Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for cutting out a case on a case stacking part such as an article shelf or a pallet in a collection / delivery center or the like for collecting and delivering a box-shaped case containing articles. The present invention relates to a case picking device and method.

[0002]

2. Description of the Related Art In the current distribution industry, generally, goods to be distributed are temporarily collected and stored at a collection / delivery center, and a required number of goods are delivered from the collection / delivery center to an orderer according to an order. ing. In addition, for the convenience of handling and storage in the distribution process, the articles to be distributed are often distributed in the form of being housed in a box-shaped case such as a cardboard box. Then, at the collection and delivery center where the case containing the goods is collected, the collected cases are stored in a predetermined arrangement state in a case stacking part such as an article shelf or a pallet according to the type of the article, and stored according to the order. Picking is performed by cutting out a predetermined number of cases from the case stacking unit.

By the way, in such a collection / delivery center or the like, automation is aimed at in order to improve efficiency and unmanned work of receiving and shipping the case. This automation is a case loading / unloading line such as a conveyor for loading and unloading a case near a designated case loading section, and case picking for automating transfer of cases between the case loading / unloading line and the case loading section. It is realized by combining a system, a control device for controlling the operations of the case loading / unloading line and the case picking system according to the receipt / shipment slip, control software, and the like.

As the case picking system, various types have been proposed so far in which a case picking device for gripping and moving the case is incorporated on a crane or a carriage that can travel along the case loading section. However, depending on the type of case picking device, it can be roughly classified into a suction type and a friction take-out type.

As the suction type case picking device, for example, a vacuum pad for sucking the case is attached to the tip of an arm supported so as to be rotatable or reciprocally movable, and the tip of the arm is to be transferred. Step of moving to the case, step of holding the case by suction with a vacuum pad, step of moving the tip of the arm holding the case to the transfer destination, step of releasing the suction of the case by the vacuum pad at the transfer destination It is well known that the case is moved one by one from the case stacking unit to the case picking device and from the case picking device to the case loading / unloading line by repeating the above sequence.

On the other hand, in the friction pick-up type case picking device, by rotating and driving a roller body whose outer peripheral surface is brought into contact with the front end surface of the case, a case conveyor means such as a conveyor belt interlocking with the roller body is driven. Ride the front edge of the case,
In the following, the case is picked up by the carrying force of the case carrying means and further sent out to the case carrying-in / out line. For example, as in the pick-up table disclosed in JP-A-5-246541, the rollers are There has also been proposed a configuration in which a plurality of transport belts, which are a combination of a body and a case transport means, are arranged in the direction in which the cases are lined up so that a plurality of cases can be collectively transferred.

[0007]

However, in the case of the suction-type case picking device described above, usually, the cases are picked up and transferred one by one, so that an arbitrary number of cases can be cut out (taken out). On the other hand, when the number of cases to be cut out is large, the same cutting work is repeated, resulting in poor processing efficiency.

When the case has a plurality of sizes, the stepped portion on the case (for example, when the case is a corrugated cardboard box, the lid of the box must be adjusted unless the arrangement of the vacuum pads is adjusted for each size of the case. The vacuum pad hits the step due to the overlapping of parts, etc., and it becomes impossible to perform sufficient suction, and the case caught when the arm moves moves,
There was a risk of inconvenience of falling.

Further, recently, a case with a hole is often used to save resources, and there is a problem that such a case cannot be used.

On the other hand, in the case of a friction pick-up type case picking device, as in the pick-up table disclosed in Japanese Patent Laid-Open No. 5-246541, a conveyor belt in which the roller body and the case conveying means are combined is arranged in the direction in which the cases are arranged. By arranging a plurality of cases, it is possible to transfer a plurality of cases at a time, and it is possible to significantly improve the processing efficiency.

However, in the conventional case, even if the conveyor belts are arranged in a plurality of rows so that a plurality of cases can be transferred at once, the conveyor belts in a plurality of rows interlock to perform the same conveying operation. Therefore, if the number of cases such as shipping does not become an integral multiple of the number of cases cut out at once by multiple rows of conveyor belts, a flow rack (fluid It is necessary to equip dedicated equipment such as shelves) around the case picking device or the case loading / unloading line, which causes inconvenience such as complicated structure of equipment for case picking, increase in size, and increase in equipment cost. There was a problem of inviting.

