Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket conveyor and a discharge mechanism in a bucket conveyor, and more particularly to a bucket conveyor and a discharge mechanism in a bucket conveyor in which a chain conveyor is vertically arranged.

[0002]

2. Description of the Related Art Generally, agricultural products, marine products, etc. are roughly sorted in each market, and some products are then sent to a processing plant. In a market or a processing plant, these items may be sorted within a fixed frame according to size, weight, or the like. In that case, for example, it is preferable that small scallop scallops or small marine products such as octopus are weighed one by one and automatically sorted into a fixed frame while being transported.

By the way, when this kind of product is conveyed by a vertically arranged bucket conveyor, the bucket has conventionally been provided with two support portions on both sides for loading and unloading openings of the product, and a pair of left and right of these is provided. The mounting shaft was inserted through the support portion, and it was mounted between the chains by two mounting shafts.

FIG. 13 shows an example of a conventional conveyor apparatus using a bucket conveyor that circulates horizontal and vertical conveyance by a pair of chains.

In this carrier device 1, gear units 4, 5, 6, 7 are supported in a rectangular frame 3 formed by an angle 2. Rotational force by a motor (not shown) is transmitted to a pulley 8 provided in the gear device 4 via a belt, and driving force is transmitted to the conveying means 9 via the gear device 4.

As shown in FIG. 14, the conveying means 9 comprises a pair of two-strand chains 10 and 11, and these two chains
A pair of shaft locking portions 12, 12 and 13, 13 are arranged on the strip chains 10, 11 at predetermined intervals. Plates 14 and 15 are arranged on the inner sides of the two-strand chains 10 and 11, respectively, adjacent to the chains.

On the other hand, the bucket 16 has an opening on one side and a substantially trapezoidal cross section, and has both ends of both side wall portions 16a and 16b arranged parallel to the two-strand chains 10 and 11 for shaft attachment. Bosses 17a, 17b, 17c, 17d are formed.

Bucket 16 having such a boss formed
13 and 14, the long shaft 18 is inserted into the bosses 17b and 17d on the front side with respect to the transport direction A indicated by an arrow in FIGS.
Both ends of the long shaft 18 are inserted into the two-strand chains 10 and 11 and locked to the shaft locking parts 12 and 13, respectively. On the other hand, the bosses 17a, 17 on the rear side with respect to the transport direction A
A short shaft 19 is inserted through c, and both ends of the short shaft 19 are locked to the plates 14 and 15.

As described above, the bucket 16 has two shafts 1.
8 and 19 are inserted and continuously set on the gantry 3 at predetermined intervals. A series of buckets 16 set on the gantry 3.
Thus, when the goods are conveyed, the goods are sequentially loaded into the bucket 16 in the horizontal state from the position above the gantry 3. Then, at the place where the items are accumulated, the plate 14,
By arranging the end portions 14a, 15a of the plate 15, the short axis 19 of the bucket 16 passing therethrough is fixed to the plates 14, 1,
5, the bucket 16 is rotated about the other long shaft 18 as a fulcrum to drop the item downward.

By the way, in such a conveyor device using a bucket conveyor, the bucket 1 which has become empty after the completion of the conveyance.
After that, 6 runs on the lower transfer path portion of the gantry 3 while being suspended by one long axis, and further moves upward in the vertical direction, and on the plates 14 and 15 by an appropriate means near the end of the upward movement. Minor axis 1
9 is reset.

Therefore, in the conventional bucket conveyor, the vertical movement of the bucket 16 is a suspension posture in which the opening is in the lateral direction, and articles cannot be loaded in the portion that moves in such a posture. Therefore, there is a limitation in the work space or the like where the bucket conveyor is used.

Further, in order to allow the goods to be put into the bucket 16 from the vertical transfer path portion, for example, the bucket is supported by one shaft at an intermediate position in the width direction, and the bucket is carelessly rotated. It is conceivable to use a bucket that is longer than the width direction in consideration of the stability of the center of gravity with respect to rotation, but in this case, there is a problem that the bucket becomes large. When the bucket becomes large, there is a problem that the function of discharging the item from the bucket also becomes large.

Further, in the above-mentioned transfer device, since the short shaft 19 slides on the plates 14 and 15, it is necessary to provide a lubricating means for this sliding portion, and the operating oil used by this lubricating means is in the bucket. If it adheres to, there is a problem that the commercial value of the conveyed product is impaired.

