[0001] Straw Transffer Device [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a device for automatically conveying a straw to a collecting hopper for packaging straw from a corrugating device of a straw (a so-called straw), and more particularly to a device capable of controlling the conveying speed of a straw, This makes it possible to maintain the cleanliness of the product by preventing the hands of the workers from touching the product unnecessarily due to the smooth product transfer between the processes and the smooth product transfer and by the efficient arrangement of the workers between the respective processes To a straw conveyance device for improving productivity by reduction.

Generally, in a manufacturing process of a straw, wrinkles are firstly formed in a first facility which forms a wrinkle on a part of the straw, and then the second facility is collected in a collecting hopper for packaging, and then the straw discharged from the collecting hopper Packaged. In such a straw manufacturing process, when the straw discharged from the first facility for the wrinkle forming process is manually collected in the collecting hopper, which is a secondary facility for the packaging process, a manual feeding method is used. In this case, There is a problem that the production cost is increased and a physical impact may be applied to the straw while being handled by a hand, thereby causing a possibility of quality deterioration. Therefore, there has been a need to automate the process of transferring the straw from the creasing process to the packaging process.

In order to meet such a demand, for example, Japanese Patent Registration No. 10-0407423 (registered on Nov. 17, 2003) "straw packing machine" discloses an apparatus for automatically conveying straw using a conveyor belt, 1 schematically illustrates the overall configuration thereof. The straw packaging machine 10 is discharged by the molding part conveyor 12 after the straw S supplied from the straw supply hopper 11 is corrugated. The molded part conveyor 12 is driven by a drive motor 13. The straw discharged from the molding part conveyor 12 is transferred by the conveying conveyor 14 to enter the straw collecting hopper 15 and collected. The straw collected in the straw collecting hopper 15 is supplied to a packing machine (not shown) and packed. The conveying conveyor 14 has a horizontal portion 141 for horizontally conveying the straw between the forming portion conveyor 12 and the straw collecting hopper 15 and a rear portion of the horizontal portion 141 on the side of the collecting hopper 15 And an inclined portion 142 connected thereto. The conveying conveyor 14 is driven by a drive motor 13 that drives the forming part conveyor 12. The straw discharged from the molded part conveyor 12 moves horizontally by a predetermined distance by the horizontal portion 141 as it is discharged and then descends along the inclined portion 142 to enter the collecting hopper 15 So that it could be automatically collected into the collection hopper 15.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The straw transfer device provided in accordance with an aspect of the present invention is a part of a straw manufacturing apparatus that forms a wrinkle on a straw and discharges the product as a packaged product. As described above with reference to the example illustrated in Fig. 1, the straw manufacturing apparatus can be continuously discharged at a constant speed by the forming part conveyor 12, with the corrugated straws formed by the corrugating machine. The forming part conveyor 12 is operated by the drive motor 13 and causes the straw to be continuously discharged at a constant speed. These straws are collected in a collecting hopper 15 and then wrapped by a wrapping machine.

Conventionally, a means for driving the conveying conveyor 14 for conveying the corrugated straw S discharged from the forming part conveyor 12 to the collecting hopper 15 is provided to the driving motor 13 of the forming part conveyor 12 ). With this structure, the speed of the forming part conveyor 12 and the speed of the conveying conveyor 14 can be made equal. Therefore, it was expected that the wrinkled straw would be continuously conveyed from the molded part conveyor 12 through the conveying conveyor 14 to the collecting hopper 15 at a constant speed.

However, there are many cases where troubles occur when straws, which are continuously conveyed at a constant speed by the shaping conveyor 12 and the conveying conveyor 14, are collected in the collecting hopper 15, so that the operator must continually monitor the process There is a problem that there is a need to intervene immediately when a trouble occurs and there is a possibility that an increase in production cost and a deterioration in quality may occur.

Therefore, in order to solve this problem, in the present invention, by providing a buffer space that can be temporarily stored before the straws S conveyed on the conveying conveyor 14 enter the collection hopper 15, The straws entering into the collecting hopper 15 can enter at a constant speed at regular intervals, thereby improving the production efficiency.

