Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention stores an aluminum foil or a synthetic resin film,
The present invention relates to a device for joining a metal blade and a carton of a box having a metal blade so that the metal blade can be pulled out and cut appropriately.

[Conventional technology]

Conventionally, as shown in FIG. 3, a metal edger device 1
Conveys the carton A between the upper member 3 and the lower member 4 by the conveyor belt 2, abuts the carton A against the protruding stopper 5, and holds the upper member 3 and the lower member 4 to load the carton A. On the other hand, the metal strip-shaped member 6 is supplied to the lower side of the loaded carton A, and the metal strip-shaped member 6 is cut to a predetermined length by the lower blade 7 and the upper blade 8 of the lower member 4, and this cutting is performed. The metal blade formed by is joined to the carton A by the rise of the upper blade 8, and the carton A with the metal blade is released from the upper member 3 and the lower member 4 and is sent to the discharge table 9. ing.

In the carton, the joining position of the metal blade B is different between the carton of the box for storing the aluminum foil (see FIG. 4) and the carton of the box for storing the synthetic resin film (see FIG. 5). Is changed, that is, the carton position with respect to the upper blade is changed.

[Problems to be Solved by the Invention]

However, conventionally, after carrying out the alignment of the carton on the carton transfer line, the carton is sent out in the direction orthogonal to the transfer line and loaded into the device, so when the carton is sent to the device. There is a possibility that this carton may be displaced and easily fixed in that state, that is, a defective product may be produced in which the metal blade is joined to the carton in a displaced state. For this reason, it is necessary for the worker to directly inspect each carton with a metal blade that is sequentially discharged.

Therefore, it has been an issue to make it easy to find defective products.

[Means for Solving the Problems]

The present invention has been made in consideration of the above problems, and after joining metal blades formed by cutting a metal strip-shaped member to predetermined positions of respective cartons that sequentially abut against a supply stopper and stop, the carton with the metal blades is joined. In a metal edger machine that discharges, the carton detection means that detects the presence or absence of a carton that has abutted against a stopper and the carton that abuts and stops at a stopper correspond to two locations along a preset proper rear end position. Rear end detection means for detecting the presence or absence of the abutting stopped carton at the proper rear end position, and an arrangement state of the abutting stopped carton based on the detection result of the carton rear end detection means. A metal edger machine is provided which is provided with a display means for determining whether the quality is good or bad to solve the above problems. A.

[Work]

In the present invention, the carton supply detecting means detects whether or not there is a carton that stops by abutting against the stopper, and the carton rear end detecting means detects whether or not the rear end of the carton that has stopped abutting is at an appropriate position. Then, in the detection result of the carton rear end detection means, for example, when it is detected that at least one of the rear ends is present, the display means displays that the carton is displaced, and when the rear end is detected as absent, The display means displays that the cartons are properly arranged, and indicates to the operator, for example, whether the ejected cartons with metal blades are defective.

〔Example〕

Next, the present invention will be described in detail based on an embodiment shown in FIGS. 1 and 2. The parts having the same configurations as those of the conventional example are denoted by the same reference numerals and the description thereof will be omitted.

That is, according to the present invention, the carton detecting means 10 including a spot sensor or the like having the sensor spot 10a set in the proper stop region of the carton A which is stopped by the stopper 5 on the supply port side of the carton is arranged and preset. A carton rear end detection means 11 including a CCD sensor or a reflective or transmissive sensor having two sensor spots 11a is disposed near the proper rear end position of the carton and outside the proper stop region. Then, the carton detecting means 10 and the carton rear end detecting means 11 are connected to the control unit 12, and when the carton is supplied and abutted and stopped, the carton detecting means 10 detects that there is a carton. The control unit 12 operates the carton rear end detection means 11 to detect whether or not there is a carton at the sensor spot 11a.

In the sensor spot 11a of the carton rear end detection device 11, when at least one carton rear end is located,
This means that the carton A is arranged in a shifted state, the carton rear end detection means 11 detects that there is a carton, and the information is sent to the control unit 12. If the carton A does not cover the sensor spot 11a, this means that the carton is located at the proper position, and the carton trailing edge detection means 11 sends the information to the control unit 12 as no carton.

In the control unit 12, the display means 13 is connected,
When the carton shift is detected by the carton trailing edge detection means 11 and when the carton shift is not detected (that is,
A display corresponding to each case (when the carton is properly arranged) is provided by the display unit 13 by the control unit 12. For example, together with the discharge tamming of a carton with a metal blade, it is possible to express the quality of the discharged product by a lamp lighting display or the like so that a worker or the like can identify. In addition, when defective products are discharged, it is also possible to implement an operation of stopping the device body or the discharge-side device so that the defective products can be removed.

Reference numeral 20 in the drawing denotes a roller for pressing the supplied carton A from the rear end side toward the stopper side.

〔The invention's effect〕

As described above, according to the present invention, the metal edger machine, after joining the metal blade formed by cutting the metal strip-shaped member to each predetermined position of each carton that is sequentially supplied and abuts against the stopper, In a metal edger machine that discharges this carton with a metal blade, a carton detection means that detects the presence or absence of a carton that has abutted against a stopper and a carton that abuts against a stopper and is stopped along a preset proper rear end position Carton rear end detecting means arranged corresponding to two positions and detecting the presence or absence of the carton stopped at the appropriate rear end position, and stop abutting based on the detection result of the carton rear end detecting means. Since it is equipped with a display means for judging and displaying the quality of the disposition of the carton, the carton with the metal blade can be directly seen by the operator. Detecting defective products without inspection, making inspection work extremely easy and eliminating the inclusion of defective products in discharged carton carts with metal blades. Is.