Further, in the carrying device 1, for example, articles such as scallop scallops or tarako cannot be sorted by weight during the carrying. When sorting by weight with this device, it is necessary to set a plurality of rows of bucket conveyors on the gantry 3 and sort the bucket conveyors before sorting the articles. Therefore, it is difficult to apply the apparatus as a sorting apparatus that weighs the articles one by one and automatically sorts the articles into a fixed frame while transporting.

In view of such a problem, the applicant of the present invention has first carried out the transportation of foods such as scallop scallops or cod roe without adhering lubricating oil or the like, and sorting the foods by weight into each class. Provided is a transfer device using a bucket conveyor that can be used. In this transfer device, the bucket has a substantially triangular cross section, and is supported by a pair of chains on both side wall parts thereof by a pivot so as to be rotatable, and in this suspended state, the front wall part and the rear wall part are inclined upward. A guide piece extending substantially vertically in the suspended state is attached to at least one of the both side wall portions in a certain shape, and the vertical guide member provided along the vertical transfer path portion of the bucket conveyor is A plurality of electromagnetic solenoids are provided in the stationary portion along the horizontal transfer path of the bucket conveyor at predetermined position intervals so that the guide pieces are brought into contact with each other, and the electromagnetic solenoids extend downwards. A coupling member is attached, and the engaging member selectively takes an engaging position and a non-engaging position by reciprocating motion of the operator by excitation and non-excitation of each of the electromagnetic solenoids, and Electromagnetic A bucket tilting member is provided at the stationary portion on the most downstream side of the horizontal transfer path portion provided with a noid, and the bucket tilting member is always in an engagement position with the bucket, and the bucket tilting member is provided at the vertical transfer path portion. One item supplied to the bucket is weighed by a weigher, and the electromagnetic solenoid corresponding to the weighed result is excited depending on how large the weighing result of the weigher is. By causing the engagement member to take the engagement position, the bucket stores the weighed item, and the guide piece is moved by the corresponding electromagnetic solenoid while being transferred through the horizontal transfer path portion. Engage with the engaging member to rotate the bucket around the support shaft to drop the articles contained within the range stored therein, to discharge the articles, and store the articles outside the range. The ba Tsu TMG, dropping the goods in the said range that accommodates when is rotated around said support shaft by said bucket tilting member provided on the most downstream side, is obtained so as to be discharged.

According to this carrying device, it is possible to load articles even from the vertical transfer path of the bucket, and
The bucket does not become large, and the bucket resetting means is not necessary.

However, since the bucket tilting member is fixedly installed on the stationary portion in the above-described transporting device, when the bucket comes into contact with the bucket tilting member, the impact force of the bucket greatly acts on the bucket. For example, a bucket that has just dropped an item in the vicinity of the bucket tilting member has a large shake, and when such an unstable bucket comes into contact with the bucket tilting member, not only is the collision noise loud, but in some cases There is a problem that the support portion of the guide piece is damaged.

[0018]

SUMMARY OF THE INVENTION In view of the above problems, the present invention absorbs the thrusting force when the bucket comes into contact with the bucket tilting member, so that the bucket can be stably operated without damaging the bucket. An object of the present invention is to provide a bucket and a discharging mechanism in a bucket conveyor that can be rotated.

[0019]

In order to solve the above problems, the bucket has a substantially triangular cross section, and the bucket is rotatably supported by a pair of chains on both side wall portions thereof by a support shaft. And the shape of the rear wall is inclined upward,
Further, a guide piece extending substantially vertically in the suspended state is attached to at least one of the both side wall portions, and the guide piece is brought into contact with a vertical guide member provided along a vertical transfer path portion of the bucket conveyor. In addition, a plurality of electromagnetic solenoids are provided in the stationary portion along the horizontal transfer path portion of the bucket conveyor at predetermined position intervals, and an engaging member extending downward is attached to an actuator of each electromagnetic solenoid. The engaging member selectively takes an engagement position and a non-engagement position by reciprocating motion of the actuator by excitation and non-excitation of each electromagnetic solenoid, and the plurality of electromagnetic solenoids are provided. A bucket tilting member is provided in the stationary portion at the most downstream side of the horizontal transfer path portion, and the bucket tilting member is always in the engagement position with the bucket, and the bucket tilting member is provided in the vertical transfer path portion. One item to be supplied to the weigher is weighed by a weigher, and the electromagnetic solenoid corresponding to the weigher is excited depending on the magnitude range of the weighing result of the weigher. By setting the engaging position of the engaging member, the bucket accommodates the item weighed, and the guide piece is moved by the engagement of the corresponding electromagnetic solenoid while being transferred through the horizontal transfer path. Engage with a mating member to rotate the bucket around the support shaft to drop and eject items within the range stored therein, and store items outside the range. The bucket is a bucket conveyor configured to drop or discharge an item outside the range accommodated when the bucket is rotated around the support shaft by the bucket tilting member provided on the most downstream side. In In the case and the discharging mechanism, the bucket tilting member is urged downward by the urging means, is normally in the lower engagement position, and is movable upward by contact with the guide piece. A bucket and a discharging mechanism in a bucket conveyor.

