CONSTITUTION:A number of trays 9 are mounted on a horizontal chain 2A of a selecting device, the tray 9 is in an up state in a feed position, and inclined in a discharge position. The lower end of a rotary shaft 32 of an intermediate sprocket 31 engaged with the chain 2A forms a crank part 33, and a shaft 35 coupled through rotation of a crank part 33 is reciporcatively moved. The reciprocating movement causes rotation of a ratchet wheel 43 through levers 38, 41, and 42 and the ratchet wheel is rotated only during outboud movement of the shaft 35 and intermittently rotated. Through intermittent rotation thereof, a feed conveyor 40 is intermittently driven. When the tray 9 is conveyed to the feed port of the feed conveyor 40, the feed conveyor 40 is driven, and an object A to be selected is reliably dropped on the tray 9.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a feeding device for a sorting device.

More specifically, the present invention provides a method for sorting fruits such as grapes, grapes, and mandarin oranges, vegetables such as tomatoes, potatoes, and carrots, and marine products such as fish and shrimp, particularly for supplying objects to be sorted to an apparatus for weight sorting. Regarding the device.

C. Prior Art] The present inventor has developed a weight sorting device that swings between a horizontal position in which objects to be sorted are placed and held on a tray and an inclined discharge posture in which the objects to be sorted are dropped and discharged. A lever for an upper pan scale that can freely swing around an axis; a moving means for supporting the swinging axis and moving the lever for the upper pan weight along a sorting route; a weight sorting location on the sorting route; a rail that engages with the force point of the lever and restricts the swinging of the lever; a first position that holds the lever in a horizontal position, and a rail that holds the lever in an inclined position that is more gentle than the release inclined position; proposed a weight sorting device characterized by comprising a counterweight applying device that moves a rail between a second position and a second position according to the weight of the objects to be sorted (see Japanese Utility Model Publication No. 1-124278). .

With this device, objects to be sorted can be weight-sorted accurately, efficiently, and quickly. However, in this device, the objects to be sorted are manually supplied to the receiving tray.

[Problem to be solved by the invention]

Devices for supplying objects to be sorted to a sorting device are disclosed in Japanese Utility Model Publication No. 63-26220 and Japanese Utility Model Publication No. 1-1 and 8223.

Japanese Utility Model Publication No. 63-26220 discloses a fruit sorting machine in which a conveyor section supplies agricultural products one by one to a sorting body of a sorting section to sort the agricultural products. This fruit sorting machine is characterized in that rollers are arranged in parallel at a constant pitch on an endless band, and a narrow rod 11 narrower than the rollers is arranged between these rollers, and there is no flow from the feeding device. This is to prevent the objects to be sorted from being caught between the rollers of the supply device when the objects to be sorted are delivered to the sorting device.

However, if such a device is used in the above-mentioned practical
When applied to the weight sorting device of Publication No. 24278,
It is necessary to very delicately adjust the timing between the tray of the weight sorting device and the feeding device, and as a practical matter, the objects to be sorted fed by the feeding device are not placed properly on the tray of the sorting device.

In particular, when the receiving tray is moved in a horizontal plane in the apparatus of Japanese Utility Model Publication No. 1-124278, the object to be sorted is moved from the supply device that continuously moves toward the receiving tray that is continuously moving horizontally. Therefore, it is extremely difficult to match the timing of both.

In addition, in the device disclosed in Japanese Utility Model Publication No. 1-18223, a large number of holding bodies for agricultural products are arranged in parallel on an endless conveyor, and while the holding bodies are conveyed by the endless conveyor,
a sorting device that sorts agricultural products held in the holding body;
In a sorting machine for agricultural products, which includes a feeding device that supplies agricultural products to the holder, the feeding device is an endless container with a plurality of supports for agricultural products arranged in parallel, and the agricultural products are transferred from the supports to the holder. This is a sorting machine for agricultural products characterized by the following: the supply device and the sorting device each consist of a plurality of conveyors, and the objects to be sorted are passed between the plurality of conveyors.

After all, when this device is applied to the device described in the above-mentioned Utility Model Publication No. 1-124278, it is very difficult to adjust the timing between the sorting device and the feeding device, and as a practical matter, it is difficult to adjust the timing of the sorting device to the sorting device. The only thing that doesn't go well is the delivery of the object.

