It is rotatably supported by 33. Such a bucket 35
In the suspended state, 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 carrier device 20 of the embodiment, four rows of continuous chains between the five double-strand chains 33, 33, 33, 33, 33 wound around the gear devices 23, 24, 25, 26 are continuously formed. The bucket conveyor is configured.

On the other hand, in the upper horizontal transfer path portion of the gantry 22, as shown in FIGS. 12 and 13, above the pair of double-stranded chains 33, 33, each has a U-shaped cross section in the chain conveying direction. Along which the mounting flange 59 extends
A solenoid mounting member 59 having openings a and 59b is fixedly installed on the apparatus frame. On the bottom plate 59c of the solenoid mounting member 59, a plurality of pairs of large holes 60 and small holes 61 are formed 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 long hole 62.

A predetermined number (eight in this example) of electromagnetic solenoids 64 are housed 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. 14
As shown in, the engaging 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 provided with 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 the tip 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 rotation shaft 67 in FIG. The force causes it to return clockwise and return to 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 the controller 200 and excited in response to a command from the controller. The controller 200 is supplied with a weighing signal of the load cell 111 described later. In the electromagnetic solenoid 64, the actuator 65 is in the position of the broken line in FIG. 14 in the normal non-excited state, and at this time, the long side arm portion 68 of the engaging member 66 is moved to the rod portion 7.
One end 71a of the bottom plate 59 of the solenoid mounting member 59
It is in contact with c. 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 at the solid line position, and at the same time, the engaging member 66 is at the lower position as shown. At that time, one end portion 70a of the hook portion 70 abuts on the bottom plate 59c of the mounting member 59, but by attaching a cushioning material 58 such as urethane rubber to a portion of the hook portion 70 abutting on the one end portion 70a, a difference due to a collision may occur. Generation of sound is prevented. Similarly, the engaging member 66
If the cushioning material 74 is attached to a portion that comes into contact with the one end portion 71a of the rod portion 71 when is located at the upper position, it is possible to prevent abnormal noise from being generated due to a collision when the excitation is finished.

As described above, under each electromagnetic solenoid 64 arranged 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.
, And each chute of the collecting chute 76 corresponds to one of the upper electromagnetic solenoids 64. Further, a sorting container is arranged below the chutes.

Next, FIG. 16 shows the mechanism for discharging the weight of scallops.
~ It demonstrates with reference to FIG.

In FIGS. 16 and 17, the lever crank mechanisms 91 and 91 'are symmetrically arranged and have the same structure. Therefore, only one lever crank mechanism 91 will be described.

This forms a so-called four-bar rotation mechanism,
It consists of book links, one of which is fixed. That is, the bearing box 92 is arranged on the base 105, and the shaft 94 fitted to the inner ring of this bearing extends to the other lever crank mechanism 91 'and integrates them. The shaft 98 fixed to the inner ring of the other bearing box 93 is also shown in FIG.
As shown in FIG. 5, it 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 portion of a lever lever 95 is rotatably coupled to the shaft 94, and the upper end portion is supported by a bearing 96 as a pivot point and a lever 97 as a connecting rod.
Is fixed to the right end of the bearing box 93, a crank plate 99 is rotatably attached to the shaft 98 of the other bearing box 93 at its lower end, and the inner ring side of the bearing box 100 is fixed to this upper end. The outer ring side is fixed to the above-mentioned lever 97 by a bolt 102 at the upper end of this bearing box 100. Further, the rotating shaft 10 fixed to the inner ring side of the bearing box 100.
1 is fixed to the crank plate 99. With such a structure, the shaft 98 is rotated clockwise by the driving of the chain belt 30 wound around the pulley of the motor 27 of FIG. 6, and the crank plate 99 is rotated in the same manner as indicated by the locus C. I am supposed to do it.

As described above, the lever crank mechanism 91
However, the other lever crank mechanism 9
1'is also bilaterally symmetric, and thus has the same configuration. A connecting plate 103 is fixed to the left end of the lever 97, which 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' are adapted to perform the same movement in synchronization.

