Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver grilling apparatus for continuously baking laver in a heating chamber while transporting the laver in a heating chamber, wherein the belt of the belt conveyor is prevented from meandering when the laver is transported.

  Grilled laver, which is made from grilled laver, is widely used for laver rolls, seasoned laver, and rice balls. Baked laver is heated and baked while transporting plate laver in a heating chamber of a laver grilling device while transporting the plate laver with a belt conveyor (see Patent Document 1).

  FIG. 4 shows an example of a conventional laver grilling apparatus. In FIG. 4, a belt conveyor 2 for transporting plate laver is arranged below a plurality of heaters 3 arranged in a heating chamber 1. The plate laver placed on the belt conveyor 2 is heated and baked during transportation.

  In the belt conveyor 2, a driven pulley 5 is disposed on a side of the laver loading side, and a driving pulley 6 is disposed on a side of the roasted laver discharging side. An endless belt 7 is stretched between the driven pulley 5 and the driving pulley 6, and the endless belt 7 rotates between the pulleys 5 and 6 by the rotation of the driving pulley 6. The belt 7 of the belt conveyor 2 is formed of, for example, a heat-resistant metal or resin formed in a mesh shape.

  In the laver grilling apparatus, the plate laver is conveyed on the belt 7 in two rows in the width direction at intervals continuously in the traveling direction of the belt 7. The plate laver being conveyed is heated by the heater 3 and usually baked while being heated in an atmosphere of 200 ° C. to 250 ° C.

  However, during the operation of the laver grilling apparatus, the temperature in the heating apparatus 1 rises to 200 ° C. to 250 ° C. due to the heat of the heater 3, and accordingly, the temperature of the belt conveyor 2 also rises and the belt 7 expands. Was growing. A phenomenon occurs in which the running belt 7 meanders due to the elongation of the belt 7, and the meandering of the belt 7 causes the belt 7 to come off the pulleys 5 and 6, or the edges of the plate nori hit the walls of the heating chamber and fall off. Or a malfunction that occurred.

  Therefore, means for preventing meandering of the endless belt have been proposed. For example, an endless belt shown in FIG. 5 is one example. In FIG. 5, a pair of guide grooves 10 are formed on both sides of each of the driving pulley 6 and the driven pulley 5 and in parallel with each other in the circumferential direction.

  On the other hand, on the inner side of the endless belt 7 (on the side in contact with the pulley), a pair of guide ridges 11 guided into a pair of guide grooves 10 formed in each of the pulleys 5 and 6 are guided all around the endless belt 7. Is a belt conveyor with a guide formed parallel to the belt. In the belt conveyor with guides, the guide ridges 11 of the endless belt 7 enter the guide grooves 10 formed in the respective pulleys 5 and 6 and are guided during the travel of the endless belt 7, so that the guide ridges 11 are provided. Is restricted, so that the belt 7 can be prevented from meandering.

  However, in the above-described belt conveyor with guides, it is necessary to form guide grooves on both sides of the pulley, and to form guide ridges inside the endless belt, so that it takes time to process the pulley and the belt. In addition to the complicated manufacturing, the belt may meander as the guide ridges come off the guide grooves due to wear.

  Accordingly, the present invention provides a laver grilling apparatus that can prevent belt meandering with a simple structure without processing a pulley or a belt.

The invention according to claim 1 of the present application is a laver grilling apparatus for baking plate laver while transporting the plate laver in a heating chamber, wherein the belt conveyor comprises a pulley disposed on the plate laver carry-in side of the heating chamber and a baking of the heating chamber. An endless belt is rotatably hung between a pair of pulleys disposed on the laver carry-out side, and the lower belt is provided on both sides in the width direction of the lower belt of the endless belt between the pair of pulleys. A pair of inclined rollers that are inclined upward and divergent are arranged on the upper side to apply tension by pushing up both edges from below, and the pair of inclined rollers are inclined upward by 10 to 80 ° from horizontal and the inclination angle is adjustable. The laver grilling device is supported by blankets on both sides of the lower belt .

  The present invention provides a simple structure in which inclined rollers are arranged on both sides of a belt on the lower side of an endless belt without processing guide grooves and guide ridges on pulleys and belts. By applying tension to the belt, it is possible to prevent the belt from meandering by restricting movement of the belt in the width direction.

BRIEF DESCRIPTION OF THE DRAWINGS It is the schematic which shows the whole laver apparatus of this invention. FIG. 3 is a view showing a tilt roller according to the present invention. FIG. 4 is a view showing an arrangement of a tilt roller according to the present invention. It is the schematic which shows the whole conventional laver grilling apparatus. It is a figure which shows the conventional belt meandering prevention means.

  One embodiment of the laver grilling apparatus of the present invention will be described with reference to the drawings.

  1 to 3, the laver grilling device of the present invention includes a heating chamber 1, a belt conveyor 2 and a heater 3 in the heating chamber 1, except for an inclined roll 4 for preventing the belt 7 from meandering. It has the same configuration as the conventional laver grilling apparatus shown in FIG.

  In the heating chamber 1, a belt conveyor 2 for transporting the plate laver from the plate laver carry-in side to the grilled laver carry-out side is arranged. Above the belt conveyor 2, a plurality of heaters 3 are arranged at intervals along the transport direction of the plate nori. For example, when the heater 3 is at about 300 ° C., the atmosphere is at about 200 ° C. to 250 ° C., and the conveyed plate laver is baked.

  A driven pulley 5 is arranged on the plate nori carry-in side of the heating chamber 1, a drive pulley 6 is arranged on the grilled nori carry-out side of the heating chamber 1, and an endless belt 7 is stretched between the driven pulley 5 and the drive pulley 6. The endless belt 7 rotates between the pulleys 5 and 6 by the rotation of the driving pulley 6. The endless belt 7 is formed of a heat-resistant metal or resin (for example, Teflon) belt formed in a mesh shape.

  On both sides in the width direction of the endless belt 7 stretched between the driven pulley 5 and the driving pulley 6, the lower belt 8 is pushed up below the lower belt 8 to prevent belt meandering. A pair of inclined rollers 4 are provided on the upper side for applying tension to the belt 8 and preventing meandering of the belt 8 during running.

  The inclined roller 4 is supported by blankets 9 on both sides of the lower belt 8, and the inclination angle can be adjusted. Further, bearings 4a and 4b are provided above and below the inclined roller, so that the roller rotates while contacting the lower belt 8.

  The installation position of the inclined roller 4 is not particularly limited as long as it is between the driven pulley 5 and the driving pulley 6, but the plate laver outside the heating chamber having a space outside the normally closed heating chamber is carried in. If installed on the side or the grilled laver carry-out side, inspection and maintenance becomes easier.

  The inclined roller 4 is installed at an angle which supports the edge of the belt from both sides of the lower belt 8 and pushes the belt upward. The inclined roller 4 is inclined from the horizontal to the upper side in the range of 10 to 80 ° depending on the strength of the belt. The belt 8 is pushed up and supported.