[0020]

[Operation] The bucket rotatably supported by the support shaft is
Since the opening is always facing upward in the suspended state, it can be inserted from any position. Especially, in the vertical transfer path part, since the guide piece is in contact with the vertical guide member, the posture of the bucket is more Stabilize. In addition, when the product is discharged, the bucket is engaged with the engaging member at a predetermined location according to the weight of the product by the operation of the electromagnetic solenoid that is excited corresponding to the result of weighing the product, and the product falls downward. . When you eject the item,
The opening of the bucket faces upward due to its own weight. Further, by arranging the electromagnetic solenoids that are excited in accordance with the weighing result of the items sequentially on the downstream side according to the size of the weighing result, the items can be sorted downward according to the order of the weighing result. Further, the bucket containing an item with a weight outside the predetermined range discharges the item contained when rotated by the bucket tilting member on the most downstream side. When the bucket is rotated by the bucket tilting member, a force in a direction against the biasing means acts on the outer bucket tilting member, so that the impact force applied to the bucket from the bucket tilting member can be absorbed.

It is fitted with b and is similarly attached with rivets 91, 91 and the like. As shown in FIG. 3, the bucket 35 to which the guide piece 37 and the chain attachment piece 38 are attached has a guide piece 37 on the pair of shaft locking portions 41, 41 formed at predetermined intervals of the two-way chain 33. Align the shaft locking holes 39, 40 of the chain mounting piece 38 with each other. Then, the guide piece 37
7, the shaft 51 is inserted through the spacers 49 and 50 between the two-strand chain 33 and the spacer 52 between the chain attachment piece 38 and the two-strand chain 33.
The shaft 54 is inserted through 53, whereby the bucket 3
5 is positioned on the two-strand chains 33, 33 and is rotatably supported. In such a suspended state of the bucket 35, the front wall portion 35c and the rear wall portion 35d are inclined upward depending on the position of the center of gravity.

In this way, in the transporting device 20 of the embodiment, four rows of five double-strand chains 33, 33, 33, 33, 33 wound around the gear devices 23, 24, 25, 26 are continuously arranged. The bucket conveyor is configured.

In this way, when the bucket conveyor is of multiple type, the buckets 35 and 3 adjacent to each other are provided.
One double-strand chain 33 is arranged between the five, and the double-strand chain 33 also serves to support the adjacent buckets 33, 33. Therefore, in the embodiment, four rows of buckets are supported by five two-strand chains.

On the other hand, in the upper horizontal transfer path portion of the gantry 22, as shown in FIGS. 8 and 9, above the pair of two-strand chains 33, 33, each has a U-shaped cross section in the chain conveying direction. Extending along and mounting flanges 59a, 59
A solenoid mounting member 59 having b in the opening is fixedly installed on a stationary portion such as a device frame. On the bottom plate 59c of the solenoid mounting member 59, a plurality of large holes 60 and small holes 61 are formed at predetermined intervals in pairs except one on the most downstream side, and one set on the most downstream side is formed. Has no large holes. The solenoid mounting plate 59 has a mounting flange portion 5
The 9a and 59b and the device frame are bolted together to be integrally assembled, and the position is adjusted in the long hole 62.

