られている。2. Description of the Related Art The above-mentioned hot plate type continuous welding apparatus uses a heater for heating a predetermined position facing a feeding path of a synthetic resin sheet (hereinafter referred to as a sheet in this specification) continuously fed in a certain direction. This is an apparatus in which a plate is installed, and the sheet is heated by the heat of the hot plate to a temperature range in which the sheet can be welded and the sheet is welded. Such an apparatus itself has been conventionally known.

うにしてある。In this hot plate type continuous welding apparatus, generally, the set temperature of a hot plate type heating unit (hereinafter referred to as a heating unit in the present specification) including a heater and a hot plate, that is, the temperature of the hot plate is from room temperature. Any temperature can be set within the temperature range of several hundreds of degrees, so that different welding temperature ranges can be accommodated depending on the type of sheet (type of synthetic resin used in the sheet). .

加工を行うことが多い。When a sheet is welded using such a hot plate type continuous welding apparatus, if the set temperature of the heating unit is raised too high, the welding surface of the sheet faces the heating unit before the temperature reaches the feasible temperature range. The temperature of the non-welded surface of the sheet rises too much and wrinkles occur in the sheet, and the non-welded surface of the sheet melts, so that a good finished state cannot be obtained. Therefore, in order to prevent such a situation from occurring, the welding process is often performed without raising the set temperature of the heating unit too much, that is, the set temperature is lowered.

いて顕著に生じていた。However, when the set temperature of the heating unit is set low, it takes a long time for the temperature of the welding surface of the sheet to reach the temperature range in which welding is possible. In order to carry out various welding processes, the sheet heating time is lengthened by slowing the sheet feeding speed or increasing the creeping length of the heating unit relative to the non-welding surface of the sheet, and the temperature of the welding surface of the sheet is increased. Need to reach the temperature range where welding is possible. Therefore, in the conventional hot plate type continuous welding device,
Even if reliable welding can be performed, there is a problem in that it is difficult to improve productivity because the sheet heating time is lengthened by increasing the sheet heating time. This problem has been particularly noticeable in a sheet using a synthetic resin such as vinyl acetate or ethylene tetrafluoride having a narrow feasible temperature range.

じない。According to the sheet hot plate type continuous welding apparatus of the present invention, the set temperature of the first heating unit in the heating units arranged in multiple stages is kept low and the first to the last stages are set. By sequentially increasing the set temperature toward the heating unit, the welding process is performed in a state where the temperature difference between the non-welding surface of the sheet facing the heating unit and the welding surface of the sheet is reduced. Therefore, even if the total heating time by all the heating units is shortened, the temperature of the non-welding surface of the sheet facing the heating unit will rise too much before the welding surface of the sheet reaches the feasible temperature range. Does not happen.

溶着面の温度が上がりすぎるという事態を生じない。Further , the heat of the heating unit of each stage is transferred to the seat through the forward traveling portion of the endless belt. Therefore, the forward running portion of the endless belt is repeatedly heated by the heating unit in each stage every time the endless belt performs one cycle (one rotation). However, since the forward traveling part of the endless belt is cooled by the cooling unit every time it passes through the heating area by the heating units of all stages, the forward traveling of the endless belt is repeated no matter how many cycles it takes for a long time. The temperature rise of the part is forcibly suppressed below a certain level. Therefore, even if continuous operation is performed for a long time, the temperature of the non-welded surface of the sheet facing the heating unit does not rise too much before the welded surface of the sheet reaches the feasible temperature range.

得られる。Next, the operation will be described. For example, the lower heating unit 71A and the upper heating unit 71B in the former stage have the same set temperature, the lower heating unit 72A in the latter stage and the upper heating unit 72B have the same set temperature, and the lower heating unit 72A in the latter stage and the upper heating unit 72A have the same set temperature. The temperature of the heating unit 72B is set to be slightly higher than the set temperatures of the lower heating unit 71A and the upper heating unit 71B in the previous stage. In this way, the temperature of the heating units 71A, 71B, 72A, 72B at the top and bottom of each stage is set, and then the feed path 6 is passed through the guide roller 91.
When the welding surfaces S1 "and S2" of the sheets S1 and S2 are superposed and fed, the upper and lower endless belt-shaped bodies 2A and 2B travel and the sheets S1 and S2 move in the feeding path 6 in the arrow X direction at the same speed. The sheets S1 and S2 are sent and heated by the upper and lower heating units 71A and 71B, and subsequently, the rear upper and lower heating units 72A and 72B.
Heating at a higher temperature with B takes place. In this case, the heating of the sheets S1 and S2 is performed via the forward traveling portions 21A and 21B of the upper and lower endless strips 2A and 2B. Then, in this way, the upper and lower heating units 71
The sheets S1 and S2 are preheated by A and 71B,
The preheated sheets S1 and S2 are heated at a higher temperature than the latter heating units 72A,
72B, each heating unit 71A, 7
Welding is performed in a state where the temperature difference between the non-welded surfaces S1 ', S2' and the welded surfaces S1 ", S2" of the sheets S1, S2 facing 1B, 72A, 72B is small. Therefore, the feeding speed of the sheets S1 and S2 is increased to increase the heating units 7 of all stages.
Even if the total heating time by 1A, 71B, 72A, 72B is shortened, the heating units 71A, 71B, 72 are heated before the welding surfaces S1 ", S2" reach the welding temperature range.
A situation in which the temperatures of the non-welding surfaces S1 ′ and S2 ′ facing A and 72B rise too much does not occur.
A good finished state without wrinkles and melting traces on 1'and S2 'can be obtained.

A and 21B are heating units 71A, 71B and 72A,
After passing through the heating area by 72B, it is cooled by the upper and lower cooling units 73A and 73B. Therefore, no matter how many cycles the endless belts 2A and 2B are cycled over a long period of time, the temperature rise of the forward traveling portions 21A and 21B is forcibly suppressed to a certain level or less. Welding surface S of sheets S1 and S2 even after continuous operation over time
It does not occur that the temperatures of the non-welded surfaces S1 ′, S2 ′ facing the heating units 71A, 71B, 72A, 72B rise too high before 1 ″ and S2 ″ reach the temperature range where welding is possible. Therefore, the finished state of the welding process is good over the entire length of the long sheet.

It is possible to increase the speed, and there is an effect that productivity is improved.
In addition, since it is not necessary to increase the creeping length of the heating unit with respect to the non-welded surface of the sheet in order to perform the welding process with a good finished state, the effect that the heating unit is downsized and the heat conduction to the sheet is increased. Since the temperature of the forward running part of the endless belt functioning as a path is forcibly suppressed below a certain level even if the operation is continued for a long time, even if the continuous operation is performed for a long time, a good welding finish is obtained.
