[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an end portion of a belt conveyor for reducing the thickness of the belt conveyor, and more particularly to a structure of an end portion of a belt conveyor that conveys food and food ingredients.

[0002]

[Prior art]

 FIG. 4 is an explanatory view showing communication between two belt conveyors, and FIG. 5 is an explanatory view showing other communication between two belt conveyors.

As shown in FIG. 4, in the belt conveyor, in order to transfer the transferred object to the succeeding belt conveyor, as shown in FIG. 4, the succeeding belt is located below the downstream end of the preceding belt conveyor. It is arranged near the upstream end of the conveyor, and when the transported object is dropped and transferred from the downstream end of the destination, as shown in Fig. 5, the downstream end of the preceding belt conveyor and the upstream end of the following belt conveyor. There is a case where the conveyed objects discharged from the downstream end of the preceding belt conveyor are transferred to the upstream end of the following belt conveyor by abutting against each other.

By the way, in the case where the material to be conveyed has a rollable shape such as a kneaded product and its material, a soft material, or a polygonal shape such as tofu which easily holds the corners. In the connection of the above-mentioned two conveyors, since the conveyor tip diameter is large, it is not possible to smoothly transfer the transferred objects, which may disturb the alignment of the transferred objects or deform the transferred objects. was there.

In a belt conveyor, it has been known that when transferring a conveyed object to a succeeding belt conveyor, it is possible to obtain a smooth transfer when the diameter of the leading end roller of the conveyor is as small as possible.

[0006]

[Problems to be solved by the device]

 However, if the tip diameter is made smaller, it will add a great deal to the driving of the belt, and the size of the tip roller depends on the bearing diameter put in the roller. The diameter of the stainless bearing is about 20 mm at the smallest, so the roller diameter including this bearing is about 25 mm.

Further, in consideration of the washability, there is a drawback that the washability is poor with a complex bearing such as a stainless steel bearing, and the washability is low with a small bearing, and the washability becomes lower as the size is reduced. This is a serious problem for belt conveyors that carry food and food ingredients.

It is an object of the present invention to obtain a belt conveyor having an end structure capable of reducing the thickness of the belt conveyor that conveys food and food ingredients.

[0009]

[Means for Solving the Problems]

 In the belt conveyor according to the present invention, the wide endless annular conveyor belt is circulated between the belt feed rollers installed at both ends, and the object to be conveyed is placed on the conveyor belt. At least one end of the belt conveyor is a round bar shape that rotates by contacting the conveyor belt with a roller slide receiver having a recess along the substantially semi-peripheral shape of the belt feed roller. The belt feed roller is rotatably housed.

In the belt conveyor according to the present invention as defined in claim 2, in the belt conveyor according to claim 1, a cutting means for separating an object to be conveyed from above the conveyor belt in a width direction of the conveyor belt at one end of the belt conveyor. It is a bridge line installed.

[0011]

[Action]

 In the present invention, at least one end of the belt conveyor rotates a round bar-shaped belt feed roller that rotates by contacting the conveyor belt with a roller slide receiver having a recess along the substantially semi-peripheral shape of the belt feed roller. Since it is movably housed, the diameter of the round bar-shaped belt feed roller can be made extremely small, such as 3 mmφ, 5 mmφ, and 7 mmφ.

Moreover, since the round bar-shaped belt feed roller is rotatably accommodated in the roller slide receiver, the structure that can withstand the bending due to the tensile strength due to the tension of the conveyor belt caused by the decrease in the diameter of the belt feed roller is provided. Has become.

Therefore, the diameter of the round bar-shaped belt feed roller can be made very small, such as 3 mmφ, 5 mmφ, 7 mmφ, and the thickness of the belt conveyor is made to be about the diameter of the belt feed roller. Thus, it becomes possible to smoothly convey a soft transported object such as a kneaded product and its material or an angular transported object such as tofu.

