(Prior Art) A rod-like object supply device supplies a rod-like object to a supply hopper that accommodates the rod-like object.

An example of the conventional device will be explained with reference to FIG. 2. In the figure, 13 is a box distribution mechanism, 14 is a loading mechanism, A is a filter plug, and B ₁ , B ₂ , and B ₃ are filter plugs A.
It is a storage box that stores. The storage box may be a metal tray or a cardboard box, and the opening on the top surface may be open from the beginning or may be opened by opening the top cover.

A storage box loading table 9 is provided above the box distribution mechanism 13. The box distributing mechanism 13 inverts the supplied storage box B ₁ into an inverted shape, and the carrying mechanism 1
Reference numeral 4 carries the inverted storage box B ₁ to the storage box loading table 9 with the bottom opening of the inverted storage box B ₁ closed.

A first belt conveyor 4' provided on a machine frame 15 installed at a position higher than the floor is connected to the unloading end side of the storage box loading table 9, and a pusher is provided above the storage box loading table 9. A belt conveyor 10 having a belt conveyor 11 is provided.

The storage box B ₁ placed on the storage box carry-in table 9 is transferred to the pusher 11 and carried to the carry-in side of the first belt conveyor 4' (the position of the storage box B ₂ ).

Storage boxes are placed on both sides of the first belt conveyor 4'.
In addition to providing side plates 8, 8 for guiding B ₂ and B ₃ ,
A box unloading mechanism 12 is provided on the discharge side of the first belt conveyor 4'.

The box lifting mechanism 12 lifts the storage box _B3 and
Only the rod-shaped object A remains on the belt conveyor 4'.

A second belt conveyor 5' is connected to the discharge end of the first belt conveyor 4' at a predetermined interval, and forms an entrance 3' of the supply hopper 1'.

The supply hopper 1' accommodates a rod-shaped object, and is arranged between frame plates 1a' and 1 at intervals approximately equal to the length of the rod-shaped object.
b' is arranged between the frame plates 1a', 1b', and guide plates 1c',
1d' are arranged in an approximately eight-figure shape.

a groove wheel 2a' forming the bottom of the supply hopper 1';
2a'... are provided rotatably, one rod-shaped object is fitted and stored in each groove of the groove wheels 2a', 2a'..., and the rod-shaped object A is delivered from the supply hopper 1'. It will be done.

The first belt conveyor 4' is disposed such that its discharge end is close to the inlet 3' of the supply hopper 1', and carries the rod-shaped object into the inlet 3'.

The second belt conveyor 5' has an inlet end thereof close to the inlet 3' of the hopper 1' and is disposed continuously at a distance from the first belt conveyor 4',
The rod-shaped object is conveyed to another supply hopper (not shown) or the like. The frame plates 7', 7' are vertically provided on both sides of the first and second belt conveyors 4', 5', respectively, and are continuous with the side plates 8, 8.

(Problem to be Solved by the Invention) The conventional feeding device has a first belt conveyor 4′.
Since the second belt conveyor 5' and the second belt conveyor 5' are at the same height, the amount of stick-like objects accumulated directly above the carry-in port 3' is small. Therefore, when a large amount of rod-shaped objects are supplied from the supply hopper 1', the upper surface formed by the rod-shaped objects A forms a valley, and the rod-shaped objects roll down from the top of the valley to the bottom and become diagonal. There is a risk that if the stick is slanted, it will not be dispensed correctly.

Moreover, the upper surface of the rod-shaped object conveyed to the second belt conveyor 5 also has an irregular wave shape, and the amount of conveyance per unit time is not constant, so that stable supply is not possible. In addition, there was a risk that the rod-shaped object would roll down from above the waves to below it and become slanted during conveyance.

The present invention has been made to solve the above-mentioned problems, and its purpose is to have a large amount of rod-like objects stored just above the opening on the top surface of the hopper, and to have a flat upper surface where the rod-like objects are formed. To provide a feeding device for rod-like objects that does not cause problems such as rolling down.

(Means for Solving the Problems) The present invention has a configuration in which a plurality of belt conveyors for conveying sticks in a pile are arranged in a row at predetermined intervals, and a supply hopper is installed between each conveyor. In a rod-shaped material supply device that includes a supply hopper that forms a loading port and that sequentially drops the rod-shaped objects below the loading port, the discharge end of the first belt conveyor is arranged to be close to the loading port of the first supply hopper. A first belt conveyor is provided, a second belt conveyor is provided lower than the first belt conveyor with the inlet of the first supply hopper in between, and a blocking plate is provided at an appropriate interval above the inlet end of the second belt conveyor. It is characterized by being installed vertically.

