2. Description of the Related Art Conventionally, a picking device that picks articles into a collection container using a cutting method is generally known.

Problems to be Solved by the Invention However, in this kind of picking device, the articles fall into the collecting container, causing serious damage to the articles, and it is difficult to cut out the required number of articles, making it difficult to pick the next article. It is often seen that items are cut out incorrectly, and there are also problems such as items not being placed neatly in the collection container.

Therefore, the purpose of this invention is to solve such conventional problems by picking one or more rectangular parallelepiped, cubic, or similar shaped objects to damage the objects continuously and in a short period of time. To provide a picking device which allows items to be placed in a collection container in line without any problems.

Means for Solving the Problems According to this invention, the picking device includes a conveyor for transporting articles to be picked, a conveyor for conveying collection containers provided to intersect with the conveyor, and articles to be picked. pushing out the articles on the picking article conveyor in a direction perpendicular to the conveyor conveyance direction in order to store the articles from above the picking article conveyor into a collection container transferred by the article collection container conveyor; A pushing device having a pushing bar and a picking cylinder, a pushing plate provided corresponding to the pushing bar and having an elastic force extending downward, and an article to be picked corresponding to a lower portion of the pushing plate, It is equipped with a falling speed control device consisting of a pressure belt sandwiched between the two and a pressure belt for controlling the falling speed.

Accordingly, the picking device of this invention operates a pushing device such as a picking cylinder equipped with a push bar to move the articles to be picked, which are being moved by a conveyor, to a desired position. It is possible to push out the articles, sandwich them between the push plate and the push belt of the falling speed control device, move them downward, and store them in a line in the collection container.

Other objects, features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

Embodiments As shown in FIGS. 1 and 2 of the drawings, the picking device 1 of this invention includes a conveyor 2 for conveying articles A to be picked, and a conveyor for conveying collection containers that intersects with the conveyor 2. 3. A pushing device such as a pneumatic or hydraulic picking cylinder 4 having a pusher bar 5 for pushing out the article A from the conveyor 2 for picking articles, provided corresponding to the pusher bar 5 and extending downward. It mainly includes a falling speed control device 6 consisting of a push plate 7 and a pressure belt 8 corresponding to the lower part of the push plate 7.

In the illustrated embodiment, the articles A to be picked are transported by two rows of conveyors 2 to a stopper 11 for picking articles and are held there.
A conveyor 3 for transporting collection containers is provided to intersect with the transport conveyor 2 in correspondence with this picking article stagnant part, and a picking part is formed in this intersecting part. In this picking section, the conveyor 2
Two pairs of picking cylinders 4 each having a push bar 5 for pushing out the article A from the conveyor 2 are provided on both sides of the conveyor 2 . A push plate 7 of a falling speed control device 6 is arranged between these picking cylinders 4. The push plate 7 consists of two vertical plate members, the upper end of which is supported by a spacer 12 at a distance, the lower end is a free end, and the upper half corresponds to the push bar 5 of the picking cylinder 4. Half corresponds to the pressure belt 8. Therefore, in the illustrated embodiment, up to four articles A can be picked simultaneously by two sets of picking cylinders 4.

A pair of arms 14 extending inward and approximately horizontally are provided at the upper end of a pusher 5 of a pushing device such as a pneumatic or hydraulic picking cylinder 4, and a guide support portion 15 at the tip of these arms 14 is provided.
A stopper 16 for preventing malfunction is provided to be vertically movable. A cam follower or cam follower 17 is provided at the upper end of the stopper 16 and can engage with an inclined cam 19 of a guide plate 18 to move the stopper 16 up and down. Further, on the upstream side edge of the push bar 5, a pair of stop bars 21 for the next picking article A are provided with a space between the upper and lower sides. A guide plate 18 with an inclined cam 19 is provided on the push plate 7 as shown in FIGS.

The pressure belt 8 of the falling speed control device 6 provided on both sides of the push plate 7 is made up of a plurality of pressure belt members 24 hooked on driving and driven shafts 25 and 26, as shown in FIGS. It is designed to hold the article A to be stored in the collection container B by sandwiching the article A between the container and the push plate 7 and sending the article A downward by controlling the falling speed. As shown in the figure, a pair of pressing belts 8 are provided symmetrically, and the driving motor 2
7 drives drive shafts 25, 25, respectively, via appropriate belts, pulleys, and gears. Further, it is preferable that guide bars 30 for preventing the articles A from falling off are provided along both sides of the conveyor 2 for conveying picking articles, as shown in FIG.

