Description

[Detailed Description of the Invention] <Industrial Application Field of the Invention> The present invention relates to a rod-shaped product filling device used for filling a predetermined amount of rod-shaped products such as confectionery in an aligned state into a container or the like.

<Prior art> In recent years, stick-shaped sweets have been manufactured for ease of eating, but when packing such stick-shaped sweets into bags, trays, etc., packing them in a messy manner not only spoils the aesthetics but also causes problems. If the stick-shaped confectionery does not fit into a bag or tray of a predetermined size, or if the stick-shaped confectionery is crisscrossed with each other, it becomes easy to break.

For this reason, in the past, bar-shaped sweets sent from the production line or weighing line on a conveyor, etc., had to be manually aligned and packed. After manually weighing the trays to adjust excess or deficiency, or if the trays have already been weighed, the packaging process is carried out as is.

<Problems to be solved by the present invention> However, if the stick-shaped articles are manually aligned and packed into bags as described above, the work efficiency is extremely low, and furthermore, work errors may cause product failure. There were problems with unstable quality and unhygienic conditions.

As a technique for solving this problem, for example, Japanese Utility Model Application No. 49-27436 discloses that after aligning the orientation of rod-shaped articles housed in a hopper device having a triangular cross section by vibrating the side wall of the hopper device, A technique is shown for opening the sidewall and ejecting the rod-shaped article.

However, with this technique, when a large number of rod-shaped articles are housed in the hopper device at once, it is not possible to align the entire orientation of the articles unless large vibrations are applied for a long period of time.

In addition, JP-A No. 57-9618 discloses a vibrating conveyance system in which a hopper containing rod-shaped articles such as dried noodles is vibrated in an almost horizontal direction, and the rod-shaped articles are sent out horizontally from the bottom in a state that they are arranged little by little. However, since this technique uses vibration to perform alignment and conveyance, it is not possible to discharge a plurality of rod-shaped articles all at once in an aligned state in a short period of time.

The present invention has been made to solve such problems, and an object of the present invention is to provide a rod-shaped article filling device that can efficiently fill a container or the like with a large amount of rod-shaped articles in an aligned state.

<Means for solving the above-mentioned problems> In order to solve the above-mentioned problems, the rod-shaped article filling device of the present invention includes: a hollow rectangular column-shaped casing with openings at the top and bottom; a partition plate which partitions the upper half of the casing into two falling passages; and a partition plate which is movable horizontally into and out of the partition plate from two inner walls of the casing facing the partition plate. The rod-shaped article supplied from above is received on the upper surface with the front end in contact with the partition plate and the upper surface of the falling passage is closed, and the front end is separated from the partition plate to close the upper surface of the falling passage. a pair of shutters that open the top surface and allow rod-shaped articles on the top surface to fall into the dropping passage; and a pair of shutters provided below the pair of shutters, each of which has its lower end abutted against the lower part of the partition plate in an inclined state. The lower surface of the falling path is closed to receive the rod-shaped article falling from above, and after the rod-shaped article vibrates parallel to the partition plate, the lower end part moves away from the lower part of the partition plate. a pair of vibrating gates that rotate to drop the rod-shaped articles downward; and a pair of vibrating gates provided below the pair of vibrating gates and mutually disposed below the partition plate so as to close the bottom surface of the housing. A pair of discharge gates are provided, the lower ends of which are brought into contact with each other to receive the rod-shaped article from above, and the lower ends are rotated in a direction in which they are separated from each other to discharge the rod-shaped article downward. .

<Function> With this structure, in the rod-shaped article filling device of the present invention, the rod-shaped articles fed from above onto the pair of shutters are divided into two falling paths when both shutters are opened, and fall, causing each vibration. They are housed between the gate and the partition plate, and are aligned in the same direction by the vibration of the vibrating gate, and when both vibrating gates are opened, they are gathered on a pair of discharge gates, and when the discharge gate is opened, the directions are aligned. It is discharged.

<Embodiment of the present invention> (Figs. 1 to 4) An embodiment of the present invention will be described below based on the drawings.

This embodiment is provided at the lower part of a combination weighing device, and is formed in order to fill a packaging tray with the stick-shaped confectionery that is weighed and discharged by the combination weighing device in an aligned state.

The shutters 20 and 25 are driven by air cylinders 23 and 28 supported via mounting plates 21 and 26 on both sides of the side wall facing the partition plate 12, and move horizontally forward and backward into the fall paths L and R. open and close the entrances at the same time.

