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

[Embodiment 1]
FIG. 1 is a vertical sectional front view showing a schematic configuration of a combination scale according to an embodiment of the present invention, FIG. 2 is a plan view of the vicinity of an assembly funnel, which is a main part thereof, and FIG. It is a perspective view of.

The combination scale of this embodiment is a packaging line that weighs and discharges a predetermined amount of objects to be weighed such as various confectioneries and foods, and puts the weighed objects into a packaging device and packs them in a bag. Used for.

In this combination scale, a hollow center base 2 is supported via a support leg 3 above a base 1 having a hollow structure having a large central portion and a vertical opening. A dispersion feeder 4 is provided at the center of the upper part of the center substrate 2 to radially disperse and convey an object to be measured that is dropped and supplied from the end of a supply device (not shown) by vibration. Around the dispersion feeder 4, a large number of linear feeders 5 that linearly convey the dispersed and transported object to be measured outward by vibration are provided radially.

Further, a supply hopper 6 that temporarily stores and discharges the objects to be measured from each linear feeder 5 on the outer peripheral wall of the center substrate 2, and a metering that measures and discharges the objects to be measured discharged from each supply hopper 6. The hopper 7 and the hopper 7 are arranged in a circle around the center substrate 2. The combination weighing and discharging of the object to be measured is performed by a large number of measuring units (for example, 24 stations) including the linear feeder 5, the supply hopper 6, and the measuring hopper 7.

Below each measuring hopper 7, a collecting chute 8 is provided that collects and discharges the discharged objects to be measured below the center side of the center substrate 2. The collecting chute 8 is an inverted truncated cone-shaped tubular body having a small diameter downward, and is composed of a plurality of, in this example, eight collecting chute 8.

At the lower end of the collecting chute 8, a tubular collecting funnel 9 that collects the objects to be measured that have slid down from the collecting chute 8 below the center side of the center substrate 2 is provided. The collecting funnel 9 is an inverted truncated cone-shaped tubular body having a smaller diameter downward.

Below the collecting funnel 9, a collecting hopper 10 that temporarily receives and stores the objects to be measured collected by the collecting funnel 9 is arranged, and based on a discharge request command from a packaging device (not shown) installed below. The opening / closing control of the pair of gates 10a of the assembly hopper 10 is performed by a control device (not shown).

The dispersion feeder 4 includes a top cone 11 and an electromagnetic vibration mechanism 12 that vibrates and drives the top cone 11. The vibration mechanism 12 is arranged inside the center substrate 2. The vibration mechanism 12 is connected and supported by the weight sensor 13. The weight sensor 13 detects the weight of the object to be weighed on the dispersion feeder 4. Then, the supply device is controlled based on the weight detection information so that the object to be weighed within the set range is always supplied onto the distributed feeder 4.

The linear feeder 5 includes a gutter-shaped trough 14 and an electromagnetic vibration mechanism 15 that vibrates and drives the trough 14. The vibration mechanism 15 of each linear feeder 5 is arranged inside the center substrate 2 so as to surround the vibration mechanism 12 of the distributed feeder 4.

On the outer peripheral portion of the center base 2, a drive unit 16 incorporating a drive mechanism for opening and closing the gates of the supply hopper 6 and the measuring hopper 7, a weight sensor for measuring the weight of the object to be weighed in the measuring hopper 7, and the like is incorporated. The supply hopper 6 and the measuring hopper 7 are detachably attached and supported by a hook method at the outwardly exposed portion of the drive unit 16.

The combination scale of this embodiment makes it possible to quickly put an object to be weighed, which is easily damaged and bounces, into the packaging device without damage.

Examples of objects to be weighed that are easily damaged and bounce include sugar-coated gummies. Sugar-coated gummies are oval and elastic, so they are easy to bounce, and if they hit vigorously, the sugar film will be damaged and the commercial value will be impaired.

Therefore, in the combination scale of this embodiment, the collecting funnel 9 is provided with a cushioning body 21 made of a cushioning material such as urethane rubber in a vertical posture extending vertically at the center thereof. The cushioning body 21 can cushion the object to be measured that slides down the collecting chute 8 and is vigorously thrown into the collecting funnel 9, and can prevent the object to be measured from being damaged.

