Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for automatically packing fruits and vegetables at a collection and shipping site or a fruit sorting site where fruits and vegetables are boxed, packaged, and shipped.

[Prior Art] Conventionally, as a device for automatically packing fruits and vegetables, the device disclosed in Japanese Patent Publication No. 55-28930 is known.

However, the above-mentioned publicly known endless belt 5
5. A diversion board installed diagonally on the transport path of the conveyor guides the fruit onto the runway (chute) provided on the side of the conveyor in a pressing manner so that it spreads out to the fullest.
A tray pack (hereinafter simply referred to as a pack) is sent out from below to the tip of the chute (runway), and the fruit supplied from the tip of the chute fits into the hole in the pack,
This automatic packing device is used for lemons and citrus fruits that are relatively hard to damage, but it is used for soft fruits such as apples, peaches, and pears that can be damaged just by transferring fruit to fruit. had the disadvantage that it could not be used.

Furthermore, in the above-mentioned known method, the fruits are lined up to the full width of the shoot and are bushed by the succeeding fruits, so the side with few succeeding fruits is not pushed, and only the side with many succeeding fruits is bushed. Therefore, it is not possible to uniformly pack a pack having multiple rows of holes, which has the disadvantage of requiring manual correction.

Especially on the side that is pushed, there are many defects such as the fruit being pushed out between the holes of the pack and riding on it, and the fruit is damaged due to rolling friction at the chain part and the part where the direction is changed by the deflector plate mentioned above. In order to prevent this, it must be corrected in conjunction with the work of removing the oysters by arranging them evenly on the chute, so it does not save labor and is not widely used in Japan, resulting in delays in its practical application.

[Object of the invention] The present invention solves the above-mentioned drawbacks, conveys the packaged articles one by one to predetermined pack hole positions without transferring the packaged articles such as fruits, and reduces the number of holes in the pack. The main object of the present invention is to provide an automatic packaging method and device for packaging articles that can automatically switch supplies accordingly.

In other words, for a wide variety of packs that have different numbers and arrangement patterns of pack holes depending on the item, variety, and size class of fruits and vegetables (hereinafter referred to as goods), the goods discharged from a fruit sorting machine, etc., are transported during transportation. 1 without being transferred or pressured
To provide a method and a device for automatically packing articles into packs for each hole by oscillating the tip of a conveyor that separates and conveys items one by one in accordance with the arrangement of holes in the pack.

[Structure of the Invention] The present invention is applicable to an exit of a device that supplies articles one by one, a sorting and discharging section for each class of a fruit sorting machine, or a device in a pre-process such as a drawer conveyor that conveys articles one by one away from the sorting and discharging section. The automatic packing device installed at the outlet supplied from the container is constructed as follows.

A lightweight and thin sorting conveyor is connected to the outlet of the previous process and swings its tip in the left and right direction using the connecting part as a fulcrum, and the empty packs supplied from the side are placed at the bottom of the sorting conveyor. A pack feeding conveyor is provided that increments in the same direction as the traveling direction.

A delivery conveyor is provided ahead of the pack delivery conveyor to send out the packs containing the packed articles.

The operation of these three conveyors is controlled by a control device incorporating CP and U.

The number of holes in the pack and the arrangement of the holes (pack pattern) are set in advance in the control device, and the operations of the three conveyors are controlled according to the set pattern.

The sorting conveyor is equipped with a sensor (switch) at its tip to confirm the passage of articles, and when it starts, it moves left and right within its swing range and waits at the first hole. The pack feeding conveyor is equipped with a pack detection sensor (switch) at the bottom of the tip of the sorting conveyor to confirm that an empty pack has been supplied, and when the tip of the pack is detected by the pack detection sensor, the pack feeding conveyor is temporarily stopped. At the same time, the belt of the sorting conveyor runs to convey the articles supplied from the previous process.

