Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a heating device with a variable position on a conveyor, and -
The present invention relates to a heating and conveying device for a decorative laminate that can efficiently heat a decorative laminate with a decorative sheet attached to its surface while conveying it.

[Background technology]

For example, as shown in Figs. 3 and 4, by bending a decorative board P with a decorative sheet b pasted on one side of a substrate a along its bending grooves c and d, decorative edges for construction, book blocks, etc. Although decorative materials W such as layered edges are formed, it is necessary to heat the decorative sheet B in advance in order to prevent cracks when bending the decorative material W. Moreover, such a decorative board P has a medium size and a wide variety of positions for the bending grooves c and d.

Conventionally, such a decorative board P was heated using a nichrome wire heater fixed to the fixed plate and an infrared lamp, but heating is also possible when the positions of the bending grooves c and d change. It was necessary to install it away from the decorative board P in order to moisturize and heat a wide range.

As a result, the heat rays of the heater are dissipated, the thermal efficiency is poor, and -
When the amount of heat is increased, the entire decorative sheet b is heated, resulting in wrinkles and the like.

[Purpose of the invention]

The present invention aims to provide a heating and conveying device for decorative laminates that can improve the heating efficiency of decorative laminates and prevent cracks by making the position of the heating tool variable and providing the heating tool on the conveyor. There is.

[Disclosure of the invention]

An embodiment of the decorative laminate heating and conveying apparatus 1 of the present invention will be described below with reference to the drawings, taking as an example a case where the decorative laminate heating and conveying apparatus 1 of the present invention is used to convey and heat the decorative laminate P illustrated in FIG.

The heating and conveying device 1 for decorative laminates is provided with variable-position heating tools 3A, 3B, 3C below the conveyor 2 that conveys the decorative laminate P.
(generally referred to as heating tools 3), and in this embodiment, the conveyor 2 is equipped with heating tools 4A and 4B whose positions are fixed.
, 4G (generally referred to as the heating tool 4) are arranged side by side with the heating tool 3, and a folding machine 5 is installed astride the conveyor 2 on the downstream side thereof.

The decorative board P has a synthetic resin sheet, leather,
A decorative sheet b made of synthetic paper or the like is attached, and
Bend grooves c and d are provided symmetrically on both sides of the surface of the substrate a. The outer bending groove C has a bevel of 90 degrees, and the inner bending groove d has a chevron portion d1 with an apex angle of 90 degrees.
It consists of two folded grooves d2 and d2 having a 45-degree groove with their hypotenuses facing each other, and by bending each folded WIJC, the inward facing piece P1 shown in Fig. 4 can be formed. , and by bending the bending groove d, the side piece P2 with the corner part set at 45 degrees, P2 is turned into the bottom piece P.
3 on both sides. In addition, in the decorative board P, in this example, only the dimension between the bending grooves d and d changes.

The conveyor 2 has side frames 11 and 12 on both sides of the bottom plate 10.
It consists of a roller conveyor in which rollers 13- are arranged side by side with a space between them, and a guide 1 is provided on one side frame 11, extending toward the folding machine 5 and guiding one side of the decorative board P.
4 are extended, and the heating device 4 is installed on the side frame 11 side, and the heating device 3 is installed on the side frame 12 side in the gap between the rollers 13, respectively.

The heating tool 3 includes, for example, a base frame 22 on the periphery of a rectangular bottom plate, which is widened upward and has a reflecting plate 21 with a bright inner surface and is open at the top. , a heater 2 such as a coiled nichrome wire heater is installed inside it.
3 is attached, and together with the heat generated, the heat rays can be irradiated to a relatively narrow area above.

Further, the heating tool 3 has a supporting rod 24 projecting from below the base frame 22, and the supporting rod 24 is attached to a guide shaft 33 of a pedestal 26 provided on the bottom plate 1G of the conveyor 2. The pedestal 26 has support pieces 30 and 31 erected on both sides of the lower plate 29,
The guide shaft 33 is passed between the supporting pieces 30 and 31,
A screw shaft 34 that slidably holds the support rod 24 and is rotatably supported above the guide shaft 33 and between the support pieces 30 and 31 is screwed into the support rod 24. Note that the screw shaft 34 protrudes from the support piece 30, and the protruding end has a
Install the chain wheel 36.

By forming the chain wheels 36 in two rows, chains 37 . . . can be wound between the respective heating tables 3.

A chain 41 is wound around the chain wheel 36 located at the other end of the chain wheel 36 and the deceleration motor, so that the screw shafts 34 can be rotated in unison by the forward and reverse rotation of the deceleration motor. 3A, 3B, and 3C can be traversed and adjusted all at once.

The heating tools 4A, 4B, and 4C have a similar configuration, and a support column 43 fixed to the bottom plate 10 is attached to the lower end of the Φ base frame 22. The heating device 4 is attached at a position where one side edge of the decorative board P is bent and the grooves c and d are irradiated, and the upper surface of the base frame 22 is almost in contact with the decorative board P on the conveyor 2, Also, heating tool 3A,
3B and 3C are adjusted so that the upper surface of the base frame 22 is brought close to the decorative board P and aligned with the bending groove cSd on the other side edge. Also, each heating tool 3A, 3B
, 3C, 4A, 4B, and 4C, the temperature of the heater 23 is controlled so that the temperature increases in sequence toward the bending machine 5.

However, the decorative sheet P conveyed downward by the conveyor 2 has its bending grooves cSd correctly heated by the heating device 3.4, and is efficiently and efficiently heated by having the reflective plate 21. It can be heated with high precision and is heated during transportation and folded by the folding machine 5 without causing cracks, wrinkles, etc. Furthermore, when decorative boards P with different widths are brought in, the positions of the heating tools 3 can be adjusted all at once by driving the speed reduction motor.

〔Effect of the invention〕

In this way, the decorative laminate heating and conveying device of the present invention has a heating device equipped with a reflective plate in a variable position on the conveyor that conveys the decorative laminate with the decorative sheet underneath. Since heat loss can be reduced and the decorative board can be kept warm with high accuracy, it is possible to reduce the occurrence of cracks due to insufficient heating of the bent parts of the decorative board, and because it can be heated with high precision, relatively low-quality decorative sheets can be used. It has many effects, such as making it possible to use decorative laminates that have already been used, and helping to reduce the cost of decorative laminates.

In addition, in the apparatus of the present invention, all of the heating tools are variable in position, an infrared lamp or the like can be used as a heater, and the heating tool can be modified in various ways, such as by moving the heating tool using a cylinder.
