Description

[Detailed description of the invention] <Industrial application field> The disclosed technology is a dispersion table that uniformly distributes products in the circumferential direction at the upper part of a combination weighing device in which a set number of weighing mechanisms are disposed in the circumferential direction. It belongs to the field of structural technology in which lubricants such as alcohol are applied to the product so that it can be dissipated smoothly.

<Summary of the gist> This invention is based on a combination weighing device for sticky products such as cheese and kamaboko (kamaboko fish paste), which has a set number of heads arranged on the radial trough on the circumference of the device, and then weighs the product in an approximately average amount. A dispersion table of a dispersion supply device that supplies alcohol in batches is installed below an upper loading device such as a bucket conveyor, and alcohol or
This invention relates to a dispersion supply device for a combination metering device in which a nozzle for applying a lubricant such as a mixture of alcohol and air is faced, and in particular, a dispersion table that is flared downward and a dispersion table that is flared downward is placed on top of the dispersion table that is flared downward. A tapered cone type guide table is provided with a set gap from the dispersion table, and a nozzle is provided inside the guide table facing upward, and lubricant is applied in small amounts onto the dispersion table through multiple nozzle bodies. This invention relates to a distributed feeding device for a combination metering device that enables uniform coating.

<Prior art> As is well known, in the distribution market, various products are processed in large quantities. For example, in supermarkets, etc., a process is adopted in which a single product is filled into a package, bag, etc. at a set weight. However, in this case, it is necessary to avoid measuring an amount that is too small compared to the set weight, and therefore, the amount that exceeds the set weight is measured by a so-called combination using a microcomputer. BACKGROUND OF THE INVENTION Automatic combination weighing devices based on weighing methods are becoming widely used.

In addition, many other product handling devices such as packaging machines and automatic filling machines are used.

In order to install these devices in a limited space and perform specific tasks, the devices are generally compact, and some devices are moved laterally for each process via a conveyor or other transport device. However, there are many processes that follow the product conveyance process using a drop from the upper inlet supply section to the lower discharge section.

Therefore, in general, when moving products using head, the distance between each stage is shortened in order to both make the equipment more compact and to speed up product processing. It often takes the form of a slide and fall.

In this case, for the complicated and curved product sliding surface,
It is necessary to reduce the friction of the sliding surface so that the products can slide down quickly and uniformly. For example, prunes,
Products with flexible bodies or wet surfaces, such as jelly, cheese, and kamaboko fish cakes, have a slow sliding speed, leading to congestion in the supply to the next stage, which may impede the smooth operation of the device.

To deal with this, for example, an air nozzle is placed facing the sliding surface of the product and compressed air is forcibly injected at a predetermined timing, as shown in Japanese Utility Model Application Publication No. 58-32333, which was an earlier invention of the applicant. There are some methods that force the product to slide down to increase the sliding speed and speed up the process, but this has the disadvantage of increasing power costs due to the high pressure of compressed air. There is also the problem that product damage may occur due to the collision of the following product with the stagnation of the preceding product.Also, in the case of prunes, jelly, etc., the problem is that it is impossible to wipe off the residue of adhering substances that accidentally adhere to the sliding surface. It was hot too.

On the other hand, a device was devised to spray lubricant onto the sliding surface of the product as shown in Fig. 4 of Utility Application No. 1988-88074, which was also an earlier device of the applicant. I had a problem like this.

<Problems to be solved by the invention> That is, stands 3, 3, etc. are erected at predetermined positions on the frame 2 of the combination weighing device 1, spray nozzles 4, 4 are attached to the tips of the stands, and the radiation trough 5 and pool hopper 6 are installed. , the weighing hopper 7, the collection chute 8, etc., are sprayed with lubricant to coat them on the product sliding surfaces, so that the products slide down smoothly.

At the same time, in the process of supplying and distributing products from a bucket conveyor (not shown) on the top stage to the dispersion table 10 via the guide 9, the spray nozzle 4 is placed above this dispersion supply device to form an overhanging shape. Since the lubricant is supplied together with the product, it is difficult to apply the lubricant evenly over the entire surface of the distribution table 10, and as a result, the lubrication process across the radiation trough 5 and pool hopper 6 is uneven. This method has the disadvantage that it is easy to cause damage, and it also has the disadvantage that it requires a large amount of lubricant such as alcohol, resulting in high costs.