A predetermined number (8 in the embodiment) of electromagnetic solenoids 64 are accommodated in a space 63 defined by the solenoid mounting member 59. These electromagnetic solenoids are screwed to the bottom plate 59c of the mounting member 59. It is fixed. Figure 1
As shown in 0, an engagement member 66 is attached to the actuator 65 of the electromagnetic solenoid 64. Engaging member 66
Is formed in a substantially L shape from the short side arm portion 73 and the long side arm portion 68 with the connecting portion 72 having the rotating shaft 67 as a boundary. The rotating shaft 67 is rotatably supported by a fixed plate (not shown) arranged so as to hang down from the solenoid mounting member 59. At a tip portion of the long side arm portion 68 of the engaging member 66, a substantially L-shaped hook portion 70 having a cutout portion 69,
A rod portion 71 extending downward from the hook portion 70 is formed. A torsion coil spring is built in the connecting portion 72.

In the engaging member 66 thus formed, the short side arm portion 73 is inserted into the large hole 60 from below the solenoid mounting member 59, and the hook portion 70 of the long side arm portion 68 is small. It is inserted in the hole 61 and is installed in the solenoid mounting member 59. Even if an external force for rotating the long side arm portion 68 in the counterclockwise direction about the rotating shaft 67 in FIG. 10 acts on the long side arm portion 68, when the force is released, the spring of the torsion coil spring is engaged. The force causes it to return clockwise and restore the natural state of the torsion coil spring. When the engaging member 66 rotates, the one end portion 70a of the hook portion 70 and the one end portion 71a of the rod portion 71 come into contact with the bottom plate 59c of the solenoid mounting member 59, whereby the rotation range of the engaging member 66 is increased. Regulated.

As described above, each electromagnetic solenoid 64, to which the engaging member 66 is attached below, is connected to a controller (not shown) and is excited in response to a command from the controller. The electromagnetic solenoid 64 operates the actuator 6 in the normal non-excitation state.
5 is at the broken line position in FIG. 10, and at this time, the long-side arm portion 68 of the engaging member 66 has the one end portion 71 of the rod portion 71.
a is in contact with the bottom plate 59c of the solenoid mounting member 59. That is, it is in the upper position. When the electromagnetic solenoid 64 is energized from such a non-excited state, the actuator 65 is in the solid line position, and at the same time, the engaging member 66 is in the lower position as illustrated. At that time, one end 70a of the hook portion 70 comes into contact with the bottom plate 59c of the mounting member 59, but the hook portion 70
By attaching a cushioning material 58 such as urethane rubber to the portion that comes into contact with the one end portion 70a, generation of abnormal noise due to collision is prevented. Similarly, if a cushioning material 74 is attached to a portion that abuts the one end portion 71a of the rod portion 71 when the engaging member 66 is at the upper position, abnormal noise due to a collision at the time of ending the excitation is generated. Occurrence can be prevented.

On the other hand, at the most downstream portion of the solenoid engaging member 66 attached to the eight electromagnetic solenoids 64, as shown in FIG. 11A, the trigger case 80 hangs down from the bottom plate 59c of the attaching member 59. A bucket tilting member 81 is rotatably supported on the trigger case 80. The bucket tilting member 81 is formed integrally with the main arm portion 82 that extends in a substantially horizontal direction, the support shaft 83 that rotatably supports the main arm portion 82, and the other end portion of the main arm portion 82. Sub arm portion 8 extending in the vertical direction
4 and a bent portion 8 formed at the upper end of the sub arm portion 84.
4a and the engaging portion 8 formed at the lower end portion of the sub arm portion 84.
5 and a weight portion 86 such as a bolt and a nut attached to the bent portion 84a. The support shaft 83 of the tilting member 81 is rotatably supported by the trigger case 80. Further, the tilting member 81 is
Normally, it is at the lower position as shown in A of FIG. 11, and a clockwise rotational urging force acts on the support shaft 83.

The bucket tilting member 8 thus formed
1 is a bent portion 84a from below the solenoid mounting member 59.
Is inserted into the small hole 61, and the solenoid mounting member 59
It is installed in. When an external force for rotating the tilting member 81 in the counterclockwise direction in A of FIG. 11 acts on the main arm portion 82, the bending portion 84a takes the upper position as shown in B of FIG. 11 and the force is released. , And returns in the clockwise direction by the weight portion 86. When the tilting member 81 rotates, the bent portion 84a and the engaging portion 85 come into contact with the bottom plate 59c of the solenoid mounting member 59, thereby restricting the rotation range of the tilting member 81. At that time, the solenoid mounting member 59
By attaching a cushioning member such as urethane rubber 87, 88 to both surfaces of the bottom plate 59c, the generation of noise due to a collision is prevented.