2, a straw conveying device according to an embodiment of the present invention is provided between a conveying conveyor 14 and a collecting hopper 15, and a straw conveyor 14 (conveying conveying conveyor 14) S to the collecting hopper 15 after collecting the sample S from the collecting hopper 15.

The buffer collecting unit 20 includes a buffer space unit 22 having a substantially rectangular parallelepiped shape and having a hollow shape. The buffer space unit 22 has an inlet 24 formed at one side thereof and an outlet 24 formed at the other side thereof. And a straw guide plate 26 formed at the inlet 24 and guiding the introduction of the straw.

On the other hand, the conveying conveyor 14 includes a horizontal portion 141 starting from the discharge end of the forming portion conveyor 12 and horizontally conveying the straw S in the advancing direction toward the collecting hopper 15, And an inclined portion 142 which is inclined at a predetermined angle from the leading end in the advancing direction of the portion 141 to the downward direction.

The straw S discharged from the discharge end of the forming part conveyor 12 is transferred to the conveying conveyor 14 and is first advanced toward the collecting hopper 15 by the horizontal part 141 of the conveying conveyor 14 . Thereafter, the straw S is conveyed along the inclined portion 142 formed in succession to the horizontal portion 141.

The straw S conveyed by the slope portion 142 is guided to the lower portion of the buffer collecting portion 20 below the slope portion 142, that is, the lower portion of the buffer space portion 22, ) Into the buffer space portion 22.

A straw guide plate 26 is preferably formed outside the inlet 24. The straw guide plate 26 is a guide plate for guiding the straw S conveyed by the inclined portion 142 of the conveying conveyor 14 to the inlet 24 side of the buffer collecting portion 20.

In this way, the straws S entered into the buffer space portion 22 can be lifted up from below by receiving force by the entry speed. The raised straws S can be discharged through the outlet 28 formed on the other side of the buffer space portion 22. [ Straws S discharged from the outlet 28 can be transferred into the collecting hopper 15 through the upper portion of one side of the collecting hopper 15 to which they are connected.

As described above, the collecting hopper 15 for packaging according to the present invention is provided with a buffer collecting part 20 having a separate buffer space. Accordingly, since the straws whose alignment positions are disturbed in the process of being conveyed by the forming part conveyor 12 and the conveying conveyor 14 can be linearly aligned in the buffer collecting part 20, The straw 20 can be automatically and continuously collected in an optimal alignment state, so that the production efficiency can be improved.

According to a preferred embodiment of the present invention, as shown in Fig. 3, the conveying conveyor 14 is provided with a plurality of grooves 143 at regular intervals such that the straw S can be seated at right angles to the conveying direction It is preferable that it is a timing belt.

2, it is preferable that the drive motor 13 for driving the molded part conveyor 12 and the drive motor 30 for driving the conveying conveyor 14 are installed separately from each other. This makes it possible to separately set the conveying speed of the conveying conveyor 14. The operator can freely set the speed of the conveying conveyor 14 and set the most optimal conveying condition according to the nature of the work.

FIG. 4 is a schematic view illustrating a straw transfer device having a buffer collecting portion and a warp conveyor according to another embodiment of the present invention, and FIG. 5 is an enlarged view of portion A of FIG.

The straw conveying apparatuses illustrated in Figs. 4 and 5 are provided so as to be driven separately by respective motors 50a and 50b so as to be able to convey the straw s to be conveyed as a plurality of rows stacked in an inclined section And a buffer collecting unit 70 installed between the horizontal conveyor 14 and the inclined conveyor 40 for discharging the straw s conveyed in a stacked state in a plurality of rows.

