Description

Name of production: Combination weight

Technical field

The present invention relates to a combination weight carrying a metered workpiece using a screw conveyor.

Background

Patent literature 1 describes a combination weight.

This combination weight is provided with a detecting means for detecting an abnormality in the flow of a measured item at a boundary between a spreading agent, e.g. a tapered rotation table, and a means of transport, e.g. a auger. A control means controls respectively. the spreading means and the transporting means based on the abnormality detection in the flow of the measured item. When the spreading agent e.g. is a tapered rotation table, such as a combination weight, the rotation speed and direction of rotation of the rotation table change and act to transport the measured workpiece on the edge portion of the spreading means to the neighboring means of transport. When operated in this way it is possible to automatically distribute even a very sticky meter

DK 2017 00068 Y3 topic that could otherwise only be conventionally distributed by people.

Patent Literature

Patent Literature 1: JP 2011-209156 A

Summary of the Production

The measured item may become suspended between the neighboring augers depending on the condition of the measured item. When the measured item e.g. having an elongated shape, the longitudinal portions of the measured article may be trapped and hang between the adjacent augers. Furthermore, if the measured item is meat, there are situations where a plurality of measured item is not completely separated and is connected by elongated muscle fibers or the like. In that case, such muscles are captured e.g. between the neighboring augers with the result that the measured item may become stuck.

[0005]

As described in the above literature, a method of changing the direction of rotation of a tapered distribution table is taken into account in that case to eliminate the retention.

DK 2017 00068 Y3 [0006]

However, when the feed auger is used, depending on the combination of the distribution table rotation direction and the feed auger rotation direction, it has been found, even if the restraint can be lifted, that there is a problem that the feed quantity cannot be adequately controlled from the feed auger to the element disposed at the posterior stage of the auger.

[0007]

Specifically, (1) the distribution table rotates clockwise from substantially an upper side in a vertical direction, and (2) when a transport start side is viewed from a transport end side of the measured workpiece, a screw unit is rotated clockwise by the feed auger and the feed auger itself rotates. counter-clockwise. In the aforementioned case, as the feed auger becomes a resistor to the metered item, the metered item is transported according to the transport function of the feed auger.

That is, with such a combination of rotational directions, it is easy to control the feed rate from the feed auger.

[0008]

However, in order to eliminate the measured item being stuck between the feed augers, the feed auger functions in the same manner as described above, and when the distribution table rotates counterclockwise from substantially the upper side in a vertical direction,

DK 2017 00068 Y3 it is difficult for the auger to turn into resistance for the measured item. In that case, the measured item is not transported in connection with the transport function of the feed auger, but it moves along a trough by virtue of the measured weight's own weight. That is, in such a case, although it is possible to remove the measured item which is stuck between the feed augers, it is difficult to control the feed quantity from the feed auger.

[0009]

Therefore, the present disclosure provides a combination weight where it is possible to easily control the amount of feed to prevent the metered item from hanging between the adjacent feed augers, even when coupled from a condition where the distribution table and feed auger rotate in opposite directions of rotation. a state of rotation in the same direction of rotation by controlling the rotation drive of the distribution table to make the expected supply quantities in the respective states different from each other.

The solution to the problem [0010]

A first aspect of the present disclosure is summarized as combination weight with: a distribution table arranged to distribute a metered item to be fed

DK 2017 00068 Y3 from the outside using a rotary drive; a plurality of containers disposed around the distribution table; a gutter extending in a direction from a center of rotation of the distribution table toward the containers; a screw unit disposed in the gutter including a spiral member adapted to transport the measured workpiece supplied to the interior of the gutter by means of the distribution table to the container by means of the rotary drive; and a control unit adapted to control the rotation drive of the distribution table and the screw unit, the screw unit being adapted to be rotated in a first direction of rotation when a transport start side is viewed from a conveyor end side of the measured workpiece in the gutter; when the transport start side is viewed from the transport end side of the measured workpiece in the gutter, the control unit is adapted to perform an operating mode for rotating the screw unit about the rotary center of the screw unit in a second direction of rotation opposite to the first direction of rotation, and when a lower side is viewed from a substantially upper side in the direction of rotation. a vertical direction of the distribution table, the controller is arranged to intermittently couple a first rotation operation mode for rotating the distribution table in the first rotation direction and a second rotation operation mode for rotating the distribution table in the second rotation direction relative to the distribution center rotation center; and an expected supply amount of the measured item from the distribution table to the gutter in the first

GB 2017 00068 Y3 rotation operation mode is greater than an expected supply amount of the measured item from the distribution table to the gutter in the second rotation operation mode.

[0011]

Another aspect of the present disclosure is further summarized as a combination weight with: a distribution table distributing a metered item supplied from the outside by means of a rotary drive; a plurality of containers disposed around the distribution table; a gutter extending in a direction from the center of rotation of the distribution table toward the containers; a screw unit with a spiral member disposed in the gutter and transporting the measured workpiece supplied to the gutter by means of the distribution table to the container by means of the rotary drive; and a control unit controlling the rotation drive of the distribution table and screw assembly. The control unit controls the rotation drive in the distribution table and screw unit on the basis of the amount of transport of the measured workpiece to each of the plurality of containers.