[0014] Furthermore, since the round bar-shaped belt feed roller is rotatably housed in the roller slide receiver, maintenance work is facilitated, and cleaning work is facilitated especially on a belt conveyor that conveys food and food materials. Becomes

In addition, if a separating line is installed at one end of the belt conveyor in the width direction of the conveyor belt to separate the object to be conveyed from the conveyor belt, viscous products can be well separated.

【Example】

 1 is a perspective view showing a configuration of an embodiment of the present invention, FIG. 2 is an exploded perspective view of a main part of FIG. 1, and FIG. 3 is an explanatory diagram of another main part of FIG. As shown in the figure, there is a belt conveyor (1) which circulates a wide endless annular conveyor belt (3) on a belt support plate (2) having a plate thickness of 5 mm.

At the end of the belt support plate (2), there is provided a roller slide receiver (6) having a concave portion (5) having a curved surface that follows substantially the semi-peripheral shape of the belt feed roller (4), A 5 mmφ round bar belt feed roller (4) is housed in the recess (5) of the roller slide receiver (6).

The concave portion (5) is coated with a lubricating oil or uses a support plate (2) made of a material having a good sliding property so that the belt feeding roller (4) can smoothly rotate. In order to obtain a smoother rotation of the belt feed roller (4), the surface treatment of silicon resin or the like should be performed on the abutting portion of the recess (5) and the belt feeding roller (4) or one of the abutting portions. May be given.

At both ends of the belt feed roller (4), a roller retainer (7) is fixed to the side wall of the belt support plate (2) with fine adjustment so that the roller (4) does not separate from the recess (5). There is. Near the axis of the roller (4) of the roller retainer (7), a piano wire (8) that separates the object to be conveyed from above the conveyor belt (3) is laid across the width of the conveyor belt (3). .

As described above, the round bar-shaped belt feed roller (4) is rotated around the roller slide receiver (6) having the concave portion (5) having the curved surface that follows the semi-peripheral shape of the belt feed roller (4). Since it is housed in motion, the diameter of the belt feed roller (4) can be made very small, and at least the end portion of the belt conveyor (1) can be thinned accordingly.

Therefore, when the transferred object is transferred to the succeeding belt conveyor, smooth transfer is possible, and for example, a soft transferred object such as a kneaded product and its material, or a corner such as tofu. It becomes possible to smoothly carry an object to be transferred without impairing the shape of the object to be transferred.

In the above-mentioned embodiment, the belt feed roller (4) has a diameter of 5 mmφ, but it may have a very small diameter such as 3 mmφ or 7 mmφ. Further, the belt feeding roller (4) may be a round bar, and a circular tube may be used without any problem.

[Effect of device]

 As described above, according to the present invention, at least one end of the belt conveyer is a round bar-shaped belt feed that rotates by contacting the conveyor belt with a roller slide receiver having a recess along the substantially semi-peripheral shape of the belt feed roller. Since the roller is rotatably housed, the diameter of the round bar-shaped belt feed roller can be made extremely small, such as 3 mmφ, 5 mmφ, 7 mmφ.

Moreover, since the round bar-shaped belt feed roller is rotatably accommodated in the roller slide receiver, the structure that can withstand the bending due to the tensile strength due to the tension of the conveyor belt caused by the decrease in the diameter of the belt feed roller is provided. Has become.

Therefore, the diameter of the round bar-shaped belt feeding roller can be made extremely small, such as 3 mmφ, 5 mmφ, and 7 mmφ, and the thickness of the belt conveyor is set to be about the diameter of the belt feeding roller. Thus, it becomes possible to smoothly carry soft objects to be conveyed such as kneaded products and their materials, and objects to be conveyed having corners such as tofu.

Further, since the round bar-shaped belt feed roller is rotatably housed in the roller slide receiver, the maintenance work is facilitated, and particularly the cleaning work is facilitated in the belt conveyor that conveys food and food materials. Becomes

In addition, if a separation line is installed at one end of the belt conveyor in the width direction of the conveyor belt to separate the object to be conveyed from the conveyor belt, viscous products can be well separated. There is.