At the same time as the first article is introduced into the pack No. 16 from the tip of the sorting conveyor, the sorting conveyor swings back to the position of the second hole in response to a signal from the article passage confirmation sensor and waits until the second article is loaded into the pack. At the same time that the articles are thrown into the second hole, they are swung to the position of the third hole, and the same operation is repeated to insert them into each hole in the first row. As soon as the packs are completely loaded into each hole in the first row, the pack feeding conveyor moves forward by an inch to advance the packs by one row (pitch between rows). On the other hand, during this time, the sorting conveyor swings its head to the position of the first hole in the second row and stands by, and at the same time as the article is introduced, it swings its head to the position of the next hole.

The same operation is then repeated to fill each hole in the pack with items in order from the front, and when the last hole has been loaded, the sorting conveyor pauses, and at the same time the pack feed conveyor moves forward and supplies items from the rear. When the next empty pack is detected by the pack detection sensor, the process is temporarily stopped.

Meanwhile, the sorting conveyor stops running and waits until the next empty pack is detected by the pack detection sensor, swiveling to the hole position where the next pack should be placed first. At the same time as the second pack is detected, the sorting conveyor runs to throw in the articles and pack them in the same manner as described above.

Since the sorting conveyor stops running when there are no packs at the bottom of the tip, articles will not fall out of the packs.

There are a wide variety of pack patterns depending on the type of article, standard, etc., but broadly speaking, there are those with an odd number of rows of holes and those with an even number of holes, so two packs are set as one set. That is, in the case of an odd number of columns, No. The first hole of the first column and the end hole of the last column are diagonally on the left and right, so No.
Switching to the position of the first hole in the first row of the 2-pack pack requires a large amount of movement time (this causes a lot of movement time), so the first row of the No. As if it were a beginning.

The pack pattern set in the control device with a built-in CPU is set to 2 packs as a set, so the pack holes are always arranged in an even numbered row, and when the two packs are filled with goods, the sorting conveyor is always at the starting position. Return to position 1
constitutes one cycle.

Of course, if the pack has only an even number of rows of holes, only one pack pattern may be used.Also, if the supply of goods is small and the period between putting in the preceding item and putting in the next item is If there is time for the sorting conveyor to oscillate from one end to the other, only one bank pattern may be set even for odd rows of packs. That is, 1
The sorting conveyor may be returned to the starting position for each pack.

The belt of the sorting conveyor runs after the front end of the pack is detected by the pack detection sensor, and runs continuously until it finishes loading the pack into the final end hole of the last row. Shake the head and put it in each hole one after another and pack it.

The sorting conveyor swings in the left and right directions before conveying the following items, so when packing items that are likely to fall, it is preferable to install side belts on both sides that run at the same speed as the belt. .

If the articles are to be stably conveyed on the belt, it is sufficient to simply provide a side plate.Also, if the sorting conveyor is formed with a V-shaped trough cross section, the articles will be conveyed in the center. Therefore, side belts and side plates can be omitted.

1 empty pack from the side against the pack feeding conveyor
Various means can be used for supplying the particles one by one. In other words, there is a method for manually inserting and feeding packs one by one, a means for feeding packs one by one at the same timing by connecting a belt conveyor to the side of the pack feeding conveyor, and a means for automatically feeding the packs to the side of the pack feeding conveyor. The supply device may be equipped with a means for automatically supplying packs one by one based on a pack supply signal.

The automatic pack feeding device is provided with a magazine case for stacking a large number of empty packs on the side of a pack feeding conveyor, and a slide table for taking out packs one by one from the magazine case and feeding them onto the pack feeding conveyor.

The pack supply signal is sent by a sensor (switch) installed to detect when the preceding pack advances on the pack feeding conveyor and there is space for the slide table to appear, and the slide table is actuated by this signal. and feed empty packs onto the pack feeding conveyor. Instead of the slide table described above, it is possible to use a pusher to push empty packs onto a pack conveyor.

The delivery conveyor has a drive system that moves forward by inching in conjunction with the pack delivery conveyor via a reversible clutch.