The purpose of this invention is to solve the technical problem of uniformly applying lubricant to the distribution table at the upper product loading section of the combination weighing device based on the above-mentioned conventional technology. By making it possible to use lubricants, ensuring smooth sliding of products from the initial loading process to the final process, and significantly reducing the cost required for lubricant application, product handling in the distribution industry is improved. It is an object of the present invention to provide an excellent distributed supply device for a combination metering device that is useful in the field of technical application.

<Means/effects for solving the problems> In accordance with the above-mentioned purpose, the structure of this invention, which is summarized in the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problems. In the process where the product is loaded and transferred to the next packaging process through the weighing section of each head, if the product is highly sticky such as cheese or kamaboko, a lubricant such as alcohol is applied to the sliding surface. In doing so, the lubricant is jetted upward from the inner center of the guide table, which is also formed in a downwardly expanding shape above the dispersion table of the dispersion supply device and has a tapered cone shape that expands downwardly. Furthermore, by uniformly applying lubricant in the circumferential direction to the dispersion table below the nozzle body using a set number of nozzles, the product slides down the dispersion table uniformly and smoothly, and in addition, a small amount By applying the lubricant in a flowing manner on an average basis, the amount of lubricant is kept as low as possible, allowing the product to smoothly slide down from each head, and only a small amount of lubricant is consumed, reducing the amount of lubricant needed. Depending on the situation, at the pool hopper, weighing hopper, and gathering hopper,
Furthermore, the technical means of spraying lubricant ensures smooth sliding from the initial process to the final process of combination weighing, which reduces the amount of lubricant used and reduces costs. This study included the following.

<Embodiment - Configuration> Next, an embodiment of this invention will be described below based on FIGS. 1 to 3. Incidentally, the same parts as those in FIG. 4 will be explained using the same reference numerals.

In the embodiment shown in FIGS. 1 and 2, an electromagnetic three-dimensional vibration device 12 is provided on the underside of a support plate 11 provided on the device frame 2 and provided at the center inside the device, similar to the conventional embodiment shown in FIG. In addition, a stem 13 is concentrically erected on the upper side, and a disc-shaped retainer 14 at the upper end is provided with a tapered cone type dispersion table 10 that widens downward as in the conventional system. Furthermore, a sub-stem 15 integrally provided above the stem 13 is provided with a guide table 16 which also has a downwardly expanding shape and has a steeper inclination angle than the inclination angle of the dispersion table 10. It has a ring-shaped setting gap 17 with respect to the table 10, and
Guide table 6 is attached to the shank of substem 15.

As shown in FIG. 2, the lubricant supply passage 20 is connected to a mixer 21 for alcohol and air as a lubricant, and is further supplied with alcohol via a nipple 22, an alcohol passage 23, and a header 24. It is connected to an alcohol tank 26 by a passage 25.

From the header 24, alcohol passages 23 (only one is shown in this embodiment) are provided at predetermined locations via the nipples 22, for example, to the pool hopper 6, the weighing hopper 7, the collecting hopper 8, etc. Nozzle 4 against the sliding surface
The mixer 21 is connected to the mixer 21 of FIG.

The other nipples 27, 27, . . . of the mixers 21, 21, .

The solenoid valve 33 provided in the alcohol passage 25 and the solenoid valves 33, 33, .
33... by controlling the opening and closing of each mixer 21, 21...,
That is, the ejection of a lubricant mixture of alcohol and air from the nozzles 4, 4', . . . is controlled.

<Embodiment - Effects> In the above-described configuration, when the combination weighing device is put into operation, highly viscous products such as cheese and kamaboko are delivered to the center of the device through the guide 9 by a bucket conveyor (not shown) from the upper input port. When the products are introduced from above, the products are uniformly distributed in the circumferential direction from the guide table 16 which vibrates three-dimensionally together with the dispersion table 10 by the integrated electromagnetic vibration device 12.The products are then dispersed by the dispersion table 10 in a conventional manner. Similarly, the pool hopper 6 passes through each radiation trough 5.
Then, they are weighed in a predetermined manner by the weighing hoppers 7, 7, . . . , a combination is selected, and then transferred to the next packaging process via the collection hopper 8.

This combined weighing process is similar to the conventional method.

