2. Description of the Related Art Conventionally, as this type, for example, Japanese Patent Publication No.
As disclosed in Japanese Unexamined Patent Publication No. 6-31947, protrusions are provided on the outer peripheral surfaces of both belts at regular intervals in the conveying direction of the rod-shaped object, and the protrusions are alternately arranged in the conveying direction between the facing portions of both belts. By projecting them and moving both belt facing parts upward and pressing each protrusion against the aligned rod-shaped assembly, a bridge state between the rod-shaped objects is created between the staggered protrusions and the downward displacement occurs. Some are transported upward without doing so.

[0003]

However, in such a conventional start-up conveyor, when the rod-shaped aggregates are sandwiched by both belts, the protrusions bite into the rod-shaped aggregates. There is a problem in that the bar-shaped object on which the projection abuts is easily damaged, and particularly when the bar-shaped object is a cigarette, the bar-shaped object is damaged and the commercial value is significantly reduced.

In view of the above conventional circumstances, it is an object of the present invention to form a bridged state between rod-like objects without disposing a protrusion between the opposing portions of both belts.

[0005]

In order to solve the above-mentioned problems, the technical means to be taken by the present invention is to form both belts by elastically deformable cushioning materials, and at least one of the opposing portions of these belts is It is characterized in that a plurality of elastic bodies are arranged inside in the conveying direction of the rod-shaped article, and the facing portion is pressed toward the facing portion of the other belt by an appropriate pressure.

[0006]

According to the above technical means of the present invention, an assembly of rod-shaped objects is sandwiched between the facing portions of both belts, and at least one facing portion of each elastic member is pressed toward the other facing portion, By applying an appropriate pressure to both of these facing portions toward the rod-shaped object, at least one of the facing portions that is elastically deformable corresponding to the outer shape of the aggregate of rod-shaped objects is bent and deformed, and the surfaces of both facing portions are The rolling friction increases due to compression deformation and engagement over the entire length in the carrying direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIG. 1, the belts 1 and 2 are arranged in a slanted manner, a part of each of them is opposed substantially in parallel, and the belt 1 is bent along the inner surface of an opposed portion 1a. The band 3 is arranged, the fixing piece 5 is arranged substantially parallel to the inside of the bending band 3 via the elastic bodies 4, ... And the straight guide which cannot be bent along the inside of the facing portion 2a of the other belt 2. 6 is fixedly arranged.

Both belts 1 and 2 are drive pulleys 1 respectively.
b, 2b and the driven pulleys 1c, 2c are wound so as to be bendable, and the driving pulleys 1b, 2b are moved at a constant speed upward by the rotation of the drive pulleys 1b, 2b, and are formed of an elastically deformable cushion material. In the case of this embodiment, both belts 1,
A bendable core material is arranged on the inner peripheral surface of 2, and a sponge is fixed to the outer surface thereof, and a bendable protective film is fixed to the outer peripheral surface thereof.

The bending band 3 is made of a bendable material and is formed into a strip plate shape having substantially the same width dimension as the one belt 1.
a is provided over substantially the entire length in the transport direction, and cuts 3a ... Are alternately formed in the transport direction from both of the long sides thereof in the direction orthogonal to the transport direction, and the dividing portions between the cuts 3a are formed. 3b ... Can be bent independently, and a plurality of elastic bodies 4 such as compression springs are arranged in the conveying direction from the divided portions 3b ... to the fixed piece 5, respectively, and the elastic bodies 4 ... The bending band 3 is pressed against the facing portion 2a of the other belt 2 with an appropriate pressure.

The above-mentioned appropriate pressure means that the one opposing portion 1a is bent and deformed in accordance with the outer shape A1 of the assembly of the rod-shaped objects A sandwiched between the opposing portions 1a and 2a, and both belts 1 and 2 are bent. The opposing portions 1a, 2a of the above are pressed against the outer shape A1 of the aggregate of the rod-shaped objects A to compress and deform these surfaces, respectively. In the case of this embodiment, the tips of the elastic bodies 4 are fixed to the base ends of the cuts 3a.