The cushioning body 21 includes a plurality of vertical wall portions 21a extending radially outward from the central portion of the collecting funnel 9, in this example, four vertical wall portions 21a. The vertical wall portions 21a are formed at equal intervals along the circumferential direction of the collecting funnel 9, and extend in the vertical direction. As shown in FIG. 2, the vertical wall portion 21a of the cushioning body 21 has a substantially cross shape in a plan view.

Since the collecting funnel 9 is an inverted truncated cone-shaped cylinder, the outer end of each vertical wall portion 21a of the shock absorber 21 is closer to the inner peripheral surface of the collecting funnel 9 toward the lower end opening of the collecting funnel 9. To do.

The upper portion of the cushioning body 21 extending vertically is located at substantially the same position as the upper end opening of the collecting funnel 9. The lower portion of the cushioning body 21 penetrates the lower end opening of the collecting funnel 9 and extends to the inside of the collecting hopper 10. Therefore, the cushioning body 21 divides the internal space of the collective hopper 10 into four by four vertical wall portions 21a having a substantially cross shape in a plan view.

As shown in FIG. 7, the cushioning body 21 has four cushioning plates 23 made of urethane rubber having a thickness of about 2 mm on the four peripheral surfaces of the vertical support shaft 22 made of square shafts, and the central portion in the width direction thereof. It is configured by being concavely curved outward and connected by screws via a holding plate 24. By abutting and polymerizing the adjacent free end portions of the cushioning plates 23 that are concavely curved outward, the vertically wall portions 21a of the two layers are formed to extend in all directions.

In this way, the cushioning body 21 is connected to the outer periphery of the vertical support shaft 22 by bending a plurality of flexible and deformable cushioning plates 23, and the adjacent free ends of the respective cushioning plates 23 are abutted and polymerized. Since the vertical wall portion 21a is formed, the cushioning body 21 having the plurality of vertical wall portions 21a can be manufactured at low cost.

As shown in FIG. 1, the vertical support shaft 22 is connected and supported on the lower surface of the central portion of the center base 2 via the connecting screw shaft 25 and the support bracket 26, and is supported by the nut 25a of the connecting screw shaft 25. The height of the buffer 21 can be adjusted.

Two types of baffle plates 27 and 28 having different specifications are radially arranged on the inner peripheral surface of the collecting funnel 9.

As shown in FIGS. 8A and 8B, these baffle plates 27 and 28 are formed by arranging two thin stainless steel plates facing each other with a small interval (several mm) and welding them along the upper end side. It has a hollow double-walled structure that is joined, and is abutted and supported by screws on the outer peripheral edge of the collecting funnel 9 via connecting plates 27a and 28a that are welded and connected to the outer end thereof.

The upper end sides of the baffle plates 27 and 28 are butted and welded so that their vertical cross-sectional shapes are chevron in order to prevent damage to the objects to be weighed. Further, by opening the lower end sides of the baffle plates 27 and 28 downward, the side surface is allowed to be slightly bent and deformed, and the object to be measured that hits the side surface can be received as a buffer. ..

As shown in FIGS. 4 and 5, the baffle plate 27 of one specification is arranged to face each vertical wall portion 21a of the cushioning body 21. By inserting the outer end portion of the vertical wall portion 21a of the buffer 21 into the inner end portion of the baffle plate 27, that is, the extension portion 27b connected to the radially inner end portion of the collecting funnel 9. , The lateral vibration deformation of the vertical wall portion 21a in the circumferential direction is regulated.

As shown in FIG. 6, the baffle plate 28 of the other specification is arranged to face the intermediate portion of the adjacent vertical wall portion 21a in the cushioning body 21. The inner end portion of the baffle plate 28, that is, the radially inner end portion of the collecting funnel 9, is in contact with the outer surface of the central portion of the cushioning body 21. The inner end portion of the baffle plate 28 receives and supports the lower corresponding portion of the vertical support shaft 22 in the cushioning body 21 from all sides. As a result, the lateral vibration of the entire cushioning body 21 suspended and supported by the center substrate 2 can be prevented, and the cushioning body 21 can be positioned and held at the center of the collecting funnel 9.