In this invention, the alcohol and air from the alcohol tank 26 and the high-pressure air source 31 are mixed with gas and liquid in the mixer 21, 21, etc. through the opening and closing of the electromagnetic valves 33, 33, . . . by the control device 35. and is fed to each nozzle 4, 4'...
In the dispersion supply device located at the upper center of the device, the nozzle 4' sprays the jet from below to the upper side of the guide table 16, and then the inside of the guide table 16 is sprayed from the nozzle bodies 18, 18, . The side surface is sprayed, and the circumferential tip of the guide table 16 is sprayed onto the dispersion table 10.
By forming a ring-shaped gap 17 of a set size, as shown by the white arrow in Fig. 1,
It is uniformly ejected and dispersed in the circumferential direction of the dispersion table 10 along with the highly sticky cheese and kamaboko that are thrown in from above on the dispersion table 10 .

In this case, the electromagnetic vibration device 12 disperses the product uniformly in the circumferential direction, and the guide table 16 and
Since the substem 15 also vibrates, the nozzle body 1
The gas-liquid mixed alcohol and air lubricant from 8 is uniformly sprayed onto the dispersion table 10.

Therefore, at the base of the distribution table 10, the lubricant is sprayed uniformly in the circumferential direction, without being sprayed unevenly, and therefore, the minimum amount of lubricant is applied in as small an amount as possible. This will continue to be the case.

In this case, each electromagnetic valve 33 controlled by the control device 35 may be in a normally open state or may be in an intermittent open/close state.

In this way, the lubricant is uniformly applied over the entire area of the distribution table 10, so that the product slides down the distribution table 10 smoothly over the entire surface, and the lubricant is applied smoothly to each radiation trough 5. will be supplied to.

Incidentally, the lubricant alcohol naturally evaporates from the dispersion table 10 to the radiation trough 5 or to the pool hopper 6 beyond that, and does not have any adverse effect on the food product.

On the other hand, in the pool hopper 6, the weighing hopper 7, and furthermore the collection hopper 8, the spray nozzles 4 facing each sliding surface spray the lubricant as uniformly as possible to the sliding surface as in the conventional method. , to ensure that the product slides down smoothly on the sliding surface.

In this way, the necessary minimum amount of alcohol is sprayed from the base of the upper input side of the combination weighing device 1 to the collection hopper 8, thereby ensuring uniform sliding of the products.

In the embodiment shown in FIG.
4 is provided, and sub-nozzle bodies 18, 18', . In the embodiment as well, the spray application state of the lubricant such as alcohol to the distribution table 10 is maintained;
The operation and effect are the same as those of the above-mentioned embodiments, and there is no difference therein.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, various embodiments may be employed, such as providing a reversing plate or the like at the tip of the nozzle that is provided upward inside the guide table. can be adopted.

Furthermore, it is also possible to adopt a mode in which only alcohol is applied in small amounts along a dispersion table without mixing bubbles.

Furthermore, in terms of design changes, there are various lubricants that can be used in addition to alcohol, and any lubricant that does not adversely affect the processed products can be used.

Of course, the target products can also be applied to products other than cheese, kamaboko, etc.

<Effects of the invention> As described above, according to this invention, basically, in combination weighing using a combination weighing device having a set number of heads in the circumferential direction of highly viscous products such as cheese and kamaboko, Because the dispersion supply device applies lubricant such as alcohol to the dispersion table uniformly in the circumferential direction, it is possible to guarantee that the product will smoothly slide down on the dispersion table at the base end of the dispersion. The effect is produced.

This has the excellent effect of ensuring uniform dispersion of the product to each head of the weighing hopper as well as to each pool hopper via the radiation trough.

Moreover, since the lubricant can be uniformly supplied to the distribution table in the circumferential direction, the amount of lubricant used can be kept to the minimum necessary, and running costs can be reduced, which is an excellent effect.

Since the upper guide table at the base end of the dispersion table is formed into a downwardly tapered cone shape that widens toward the end, the lubricant jetted from below against the guide table has a kind of reflection effect on the dispersion table. Therefore, the excellent effect of uniformly dispersing the lubricant from the circumferential gap between the guide table and the dispersion table is achieved.

The lubricant inside the stem can also be connected to a rotating device via a suitable swivel joint or the like so that it can be sprayed while rotating.
