Abstract

PURPOSE:To provide a large carrier force even in long carrier distance and prevent the meandering of a net conveyor belt by disposing bar conveyors in contact with the net conveyor belt. CONSTITUTION:In a double net conveyor device 2 for conveying by making a net conveyor belt 4 travel under a high temperature, upper bar conveyors 14, 16, 18 and lower bar conveyors 20, 22, 24 are disposed in such a way that the bars are placed orthogonally to the conveying direction of the net conveyor belt 4 and also brought into contact with the net conveyor belt 4. Even the long net conveyor belt 4 thereby has large carrier force and is prevented from meandering. Also, even though disposed at the turn-around end part of a travel path, a knife edge turn-around guide 8 and small diameter rollers 10 are prevented from breaking, and the separation of conveyed material from the net conveyor belt 4 and the delivery of the conveyed material to the following conveyor belt can be performed positively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double net conveyor device, and more particularly, to a net conveyor device for transporting and carrying the net conveyor in a high temperature state such as a drying chamber or a frying chamber.

[0002]

2. Description of the Related Art Conventionally, a net conveyor belt transporting device drives a net conveyor belt by arranging a drive roller near the end of the traveling path of the net conveyor belt.

[0003]

When a net conveyor belt is driven by a drive roller arranged near the end of its running path as in the prior art, a large driving force is required for the drive roller, and therefore the net conveyor belt is required. A large tension is applied to. The net conveyor belt has a problem that a large tension is applied and when the net conveyor belt becomes long, the net conveyor belt partially stretches and meanders. This problem becomes particularly noticeable when the net conveyor belt is run at a high temperature.

Further, when a large tension is applied to the net conveyor belt, in order to surely separate the conveyed object from the net conveyor belt and deliver it to the next conveyor belt, the folded end portion of the traveling path of the net conveyor belt. When the knife edge folding guide and the roller having a small diameter are arranged in the above, there is a problem that the knife edge folding guide and the roller having a small diameter are broken.

Further, since it is necessary for the net conveyor to have a strength capable of withstanding a large tension, the weight of the net conveyor becomes heavy, and a large amount of heat is dissipated from the inside of an apparatus such as an oven, resulting in heat dissipation loss. There is also a problem that the product becomes thick and a large mold is attached to the product, resulting in poor peelability.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional net conveyor belt device, and is a net conveyor belt having a long conveying distance and having a large conveying force by a large driving force. In addition, the net conveyor belt does not meander, and even when a knife edge folding guide or a roller with a small diameter is arranged at the folding end of the traveling path of the net conveyor belt, these things do not break, and further, An object of the present invention is to provide a double net conveyor device capable of surely separating a conveyed object with a small heat radiation loss from the net conveyor belt and delivering it to the next conveyor belt.

[0007]

According to the present invention, in a net conveyor device for moving and carrying a net conveyor at a high temperature, a bar conveyor is arranged such that its bar is orthogonal to the carrying direction of the net conveyor belt and is in contact with the net conveyor. The double conveyor device is characterized in that it is arranged as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A double net conveyor device according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a double net conveyor device 2 arranged in a housing 1 forming a drying chamber or a frying chamber has a net conveyor belt 4, a reversing roller 6, a knife edge 8 and a pair of net conveyor belts. Drive rollers 10, 12, three upper bar conveyors 14, 16, 18 and three lower bar conveyors 2
It is driven and supported by 0, 22, and 24. The three upper bar conveyors 14, 16, 18 and the three lower bar conveyors 20, 22, 24 each have a bar conveyor drive roller 30. The net conveyor belt driving rollers 10 and 12 and the bar conveyor driving roller 30 are driven by the electric power supplied from the driving unit 32.

The upper bar conveyors 14, 16 and 18 are shown in FIG.
Multiple bars 3 attached to the chain, as shown in
4 are connected to each other so as to be orthogonal to the direction of arrow A indicating the conveying direction of the net conveyor belt 4 with a space therebetween, and three rollers 42 are provided between the drive roller 30 and the reversing roller 40. . As a result, in the vertical projection plane of the conveyor section of the net conveyor, a part of the bar conveyor where the bar does not extend is generated, so that the objects to be conveyed such as dough pieces placed on the part where the bar and the net overlap can be overlapped. It can be replaced with the part that does not become. Therefore, even if a device for sending hot air from below is used, the above replacement enables uniform heating. Lower bar conveyor 2
0, 22, and 24 are a plurality of bars (not shown) that are connected at intervals so as to be orthogonal to the direction of the arrow A indicating the transport direction of the net conveyor belt 4, and are inverted with respect to the drive roller 30. It has a roller 40.

The upper surfaces of the upper bar conveyors 14, 16, 18 and the lower bar conveyors 20, 22, 24 are in contact with the lower surface of the net conveyor belt 4, and when the bar conveyor 14 or the like is driven, this driving force is generated. 4 is transmitted. Therefore, the net conveyor belt 4 can be conveyed with a large conveying force even if a relatively small driving force is given by the net conveyor belt driving rollers 10 and 12.

In the construction described above, the upper bar conveyors 14, 16 and 18 that provide the driving force to the net conveyor belt 4 in the housing 1 are spaced from each other.
Therefore, the energy for heating the transported object (not shown) can pass through the stitches of the net conveyor belt 4 and the bars of the upper bar conveyors 14, 16, 18 and efficiently heat the transported object. can do.

[0012]

The double net conveyor device according to the present invention has a large carrying force even for a net conveyor belt having a long carrying distance and has an effect that the net conveyor belt does not meander. Further, the double net conveyor device according to the present invention does not break even when a knife edge folding guide or a roller having a small diameter is arranged at the folding end portion of the traveling path of the net conveyor belt, and these objects do not break. There is also an effect that it can be reliably peeled from the net conveyor belt and delivered to the next conveyor belt.

Further, since the bar conveyor has a portion where the bar of the bar conveyor does not exist in the vertical projection plane of the transfer section of the net conveyor, it has an effect that the transferred object can be heated uniformly. Furthermore, since it is not necessary for the net conveyor to be strong enough to withstand a large amount of tension, the weight of the net conveyor can be reduced, and the loss of heat radiation from devices such as ovens can be reduced. It also has the effect of eliminating the large mold on the mold and improving the peelability from the net conveyor.
