[Problems to be solved by the device]

 By the way, in the above-described cooling net conveyor device according to the prior art, since the net belt 6 is only driven by the drive pulley 3 by utilizing the frictional force of the rubber lining 3C, the weight of the molding die 11 is reduced. If it becomes large, there is a problem that slippage occurs between the drive pulley 3 and the net-shaped belt 6, and the rubber lining 3C of the drive pulley 3 is quickly worn.

Further, in order to solve the above-mentioned problem, like the other conventional technique shown in FIG. 5, the large diameter portion 3A of the drive pulley 3 is provided with sprockets 12 (only one is shown) at both ends in the axial direction. A belt-shaped belt 6 is provided with chains 13 and 13 that mesh with the respective sprockets 12 at both ends in the width direction to prevent the drive pulley 3 and the belt-shaped belt 6 from slipping. Has been. However, in this case, the cost is increased because the chains 13 and 13 are attached to the net-shaped belt 6, and since it is necessary to lubricate the chains 13 and 13, there is a problem that oil easily adheres to the transported object. is there.

The present invention has been made in view of the above-mentioned problems of the prior art. The present invention can prevent slippage between the drive pulley and the net belt, and does not require work such as lubrication. It is an object of the present invention to provide a cooling net conveyor device that can be used in the above.

[Means for solving the problem]

 In order to solve the above problems, the feature of the configuration adopted by the present invention is that a plurality of engaging projections that engage with each mesh of the net-shaped belt are provided at predetermined intervals on the outer periphery of the drive pulley. ..

[0019]

[Action]

 With the above configuration, the engagement protrusions of the drive pulley can be engaged with the meshes of the net belt to prevent slippage between the drive pulley and the net belt.

[0020]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. It should be noted that the same components as those of the above-described conventional technique are designated by the same reference numerals and the description thereof will be omitted.

In the figure, reference numeral 21 denotes a drive pulley used in this embodiment. The drive pulley 21 is substantially the same as the drive pulley 3 described in the prior art, and has a large diameter portion 21A formed in a substantially cylindrical shape, The drive pulley 21 has a plurality of engagements at predetermined intervals in the circumferential direction and the axial direction on the outer peripheral surface of the large diameter portion 21A, although the drive pulley 21 has a small diameter rotating shaft 21B protruding from the center of the large diameter portion 21A. Mating protrusions 21C, 21C, ... Are provided.

Here, each of the engagement protrusions 21C is formed in a short columnar shape, the outer diameter of which is smaller than the mesh 6B of the net belt 6, and the base end side of each of the engagement protrusions 21C is planted on the outer peripheral side of the large diameter portion 21A. It is set up. Further, as shown in FIG. 2, each engaging projection 21C is formed so that the projection size on the front end side is equal to or less than the thickness of the net belt 6.

The engagement protrusions 21C are arranged in the axial direction of the large diameter portion 21A at predetermined intervals, for example, five, and are arranged at intervals of 90 degrees in the circumferential direction of the large diameter portion 21A. On the other hand, the large-diameter portion 21A of the drive pulley 21 has the large-diameter portion 21A of the large-diameter portion 21A based on the distance between the meshes 6B so that the engagement protrusions 21C are surely engaged with the meshes 6B of the net belt 6. The outer diameter is fixed.

However, in this embodiment, the large diameter portion 21A of the drive pulley 21 is provided with a plurality of engaging projections 21C that engage with the meshes 6B of the net belt 6 at regular intervals in the circumferential and axial directions. Therefore, when the drive pulley 21 is rotationally driven in the arrow A direction by the electric motor 2, the engagement protrusions 21C provided on the outer circumference of the large diameter portion 21B of the drive pulley 21 are moved to the large diameter portion 21A as shown in FIG. In the circumferential direction, the mesh 6B of the net belt 6 continues to be successively engaged at three places, for example, 90 degrees apart, and the net belt 6 slides on the large diameter portion 21A of the drive pulley 21. It can be driven without.

Therefore, according to the present embodiment, even when the weight of the molding die 11 is large, it is possible to effectively prevent the slippage between the drive pulley 21 and the net-shaped belt 6, and the drive pulley 21 It is possible to solve the problem that abrasion occurs between the large diameter portion 21A and the net belt 6. Further, unlike the other prior art shown in FIG. 5, it is not necessary to provide the sprocket 12, the chain 13 and the like, the structure can be simplified, and the lubrication is not necessary, so that the cost can be reduced.

It should be noted that, in the above-described embodiment, each engaging projection 21C provided on the drive pulley 21 is described as being formed in a short cylindrical shape, but the present invention is not limited to this, and each engaging projection 21C is, for example, a conical shape. It may be formed by using a tapered pin having a shape.

Further, in the above-described embodiment, the engaging projections 21C are described as being spaced apart by 90 degrees in the circumferential direction of the large-diameter portion 21A of the drive pulley 21 and arranging five in the axial direction. The engagement protrusions 21C may be provided in the circumferential direction of the large diameter portion 21A at intervals of, for example, 180 degrees, and the arrangement and number of the engagement protrusions 21C are determined by the size of the large diameter portion 21A and the mesh 6B of the net-shaped belt 6. It may be changed according to the shape or the like.

[Effect of the device]

 As described in detail above, according to the present invention, since the plurality of engaging protrusions that engage with each mesh of the net belt are provided at predetermined intervals on the outer periphery of the drive pulley, the engaging protrusions of the drive pulley are connected to the net. The net-like belt can be driven by engaging with each mesh of the belt-like belt, and slipping between the drive pulley and the net-like belt can be prevented to enhance the carrying capacity.

In addition, since the device has a simple structure that does not use a chain or a sprocket, the device can be manufactured at a low cost, and no oiling is required. Therefore, like foods and cosmetics, oil adhesion is hygienic and aesthetically friendly. Therefore, it is possible to provide a cooling net conveyor device suitable for carrying undesired articles.