The buffer collecting unit 70 collects the straw S conveyed by the horizontal conveyor 114 and discharges the collected straw S toward the inclined conveyor 140 in a stacked manner in a plurality of rows. The buffer collecting unit 70 having such an action is provided with a straw collecting body 74 having an upper, a lower, and one side open in the form of a straw collecting space 72 having a predetermined width. A straw inlet 76 is formed in the front of the straw collecting body 74 to allow the straw s conveyed from the horizontal conveyor 114 to flow. One end of the inclined conveyor 140 extends from the opposite side of the straw inlet 76 to the inside of the straw collecting space 72 and is positioned in a state of facing the one end of the horizontal conveyor 114, s to be discharged. A straw guide plate 75 is provided in the straw collecting body 74 to stably transfer the straw s introduced from the inlet toward the inclined conveyor 140. The straw guide plate 75 is installed in the form of a leg which crosses the opposite end of the inclined conveyor 140 of the horizontal conveyor 114 inside the straw collecting body 74 so as to incline the straw conveyed from the horizontal conveyor 114 So that it can be smoothly conveyed to the conveyor 140 side.

That is, the straw guide plate 75 is composed of a band-shaped plate having a predetermined width and is installed so as to be supported between timing belts (see FIG. 3) constituting the slope conveyor 140 and the horizontal conveyor 114 So that the horizontal conveyor 114 and the inclined conveyor 140 serve as guides for stably conveying the straw without giving any trouble to the front edge.

And a straw guide plate 77 for guiding the straw s to be fed to the inlet 76 is also provided. One end of the straw guide plate 77 is extended to the outside of the inlet 76 in such a manner as to cover the end portion of the horizontal conveyor 114 and the other end extending from the inlet 76 is also connected to the straw collecting body 74 And is formed at a predetermined inclination angle with respect to the upper side. This inclination angle is horizontally arranged so as to cover the upper part of one end of the inclined conveyor 140 so as to form the same inclination angle as that of the inclined conveyor 140 so that the conveyance of the straw s to the inside of the straw collecting body 74 In addition, in the collection state, the sludge (s) is frictionally arranged to be arranged in a laminated state.

An upper guide 60 for connecting the buffer collecting unit 70 and the collecting hopper 15 is installed. The upper guide 60 may be formed in an elongated band, plate, line, or net shape having a predetermined width. One end of the upper guide 60 is connected to the end of the straw guide plate 77 located at the upper portion of the buffer collecting unit 70 and the other side extending from the straw guide plate 77 is located at a position spaced from the inclined conveyor 140 And installed on the upper side of the inclined conveyor 140 so as to face the entrance of the straw collecting hopper 15. This configuration allows the straw S stacked in a plurality of rows discharged from the buffer collecting unit 70 to be elastically pressed and guided so as not to be disturbed into the collection hopper 15. [ That is, the feeding of the slope section allows the straw to be conveyed while rubbing between the inclined conveyor 140 having the timing belt structure as shown in Fig. 3 and the upper elastic guide 60 at the upper part of the straw . For this reason, it is also desirable that the upper guide 60 made of an elongated band, plate, string or net having a predetermined width has an elastic force. The inclined conveyor 140 may be configured at any angle and any angle from the horizontal conveyor 114 to the collecting hopper 15. The inclined conveyor 140 can take a function of feeding a straw in a large amount instead of transporting the straw one by one at regular intervals. It is preferable that the slope conveyor 140 is independently controlled in speed by a separate driving motor 50b. Alternatively, the driving of the warp conveyor 140 may be interlocked with, for example, the forming part conveyor 12 of the primary process and / or the horizontal transfer conveyor 114 of the transfer process.

According to the embodiment shown in Fig. 4, there is provided an advantage that it can be applied to a straw transfer between processes having height differences. This embodiment uses the resistance of the lower conveyor belt and the upper guide to prevent the straws from flowing down when the straw product discharged in the primary process, that is, the wrinkle forming process, is collected in the secondary process, that is, the collection hopper for the packaging process It has structural characteristics.

The straw transfer device according to the above-described various embodiments of the present invention need not be limited to the example shown in the drawings, but may be widely used for various transfer methods of existing inter-process products. It will also be apparent to those skilled in the art that the present straw transfer device is also applicable to straw products that are not corrugated, as well as corrugated straw products.
