Description

  The present invention relates to a wire mesh belt suitable for use in producing light foods such as confectionery such as rice crackers and a transport machine for food production equipment.

  Light food products such as confectionery such as rice crackers are manufactured through a kneading process, a rolling process, a die cutting process, a drying process, a baking process, and the like. In particular, a wire mesh conveyor is used as a transfer means in the drying process and baking process. (For example, refer to Patent Documents 1 and 2.) For example, in the drying process or baking process when manufacturing rice crackers, this wire mesh conveyor is loaded with rice cracker dough that has been cut into various shapes and thicknesses, and is transported through a hot air drying chamber or a baking apparatus. It is used to dry and bake rice cracker dough.

This wire mesh conveyor has endless chains attached to both sides thereof, and a pair of endless chains are connected by a plurality of cross bars arranged at equal intervals, and stainless steel or zinc wire mesh is connected to these cross bars with the same material. It is tied and attached with a wire (not shown). In the wire mesh conveyor, fasteners are attached to appropriate positions of the cross bars in order to prevent the wire mesh from being displaced.

  The previously known wire mesh conveyor requires a sprocket as a member for passing the endless chain in addition to the driving roller and the driven roller, and also forms a pair of long endless chains, a plurality of cross bars, and a wire mesh to these cross bars. It is expensive to manufacture, and it is lubricated by applying it between the endless chain and the guide rail. There were problems such as mixing oil into light foods.

  For this reason, the applicant of the present invention is to carry the food dough on the endless wire mesh belt that is looped between the driving roller and the driven roller and circulates, and on the peripheral surface of the driving roller, Teeth that mesh with the mesh of the wire mesh belt that is laid to run the wire mesh belt are provided, and the carrier side belt contacts the lower side of the carrier side belt that travels on the food dough to prevent the carrier side belt from being bent. The conveyance machine for foodstuff manufacturing apparatuses provided with the bending prevention member to which it does was proposed (refer patent document 3). When the drive roller is driven in this food manufacturing apparatus transport machine, the teeth provided on the peripheral surface mesh with the mesh of the mesh mesh belt and the mesh mesh belt travels. At this time, since the deflection preventing member is provided below the carrier side belt, the carrier side belt can convey the food dough without being bent. As a result, since the food dough can be stably conveyed without providing an endless chain, it is possible to reduce the size and cost, and to prevent the lubricating oil from being mixed into the food dough.

  However, when the metal mesh belt is driven by driving the driving roller, it may be shifted laterally. That is, when conveying rice cracker dough, a balance belt is used as the wire mesh belt because it is excellent in versatility, corrects meandering and offset, and is excellent in tensile strength. This balance belt is a combination of a right-handed spiral wire, a left-handed spiral wire, and a bent wire. . In other words, the tooth is positioned in the recess formed by the right-handed spiral wire or the left-handed spiral wire, but the tip (upper end) of the tooth is in contact with the right-handed spiral wire or the left-handed spiral wire. Since the balance belt is stretched over the drive roller so as to cover the teeth, the balance belt is lifted from the drive roller due to lateral movement of the balance belt during running, and the teeth and the balance belt are engaged.

  According to the present invention, when the driving roller is driven, the lateral slip prevention teeth provided on the peripheral surface are inserted into and engaged with the lateral slip prevention holes of the metal belt, so that the metal mesh belt is slightly lifted from the drive roller. However, since the travel is performed without releasing the engagement between the lateral slip prevention teeth and the wire mesh belt, the wire mesh belt travels reliably without being laterally displaced.

  In the wire mesh belt according to the present invention, it is preferable that the lateral slip prevention teeth are provided in one or more rows in the vicinity of both sides of the wire mesh belt. In the wire mesh belt according to the present invention, it is preferable that the wire mesh belt is a balance belt, and a part of a wire constituting the wire mesh belt is cut to form the lateral slip prevention hole. Further, in the wire mesh belt according to the present invention, the wire mesh belt is a balance belt formed by combining a right-handed spiral wire, a left-handed spiral wire, and a bent wire, and both sides of the wire mesh belt are made of the right-handed spiral wire. It is preferable that the end and the end of the bent wire are welded and the end of the left-handed spiral wire and the end of the bent wire are welded.

A transport machine for a food manufacturing apparatus for transporting, wherein teeth are provided on a peripheral surface of the drive roller or the drive roller and the driven roller so as to mesh with a mesh of the stretched wire mesh belt and run the wire mesh belt When the teeth mesh with the wire mesh belt, the teeth are provided with lateral slip prevention teeth that penetrate the wire mesh belt.

  According to this invention, when the drive roller is driven, the teeth provided on the peripheral surface mesh with the mesh of the wire mesh belt, and the wire mesh belt travels. At this time, since the metal mesh belt is meshed with the lateral slip prevention teeth penetrating the metal mesh belt, even if the metal mesh belt is slightly lifted from the drive roller, the mesh mesh belt runs without being disengaged. The wire mesh belt can be reliably traveled without being displaced laterally.

