Description

[Detailed Description of the Invention] [Industrial field of application] This invention is an open-box torque for measuring the torque required for opening a flatly folded box into a rectangular tube shape. It relates to measuring instruments.

[Conventional technology and its problems]

A box body in which inner flaps are formed at both end edges of a pair of tab plates in a rectangular tubular box body and a lid flap and a bottom flap are provided at both end edges of one side plate of the pair of side plates has been conventionally known.

The box body is normally supplied in a flat-folded state to a paper feed section of an automatic product packing apparatus and opened into a rectangular tube shape before the products are loaded. When opening the box, it is necessary to apply a predetermined torque to the box.

By the way, since the boxes have different strengths of ruled lines and different materials, the torque value required for opening the boxes varies between boxes having the same shape. For this reason, if the flat box body is randomly supplied to the paper feed unit of the automatic boxing device, the box body may not be opened, causing a trouble.

In order to prevent the occurrence of such troubles, it is necessary to perform an inspection to determine whether or not the box is surely opened by the automatic boxing device before the box is fed to the paper feeding unit. .

Generally, in a box forming device, since one lot of boxes is formed under the same conditions, it is considered that the boxes of one lot are opened with the same torque. Therefore, when determining the suitability of a box, it is sufficient to inspect several boxes in one lot.

By the way, conventionally, since there is no inspecting device for discriminating the suitability of the box body, the box body is supplied to the automatic boxing machine without being inspected, which causes a lot of troubles in the boxing machine.

[Purpose of device]

Therefore, this invention solves the above-mentioned inconvenience, and is for an open box that can easily perform an appropriateness determination inspection as to whether or not the box supplied to the automatic box packing device is surely opened by the device. It is intended to provide a torque measuring device.

[Constitution of device]

In order to achieve the above-mentioned object, the present invention is capable of moving a movable jaw, which is also provided with a support portion, with respect to a fixed jaw, which is provided with a support portion of a box body that can be flatly folded and opened in a rectangular tube shape. The movable jaw is connected to a spindle of a pressure gauge, and a moving mechanism for moving the pressure gauge with respect to the fixed jaw is provided.

[Action]

When a flat box body is placed on the support parts of the fixed jaw and the movable jaw and the movable jaw is moved together with the pressure gauge, the flat box body is opened into a rectangular tube shape because both side edges are pushed, and the open box is opened. The torque required for the box is displayed on the pressure gauge.

Therefore, by reading the display of the pressure gauge with the box completely opened and comparing the value with the standard value (standard value), it is possible to determine whether the box is opened by the automatic cartoning device. it can.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the support base 1 has a pair of end plates 3 attached between the ends of a pair of side frames 2, and among the pair of end plates 3,
A plate-shaped fixed jaw 4 is attached to one of the end plates 3, and a plate-shaped support portion 5 projecting on the support base 1 is provided on one surface of the fixed jaw 4.
Is provided.

Further, on the upper surface of the pair of side frames 2 of the support base 1, a long guide groove 6 is provided toward the fixed jaw 4, and a pair of rollers 7 rollable along the guide groove 6 are provided on the support base 1. It is attached to the lower part of the plate-shaped movable jaw 8 arranged at. The movable jaw 8 is provided with a plate-like support portion 9 facing the support portion 5 of the fixed jaw 4, and the box body A folded flat by the support portion 9 and the support portion 5 of the fixed jaw 4. Is supported.

A pressure gauge support plate 10 is arranged behind the movable jaw 8, and a spindle 12 of a pressure gauge 11 supported by the pressure gauge support plate 10 is connected to the movable jaw 8.

The pressure gauge support plate 10 is moved toward the fixed jaw 4 by the operation of the moving mechanism 20. Here, the moving mechanism 20
A nut plate 21 fitted between the pair of side frames 2 is attached to the lower surface of the pressure gauge support plate 10, a nut 22 is fixed to the nut plate 21, and a screw rod 23 screw-engaged with the nut 22 is attached. A handle 2 whose both ends are rotatably supported by the end plates 3 of the support base 1 and whose screw rods 23 are provided at the ends.
The pressure gauge support plate 10 is rotated by rotating at 4.

Now, when the screw rod 23 is rotated by the handle 24 to move the pressure gauge support plate 10, the spindle 12 of the pressure gauge 11 supported by the support plate 10 and the movable jaw 8 are connected to each other. The movable jaw 8 moves together with the pressure gauge support plate 10.

Therefore, the flat folded box body A is supported by the support portion 5 of the fixed jaw 4 and the support portion 9 of the movable jaw 8, and in that state, the movable jaw 8 is directed toward the fixed jaw 4 together with the pressure gauge support plate 10. When moved, the box A is pushed from both sides,
As shown in FIG. 4, the box is opened in a rectangular tube shape, and the torque required to open the box is displayed on the pressure gauge 11.

Therefore, by reading the display of the pressure gauge 11 and comparing the numerical value with a standard value (standard value), it is possible to determine whether or not the box A is an appropriate box that is surely opened by the automatic boxing device. You can

When the box A is completely opened and the movable jaw 8 moves further from that state, the pressure gauge 11 displays the box A
Since the torque required for crushing is displayed, the movable jaw 8 is stopped when the box A is completely opened, and the display of the pressure gauge 11 at that time is read.

Further, the standard value may be a value obtained by averaging the torque required to open a plurality of boxes that can be reliably opened by the automatic boxing device, or the strongest box that can be opened by the above device. It may be the torque required for the box.

In the case of the embodiment, the pressure gauge 11 is rotated by the rotation of the screw rod 23.
The moving mechanism 20 for moving the
0 is not limited to the example.

〔effect〕

As described above, according to the present invention, the box body is supported by the support portion of the fixed jaw and the support portion of the movable jaw, and the pressure gauge having the spindle connected to the movable jaw is moved toward the fixed jaw by a simple operation. The torque required to open the box can be measured. Therefore, by comparing the measured value with the standard value (standard value), it is possible to very easily determine whether or not the box is a proper box to be opened by the automatic boxing device.