In particular, when the receiving tray is moved in a horizontal plane in the apparatus of Utility Model Publication No. 1-124278, the object to be sorted is moved from the supply device that continuously moves toward the receiving tray that is continuously moving horizontally. Therefore, it is extremely difficult to match the timing of the two.

[Purpose of the invention]

In view of the above-mentioned problems, the present invention has a simple structure, allows the objects to be sorted supplied to the supply vc to be fed one by one onto the trays of the sorting device without manual intervention. The present invention also provides a feeding device for a sorting device that is very easy to adjust.

[Means to solve the problem]

In the present invention, the above-mentioned problem can be solved by constructing a sorting device drive system in which an endless chain is wound around a sprocket, and a large number of sorting device bodies including trays for sorting objects are attached to the chain. The screen includes a supply device or a supply conveyor for supplying the objects to be sorted to the sorting device, and converts the continuous motion of the sorting device drive system into intermittent motion to convey the feed conveyor to the sorting device. This is achieved by a feed device of the sorting device, characterized in that the sorting device drive system and the supply converter are connected by a converter for transmitting the information to the sorting device.

[For production]

In the present invention, the continuous motion in one direction of the chain or sprocket of the sorting device drive system of the sorting device is converted into intermittent motion by the converting device and transmitted to the supply conhair of the feeding device. For this reason, the supply conveyor of the supply device operates intermittently, and since the sorting device and the supply device are mechanically connected by a conversion device, the supply conveyor of the supply device is operated intermittently to match the receiving surface of the sorting device. By intermittent operation, the objects to be sorted can be properly fed one by one from the supply device to the tray of the sorting device in accordance with the timing when the tray reaches a predetermined position.

〔Example〕

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

In the first embodiment of the present invention, the chain 2A of the sorting device drive system moves in a substantially horizontal plane,
A conversion device is provided between the intermediate sprocket 3 having a crank mechanism that engages the horizontal chain 2A and converts the unidirectional continuous motion of the horizontal chain 2A into reciprocating motion, and the crank mechanism and the supply conveyor 40. , consisting of a unidirectional motion member that transmits unidirectional motion during reciprocating motion to the supply conveyor.

As shown in FIGS. 1 and 3, the feeding device of this embodiment feeds fruits such as grapes, grapes, mandarin oranges, tomatoes, and potatoes in a direction substantially perpendicular to the moving direction of the horizontally moving chain 2A of the sorting device. The feeder is intermittently moved in one direction in synchronization with the sorting device, and is fed to the tray 9 of the sorting device. The objects to be sorted A are fed two by two from the feeding device when they reach the outlet of the device.

That is, in FIG. 3, a chain 2A with an attachment is connected in an endless manner and meshed with a pair of horizontal sprockets 30 rotatably supported at both left and right end positions in FIG. 3 to constitute an elliptical moving means 2. ing. One of the two horizontal linear portions (FIG. 3) located parallel to each other and facing each other in the moving means 2 constitutes a sorting path.

One of the pair of horizontal sprockets 30 is driven by a drive motor (
(not shown) to move the drive means 2 in the direction of the arrow in FIG.

A plurality of levers 1 (balance levers) for an upper plate balance are attached to the moving means 2, and a receiver [rll 9] is attached to each lever 1.

A plurality of weight sorting points are provided along the straight portion of the moving means 2. In addition, at the upstream position of the weight sorting point,
The feeding device 40 of the present invention selects and selects the objects A or the tray 9
Supplied on top.

The feeding device 40 of this embodiment extends orthogonally to the moving direction of the chain with attachment 2A, and its structure will be described later.

Each weight sorting point has a loading guide rail 5 on the entrance side.
However, a rail 3 is provided at each weight sorting location, and a transfer guide rail 6 and a braking means 8 are provided on the exit side thereof. Note that the transfer guide rail 6 provided at the weight sorting location on the upstream side of a pair of adjacent weight sorting locations may be integrally continuous with the transfer guide rail 5 on the downstream side. Further, a weight applying means 4 is provided inside each weight sorting location.

Corresponding to the braking means 8 on the exit side of each weight sorting location, a chute 22 for receiving the sorted object A from the lever 1 swung to the discharging inclined position is provided at an outer position of the moving means 2.

As shown in FIGS. 5 and 6, a large number of brackets 12 are attached to the attachment of the chain 2A with attachments of the moving means 2, and a sixth
As shown in the figure, a lever 1 is supported so as to be swingable around a swing axis R.

