Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The disclosed technology is applicable to the field of structural technology of an apparatus that weighs a long object such as dried noodles according to a set weight and sends it to the next packaging process.

<Summary of the gist> Therefore, the invention of this application has a chute provided at the tip of a large-volume, large-volume supply trough provided at the upper part, and a chute provided at the tip of the large-volume large-volume supply trough provided at the top, which is connected to a weighing hopper located below from the opening/closing lid of the pool hopper, The weighing hopper is supported by a weight detection device such as a load cell, and is faced at the tip of a small quantity supply trough.
In order to align the posture of the long objects falling from the large supply trough, the inside of the pool hopper is equipped with a plurality of opening/closing lids arranged at equal heights with respect to the weighing hopper above and below. This invention relates to a long object weighing device in which an opening/closing drive device linked to one or all of the opening/closing lids is provided with a mechanism for applying slight vibrations to the opening/closing lid.

<Prior art> As is well known, with the diversification of life, there is an increase in the distribution market.
There are a wide variety of products handled in supermarkets, etc., and therefore, when handling each package of products in supermarkets, it is common to use packages with set weights, and therefore, set weight measuring devices for various products are It has been developed and adopted in various ways.

Among these, products that are relatively easy to handle, such as lump products such as green peppers and granular products such as peanuts, are relatively easy to handle because they slide down relatively smoothly on the product flow surface of the measuring device.
Superior metering devices have been developed.

By the way, when it comes to weighing long items such as dried noodles, automatic weighing devices have not been developed for a long time because the mechanical part that bends when the product flows through the measuring device changes its posture. However, as shown in many of the inventions in the applicant's earlier applications, various devices such as the angle of inclination of the sliding surface of the product and the mechanism for imparting micro-vibration have been devised and put into practical use, and weighing devices have been developed. There is no risk of damage to products that fall from the internal weighing process to the next packaging process, etc., and for this reason, they have come to be used in supermarket pack centers and the like.

As for these long object weighing devices, it is desired to speed up weight measurement in the same manner as for the above-mentioned lump products and granular products. A large volume close to the negative value is sent to the weighing mechanism, and when weighing,
An ingenious mechanism was devised to supply a small amount of product close to the set target value, with a large volume supply trough installed at the top and a chute at the tip of the trough, which was then fed through a pool hopper to the bottom supported by a weight sensing device such as a load cell. Mechanisms have been developed in which a small quantity supply trough faces the weighing hopper so that the weight detected by the load cell approaches the set target value.

<Problem to be solved by the invention> Therefore, in the seed long object h] measuring device, the long objects such as dried noodles discharged from the upper mass supply trough are sent to the weighing hopper via the pool hopper. In order to be fed, a large amount of long material is roughly weighed in advance in the bulk feeding trough, and the lid is raised and lowered from the underside of the trough surface of the bulk feeding trough into the feeding trough through a slit, so that the bulk feeding is carried out. The height of the pool hopper, which faces the chute at the tip of the trough, cannot be made shorter than the weighing hopper connected to the lower stage, and the small quantity supply trough interferes with the lifting and lowering of the lifter and the weighing hopper. I needed enough height to avoid it.

Therefore, in the process where long items such as dried noodles are fed into the pool hopper from the tip chute of the mass supply trough,
Because the opening/closing lid at the bottom of the pool hopper faces close to the weighing hopper below it, the height from the tip of the chute of the mass supply trough to the opening/closing lid is considerably high, and the pool hopper itself is a long piece that may fall. Objects do not necessarily fall in a horizontal position and fall in an orderly manner; depending on various conditions, objects may fall in an inclined position, or in extreme cases, they may fall vertically and fill the pool hopper. Therefore, long items that are once stored in random positions on the lid in the pool hopper and then discharged into the lower weighing hopper due to the opening of the lid take on complicated and irregular positions, and Naturally, the posture on the flow surface will also be random, and even if an alignment effect is applied by a microvibration device etc. midway, a sufficient effect will not be achieved, resulting in the risk of breakage of long objects during the weighing process. etc., which not only has the disadvantage of lowering the commercial value of the packaged product, but also
There were also problems such as the broken pieces clogging the mechanical parts.