Advantageous effects of production

In the combination weight of the present disclosure, it is to prevent the metered object from hanging between the neighboring augers, even by

Coupling from a state in which the distribution table and feed auger rotate in opposite rotational directions to a state of rotation in the same rotational direction make the expected supply quantities in the respective states different from each other by controlling the distribution table rotary drive. Thus, it is possible to easily manage the supply amount.

Description of Embodiments

Next, embodiments are described in detail with reference to the drawings, where appropriate. However, an unnecessarily detailed description may be omitted. For example, may be cases where detailed descriptions of well-known conditions or repeated descriptions of substantially the same embodiment are omitted. This is to avoid unnecessary redundancy of the following description and to facilitate understanding of the person skilled in the art.

[0015]

It should be noted that the inventors of the present invention provide the accompanying drawings and the following description to enable the person skilled in the art to

DK 2017 00068 Y3 sufficiently understand the present disclosure intended to limit the subject matter of the claims.

(Embodiment)

Next, the present embodiment is described with reference to FIG. 1 to 10.

[0017]

Next, a combination weight 1 according to the present embodiment is described with reference to the drawings.

[0018]

FIG. 1 is a schematic perspective view of the combination weight 1 of this embodiment.

[0019]

The combination weight 1 shown in FIG. 1 includes a distribution table 10, a transport unit 20, a screw unit 30, a pool container 40, a measuring container 50, a booster container 60, a collection discharge slider 70 and a guide block 80.

[0020]

Next, the operating weight of the combination weight 1 is first described.

[0021]

To make the description easier when the direction of rotation of the distribution table is described in the following description, the direction is defined as a direction of rotation when a axis of rotation C (see Fig. 1) extending in a

The upward downward direction is seen from essentially the upper side in the vertical direction. Further, when a direction of rotation of the screw unit 30 is described, the direction is determined as a direction of rotation when a transport start side is viewed from a transport end side of the measured workpiece in the screw unit 30.

That is, the direction of rotation of the screw unit 30 is determined as a direction of rotation based on a direction from the outer periphery of the combination weight 1 toward the center of rotation of the distribution table 10.

[0022]

First, the metered item is carried up to the combination weight 1 by means of a transverse feed device (not shown) disposed above the combination weight 1. Here, the metered item is a soft and sticky food such as chicken.

However, the measured item is not limited to this, and any kind of food can be used as long as it is difficult to transport by ordinary vibration transport.

[0023]

The metered workpiece transported by the transverse feed device is fed to the substantially central portion of the distribution table 10. The distribution table 10 is rotated about the axis of rotation C. Then, the distribution table 10 carries the metered workpiece fed from above to the outside in a radial direction, while the measured item spreads in the circumferential direction. The measured item distributed and

2017 201768 Y3 is transported by the distribution table 10, deduced from the outer peripheral edge of the distribution table 10.

[0024]

Here, the distribution table 10 switches intermittently between operation of rotating the measured workpiece clockwise (a first direction of rotation in the present embodiment) (hereafter referred to as a first rotation operating mode) and operation of turning the measured workpiece counterclockwise (a second direction of rotation in the present embodiment) (hereinafter referred to as another rotary operation mode) to remove the measured workpiece stuck between the adjacent screw units 30, in other words, the workpiece which hangs because it is caught by the guide block 80. As a result, it is exposed the measured subject for forces in different directions, and consequently it moves in different directions. In this action, it is possible to prevent the phenomenon where the measured object is suspended between the neighboring screw units 30.

[0025]

The measured workpiece discharged from the distribution table 10 is fed to a plurality of transport units 20 arranged in an annular shape below the distribution table 10. The plurality of transport units 20 extend radially from the rotation center O of the distribution table 10 (see Fig. 4). In other words, the plurality of transport units 20 extends

DK 2017 00068 Y3 radially from the combination center 1 center. Here, the guide block 80 is disposed between the neighboring transport units 20. By means of the guide block 80, the measured workpiece is prevented from falling between the transport units 20. Each transport unit 20 transports the measured workpiece supplied from the distribution table 10 to the pool containers 40 which are arranged. about the distribution table 10 one by one corresponding to each transport unit 20. Specifically, this means that the measured workpiece in each transport unit 20 is conveyed through a trough 21 by means of the rotary drive of the screw unit arranged in the gutter 21. Each transport unit 20 delivers the transported measured workpiece to the pool container 40 disposed below the outer end portion of the transport unit 20 (below the outer end portion of the gutter

21), thereby providing the measured item to the pool container 40.

[0026]

Pool container 40 temporarily holds the metered workpiece supplied from the transport unit 20. Subsequently, the metered workpiece held is supplied to corresponding measuring containers 50 which are placed one by one below the respective pool containers

40. In each measuring container 50, the weight of the measured item is measured by a measuring mechanism (not shown). The measured item discharged from the measuring container 50 is stored in corresponding booster containers 60, which are arranged one by one below each.

GB 2017 00068 Y3 measuring container 50 and held temporarily.

[0027]

A control unit (not shown) of combination weight 1 obtains the combination of containers corresponding to or closest to a target weight among the combinations of weights in a permissible range, by calculating on the basis of the weight of the measured item in the measuring container 50 and the booster container 60. The metered blank in the container contained in the combination obtained by calculating the controller is discharged to the collection discharge slider 70. The metered blank discharged to a collection discharge slider 70 is fed to a downstream process (not shown).