  In the food manufacturing apparatus transport machine according to the present invention, it is preferable that the lateral slip prevention teeth are provided on a peripheral surface of the driven roller. Moreover, in the food manufacturing apparatus transport machine according to the present invention, it is preferable that the lateral slip prevention teeth are arranged in one or more rows at least in the vicinity of both sides of the wire mesh belt.

Then, when the rotation driving device 50 is driven to drive the drive shaft 22 to rotate, the roller unit 20 (including the first roller unit 20a and the second roller unit 20b) is driven to rotate, and the first roller unit 20a is rotated. The lateral slip prevention teeth 8 mesh with the lateral slip prevention holes 47 of the wire mesh belt 4, and the engagement teeth 6 of the second roller portion 20 b mesh with the mesh 41 of the wire mesh belt 4 so that the wire mesh belt 4 circulates. Thus, when the wire mesh belt 4 travels, the toothed roller portion 30a rotates through the teeth 6 meshed with the mesh 41 of the wire mesh belt 4. As a result, the driven roller 3 including the toothed roller portion 30a rotates via the driven shaft 32, so that the wire mesh belt 4 is circulated without any deviation and without lateral displacement.

  That is, since the lateral slip prevention teeth 8 and the engaging teeth 6 are engaged with the lateral slip prevention holes 47 and the mesh 41 of the wire mesh belt 4, the wire mesh belt 4 circulates without deviation. Further, the lateral slip prevention teeth 8 are inserted into the lateral slip prevention holes 47 of the wire mesh belt 4, and the tip portion protrudes from the lateral slip prevention holes 47 (wire mesh belt 4), so that the wire mesh belt 4 is slightly lifted from the drive roller 2. Also, the engagement between the lateral slip prevention teeth 8 and the wire mesh belt 4 is not released. Further, since the lateral slip prevention teeth 8 are engaged with both sides of the wire mesh belt 4, the engagement between the lateral slip prevention teeth 8 and the wire mesh belt 4 is not released. Accordingly, the wire mesh belt 4 reliably circulates without being displaced laterally.

  The food dough is placed on the carrier side belt 4a while the wire mesh belt 4 is running. That is, the food dough is placed on the carrier side belt 4 a from the vicinity of the driven roller 3 and is conveyed in the direction of the driving roller 2 from the vicinity of the driven roller 3. At this time, since the food dough is guided by the guide member 9 from the vicinity of both sides of the carrier side belt 4a to the center side thereof, the food dough can be conveyed without dropping from the carrier side belt 4a.

  Further, when the food dough is conveyed, since the lower surface of the carrier side belt 4a contacts the deflection preventing member 7 and the carrier side belt 4a travels without being bent, the wire mesh belt 4 can be used for conveying the food dough. .

  Therefore, the wire mesh belt 4 and the food manufacturing apparatus transport machine 1 according to the present invention can move the wire mesh belt 4 in a circulating manner without causing a deviation and without causing a lateral shift, thereby stably conveying the food dough. Can be done.

  Further, when the deflection preventing member 7 is provided along the traveling direction of the wire mesh belt 4, the food dough can be stably conveyed. That is, for example, when the deflection preventing member 7 is provided in the width direction of the wire mesh belt 4, the wire mesh belt 4 bends between the deflection preventing members 7. Therefore, when the food dough passes through the portion, the food dough may move in the width direction of the wire mesh belt 4, for example. In other words, to put it in an extreme, the carrier side belt 4a travels in a wavy manner, and the food dough may not be stably conveyed. On the other hand, when the deflection preventing member 7 is provided along the traveling direction of the wire mesh belt 4, the traveling carrier side belt 4a hardly travels by wave meshing. Stable. In particular, when the food dough is a rice cracker, if the food dough moves on the belt during conveyance in the drying process, baking process, and seasoning process, the food dough may be unevenly dried or baked. Don't worry. Therefore, the conveyance machine 1 for food production apparatuses according to the present invention is particularly useful as a conveyance machine for food production apparatuses for producing confectionery such as rice crackers.

  The ends of the right-handed spiral wire 43 and the ends of the bent wire 45 on both sides of the wire mesh belt 4 are welded to form a connecting portion 48, and the end of the left-handed spiral wire 44 and the bent wire 45 are formed. When the connecting portion 48 is formed by welding the end portions of the wire mesh belt 4, the both sides of the wire mesh belt 4 cannot be unwound when the both sides of the wire mesh belt 4 circulate, so that the food dough can be stabilized. It can be reliably transported.

  Further, by providing the lateral slip prevention teeth 8 on the peripheral surface of the driven roller 3, the wire mesh belt 4 can be circulated without causing any further deviation and lateral displacement, and the food dough can be conveyed more stably. You can do it.

  As described above, the wire mesh belt and the food manufacturing apparatus transport machine according to the present invention are engaged even if the wire mesh belt is slightly lifted from the drive roller because the lateral slip prevention teeth are inserted through and engaged with the lateral slip prevention holes. Since the metal mesh belt can travel reliably without being displaced laterally, it can be used as a transport machine for food production equipment that produces confectionery such as rice crackers. It is preferably used.
