The invention relates to a weighing device in which photoelectric sensors for detecting products are provided on both sides.

<Prior art> As is well known, consumer life has become active, and the handling of products in the secondary market such as supermarkets has become wide-ranging, and various latest technologies have been introduced to measure the quantity of products. The flow of goods is smooth and the processing efficiency is improved.

Among them, for the weighing of various products, generally the weight of packages etc. for each set weight is widely adopted, and the set weight of one product is never smaller than the set weight in the packaging process. It should be avoided, and the overweight is not preferable for the supply side either. Therefore, it is necessary to use the high-speed operation of the microcomputer based on the theory of statistics and probability to weigh the set weight with a plus minimum overweight. Quantitative weighing devices such as so-called combination weighing devices have come to be used, and 10, 12, 14 can be used for granular products such as peanuts and chip products.
Efficient measurement processing is performed by using a combination measurement device of a circular arrangement in which a predetermined number of heads are arranged in a circular arrangement and processed at high speed.

Then, the products to be loaded from the upper center of the combination weighing device are evenly distributed on average to each head of the circular array, and a uniform stroke is followed for each head in the sliding process in each pool hopper and weighing hopper. Finally, they are aggregated and discharged from the collecting chute to the next package process, etc. Therefore, the same process in each head contributes to the improvement of weighing.

<Problems to be Solved by the Invention> Thus, in the combination weighing device having a circular array of a predetermined number of heads of the type, for example, in the case of flow-type quantitative weighing by continuously feeding products such as peanuts and potato chips. There is no particular problem, but recently, the predetermined number of the combination of expensive products such as chocolate and cheap products such as candy, and the weight of 1
With the appearance of distribution of products to be packed in a pack, each product can be stored in a pack such as an expensive chocolate twist packaging candies and the like, and a predetermined number of cheap candies can be supplied to replenish the total weight of each product. Above all, it is extremely important to control the supply of a predetermined number of expensive twisting candy packaging such as chocolate, and therefore, the kind of expensive twisting candy packaging in the feeding and conveying process of the product to be supplied to the quantitative weighing device. Individual line-up supply is becoming more important.

However, in the conventional combination weighing device with a predetermined number of heads, parallel feeding of products such as the seed twist packaging candy and the combination weighing are performed as shown in FIGS. 13 to 17. That is, in the combination weighing device 2 which is controlled by the controller 1 through the cable 16 in a predetermined manner, a charge hopper 5 as a product loading portion is provided on an upper portion of a frame 4 having a panel 3, and a conveyor or the like connected from the preceding stage (not shown). The twist packaging candy 20 shown in FIG. 21 that is thrown in by means of the transfer troughs 8 arranged in parallel with a predetermined number of heads mounted and fixed on the electromagnetic vibrator 7 via the chute 6 is forwarded to the pool. It is fed into the hopper 9 and put therein, and then the pool hopper is fed to the weighing hopper 11 supported by the load cell 10 provided in the frame 4 in a predetermined manner. The lid 12 of 9 is opened and closed to measure its weight, and the combined weight calculation operation of the weight equal to a predetermined weight value or the recent weight is performed, and the lid 13 is opened and closed by the link mechanism to be set in the collecting chute 14. It was so arranged that it was thrown in and conveyed from its discharge port 15 to the next packaging process or the like via a conveyor (not shown).

<Problems to be Solved by the Invention> Therefore, in the combination weighing device 2 of the conventional type, the chute 6 is discharged from the lower discharge port of the charge hopper 5 of the product input section.
In the process of individually discharging and feeding small amounts to the respective transport troughs 8 via the feeding troughs 8, the size of the product such as the twist packaging candy 20 is generally different in the sectional size and the longitudinal size. In order to perform smooth discharge to the discharge port, it is necessary for the size to be relatively small. In this case, if the product length size is about the width of the discharge port or more, the charge hopper Each of the products in the attitude state that is randomly supplied within 5 causes so-called jamming and jamming, or the transport trough 8 is advanced in a random attitude and accurate combination weighing cannot be performed, and the packaging process is performed. There was a problem in that there was a disturbance in the combination of the number of expensive twisted packaging candies 20 such as chocolate and other inexpensive products.

Further, in the combination weighing device 2 of this type, each transport trough 8 is placed on a pair of leaf springs 18, 18 on the base 4'provided on the device frame 4, as shown in FIGS. It is mounted and fixed via a bracket 19, and is formed in a rain gutter shape in a length posture along the vibration front-rear direction of the electromagnetic vibrator 7, and the vibrator 7 is vibrated in the front-rear direction by repeating the so-called dance phenomenon and vibration. The product 20 to be supplied was vibrating and transported.