As shown in FIG. 16, the connecting plate 13 is provided with three substantially rectangular discharge plates 114 as the second plate member, in this embodiment, three spacers 1 as shown in FIG.
10 are interposed and fixed at a predetermined pitch. That is, these discharge plates 114 perform the same movement as the lever 97. In order to allow the discharge plates 114 to pass through the gaps S between them, a weighing plate 107 as a first plate member having a substantially ladle shape as shown in FIG. 108, 10
9 are commonly fixed, and these shafts 108, 10
Both ends of 9 are fixed to the weight connecting plates 106a and 106b hanging from the load cell 111. The load cell 111 is fixed to an upper stationary portion S ′, and is a known Roberval mechanism, which vertically connects the weight connecting plate 10 to the weight connecting plate 10.
It is configured to receive a force applied to 6a and 106b. The weighing plate 107 has a substantially ladle shape as described above, and due to this shape, the article receiving portion T having a substantially V-shaped cross section is constituted by these three plate members. As shown above, for example, scallop M is received. In addition, although the discharge plate 114 is also composed of three sheets in this example, these perform the operations described later, and the chain supply conveyor 78 is provided on the left side of these, as shown by the arrow. The scallops M are supplied one by one, and the scallops M received in the article receiving portion T by the operation of the discharge plate 114 as described later are indicated by an arrow a in the process of the discharge plate 114. The bucket conveyor 3 arranged on the right side of the
It is adapted to be supplied to the bucket 35 which is being transferred by the second vertical transfer section.

6 and 7, the weighing mechanism 9 for the article
On the upstream side of 0, a scallop chain supply conveyor 78 formed by connecting a number of elements having a V-shaped cross section is arranged in four rows in this example as shown in FIG. And, although only the drive chain gear 79 is shown in this figure, it receives the drive force of the pulley 81 via the chain belt 80 '. Further, this pulley 81 is attached to a frame 82 fixed to a frame, which is wound around a pulley of the motor 27 which is the above-mentioned drive source via a chain belt 83. Therefore, scallop chain supply conveyor 7
8 is driven at a predetermined speed and 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 device 20 having the bucket conveyor according to the present embodiment is constructed as described above, and the device 20 is used as a sorting device based on the weight of marine products such as scallop scallops or tarako. The operation of the device 20 for sorting such seafood of the same type by weight will be described below.

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, which are supported between the two double-strand chains 33, 33, are transferred in the apparatus 20 in the direction of arrow B in FIGS. 6 and 7. 8
64 are all in the non-excited state, and the engaging members 66 corresponding thereto are all in the upper position. On the other hand, scallop scallops etc. have a weighing mechanism 9
One is weighted by 0. Then, the weighed scallops and the like are placed in the bucket 35 that conveys the vertical transfer path portion between the gear device 26 and the gear device 23 in the device 20.
Supplied individually. In this vertical transfer path part, the bucket 35 is
As shown in FIG. 11, the curved portions 37a, 3a of the guide piece 37,
7b comes into contact with 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 in the vertical transfer path, the bucket 35 does not rock. In this example, the scallops and the like put into the bucket 35 are sorted into eight groups by the weight, and to which group the scallops belong, after weighing,
It is input to the controller 200. Then, the weighed scallop scallops and the like are sorted by weight by the device 20 and housed in groups in the lower container. The sorting operation will be described below.

The group by weight corresponds to any electromagnetic solenoid. After accommodating the scallops and the like in the bucket, the travel distance of the two-way 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 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 that is about to pass directly below. Will be placed. Therefore, the bucket 35 travels with the rear wall portion 35d abutting on the rod portion 71 of the engaging member 66, so that the bucket 35 has the shafts 51, 5 in FIG.
It rotates counterclockwise about 4, and thereby the scallops of the scallops that have been stored fall into appropriate positions on the lower collecting chute 76 and are stored in the container.

Thereafter, similarly, in the succeeding bucket, a predetermined electromagnetic solenoid is excited, and the scallops pass through the chute and are accommodated in containers by weight. Therefore, the scallop scallops are sorted by weight within a predetermined range and housed in a container or the like.

