Description

Joining machine for wrapping box

The present invention relates to a packing box jointer for joining the joint of the developed paper of the packing box to make a packing box, and in particular, the paper feed roller is composed of an upper roller and a lifting lowering roller, and the paper fed by the stopper of the alignment device When the rollers are aligned in the correct position, the lower and lower rollers are raised to press the paper together with the upper rollers so that they can be fed to the rear pressing rollers without distortion, and the quality of the product can be greatly improved. The present invention relates to a packaging box jointer installed so as to be aligned in a line so that the bonding of the two-ply bonding box can be performed even with one feeding.

In the related art, a packing box bonding machine is usually provided with two paper feed rollers simply arranged in a line on the left and right, a compression roller located at the rear, and a division jig for joining.

Therefore, only two left and right paper feed rollers are pressed and fed to the press roller. Therefore, the paper box of the paper box being fed is pressed by only two rollers on the left and right to be transported to the rear, and thus the position of the paper being fed is very frequently distorted during feeding, which causes the joint of the product to be crooked. In many cases, poor quality occurs.

In addition, since the conventional packing box bonding machine has only two feed rollers on the left and right sides, there is a serious misalignment of the paper being fed. There is a problem that it cannot be used for joining a box for double bond joining, which completes a packing box.

In addition, the conventional packaging box bonding machine as described above is often inadequately brought about poor bonding due to the lack of suitable means for aligning and feeding the paper to be fed.

In addition, the conventional packaging box jointer as described above has a problem that it is impossible to join a box of a wide and low height, and a long special shape (since there is no means for holding and feeding the paper without twisting), I'm putting it.

The present invention has been made in order to solve the problems of the conventional packaging box bonding machine as described above, and to provide a packaging box bonding machine that can feed the paper sheet without distortion and stably feed the paper until the adhesive coating is completed for that purpose. do.

Another object of the present invention is to provide a packaging box jointer having the function of a double bonder.

This object can be achieved by the present invention having an upper feed roller and a lifting lower roller facing the same, having an alignment device having an alignment stopper, and having two or more pressing rollers in a transverse direction. It will be described in detail with reference to the accompanying drawings.

The feed rollers peculiar to the present invention are constructed in the above conventional apparatus. The feed roller of the present invention is composed of a front feed roller and a rear feed roller 7 as described above, but the present invention omits the rear feed roller in addition to this, and simply the upper feed roller 8 and the corresponding lower lower feed sheet. It can also be comprised only by the roller 8 ', and this also belongs to the scope of the present invention.

The rear paper feed roller 7 rotates the upper and lower rollers facing each other, presses the paper to be fed, and feeds it to the rear. However, in the front paper feed roller, the upper roller is always kept in the fixed position and lowered at the bottom. The roller is raised only when the paper is fed in the lowered state, and the paper is pressed together with the upper roller to convey the paper back.

The lifting lower roller may be achieved through various types of lifting structures. In an exemplary embodiment of the present invention, the lifting lower roller is rotatable at a predetermined angle by the hinge shaft 40 as shown in FIG. 41) is fixed to one end, the other end of the roller support 41 is fixed to the piston rod of the lower and lower roller drive cylinder 42 is configured to raise and lower the lower roller by the operation of the lower and lower roller drive cylinder.

In order to precisely align the precise operation control of the lifting lower roller and the exact position of the paper source to be fed, a special device is required, and the alignment device of the present invention provides it. Figure 4 shows such an alignment device of the present invention.

As shown in the figure, the alignment device 30 of the present invention is provided with a stopper 31 that pushes a predetermined amount of paper back to the front when paper is fed and contacts.

The alignment device is fixed to the horizontal movement cylinder 33 is fixed to the lower end of the stopper (31) to operate back and forth, the lower portion of the horizontal movement cylinder 33 is fixed to the vertical movement cylinder 34 to operate vertically, It is preferable that the stopper is configured to be movable back and forth and up and down.

An upper portion of the horizontal movable cylinder 33 of the alignment device is provided with an impact sensor 32 for detecting that the stopper is pushed back by being fed to the sheet of paper, and the vertical movable cylinder 34 is installed in the horizontal movable cylinder 34. It is preferable to allow the stopper drop detection sensor 35 to detect that the 33 has been lowered so that precise control is possible.

In addition, the lower and lower roller lift sensor (symbol 36 in FIG. 2) for detecting the lifted state of the lower and lower rollers is installed at a predetermined position of the body so as to be closely associated with the operation of the sensors of the alignment device, and the fed paper passes. It is also preferable to provide a position detecting sensor (reference numeral 37 of FIG. 4) for detecting one.

An example of use of the first embodiment of the present invention having the above configuration will be described below with reference to FIGS. 1 to 4.

First, when the base paper 50 of the cut packaging box is inserted into the feed roller, the base paper enters the lower portion of the upper roller 8 and impacts the stopper 31 positioned slightly behind the upper roller 8. . At this time, the lifting lower roller (8`) is lowered to the lower state does not prevent entry of the base.

As shown in FIG. 4, the stopper 31 is in a state where the initial state is raised upward. When the base paper enters and impacts, the stopper 31 is elastically bent to provide a shock sensor 32 located rearward. ) And the shock sensor detects it.

When the signal of the shock sensor is applied, the horizontal movement cylinder 33 is immediately activated to advance the stopper 31 by a certain distance forward, thus entering the base paper is discharged to the front by a constant interval again, the correct shear surface Will be aligned laterally. When the base paper is accurately aligned, the lifting lower roller driving cylinder 42 is operated to raise the lifting lower roller 8 '.

As described above, when the lifting lower roller 8` is raised, the roller rising sensor 36 detects this, and thus the vertical movement cylinder 34 contracts so that the stopper 31 descends.

When the stopper drop detection sensor 35 is operated by the lowering of the stopper, the front feed rollers 8 and 8` rotate, and thus the lower end roller 8` of the end of the sheet of paper 50 that has entered enters. And the upper roller 8 is squeezed up and down to transfer the base paper in a state in which the base paper is stably squeezed backwards.

In this way, the fabric fed back is continuously pressed by the rear feed roller 7 while the adhesive is applied to the adhesive part 51 by the adhesive applying means (hot melt, etc.) installed below the division jig 11 from the front end portion. It is transported and the adhesive portion 51 of the base paper 50 by the pressing roller (5) is pressed while being bonded and transported and discharged to the rear is completed to complete the packaging box.

If the paper passes the front feed rollers (8,8`) in the above process, the position detecting sensor 37 installed at the upper predetermined position of the front feed roller (possible to install at an appropriate position in the design) detects this and moves the lowering roller. (8`) is lowered again and the stopper 31 is raised again.

Of course, it would be desirable to control all the above processes by the controller.

As described above, the present invention performs the bonding operation by feeding the paper without twisting due to the accurate alignment of the paper and the stable feeding of the paper. It will not be.