That is, the trough 8 having a predetermined cross section has a bracket on the trough 8.
19 is provided and is mounted on the base 4 ′ fixed to the apparatus frame 4 via the front and rear vibration leaf springs 18 and 18 on the upper part of the electromagnetic vibrator 7 so that the longitudinal directions thereof coincide with the front and rear vibration directions. It is fixedly installed and the 21st from the charge hopper 5
Solid products such as twist packaging candy as shown in the figure 20
Is supplied from the base side and is subjected to vibration in a predetermined front-rear direction by co-operation of the iron core facing the electromagnetic coil of the vibrator 7, and is supplied to the pool hopper 9 from the tip side thereof, and then the weighing hopper 11 Are supplied to the device and are subjected to a predetermined combination weighing.

Then, when the vibrator 7 vibrates in a predetermined cycle,
The product 20 supplied on the trough 8 by the vibration of the trough 8 in the front-rear direction via the leaf springs 18, 18 is repeatedly dropped and flipped up by the cycle vibration of the trough 8 in a cycle. It is conveyed in the direction of the arrow and supplied to the next-stage pool hopper.

Therefore, although the product 20 is supplied and conveyed by the vibration of the trough 8 in the front-rear direction by the vibrator 7, the trough 8 is vibrated in the longitudinal direction by aligning the extending posture with the front-rear vibration direction of the vibrator 7. As a result, uniform vibration in the front-rear direction is applied to the entire area of the trough 8, so that the solid product 20 such as the twist-wrapping candy that has been thrown in at the base of the trough 8 has a uniform drop action. Due to the bounce-up action, there is a phenomenon in which it is fed in a random posture during the transport process and is transported in an overlapping posture not only in the front-back direction and the width direction but also in the vertical direction. As described above, there is a drawback in that it is not possible to supply the desired individual products in line, such as expensive chocolate twist packaging candy, and the light in the transportation process. Aligning and supplying the count through the sensor or the like is hardly possible, therefore, there is a drawback that it is difficult can transport supply adjustment control of the product.

Therefore, as a matter of course, there is an inconvenience that the package may be hindered by measuring the quantity of the product 20 such as a desired twist packaging candy in the packaging process in the final step.

<Purpose of Invention> The purpose of the invention of this application is to solve the problems of the above-mentioned conventional technique of conveying expensive chocolate in a twisted packaging candy in a number-aligned state and subsequent quantitative weighing. In the product supply process from the product insertion section to the pool hopper, expensive products such as the seed twist packaging candies can be more reliably fed in a serial alignment posture, and the quantitative measurement of the seed products etc. can be reliably designed. The purpose of the present invention is to provide an excellent quantitative weighing device which can be performed as described above and which is beneficial to the field of application of weighing technology in the distribution industry.

<Means and Actions for Solving the Problems> In order to solve the above-mentioned problems, the structure of the invention of the present application, which is based on the above-mentioned object and has the scope of the above-mentioned utility model registration request,
When measuring the number of solid products such as the product insertion part and quantitatively measuring the weight, the product insertion part provided on the upper part of the frame of the quantitative weighing device is made into a so-called parts feeder type dispersion ball, and the vertical direction, and, The products are arranged so as to vibrate in the circumferential direction integrally in a predetermined cycle, and the peripheral wall portion is provided with a predetermined number of discharge ports. When the shutter is operated to open and close, it is supplied to the transfer troughs of the respective heads which are set in a mutually parallel posture through the chute, and each of the transfer troughs is vibrated in the front-back direction by the vibrator provided at the base of the apparatus frame. The product fed through the is forwarded, but the transport trough is formed in a U-shaped cross section and is installed in a posture intersecting the vibration direction by a predetermined angle in plan view. As a result, the two inner surfaces generate vectors in opposite directions on the opposite sides, so that the goods being conveyed are forcefully statically aligned and are subjected to the alignment action when the inner bottom is advanced. The individual products can be counted individually, and the products are put into the pool hopper of each head from the tip thereof, and at the base end of the transfer trough by a detection device such as a photoelectric sensor provided at the base end of the transfer trough. When the absence state of the product is detected, the shutter of the outlet of the dispersion ball is opened, the product in the dispersion ball is supplied to the transfer trough through the chute, and the dispersion ball is synchronized with the opening and closing of the shutter. The vibrator of the product vibrates, and the products in the dispersion ball are supplied from the discharge port to the transport trough through the chute, and a detection device such as a photoelectric sensor provided at the tip of the transport trough is used to transport the product. When the absence of the product to be supplied from the tip to the pool hopper is detected, the transfer trough is vibrated by the vibrator until the next product is detected.In this case, the vibration of the transfer trough is also controlled by the timer, etc. The number of products supplied to the hopper is also quantitatively measured by the detection device, and further, the weight is detected from the pool hopper to the weighing hopper at the lower stage and the weight is detected by the load cell, etc. Is calculated and the lid is opened, and is conveyed to the next packaging process by the conveyor through the collecting chute. Therefore, the set weight for each quantitative measurement by the above process, or, This is a technical measure that ensures that the same product weight and the number of products are weighed.

