Description

The present invention relates to an automatic unpacking cutting method for a corrugated cardboard case and an automatic tray making system in a bulk shipping distribution system.

In the current distribution in the bulk shipment distribution system of the present invention, the cardboard boxes containing the products are collected at the distribution center, the cardboard boxes are unpacked, the internal products are taken out, and the products are transported to the automated warehouse for management. There are many methods. In the automated warehouse, considering the convenience of transporting trays to storage species, single or multiple products are stored in a dedicated tray and stored on shelves. This has the advantage of increasing storage efficiency and speeding up the loading and unloading of trays. In particular, when performing robot picking in an automated warehouse for online logistics, it is safe to think that a standard tray is indispensable.

In many cases, when a product is taken out from a cardboard box, a worker manually unpacks the cardboard box and puts the product in a tray. The cardboard box is usually closed by sticking the abutting part of the two outer flaps and the side surface connected to it with adhesive tape such as gum tape, and the worker cuts the adhesive tape part with a cutter etc. and takes out the product. ..

The unpacking work of the cardboard box can also be unpacked by an automatic device. As in Patent Document 1, there is a device for incising the adhesive tape of the outer flap on the upper surface of a cardboard box and unpacking it by a mechanism for opening the outer flap and the inner flap.

However, the automatic unpacking device of Patent Document 1 only opens the outer flap and the inner flap on the upper surface, and the subsequent work of taking out the product or transferring it to the tray is performed manually by a worker or by a worker. It is necessary to take it out by an automatic device such as robot picking and transfer it to the tray.

At present, products are often transferred to trays by workers, and even if the automatic unpacking device of Patent Document 1 is used, only one process of cutter incision, which is the unpacking work procedure, is reduced by the worker. Therefore, it is necessary for the worker to take out the product and transfer it to the tray.

Therefore, the inventor automatically unpacks the cardboard box containing the product and puts it in the tray in order to eliminate the need for the product of Patent Document 1 and the worker who is currently working on the product and transfer it to the tray. Patent Document 2 has proposed a cardboard box unpacking system for this purpose.

The cardboard box unpacking system proposed by the inventor according to Patent Document 2 is a system for unpacking a cardboard box in which the abutting portion of the outer flap is bonded with an adhesive tape and transferring the stored product to a tray. A cutter device for incising the adhesive tape at the bottom of the cardboard box, a bottom opening device for opening the flap outside the bottom of the cardboard box, and a tray transporting device for transporting a tray directly under the bottom opening device. The adhesive tape on the bottom surface of the cardboard box conveyed by the conveyor is cut open by the cutter device, the cut cardboard box is set in the bottom opening device, and the bottom surface is opened by the tray transport device. The tray is conveyed directly under the device, and the products in the cardboard box are dropped onto the tray by opening the two outer bottom flaps of the cardboard box with the bottom cut open by the bottom opening device. The opening device includes an arm that grips the side surface of the cardboard box, an air gripper in which an air-driven sucker attracts the outer flap on the bottom surface and rotates the outer flap around the ridge, and the cardboard box is moved up and down to open. It is a cardboard box unpacking system characterized by being provided with an elevating mechanism that raises and lowers a constant distance between the lower end of the cardboard box and the tray.

Further, the inventor is proposing an unpacking cutter of Patent Documents 3 and 4.

The unpacking cutter according to Patent Document 3 has a cutter holding portion 43 provided with a through hole 46 and notches 47a and 47b for adjusting the cutting edge on both wings of a mountain-shaped ruler 42 that slides in contact with the outer surface of a corner of a packing body. In the unpacking cutter 40 provided so that the cutter holding body 45 can be inserted and removed from the holding portion 43, a retaining means 70 for holding the holding body 45 is provided between the holding portion 43 and the holding body 45. Specifically, the retaining body 45's retaining means 70 slidably disposes a bar between the holding portion 43 and the pinching body 45, and the bar is placed. It can be operated by a knob 72 provided on the outer surface of the holding portion 43.

Further, the unpacking cutter according to Patent Document 4 has a mountain-shaped ruler 12 that abuts on the outer surface of a corner of a packing body and slides, and a cutter that allows the cutter 18 to be attached to and replaced with the mountain-shaped ruler 12, and the cutter to which the cutter 18 is attached. The cutting edge of the cutter 18 is composed of a support portion of the cutter 18 so that the cutting edge of the cutter 18 protrudes toward the inner peripheral edge of the corner of the packing body, and if necessary, the cutting edge of the cutter 18 is a recess formed inside the corner of the packing body. Protruding toward 21, the accommodating portion 24 of the spare cutter 23 is provided at one end of the mountain-shaped ruler 12, and the handle 25 is provided on the mountain-shaped ruler 12.

However, with the technique disclosed in the above patent document, it is difficult to accurately measure the size of the corrugated cardboard case on the conveyor in millimeters. As a result, the position where the rotary blade enters is displaced, the blade cannot be inserted into the proper position (within a corner of 5 mm), and the rate of cases where automatic cutting is possible is low.

Then, in the bulk shipping distribution, the work of opening the corrugated cardboard case is required, and these work is automated. Normally, the adhesive tape in the center of the case is cut and opened, but the four lids opened during picking get in the way and hinder the picking work, so it is necessary to cut the four open lids. Become.