(1; Description of each component element of the combination weight 1)

Next, the distribution table 10, the transport unit 20, the pool container 40, the measuring container 50 and the booster container 60 are described in the combination weights 1 with reference to the drawings.

[0029]

FIG. 2 is a schematic perspective view of the distribution table 10 and the transport unit 20 of the combination weight 1 according to FIG. 1. FIG. 2 shows a state in which the guide block is released.

[0030]

DK 2017 00068 Y3

FIG. 3 is a partial cross-sectional view of the distribution table of the combination weight of FIG. 1 and the transport unit 20 of the combination weight 1 viewed from the side. In FIG. 3, the front of a recessed groove portion of the gutter 21 of the transport unit 20 is not shown. The holder of the screw unit 30 of the transport unit 20 is shown in a cross-sectional view.

[0031]

FIG. 4 is a schematic plan view of the combination weight of FIG. 1 from above. FIG. 4 shows a state in which the distribution table 10 is released. Only the outside edge of the distribution table 10 is shown by a dotted line.

[0032]

The distribution table 10 is an element distributing the measured item supplied from a transverse feed device (not shown) disposed above the combination weight 1.

The distribution table 10 further feeds the measured workpiece to the transport unit 20.

[0033]

Furthermore, the distribution table 10 is an element having a substantially circular shape in a plane view.

The distribution table 10 has a tapered portion 11 located at the central portion and a peripheral portion 12 disposed at the peripheral edge of the tapered portion 11 (see Fig. 2). Both the tapered portion 11 and the peripheral portion 12 incline so that the peripheral edge side of the distribution table 10 becomes lower (see FIG.

DK 2017 00068 Y3

3). The slope of the conical part 11 is designed to be steeper than the slope of the peripheral part (see Fig. 3).

[0034]

The distribution table 10 is supported by a drive shaft (see FIG.

3) located below the distribution table 10. The drive shaft supporting the distribution table 10 is connected to a distribution table motor 101. By operating the distribution table motor 101 by means of the control unit 102, the distribution table 10 is rotated about the axis of rotation.

C extending vertically.

[0035]

Details of the method for controlling the rotation drive of the distribution table 10 by means of the control unit

102 will be described later.

[0036]

When the metered workpiece is fed from the transverse feed device (not shown) positioned above the combination weight 1 to near the central portion of the distribution table 10 rotatably driven by the distribution table motor, the rotation drive of the distribution table 10 is controlled from the control unit.

102, and the metered article supplied is radially transported outward while distributed in the circumferential direction by centrifugal force. The measured item distributed and transported by the distribution table 10 is discharged from the outer peripheral edge of the distribution table 10 and falls into the

GB 2017 00068 Y3 gutter 21 (see Fig. 2) of one of the transport units 20.

[0037]

Transport unit 20 is an element which carries the measured item supplied from the distribution table 10.

The combination weight 1 in the present embodiment has 14 transport units 20. However, the number of transport units 20 is an example and not limited thereto. The combination weight 1 can e.g. be arranged to have eighteen transport units or to have twenty-four transport units 20.

[0038]

The plurality of transport units 20 are positioned below the distribution table 10 to surround the distribution table 10 (see FIG.

2). The plurality of transport units 20 extend radially from the periphery of the distribution table 10 to the pool container 40 disposed about the distribution table 10 in a plan view (see Fig. 4).

[0039]

More specifically, the plurality of transport units extend radially from one compartment (see Fig. 4) below the distribution table toward a pool container 40 disposed around the distribution table 10. Under each pool container 40, each weight container 50 corresponding to the pool container 40 is provided (see FIG. 1). That is, the transport unit extends radially from the periphery of the distribution table 10 to the weight container 50 disposed around the distribution table 10.

DK 2017 00068 Y3

The transport unit 20 transports the measured workpiece distributed by the distribution table 10 to the weight container 50 (in the transport direction D shown in Fig. 3).

[0040]

Each transport unit 20 has mainly a trough 21 and a screw unit 30 (see Fig. 2). The screw unit 30 is disposed within the gutter 21.

[0041]

The gutter 21 extends from the space below the distribution table toward the pool container 40 corresponding to the gutter 21 (see Fig. 3 and

4). Each trough 21 extends in a radial direction with respect to the center of rotation of the distribution table 10 in a plan view (see Fig. 4). Each of the troughs 21 of the plurality of transport units extends radially from the distribution table 10 as a whole (see Fig. 4).

[0042]

Each trough 21 is separated from the interior space of frame 90 by an upstream side wall portion 91 (see Fig. 3). The frame 90 is positioned below the distribution table 10 to support the distribution table 10. An opening section 1001 into which the screw unit is inserted is further provided in the frame 90, and at least one rotary drive unit 1002 described later and which transmits the driving force to the screw unit 30 is stored in the interior space of the opening section 1001 (see Fig. 3).

The rotation drive unit 1002 is connected to a motor that is

DK 2017 00068 Y3 provided in the main body of the device and rotates about the axis of rotation D shown in FIG. 3 in connection with the operation of the engine.