<Embodiment> Next, referring to FIG. 21, one embodiment of the invention of this application,

It should be noted that parts that are the same as those in FIGS.

In the embodiment shown in FIG. 1, reference numeral 1'is a control device, which is provided with a control panel similar to a general embodiment such as a numeric keypad on the upper part, and a quantitative measurement which is the center of the gist of the invention of this application via a cable 16 '. It is electrically connected to the combination weighing device 2'of the device.

The combination weighing device 2'performs a predetermined combination weighing while quantitatively weighing a set quantity of a plurality of types of expensive to inexpensive candies 20 in a pack. In a compact type combination weighing device 2'as shown in FIGS. 4 and 5, a relatively expensive product 20 such as a twist packaging candy of chocolate or the like has a relatively heavier unit weight than other products. It is used for quantitative measurement and is adapted to be connected to the next packaging process, and a type of hermetically sealed housing is formed by the removable panel 3 with respect to the cubic type rectangular frame 4. Is being done.

Then, inside the housing, the respective mechanical parts are integrated and adjacent spaces are provided as close as possible to each other, and a cable 16 'connected to the panel 3 at the bottom from the control device 1'.
Signals to and from the power source and the control unit are transmitted and received via the.

A dispersion ball 5'as a product supply unit is provided along one side of the frame 4 near one side of the upper part so that the panel 3 can be inserted therethrough. Head, 6 in this embodiment
Head (for convenience of illustration, the numbers are different in FIGS. 1, 4, and 8)
Dispersing balls 5 ', 5'through shoots 6', 6 '...
Are connected to the respective supply troughs 8 ', 8' ... which extend to the other side of the frame 4 in a direction intersecting with each other in a predetermined manner.

As shown in FIGS. 1 and 2, the troughs 8 ′ are arranged in a parallel posture as close to each other as possible, and each of the troughs 8 ′ is provided on the frame 4 and is a well-known electromagnetic wave as a vibrator. It is placed and supported and fixed on the vibration device 7, and its tip is connected to the pool hopper 9, respectively.

Each pool hopper 9 is provided near the other side of the housing and has a built-in rotary solenoid as a drive device (not shown) and is mounted on the frame 4 so that it can be freely attached and detached in a predetermined manner. , 9 are arranged in parallel on the other side of the frame 4 and are provided in positions and postures as close to each other as possible.

Thus, each pool hopper 9 has a pair of opening / closing lids 12 and 12 which are opened / closed in a direction parallel to the trough 8 ', and each of which is provided with a tension spring (not shown) as shown in FIG. Are urged so as to occlude each other, and are opened and closed by a rotary solenoid (not shown) in the frame 4 via a link.

Therefore, each opening / closing lid 12 of each pool hopper 9 is always kept in a closed posture by one tension spring regardless of whether the other is opened or closed.

The pair of open / close lids 12 and 12 of the pool hopper 9 are alternately opened and closed by a microcomputer and a control relay (not shown) in the frame 4, and when one side is opened and closed, the other side is not opened and closed. , The closed lid 12 opens as a kind of chute, the lower weighing hoppers 11, 11
It is designed to introduce 20 products.

Under the pool hoppers 9, the open / close lids 12, 12 are provided.
In the opening / closing direction, that is, in a posture substantially along the supply trough 8 ', a pair of weighing hoppers 11, 11 are provided for each opening / closing lid 12, and each opening / closing lid 13 is orthogonal to the opening / closing lid 12 of the pool hopper 9. The weighing hoppers 11 are opened and closed in a direction along the frame 4, and all of them are opened and closed only in one direction. The weighing hoppers 11 are arranged so as to be inclined sufficiently inward in a closed posture so that the postures do not interfere with each other and the positions and postures of the respective weighing hoppers 11 are close to each other at a minute interval.

