In this example, as shown in FIGS. 1 and 4, 16 measuring units 3 in each row are arranged in a row, and a total of 32 measuring units 3 are provided in two rows in front and back. The number of reams constituting the plurality of reams is arbitrary, and may be a number according to the number of varieties of articles to be mixed and the like.

Weighing is performed on the front side of the weighing unit 3 group on the front side (left side in FIGS. 2 to 4) and on the rear side (right side in FIGS. 2 to 4) of the measuring unit 3 group on the rear surface side. Supply units 4 for supplying various kinds of articles to the upper part of each measuring unit 3 arranged in a straight line are arranged close to each other facing the measuring unit group 3.

Each series of measuring units 3 includes a supply hopper 5 that temporarily holds and discharges the articles conveyed from the supply unit 4, a measuring hopper 6 for holding and weighing the articles discharged from the supply hopper 5. The structure is such that the memory hopper 7 for holding the article discharged from the weighing hopper 6 is arranged in a vertical column. Each of the hoppers 5, 6 and 7 of the measuring unit 3 is detachably attached to the center substrate 1 in the same manner as in the conventional case.

Although not shown, a weight sensor described later for detecting the weight of an article supplied to the gate drive unit that opens and closes the discharge gate of the supply hopper 5, the weighing hopper 6, and the memory hopper 7 and the weighing hopper 6. Etc. are stored and supported in the center substrate 1. The center substrate 1 and each supply unit 4 are connected by a cable or the like (not shown).

Each measuring unit 3 is provided with a memory hopper 7 as described above, and the number of hoppers (effective hoppers) that can participate in the combination calculation can be increased.

In this embodiment, as shown in FIG. 1, the measuring unit 3 having 16 stations in each of the front and rear rows is composed of four partial stations divided into four groups adjacent to each other in the left-right direction, and is composed of four partial stations on the left and right outer sides. The two partial reams are located higher than the two inner reams.

Below the weighing hopper 6 and the memory hopper 7 in each partial series, a plurality of weighing hoppers 6 selected by a combination operation so as to have a predetermined weight, or a first set for collecting articles discharged from the memory hopper 7. Shoot 8 is deployed.

Below each first set chute 8 corresponding to each partial series, a first gate 9 for opening and closing the discharge port of each first set chute 8 is provided, and articles collected by each first set chute 8 are provided. Can be temporarily received, held, and discharged. Further, below the plurality of first gates 9, a single second collective chute 10 and a second collective chute 10 that slide down and guide the articles discharged from each first collective chute 8 and collect them in the lower center of the measuring unit 3 group. A second gate 11 is provided to open and close the central discharge port of the collecting chute 10. All kinds of articles weighed and collected by the front and rear weighing units 3 groups are collected in one place in the center of the second collecting chute 10, temporarily received and held by the second gate 11, and held in the second. 2 The gate 11 is opened and discharged to the lower packaging machine. The second gate 11 is open-controlled based on a discharge request command from the packaging machine side.

At speed, it can slide down along each of the collective gates 8 and 10.

The supply unit 4 corresponds to one for each of the two sub-reams, the outer sub-ream in the left-right direction and the inner sub-ream adjacent to the outer sub-ream, and each sub-ream is composed of four reams. The article is supplied to the measuring unit 3 for eight stations by the supply unit 4 of the table. Therefore, a total of four supply units 4 are arranged in parallel on the left and right, two in front of the three groups of measuring units in one row on the front side and two in the rear of the three groups of measuring units in one row on the rear side. ing.

In the supply unit 4, four storage hoppers 13 having different heights for accommodating the articles are placed on the upper part of the underframe 12, and a total of eight storage hoppers 13 and articles drawn from the lower ends of the storage hoppers 13 are directed toward the measuring unit 3. It is configured to be equipped with a total of eight supply feeders 14, four with different heights for vibrating and transporting.

Each supply feeder 14 separately vibrates and drives two first and second linear feeders 14a and 14b arranged in parallel in a step-down manner along the transport direction of the article. It is composed of vibration mechanisms 15a and 15b. By configuring the supply feeder 14 with the two first and second linear feeders 14a and 14b in this way, the transport distance for vibrating and transporting the article is lengthened, and the article is leveled and supplied little by little between them. It can be used for a wide variety of small quantities and is suitable for weighing.