In addition, if picking is to be performed by an automated warehouse or a robot, it is necessary to replace the products in the case with a standard-sized plastic container having good storage efficiency. The work of holding a cutter, opening the cardboard, and cutting the ears of the lid is low in productivity, and above all, accidents caused by the cutter are endless. At distribution sites with small quantities and a wide variety of products, it is necessary to process a huge number of cases every day, and there are high needs for labor saving, automation, and safety.

Traditionally, there are several manual and automatic cutting methods for cardboard cases.
In both cases, the top surface angle of the corrugated cardboard was 45 degrees, and the method was to cut with a cutter blade or a rotary blade.

However, the above-mentioned automatic cutting system is a method of automatically measuring the vertical and horizontal sizes of corrugated cardboard and aligning the rotary blades with both corners of the case. The position where the rotary blade enters is within 5 mm from the corner so as not to damage the product, which makes positioning difficult.

The height and width of the corrugated cardboard are measured at the position where the phototube passes on the conveyor, but if the tip of the corrugated cardboard is deformed, the cut may be deep or shallow, and it may not be possible to cut well.

The rotary blade is also made thin to reduce the resistance of the cut. A thin blade has good sharpness, but it often happens that the blade is distorted due to the thickness and hardness of the corrugated cardboard and cannot be cut horizontally. Further, by cutting the gum tape portion of the corrugated cardboard, the glue adheres to the rotary blade, and the blade needs to be cleaned or replaced.

The present invention is for solving the above-mentioned problem, and first, it is a method which does not need to measure the size of a case on a conveyor. It is a shift from the method of cutting the upper surface of the case to the method of cutting the lower surface of the case. When the case is moved to the side on the conveyor, it can be automatically positioned without measuring the bottom angle of the case.

The method of cutting the square surface of the cardboard case with a round blade is changed to cutting with a circular saw or an electric plane. When cutting with a blade, if you want to improve the cutting method, you need to make the blade thin and sharp, and as a result, the blade loses to the deformation of corrugated cardboard and cannot be cut straight. By cutting and cutting, the blade naturally becomes thicker and stronger. With a circular saw, the blade thickness increases from 1.5 mm to 2 mm, and corrugated cardboard can be easily cut at high speeds.

To cut the bottom corner of the corrugated cardboard, first move one side to the side on the conveyor, cut the bottom surface, and then guide the rollers of the conveyor in the opposite direction to cut the opposite bottom corner of the corrugated cardboard. The remaining two bottom corners can be cut by advancing on the conveyor and converting at a right angle.

Laminated automated warehouse storage is more efficient for product storage. Rather than storing cardboard in various sizes, storing it in a standard plastic container is faster in taking in and out, more efficient in storage, easier to pick, and eliminates the work of processing empty cardboard. Productivity is also high. Especially in the case of robot picking, picking from a standard plastic container is faster than picking directly from a cardboard, and the image judgment and the operation of taking out the product with the robot arm are faster, and the standard container is more efficient.

When putting it in a standard container, the work of transferring the product is required from the cardboard case. Currently, there is only manual transfer work. These automations are also possible by combining the above-mentioned bottom automatic cutting with a robot.
If the bottom corner of the cardboard case is cut at 3 corners instead of 4 corners, the top surface is sucked up and lifted by a robot, and the product is transferred onto a standard container, the product will be dropped and transferred to the container by gravity.

Therefore, the method for automatically unpacking and cutting the corrugated cardboard case in the bulk shipping distribution system of the present invention is the method for automatically unpacking and cutting the corrugated cardboard case in the bulk shipping distribution system, and the corrugated cardboard case is used in the transport process of the corrugated cardboard case. Each part of the bottom surface and the peripheral side surface of the corrugated cardboard is cut and opened along the corner direction, and the bottom surface of the corrugated cardboard case is unpacked and cut so that the bottom surface of the corrugated cardboard case can be unpacked through the cut opening of the corner portion. It is characterized by being configured by.

Further, in the automatic traying system in the bulk shipping distribution system of the present invention, in the transporting process of the corrugated cardboard case in which the bulk shipping products are packed, at least three corners of the bottom surface and the corners of the peripheral side surface of the corrugated cardboard case. In the process of cutting and opening the corrugated cardboard through an automatic cutting means using a round saw blade or a flat saw blade and the transfer process of a predetermined standard container, the corrugated cardboard case after the cut opening process is placed at the stop position in the transfer process by the robot. The process of unpacking the bottom of the cardboard case by sucking it onto the standard container via an arm and pulling it upward, and transferring the loosely shipped products in the cardboard case into the standard container, and in the cardboard case. It is characterized in that it is composed of a process of transferring an empty corrugated cardboard case after being transferred into a standard container into a standard container and driving and transferring the empty corrugated cardboard case to a broken material conveyor via the robot arm.

According to the present invention, the work of opening the corrugated cardboard case and removing the lid, which occurs in the physical distribution of roses, is automated, and labor saving and cost reduction are possible.

Then, the products in the cardboard case can be automatically transferred to the standard plastic container stored in the automated warehouse by a robot.