A vertical saucer support bar 1a is pivotally attached to the tip of the lever 1 by a pin IC, and the lower end of the vertical saucer support bar 1a and the bracket 12 are connected by a lever 1b and pins ld and le to constitute a horizontal rank mechanism, The tray support vertical rod 1a always maintains a vertical state.

A tray 9 for placing the object to be sorted A is placed on the tray support vertical bar 1a.
When the lever 1 rotates (as shown by the chain line in FIG. 6), the tray 9 tilts greatly and discharges the objects A to be sorted into the chute 22.

A stopper 7 (FIG. 6) attached to the bracket 12 holds the lever 1, which has swung to the ejecting tilted position, in that position.

A roller 13 with a circumferential groove is rotatably supported on the rear side of the bracket 12, and a guide rail 2 is mounted along the sorting route.
B is provided, and the guide rail 13 is engaged with the groove of the roller 13 (FIG. 6).

A blade member 10 biased by a spring 10b is pivotally attached to the other end of the lever 1 by a pin 10a.

The blade member 10 slides into contact with the transfer guide rail 5 on the entrance side of the weight sorting location, with the rail 3 at the weight sorting location, and with the transfer guide rail 6 or the braking means 8 on the exit side depending on the sorting result. . While in sliding contact with the rail 3, a preset counterbalance weight acts on the blade member 10 (force point a) by the weight applying means 4.

The rail 3 engages with the force point a (blade-like member 10) of the lever 1 that has moved to the weight sorting point on the sorting route, and the weight set in the counterweight applying device 4 and the weight of the sorted object A are engaged. The swinging of lever 1 is restricted according to the weight, and the following two positions are taken. That is, (1) When the weight placed on the tray 9 is less than the set value, the lever 1 is held in a horizontal position so as to place and hold the object A to be sorted on the tray 9 in the first position shown in FIG.

(2) When the weight placed on the tray 9 is equal to or greater than the set value, the lever 1 is held in the second position shown in FIG. 8, with the lever 1 in an inclined position that is more gentle than the ejecting inclined position.

The weight applying device 4 is fixedly installed inside the moving means as shown in FIG. 3, and its structure will be explained below with reference to FIGS. 7 and 8.

Fixed bracket 2 that can swing freely around lever 15 or axis X1
It is supported by 3. Vertical frame 18 on lever 15 is axis center X2
The lower end of the vertical frame 18 is connected to the fixed bracket 23 by a link 19 and pins 19a and 1.9b to form a horizontal rank mechanism, and the vertical frame 18 is always maintained in a vertical position. .

The vertical t9!18 has a receiving tray 17 for the weight 16 at its upper end, and is attached to the rail 3 or the vertical frame 18 at right angles to the middle part.

At the weight sorting point, when the weight of the object A placed on the receiving tray 9 of the lever 1 transferred thereto is less than the set value of the weighting device 4, the rail 3 is moved as shown in FIG. It remains lowered (first position), and lever 1 maintains a horizontal position. On the other hand, when the weight of the object A to be sorted is more than the set value of the weight applying device 4, the rail 3 is raised to the second position (as shown in FIG. 8), and the lever 1 is placed in an inclined position. Therefore, it is possible to weight sort the objects A by using the set value of the weighting device 4 as a threshold value.

A plurality of weight sorting points equipped with rails 3 (!: weight applying devices 4) are formed in the middle of the sorting route, and the weight applying devices are arranged from upstream to downstream when viewed in the direction of chain movement. The set weight of No. 4 is gradually decreased.

Next, the supply device 40 of this embodiment will be explained.

As shown in FIGS. 1 and 3, an intermediate sprocket 31 rotatably supported by a bearing 32 (FIG. 2) is engaged with an endlessly connected chain 2A of the sorting device drive system of the sorting device. are combined.

The lower end of the rotating shaft of the intermediate sprocket 31 is bent into a U-shape to form a crank portion 33.
is pivotally connected to a crank lever 34.

The rear end of the crank lever 34 is connected to the front end (right end) of a shaft 35, and the shaft 35 is connected to a fixedly installed guide 3.
It is movable in the front-back direction along 6. The rear end (left end) of the shaft 35 is a lever 3 that can swing around a fulcrum 370.
A bottle 39 is connected to one end (lower end) of the bottle 8.

The other end (upper end) of the lever 38 is a ratchet wheel 43
A rod-shaped lever 41 is attached to an arm 42 that is integrally connected to the
, connected by connecting rods or wires.