[0012] Therefore, an object of the present invention is to solve the above-mentioned problems, and it is possible to transfer and process a plurality of cases all at once, and not only can the processing efficiency be greatly improved, but also the extra cutting can be performed. Even if you do not have dedicated equipment for temporarily storing cases, you can quickly and reliably transfer the required number of cases, and configure the equipment for case picking. (EN) Provided are a case picking device and method capable of facilitating simplification, size reduction, equipment cost reduction, and the like.

[0013]

The above object of the present invention is a case picking device for cutting out a required number of cases from a group of cases stacked in a plurality of rows, wherein the cases are stacked in a plurality of rows. A plurality of case transfer delivery lines for delivering cases to the stacking section and a plurality of these case transfer delivery lines are supported in a plurality of rows at predetermined intervals corresponding to the case arrangement in the case stacking section. The transport mechanism supporting frame; and a transport line rotating mechanism that is provided between each case transfer transport line and the transport mechanism supporting frame to rotate the case transport transport line on the transport mechanism supporting frame. The delivery / conveyance line is provided with a case conveying means capable of placing a case and delivering the placed case, and the case conveying means. A case which is arranged at an end of the carrying means and has a rotating body for assisting transfer of the case between the case carrying means and the case stacking section, and is not a pickup target case on the case stacking section The case transfer line corresponding to the above is achieved by a case picking device characterized in that the rotating body is retracted by a rotating operation by the transfer line rotating mechanism so that the rotating body does not come into contact with a case other than a pickup target.

Further, in the above-mentioned case picking device, the case transfer means of the case transfer line has a structure in which the transfer belt on which the case is placed is caused to run via a belt drive vehicle, and the transfer belt is also provided. One of the belt cars equipped to drive the
The outer peripheral surface is brought into contact with the front end surface of the case stacked in the case stacking portion, and the front end portion of the case contacted by the forward rotation operation is caused to function as the rotating body for riding on the case transporting means. Depending on the configuration,
The above object can be achieved.

Further, in the above case picking device, the transfer line rotating mechanism applies the rotational force of the drive shaft for driving the case transfer means to the frame of the case transfer transfer line via a clutch device having a built-in brake mechanism. The above object can also be achieved by a configuration in which the case transfer line is rotated by transmitting the signal to the section.

Furthermore, it is a case picking method of cutting out a required number of cases from the case stacking section using any of the above-mentioned case picking devices and sending them to the case shipping line, which corresponds to a case not to be picked up. By rotating the case transfer transport line at the position to be turned by an appropriate amount by the transfer line rotating mechanism, the case transfer line is retracted to a position farther from the case than the case transfer transport line at the position corresponding to the case to be picked up. ,
In that state, the transport mechanism support frame is moved to the case side, the rotating body of the case transfer line corresponding to the case to be picked up is brought into contact with the front end surface of the case, and the rotation of the rotating body causes friction on the case. The front end of the case is raised by the force on the case conveying means, the case is moved onto the case conveying means by the conveying force of the case conveying means, and then the case on the case conveying means is moved onto the case shipping line by sending out by the case conveying means. The above object can also be achieved by a transfer method.

[0017]

According to the above construction of the present invention, the front end portion of the case is also transferred by rotating the rotary body, which is a constituent element of the case delivery / conveyance line, in contact with the front end face of the case for rotation. The case pick-up can be realized by riding on the case conveying means which is a component of the above, and rotationally driving the case conveying means, and so-called friction pick-out type case picking is realized. In that case, since a plurality of case transfer lines for picking cases are provided in a plurality of rows and a plurality of cases can be transferred at the same time, a plurality of cases can be transferred at once.

Moreover, the case transfer lines can be retracted independently of each other in the direction away from the case by the rotating operation, and the case transfer lines at the positions corresponding to the cases other than the pick-up target are previously set. By rotating the transfer line by a proper amount, the transfer line is moved to a position farther from the case than the case transfer line at the position corresponding to the case to be picked up, and then the transfer mechanism is supported in that state. The frame is moved to the case side, the rotating body of the case transfer line corresponding to the case to be picked up is brought into contact with the front end surface of the case, and the front end of the case is moved by the frictional force acting on the case by the rotation of the rotating body. The case carrying means is mounted on the case carrying means, and the case is carried by the carrying force of the case carrying means. To transfer, then, by moving the case on the case feed means from feeding by case conveyor means upper case shipping line, it is possible to transfer only the minimum necessary case reliably and quickly cases shipping line.