Further, since the vibration intensity (amplitude) can be set for each of the linear feeders 14a and 14b, an appropriate vibration intensity can be set according to the type of the article.

The articles charged and supplied from the storage hopper 13 to the first linear feeder 14a on the upstream side in the transport direction are loosened while being vibrated and transported, transferred to the second linear feeder 14b on the downstream side, and vibrated by the second linear feeder 14b. It is conveyed and sent little by little to the supply hopper 5 of the measuring unit 3. Further, when the supply feeder 14 vibrates and conveys, the lump of the article is easily loosened by an appropriate drop impact at the step portion between the first linear feeder 14a and the second linear feeder 14b formed in the transport path.

Above each supply feeder 14, for example, an article detection sensor 16 that detects the stacking height of articles near the end of the first linear feeder 14a on the upstream side by ultrasonic waves is provided, and the detection output thereof is Based on this, the vibration strength and the like of the vibration mechanisms 15a and 15b are controlled by the control device described later, and the articles are supplied to the measuring unit 3 little by little.

Wheels 17 are provided at the lower four corners of the underframe 12 in the supply unit 4, and rails 18 for engaging and guiding the wheels 17 are laid along the front-rear direction on the floor surface 2. Each supply unit 4 can move approaching and separating from the measuring unit 3 group in the row direction along the rail 18 in a direction orthogonal to the measuring unit 3 group.

That is, as shown in FIGS. 3 and 4, the supply unit 4 is largely moved outward from the supply position for supplying the article to the measuring unit 3, and the operator is placed between the supply unit 4 and the measuring unit 3. By opening a space for the hoppers, the hoppers 5, 6 and 7 of the measuring unit 3 and the members of the supply unit 4 can be easily attached and detached for cleaning and inspection and maintenance.

When the supply unit 4 is moved closer to the measuring unit 3 group after cleaning work, inspection and maintenance, etc., it is supplied by moving the supply unit 4 closer to the stopper 19 projecting near the rail 18 until the underframe 12 comes into contact with the stopper 19. The end of the feeder 14 will be properly positioned with respect to the supply hopper 5. At this positioned supply position, the supply unit 4 is appropriately fixed by the locking means and the weighing operation is started.

In this embodiment, by moving one supply unit 4 apart, the front surface of the eight measuring units 3 can be opened, and one supply unit 4 faces the one measuring unit 3. Cleaning work, inspection and maintenance, etc. will be easier than when deploying. If one supply unit 4 is arranged to face the three groups of measuring units in a row, in this example, 16 consecutive measuring units 3, the weight of the supply unit 4 becomes large and it becomes rather difficult to handle. ..

The supply feeder 14 that vibrates and conveys the article to the supply hopper 5 of the weighing unit 3 is provided on the underframe 12 of the supply unit 4, while the weight sensor that detects the weight of the article supplied to the weighing hopper 6 of the weighing unit 3 is a weight sensor. The weight sensor provided on the center substrate 1, that is, the weight sensor for detecting the weight of the article, and the supply feeder 14 for vibrating and transporting the article are provided in different housings 1 and 12, respectively. As a result, as in Patent Document 1, the distributed feeder and the linear feeder that vibrate and convey the article to the supply hopper become the center substrate having the same housing as the weight sensor that detects the weight of the article supplied to the measuring hopper. Compared to the configuration provided, the weight sensor can reduce the influence of vibration received from the feeder.

FIG. 5 is a control block diagram of the weighing device according to this embodiment.

The control device 41 that controls each unit is housed in, for example, the center substrate 1 and is connected to an operation setting display 42 that displays various settings such as operations for the measuring device, operation parameters, and measured values. .. The control device 41 is given a detection output of the article detection sensor 16 of the supply unit 4 and a weight signal from a plurality of weight sensors 40 housed in the center substrate 1. The control device 41 controls the drive of the linear feeders 14a and 14b of the supply unit 4, and also controls the opening and closing of the discharge gates of the hoppers 5, 6 and 7 and the first and second gates 9 and 11.

