BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick delivery device that separates and supplies sticks piled up in bulk into a hopper one by one.

0002

2. Description of the Related Art Conventional stick delivery devices for feeding soft sticks such as cigarettes and filters one by one include devices as shown in FIGS. 4 and 5. The apparatus shown in FIG.
, 2 extend downward, a space 4 through which the rod-shaped object A can pass is formed between the lower ends of the vertical walls 2, 2 and the delivery surface 3, and a pusher 5 is arranged outside this space 4. will be established.

[0003] In the pusher 5, a piston rod 7 is moved in and out by the fluid sent into the cylinder 6, and when it is protruded, the tip of the piston rod 7 passes through the space 4. Inside the hopper, a scraping roller or scraping plate 9 with a non-circular outer circumferential surface is fixed to a swingable shaft 8, and a scraping roller or scraping plate 9 with a non-circular outer circumferential surface is fixed to the shaft 8, and a scraping roller or scraping plate 9 is fixed to the shaft 8, which is swingably provided. Shaked by the rocking motion of the scraping roller or the scraping plate 9, it is supplied falling downward without forming a bridge at the lower ends of the inclined walls 1, 1, passing between the vertical walls 2, 2 and entering the space 4. Each time the tip of the piston rod 7 passes through the space 4 after being supplied, the rod-shaped objects A located in the space 4 are sent out one by one to the opposite side of the pusher 5.

The device shown in FIG. 5 has a vertical plate 10 and an inclined plate 1.
1 is fixed to the rotating shaft 12 below the hopper having the
A rotating roller 14 having a plurality of grooves 13 on its outer peripheral surface is disposed, and an opening 15 through which the rod-shaped object A is sent out is formed between the lower end of the vertical plate 10 and the grooves 13 of the rotating roller 14. The rod-shaped object A that has fallen from the hopper under its own weight is accommodated in the groove 13 of the rotating roller 14 and sent out from the opening 15.

[0005]

Problem to be Solved by the Invention The rod-shaped object feeding device shown in FIG. 4 not only includes the pusher 5, but also includes a raking roller or raking plate 9 for preventing the rod-shaped object A from clogging, and a driving device thereof. This has the disadvantage of complicating the structure of the stick-feeding device, and if the stick A is soft like a rolled cigarette, the shreds will fall out from the rolled tobacco under the pressure of the roller or smoothing plate 9. However, there were problems such as inaccurate quality measurement of the rolled cigarettes supplied to the quality measuring machine.

[0006] In the rod-like object feeding device shown in FIG. 5, the rod-like object A
If the size of the groove 13 changes, there is the trouble of having to change the shape and dimensions of the concave groove 13, and there is a drawback that it cannot accommodate rod-shaped objects A that have slightly different sizes, such as cigarettes and filters. If A is soft like a rolled cigarette, the shreds will fall off the rolled cigarette when it receives the clamping force near the opening 15, resulting in the same problem regarding the quality of the rolled cigarette. The present invention aims to solve such problems, and provides a rod-shaped object feeding device that minimizes the pressure applied to the rod-shaped object A to prevent the notches from falling off as much as possible, and has a simple structure with a small number of drive devices. It is something to do.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the rod-shaped object feeding device of the present invention includes a vertical side wall erected substantially vertically at the side end of a supply stand, and a vertical side wall fixed to the vertical side wall. a partition plate having a supply opening at a lower part; and a slope plate movably provided on the supply table, and having an inclination angle that is substantially perpendicular to the vertical side wall and allows a rod-shaped object in contact with the inner wall surface to fall under its own weight. , a length regulating plate disposed with respect to the vertical side wall at an interval for accommodating the rod-shaped object, forming a hopper having a triangular vertical cross section, and a hinge provided at the lower end of the partition plate; A rocking plate that can swing outward from a position where the supply opening is closed is pivotally mounted, a spring is provided that biases the rocking plate in a direction to close the supply opening, and the supply stand A pusher was fixed to the top and the tip of the pusher reciprocated toward the supply opening.

[0008] The outline of the length regulating plate is formed to have approximately the same shape as the vertical cross-sectional shape of the hopper, and a length adjusting rod is movably inserted into a hole provided in the vertical side wall to adjust the length. The tip of the length adjusting rod is fixed to the length regulating plate, so that the dimensions of the hopper can be easily changed according to the length of the rod-shaped object.

[0009]

[Operation] In the rod-like object feeding device configured as described above, a large number of rod-like objects housed between the partition plate and the inclined plate move downward one by one due to their own weight, and the lowest rod-like object stops at the supply opening. . When the piston rod of the pusher moves forward, the rod-like object at the lowest end, which is lightly pushed by the piston rod, opens the rocking plate and is sent out. Since the rocking plate swings in response to a light force, the pressure applied to the rod-shaped object is small. When the pusher piston rod is retracted, the next rod stops at the feed opening.

[0010] When supplying rods of different lengths,
Move the length adjustment rod between the length regulation plate and the vertical side wall.
The rod-shaped object is adjusted to an interval where the rod-shaped object can be inserted and the position of the rod-shaped object is not disturbed in the longitudinal direction of the rod-shaped object. Further, when feeding rod-like objects with different diameters, the inclined plate is moved to adjust the distance between the inclined plate and the vertical side wall.