[0043]

Each trough 21 has a recessed groove portion 22 extending from the upstream side wall portion 91 and having an inner surface.

22a, which curves in a semicircular shape (see Fig. 2). The recessed groove portion 22 is formed in a groove shape recessed downwardly by an inner surface 22a which curves in a semi-circular shape. In a plan view, the recessed groove portions 22 of each gutter 21 extend from the upstream side wall portion 91 to the pool container 40 in a radially outward direction relative to the rotationally oscillating space 0 of the distribution table 10. The recessed groove portion 22 inclines such that its outer edge side becomes lower, in other words, the side of the pool container 40 becomes lower than the side of the distribution table (see Fig. 3).

[0044]

The measured workpiece discharged from the outer peripheral edge of the distribution table 10 is fed to the gutter 21.

[0045]

The metered workpiece supplied to the gutter 21 is conveyed to the pool container 40 by means of the rotary drive of the screw unit disposed in the gutter 21. More specifically, the screw unit 30 transports the metered workpiece to

GB 2017 00068 Y3 pool container 40 by turning the screw element 31 disposed in the gutter 21.

[0046]

Each screw unit 30 is arranged for each trough 21 (see FIG.

4). The measured workpiece falling on the gutter 21 is conveyed in the gutter 21 by means of the rotary drive of the screw unit 30. The design of the screw unit 30 is described later.

[0047]

The rotation drive of the screw unit 30 is controlled by the control unit

102.

[0048]

Each pool container 40 is provided below the outer edge side of each channel 21. Pool container 40 stores the metered item conveyed by the transport unit 20 and temporarily holds the metered item. Pool container 40 supplies the metered item held temporarily to the weight container 50 provided under the pool container

40, by opening an opening and closing port (not shown) provided at the bottom of the pool container 40.

[0049]

The weight container 50 is an example of a weighting agent.

The weight container 50 is disposed around the distribution table 10.

Specifically, each weight container 50 is provided under each pool container 40. In other words, each weight container 50 is

Provided below the outer edge of the gutter 21 of each transport unit 20. The weight container 50 stores the metered item supplied from the pool container 40 and temporarily holds the metered item. In addition, the weight container opens an opening and closing port (not shown) provided at the bottom of the weight container 50 to supply the metered workpiece held temporarily to the booster container 60 provided under the weight container 50.

[0050]

Each weight container 50 has a weight (not shown) that measures the weight of the measured item in the weight container 50. The weight is

eg. a load cell. The weight result of the weight is transferred to a control unit (not shown) of the combination weight 1.

[0051]

Each booster container 60 is provided under each weight container 50. The booster holder 60 is arranged to store and temporarily hold the metered item supplied from the weight container 50. The booster container 60 opens the opening and closing port (not shown) provided in the lower portion of the booster container 60, to supply the metered item held temporarily to the collection discharge slit 70 provided under the booster container 60. When the booster container 60 receives the supply of the metered item from the weight container 50 if the opening and closing port (not shown), that is provided

In the lower part of the booster container 60, opened, it is possible to supply the metered item to the collection discharge slit without first holding the metered item by the booster container 60.

(2-1; Specific Design of Screw Unit 30)

Next, the design of screw unit 30 is described with reference to the drawings.

[0053]

FIG. 5 is a schematic perspective view showing a structure of the screw unit 30 in the present embodiment.

[0054]

FIG. 6 is a schematic view showing the structure of the screw unit 30 in the present embodiment.

[0055]

FIG. 6 is a view showing an outside diameter member 32 intersected on a predetermined plane and is shown to show a relationship between a grooved cam provided on an inside diameter member 33 and the outside The diameter element 32 disposed about the grooved comb can be understood.

[0056]

FIG. 7 is also a view showing the frame 90 which

The 2017 screw unit 30 is attached to and an opening section 1001, the rotary drive unit 1002 and the protruding portion 1003 provided in the frame 90.

[0057]

As shown in FIG. 3, the screw unit 30 is mounted in the opening section 1001 formed in the frame 90 by a user.

[0058]

Here, the aperture section 1001 has a hole-like structure formed in the frame 90. The rotary drive unit 1002 connected to a motor is disposed within the aperture section.

1,001th

[0059]

The rotation drive unit 1002 is connected to a motor (not shown) and rotates about the axis of rotation D shown in FIG. 3, by operating the engine. The axis of rotation D is a axis of rotation which is predetermined to be substantially the same as the direction of insertion to which the screw unit 30 is inserted into the aperture section 1001.

[0060]

Furthermore, a protruding portion 1003 is formed at the end portion of the rotary drive unit 1002 (see Fig. 7). The protruding portion 1003 rotates about the axis of rotation D in connection with the rotation of the rotary drive unit 1002. The protruding portion 1003 is provided with a grooved cam which is

Furthermore, the projecting member 1003 may move as it slides on the grooved cam.

[0061]

As shown in FIG. 5, the screw unit 30 (screw section) comprises mainly a screw element 31, an outside diameter element 32 and an inside diameter element 33.

