JPS5859155A - Portioning method for sheets by oversurface transport - Google Patents

Abstract

PURPOSE:To enhance the transport efficiency by transporting sheets to which heat resistant wires coated with a molten resin are attached. CONSTITUTION:Piano wire etc. having a heat resistance below 100-200 deg.C and an abrasion resistance to sustain repeated use is coated with a resin 2 molten by heating to 100-200 deg.C approx., and two or more of such wires 1 are continuously sent out in cooling to attach in the form of a bamboo screen to the oversurface of a single plate for venner board 3 to be solidified into a single body under pressure, whereafter the wires 1 attached to the oversurface of the sheet 3 are torn selectively at two or more portioning places in the transport process to be collected at the forestage while the sheets 3' are portioned at later stage to be carried out. Thus the quick carrying performance and energy saving performance can be enhanced.

Description

Detailed Description of the Invention (Objective of the Invention) The present invention relates to a method for sorting thin sheets such as veneer medium plates, veneer plywood, various fiber-inserted sheets, metal plates, synthetic resin plates, etc. by top-side conveyance. The purpose of this method is to sort thin sheets by size, grade, etc. while continuing to transport them. Is it an open/close conveyor type in which the conveyor is supported by the body and the upper surface is driven by a conveyor to continue conveyance?
Or is it a suction conveyor system where the top surface of the thin plate is sucked onto a perforated belt etc. using the suction force of a fan and continues to be conveyed?
Alternatively, the top surface of the thin plate was stuck on a needle belt and conveyed using a piercing conveyor system, so the opening/closing conveyor system had a limit on the opening/closing speed of the opening/closing body located on the bottom surface, making it difficult to handle high speeds. The chipping and suction conveyor type requires a large amount of power due to the low efficiency of the fan that generates the suction force, so it is not energy efficient.The sticking conveyor type punctures the thin plate, making it difficult to use for general use. However, by developing a top surface conveying technology for thin sheets that eliminates all of the shortcomings of conventional technologies and is excellent in high-speed response, energy saving, and versatility, we have developed This is an attempt to provide a new sorting method such as sorting by size and one grade by top surface conveyance.

(Structure of the Invention) The present invention comprises a first step of continuously applying a molten hot melt resin 2 to an endless filament 1 having a heat resistance and a lubricity of 1", such as a piano wire; A second step in which the filament 1 coated with the resin 2 is continuously fed out onto the upper surface of the thin plate 6 during the conveyance process, cooled and pasted, and the thin plate 6
i, 3-■] Then, the attached filament 1 is selectively peeled off at multiple sorting locations during the conveyance process, and the filament 1 is collected in the first process, and the filament 6' is sent to the subsequent process. This is a sorting method by one-plane conveyance of thin plates, which is composed of a sixth step of sorting and carrying out.

That is, as shown in the figure, an example of the implementation of the present invention is to coat the upper surface of a thin plate 3 such as a veneer veneer with a piece of piano wire or the like having heat resistance of 100 to 200°C or less, resistance to repeated use, and wear resistance. A molten hot null 1 resin 2 heated to about 100 to 200°C is applied to the filament 1, a plurality of five pieces are continuously fed out 7, and the mixture is cooled by an appropriate means such as air cooling or water cooling while being pressed and solidified as one body. By pasting them in a blind shape, the thin plate 6 can be supported from the upper surface by the adhesive force of the filament 1 and its conveyance can be continued. The method of the present invention will be further described in detail with respect to an example of an apparatus for carrying out the present invention on the ship's side. The filament 1, such as piano wire, which has heat resistance and abrasion resistance shown in the drawing is connected endlessly, and this is called cold pressure row/L/4 + peeling row/'5.
+Guide rows/L/L/6a, 6b, etc. are rotatably suspended from each other, and are heated in the container 2 by an appropriate heat source, such as an electric heater, in front of the cold pressure row (v4). Application nozzle for molten hot melt resin resin fj 2)
V 7 is provided in its rotation path, and the first step is such that an appropriate amount of molten hot melt resin 2 is continuously applied to the outer periphery of the filament 1 and fed out. .

On the other hand, when the thin plate 6 in the conveyance process is carried in by the carry-in conveyor 8 to just below the cold pressure row/L/4, a plurality of filaments 1 whose outer peripheries are coated with the molten hot melt resin 2 are fed out onto it. The second step is such that the thin plate 6 is pasted in the form of a blind by being cold pressed and the filaments 1 perform the function of conveying the thin plate 6 to the upper surface thereof. In addition, the upper surface of the thin plate 6 is conveyed by the AiJ line 1, so that it can vibrate freely so as to go around to the side of the line 1, for example, by means of a plurality of air cylinders, etc., which are capable of controlling the appearance and retraction, provided in the middle of the conveyance process. The thin plates 6' are selectively peeled off from the filament 1 by the provided peeling claws 9, and are sorted and delivered to the corresponding carry-out conveyor 10-L directly below.
In addition, at the end of the conveyance i, the remaining 4 temporary 6'' of the entire length is continuous from the filament 1 by a peeling IJ-rule 5 with a diameter larger than the filament 10 provided at the end. The sixth stage is designed so that the sixth stage is peeled off and delivered to the unloading conveyor 10'H directly below.
The filament 1, which was peeled off and recovered from the upper surface of the thin plates 6' and 6'' in the step, is fixed to the hot melt resin 2 on the outer periphery by a cleaning member 11 such as a die provided in front of the 7p cloth nozzle 7. (2) Wipe away the excess deposits 12, such as wood chips, that have been peeled off from the upper surfaces of the thin plates 3' and 3'', and (2) remove the debris to -F of the scrap conveyor 15, etc. below, and remove this. The device can be configured to circulate and supply the liquid to the first step consisting of the coating nozzle lv7 again.

In the figure, reference numeral 14 denotes a wet roll for applying a cooling medium such as water to the cold pressure roll 4.

(Effects of the Invention) As described above, the present invention provides a method for applying molten hot melt resin 2 to a filament 1.
A first step of coating the outer periphery of the thin plate 6, a second step of cold-pressing it on the upper surface of the thin plate 6, and then selectively peeling off the thin plate 6 and the filament 1 at a plurality of sorting locations to form the thin plate 6. Since this is a sorting method based on top surface conveyance of thin plates, which consists of the sixth step of sorting the strips 1 and collecting the filaments 1 for circulation, the opening/closing speed of the opening/closing body located on the bottom surface of the prior art opening/closing conveyor system is The drawbacks are that it has strange limitations and lacks high-speed support, and the efficiency of the fan that generates the suction force of the suction conveyor type is second to none, so it requires a large amount of power and lacks energy conservation.
Learn how to stab wounds on the thin plate of the tattoo conveyor system (all the disadvantages of limited quality and lack of versatility have been overcome, and we have developed a thin plate with excellent high-speed response, energy saving, and versatility). This is the first invention to provide a new U: component force method, such as size separation and equal step separation, by using resin UfJ conveyance technology to strictly feed thin plates from the top surface, and is an invention with extremely remarkable implementation effects6.
