stopped when the upper position is reached (FIG. 6B). Then, the elevating roller conveyor 12a floats up and the lower bar ₁₂ is vertically fed from the elevating roller conveyor 12a onto the vertical conveyor 7a (FIG. 8C). Thereafter, the remaining bar material ₁₁ is again driven by the transverse feed conveyor 6 and sent above the elevating roller conveyor 12b. Next, this bar ₁₁ is vertically fed by the lifting roller conveyor 12b from the lifting roller conveyor 12b to the vertical conveyor 7b, and the bars ₁₂ that have been vertically fed first are lined up.

When the sorting is completed in this way, the two lined up bars 1 ₁ , 1 ₂ are transferred to the vertical feed conveyors 7 a, 7
b is carried into the carrying table 25 of the laminating apparatus 8,
The carry-in table 25 is opened on both sides and dropped onto the table lifter 28. Each time the table lifter 28 receives a bar 1, it is lowered by the thickness of one bar 1. In the same manner, the bars 1 which are turned face down as shown in FIG. 8 are also loaded on the table lifter 28 after being rearranged. In this way, the bars 1 facing up and the bars 1 facing down are stacked alternately, resulting in a stacked state in which all sheet covering surfaces are in contact with each other as shown in FIG. In this way, the sheets are stacked with their coated surfaces together, but in addition to the stacking device 8, the transverse conveyor 6
By simply providing the elevating roller conveyors 12a, 12b and the reversing device 9, the bar 1 can be turned so that the sheet-covered surfaces are aligned.
The equipment is simple and the accumulation work can be carried out efficiently.

Note that the cutting machine 10 and the reversing device 9 may be rearranged so that the cutter is reversed after cutting, or the reversing device 9 may not be used and the reversing device 9 may be manually reversed. Furthermore, instead of the elevating roller conveyors 12a and 12b provided at the terminal end of the horizontal conveyor 6, an extrusion device for extruding the bar material 1 to the vertical conveyors 7a and 7b may be provided.

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 transporting the bars horizontally and vertically along the way. Since the sheets are rearranged by combination so that the coated sides of the sheets meet together, and they are sequentially dropped and stacked at the end of conveyance, the sheet-coated bars that are manufactured in half can be efficiently stacked so that the coated sides meet. This has the advantage that simple equipment is sufficient.