At the entrances of the two belts 1 and 2, that is, at the lower ends of the opposing portions 1a and 2a, a horizontal conveyor 7 is connected to the horizontal conveyor 7 which is continuous with the belt-like material feeding portion of a cigarette making machine or the like. By the operation of the horizontal conveyor 7, the assembly of the rod-shaped articles A carried in from the rod-shaped article supply section is horizontally conveyed toward the entrances of the belts 1 and 2 and at the same time, for example, a guide plate pivotally supported swingably. After lowering the stack height of the aggregate of rod-shaped objects A in 8, the horizontal portion 1d of one belt 1 is
It is sandwiched between the belt and the horizontal conveyor 7 to make the pile height substantially equal, and then the belts 1 and 2 are carried out to the entrance.

Next, the operation of the rising conveyor will be described.

First, the drive pulleys 1b and 2b are rotated so that one opposing portion 1a moves upward along the bending band 3 and the other opposing portion 2a moves upward along the linear guide 6 at a constant speed. When the aggregates of the rod-shaped objects A are conveyed to the entrances of the belts 1 and 2 by the operation of the horizontal conveyor 7 with the deposition heights thereof being substantially equal, the aggregates of the rod-shaped objects A face each other. From the lower ends of the portions 1a and 2a, the upper portions move into the space between them.

At this time, one facing portion 1a is made up of the elastic members 4 ...
The other belt 2 through the divided portions 3b ...
Is pressed by an appropriate pressure toward the facing portion 2a of the
The facing portion 1a is bent and deformed corresponding to the outer shape A1 of the assembly of the rod-shaped objects A facing each other.

At the same time, since the other facing portion 2a hits the linear guide 6 and does not move inward from it,
The surfaces of the opposing portions 1a and 2a are pressed against the outer shape A1 of the assembly of the rod-shaped objects A facing them by the elastic bodies 4, ...

However, the aggregate of the rod-shaped materials A is not compressed by the elastic bodies 4, ...

Therefore, the two opposed portions 1a and 2a which have been pressed and deformed
The rolling friction of each rod-shaped article A engaged with the surface of the rod-shaped article A is increased, and the aggregate of the rod-shaped articles A is not displaced downward with the upward movement of the facing portions 1a and 2a, and the rod-shaped articles A are bridged with each other. A state is created and transported upwards.

After that, when the aggregate of the rod-shaped objects A is conveyed upward, the bending portion 1e of the one facing portion 1a also moves upward in conjunction with this, and along with this, the divided portion of the bending band 3 is also moved. 3b ... sequentially move in and out due to the expansion and contraction of the elastic bodies 4 ..., and move while maintaining the shape of the bent portion 1e of the one facing portion 1a, whereby the alignment state of the aggregate of the rod-shaped objects A is not disturbed. .

In the embodiment shown above, the two belts 1 and 2 are arranged in a slanting manner and a part of each of them is made to face each other substantially in parallel, but the slanting angle is not limited to that shown in the drawing, and the two belts , 2 may be inclined in a state close to vertical or arranged vertically.

Further, the elastic members 4 are disposed only on the facing portion 1a of the one belt 1 via the bending band 3, but the invention is not limited to this, and the facing portions 1a and 2a of the two belts 1 and 2 are respectively provided. The elastic bodies 4 are arranged via the bending band 3, or the ends of the elastic bodies 4 are directly supported in a state of being immovably supported without being affected by the movement of the belts 1 and 2 without the bending band 3. You may make it contact.

[0022]

Since the present invention has the above-mentioned structure, it has the following advantages.

1. An assembly of rod-shaped objects is sandwiched between opposed portions of both belts, and at least one opposed portion is pressed toward the other opposed portion by each elastic body, and an appropriate pressure is applied to these opposed portions toward the rod-shaped objects. As a result, at least one opposing portion that is elastically deformable in accordance with the outer shape of the aggregate of rod-shaped objects is bent and deformed, and the surfaces of both opposed portions are respectively compressed and deformed over the entire length in the transport direction and engaged, Since the rolling friction of the rods becomes large, the rods can be bridged with each other without disposing the protrusions between the opposing portions of the belts.

Therefore, when the rod-shaped aggregate is held by both belts, compared with the conventional one that bites into the rod-shaped aggregate in which the projections are aligned, the rod-shaped one is particularly safe without damaging a cigarette. It can be transported and the product value can be maintained.