Therefore, constant maintenance, inspection and maintenance of each mechanical part cannot be neglected, which is a disadvantage in that it leads to high costs.

The purpose of the invention of this application is to solve the technical problem of the product misalignment of the intermediate pool hopper that slides long products such as dried noodles from the large quantity supply trough to the weighing hopper based on the above-mentioned prior art, and While taking advantage of the excellent advantages of high-speed weighing processing to accurately set target values through large-volume and small-volume feeding), it also aligns the product posture in the pool hopper and maintains alignment even when discharging and loading into the weighing hopper. It is an object of the present invention to provide an excellent long object weighing device which is capable of maintaining a uniform posture of a long object and which is useful for the field of weighing technology in the distribution industry.

<Means/effects for solving the problem> In order to solve the above-mentioned problem, the structure of the invention of this application, which is based on the scope of the above-mentioned patent claims, is to solve the above-mentioned problem. A long object is fed from the supply section at the base, and the long object is lifted up and down from the bottom of the trough surface at the tip, and the long object weighed to an amount close to the set target value from the negative side is passed through the tip chute by the lid. It is put into the pool hopper,
In this case, in the pool hopper, cushions are placed in stages on the opening/closing lids of the casters, which are arranged at equal heights from the opening/closing lid of the weighing hopper connected to the lower level to the chute. Therefore, due to the opening and closing lids in the pool hopper that open and close intermittently with a phase difference, the sliding height of long objects at each timing is shortened, thereby reducing the sliding height of long objects deposited on each opening and closing lid. The posture is arranged horizontally,
There is no randomness, and therefore, the long objects discharged into the weighing hopper are also placed horizontally in an orderly manner, and furthermore,
At least one of the opening/closing lids is subjected to minute vibrations when opened by a micro-folded cam surface of a cam mechanism connected to the opening/closing mechanism, and as a result, a long object is ejected and fallen from the opening/closing lid that is opened and closed. We have developed a technical means to further align the products so that they are not tilted or vertically placed, but instead are placed in the weighing hopper in an orderly, parallel, horizontal position, and then transferred to the next stage of the process. This is what I learned.

<Embodiments - Configuration> Next, embodiments of the invention of this application will be described below based on the drawings.

In the embodiments shown in Figs. 1 to 5, 1 shown in Fig. 2.3 is a weighing and packaging plant, which is installed, for example, in a pack center of a supermarket, and is used to measure a set weight value of dry noodles as a long product, and to parallelize the long products. The device is designed to be packaged in a posture and fed to the next boxing process, etc., and a long object measuring device 2, which constitutes the gist of the invention of this application, is provided from the base side of the long object, and a long object measuring device 2 is provided in the middle of the L-shape. A well-known packaging device 4 is provided at the end of the rising conveyor 3, and is connected to a next-stage boxing device for cardboard boxes, etc., via a conveyor "V5".

A pool hopper 9 is connected via a trough portion 8 to a weighing hopper 10 connected to the conveyor 3 at its lower part.

As shown in FIG. 1, the main part of the long object weighing device 2 is that the trough section 8 has a trough section 8 on its upper part that is horizontally or gently sloped to measure an amount that is approximately close to the set target value from the negative side. A large quantity supply trough 11 for metering is provided, and a chute 12 having a substantially right triangular cross section facing the pool hopper 9 is provided at the tip of the trough 11, and above the chute 12, a chute 12 is connected to an equipment frame (not shown) via a support shaft 13. An arm 14 that swings by a swing link mechanism (not shown) is provided, and a shutter 16 that comes into contact with and separates from the chute 12 via an adjustment screw 15 at its tip is provided. It is possible to freely adjust the amount of proximity of the large amount of long dried noodles 17 to the set target value from the negative side.

