Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a device for detecting and confirming folded wing pieces to be attached to an automatic box making machine, more specifically, a piece for forming a main body of appropriately shaped cutting paper and a wing piece for sticking are sequentially folded back, and an adhesive is applied to a specific folded wing piece And then attach it to other pieces or blades, and then attach it to an automatic box-making machine that continuously forms folded paper boxes to detect and confirm whether the folded blades are folded correctly. It relates to the device.

[0002]

[Prior art]

 The applicant of the present application has proposed Japanese Patent Application No. 3-96571 as this type of confirmation detection device. The proposal is characterized in that a guide for guiding the paper surface and a sensor for detecting a diagonal flap folded from the paper surface are arranged in parallel, and the step between the paper surface and the diagonal flap is used for detection. It describes the confirmation and detection device for diagonals and flaps in paper boxes.

[0003]

[Problems to be solved by the device]

 However, the sensor that detects the folding back of the flap using the step is to confirm the existence of the flap by touching the upper surface of the folded flap. When doing so, there is a problem that the sensor may come into contact with the adhesive and cause a trouble.

[0004]

[Means for Solving the Problems]

 The present invention is a process in which a material cutting paper cut into an appropriate shape is placed on a manufacturing line, the wing piece of the cutting paper is folded back, and an adhesive is applied to the folded wing piece to adhere it to another wing piece or a main body piece. A folding wing piece detection and confirmation device that is attached to an automatic box making machine that continuously forms a folded paper box, including the A sensor mechanism is provided to detect the presence of the folded winglets in contact with each other to solve such a problem.

[0005]

[Action]

 The device of the present invention flows through the process of sequentially folding back the main body piece of the material cutting paper and the attached wing piece, and after the folded wing piece to be confirmed is folded back on the manufacturing line of the automatic box making machine. It is mounted at a position and comes into contact with the side edge of the folded blade, and the folding process normally operates to detect and confirm that the folded blade is folded. If the folded blade is not folded and the side edge cannot be detected, the control unit connected to the sensor mechanism issues an alarm or stops the box making machine.

【Example】

 Embodiments will be described below with reference to the drawings.

FIG. 1 shows a process of an example of a paper box formed by an automatic box making machine. A material cutting paper A is formed by punching out a suitable shape and pressing a fold line at the time of molding. It is supplied to a production line of an automatic box making machine (not shown) (FIG. 1-), and a step of folding back the main body piece a of the cutting paper A and the attached blade pieces b, c and d, e, and the predetermined folding back. Of applying the adhesive B to the blade pieces d and e of FIG. 1 (FIG. 1-), and then folding back the body pieces f and g and attaching the blade pieces d and b and e and c by the folding back ( 1-), and finally, the folded paper box C is formed by folding back the main body part piece h and sent out (FIG. 1-).

FIG. 2A is a state when the paper box C is being expanded from the folded state, and FIG. 2B is a state in which the expansion is completed and the main body part is folded along each fold line for assembly. It shows the state.

The detection confirmation device of the present invention is installed at the position shown in FIG. 1 during the box making process, and the sensor mechanisms 1a and 1b flow along the manufacturing line as shown in FIG. A guide member 2 for curving the cutting paper A, which is bent downward toward the cutting paper A, and a front base end 3a fixed to the front surface of the guide member 2 with a screw 4 and an intermediate portion 3b are fixed to the guide member 2. Conductive elastic piece 3 formed by bending the wing wing pieces d, e to be detected at a position slightly floating from the lower surface of the bulge in the direction of the side edge and bending the rear free end 3c behind the guide member 2. Is provided, and a conductive detecting portion 5 is provided at the rear end of the guide member 2 with a distance from the elastic knitting 3, and each of the elastic piece 3 and the detecting portion 5 is connected to one of positive and negative electrodes. is doing. In addition, 6 is a support for the sensor mechanisms 1a and 1b, 7 is a hollow mounting shaft for setting the support 6 in a predetermined position, and a communication line to a control unit (not shown) is in the hollow part of the mounting shaft 7. Wiring. Further, 8 is an optical sensor provided on the side surface of the guide member 2 for confirming the existence of the cutting paper A, but the presence of the cutting paper A may be confirmed by other mechanical switch means.

FIGS. 3 to 4 show an operation example of the sensor mechanism 1a. When the cutting paper A passes under the device 1a, the optical sensor 8 first confirms the existence of the cutting paper A and the device stands by. The bulging curved intermediate portion 3b of the elastic piece 3 of the sensor mechanism 1a comes into contact with and is pushed by the side edge of the folded wing piece e having the adhesive B applied to the upper surface after being folded back, and thereby the elastic piece 3 The rear free end 3c touches the detection part 5 and energizes to detect and confirm that the folded wing piece e is correctly folded. If the presence of the folded winglet e is not confirmed for some reason, the control unit issues an alarm or stops the box making machine. The sensor mechanism 1b has the same configuration and operation except that it is symmetrical with the sensor mechanism 1b.

When using high-frequency dielectric instead of a normal electrode, the elastic piece 3 and the detection unit 5 do not necessarily have to be in contact with each other, and detection can be performed only by proximity. It is also possible to detect the proximity of the elastic piece 3 by using a light sensor (not shown) as a detection unit.

Although the embodiment has described one example of the paper box C, the device of the present invention detects the folding back of the wing piece necessary for making the paper box of any shape by freely setting the mounting position and the number thereof. It is something that can be confirmed.

[0013]

As described above, the present invention is provided with the sensor mechanism that detects the presence of the folded-back wing piece by contacting the side edge of the folded-back wing piece. This has the effect of reliably detecting and confirming. Further, even when the adhesive for sticking is applied to the upper surface of the folded wing piece, the effect can be exerted without any trouble.