The control device 41 has a function as a calculation control unit 43 that performs a combination calculation based on the weights of the articles of the weighing hopper 6 and the memory hopper 7 and discharges the articles from the hoppers 6 and 7 selected for the appropriate amount combination. However, when the weight of the article supplied to the weighing hopper 6 is an excessive amount exceeding a predetermined weight range, the arithmetic control unit 43 controls the exit / exit operation of the reject chute 21 by the reject mechanism 20 as described later. And eliminate excess goods.

The control device 41 does not necessarily have to be composed of a single control device, but may be composed of a plurality of control devices that cooperate with each other to perform distributed control, and the center substrate 1 and the supply unit on the measuring unit 3 side may be configured. It may be provided in each of 4.

As shown in FIGS. 2 and 3, the underframe 12 of the supply unit 4 is provided with a reject mechanism 20 for discharging an excessive amount of articles supplied to the measuring hopper 6.

FIG. 6 is a side view showing the measuring unit 3 and the reject mechanism 20.

The lower end of the weighing hopper 6 is provided with an outer gate 6a and an inner gate 6b for discharging that can be independently opened and closed. It is sent directly to the lower first set chute 8 via the first delivery path (a), and by swinging open only the inner gate 6b inward, the weighed article is sent through the second delivery path (b). It is sent to the memory hopper 7 and temporarily held.

That is, the measuring hopper 6 can selectively discharge the held article in two different discharge directions, and the discharged article is the first delivery path (a) which is two routes, or the discharged article. It is transmitted to the first set chute 8 or the memory hopper 7 through the second transmission path (b).

When the weight of the article supplied to the weighing hopper 6 is an excess exceeding a predetermined weight range, the reject mechanism 20 for eliminating the excess article moves the reject chute 21 and the reject mechanism 20 forward and backward horizontally. An air cylinder 22 as a drive mechanism is provided, and a collection container 23 for collecting articles thrown into the reject chute 21 is provided.

The reject chute 21 is arranged so as to face the first delivery path (a) of the measuring hopper 6 from the outside. Normally, as shown in FIG. 6, the air cylinder 22 is shortened and the reject chute 21 is retracted to the outside of the first delivery path (a), and the article is associated with the opening of the outer gate 6a of the measuring hopper 6. Does not prevent the discharge to the first collective chute 8.

When the weight of the article weighed by the weighing hopper 6 is an excess exceeding a predetermined weight range, as shown in FIG. 7, the air cylinder 22 is extended and the reject chute 21 is set to the first delivery path (a). ) Will be rejected. In this state, when the outer gate 6a is opened, the excess articles in the measuring hopper 6 are discharged to the cylindrical reject chute 21 having the input port and the discharge port, and the excess articles are discharged to the collection container 23. It is collected by flowing down. When the collection is completed, the reject chute 21 returns to the original position retracted from the first delivery path (a), and the outer gate 6a of the measuring hopper 6 is closed to prepare for the supply of the next article. The collection container 23 is provided so that an excessive amount of articles can be collected for each variety so that articles of different varieties are not mixed. As a result, the recovered article can be efficiently and efficiently re-weighed without waste.

A guide member 24 made of a plate material is provided at the tip of the reject chute 21. The guide member 24 is located at a position facing the first delivery path (a) from the outside when the reject chute 21 is at a position retracted outward from the first delivery path (a), and is outside the weighing hopper 6. The gate 6a is opened to prevent the discharged article from scattering to the outside by the guide member 24, and the discharged article is correctly guided to the first collective chute 8.

As shown in FIG. 1, since the storage hopper 13 provided in the supply unit 4 is deployed at a relatively high position for the operator, in order to easily replenish the article, the article supply position at the high position and the article supply position are set. It is convenient to configure it so that it can be switched up and down to a low position for supplying goods.

An example of the elevating structure of the storage hopper 13 is shown in FIG. In this example, the storage hopper 13 having the article supply port 13b at the upper corner slides up and down on the support bracket 31 provided on the underframe 12 via the vertical elongated holes 32 and the two pins 33a and 33b, and inside and outside. It is supported so that it can be reversed and rotated.