A slit 18 having a width shorter than the width of the long object is formed in the trough surface 11' of the mass supply trough 11 in front of the chute 12, so that the long object 17 to be transferred is placed in a bridge state. to prevent it from falling downward,
On the lower side thereof, the upper surface is inclined, the back wall is formed to be tall, the front side slides on the rear wall surface of the chute 12, and the lid 19 is connected to a link mechanism (not shown) and connected to an arm 20 that swings up and down. A set amount of elongated object 17 is placed on the upper surface of the slit 18 from below and between the back surface of the chute 12 and the rear surface of the chute 12, and the object 17 is lifted up. The long object 17 is transferred to the slope of the chute 12 in a posture flush with the slope of the chute 12, temporarily stored between it and the shutter 16 in the closed state, and discharged into the pool hopper 9. te1
This structure is the same as that disclosed in Japanese Unexamined Patent Publication No. 105021/1983, which is the earlier invention of the above applicant.

Further, a weighing hopper 10 having an opening/closing lid 21 connected to an opening/closing mechanism (not shown) at the bottom thereof is connected to the lower part of the pool hopper 9 so as to face the discharge port of the pool hopper 9.
A small amount supply trough 23 is supported by a weight detection device 22 such as a load cell, and is installed at the bottom of the large amount supply trough 11 and branched and connected to the supply section 7 at a gentle slope at a set angle. The tip of the weighing hopper 1
0, and this structure is also the same as that of the above-mentioned Japanese Patent Application Laid-open No. 58
-105021@ as shown in the publication.

Therefore, in the pool hopper 9, the chute 12
The opening/closing drive device 25 is provided with opening/closing M24.24' in two stages, upper and lower, so as to be openable and closable, at a position that approximately divides the height between the tip of the hopper and the opening/closing lid 21 of the weighing hopper 10 into three equal parts.
．． It is connected to 25' and can be opened and closed by a pin pivot.

The lower ends of the opening/closing lid 24, 24' of the pool hopper 9 and the opening/closing lid 21 of the weighing hopper 10 are, as shown in FIG. The movable panels 27 of the opening/closing lid main body are intertwined with each other in a zigzag shape at their lower edges to form an overlapping shape to hold the long object 17 so as not to damage the long object 17.

The opening/closing drive device @25 is, as shown in FIG.
An inverted triangular link 29 is swingably supported on the frame via a pin 30, and a return spring 34 is inserted between the pin 31 on the base end side and the pin 33 of a bracket 32 provided on the frame. On the other hand, the upper end of the link 36 is pivotally supported by the pin 35 at the tip, and the lower end is connected to the upper opening/closing lid 24 of the pool hopper 9 via the pivotal support of the pin 37. The opening/closing lid 24 can be opened and closed via a pin 39 provided on the frame of the pool hopper 9.

A cam follower 40 pivotally supported between pins 30 and 31 of the link 29 is in contact with a cam 42 connected to a motor 41 that is intermittently operated via a control device (not shown). 29, that is, a cam surface 43 for opening and closing the opening/closing lid 24 is formed.

This opening/closing drive device 25 is attached and connected to the lower opening/closing [24' of the pool hopper 9 and the opening/closing lid 21 of the weighing hopper 10 with substantially the same structure. The opening/closing operation is determined so that the rotation is performed with a predetermined phase difference by operating the motor 41 at a set timing via a control device (not shown).

<Embodiment - Effect> In the above-described configuration, as described above for the supply section 7 of the long object needle N device 2, the long objects of dried noodles are placed horizontally in a parallel posture as much as possible by the packet conveyor (not shown). When they are aligned and supplied, a large amount of long objects are delivered to the large volume supply trough 11 at a flow rate of a set ratio by a divider portion (not shown), and
It is distributed and transferred to the small quantity supply trough 23 at a small flow rate, and is passed by a vibration device (not shown). The lifter 19 is held in a horizontal position in parallel to the upper part as much as possible, but when the ring 20 is turned to the right in the figure by a drive device (not shown) at a set timing, the lifter 19 changes from the solid line state in FIG. 1 to the one-dot chain line state. The slit 18 rises from the bottom of the trough surface 11'.
The upper inclined surface penetrates through the chute 12 and rises with a long object of set capacity placed between the upper inclined surface, the back surface of the back and the back surface of the chute 12, and the upper inclined surface passes through the inclined surface of the chute 12. The link 20 stops when it reaches a position where it is flush with the surface,
The long object 17 placed thereon is held and stored in a portion between the slope of the chute 12 and the shutter 16 of the arm 14.

