A pair of shaft locking portions 41, 4 formed at predetermined intervals of 3.
1 is matched with the shaft locking holes 39 and 40 of each guide piece 37 and the chain mounting piece 38. Then, the guide pieces 37 and 2
The shaft 51 is inserted through the spacers 49 and 50 between the chain 33, and the shaft 54 is inserted through the spacers 52 and 53 between the chain attachment piece 38 and the double chain 33. 35 is a two-row chain 33,
33 to be rotatably supported. Such a bucket 35
In the suspended state, the front wall 35c and the rear wall 35d are inclined upward depending on the position of the center of gravity.

As described above, in the conveying device 20 of the embodiment, four rows of continuous chains 33, 33, 33, 33, 33 wound around the gear units 23, 24, 25, 26 are arranged in four rows. Bucket conveyor is constructed.

On the other hand, as shown in FIGS. 12 and 13, the upper horizontal transfer path portion of the gantry 22 is located above the pair of two-chain chains 33, 33, and has a U-shaped cross section in the chain transport direction. Extending along the mounting flange 59
A solenoid mounting member 59 having a and 59b provided in the openings is fixedly installed on the apparatus frame. A plurality of pairs of large holes 60 and small holes 61 are formed on the bottom plate 59c of the solenoid mounting member 59 at predetermined intervals. The solenoid mounting plate 59 is integrally assembled by bolting between the mounting flange portions 59a and 59b and the device frame, and the position is adjusted by the elongated holes 62.

A predetermined number (eight in this embodiment) of electromagnetic solenoids 64 are accommodated in a space 63 defined by the solenoid mounting member 59, and these electromagnetic solenoids are screwed onto a bottom plate 59 c of the mounting member 59. Fixed. FIG.
As shown in (1), 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 a short side arm portion 73 and a long side arm portion 68 with a connecting portion 72 provided with a rotating shaft 67 as a boundary. The rotating shaft 67 is rotatably supported by a fixing plate (not shown) provided to hang down from the solenoid mounting member 59. At the tip of the long side arm 68 of the engaging member 66, a substantially L-shaped hook 70 having a notch 69,
A rod portion 71 extending downward from the hook portion 70 is formed. The connecting portion 72 has a built-in torsion coil spring.

In the engagement member 66 thus formed, the short side arm 73 is inserted into the large hole 60 from below the solenoid mounting member 59, and the hook 70 of the long side arm 68 is small. And is installed in the solenoid mounting member 59. Even if an external force that rotates counterclockwise around the rotation shaft 67 in FIG. 14 acts on the long arm portion 68 in FIG. 14, the engagement member 66 releases the spring of the torsion coil spring when the force is released. It returns in the clockwise direction by the force and returns to the natural state of the torsion coil spring. When the engagement member 66 is rotated, one end 70a of the hook 70 and one end 71a of the rod 71 abut against the bottom plate 59c of the solenoid mounting member 59, and thereby the rotation area of the engagement member 66 is reduced. Be regulated.

As described above, each electromagnetic solenoid 64 having the engaging member 66 attached below is connected to the controller 200 and is excited according to a command from the controller. The controller 200 is supplied with a weighing signal of a load cell 111 described later. In the electromagnetic solenoid 64, in a normal non-excited state, the actuator 65 is located at a broken line position in FIG.

The actuator 65 is in the solid line position, and at the same time, the engagement member 66 is in the lower position as shown. At this time, one end 70a of the hook 70 comes into contact with the bottom plate 59c of the mounting member 59, but the cushioning material 58 such as urethane rubber is attached to a portion of the hook 70 that comes into contact with the one end 70a. The generation of sound is prevented. Similarly, the engagement member 66
If the cushioning material 74 is adhered to the portion that comes into contact with the one end portion 71a of the rod portion 71 when is at the upper position, it is possible to prevent the generation of abnormal noise due to the collision at the time when the excitation is completed.