The frame 4 on the same side as the dispersion balls 5'is provided below the vibrator 7 of the electromagnetic vibration device on the lower side of each trough 8 '.
As shown in FIG. 5, the square load cells 10, 10 are provided on the side surface of the frame 4 in parallel to the outer side surface, and in the same manner as in the conventional mode, the load cells 10, 10 are vertically arranged in two stages at the same level on one side of the frame 4. To the other side in parallel with each other, the supporting arms for the weighing hoppers 11 are attached to the respective load cells 10 every other one in the up and down reverse postures via the bolts, respectively, and the directions perpendicular to the tips thereof are provided. The weighing hoppers 11 are supported in parallel with each other through the brackets extending in the same posture.

Therefore, even if the distance between the respective weighing hoppers 11 is narrowed, the mounting of the corresponding load cells 10 does not interfere with each other.

A gutter-shaped collecting chute 14 is provided on the outer side of the frame 4 for all of the inner and outer weighing hoppers 11 and on the side opposite to the dispersing balls 5'in parallel therewith. A discharge port 15 which is opened at the end is connected to the next stage of the packaging process (not shown) via a conveyor.

Thus, as shown in FIGS. 10 to 12, the vibrating product transporting device 17 'has a trough 8'having a substantially U-shaped cross section from the starting end to the leading end of the trough 8'. The outer bottom surface in the middle is connected to the device frame 4 via the bracket 19 '.
Is fixed to a pair of front and rear vibrating leaf springs 18, 18 which are erected via a base 4 ', and is opposed to the electromagnetic coil 7'on the base 4'. 7 "is attracted to and separated from the electromagnetic coil 7'to vibrate the trough 8 '.

Thus, the fixed state of the trough 8'is such that the longitudinal direction of the trough 8'is 12th with respect to the vibration direction of the front and rear of the hybrator 7.
As shown in the figure, they are set so that they intersect at a predetermined angle θ on the horizontal plane.

And, as described above, the base of the trough 8'is connected to the dispersion ball 5'through the chute 6 ',
At the mating portion with the chute 6 ', a light emitting diode 25' and a phototransistor 26 of a detection device of a photoelectric sensor are provided in opposition to count the number of feeds from the chute 6'of the twist packaging candy 20 to the trough 8 '. It is designed so that it can be detected.

The principle operation of the vibrating product conveying device 17 'will be described. When the vibrator 7 vibrates in the front-rear direction in a predetermined cycle, the trough 8'will move through the leaf springs 18 and 18 and the bracket 19'. 7 vibrates synchronously in the front-back direction, but as shown in FIG. 10 (a) and FIG. 12, the trough 8 ′ has a horizontal plane in which the front-back vibration direction of the vibrator 7 and its longitudinal direction are in plan view. Since it intersects at an inclination angle of θ, the inclination position a to the left and right in plan view from the center line, up and down for one cycle of the trough 8 ′ at b, and
As shown in FIG. 11, the flip-up vectors f and f'are completely eliminated in the tilting action of the twist packaging candy 20 after falling due to the tilt vibration in the front-rear direction, as shown in FIG. As a result, in successive cycles, the vectors f and f'in the left and right slanted portions of FIGS. 11 and 12 are opposite to each other. Therefore, in the portion of FIG. In the portion B, the urging force in the rearward direction is applied and the front and rear are individually aligned and supplied. Therefore, even if the twist packaging candies 20 fed from the chute 6'to the base are overlapped in the front and rear direction and the width direction. The troughs 8'are aligned and supplied by the opposite biasing forces of the vectors f and f'in the left and right portions of the inner inclined surface of the trough 8 ', and thus the inner bottom portion of the trough 8' Transport professional to the tip In the process, the individual pieces are surely subjected to the aligned supply operation, and when they are thrown into the pool hopper 9 from the tip end, they are surely individually thrown into the aligned supply shape one by one.

Although the trough 8'has an inverse relationship between the aligning supply action and the conveying action with respect to the twist packaging candy 20, the trough 8'for the vibrator 7 is preliminarily considered in consideration of the aligning supply function and the convey function depending on the product. The crossing angle of should be set.

