The present invention relates to an automatic bending device for a packing box.

In the present invention, the banding device refers to a device that bundles the packaging box manufactured by the packaging box manufacturing apparatus (gluing machine) in a certain amount (about 20-30 sheets) in order to facilitate transportation and storage, which is glueing. Conveyor boxes are delivered to the machine by a belt band to wrap the boxes.

However, the conventional automatic banding machine stops moving when the transported packing box reaches a certain point. At this time, the banding is wrapped around the banding frame by manually operating the switch, and the band is wrapped and then moved again. By stacking the packaging boxes with human hands one by one, there is a need for additional manpower. Also, this bending work must be carried out in two lines or "+" through the transfer line. There was also a problem of bloating.

The present invention has been made in order to solve this conventional problem, the two banding machine is installed at the front and rear to perform the bending at the same time, the front is fixed to the main frame, the rear banding machine is installed to move back and forth In order to be able to cope with the size of the packing box when bending, the front and rear pivoting boards, which are operated by hydraulic cylinders, and a pair of left and right pivotal blocking arms are installed on the front and rear sides, respectively. By installing a pair of vertically moving reciprocating pressure plate and lateral movement pressure plate, it is possible to arrange the front, rear, left, and right of the irregularly stacked packing boxes in order, and at the same time pressurize the upper part of the packing box to flow during bending. To be tightly bound and prevent the bending of the guide rollers of the transfer belt It is installed up close to the up part to prevent the packing box from sliding in the bending work part, and the conveying belt is guided to each guide roller over the entire length of the main device so that there is no gap when the rear banding machine moves. On the basis of the accompanying drawings, the configuration according to an embodiment of the present invention will be described in detail as follows.

On the outside of the front and rear support frame 34, a multi-row feed belt 4 and a discharge belt 5 are delivered to each guide roller and are installed to operate as independent power sources. Inside the frame 34, front and rear banding machines 6 and 7 are installed. The front banding machine 6 is fixed on the lower frame 33, and the rear banding machine 7 is provided with rack gears at the bottom. It is engaged with the pinion gear on the lower frame so as to be movable back and forth.

The guide rollers 6 and 7 are arranged on the front and back support frames 34 by a plurality of guide rollers 16 arranged on the upper, the lower and the lower part of the body except for the bending work section 29. The multi-row conveying belts 18 spanned by (17) are guided in an infinitely orbital manner as shown in FIG. 5, so that there is no gap except the bending work part even if the rear banding machine 7 is moved back and forth.

The bottom plate assembly 1 is provided with a bottom plate 8 which is pivoted up and down by the hydraulic cylinder 12 so that the end portion almost contacts the surface of the conveying belt, and the pressure plate assembly 2 is a vertically moving pressure plate assembly 2A. It consists of a left and right moving platen assembly (2B), the shanghai east plate assembly (2A) is a rack gear 20 is installed on the rear side of the guide 21 is installed from the center of the platen assembly 2 to the bottom The hydraulic cylinder 13 is fitted so that the up and down movement can be adjusted by the upper pinion gear 23. The hydraulic pressure plate 9 is connected to the hydraulic cylinder by a piston. It is also provided on the left-right rotation blocking arm assembly 3 mentioned later.

In the left and right moving pressure plate assembly 2B, the upper bracket 36 is fitted on the rotation shaft 24 provided on the support plate 35 at the lower ends of the pressure plate assembly 2, and the left and right sides of the pressure cylinder assembly 2B are left and right. The moving platen (10) is connected to the structure, and on the opposite side of the rotating shaft is fitted to the fixed plate (10 ') and the rotating shaft 24 is rotated by forming a screw in the opposite direction from the left and right in the center, the left and right moving pressure plate (10) and the fixed plate (10) ') Is collected inward or outward.

Similar to the rotary shaft on the upper plate assembly, the left and right pivot blocking arm assembly 3 has a pair of opposed brackets 37 installed on the rotary shaft 25 having opposite and opposite screws at the center thereof, respectively. ) Are installed in a position opposite to each other, these are connected to the piston of the hydraulic cylinder (15) by the lever (38) is to move left, right.

The rotating shaft 24 on the pressure plate assembly and the rotating shaft 25 of the left and right pivot blocking arm assembly are respectively interlocked with the interlocking bevel gear 27 on the horizontal axis 28 fixed to the frame with bevel gears 26 installed at the ends thereof. In the left and right movement pressing plate assembly (2B) and the left and right rotation blocking arm 11 is adjusted at the same time.

The structure of the front and rear banding machine (6) (7) has a band supply frame (30), the frame (3) having a guide for feeding the band in a snare type and the banding work portion (29) for thermally bonding the ends of the collected bands ), Which is the same as a known banding machine structure.

On the other hand, the front and rear banding machine (6) (7), the power source (motor) of the transfer belt 18 connecting them, the bottom plate assembly (1) up and down moving platen assembly (2A), left and right moving platen assembly (2B) Sensors are installed in each of the cylinders 12, 13, 14, and 15 of the rotation blocking arm assembly 3 to connect power to a separate control box to automatically adjust the operation order of each device. After moving and up / down movement, the left and right movements can be made by manual operation of the lever on each side of the pinion gear or automatically by connecting a separate power source. By inserting a knurling bushing, the friction force can be further increased during the transfer of the object, so that the transfer can be made better.

Referring to the bending working example in the state configured as described above are as follows.

First, when the apparatus is operated, the feed belt 4 and the feed belt 5 for discharge are always rotated in one direction, and the feed belt 18 for connecting the front and rear banding machines 6 and 7 is also rotated. Thus, a pile of packing boxes from the gluing machine is placed on the feed belt 4 for feeding and moved toward the front banding machine 6, where the bottom plate 8 of the bottom plate assembly 1 is lifted up and the pressure plate assembly 2 The shanghai pressure plate 9 and the left and right movement pressure plate 10 and the shanghai pressure plate 9 on the left and right pivotal arm assembly 3 also have a pair of pistons in the cylinder so that they do not meet the feed path. Only the left and right pivot blocking arms 11 are rotated in a state in which the transport path is blocked. Therefore, the packing box pile is transported to the upper left and right pivot blocking arm 11 and continues to be restrained. Here, the positions of the left and right pivotal blocking arms are the bending work areas 29 of the front and rear banding machines 6 and 7 on both sides of the upper surface of the packing box. It should be adjusted accordingly, and the left and right moving pressure plate 10 is slightly wider than the left and right sides of the packing box, the bottom plate 8 should be adjusted to the same position as the packing box length from the left and right rotation blocking arm (11). On the other hand, when the packing box touches the left and right pivot blocking arm, the sensor of each cylinder and power source detects this and sends a signal to the control box, and receives the signal from the control box to instruct each device again. (13) (14) (15) are operated simultaneously and stops the power source of the banding machine (6) and (7) connection transfer belt (18).

Therefore, the operation of the conveying belt is stopped and the bottom plate 8 is pushed toward the front of the rear of the packing box to arrange the disheveled state. At the same time to prevent swelling and at the same time the bending operation is made at the front and rear banding machine (6) (7).

When the bending operation is completed, the tightening state of the upper, lower left, right, and rear sides is released by reversing the original indication state in the control box and the transfer belt 18 connected to the front and rear banding machines is operated to wrap the banding in two places. Box bundle is to be conveyed to the conveying belt (5).

Therefore, the whole process from supply of packing box to pre-bending trimming, 2 simultaneous banding, and discharging can be done automatically, greatly reducing work time and drastically reducing labor costs without any manpower requirement.