[0062]

As shown in FIG. 3, the screw member 31 includes at least one linear member 31a having a helical shape. However, the screw member may further include a linear member 31b. In the present embodiment, it is assumed that the screw member 31 includes the linear member 31a and linear member 31b as helical members as shown in FIG. 5th

[0063]

As shown in FIG. 5, the linear member 31a and the linear member 31b are elements twisted clockwise around the center of rotation of the screw member (a first direction of rotation in the present embodiment). In other words, the linear member 31a and the linear member 31b are left-hand screw members.

[0064]

Here, the linear element 31b is an element extending in the same direction as the linear element 31a and not physically

DK 2017 00068 Y3 intersects the linear element 31a. The cross sections of linear member 31a and linear member 31b may consist of a perfect circle. Further, the linear elements may have a polygonal cross-section such as a box-shaped shape. In the case of a polygonal shape, because there is a so-called corner in the linear element, the transport capacity of the measured object is improved.

[0065]

The screw element 31 is connected to the inner diameter element 33 and the screw element 31 also rotates in connection with the rotation of the inner diameter element 33. That is, when the rotary drive unit 1002 shown in FIG. 6, the inside diameter element 33 rotates in the same direction as the rotation of the rotary drive unit 1002. Furthermore, as the inner diameter element 33 rotates, the screw element 31 connected to the inner diameter element 33 rotates. The measured workpiece is transported within the gutter and transported to the pool container 40 as the screw member 31 rotates.

[0066]

Specifically, the screw member 31 also rotates counterclockwise as the rotation drive unit 1002 rotates counterclockwise. Here, the linear element 31a and the linear element 31b are high-ranking elements, in other words left-standing elements. When

GB 2017 00068 Y3 screw element 31 rotates counterclockwise, the measured workpiece is therefore transported from the transport start end to the transport end end, shown in fig. 5th

[0067]

The outside diameter member 32 is a cylindrical member connected to the screw member 31. Since the inside diameter member 33 is disposed within the outside diameter member 32, the outside diameter member 32 also has a donut shape in cross section. The outer diameter element 32 is further arranged around the inner diameter element 33 via bearings or the like and is adapted to have little influence on the rotational process in the inner diameter element 33.

That is, even as the inside diameter element 33 rotates, the outside diameter element 32 is arranged not to rotate upon receiving the rotational force thereof.

[0068]

The inner diameter element 33 is a cylindrical element which is connected to the screw element 31. Since the rotary drive unit 1002 and the projecting part 1003 are inserted into the inner diameter element 33, the cross section thereof has a donut shape. The inner diameter element 33 is arranged in a space formed within the outer diameter element 32.

The inner diameter element 33 is further mounted on it

GB 2017 00068 Y3 protruding portion 1003 and has a grooved cam upon which the protruding portion 1003 slides from the mounted condition.

This grooved comb is a grooved comb in which a groove is formed in a spiral shape. Specifically, starting from a portion of an inner diameter member 33 mounted on the protruding portion 1003, the grooved cam has a groove formed in a helical shape from the starting point. As the protruding portion 1003 moves as it slides relative to the grooved cam, the inner diameter member 33 is inserted into the main body.

[0069]

To make the description easier when the screw unit 30 is attached to the main body, a part initially mounted on the protruding part 1003 is referred to as a first grooved cam part. A portion comprising the protruding portion

1003 moves while sliding from the state in which the protruding part 1003 is mounted on the first grooved cam part is referred to as a second grooved cam part.

[0070]

The first grooved cam part and the second grooved cam part are designed to be physically continuous with each other. That is, after the protruding portion 1003 slides and moves on the first grooved cam portion, the second grooved cam portion may continuously slide and move on the second grooved cam portion as it is. To move the protruding portion 1003 from it

However, from a second grooved cam part to the second grooved cam part to the first grooved cam part, it is necessary for a user to change the direction of the force applied to the screw unit 30.

[0071]

More specifically, the coupling member between the first grooved cam member and the second grooved cam member is preferably discontinuous in the direction in which the protruding member 1003 slides and moves. Specifically, the first grooved cam member has a configuration in which the grooved cam member is formed in the same direction as The axis of rotation D. In contrast, the second grooved cam portion is a grooved cam formed in a helical shape with respect to the outer periphery of the inner diameter member 33.

[0072]

With such a design, the process when the protruding part 1003 is mounted in the first grooved cam part and the process when the protruding part 1003 is moved while sliding on the first grooved cam part and the second grooved cam part can be made different from one another. Furthermore, when the protruding portion 1003 is mounted in the first grooved cam portion, the user can apply a force in the same direction as the axis of rotation D. Therefore, even when it is difficult for him to see the fastening portion between the protruding portion 1003 and the first grooved portion, intuitively

GB 2017 00068 Y3 mount the screw unit 30 on the protruding part 1003.

[0073]

Furthermore, the designs of the first grooved cam part and the second grooved cam part are not limited to those described above, and any design can be used as long as the force applied to the screw unit 30 by the user is changed.

(2-2; About Method of Controlling the Distribution Table Using a Controller 102)

Next, a method of controlling the distribution table 10 by means of the controller 102 is described with reference to the drawings.