[0011]

[Embodiment] An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a vertical cross-sectional view of a rod-shaped object feeding device, and Fig. 2
shows a perspective view of the rod-shaped object feeding device. In the same figure,
A rectangular plate-shaped vertical side wall 16 is erected almost vertically on the edge of the supply table 19 , a substantially vertical partition plate 17 is fixed to one side of the vertical side wall 16 , and an inclined plate 18 extends over the supply table 19 . A rod-shaped object storage space is formed between the partition plate 17 and the inclined plate 18, which are movably provided and have a triangular longitudinal cross section. The inclined plate 18 has an inclination angle such that a rod-shaped object A such as a rolled cigarette or a filter in contact with the inner wall surface falls under its own weight, and a supply opening 20 is formed between the lower end of the vertical side wall 16 and the supply table 19.

A hinge 21 is provided at the lower end of the partition plate 17, and the upper end of the swing plate 22 is pivotally attached to the hinge 21, and a spring locking member 23 provided on the outer wall surface of the swing plate 22 and the vertical side wall 16 are connected to each other. A position where the rocking plate 22 closes the supply opening 20 when both ends of the spring 24 having a weak tensile force are locked to the outer wall surface of the spring 24 and the spring locking member 23 comes into contact with the edge of the vertical side wall 16. It is in. Therefore, the swing plate 22 can swing outward from the partition plate 17 from the position where the supply opening 20 is closed, and is biased in the direction to close the supply opening 20.

A boss portion 25 is provided protruding from the outer wall surface of the vertical side wall 16, and a length adjustment rod 27 is inserted into a hole 26 passing through the boss portion 25. The length adjusting rod 27 is movable along the hole 26, and a length regulating plate 28 is fixed to the tip protruding from the inner wall surface of the vertical side wall 16.

The contour shape of the length regulating plate 28 is similar to that of the partition plate 1.
It has almost the same shape as the triangular rod-shaped object storage space formed between the length regulating plate 28 and the vertical side wall 1.
6 and the inner wall surface can be adjusted according to the length of the rod-shaped object A.

A pusher 29 is fixed on a supply table 19 below the inclined plate 18. Pusher 29 is cylinder 30
and a piston rod 31, and when fluid such as air is supplied into the cylinder 30, the piston rod 31 moves in and out,
When the piston rod 31 protrudes, the tip of the piston rod 31 passes through the supply opening 20.

The operation of the rod-shaped object feeding device constructed as described above will be explained based on the operation diagrams shown in FIGS. 3(A) to 3(D). When a large number of rod-like objects A are accommodated between the partition plate 17 and the inclined plate 18, the many rod-like objects A sequentially move downward due to their own weight, and the lowest rod-like object A1 stops at the supply opening 20.

Next, the piston rod 31 of the pusher 29 protrudes, and the tip of the piston rod 31 hits the lowest rod-shaped object A1 (see FIG. 3(A)). When the piston rod 31 protrudes further, the tip of the piston rod 31 The rod-shaped object A1 at the lowest end moved, and the rocking plate 22 pushed by the rod-like object A1 at the lower end begins to open to the outside of the partition plate 17 (Fig. 3(B)
)reference).

Since the height dimension of the piston rod 31 is approximately equal to the diameter of the rod-like object A, when the piston rod 31 protrudes further, the rod-like object A2 located above the lowest end rod-like object A1 is placed on the upper surface of the piston rod 31. It will be done. Further, the lowermost rod-shaped object A1, which is lightly pushed by the piston rod 31, opens the rocking plate 22 and is sent out (see FIG. 3(C)).

Next, the piston rod 31 moves in the retracting direction (see FIG. 3(D)), and the rocking plate 22 is closed.
The rod-shaped object A2 placed on the top surface of the piston rod 31 falls from the piston rod 31, and a new rod-shaped object A1 at the bottom end
Thus, one cycle of feeding out the rod-shaped object is completed.

Since the rocking plate 22 swings in response to a light force, the pressure applied to the rod-shaped object A is small, so when the rod-shaped object is a rolled cigarette, there is an advantage that the shreds will not fall off the end surface of the rolled cigarette; When a rolled cigarette is fed to a quality measuring machine by the material feeding device, it is possible to accurately measure the quality of the rolled cigarette so that the cut pieces do not fall off the end surface of the rolled cigarette.

[0021] When feeding one type of rod-like object and sending out a rod-like object of a different length, the length adjusting rod 27 is moved to move between the length regulating plate 28 and the vertical side wall 16. The rod-like object can be inserted and the position of the rod-like object can be easily adjusted to an interval that does not disturb the longitudinal direction of the rod-like object.

[0022]

As the present invention is constructed as described above, it is possible to send out extremely soft rod-shaped objects such as rolled cigarettes and filters by only applying extremely small pressure. Therefore, when supplying rolled cigarettes to the quality measuring machine, there is no drop-off of the cigarettes, so the quality of the rolled cigarettes can be accurately measured.

Further, in the rod-shaped object feeding device of the present invention, the pusher is the only part that requires driving, and the structure of the rod-shaped object feeding device is extremely simple.