In the illustrated embodiment, a ratchet wheel 43 is formed with four sawtooth inclined pawls 43a, and the ratchet wheel 43 has a pin 4.
A pivotable bowl (claw) 45 is latched around the 4.

When the chain 2A of the sorting device drive system rotates in one direction,
The intermediate sprocket 31 engaged therewith also rotates in one direction, thereby causing the crank portion 33 and the crank lever 34 to rotate in one direction.
makes a crank motion. This crank movement causes the shaft 35 to reciprocate back and forth along the guide 36.

This reciprocating motion is transmitted to the ratchet wheel 43 via the lever 38, rod 41, and arm 42, and when the ratchet wheel 43 moves in one direction, the ratchet wheel 43 is rotated in one direction without being hindered by the pawl 45, and when it moves in the other direction, the pawl 45 rotates. This prevents the ratchet wheel 43 from rotating. This causes the ratchet wheel 43 to rotate in one direction intermittently.

As shown in FIG. 1, the feeding device of this embodiment consists of a box 45 that is perpendicular to the transfer direction of the sorting device and tilted upward toward the sorting device, and is rotatable to the front and back positions of the box 45. A pair of shafts 46 are also provided.

The ratchet wheel 43 mentioned above is attached to the lower shaft 46.

In the illustrated embodiment, two left and right sprockets 47 are respectively attached to the front and rear shafts 46, and left and right chains 48 with attachments are endlessly stretched between the front and rear sprockets 47. Further, a vertical partition wall 50 (FIG. 3) is provided between the left and right chains 48 to divide the inside of the box into two regions, left and right.

Between the two left and right chains with attachments 48, locking members made of horizontal crosspieces, preferably rotatable rollers 49, etc. are provided at regular intervals. The roller 49 is
Preferably, it is made of PVC rollers, which are inexpensive, lightweight, and easy to clean.

As shown in FIG.
A guide plate 5o is provided extending in the moving direction of the chain 48 at a predetermined distance from the lower surface of the roller 49 or in contact with the lower surface of the roller 49.

With the above configuration, the sprocket 46 of the supply device is intermittently rotated in one direction by the continuous rotation of the chain 2A of the sorting device drive system in one direction, and the chain 48 with attachments moves intermittently together with the roller 49 accordingly. Therefore, the sorting target A supplied to the lower part of the box body 45 is transferred to the roller 49 attached between the chains 48 with attachments.
pushed upwards by

By appropriately selecting the interval between the rollers 49 according to the type and size of the objects A to be sorted, one object to be sorted can be separated between each roller 49 in each area divided by the partition wall 50. There must be an A. If there are more objects A to be sorted, they will fall over either the upper object A or the lower object A and fall down. For this reason, one object to be sorted A is placed between all the tenor rollers 49.

At this time, if the gap between the adjacent rollers 49 is larger than the object to be sorted A, the object to be sorted A is placed on the guide plate 50 below the roller 49. Due to the movement of the roller 49, the object to be sorted A is placed on the guide plate 50. to be transferred.

For this reason, the objects to be sorted A are rolled around on this guide plate 5°. On the other hand, if the gap between the rollers 49 is smaller than the object to be sorted A, the object to be sorted A will be
rest on top of. In this case, by keeping the roller 49 in contact with the guide plate 50, the roller 49 rolls on the guide plate 5o as it moves, and rolls the object A to be screened.

Therefore, the operator can inspect the sorting object A rolling on the guide plate 50 or the roller 49 to see if there are any scratches or the like, and can remove any defects. Note that another object to be sorted A is placed in the place where it has been removed.

Then, the objects A to be sorted are intermittently pushed up by the rollers 49, and fall onto the tray 9 of the sorting device from the upper end when the empty tray 9 is positioned below the outlet of the supply device.

A swing plate 52 is pivotally attached to the tip of the box body 45 by a pin 51, so that the object to be sorted A is surely placed on the tray 9 without flying out of the tray 9.

Incidentally, by selecting the ratio of the number of teeth between the intermediate sprocket 31 and the sprocket 30, and while the roller 49 advances one pitch, a number of receivers 11119 corresponding to the number of objects A to be sorted are selected.
is being moved.

For example, in the illustrated embodiment, the inside of the box 45 is divided into two areas as described above, and the two objects A to be sorted are simultaneously moved by the movement of the rollers 49.

Therefore, while the roller 49 advances one pitch, the sorting device 2
The two saucers 9 are made to move forward.

