Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a method for dividing folded boxes such as pasted milk cartons (hereinafter referred to as folded boxes) into a predetermined number of boxes when packing them into a cardboard box. The classification of folding boxes for carrying out is related to the method and equipment installed and used in the delivery of box-making machines.

[Conventional technology]

Currently, in order to form the folded boxes flowing from the box making machine into a fixed number of bundles, the Il box machine is equipped with a counting device that operates in conjunction with a device that pulls out one folded box laterally. These two devices generate folding boxes that move laterally at intervals of a fixed number of sheets, which are separated manually to form a bundle of a fixed number of sheets.

Furthermore, as devices for automatically forming small bundles, there are known Japanese Patent Application Laid-Open No. 111868/1986 "Folding Box Bundle Forming Device" and Japanese Patent Application Laid-open No. 56-32212 "Folded Box Packaging Device". ing.

[Problem to be solved by the invention]

In the manual method of forming small bundles as described above, since the folding boxes are separated manually, the folding boxes may be damaged by hand, and handling of the bundles of folding boxes requires skill, so it is difficult to increase the production speed as desired. Therefore, it was not possible to automate the delivery work of the box making machine.

Additionally, Japanese Patent Application Laid-Open No. 62-111868 [Folding box bundle forming device] and Japanese Patent Application Laid-open No. 56-32212 “Folded box packaging device” are devices for automatically forming small bundles.
However, since the equipment is complex and requires a large installation space, it is difficult to install it in existing equipment. To obtain a method and device that can be easily sorted by using a counting device and a batting device that makes folding boxes protrude sideways after a certain number of sheets, and that can be easily installed in existing equipment. When the sensor detects the protruding folded boxes that move to the side every predetermined number of sheets using the counter and batting device installed in the box making machine, the folded boxes that are protruding and move to the side are hooked with a skewer. Then, a skewer is inserted into the gap to form a predetermined number of small bundles, thereby sorting the pieces.

[Effect]

In the present invention, as described above, a folding box that has been moved and protruded to the side is detected, and a skewer is inserted in the west and east directions of the folding box along the front surface of the folding box, thereby dividing the folding box into sections every predetermined number of folding boxes. When one sorting is completed, the skewer is retracted and the next protruding folding box is inserted again, thereby being sorted.

〔Example〕

Fig. 7 shows a transport device for a folded carton (folding box) 1, which is installed following a known box making machine, with (a) being a top view and (b) being a front view. It is a diagram. The cartons 1 are transferred while being sandwiched between the transfer belts 2.3, and are counted by a counting sensor 4 provided along the way, and every predetermined number of cartons are counted by a batting device s! 5 causes the corresponding cartons to fly out to the side, and in this state the group of cartons is conveyed to the apparatus by a press conveyor 6.

As shown in FIG. 8, the cartons conveyed in this manner are arranged in a sashimi-like manner on the delivery conveyor 7, and the carton at the leading position is raised by a carton raising skewer 8 tilted in the direction of travel. It is supported by a support skewer 9, and is guided so that the transport conveyor 10 is decelerated more than the delivery conveyor to compress the flow of cartons and come into an upright state. If this operation of the carton raising skewer 8 is performed first after the cartons are transferred, then the alignment of the cartons will continue naturally.

1st Embodiment> FIG. 1 is a top view of the device according to the first embodiment of the present invention, and FIG. 2 is a front view of the same, in which the device is moved by a conveyor while being supported in a substantially upright state by a front support skewer 9. A sensor 11 is provided for detecting cartons 1a that are thrown out in the horizontal direction every predetermined number of cartons in a group of cartons, and an air cylinder 12a is installed at a subsequent position along the front surface of the popped out cartons 1a.
A skewer 12 is provided for the section to be taken in and out.

As mentioned above, if the counting sensor 4 and the batting device 5 attached to the box making machine detect the cartons 1a that have protruded to the side every predetermined number of sheets, and the protruding carton detection sensor 11 has detected the cartons 1a, the cartons are sorted into skewers. 12 is pushed out along the front surface of the carton 1a by the actuator 12a. At this time, the section with a circumference of 12 should not be inserted perpendicularly to the flow of the carton group, but should be inserted into the carton bundle with a slight inclination opposite to the direction of movement, along with the protruding carton 1a, as shown in the figure. good. In this way, the tip of the section with a circumference of 12 collides with the protruding front surface of the carton 1a and displaces the carton 1a diagonally, creating a gap between it and the preceding carton, and the section keeps the circumference of 12 in place. Can be inserted accurately. In this manner, once the circumference 12 has been inserted into the section, the speed of the conveyor belt 10 is increased to separate the carton bundle from the rear carton bundle, and the section retracts the circumference 12. At this time, by providing a front support skewer 9 and a conveyance rear presser skewer that supports the rear of the separated carton bundle, the carton bundle can be transported while standing side by side. Incidentally, if the carton bundle is to be transferred in a fallen state, the front cover skewer 9 can be retracted.

Second Embodiment> FIG. 3 is a top view of the device according to the second embodiment of the present invention, FIG. 4 is a front view of the same, and FIGS. 5 and 6 are top views and FIGS. Front view.

Then, a carton contact area 13 is arranged to collide with the cartons 1a that are laterally thrown out every predetermined number of cartons in a group of cartons that are supported in a substantially upright manner by the front support skewer 9 and are moved by the conveyor. A sensor 15 is provided to detect the timing of the collision with the carton 1a, and based on the collision timing detection signal, a segment with a circumference of 12 is inserted into the gap 14 by the actuator 12a (fifth to sixth (See Figures ■～■). In addition,
As this sensor 15, appropriate sensors such as detecting the collision pressure between the carton 1a and the carton contact area ratio 13, activation of a limit switch due to the collision, detection of the carton 1a popping out, detection of the gap 14 caused by the collision, etc. are used. can be used.

Next, the carton pressing circumference 13 is removed, and the rear pressing skewer 16 attached to the dividing circumference 12 is sent forward (in the transport direction) by the actuator 16a to separate the carton bundle. In this division, the rear surface of the separated carton bundle is in contact with a conveyance rear presser skewer 17 attached to the carton bundle conveyor 10, and the front surface of the rear divided cartons is supported by another front support skewer 18. Do as you please.

The division is from the carton bundle with a circumference of 12 to the actuator 12a.
Pull it out and return it to its initial state (see Figures 5 and 6).

The pop-up carton 1a can be sorted by using the movement when inserting the circumference of 12 to retract the protruding part, or by using another method to make it flush with other cartons so that it can be used for the next box. Make it easy to handle with packing equipment.

〔Effect of the invention〕

According to the present invention, a predetermined number of cartons are popped out sideways by a carton counting device and a batting device provided following a box making machine, and each popped-out carton is divided along its front surface. By inserting a protrusion, it is possible to reliably separate carton bundles, so by simply adding a simple device to the conventional device, it is possible to automate the sorting of carton bundles, and by attaching a cartoning device to the rear. It becomes possible to perform everything from box manufacturing to box packing work unattended.

Also, if you do the classification manually like in the past.

Inevitably, there would be errors in sorting the front and back of the pop-up cartons, making it impossible to form accurate small bundles, and it would not be possible to prevent losses if too many were delivered or complaints from customers if too few were delivered, but the present invention According to the above, there is no need to worry about such a situation occurring, and moreover, it is possible to cope with this situation even if the production speed of the box making machine is increased.

In the above embodiment, a carton was treated as an object, but it is not necessarily limited to only a carton, and can also be used for cards, envelopes, etc.