[0075]

Figures 8 and 9 are schematic views showing the movement of the measured item on the distribution table 10. To make the description easier, Figures 8 and 9 are shown as views showing a relationship between the distribution table 10 and the guide block 80, and descriptions of component elements other than the distribution table 10 and the guide block will not be provided. In an actual product, at least the screw unit 30 is disposed between the guide blocks 80 to transport the measured workpiece supplied from the distribution table 10.

[0076]

DK 2017 00068 Y3

Then, to make the description easier, a right side side face of guide block 80 as shown in Figures 8 and 9 is defined as a first side face seen from the transport end to the transport start end of the measured workpiece in screw unit 30. Conversely, a side face on the left side of the guide block 80 defined as another side surface.

[0077]

The control unit 102 controls the rotary drive of the distribution table 10 to prevent the metered object from hanging between the adjacent screw units 30. Specifically, the control unit 102 intermittently switches between a first rotary operating mode in which the distribution table 10 is rotated clockwise and a second rotary operating mode in which the distribution table 10 is operated. rotating counterclockwise.

[0078]

At this point, the control unit 102 controls the respective rotational operating modes of the distribution table 10, so that an expected amount of feed of the measured workpiece supplied from the distribution table 10 in the first rotary operating mode to the gutter 21 (i.e. the screw unit 30, the same applies hereafter), is accordingly greater than an expected supply amount of the measured workpiece supplied from the distribution table 10 to the screw unit 30 in the second rotary operation mode.

[0079]

DK 2017 00068 Y3

Here, the expected supply quantity is e.g. a value representing an amount of supply until the predetermined rotation mode is switched to another rotation mode. In the above embodiment, the expected amount of supply to the screw unit 30 is obtained by means of the distribution table 10, e.g. until the predetermined rotation mode is switched from the first rotation mode to the second rotation mode.

Furthermore, the expected supply amount is not limited to the above-described design and may be the expected quantity supplied from the distribution table 10 to the screw unit per unit. unit of time. In short, the expected supply amount in the present embodiment can be any as long as it is the expected supply amount from the distribution table 10 to the screw unit 30 based on the predetermined criteria.

[0080]

The expected amount of supply may be a value determined directly for the controller 102 by the user. In that case, the control unit 102 controls the rotation operation process of the distribution table 10 relative to the predicted amount of feed supply.

[0081]

Furthermore, the expected amount of supply is not a value determined for the controller 102, but may be a

DK 2017 00068 Y3 supply quantity which is experienced by the user from the parameters relating to the rotation drive of the distribution table 10, such as operating time, angular velocity and angular acceleration of the distribution table 10 used when the control unit 102 rotates the distribution table 10. When

eg. only the operating time among the parameters relating to the rotation drive of the distribution table 10 is adjusted, the user generally recognizes that the longer the operating time, the greater the expected supply quantity. In short, the expected supply amount in the first rotary operation mode may consequently be greater than the expected supply amount in the second rotational operation mode. In other words, the controller can

102 is controlled to achieve the above result based on the expected amount of supply determined by the user or device itself, or by determining the control parameter relating to the rotation drive via the user.

[0082]

Next, a method of the rotation drive is described by means of the controller 102.

[0083]

The controller 102 or the user can e.g. determine the operating time of the distribution table 10 in the first rotation operation mode to be longer than the operating time of the distribution table 10 in the second rotation operation mode to do the expected

GB 2017 00068 Y3 supply quantity in the first rotation mode is greater than the expected supply amount in the second rotation mode.

[0084]

The controller 102 or the user can e.g. determine the angular acceleration of the distribution table 10 in the first rotational operation mode to be higher than the angular acceleration of the distribution table in the second rotational operation mode to make the expected supply amount in the first rotational operation mode greater than the expected supply amount in the second rotational operation mode.

[0085]

The controller 102 or the user can e.g. determine the angular velocity of the distribution table 10 in the first rotary operation mode to be higher than the angular velocity of the distribution table in the second rotational operation mode to make the expected supply amount in the first rotational operation mode greater than the expected supply amount in the second rotational operation mode.

[0086]

The control unit 102 or the user may further be arranged to perform the control by changing two or more control parameters relating to the rotation drive of the distribution table 10.

[0087]

FIG. 10 is a diagram showing a relationship between

DK 2017 00068 Y3 distribution table 10 rotation drive and expected supply quantity.

[0088]

In FIG. 10 represents a vertical axis angular velocity of the distribution table 10. And a horizontal axis represents time. Therefore, the slope of the graph shown in FIG. 10 the angular acceleration of the distribution table 10. Here, the movement of the distribution table 10 is clockwise in the graph of FIG. 10 is shown as a positive value, and conversely, the movement of the distribution table 10 is counterclockwise shown as a negative value. That is, a region in which the vertical axis is positive in the graph shown in FIG. 10, represents a mode of operation in the first rotary mode of operation. Meanwhile, represents an area in which the vertical axis is negative in the graph shown in FIG. 10, a mode of operation in the second rotary mode of operation.

[0089]

When expressed in this way, the expected supply amount from the distribution table 10 to the screw unit 30 can be considered as an area of a shaded portion shown in FIG.

10 (a).

[0090]

Specifically, the expected amount of supply until the first rotary operating mode is coupled to the second rotational operating mode can be expressed as the area of the shaded

DK 2017 00068 Y3 part from time 0 to time ten, shown in fig. 10 (a). Furthermore, until the switching from the second rotational mode to the first rotational mode, the expected amount of supply can be expressed as the area of the shaded portion from time t1 to time t2, shown in FIG. 10 (a).