When the bucket 35 finishes carrying the stored items, the front wall portion 35c and the rear wall portion 35d return to the upward inclination due to their own weight, and the vertical transfer path portion downward from the remaining horizontal transfer path portion, and After traveling along the lower horizontal transfer path, the posture is again held by the guide piece 37, and the vertical transfer path between the gear device 26 and the gear device 23 is transferred.

The bucket conveyor of this example performs the above-mentioned operations, but has the following effects.
That is, when marine products or the like are transported, regular cleaning is performed for hygiene, but the electric electromagnetic solenoid 64 is
Since it is located above the device, it is easy to wash with water or the like. Further, the processing capacity can be freely set by the rotational force of the motor 27, the number of arranged bucket conveyors, and the like.

Further, in the above example, the bucket 35 is automatically rotated about the shafts 51 and 54 as a fulcrum when moving from the vertical transfer path to the horizontal transfer path and vice versa, and when dropping the scallop scallops. Since the front wall portion 35c and the rear wall portion 35d are inclined upward, no complicated resetting means is required.

The lever crank mechanisms 91 and 91 'are constructed as described above. When the shaft 98 is rotated at a constant speed, the shaft 1 fixed to the crank plate 99 is thereby produced.
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 about the shaft 94 from the position shown in FIG. 15 by an angle. The lever 97 takes the position as shown in FIG. 17 via the shaft 96 connected thereto, so that the discharge plate 110 fixed to this left end also takes the position shown. When it is further rotated by 45 degrees, that is, when it is rotated by 90 degrees from the phase of FIG. 15, it takes the position shown in FIG. 18, the lever 95 further swings rightward around the shaft 94, and the lever 97 moves rightward. At the same time, its left end moves downward. Therefore, the discharge plate 110 fixed to this end takes the position shown.

When it further rotates 45 degrees, it takes the position shown in FIG. 19, and in this phase, the lever 95 changes its moving direction to the left and swings. Along with this, the lever 97 moves to the left, but the left end portion further falls downward, and the discharge plate 110 fixed to this also takes a position where it falls downward. Further rotation by 45 degrees, that is, 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 about the axis 94 and is therefore pivotally attached thereto. The lever 97 being moved also moves to the left, and the discharge plate 110 fixed to this left end portion further falls downward. When it is further rotated by 45 degrees, it takes the position shown in FIG. 21, and the lever 95 swings further to the left around the shaft 94. Therefore, the lever 97 connected thereto also swings to the left, and both are slightly moved. It begins to rise upwards. When it is further rotated 45 degrees, it takes the position shown in FIG. 22, and the lever 95
Moves slightly to the left about axis 94. As a result, the discharge plate 110 takes the position shown. When it is further rotated by 45 degrees, it takes the position shown in FIG. 23, and this time, the lever 95 largely swings around the shaft 94, and this movement also causes the lever 97 to largely move to the right and also to move upward. Moving. Therefore, the discharge plate 110 also moves largely accordingly. When it is further rotated by 45 degrees, the lever 95 swings largely to the right around the shaft 94, and along with this, the lever 97 also moves to the right, and at the same time, its left end portion largely moves upward. Therefore, the initial rotation 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 locus C by the uniform rotational motion of the shaft 93. This is done by 114. On such a stroke, the rotation phase is 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 material during the stroke. One scallop M is supplied from the left chain supply conveyor 78, which is shown in FIG.
It is placed as shown in FIG. Therefore, these three weighing plates 107 are integrated and are coupled to the pair of weighing coupling plates 106a and 106b extending upward at both ends thereof, so that they are coupled to their upper ends. At this time, the weight of the scallop M placed on the article receiving portion T is measured by the load cell 111 present. Then the discharge plate 112
Moves in the locus as described above, but the scallop M on the article receiving portion T is weighed and the short edge portion 114a of the discharge plate 114 is rotated in the rotation phase between the rotation phases shown in FIGS.
Then, the scallop M received by the receiving portion T is pushed out as shown in FIGS. 23 and 15. Therefore, as shown in FIG. 15, the vertical portion of the bucket conveyor 32 arranged 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
Of the scallop M is supplied from the chain supply conveyor 78 one by one, so that the next bucket 35 is surely in a position to receive the next scallop.