As described above, by adjusting the shutter 16 forward and backward with respect to the arm 14 using the adjustment screw 15, the amount of the elongated object 17 stored between the chute 12 and the shutter 16 can be adjusted.

Then, at a set timing, a control device (not shown) causes the arm 14 to move the pin 13 against the frame via a drive mechanism.
Then, the long object 17 which is clamped and held at T (+N) is dropped into the pool hopper 9 and released.

Therefore, each opening and closing provided in two levels, upper and lower, inside the pool hopper 9! 24.24' is the opening drive device 2 shown in FIG.
5, the motor 41 is controlled at a set time difference through the control TLL device.
As a result, the lower opening/closing lid 24' is opened by the link 29.36 via the cam 42 and the cam follower 40, and the upper opening/closing lid 24 is closed when the long object 17 is discharged into the weighing hopper 10. The long object 17 is discharged from the chute 12 and falls by opening and closing the upper stage! 24 is discharged and deposited.

And each opening/closing M24.24' opens/closes the chute 12 and weighing hopper 10! Since it is installed at a height that roughly divides the height of 21 into thirds, the distance it falls is not large, so the posture of the long object during the falling process will not be diagonal or vertical. First, the elongated object 17, which is held between the chute 12 and the shutter 16, falls in a horizontally aligned state in which it is almost maintained in a parallel position. Therefore, the long object 17 placed and stored on the opening/closing lid 24 is placed in a horizontally parallel position. It will be placed.

When the upper opening/closing lid 24 is open, the lower opening/closing lid 24' is closed, and therefore the upper opening/closing 124 is closed.
Furthermore, since the height distance between the lower opening and closing lids 24' is not so large, the long object 17 that falls further maintains the state of horizontally parallel posture placed on the upper opening and closing lid 24. Then, when the lower opening/closing lid 24' is opened via the control device at the set timing, they are discharged and dropped into the weighing hopper 10 with the opening/closing M21 closed while maintaining the same horizontal alignment state. be done.

Therefore, the long objects 17 in each process that intermittently fall onto the opening/closing lid 24, 24' and the opening/closing i21 of the weighing hopper 10 fall while maintaining the horizontally aligned state, and are placed diagonally. Therefore, no breakage or the like occurs during the falling process.

Moreover, since the falling process at each stage is short, the impact force caused by falling is softened, and breakage etc. due to this will not occur.

Further, as shown in FIG. 4, the zigzag portions 28 at the lower edges of each opening/closing lid overlap each other, so that long objects will not get caught and break.

Of course, the lifter 19, arm 14, opening/closing lid 24.24
', 21 are opened and closed under optimal control according to a program of a control device (not shown).

Then, the weight on the mass supply trough 11 side fed into the weighing hopper 10 is detected by the weight detection device 22, and the detected weight is input into the microcomputer and compared with the set target value, resulting in a plus minimum over ffi. A vibrating device (not shown) of the small quantity feed trough 23 is driven to feed the small amount into the weighing hopper 10, and when the set weight is reached, the imaging device stops and the long pieces from the small quantity feed trough 23 are fed into the measuring hopper 10 little by little. The product supply is stopped, the opening/closing lid 21 is opened by the opening/closing drive device 25, and the material is supplied to the packaging device 4 via the L-shaped conveyor 3 via a timing hopper (not shown) in the next stage, and the bags made of polyethylene film are packaged. etc., and is transported by the conveyor 5 to the next step of packing into cardboard boxes, etc.

Therefore, in the above-mentioned process, the impact during the sliding process of the elongated object 17 from the bulk supply trough 11 to the weighing hopper 10 in the interposed pool hopper 9 is softened, and the impact in the falling posture is softened. When placed horizontally and in parallel, they remain aligned, and problems such as breakage do not occur.

Therefore, there is no need for maintenance, inspection, and maintenance monitoring by workers.