[0091]

At that point, the controller 102 or the user compares the two ranges and changes at least one of the operating time, angular velocity and angular acceleration, so that the area of the first rotary operating mode becomes smaller than the area of the second rotary operating mode.

[0092]

Somvistifig. 10 (b), a third rotation operation mode, where the angular velocity of the distribution table 10 becomes zero, may be included when switching from the first rotation operating mode to the second rotation operating mode. In that case, wear in the device can be prevented as it is possible to reduce the load on the rotary shaft of the distribution table 10.

(3; Summary)

The combination weight 1 according to the present embodiment includes a distribution table 10 which distributes a metered item supplied from the outside, a plurality of pool containers 40 disposed around the distribution table 10,

GB 2017 00068 Y3 a gutter 21 extending in the direction of the pool container 40 from a center of rotation 0 of the distribution table 10, a screw unit

30 disposed in the gutter 21 and includes a spiral member which transports the metered blank which is fed to the interior of the gutter (i.e., screw assembly 30) by means of the distribution table

10, to the pool container 40 by means of the rotation drive and a control unit 102 which controls the rotation drive of the distribution table 10 and the screw unit 30.

[0094]

The screw unit 30 is further rotated in the first direction of rotation (e.g. clockwise) when the transport start side is viewed from the transport end side of the measured workpiece.

[0095]

Furthermore, when the transport start side is viewed from the transport end side of the measured workpiece, the controller 102 performs an operating mode of rotating the screw units 30 about the center of rotation of the screw unit 30.

O in the second direction of rotation (e.g. counterclockwise) opposite the first direction of rotation. When the lower side is viewed from the upper side in the substantially vertical direction of the distribution table

10, (1) the controller 102 further switches the first rotary operating mode by rotating the distribution table 10 in the first rotational direction and (2) the second rotary operating mode by rotating the distribution table in the second one.

DK 2017 00068 Y3 direction of rotation with respect to the distribution center 10 of the distribution table 10.

[0096]

The expected supply amount from the distribution table 10 to the screw unit 30 in the first rotation operation mode is greater than the expected supply amount from the distribution table 10 to the screw unit 30 in the second rotation operation mode.

[0097]

In the present embodiment, the first direction of rotation is described as a clockwise direction. At the same time, the second direction of rotation is described as a counterclockwise direction which is a direction of rotation opposite to the first direction of rotation.

[0098]

As the distribution table 10 rotates clockwise, the metered workpiece is applied to the distribution table 10 here as shown in Figures 8 (a) and 8 (b). That is, the measured workpiece on the distribution table is supplied from the distribution table 10 in the direction of the first side surface of the guide block 80. As the screw unit 30 rotates counterclockwise as described above, the linear unit 31a and linear element 31b of the screw unit then become a resistance to the measured workpiece. This is because the linear member 31a and linear member 31b of the screw unit are formed as a left-hand screw as described above, and the screw unit itself is rotated counterclockwise. As a result

The metered workpiece is transported within the gutter 21 in connection with the rotary drive of the screw unit 30.

[0099]

Conversely, as measured in Figures 9 (a) and 9 (b), the metered workpiece is applied to the distribution table as the distribution table 10 rotates counterclockwise. That is, the measured item on the distribution table 10 is fed from the distribution table 10 in the direction of the second side surface of the guide block 80. Since the screw unit 30 rotates counterclockwise, as in the case where the distribution table 10 rotates clockwise, the linear element 31a and linear element 31b of the screw unit 30 does not at that time become a resistor to the measured workpiece. This is because the linear member 31a and linear member 31b of the screw unit 30 are formed as left-hand screws as described above, and the screw unit 30 itself is rotated counterclockwise. As a result, at least a portion of the measured workpiece does not lock with the rotary drive of the screw unit 30, but slides within the gutter 21 by virtue of its own weight and is supplied to the pool container 40.

[0100]

Depending on a relationship between the direction of rotation of the distribution table 10 and the direction of rotation of the screw unit 30 and the direction of rotation as described above, it is not possible to appropriately control the amount of supply from the screw unit 30 to the pool container 40 solely by controlling the rotation drive of the screw unit 30. That is, when the linear element 31a

Y 2017 and the linear element 31b of the screw unit 30 are left-hand screw mechanisms, if the distribution table 10 and the screw unit 30 are in different rotational directions, then it is easy to control the supply amount from the screw unit 30 to the pool container 40.

Conversely, if the distribution table 10 and the screw unit 30 are in the same direction of rotation, it is difficult to control the supply amount from the screw unit 30 to the pool container 40.

[0101]

Therefore, as described in the present embodiment, by controlling the expected supply amount from the distribution table 10 to the screw unit 30 in accordance with the direction of rotation of the distribution table 10, it is possible to easily control the supply quantity from the screw unit 30 to the pool container 40 while preventing retention of the measured item.

[0102]

The operation time of the first rotation operation mode is preferably set to be longer than the operation time of the second rotation operation mode.