In the picking device 1 of this invention constructed in this manner, the articles A to be picked are placed on the conveyor 2 and transported to the picking location, stopped at the stopper 11, and stagnated at the picking location. On the other hand, a large number of collection containers B
were continuously transported by the transport conveyor 3, and when the collection container B arrived at a predetermined picking position, the transport conveyor 3 was not stopped and the goods A were stagnated on the transport conveyor 2. The required number of items are picked by the operation of the picking cylinder 4. Incidentally, if the required number of articles A is not collected when the collection container B comes to the picking position, the conveyor 3 is stopped and the arrival of the articles A is waited. It is preferable to pick the required number of articles A at the same time. Here, the case of picking one article A will be explained.

As shown in FIGS. 3 and 4, the article A held between the push bar 5 of the picking cylinder 4 and the stopper 16 for preventing malfunction is pushed by the push bar 5 and conveyed by the operation of the picking cylinder 4. It moves laterally on the conveyor 2 toward the pushing plate 7 and is pushed from the state shown in FIGS. 4 and 5 to the state shown in FIG. 7. At the time of this pressing, the cam follower 17 engages with the inclined cam 19 of the guide plate 18, and the malfunction prevention stopper 16 is gradually raised by the inclined cam 19 as the article A is pressed and moved, as shown in FIG. When the stopper 16 comes into contact with the push plate 7 as shown in FIG.
and the push plate 7 make good contact engagement. When the push bar 5 of the picking cylinder 4 presses the article A, a stop bar 21 extending laterally from the side edge of the push bar 5 prevents the next article A from moving.

In this way, the article A that has been pushed and moved in the lateral direction from the transport conveyor 2 to the picking position above the falling speed control device 6 is sandwiched between the push plate 7 and the push bar 5 as shown in FIG. When the king cylinder 4 begins to retract, it begins to fall and first reaches the position shown by the dotted line in Fig. 7, and from this point on, the push plate 7 whose upper end is fixedly supported and the lower end is free, and the falling speed. Pressure belt 8 of control device 6
While the falling speed is controlled by the following steps, it descends as shown in FIGS. 8 and 9, passes through the falling speed control device 6, and then falls into the collection container B. When this article A falls, the push plate 7, which is supported at the upper end and whose lower end is free, can bend inward, so that the article A
is pushed downward at a speed corresponding to the drive speed of the pressure belt 8 with the help of the suitable elastic force of the push plate 7, and descends between the push plate 7 and the pressure belt 8 at a controlled falling speed. It passes through the falling speed control device 6 and is suitably stored in the collection container A. That is, the article A is the article A as shown in FIG.
Since the item A is placed into the collection container B with a falling distance between the bottom surface of the container B and the inner surface of the lower part of the collection container B, it is essentially the same as placing the item A into the collection container B by hand. It can be placed quietly and softly, there is no damage to the item A due to impact, and there is nothing in the way other than the item, such as a gripping hand, in the collection container B, so picking can be done in a short time. It is possible to finish the process and arrange the items in the correct position.

Also, from the state shown in Fig. 7, the picking cylinder 4
When retracting, the malfunction prevention stopper 16 is raised sufficiently upward, so that it does not pinch the article A and helps the article A fall smoothly.
Also, at this time, the malfunction prevention stopper 16, which had been raised by the inclined cam 19 of the guide plate 18 via the cam follower 17, gradually descends as the picking cylinder 4 is retracted, and the picking cylinder 4 is completely removed. When the next article A is drawn in, the conveyor 2 smoothly feeds the next article A between the push bar 5 of the picking cylinder 4 and the malfunction prevention stopper 16, and the article A is pushed out when the adjacent picking cylinder operates. This prevents them from being accidentally extruded together.

Picking of such articles A is carried out one by one, or one or two sets of left and right picking cylinders 4 are used simultaneously or individually in a desired combination to pick articles A into the collection container B. By repeating this, it is possible to carry out the specified picking process properly, and the articles A can be stored neatly and accurately in the collection container B, and then the picking of the articles A can be carried out in the next collection container B in order. It can be repeated continuously. It should be noted that the present invention can also be applied to cylindrical articles by forming the pressing surfaces of the push bar, the pressing plate, and the pressing belt into a concave shape.

Effects of the invention In this way, according to the picking device of this invention,
It is possible to pick a required number of rectangular parallelepiped, cubic, or similar shapes one by one or to pick multiple items at the same time and store them in a line in a collection container, and the falling speed of the objects can be controlled via a falling speed control device. It is possible to control the items so that they fall quietly into the collection container without damaging them in any way, and the picking can be carried out continuously and without taking into account the time for hand members other than the items to enter and leave the collection container. It is possible to achieve effects such as being able to complete the process in a short time and efficiently without wasting time.