Below each electromagnetic solenoid 64 disposed at a predetermined position of the solenoid mounting member 59, a collecting chute 76 divided into a plurality of parts by a partition plate 75 is provided.
Are arranged, and each chute of the collecting chute 76 corresponds to one of the upper electromagnetic solenoids 64. A sorting container is arranged below these chutes.

Next, the scallop weighing discharge mechanism is shown in FIG.
This will be described with reference to FIGS.

In FIGS. 16 and 17, the lever crank mechanisms 91 and 91 'are symmetrically disposed and have the same configuration, so that only one lever crank mechanism 91 will be described.

This forms a so-called four-bar rotation mechanism.
It has a structure in which one of the links is fixed. That is, a bearing box 92 is disposed on the base 105, and a shaft 94 fitted to the inner ring of the bearing extends to the other lever crank mechanism 91 ', and these are integrated. A shaft 98 fixed to the inner ring of the other bearing box 93 is also shown in FIG.
As shown in the figure, the lever lever is connected to the other lever crank mechanism 91 '. The inner ring of the bearing box 93 is coaxial with the pulley 28 in the figure.

A lower end of a lever 95 is rotatably coupled to the shaft 94. The upper end of the lever 94 is connected to a bearing 96 as a pivot point and a lever 97 as a connecting rod.
A crank plate 99 is rotatably mounted at the lower end of the shaft 98 of the other bearing box 93, and the inner ring side of the bearing box 100 is fixed to the upper end of the crank plate 99. The outer ring is fixed to the above-mentioned lever 97 by a bolt 102 at the upper end of the bearing box 100. A rotating shaft 10 fixed to the inner ring side of the bearing box 100
1 is fixed to the crank plate 99. With this configuration, the shaft 98 is rotated clockwise by the drive of the chain belt 30 wound around the pulley of the motor 27 shown in FIG. It is supposed to do it.

As described above, the lever crank mechanism 91
The other lever crank mechanism 9
1 'is also symmetrical, so it is similarly configured. A connecting plate 103 is fixed to the left end of the lever 97, and is connected to one end of a connecting rod 97 ′ corresponding to the lever 97 in FIG. 16 of the other lever crank mechanism 91 as shown in FIG. The levers 97 and 97 'of the lever crank mechanisms 91 and 91' make the same movement in synchronization.

As shown in FIG. 16, the connecting plate 13 is provided with a discharge plate 114 as a substantially rectangular second plate material. In this embodiment, as shown in FIG.
10 and is fixed at a predetermined pitch. That is, the discharge plates 114 perform the same movement as the lever 97. Also, as shown in FIG. 16, a weighing plate 107 as a substantially scoop-shaped first plate member is also provided with a spacer block 112 interposed therebetween so that the discharge plates 114 can pass through the gap S between them. 108, 10
9, and these shafts 108, 10
9 are fixed to the weighing connection plates 106a and 106b hanging from the load cell 111. The load cell 111 is fixed to the upper stationary part S ′ and has a known Roberval mechanism.
It is configured to receive a force applied to 6a, 106b. The weighing plate 107 has a substantially ladle shape as described above. With this shape, an article receiving portion T having a substantially V-shaped cross section is constituted by these three plate members. As shown above, for example, scallops M are received. Also, in this example, the discharge plates 114 also consist of three sheets, which perform an operation as described later, and a chain supply conveyor 78 is provided on the left side thereof, as shown by an arrow. The scallops M are configured to be supplied one by one, and the scallops M received by the goods receiving portion T by the operation of the ejection plate 114 as described later are indicated by an arrow a during the stroke of the ejection plate 114. The bucket conveyor 3 disposed on the right side
The second vertical transfer section supplies the bucket 35 to the transferring bucket 35.

In FIG. 6 and FIG.
On the upstream side of "0", scallop chain supply conveyors 78 in which a number of V-shaped cross sections are connected are arranged in four rows in this example as shown in FIG. Although only the drive chain gear 79 is shown in this figure, it receives the driving force of the pulley 81 via the chain belt 80 '. The pulley 81 is attached to a frame 82 fixed to a gantry. The pulley 81 is wound around a pulley of the motor 27 as a driving source described above via a chain belt 83. Therefore, the scallop chain supply conveyor 7
8 is driven at a predetermined timing with the transfer speed of the bucket conveyor 32 according to the diameter ratio and the number of teeth of the pulley 81 and the drive chain gear 79.

