Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a box strapping machine,
More specifically, the present invention relates to a box strapping machine suitable for hanging a strap on a box, particularly a folded lunch box.

[0002]

2. Description of the Related Art Heretofore, when transporting a box, the box is tied to the box in order to increase the transport efficiency or to prevent scattering due to spillage of a stored object. And
Various tying machines have been proposed and implemented in order to save labor in the tying operation. One of the binding machines uses a rotary strap arm. That is, as shown in FIGS. 5 and 6, the binding machine 1 includes a pulley 8 attached to an electric motor 6 and a horizontal shaft 7 in a main body 5 including a front frame 2, a rear frame 3, and a cover 4. A second gear 11 supported by the gear 9 and the shaft 10 and meshing with the first gear 9
And a third gear 13 meshing with the rotary gear 12 and the second gear 11.
A shaft 15 through which the string 14 is inserted and a tying device 16 attached to the shaft 10 are arranged.
And the front frame 2
One outer table 17b constituting the table 17 above
Are fixedly arranged so as to have an interval with the inner table 17a.

[0003] In such a configuration, when the box A, which is a tied body, is placed on the table 17 and the electric motor 6 is operated, the rotation of the box A via the V-belt 19 causes the pulley 8 to rotate.
Since the power is transmitted to the first gear 9, the second gear 11, and the third gear 13, the cord arm 12 is rotated.
At this time, since the tip of the string 14 is gripped by the knotting device 16 in advance, the string 14 can be wound around the box A. Thereafter, the string 14 is tied and cut by the knotting device 16.

[0004]

However, there is a problem with the conventional box strapping machine as described above. That is,
When the box A is, for example, a folded lunch box, food and the like are accommodated in the main body, and a lid is put on the main body, and then the strap is hooked. As a result, the knot of the string is connected to the back side of the box A. Become. For this reason, when trying to open the box A, it is not only inconvenient, but also there is a risk that stored items such as food may fall and be scattered.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a table on which a box is placed and a table arranged on the side of the table. A rotary tying arm, and a tying device for tying and cutting the lace wound around the box by the rotary tying arm, and arranging the tying device on the table so as to have a predetermined interval. It is intended to provide a lacing machine for a box. And, preferably, the interval between the knotting device and the table is configured to be adjustable. The interval between the knotting device and the table can be performed by raising or lowering one of the knotting device and the table.
It is preferable that the tying device is fixed and only the table is raised and lowered.

[0006]

According to the strapping machine for a box with such a configuration, the box can be placed on the table and the string can be tied on the upper surface of the box, so that the box can be opened easily and easily. In addition to the above, there is no danger of falling, for example, spilling out of the container such as food. In addition, by adjusting the distance between the knotting device and the table, not only is the work of placing the box on the table easy, but also it is possible to tie the box to various boxes having different depths. Further, by adjusting the distance between the upper surface of the table and the tying device by raising and lowering the table, the distance can be adjusted with a simple structure and with good operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a strapping machine for a box according to the present invention will be described below with reference to FIGS. In these figures, the same reference numerals as those in FIGS. 5 and 6 denote the same names. Attaching members 22, 23 for attaching guide bars 20a to 20d and an elevating drive device 21 such as an electric cylinder are fixed inside the front frame 2 constituting the binding machine 1, and the guide bars 20a to 20d and the elevating drive device are fixed. 2
1 is provided with a table 24. Therefore, by operating the lifting drive device 21, the table 24
Is raised or lowered while maintaining the horizontal state, so that the distance L1 between the upper surface 24a and the knotting device 25 described later can be adjusted. As shown in FIG. 3, the table 24 is provided with an interval L2 between the outer table 24b and the inner table 24c.
And is connected by a connecting member 26 which is bent so as to have. The strap arm 27 is connected to the connecting member 2.
In order to be able to rotate in the space 6, the space L3 is configured to have an interval L3 larger than the rotation diameter of the strap arm 27, and the string 14 hung on the box A passes through the interval L2. The strap arm 27 includes a tubular horizontal arm 27a and a mounting arm 27b. The mounting arm 27b is mounted on the inner surface of the ring gear 28. The ring gear 28 includes a flanged idler 29.
a and 29b and a driving gear 30 rotatably supported on the inner surface of the rear frame 3. The drive shaft 33 supported by the rear frame 3 and the bracket 32 attached to the tip of the horizontal member 31 has a tying device 25 and a drive gear 34.
The drive gear 34 is engaged with the idler 29a. Reference numeral 35 denotes a string guide attached to the rear frame 3, and the string 1 placed in the string stock 36.
4 is supplied from the string guide 36 to the tying device 25 via the horizontal arm 27a constituting the string hanging arm 27. The knotting device 25 has a known structure having a crow's mouth and the like, and has a function of gripping, knotting and cutting the string 14. 37 is the second gear 11,
38 is a shaft for supporting the drive gear 30 and 39 is a shaft for supporting the idler 29a.

In the box lacing machine having such a configuration, the box A is now placed on the table 24, and the lifting drive 21 is first operated so that the upper surface of the box A is tied by the tying device 25. Make sure it is in a possible position. Then, when the electric motor 6 is operated, the rotation is transmitted to the pulley 8, the driving gear 27, and the ring gear 30 via the V-belt 18, and the cord hanging arm 27 is rotated to wind the cord 14 around the box A. . At this time, the idler 29a and the driving gear 34 tying device 25 operate after a predetermined time has elapsed, specifically, after the string 14 is wound around the box A, to tie and cut the string 14.

Of course, the present invention is not limited to the above embodiment. An important point of the present invention is that the tying device 25 is provided so as to have a predetermined interval on the table 24 on which the box A is placed.
And a knot is formed on the upper surface of the box A by the knotting device 25. Therefore, it is apparent that various modifications can be made without departing from the above concept.

As is apparent from the above description, according to the box tying machine of the present invention, the knot is tied to the box and the knot is formed by the knotting device arranged on the table. This knot serves as the upper surface of the box, and as a result, when the box is to be opened, not only can it be easily and easily opened, but also there is no danger that the food or the like will fall out and be scattered. is there. Furthermore,
If the distance between the knotting device and the table can be adjusted, the operation of placing the box on the table or unloading the box from the table becomes simple and easy, and the workability can be improved. In addition, when adjusting the distance between the knotting device and the table, if the knotting device is fixed and the table is raised and lowered, the distance adjusting mechanism has a simple structure and easy operability.