As described above, although the mechanism proposed above can reliably weigh and discharge the goods to the bucket, the lever crank mechanisms 91, 91 'are four-bar rotation mechanism, and link mechanism. Also, since there are four pivot shafts each, it is difficult to ideally process and assemble them, and a small noise or assembly error causes a large noise, and the vibration is considerably large.

[0036]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a weighing / discharging mechanism for articles, which reduces noise and vibration.

[0037]

[Means for Solving the Problems] The above object is an article receiving portion in which a plurality of weighing plate members are arranged at intervals, and the upper edge portion of these weighing plate members receives an item supplied from above. And a weighing device that weighs the weight of the goods received by the goods receiving portion is connected to the weighing plate material, and a plurality of discharges are provided so as to pass through the intervals of the weighing plate material. When the discharging plate material passes through the gap by the rotation of the drive shaft having the plate material attached at a predetermined angular position at a predetermined speed, the article weighed by the weighing device on the article receiving portion is discharged. The bucket traveling direction is downward in the vertical traveling portion of the bucket conveyor in which the bucket for pushing the ejected article is attached at a predetermined pitch by pushing the plate material to eject the article from the article receiving portion. Depending on the weighing and discharging mechanism It is achieved.

Alternatively, a plurality of weighing plates are arranged at intervals, and an article receiving portion for receiving an article supplied from above is formed at an upper edge portion of these weighing plates, and the article receiving portion receives the articles. A weigher that weighs the weight of the product is connected to the weighing plate, and a plurality of pairs of discharge plates that face each other in the radial direction are predetermined so as to pass through the intervals of the weighing plate. When the discharge plate passes through the gap by the rotation of the drive shaft attached at the angular position of, the product weighed by the scale on the product receiving section is pushed by the discharge plate. The buckets for receiving the discharged articles at a predetermined pitch, and the bucket traveling direction in the vertical traveling section of the bucket conveyor is set downward. Achieved by heavy / eject mechanism It is.

[0039]

With the rotation of the drive shaft at a predetermined speed, the discharging plate member can push the weighed product on the weighing plate member and supply it to the next process, for example, to the bucket of the bucket conveyor. Since only the discharge plate and the drive shaft to which it is attached move, and only rotation is performed, the product can be discharged with almost no noise or vibration.

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

Further, since the bucket is traveling downward in the vertical traveling portion of the bucket conveyor for receiving the goods, the vertical traveling portion of the bucket conveyor can be arranged as close as possible to the weighing plate material or the discharging plate material side. Therefore, the time taken for the goods in the goods receiving section to be discharged into the bucket can be shortened as much as possible, and the weighing efficiency can be improved.

Is moved to the right in the figure along with, and is pushed to the chute portion 219c over the protruding portion 219b of the weighing plate member 219. At this time, the blade 222c reaches the rotational phase as shown in FIG. 2 or FIG. 3, and the scallop M moves to the weighing plate member 21.
It slides along the chute part 219c of No. 9 and is discharged from the lower end to the bucket 35 which is adjacent 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 180 degrees from this, but from the supply conveyor 223 so far. The next scallop M is supplied to the one-piece product receiving portion T, and its weight has already been measured by the load cell main body 215.
The other blade 222c reaches the position shown in FIG. 1, where the scallop M, which is housed in the article receiving portion T and already weighed, is pushed on the article receiving portion T and the weighing plate 21
9 is dropped on the chute portion 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. These are the protruding portions 219a of the four weighing plate members 219,
It is received by the article receiving portion T formed by 219b, the weight is weighed by the load cell main body 215, dropped by the blades 222b, 222c to the chute portion 219c, and slides there, one by one in the bucket 35 one by one. It is being supplied.