The apparatus 20 provided with the bucket conveyor according to the present embodiment is configured as described above, and the apparatus 20 is used as a sorting apparatus based on the weight of marine products such as scallops or tarako. The operation of the apparatus 20 for sorting the same kind of seafood by weight will be described below.

Now, the motor 27 is driven and the gear train 23
To five rows of two-row chains 33, 33, 33, 33, 33
Power is transmitted to the other gear devices 24, 25, 26 via the. Therefore, supported by the two double-row chains 33, 33, four rows of bucket conveyors are transported in the apparatus 20 in the direction of arrow B in FIGS. 8
The electromagnetic solenoids 64, 64,... 64 are all in the non-excited state, and the corresponding engaging members 66 are all in the upper position. On the other hand, scallop scallops are weighing mechanism 9
One is weighed by 0. The weighed shell and the like are placed in a bucket 35 that is transporting a vertical transfer path between the gear device 26 and the gear device 23 in the device 20.
Supplied individually. In this vertical transfer path, the bucket 35
As shown in FIG. 11, the curved portions 37a, 3
7b abuts on the vertical guide member 55, thereby guiding the traveling in the vertical direction, so that the posture is kept constant.
That is, even if articles such as the scallop are thrown into the bucket 35 in the vertical transfer path, the bucket 35 does not swing. In this example, the scallops and the like thrown into the bucket 35 are classified into eight groups by weighing, and after weighing,
It is input to the controller 200. The weighed scallops of scallop and the like are sorted by weight by this device 20 and stored in groups in the lower container. The sorting operation will be described below.

The group by weight corresponds to one of the electromagnetic solenoids. After the shells and the like are accommodated in the bucket, the travel distance of the double 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. 14 are in the state shown in the drawing, and the rod portion 71 moves forward of the rear wall 35d of the desired bucket 35 which is going to pass immediately below. Be placed. Therefore, the bucket 35 travels with the rear wall portion 35d abutting against the rod portion 71 of the engaging member 66, so that the bucket 35 has the shafts 51, 5 in FIG.
The scallop scallop contained in the scallop is dropped to an appropriate position of the lower collecting chute 76, and is accommodated in the container.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is excited, and the scallop passes through the chute and is accommodated in a container or the like by weight. Therefore, the scallops of the scallops are sorted by weight within a predetermined range and stored in a container or the like.

When the bucket 35 completes the transfer of the contents, the front wall 35c and the rear wall 35d return to the upward inclination by their own weight, and the vertical transfer path from the remaining horizontal transfer path to the lower part, and After traveling on the lower horizontal transfer path portion, the posture is again held by the guide piece 37, and is transferred on the vertical transfer path portion between the gear device 26 and the gear device 23.

The bucket conveyor of the present embodiment performs the above-described operations, but has the following effects.
That is, when transporting marine products and the like, regular washing is performed for sanitation, but the electric electromagnetic solenoid 64 is
Since it is located above the apparatus, cleaning with water or the like is easy. Further, the processing capacity can be set freely according to the rotational force of the motor 27, the number of arranged bucket conveyors, and the like.

In the above example, when the bucket 35 moves from the vertical transfer path to the horizontal transfer path, and vice versa, and when the scallops of the scallops are dropped, the bucket 35 automatically rotates about the shafts 51 and 54 as fulcrums. Since the front wall 35c and the rear wall 35d are inclined upward, no complicated resetting means is required.