Accordingly, the invention of this application provides an opening mechanism for one of the multiple opening/closing lids 24, 24' in the pool hopper 9, for example, the lower opening/closing lid 24' for the weighing hopper 10 in this embodiment. By applying a slight vibration just before the weighing hopper 1, the long objects 17 that are unexpectedly tilted or placed in a nearly vertical state are forcibly aligned.
Although the posture of ejecting and falling toward 0 is made to be more aggressively arranged horizontally, as in the embodiment shown in Fig. 6,
By forming a slightly folded cam surface 43' at the front in the rotational direction of the cam surface 43 of the cam 42' that the cam follower 40 of the link 29 comes into contact with, when the cam 42' rotates to the left in the figure as shown by the arrow, Since the slightly folded cam surface 43' comes into contact with the cam follower 40 before the cam surface 43, the cam follower 40 vibrates slightly before performing a cam operation against the cam surface 43, and as a result, the opening/closing lid 24 is moved through the link 36. ′
The camera performs minute imaging, and therefore gives minute vibrations to the long object placed just before opening, and photographs the long object that is in a tilted state or nearly vertical state that is accidentally mixed in. In order for the cam surface 43 to operate the cam follower 40,
The opening/closing lid 24' is opened to allow the objects to be dropped into the weighing hopper 10, so that the long objects 17 thrown into the weighing hopper 10 are always maintained in a horizontally parallel position each time they are weighed. The state of transfer to the next stage also maintains the parallel alignment and horizontal state.

Incidentally, as in the embodiment shown in FIG.
24' is opened, and therefore, even in the process of falling, the long object 17 sliding on the opening/closing lid 24' is given a slight vibration, and furthermore, the long object 17 input into the weighing hopper 10 is It is possible to maintain the horizontal parallel posture state.

It is needless to say that the embodiment of the invention of this application is not limited to the above-mentioned embodiment. For example, in the above-mentioned embodiment, the cam 42'
Although a slightly folded cam surface is provided to give a slight vibration to the cam 42, various embodiments such as giving a slight (twisting) motion to the drive shaft of the cam 42 can be adopted.

Further, the multi-stage opening/closing lid in the pool hopper 9 is not limited to two stages, but design changes such as three or four stages are also possible.

Of course, the target long object is not limited to dried noodles, but also incense sticks and the like.

<Effects of the Invention> As described above, according to the invention of this application, basically, in measuring devices for long items such as dried noodles that have been put into practical use so far,
The interposed pool hopper, which receives and transfers long items from the upper-stage large-volume supply trough to the lower-stage weighing hopper to speed up weighing processing, has a considerable height due to the lifter interposed between it and the lower-stage small-volume supply trough. Despite being forced to
The multi-stage opening/closing lid installed inside the product has a multi-stage cushioning effect, which absorbs the impact during the discharge and fall process and prevents damage to the product. Also, because the falling process is shortened in multiple stages, the product becomes inclined or vertical.
In addition, since the risk of contamination is prevented, not only is the excellent effect of preventing the breakage of products that have slipped in the complicated flow path and not degrading the product yield, but also
This has an excellent effect in that debris such as broken parts does not get mixed into each mechanical part and become jammed, causing functional problems. This has the advantage of eliminating the need for inspection, maintenance, monitoring, etc., and has the excellent effect of reducing running costs.

Further, since it is sufficient to simply provide multiple stages of opening/closing lids in the pool hopper, there is also the advantage that the equipment does not become particularly large-scale and the occupied space of the plant does not need to be expanded.

At least one of the multi-stage opening/closing lids provided in the pool hopper is equipped with a micro-vibration mechanism for the opening/closing device, so that the opening/closing lid for the weighing hopper is activated immediately before or at the time of opening. Since the opening/closing lid can be given micro-vibration, it is possible to forcibly apply micro-vibration to the long object during the process of dropping it into the weighing hopper. Even if a long object gets mixed in, it is possible to maintain a horizontally parallel alignment state just before it falls into the weighing hopper, preventing the above-mentioned breakage of long objects in the separate hopper as well as in subsequent processes. It has the excellent effect of preventing clogging of the mechanical parts.

Furthermore, since the long object does not break during the transfer process, there is also the effect that the packaging operation in the next stage of packaging process is not hindered.