It has two drive systems, including a drive system that feeds at high speed independently.
A sensor (switch) is provided to detect the front end of the pack when the goods pack is sent onto the conveyor and the transfer is completed, so that the goods pack that is fed from the sorting conveyor and moves forward in an inch is transferred to the pack feeding conveyor. While the packs are being transferred from the pack to the delivery conveyor, the delivery conveyor increments forward in synchronization with the pack delivery conveyor by interlocking via a reversible clutch. When the rear end of the packed article pack comes off the tip of the pack sending conveyor, the sensor detects this and the single drive motor rotates only the sending conveyor at high speed to send it to the next process. When performing high-speed feeding, the interlocking device incorporates a reversible clutch, so only the sending conveyor rotates at high speed, regardless of the pack feeding conveyor.

This delivery conveyor may or may not be installed in relation to the next process, and is used when automatically packing goods into cardboard boxes, etc., and is omitted when the next process is manual. You can also do that.

The distal end portion 303 of the sorting conveyor 3 is formed on a circular arc along the trajectory drawn when the distal end portion 303 of the sorting conveyor 3 swings in the left-right direction around the center point 2.

The distal end portion 303 of the sorting conveyor 3 is configured to have a thin frame by reducing the diameter of the pulley to minimize the falling distance for throwing the articles into the pack 41, and the belt is driven by the driving of the starting end portion 3011III. A pulley 304 is driven by a small geared motor 305.

The small geared motor 305 for this drive is shown in FIGS. 4 and 5.
As best shown in the figure, the starting end 301 is incorporated into the frame.

A side belt drive shaft 306 provided perpendicularly above one side of the drive pulley 304 is linked via a bevel gear 307, and a side belt drive pulley 308 rotates a side belt 309 at the same speed.

Guide items to prevent them from rolling diagonally to the side.

The swinging mechanism for swinging the sorting conveyor 3 left and right is provided with main body side frames 202 as shown in FIGS. 3 and 6.
An oscillating belt 311 is stretched across the frame of the sorting conveyor 3 between an idler 312 and a drive pulley 313, which are provided, and the oscillating belt 311 is fixed to a part of the distal end portion 303 of the sorting conveyor.

The drive pulley 313 is rotated by a forward/reverse inching drive motor 315 via a belt 314, and the sorting conveyor 3
increments to the left or right.

The swinging belt 311 is provided with detection marks 317 on both sides of the sorting conveyor 3 so that a sensor 316 can detect left and right swinging turning points.

In FIG. 6, the idler 312 is installed in the side frame 202 on the first side, and the bearing installed on the shaft vertically protruding upward from the part 318 is installed, and the bearing installed in the side frame 202 on the other side of the drive pulley 313 is installed in the side frame 202 on the other side. 319 vertical shaft.

A sensor 320 is provided at the tip of the sorting conveyor 3 to confirm that the articles are passing and falling.

The pack feeding conveyor 4 and the sending conveyor 5 are provided within the main body side frame 202 as shown in FIGS. 1 and 2, and the helad pulley 401 of the pack feeding conveyor 4 extends from the tip of the sorting conveyor 3 by approximately the length of one pack. The tail pulley 402 is attached to the sorting conveyor 3.
Install near the fulcrum. The sending conveyor 5 has a length approximately equivalent to one pack 41, and a tail pulley 502 is provided close to the helad pulley 401 of the pack sending conveyor 4.

As shown in FIG. 7, the pack feed conveyor 4 and the feed conveyor 5 are configured such that each helad pulley 401, 501 is combined with an inching drive motor 403, 503 so that each can be driven independently. and the tail pulley 5 of the delivery conveyor 5
02 is interlocked with a belt 405 via a reversible clutch 404, and when the pack feeding conveyor 4 advances by an inch for each row of holes in the packs 41, the sending conveyor 5 is driven forward in synchronization. At this time, the drive motor 503 of the delivery conveyor
is electrically stopped.

On the delivery conveyor 5, when a pack of articles driven and fed from the pack delivery conveyor 4 has finished transferring to the delivery conveyor 5, a sensor 504 detects this and drives a drive motor 503 to send the pack containing articles to the next process at high speed. . When the delivery conveyor 5 performs high-speed feeding, the reversible clutch 404 in the interlocking portion between the tail pulley 502 and the pack delivery conveyor 4 becomes free, and only the delivery conveyor 5 rotates independently of the pack delivery conveyor 4.