As described above, under each electromagnetic solenoid 64 arranged at the predetermined position of the solenoid mounting member 59, a collecting chute 76 divided into a plurality of parts by a partition plate 75.
, And each chute of the collecting chute 76 corresponds to one of the upper electromagnetic solenoids 64. A container or the like is arranged below these chutes.

A carrying device 20 having a bucket and a discharging mechanism installed in a bucket conveyor according to an embodiment of the present invention.
The transporting device 20 is used as a sorting device based on the weight of marine products such as scallop scallops or tarako, although it is configured as described above. Hereinafter, the operation of the carrier device 20 that sorts the same type of marine products by weight will be described.

Now, the motor 27 is driven and the gear device 23
To 5 rows of double-strand chains 33, 33, 33, 33, 33
The power is transmitted to the other gear devices 24, 25, 26 via the. Therefore, the four rows of bucket conveyors are supported by the two double-strand chains 33, 33 so that the conveyor 20
It is transferred in the direction of arrow B in FIGS. 1 and 2. The eight electromagnetic solenoids 64, 64, ... 64 are
All are in the non-excited state, and the corresponding engaging members 66 are all in the upper position. On the other hand, one scallop scallop or the like is weighed to one by a weighing means (not shown). Then, the scallops and the like after the weight measurement are carried by the bucket 3 which conveys the vertical transfer path portion between the gear device 26 and the gear device 23 in the conveying device 20.
5 are supplied to one. In this vertical transfer path portion, the bucket 35 has the curved portion 3 of the guide piece 37 as shown in FIG.
7a and 37b abut the vertical guide member 55, which guides the traveling in the vertical direction, so that the posture is kept constant. That is, even if an article such as a scallop is put into the bucket 35 from the vertical transfer path in this way,
Does not rock. In the embodiment, the scallops and the like put into the bucket 35 are divided into nine groups, of which eight groups correspond to one electromagnetic solenoid. Which group the scallops belong to is input to the controller by weighing. And the scallop scallops and the like that have been weighed are transferred to this transport device 2
They are sorted by weight by 0 and are grouped in the lower container. The sorting operation will be described below.

Eight groups by weight correspond to any electromagnetic solenoid. After accommodating the scallops or the like in the bucket, the travel distance of the two-row chain 33 until reaching the corresponding electromagnetic solenoid is calculated by a pulse encoder or the like, and after a predetermined time, the corresponding electromagnetic solenoid 64 is excited for a predetermined time. It has become. When the electromagnetic solenoid 64 is excited, the actuator 65 and the engaging member 66 in FIG. 10 are brought into the state shown in the figure, and the rod portion 71 is moved forward in the traveling direction of the rear wall portion 35d of the desired bucket 35 which is going to pass immediately below. Will be placed. Therefore, the bucket 35
Travels with the rear wall portion 35d in contact with the rod portion 71 of the engaging member 66, so that the bucket 35 rotates counterclockwise about the shafts 51 and 54 in FIG.
The scallop scallop that was housed is the lower collecting chute 7
6 is dropped to an appropriate position and stored in a container or the like.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is excited, and the scallops pass through the chute and are housed in containers of different weights. Therefore, the scallop scallops are sorted by weight within a predetermined range and housed in a container or the like. Further, the bucket 35 after dropping the article is conveyed with some vibration thereafter, and reaches the engaging portion 85 of the bucket tilting member 81 arranged on the most downstream side. When reaching the engaging portion 85, the guide piece 37 comes into contact with this and the bucket 35 rotates again. Therefore, even if the electromagnetic solenoid 64 does not operate, the items remaining in the bucket are reliably discharged at this position.

On the other hand, the buckets containing the weights of the remaining groups which do not belong to the above eight groups pass through all the electromagnetic solenoids and reach this position. Touch and drop the item downward. Therefore, the goods are discharged from all the buckets.