The lever crank mechanisms 91 and 91 'are configured as described above. When the shaft 98 is rotated at a constant speed, the shaft 1 fixed to the crank plate 99 is thereby rotated.
01 rotates at a constant speed along the locus C. This shaft 101 takes the position shown in FIG. 17 when rotated 45 degrees from the phase shown in FIG. The lever 95 swings from the position shown in FIG. The lever 97 takes the position shown in FIG. 17 via the shaft 96 connected thereto, so that the discharge plate 110 fixed to the left end also takes the position shown. Further rotation by 45 degrees, that is, rotation by 90 degrees from the phase of FIG. 15, takes the position shown in FIG. 18, the lever 95 further swings to the right around the shaft 94, and the lever 97 moves to the right. At the same time, the left end moves downward. Therefore, the discharge plate 110 fixed to this end takes the position shown in the figure.

Further rotation by 45 degrees takes the position shown in FIG. 19, and in this phase, the lever 95 changes its moving direction to the left and swings. At the same time, the lever 97 moves to the left, but the left end further falls downward, and the discharge plate 110 fixed thereto takes the position where it falls downward. Further rotation 45 degrees, ie 180 degrees from the rotation phase of FIG. 15, takes the position shown in FIG. 20, in which the lever 95 swings to the left around the axis 94 and is therefore pivotally connected to it. The lever 97 is also moved to the left, and the discharge plate 110 fixed to the left end falls further downward. When rotated further 45 degrees, the lever 95 assumes the position shown in FIG. 21 and the lever 95 swings further leftward around the shaft 94, and the lever 97 connected thereto also swings leftward, and both of them slightly move. Start to rise upwards. When rotated further 45 degrees, it takes the position shown in FIG.
Moves slightly around the axis 94 to the left. As a result, the discharge plate 110 assumes the illustrated position. Further rotation by 45 degrees takes the position shown in FIG. 23, whereby the lever 95 swings greatly around the shaft 94, and this movement also causes the lever 97 to move significantly to the right and both upwardly. Moving. Therefore, the discharge plate 110 also moves greatly in response. When the lever 95 further rotates by 45 degrees, the lever 95 swings largely to the right around the shaft 94, and at the same time, the lever 97 also moves to the right, and the left end thereof largely moves upward. Therefore, the initial rotational phase shown in FIG. 15 is taken.

As described above, the crank plate 99 fixed to the shaft 93 moves along the stroke indicated by the trajectory C by the constant-speed rotation of the shaft 93. 114 is performed, during such a stroke, in a rotational phase as shown in FIG. 18, or on the article receiving portion T formed on the upper side of the weighing plate 107 as the first plate during the stroke. One scallop M is supplied from the left chain supply conveyor 78.
It is placed as shown in FIG. Therefore, these three weighing plates 107 are integrated, and are connected to a pair of weighing connecting plates 106a and 106b extending upward at both ends thereof. At this time, the weight of the scallop M placed on the article receiving portion T is weighed by the load cell 111 that is present. Next, the discharge plate 112
Moves in the above-described trajectory, but the scallop M which is weighed and is in the goods receiving section T is rotated at a rotation phase between the rotation phases shown in FIGS.
As shown in FIGS. 23 and 15, the scallop M received by the receiving portion T is pushed out. Therefore, as shown in FIG. 15, the vertical portion of the bucket conveyor 32 disposed on the right side is dropped and supplied to one of the buckets 35 being transferred as shown by an arrow a.

The bucket 35 of the bucket conveyor 32
Is coincident with the supply timing of the scallops M supplied one by one from the chain supply conveyor 78, so that the next bucket 35 is surely at the position for receiving the next scallops.

As described above, with the mechanism proposed earlier, the article can be reliably weighed and discharged to the bucket. However, the lever crank mechanisms 91 and 91 'are four-bar rotating mechanisms, and Since there are four pivot shafts each, it is difficult to ideally process and assemble, and a small processing error or assembling error generates a large noise, and the vibration becomes considerably large.

[0036]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems, and has as its object to provide a mechanism for weighing / discharging an article with less noise and vibration.