The automatic pack feeding device 'f6 is shown in Figures 1 and 8 to 10.
As shown in the figure, it is provided on the side of the driven side of the pack feeding conveyor 4, and a part of the main body side frame 202 is cut out to the height of the top surface of the pack feeding conveyor 4, and the core part is exposed on the pack feeding conveyor 4 from the side. slide table 6
01 is installed in combination with a frame 602, and a magazine case 603 is installed in which many empty packs are stacked on top of the frame.
A pack separating device 604 is attached to the magazine case 603 to support the stacked empty packs 41 from the sides at the bottom, separate them one by one, and supply them onto the slide table 601.

The slide table 601 is connected to a chain 605 that rotates at right angles to the pack conveyor 4 near the tail pulley 402 of the pack conveyor 4 using a connecting fitting 606, and the chain 605 is connected to a small gear motor 60.
7, the slide table 601 forms an ellipse so as to appear and retract above the pack feeding conveyor 4, and preferably, packs are quickly fed while the pack feeding conveyor 4 is stopped.

In FIGS. 8 and 9, the tongue piece 608 shown at the exit of the slide table 601 is used to move the packs 41 supplied from the magazine case 603 to the packs on the table when the slide table 601 returns from the pack feeding conveyor 4 after moving forward. 41, and slides the pack 41 onto the pack feeding conveyor 4 from the slide table 601 that returns below the magazine case 603.

The pack separating device 604 combines a guide 6041 that supports the edge of the pack 41 from the side, a separating claw 6042, and an air cylinder 6043, and separates the stacked packs 41 supported by the guide 6041 using the air cylinder 6043, and causes the claw 6042 to emerge and retract. Then push the pack 41 at the bottom of the pile.

A slide table 601 detects packs 4 from a sensor 406 provided below the tip of the sorting conveyor 3 shown in FIG.
1 is not detected, a pack supply signal is output, the small geared motor 607 is rotated, and the packs 41 are supplied onto the pack feeding conveyor 4.

The pack separating device 604 of the automatic pack feeding device 6 is
When the slide table 601 returns from above the pack feeding conveyor 4 to the lower part of the magazine case 603, the air cylinder 6043 is actuated by the limit switch 609 to confirm the restored position of the table, and only one pack 41 is pushed onto the slide table 601. I'll drop it.

The slide table 601 waits with the dropped pack placed thereon.

To explain in more detail the automatic pack filling device configured as above, when the packs 41 are supplied from the automatic pack supply device 1f6 to the pack feeding conveyor 4, the pack feeding conveyor 4 runs and the holes in the first row of the packs 41 are sorted. When reaching the position facing the tip of the conveyor 3, the pack feeding conveyor 4 is temporarily stopped by a signal from the pack detection sensor 407 that detects the tip of the pack, and at the same time, the sorting conveyor 3 runs to convey the articles and deposit them into the 16th container.

When an article is put in, a signal from a sensor 320 that confirms that the article is falling causes the forward/reverse drive motor 315 to rotate in the forward direction, driving the oscillating belt 311 and directing the tip of the sorting conveyor 3 to the second hole of the pack. Let me come. At this time, the pack feeding conveyor 4 continues to stop, and the sorting conveyor 3 continues to run and throws the next article into the second hole.

Thereafter, this operation is repeated until the packs are loaded into each hole in the first row of the pack pattern stored in advance in a control device (not shown) with a built-in CPU, and when the packs are loaded into the holes at the end of the row, the pack feeding conveyor 4 The drive moves forward and brings the holes in the second row to the front end of the sorting conveyor 3 and stops, while the sorting conveyor 3 continues to run and brings the tip to the first hole position in the second row predetermined by the pack pattern. Drive swing.

The driving forward movement of the pack feeding conveyor 4 and the swinging movement of the sorting conveyor 3 are carried out instantaneously between the time when the previous article is loaded and just before the next article is loaded. For this reason, the articles are fed at intervals.