While the above-described operation is performed, the three ejecting plate members 222 are fixed to the drive shaft 212, and the blades 222b and 222c are formed in these in a radial symmetrical manner. , The center of gravity is eccentric, but these cancel each other out. Therefore, the drive shaft 21
No unbalanced load is applied to No. 2, vibration due to imbalance is not generated, and no noise is generated.

Although the one-row bucket conveyor 32 has been described above, as described above, in the four-row bucket conveyor, the goods are supplied to the article receiving portions T in synchronism with each other, they are weighed at the same time, and almost simultaneously, the weighing plate 219. Since it is supplied from the lower end of the chute section 219c to the buckets 35 that are lining up in a horizontal row, weighing and sorting can be performed efficiently, noise and vibration are less than in the conventional case, and each part of the apparatus is Since an unbalanced load is not applied to
Prolong the life of the device.

According to the present invention, the following effects are also obtained.

That is, the bucket conveyor has a structure as shown in FIGS. 6 to 11 as a whole, and the vertical traveling portion is shown in FIGS. 1 to 4. However, according to the present invention, the bucket 35 in this vertical traveling unit is traveling in the direction indicated by the arrow, that is, downward, unlike the above-mentioned proposed example. That is, the rotation direction of the motor that drives this bucket conveyor is reversed. 1 to 4
As shown by, the discharge plate 222 rotates clockwise, and its blades 222b, 222c have a locus L indicated by a chain line.
1 to 4, the rotation locus L intersects with the linear locus drawn by the left end portion of the bucket 35 traveling downward, as shown in FIGS. However, according to the present invention, as shown in the drawing, even if the vertical traveling portion of the bucket conveyor 32 is extremely close to the article receiving portion T side as described above, it is possible to prevent collision with each bucket 35 in the bucket conveyor 32. Absent. Now, the 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, when the blade 222b is in the illustrated rotation phase, the scallop M is transferred from the product supply conveyor 223 to the product receiving portion T.
The blade 222b moves the scallop M from the article receiving portion T and rotates the scallop M as shown in FIG. The portion 219c is slid, and FIG. 2 shows this sliding process. In FIG. 1, buckets A, B, C
Both are quite far from the blades 222b, 222c. Further, in FIG. 2, the blade 222b is close to the bucket 35A, and the bucket 35B is close to the lower end of the chute portion 219c of the weighing plate member 219.
However, there is no conflict. 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. However, there is no conflict. At this time, the blade 222c is closest to the left end of the bucket 35. Then, as shown in FIG. 4, when the blade 222c further rotates 45 degrees, the blade 222 is rotated.
c largely separates from the bucket 32A. As shown in FIG. 3, the scallop M is just entering the bucket 35B. And, in the rotational phase of the blade 222c of FIG. 4, it is already housed in the bucket 35B. When the blade 222c is further rotated clockwise by 45 degrees as described above, the blade 222c assumes the position shown in FIG. 1, and the other blade 222c has already been supplied to the article receiver T.
And the same operation as described above is performed.

As described above, even though the vertical traveling portion of the bucket conveyor 32 is arranged very close to the article receiving portion T side, since the bucket 35 is traveling downward, the blades 222b and 222c are not connected to each other. There is no collision.

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

As described above, the weighing of the article according to the embodiment of the present invention
Although the discharging device has been described, it goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made 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 ensures that the product on the product receiving portion T can be discharged. It should be noted that although noise and vibration are larger than those in the embodiment, they are greatly reduced as compared with the prior art. Further, as in the case of the embodiment, assembling is easier than in the prior art, but the weighing time of the product can be made longer than that of the embodiment, so that more reliable weighing of the product can be performed. That is, it is assumed that the goods are supplied from the goods supply conveyor 123 to the goods receiving section T at a rate of one per second. Blades 222b, 222
When c is only one (one side), 7/8 = 0.87
The weighting time can be taken for 5 seconds, but in the case of being provided as a pair on both sides (in the case of the embodiment), 3/4 =
It is 0.75 seconds, which is slightly shorter. In this respect, a blade having only one side is more advantageous.