In this case, since the tray 9 of the sorting device and the chain with attachment 2A of the supply device are mechanically connected by the conversion means, the movement timing of both is set with the tray 9 positioned below the tip of the supply device. The object to be sorted A can be dropped from the supply conveyor onto the receiving tray 9.

In the above embodiment, a ratchet machine tm consisting of a pawl 45 and a ratchet wheel 43 was used as the one-way member, but a commercially available one-way clutch may also be used.

In addition, the crank attached to the sprocket and a one-way member such as a ratchet mechanism were connected by a shaft, a lever arm, etc., but the crank lever and the one-way member were connected by a flexible member such as a wire. May be connected. By using wires in this way, connection can be made even in a bent state, increasing the degree of freedom in terms of equipment installation.

However, on the other hand, by using a wire, in preparation for the wire stretching, it is preferable to insert a turnbuckle or the like in the middle to make it possible to adjust the stretching.

In the above embodiment, two objects A to be sorted are supplied by the supply device, but it is also possible to feed objects A to be sorted one by one or three or more objects A to be sorted simultaneously to the sorting device. You can also do this. In this case, the ratio of the number of teeth of the sprockets 3o and 31 is selected as described above, and the timing is set so that the corresponding number of trays 9 are fed while the feeding device is intermittently fed once.

The above-mentioned supply conhair also includes a chain 48 and a roller 4.
9, however, a normal belt conveyor with horizontal bars attached at regular intervals may be used as the supply conveyor.

Another embodiment will now be described with reference to FIG.

Whereas in the embodiments described above, the chains 2A of the sorting device circulated in a horizontal plane, in this embodiment the chains 2A circulate in a substantially vertical plane.

Due to this difference in structure, in this embodiment, one side of the chain drive sub-rot J7-tsut 30 is open to the outside, and the chain 2A is circulated without providing an intermediate sprocket as in the above-mentioned embodiment. The rotation of the line 30 is increased by gears 60 and 61 as appropriate, and the pin 6 is connected to the gear 61.
2 and connect the crank lever 34 with a pin to directly extract the power for intermittent drive. In addition, the gear 60
．． The gear ratio of the gear 61 is appropriately selected so that the supply conveyor advances one pitch while a predetermined number of trays 9 are moved, and the rotation of the gear 61 may be slowed down as necessary. Furthermore, in some cases, the sprocket 30
The bottle 62 may be directly planted in the container.

As described above, in the embodiment shown in FIG. 4, the chain 2A of the sorting device moves in a substantially vertical plane, and is connected to the sprocket 30 around which the converting device or the vertical chain 2A is wound. Crank mechanism 34.62
, and a unidirectional movement member disposed between the crank mechanism and the supply conveyor for transmitting unidirectional movement during reciprocation of the crank mechanism to the supply conveyor.

Furthermore, in this embodiment, the supply device 40 supplies the objects A to be sorted in a direction parallel to the transport direction of the chino 2A of the sorter. Incidentally, similarly to the above-described embodiment, the objects to be sorted may be fed perpendicularly to the chain transport direction of the sorting device. Furthermore, wire 41 is used instead of rod 41.

The configuration of each part is the same as in the embodiment described above, and detailed explanation will be omitted.

Furthermore, instead of providing the intermediate sprocket 31 of the embodiment shown in FIGS. 1 and 2, the sprocket 30 on which the chain 2A is wound is connected via the crank mechanism in the same way as in the embodiment shown in FIG. The supply mechanism may be driven intermittently. That is, in this case, the chain 2A of the sorting device drive system
is adapted to move in a substantially horizontal plane, and a crank mechanism is connected to a sprocket 30 wrapped around the conversion device or the horizontal chain 2A, and a reciprocating motion of the crank mechanism is provided between the crank mechanism and the supply conveyor. It consists of a unidirectional movement member that transmits the unidirectional movement therein to the feed conveyor.

Furthermore, in the embodiment shown in FIG. 4, the intermediate sprocket 3 is similar to the embodiment shown in FIGS.
1 may be provided. That is, the chain 2A of the sorting device
an intermediate sprocket 31 that is adapted to move in a substantially vertical plane, and has a crank mechanism for engaging the vertical chain 2A and converting the unidirectional continuous motion of the vertical chain 2A into reciprocating motion; and a unidirectional movement member that is provided between the crank mechanism and the supply conveyor and transmits unidirectional motion during reciprocating motion to the supply conveyor.