(Function) With the above configuration, a step is created between the first belt conveyor and the second belt conveyor, so that the amount of rod-shaped objects stored by the step increases. Moreover, since rod-like objects do not flow behind the blocking plate, rod-like objects can be reliably stored in the stepped portion. Further, the lower end of the blocking plate flattens the upper surface of the rod-shaped object conveyed by the second belt conveyor.

(Embodiment) An embodiment of the present invention will be described with reference to FIG. 1. A hopper 1 accommodates a rod-shaped object, and frame plates 1a and 1b are arranged at intervals approximately equal to the length of the rod-shaped object,
Guide plates 1c and 1d are arranged in a substantially eight-shape pattern between the frame plates 1a and 1b.

A vertical wall portion 1 is provided on the upper part of each of the guide plates 1c and 1d.
e and 1f, respectively, so that the vertical wall portion 1e of the carry-in guide plate 1c is higher than the vertical wall portion 1f of the carry-out guide plate 1d.

The frame plates 1a, 1b and the vertical walls 1e, 1f of the guide plates 1c, 1d constitute an inlet 3 of the supply hopper 1, through which rod-shaped objects are carried in.

a groove wheel 2a constituting the bottom of the supply hopper 1;
2a... are provided rotatably, one rod-shaped object is fitted and stored in each groove of the groove wheels 2a, 2a..., and the feeding device 2 is configured to feed the rod-shaped object A from the supply hopper 1. .

Upper frame plates 7, 7 are connected to the upper parts of the frame plates 1a, 1b, and constitute a storage section for rod-shaped objects.

The first belt conveyor 4 is provided so that the carry-out end of the first belt conveyor 4 is close to the carry-in side vertical wall 1e of the carry-in port 3, and the carry-in end of the second belt conveyor 5 is close to the carry-in side vertical wall 1f. A second belt conveyor 5 is provided so as to.

The first belt conveyor 4 is a belt conveyor having a width approximately equal to the length of the rod-shaped object, and carries the rod-shaped object into the entrance 3 of the supply hopper 1.

The second belt conveyor 5 is the first belt conveyor 4
This is a belt conveyor having the same configuration as the one shown in FIG. 1, and carries out the rod-shaped objects stored directly above the inlet 3 of the supply hopper 1 to another supply hopper (not shown).

Side plates 8, 8 are provided on each side of the first and second belt conveyors 4, 5 so as to be continuous with the upper frame plates 7, 7, respectively.
to guide the rod-shaped object being conveyed.

A blocking plate 6 is vertically provided above the carry-in end of the second belt conveyor 5 at appropriate intervals.

The blocking plate 6 is a plate material having the same width as the second belt conveyor 5, and a reinforcing plate 6a is provided on the back side thereof. The blocking plate 6 stores the rod-shaped objects directly above the upper surface opening 3, and also makes the height of the rod-shaped objects conveyed by the second belt conveyor 5 uniform.

(Effects of the Invention) As described above, the present invention comprises arranging a plurality of belt conveyors in a row at predetermined intervals for conveying stick-like objects in a piled manner, and forming an inlet for a supply hopper between each conveyor. In addition, in the rod-like object supplying device provided with a supply hopper for sequentially dropping the rod-like objects under the carrying-in port, the first belt conveyor is arranged so that the carrying-out end of the first belt conveyor is close to the carrying-in port of the first supply hopper. Since the second belt conveyor is installed lower than the first belt conveyor with the entrance of the first supply hopper in between, a step is created between the first belt conveyor and the second belt conveyor. In addition to increasing the amount of objects stored, blocking plates are installed vertically at appropriate intervals above the inlet end of the second belt conveyor, and rod-shaped objects do not flow behind the blocking plate, so that it is possible to prevent rod-like objects from flowing into the stepped portion. Stick-shaped objects can be stored reliably. Therefore, since a large amount of rod-like objects can be stored directly above the delivery entrance of the supply hopper, the rod-like objects can be stably fed into the supply hopper, and the surface of the rod-like objects is almost flat, so there is no risk that the rod-like objects will roll and become slanted. There is no

Furthermore, since the lower end of the blocking plate flattens the upper surface of the rod-shaped object conveyed by the second belt conveyor, the conveyance condition is stabilized and the supply amount is constant.

By doing so, we will reach our intended purpose.