That is, a bifurcated bent hole portion is formed in the upper part of the elongated hole 32, and the pins 33a and 33b are supported by the end portions of the bent hole in a state where the storage hopper 13 is raised. As a result, the storage hopper 13 is stably held at the article supply position that stands upright on the starting end of the supply feeder 14. From this state, when the storage hopper 13 is rotated outward by 90 degrees around the pin 33a and then pulled out slightly outward, both the pins 33a and 33b are located at the straight portions of the upper and lower elongated holes 32. As a result, the storage hopper 13 in the posture of being turned outward can be lowered in the same posture by the guidance of both pins 33a and 33b and the upper and lower elongated holes 32.

The lowering limit becomes the article supply position at a low position, and the article supply and cleaning of the storage hopper 13 to the article supply port 13b can be easily performed. In addition, a telescopic damper 34 is erected over the storage hopper 13 and the lower part of the support bracket 31 to provide appropriate resistance to the rotation and lowering of the storage hopper 13 and to assist the hopper lifting operation. There is. The handle 13a used for the position switching operation of the storage hopper 13 is provided over two adjacent storage hoppers 13, and the position switching operation of the storage hopper 13 is performed by two units at a time.

In this way, after the storage hopper 13 is lowered and replenished easily at a low position, the storage hopper 13 can be set to a predetermined article supply position simply by lifting the storage hopper 13, for example, to a storage hopper fixed at a high position. The replenishment work becomes easier than when replenishing by lifting a replenishment container or the like.

In this embodiment, a large number of varieties, for example, 10 varieties of articles are mixed and weighed. Reams are appropriately assigned to each, and the reams for each type assigned to the control device 42 are registered by operating the operation setting display 42. Articles of the corresponding varieties are stored in the storage hopper 13 of the supply unit 4 corresponding to each of the registered measuring units 3 and operated.

The calculation control unit 43 of the control device 41 performs a combination calculation based on the weights of the articles of each type of the weighing hopper 6 and the memory hopper 7 of the measuring unit 3 corresponding to the articles of each type. This combination operation is not particularly limited, and a conventionally known combination operation of mixed weighing may be performed. For example, the hopper to be discharged is determined for 9 kinds of articles from the 1st to 9th varieties within a predetermined weight range, and the weight added to the total weight of the 9 varieties of articles is the lower limit of the target combination weight. The hoppers of the tenth kind of articles that are within the allowable weight range are selected, and the hoppers of the nine kinds of articles determined and the hoppers of the selected tenth kind of articles are used as hoppers of an appropriate amount combination, and from the hoppers of this appropriate amount combination. The article is discharged and put into the packaging machine through the first collecting chute 8, the first gate 9, the second collecting chute 10 and the second gate 11.

As a result, the mixed article in which 10 kinds of articles whose total weight is within the allowable weight range is mixed is packaged in the packaging machine.

As described above, according to the present embodiment, a plurality of measuring units 3 having a supply hopper 5 and a measuring hopper 6 in a series are arranged in a row so that the supply hoppers 5 are arranged in a straight line, and each supply is provided. Since the supply unit 4 for supplying the article to the hopper 5 is arranged close to each other so as to face the plurality of measuring units 3, for example, when the variety of the article to be supplied to the supply hopper 5 is diverse. If it is desired to increase the number of stations constituting the plurality of measuring units 3, the measuring units 3 and the supply units 4 arranged in a straight line may be added in a straight line, as in Patent Document 1 above. It is not necessary to increase the diameter of the distributed feeder to expand the occupied space in all directions around the distributed feeder, and the size is compact in a plane.

Further, since a plurality of stations of the measuring units 3 are provided on both sides of the center substrate 1 and the supply units 4 corresponding to each row are arranged in close proximity to the plurality of stations of the measuring unit 3, the same number of stations is provided. The measuring unit 3 and the supply unit 4 can be arranged in an integrated manner by shortening the length in the row direction and effectively utilizing the plane space, as compared with the case where the above is composed of only one row.