When the bucket 35 comes into contact with the bucket tilting member 81 as described above, since most of the buckets are after the articles have been dropped by the rotation, those buckets move forward and backward with the shafts 51 and 54 as fulcrums. The tilting member 81 is reached in a shaken state. Therefore, depending on the rotating posture of the bucket, it is conceivable that, when the bucket comes into contact with the tilting member 81, a large thrusting force is applied to the supporting portion of the bucket, the tilting member, or the double chain. However, since the bucket tilting member 81 is rotatable by the support shaft 83 as described above, when a large force acts on the tilting member 81 from the bucket 35 via the guide piece 37, the tilting member 81 is moved to the position shown in FIG. It rotates counterclockwise from the state A and shifts to the state B in FIG.

Therefore, the thrust force is absorbed by the rotation,
Damage to the guide pieces etc. is prevented. After rotating the bucket, the bucket tilting member 81 returns to the lower position again by the urging force of the weight portion 86.

Further, when the bucket 35 after dropping the article by the electromagnetic solenoid reaches the tilting member 81 in a relatively stable posture, when it reaches the tilting member 81 via the guide piece 37,
The force acting on the tilting member 81 via the guide piece 37 is small, and when this force is smaller than the rotation biasing force by the weight portion 86, the tilting member 81 does not rotate, and therefore a stable posture is obtained. As shown in FIG. 11A, the bucket 35 comes into contact with the tilting member 81 that holds the lower position and rotates.

When the bucket 35 finishes carrying the stored items, the front wall portion 35c and the rear wall portion 35d are returned to the upward inclination by their own weight, and the remaining horizontal transfer passage portion and the vertical transfer passage portion downwardly move. , Traveling on the lower horizontal transfer path, again
The posture is maintained by the guide piece 37, and the guide piece 37 transfers the vertical movement path portion between the gear device 26 and the gear device 23.

FIG. 12 shows the essential parts of another embodiment of the present invention. In this embodiment, a torsion coil spring 89 is wound around the support shaft 83 of the bucket tilting member 81,
One end of the spring 89 is locked to the bottom plate 59c of the solenoid mounting member 59, and the other end is locked to a notch provided in the main arm portion 82. Due to the biasing force of the torsion coil spring 89 in the clockwise direction in FIG.
By locking a with the bottom plate 59c of the solenoid mounting member 59, it is held at the position shown.

Further, in the above embodiment, the article, that is, the scallops of the scallops are put in the vertical transfer path portion of the bucket conveyor, but may be put in the horizontal transfer path portion from above.

In the above embodiment, the guide piece 37 extending substantially vertically and the L-shaped chain attaching piece 38 are attached to the bucket 35. However, both of the guide pieces 37 extending substantially vertically extend. Also good. In that case, it is necessary to provide two vertical guide members 55 for one bucket in the vertical transfer path portion, but the bucket 35 can be held more stably when the product is loaded. Further, when the two guide pieces 37 are used together, it is not necessary to form a new hole in the bucket 35, and the bucket 35 is attached by using the holes 36a, 36b and 36c.

Further, in the above embodiment, the electromagnetic solenoid 64 corresponding to the result of the weighing machine is set according to the range of the result of the weighing machine without particularly determining the order of the magnitude of the weighing result. I tried to excite, but instead of this,
In order from the upstream side, the weighing results are increased from small to large, that is, the weighing results are <a, <b, <c, <d ...
(A <b <c <d ...) Similarly, heavier items may be sorted toward the downstream side and discharged to the outside by a chute corresponding thereto.

In this case, obviously, the weight of the article is a or less, from a to b in order from the chute on the downstream side to the upstream side.
Range, b to c range, c to d range,
Similarly, when a large number of electromagnetic solenoids are arranged in the same manner as in the following example, the products within a predetermined weight of each, for example, scallops are discharged to the outside, so that the products are finely packed in a box and the price is determined. be able to.

In the above embodiment, a large number of electromagnetic solenoids are arranged along the horizontal transfer path of the bucket. However, only two electromagnetic solenoids are provided, and items smaller than the weight a are stored in the bucket. When it is conveyed, the upstream solenoid is excited to discharge a product having a weight a or less to the outside from a chute corresponding to the solenoid, and then a bucket containing a product smaller than b (b> a) is When the solenoid arrives at the downstream side, the downstream side solenoid may be excited to discharge the corresponding product and discharge it from the corresponding chute to the outside. Further, if not the electromagnetic solenoid but the engaging member is simply fixed on the downstream side, all the buckets are emptied and guided to the right vertical transfer path portion in FIG. In this way
From the chute on the downstream side, it is possible to supply a weight M within a predetermined range (a <M <b), for example, for packaging scallops.