As shown in FIG. 2, these baffle plates 27 and 28 divide the space on the outer peripheral side of the collective funnel 9 into which the object to be measured flows down into eight equal parts in the circumferential direction of the collective funnel 9. The lower end of the collective chute 8 faces each of the starting ends of the space in which the eight objects to be measured flow down, which are formed between the adjacent baffle plates 27 and 28.

In this example in which 24 measuring units are provided, one collective chute 8 guides the object to be weighed from the adjacent three measuring hoppers 7 down.

In the combination scale having the above configuration, the objects to be weighed w discharged from the plurality of weighing hoppers 7 selected to be within a predetermined weight range by the combination calculation are sent to the collecting funnel 9 via the corresponding collecting chute 8. , Guided to any of the eight flow-down spaces of the objects to be weighed, partitioned by baffle plates 27, 28.

The object to be weighed w flowing down the flow-down space of one object to be weighed is restricted from moving in the lateral direction, that is, in the circumferential direction of the collecting funnel 9 by the adjacent baffle plates 27 and 28, and the adjacent objects to be measured It flows down without jumping into the flow-down space. The object to be weighed w that flows down vigorously is received by the cushioning body 21 in a cushioning manner, and then is dropped and supplied to the collecting hopper 10 through the lower end opening of the collecting funnel 9.

At this time, the object to be measured w thrown into the collecting hopper 10 bounces or moves in the circumferential direction by the vertical wall portion 21a having a substantially cross shape in a plan view of the cushioning body 21 extending to the inside of the collecting hopper 10. This is suppressed in a buffering manner, and the object to be measured w becomes stable in the collecting hopper 10 in a short time.

As described above, according to the present embodiment, the object to be measured w thrown into the collective funnel 9 from the collective funnel 8 is received as a buffer by the buffer 21 arranged at the center of the collective funnel 9 to receive an impact. Since it is softened, it is possible to prevent the object to be weighed w from being damaged. Further, the vertical wall portion 21a of the buffer body 21 and the baffle plates 27 and 28 provided on the inner peripheral surface of the collective funnel 9 allow the space on the outer peripheral side where the object to be measured w of the collective funnel 9 flows down in the circumferential direction. It can be divided into eight along the line, suppresses bouncing or moving in the circumferential direction, and can be smoothly guided down to the lower collective hopper 10.

Further, the object to be measured w thrown into the collecting hopper 10 can be moved in the collecting hopper 10 by the four vertical wall portions 21a having a substantially cross-shaped plan view of the cushioning body 21 extending into the collecting hopper 10. It is regulated and promptly and stably contained.

In this way, the object to be weighed w can be smoothly put into the collecting hopper 10, and the movement of the object to be measured w in the collecting hopper 10 can be regulated and quickly stabilized.

As a result, the time interval for charging the object to be measured w from the collecting hopper 10 into the packaging device can be shortened, and high-speed weighing and packaging processing becomes possible.

Further, according to the present embodiment, the cushioning body 21 is connected and supported by the center base 2 via the connecting screw shaft 25 and the support bracket 26, while the baffle plates 27 and 28 have the connecting plates 27a and 28a. Since it is abutted and supported on the outer peripheral edge of the collecting funnel 9 via the structure, it is relatively easy to attach and detach. Therefore, in the case of an object to be weighed that is easily damaged and easily bounces, a buffer 21 and baffle plates 27 and 28 are attached to perform weighing as in the above embodiment, and a normal object to be weighed that is not easily damaged and is not easily bounced. In the case of, the buffer body 21 and the baffle plates 27 and 28 can be removed for weighing.

The larger the cushioning body 21 is extended into the collecting hopper 10, the higher the function of stabilizing the object to be measured w, but on the other hand, the substantially accommodating volume of the object to be measured w in the collecting hopper 10 becomes smaller. Therefore, the object to be weighed w is likely to be clogged. Therefore, it is preferable to adjust the height of the cushioning body 21 according to the amount of storage in the collecting hopper 10 and the size of the object to be measured.