Therefore, the trough 8'can be attached to the vibrator 7 via the bracket 19 'and the leaf springs 18 and 18 by screwing so that the crossing angle can be adjusted.

In each of the dispersion balls 5 ', as shown in FIGS. 2 and 3, a predetermined number of 3 to 3 is provided near the front side of the circular peripheral wall portion 21.
Four discharge ports 22, 22, 22, 22 are provided by opening, and each discharge port 22 is appropriately attached to the peripheral wall 21 as shown in FIGS. An open / close shutter 25 made of Duracon is provided by a solenoid 23 via a link 24 so as to be opened and closed so as to be exposed to the base of the chute 6 ', the joint between the chute 6'and the transfer trough 8', and the transfer trough. The shutter 25 can be freely opened and closed via the control device 1'by the photoelectric sensors 26, 26 'provided at the tip of 8', and the vibrator 7 vibrates in the circumferential direction and vertically in a predetermined cycle which vibrates in a predetermined cycle. A product 20 such as a twist packaging candy can be fed from the chute 6'to the transport trough 8'from 5 '.

In this embodiment, each discharge port 22 provided in the peripheral wall 21 of the dispersion ball 5'is made slightly larger than the cross-sectional size of the product 20, and as shown in FIG. The product 20 can be smoothly discharged to the chute 6'when the product 20 is placed in the longitudinal posture by the vibration in the direction, and the chute 6'at the base end of the transport trough 8'can be discharged. When the absence of the product 20 at the base end of the transport trough 8'is detected by the photoelectric sensors 25 'and 26 provided at the joining portion, the solenoid 23 detects the next product 20 for a certain period of time. The shutter 25 is opened and closed, and the product 20 in the dispersion ball 5'is discharged and supplied from the chute 6'through the discharge port 22 to the transport trough 8'by vibrating in the circumferential direction and in the vertical direction. .

Further, in synchronization with the opening / closing operation of the shutter 25, the dispersion balls 5 '
The vibrator 7 is also energized to vibrate the dispersion balls 5'in the circumferential direction and in the vertical direction. However, as shown in FIG. 6, one of the shutters 25, 25 ... The start-up current 5 "of the dispersion balls 5'is pre-programmed so that it is energized when 'is energized.

Thus, the photoelectric sensor 26 'provided at the tip of the transport trough 8'will supply the commodity 20 to the pool hopper 9 when the commodity 20 is opened due to the combined weighing selection operation. Although the vibrator 7 of the trough 8'is vibrated, as shown in FIG. 7, when the control signal from the lid body control device 1'of the pool hopper 9 is input, the timer signal 7 "is activated for a predetermined time and the vibrator 7'is activated. 7 vibrates, but even if the timer signal 7 ″ ends, if the photoelectric sensor 26 ′ outputs the absence signal 26 ″ of the product 20, the vibrator 7 of the trough 8 ′.
The energization signal 8 ″ is further controlled to output a control signal to excite the vibrator 7.

In the above-mentioned configuration, when the twist-wrapped chocolate products 20 which are dispersed in a uniform amount with time by a wide belt conveyor (not shown) are continuously fed, the dropped chocolate products 20 are dispersed balls. 5'and 5'are uniformly charged in time, and are supplied from the discharge ports 22, 22 ... through the chutes 6 ', 6' ... for each head by three-dimensional vibration in the circumferential direction and in the vertical direction. Trough 8 ',
8 ', 8' ..., are continuously advanced by the respective vibrators 7, dropped into the corresponding pool hoppers 9, respectively, and the commodities 20 supplied to the respective pool hoppers 9 are dispersed balls 5 '. Opening / closing lid 12 via a link by a rotary solenoid provided in the frame 4 on the opposite side to the side,
12 are alternately opened and closed, and the open / close lid 12 that has not been opened and closed is thrown into the weighing hopper 11 connected to the lower side as a chute.

Incidentally, electric instrumentation such as a microcomputer and a control relay is housed in the frame 4.

Then, in each weighing hopper 11, the weight thereof is measured via the arm by the load cell 10 provided in the frame 4, and the measured weight can be combined by a high-speed calculation by a microcomputer as in the conventional mode. The rotary solenoid provided in the frame 4 is driven for the weighing hopper 11 whose selected weight value has been added to the combination of the plus minimum amount, and the link is operated to open / close the corresponding opening / closing lid 13. Weighing hopper for combination 11
Products are discharged to the collecting chute 14 and transferred from the lower discharge port 15 to the next package process via the conveyor.