[0037]

SUMMARY OF THE INVENTION It is an object of the present invention to dispose a plurality of weighing plates at intervals and to receive an article supplied from above at an upper edge of the weighing plates. And a weighing device for weighing the weight of the article received by the article receiving portion is provided in combination with the weighing plate, and a plurality of dischargers are provided so as to pass through each interval of the weighing plate. By rotating the drive shaft at a predetermined speed with the plate material attached to a predetermined angular position, the articles weighed by the weighing device on the article receiving portion when the discharge plate material passes through the interval are used for the discharge. It is characterized in that the bucket traveling direction in the vertical traveling section of the bucket conveyor in which the buckets receiving the discharged articles are attached at a predetermined pitch is directed downward by being pushed by the plate material and ejected from the article receiving section. Weight and discharge mechanism It is achieved.

Alternatively, a plurality of weighing plates may be arranged at intervals, and an article receiving portion for receiving an article supplied from above at an upper edge portion of the weighing plates may be formed. A weighing device for weighing the weight of the weighed product is provided in combination with the weighing plate, and a plurality of pairs of diametrically opposed discharge plates are passed through each interval of the weighing plate. The rotation of the drive shaft mounted at the angular position at a predetermined speed causes the articles weighed by the weighing device to be pushed by the weighing device on the article receiving section when the ejection plate passes through the gap. A bucket running direction in a vertical traveling portion of the bucket conveyor, in which buckets for receiving the discharged articles are attached at a predetermined pitch, are directed downward. Achieved by heavy and discharge mechanism It is.

[0039]

With the rotation of the drive shaft at a predetermined speed, the discharging plate can push the weighed article on the weighing plate and supply it to the next step, for example, to a bucket of a bucket conveyor. Only the discharge plate and the drive shaft to which it is mounted move, and only the rotation is performed. Therefore, there is almost no noise or vibration, and the product can be discharged.

In particular, when a pair of discharge plates in the radial direction are attached to the drive shaft, the unbalanced mass distribution is eliminated, so that the product can be discharged very quietly and without vibration.

In the vertical traveling portion of the bucket conveyor for receiving articles, the bucket travels downward, so that the vertical traveling portion of the bucket conveyor can be disposed as close as possible to the weighing plate or discharge plate. Therefore, it is possible to shorten the time required for the articles in the article receiving section to be discharged into the bucket as much as possible and to increase the weighing efficiency.

[0042]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an article weighing / discharging mechanism according to an embodiment of the present invention will be described with reference to FIGS. The parts corresponding to the conventional example are denoted by the same reference numerals.

In the figure, the horizontal arm 21 of the frame F is shown.
0a and 210b have a pair of bearing housings 211.
a and 211b are fixed, and the drive shaft 212 is rotatably supported at both ends thereof.

In this embodiment, as in the example described above, 4
32 rows of bucket conveyors will be described, but only one row is shown in the figure, and this will be described.

The vertical arms 213a, 21 of the frame F
A load cell housing 214 is fixed to 3b, and has a U-shaped cross section. A load cell main body 215 is fixed to the housing 214 at one end thereof by a mounting member 216. At one end of the wall, one end of a weighing plate 219 described later is fixed. The load cell main body 215 is configured in a known manner, and has a rectangular shape as a whole, but is formed with two substantially circular shapes and a notch portion 218 formed of a substantially rectangular shape notch connecting the two. The so-called Roberval mechanism is constructed,
Even though the vertical load applied to the load cell 17 is not shown, the load is measured by a strain gauge fixed to the upper wall surface of the load cell main body 215.

According to the present embodiment, the weight member 219 is attached to the mounting member 217 of this one load cell main body 215.
One end is fixed as shown in FIG. 2,
The overall shape is as shown in FIG.
The first protruding portion 219 is formed so as to form a character-shaped article receiving portion T.
a and a second projecting portion 219b, and a chute portion 219c connected to the projecting portion 219b so as to form a runway surface extending toward the bucket conveyor 32. In the weighing plate 219 having such a shape, four weighing plates 219 are integrated by a shaft 224 at one protruding portion 219a, and a shaft 221 is provided at a lower end of the chute 219c.
Are integrated. Therefore, one product, for example, scallops M is supplied from the supply conveyor 223 onto the product receiving portion T formed by the respective projecting portions 219a and 219b of these four weighing plates 219.
This single item of scallops M is composed of these four weighing plates 2
19, and / or any of them, can receive the weight, so that a common load cell body 21
5 weighs the weight.