[0103]

With such a design it is possible to increase the area of the shaded part, e.g. shown in FIG. 10 (a) or FIG. 10 (b)

As long as the control parameters other than the operating time are the same among the control parameters in the first rotation mode and the second rotation mode, the expected supply amount in the first rotation mode can therefore

For example, the 2017 20176868 Y3 is determined to be greater than the expected supply amount in the second rotary operation mode.

[0104]

Therefore, by controlling or changing the operating time in the first rotary operation mode and the second rotational operation mode without carrying out a complicated control, it is possible to easily control the supply amount from the screw unit 30 to the pool container 40 while preventing retention of the measured workpiece.

[0105]

The angular velocity of the distribution table in the first rotary operating mode is more preferably determined to be higher than the angular velocity of the second rotary operating mode.

[0106]

With such a design, e.g. possible to increase the area of the shaded portion, e.g. shown in FIG. 10 (a) or FIG. 10 (b). Therefore, as long as the control parameters other than angular velocity are the same among the control parameters of the first rotary operating mode and the second rotary operating mode, the expected supply amount in the first rotational operating mode can, for example, be determined to be greater than the expected supply amount in the second rotational operating mode.

[0107]

DK 2017 00068 Y3

Therefore, by controlling or changing the angular velocity in the first rotary operation mode and the second rotational operation mode without carrying out a complicated control, it is possible to easily control the supply amount from the screw unit 30 to the pool container 40, while preventing retention of the measured workpiece.

[0108]

The angular acceleration of the distribution table in the first rotation mode is preferably higher than the angular acceleration in the second rotation mode.

[0109]

With such a design it is possible to increase the area of the shaded part, e.g. shown in FIG. 10 (a) or FIG. 10 (b).

Therefore, as long as the control parameters other than angular acceleration are the same among the control parameters of the first rotary operating mode and the second rotational operating mode, the expected supply quantity in the first rotational operating mode can, for example, be determined to be greater than the expected supply quantity in the second rotational operating mode.

[0110]

By simply controlling or changing the angular acceleration in the first rotary operating mode and the second rotary operating mode without carrying out a complicated control, it is thus possible to easily control the supply amount from the screw unit 30 to

GB 2017 00068 Y3 pool container 40, while retaining the measured item is prevented.

[0111]

Controller 102 preferably has a third rotation mode for stopping the rotation of the distribution table 10 and executing the third rotation mode when coupling between the first rotation mode and the second rotation mode.

[0112]

With such a design, wear in the device can be prevented as it is possible to reduce the load on the rotary shaft of the distribution table 10.

[0113]

In the present embodiment, the function of rotating the screw unit 30 counterclockwise has also been described. However, when the distribution table 10 and the screw unit 30 are rotated counterclockwise, it is also possible, with the expectation of an increase in the amount of measured workpiece supplied from the screw unit 30 to the pool container 40, that the control unit 102 stops or reverses the rotation drive in the screw unit.

[0114]

In the present embodiment, the rotation drive of the distribution table 10 is interspersed between the first rotation mode and the second rotation mode.

DK 2017 00068 Y3

However, even if the intermittent coupling is performed since the expected amount of supply can be adjusted by means of such a screw unit 30, a more detailed control can be performed. It makes it easy to control the supply amount from the screw unit 30 to the pool container 40 in the device.

[0115]

As described above, the embodiment has been described as an example of the technique of the present disclosure. The accompanying drawings and the detailed description are provided for this purpose.

[0116]

Thus, some of the component elements described in the accompanying drawings and the detailed description may also include not only component elements which are essential to solving the problem, but also component elements which are not essential to solving the problems to illustrate the foregoing technique. . Although the non-essential components are described in the accompanying drawings and the detailed description, it is not immediately recognized that the non-essential component elements are essential.

[0117]

The shape of the distribution table 10 is e.g. not limited to the shape of the above embodiment, and the distribution table

10 having a uniform gradient may also be used. It will

DK 2017 00068 Y3 say that any form of distribution table 10 can be used.

[0118]

Furthermore, although the guide block 80 is arranged to be removable, a design in which the guide block 80 is designed integral with the gutter 21 is also an option.

[0119]

In addition, the inner surface 22a of the recessed groove portion may have an inclined configuration.

[0120]

In the above embodiment, the combination weight with booster container 60 has been described, but a device without booster container 60 is also an option.

[Modified Example]

Next, a modified example of combination weight 1 in the aforementioned embodiment is described, considering differences from combination weight 1 in the embodiment described above.

[0122]

In combination weight 1 of this modified example, the control unit 102 is arranged to control the rotation drive of the distribution table 10 and the screw unit 30, on the basis of the amount of transport of the measured workpiece to each of the plurality of containers (e.g. each of the pool containers 40, each of the

GB 2017 00068 Y3 weight containers 50, each of the booster containers 60 and the like).

[0123]

When it is determined that the weight of the measured item measured by each weight container 50 does not meet the desired condition, the controller 102 may e.g. be arranged to control the rotation drive of the distribution table 10 and the screw unit to live up to such a desired state.

[0124]

Furthermore, since the above described embodiment is intended to exemplify the technique of the present disclosure, various modifications, substitutions, additions, deletions and the like may be made within the scope or equivalent thereof of the utility model claims.