Therefore, the control operation of the combination weighing is substantially the same as the combination weighing of the conventional combination weighing device.

During this period, the supply troughs 8 ′, the pool hoppers 9, and the weighing hoppers 11 are in the postures in which they are alternately brought close to each other within the frame 4, but their operations are not hindered and the opening / closing lid 12 of the pool hopper 9 is not disturbed. , 12 and opening / closing of the opening / closing lid 13 of the weighing hopper 11 are smoothly operated without being hindered by the alternating proximity intervals.

During this time, the twist-wrapping candy 20 supplied from the dispersing balls 5'to the troughs 8'through the chutes 6 is vibrated in the front-back direction by the vibration of the vibrators 7 in the front-back direction, as described above. In the longitudinal direction, the parts of the left and right inclined surfaces are a, and in b, the vector f at the time of flipping up,
Since f'is reversed, the left and right are aligned by receiving the front and rear direction aligning and feeding action, and are individually forwarded in the state of being individually aligned on the inner bottom surface thereof and fed into the pool hopper 9 one by one, The overlapped state and the random attitude supply are avoided, and the supply is performed for the aligned supply. During this time, the number of the supply from the chute 6'to the trough 8'is the detection device 2 of the photoelectric sensor.
The vibrator 7 vibrates by a timer for a predetermined time detected by the control devices (not shown) detected by 5 ', 26, and reliably supplies the twist-wrapping candy 20 aligned and supplied to the pool hopper 9. .

Then, the group of twist-wrapping candies 20 combined and weighed from the weighing hopper 11 by the microcomputer is discharged from the discharge port 15 to the next-stage package through the collecting chute 14.

It should be noted that the embodiment of the invention of this application is not limited to the above-mentioned embodiment, and for example, regarding the crossing angle in the horizontal plane with respect to the traveling direction of the goods of the transfer trough on the upper surface of the vibrator of the transfer trough, Although it may be fixed to the set angle, various modes such as adjusting screw fixing type so that the crossing angle can be freely changed can be adopted.

Furthermore, it goes without saying that it can also be used for a quantitative weighing device that does not rely on a combination.

<Effects of the Invention> As described above, according to the invention of this application, the product troughs provided on the upper part of the apparatus frame have the transfer troughs which are provided in parallel to each other through the chutes of the predetermined number of heads.
In a compact type quantitative weighing device in which the transport trough is connected to a weighing hopper via a pool hopper,
The product loading section is made into a parts feeder type dispersion ball having a predetermined number of discharge ports connected to a predetermined number of head chutes, and transfer troughs provided in parallel through the chutes vibrate on the vibrator. Since it is formed in a U-shaped cross-section that intersects the direction at a predetermined angle in plan view, products such as twist packaging candy supplied in the dispersion ball can be longer than the size of the discharge port. Even if it has one, first, since it is discharged from the discharge port to the chute with a cross section corresponding to the size of the discharge port, it is primarily regulated and discharged in the aligned state,
Further, the vibrators are aligned and forwardly fed in a posture that does not overlap each other by the transfer troughs having a U-shaped cross section that are inclined in the vibration direction at a set angle in plan view and intersect.
Therefore, secondarily, it becomes possible to supply a predetermined number of pieces when it is discharged to the weighing hopper through the pool hopper and quantitatively weighed by the attitude control alignment action, and the predetermined number of pieces can be controlled and controlled in the quantitative weighing. As a result, not only the overall weight measurement but also multiple processing can be performed, which is an excellent effect.

Therefore, there is an advantage in product processing that price adjustment and the like can be performed as designed when packaging a combination of an expensive product and an inexpensive product.

Thus, it is possible to provide a shutter at the discharge port of the dispersion balls and a product detection sensor such as a photoelectric sensor on at least one of the base portion and the tip portion of the transport trough so that control can be performed via the control device. Therefore, there is an effect that the counting management can be performed more reliably by design, and an excellent effect that the above-described regulation control supply / conveyance is performed more reliably is achieved.

Also, since the product can be supplied and transported by the transport trough from the dispersion ball to the pool hopper while the posture of the product itself is controlled, the mutual arrangement of the chute and the transport trough can be made more compact and compact, and the overall size and size of the device can be reduced. There is also an effect that the installation space can be effectively used because the excellent effect that it can be achieved is achieved, the compatibility with peripheral devices is good, and the installation space can be effectively used.