As shown in FIG. 5, each weighing plate 219
A discharge plate 222 is provided in such a gap S, and a circular boss 222a is formed in the center of the discharge plate 222. Drive shaft 212 is inserted and fixed at the center thereof. Blades 222b and 222c are integrally fixed on both sides of the boss portion 222a, that is, at positions opposing each other in the radial direction. These blades have the same shape, but have a point-symmetrical shape. This blade 2
22b, 222c are formed facing the rotation direction,
The rear end face q is formed to be inclined with respect to this.

The drive shaft 212 rotates clockwise in FIG. 1 at a predetermined speed by a motor (not shown). On the other hand, the bucket 35 of the bucket conveyor 32 moves downward at a predetermined moving speed, and supplies the scallops M one by one from the article supply conveyor 222 to the article receiving section T at predetermined time intervals. On the other hand, the discharge plate member 222 rotates clockwise, but when one of the blades 222b reaches the rotation phase as shown in FIG. 1, the scallops M on the article receiving portion T are rotated by this rotation. The receiving surface T of the article receiving portion T is pushed by the portion P.
Along the right side in the figure, and is pushed to the chute portion 219c beyond the protruding portion 219b of the weighing plate 219. At this time, the blade 222c reaches the rotation phase as shown in FIG. 2 or FIG.
9 slid along the chute portion 219c, and is discharged from the lower end to the bucket 35 that is in proximity at this time.
On the other hand, the other blade 122c of the discharge plate 222 has reached the rotation phase of the one blade 222b as shown in FIG. 1, and the one blade 222b has already advanced by 180 degrees from this. The next scallop M is supplied to the item receiving portion T, and the weight thereof has already been weighed by the load cell main body 215.
When the other blade 222c reaches the position shown in FIG. 1, the scallop M, which is housed in the article receiving section T and has already been weighed, is pushed on the article receiving section T, and the weighing plate 21 is moved.
9 is dropped on the chute 219c. It slides here and is supplied to the next bucket 35 from this lower end.

As described above, the scallops M are supplied one by one from the supply conveyor 223 at a predetermined pitch. This is because the projecting portions 219 a of the four weighing plate members 219 are provided.
The weight is received by an article receiving portion T formed by the load cell 219b, the weight is weighed by the load cell main body 215, dropped to the chute portion 219c by the blades 222b and 222c, and slid there, sequentially one by one into the bucket 35. It is being supplied.

The drive shaft 212 performs the above-described operations, and three discharge plate members 222 are fixed to the drive shaft 212. Since the blades 222b and 222c are formed symmetrically in the radial direction on these, the discharge plate members 222 are formed. The center of gravity is eccentric, but these offset each other. Therefore, the drive shaft 21
No uneven load is applied to No. 2, no vibration due to unbalance occurs, and no noise is generated.

While the single row bucket conveyor 32 has been described above, the four row bucket conveyors are supplied to the article receiving portions T synchronously and weighed at the same time, and almost simultaneously, the weighing plate 219 as described above. Is supplied to the buckets 35 arriving side by side in a row from the lower end of the chute portion 219c, so that weighing and sorting can be performed efficiently, noise and vibration are reduced as compared with the related art, and each part of the device is also provided. Because no offset load is applied to
Extend the life of the device.

According to the present invention, the following effects can be further obtained.