Thereafter, this operation is repeated, and when the last row of packs is driven forward to the tip of the sorting conveyor 3, the rear end of the packs comes off the sensor 406 and a pack supply signal is output, and the next empty pack is sent from the slide table 601 of the automatic pack supply device 6. It is supplied onto the pack feeding conveyor 4.

This empty pack feeding operation is performed while the sorting conveyor 3 swings the articles to each hole in the last row and the pack feeding conveyor 4 is stopped.

In this way, when the articles have been loaded into the end hole of the last row set in the pack pattern, the pack feeding conveyor 4 moves forward and the sorting conveyor 3 pauses, and the second pack set in the pack pattern is placed in the second pack. The head swings to the first hole position and waits.

When the front end of the next pack is detected by the sensor 407, the pack feeding conveyor 4 stops, and the sorting conveyor 3 resumes its running and starts loading articles. Thereafter, articles are loaded into the second pack in the same manner as the first pack, by loading the articles into each hole of the second pack.

As mentioned above, the sorting conveyor 3 is temporarily stopped between a filled pack and the next empty pack, so items are not dropped into the holes in the pack.Of course, the distance between packs should be kept to a minimum. Needless to say, the position of the automatic pack feeding device and the position of the sensor 406 are set.

As the 2'#th pack is loaded into each row and moves forward, the pack that has been packed first is driven forward and transferred onto the delivery conveyor 5, and when it is transferred onto the delivery conveyor 5, the sensor 504 detects the The front end of the pack is caught, the motor 503 is activated by the signal, and the delivery conveyor 5 rotates at high speed to send the pack to the next process.
Once the puck has passed the sensor 504, the motor 503
stops.

The pack patterns preset in the control device with a built-in CPU are as shown in Figure 11 (A) and (B).
A set of two tray packs with numbers No. 2 and No. 2 is made, and each hole in each pack is placed in the first row, second row, third row, etc. from the front in the direction of travel.
...When the number of columns is odd as shown in Fig. 11 (a), the first hole of the first column of No. 011 and the first hole of the first column of No. 2 are symmetrical in the left-right direction. I will make it happen. That is, No.
, 2 is set to be regarded as the next column (sixth column) after the last column of No., l.

The setting of this pack pattern involves digitalizing and controlling the rotation angle of the motor 315 that operates the oscillation of the sorting conveyor and the motor 403 that drives the pack feeding conveyor forward according to the step size between each hole. It constitutes an electronic circuit.

It is possible to change some of the contents of this application without departing from the technical scope of the invention as described above, and all matters contained in the above description and attached drawings are examples, and do not deviate from the invention. rather than limiting it.

It goes without saying that the content described in the claims can also be applied to devices whose design has been partially changed.

In other words, the structure and oscillation mechanism of the sorting conveyor are changed, the automatic pack feeding device is changed to a different pack feeding means, the combination of the pack feeding conveyor and the delivery conveyor is changed in design, or the delivery conveyor is changed. It is also possible to omit it and change the design to use other means.

[Effects of the Invention] The present invention allows the articles supplied one by one from the outlet of the previous process to be conveyed separately on a belt conveyor without being stagnant, and the tip of the belt conveyor is swung from side to side to separate the articles from each hole in the pack. Since the method is to pack the items one by one, there is a possibility that the items will collide or rub against each other, or that it may be impossible to arrange the items by applying lateral pressure to the items from the outside or pushing and squeezing each other. without causing any damage,
High-grade fruits that previously required careful handling and were packed manually can now be packed automatically.

Furthermore, since the packing process is fully automated, the number of workers is greatly reduced, resulting in a significant labor-saving effect.

In addition, in the past, packing work was also a final visual inspection of the product, but since packing was the main task, visual inspection was neglected and quality control was insufficient.
Since the packing process is automated according to the present invention, visual inspection is carried out exclusively, ensuring thorough quality control and increasing confidence in the market.

Furthermore, since the packs containing the goods that have been filled are intermittently rapidly sent pack by pack on the delivery conveyor, it is also possible to connect an automatic carton box packing device or the like to a subsequent process.