A pair of vibrating gates 30 and 35 are symmetrically formed below the shutters 20 and 25.

The vibration gates 30, 35 have free ends 30a, 35a.
The lower surface of each falling passage is closed by bringing the side into contact with the partition plate 12, and the falling passage is opened by rotating downward about the rotation shafts 31 and 36.

Further, the vibrating gates 30 and 35 are formed to vibrate in the closed state, and the irregularities of the rod-shaped articles are corrected by this vibration.

Opening/closing and vibration of the vibrating gates 30 and 35 are performed by a drive device on the back side of the rod-shaped article filling device 10. FIG. 3 is a diagram schematically showing this mechanism.

In FIG. 3, the rotation shafts 31 and 36 of the vibrating gates 30 and 35 are fixed to arm portions 31a and 36a extending in vertically opposite directions, and both arm portions 31 and 36 are

The center portion 42a is rotatably connected to one end side 42b of a link member 42 connected to the lower end side (the other end side 42c of the link member 42 is fixed).

The upper end of the lifting shaft 41 is rotatably attached to the other end side 43b of an arm member 43 to which one end side 43a is fixed, and the center portion 43c of the arm member 43 is in contact with the outer peripheral portion of the cam member 45. .

As shown in FIG. 4, the outer circumferential shape of the cam member 45 is such that approximately half the circumference A is formed in an arc shape, and the remaining half circumference B has a continuous small waveform along an arc with a smaller diameter than A. It is formed.

Therefore, when the cam member 45 is rotated by the drive of the motor 50 and the portion A comes into contact with the arm member 43, the other end side 43b of the arm member 43
is pulled upward greatly, the elevating shaft 41 rises, and both the two vibrating gates 30 and 35 open.

Further, when the portion B is in contact with the arm member 43, the two vibration gates 30 and 35 vibrate little by little in a closed state.

A pair of vibrating gates 30 formed in this way,
A pair of discharge gates 51 and 52 are provided below 35 for collecting and discharging the rod-shaped articles from the two drop passages L and R all at once.

The discharge gates 51, 52 have free ends 51a,
52a are brought into contact with each other so as to intersect with each other, and the lower surface of the housing 11 is closed to close the vibration gates 30, 3.

1a and 52a are rotated so as to be separated from each other, and the rod-shaped article is discharged below the housing 11. The opening/closing mechanism of this pair of discharge gates 51, 52 is almost the same as that shown in FIG. 3 above.

<Operation of the above embodiment> (Fig. 5) Next, the operation of the embodiment described above will be explained.

For example, when rod-shaped articles weighed into one package by a weighing device or the like are supplied from the two gutter-shaped runways 60 and 61 shown in FIG. They are housed separately at the entrances of the falling passages L and R, which are closed by 25 (FIG. 5a).

Here, when the air cylinders 23 and 28 are both operated and the shutters 20 and 25 are opened, the rod-shaped article is
Each of them falls downward and is accommodated between the vibrating gates 30 and 35 and the partition plate 12. Vibration gate 3
Since the rods 0 and 35 vibrate while closed, the rod-shaped articles that are not aligned gradually align in their orientation (FIG. 5b).

Here, the vibrating gates 30 and 35 are opened, and the articles that have been separated into the two falling paths L and R are collected on the discharge chutes 51 and 52 (FIG. 5c).

Below the discharge chutes 51 and 52, there is a
As shown in FIG.
The rod-shaped articles from No. 1 and 52 are packed together in an aligned state.

In the above embodiment, a pair of vibrating gates 30 and 35 were provided below the shutter, but another vibrating gate may be provided further below.

<Effects of the Present Invention> As explained above, the rod-shaped article filling device of the present invention separates the supplied rod-shaped articles into two falling paths, aligns them, and then collects them, so that when there is a large amount of rod-shaped articles, can also be adequately addressed. In addition, the rod-shaped articles fed onto the shutter are
Since it is made to fall in at least two large steps internally, a more effective alignment effect can be obtained than in the case of vibration alone.

In addition, while the vibrating gate is vibrating, the next rod-shaped article to be supplied can be received by the shutter and kept on standby, so there is no drop in efficiency due to step-by-step discharge, and the aligned rod-shaped articles can be efficiently handled. It can be easily filled in containers etc. all at once.