That is, the bucket conveyor has the configuration as shown in FIGS. 6 to 11 as a whole, and this vertical traveling portion is shown in FIGS. 1 to 4. However, according to the present invention, the bucket 35 in this vertical traveling section travels in the direction indicated by the arrow, that is, downwards, unlike the above-mentioned proposed example. That is, the rotation direction of the motor that drives the bucket conveyor is reversed. 1 to 4
, The discharge plate member 222 rotates clockwise, and its blades 222b and 222c move along a trajectory L indicated by a dashed line.
The rotation locus L intersects with the linear locus drawn by the left end of the bucket 35 traveling downward as shown in FIGS. However, according to the present invention, even when the vertical traveling portion of the bucket conveyor 32 is extremely close to the item receiving portion T as shown in the drawing, it is possible to collide with each bucket 35 of the bucket conveyor 32. Absent. Now, a related motion between the bucket 35 and the blades 222b and 222c will be described. In order to distinguish the buckets 35, they are denoted by A, B and C from above as shown in FIG. As shown in FIG. 1, the blade 222b is in the illustrated rotation phase, and the scallops M are transferred from the article supply conveyor 223 to the article receiving section T.
It is assumed that the weight has already been weighed, but the blade 222b moves the scallops M from the article receiving portion T and rotates the scallops M as shown in FIG. The part 219c is slid, and FIG. 2 shows this way. In FIG. 1, buckets A, B, C
Both are far apart from the blades 222b, 222c. 2, the blade 222b is approaching the bucket 35A, and the bucket 35B is approaching the lower end of the chute 219c of the weighing plate 219.
However, there is no collision. Next, as shown in FIG. 3, the blade 222b further rotates 45 degrees from the rotation phase of FIG. It is closest to the bucket 35A. But there is no collision. At this time, the blade 222c is closest to the left end of the bucket 35. Then, as shown in FIG.
c is far away from the bucket 32A. As shown in FIG. 3, the scallop M has just entered the bucket 35B. In the rotation phase of the blade 222c in FIG. 4, the blade 222c is already housed in the bucket 35B. When the blade 222c further rotates clockwise by 45 degrees as described above, the blade 222c assumes the position shown in FIG.
And performs the same operation as described above.

As described above, since the bucket 35 travels downward despite the vertical traveling portion of the bucket conveyor 32 being disposed very close to the item receiving portion T side, the blades 222b and 222c are There is no collision.

As described above, the scallops M are pushed out from the article receiving portion T disposed close to the chute portion 219c by the blade, and the scallops M are thrown from the discharge end into the bucket 35 adjacent thereto. However, since the length of the chute portion 219c can be shortened, if the scallops M still exist on the chute portion 219c, one accurate one of the scallops M supplied in the goods receiving section T is used. Although the weight cannot be detected, the scallops M are supplied to the bucket from the lower end of the weighing plate shortly after the scallops M are discharged from the article receiving portion T.
Can be supplied to the article receiving portion T to accurately measure the weight. As described above, according to the present invention, the scallops M can be sequentially supplied to the article receiving portion T at a high speed.
The weight of each piece can be accurately measured and supplied to the bucket 35 sequentially.

As described above, the weighing of an article according to the embodiment of the present invention
Although the discharge device has been described, it is needless to say that the present invention is not limited to the above embodiment, and various modifications are possible based on the technical idea of the present invention.

For example, the blade 222 of the discharge plate 222
One of b and 222c may be omitted. This also allows the articles on the article receiving section T to be reliably discharged. Although noise and vibration are generated more than in the embodiment, the noise and vibration are greatly reduced as compared with the related art. Also, as with the embodiment, the assembly is easier than before, but the weighing time of the article can be longer than that of the embodiment, so that the weighing of the article can be performed more reliably. That is, it is assumed that the articles are supplied from the article supply conveyor 123 to the article receiving section T at a rate of one piece per second. Blade 222b, 222
If c is only one (one side), 7/8 = 0.87
A weighing time of 5 seconds can be taken, but if a pair is provided on both sides (in the case of the embodiment), 3/4 =
0.75 seconds, slightly shorter. In this respect, a blade with only one side is more advantageous.

[0058]

As described above, according to the article weighing / discharging apparatus of the present invention, regardless of the shape of the article to be weighed or discharged, the article is reliably received and weighed. Can be weighed, and the discharge or supply to the bucket from now on can be made fast and smooth.
While exhibiting such effects, noise and vibration hardly occur.
