The present invention relates to a side wing holder of a bending device for a double wall paper box manufacturing machine.

If the contents need to be protected from external impact or the circular holding force of the box is to be large, a paper box of double side plates 502, 502a, 504, 504a forming a four-sided edge is used. For this purpose, a double wall paper box manufacturing machine should be used. The machine shown in FIGS. 2a and 2b schematically shows a machine manufactured by the applicant. This means that the stacked double wall box 500 can be loaded and operated up and down, a loading part 100, a conveying part 120 that sucks up one unfolded double wall box 500 with a vacuum and fits it into a belt conveyor, and one deployed double wall box. Belt conveyors 130 and 140 for transporting the to the lower part of the bending part, centering device 190 for finally pulling the unfolded double wall box transported to the lower part of the bending part and maintaining it in the correct position, and deploying staying in the correct position by the centering device. Pressed double wall box is made of a bending part 160 to bend the side plates of the four sides and a molded part 150 to make a completed double wall box 550. On the other hand, the present invention is installed on the lower end of the four rods 162, 162a of the bending part 160, and the side wings 505, 505a of the double wall box 500, which has been transferred to the mounting table 200, to be fitted in the side wing insertion groove 1. It descends along with the bent part 160 to provide a side wing holder to finally manufacture a finished double wall box 550.

The conventional double wall paper box manufacturing machine and its bending parts have a big structural difference from the present invention, and have a complicated structure and have a high incidence of failure and error, especially when the size of the box is changed. There are many problems, such as changing the device only through complicated procedures. In other words, if the size of the machine is very large and the size of the box is changed, the number of parts to be replaced is too large, and it is almost impossible to operate it without a skilled technician. In addition, since the device for holding the side wings of the box is complicated, the number of parts is high, and the incidence of errors is high, the development of a side wing holder having a simple structure and almost no incidence of errors has been required. do.

It is therefore an object of the present invention to provide a side wing holder of a bending device for a double wall paper box manufacturing machine having a simple structure and a near zero occurrence of failure or error.

In order to achieve the above object, the present invention is installed on the lower end of the bar of the bending part of the double-wall box manufacturing machine double wall paper completed by lowering toward the forming part together with the bending part while sandwiching both side wings of the double-wall paper box. A side wing holder for making a box; The outer surface is a side blade insertion groove is formed horizontally so that the side wings of the box can be fitted into the bite.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In the following description, it should be noted that only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

As shown in FIG. 6, the present invention "A" has a side wing insertion groove 1 in which both side wings 505 or 505a of the box can be fitted on the outer surface of the rectangular plate body, and the side wing insertion groove is formed. The lower end connecting 1 is formed with a bend line leading end 2 which can accurately press the bend line 5 of the developed box as shown in FIG. 1A. That is, as shown in FIG. 3, the bent line pressing end 2 stays at a position coincident with the bent line 5 of the unfolded double wall box 500, wherein the side wings 505 and 505a are inserted into the side wing insertion groove 1 of the present invention. It becomes a state. The detailed action of this will be described later.

On the other hand, looking at Figures 2a, 2b (2a and 2b is originally expressed in a single drawing, but it is clear that it is divided in half by editing.), The bending part 160 to which the present invention is installed is the belt conveyor 130, 140 It can be seen that it is located on the left side and directly above the forming part 150. In this state, when one unfolded double wall box 500 loaded in the loading part 100 enters between the belt conveyors 130 and 140 by the action of the conveying part 120, the belt conveyor transfers the unfolded double wall box 500 to the end of the left side and mounts 200. To the top of the. However, it is natural that the double wall box 500 developed by the conveying force of the belt conveyor is difficult to maintain the correct position on the guide 180. Therefore, the centering device 190 must be used indispensably to accurately position the deployed double wall box. When the position of the double wall box 500 developed by the centering device is correctly fixed, the bending part 160 descends immediately.

On the other hand, the state of FIG. 3 and the state of FIG. 4 show the same state in which the deployed double wall box is placed on the mounting table 200. The side wings 505 and 505a of the deployed double wall box forcedly transferred to the mounting table by the belt conveyor are As shown in FIG. 3, the two guides 175 and 177 are moved while being inserted into the grooves "K" formed. This state is the same as that of FIG. The guides 175 and 177 are located at both sides in a direction parallel to the moving direction of the double wall box as shown in FIG. However, in this state, when the bending part descends and pushes down the unfolded double wall box, the side wings 505 and 505a escape the groove "K" and at the same time, it is developed as the original by the elasticity of the paper box on the basis of the bend line 5. The state will be restored immediately. Therefore, not only the desired purpose can be achieved, but also the failure or breakage of the device is caused. For this reason, the holder of the present invention plays a very important role in solving the problem.

The present invention is installed at the lower ends of the four rods of the above-described bending parts, the lower end of the rod is assembled with the bracket 163 and the reinforcement 165 is attached to the outer surface of the bracket 163. The reinforcement 165 is fixed to the bracket 163 while being tightened by the fastener 166 at the bottom without the fixing means by itself, which is possible by assembling the bolt 167. On the outside of the reinforcement 165, the holder "A" of the present invention is assembled by a countersunk head screw so as to be parallel to the longitudinal direction of the reinforcement 165, and the side blade insertion groove 1 faces outward.

On the other hand, the holder "A1" of the present invention is to bend the bending line 6 before and after the unfolded double wall box, it can be seen that the side blade insertion groove is also formed. However, in fact, the holder "A1" does not need the side wing insertion groove, so it can be omitted, but from the productive point of view, it is uneconomical to produce and use each with and without side wing insertion grooves. The holder "A" of the present invention in which the groove is formed is shortened and used as it is.

And the support rod 170 is assembled on the upper surface of the guide 175, the support rod 170 is assembled to the main frame. Before and after the support rod 170, four support 171 is attached, as shown in FIG. 5, between which the plate body 172 is assembled by bolts, and the air cylinder 173 is assembled in the center of the plate body 172. In addition, the piston rod of the air cylinder 173 is assembled with a pusher 174 bent in the shape of the letter "a". The bending part is installed in the auxiliary frame 50 on the main frame, among which the air cylinder 181 is assembled to the main frame. The double wall box 500 developed as described above is fixed on the mounting table 200 and the air cylinder 181 operates to lower the lever 185. The lever 181 raises or lowers the support 161 while performing circular motions with the pin 184 as the center of rotation. Let's do it. In the support 161, four rods 162 and 162a are formed in all directions as shown in FIG. 5, and among them, an air cylinder 180 is assembled at the upper side of the rod 162a in front and rear (based on FIG. 5), and the support 161 is lowered. Accordingly, all four rods descend, and only two rods 162a are raised by the operation of the air cylinder 180 later. Detailed description thereof will be described later.

Hereinafter, the operation of the present invention and the bending of the box will be described in detail.

As described above, the deployed double wall box 500 forcibly moved with the side wings 505 and 505a in the groove "K" between the guides 175 and 177 is centered in the correct position by the centering device on the mounting table 200, and then Waiting for you. Next, the bending part 160 is lowered to bend the box. As described above, since the side wings 505 and 505a must not escape from the groove "K", the air cylinder 173 is operated so that the end of the pusher 174 is shown in FIG. Likewise, by hitting the bent portion that forms the boundary between the side plates 504, 504a and the side wings 505, 505a, the side wings 505, 505a can escape from the groove "K", and the side wings 505 escape the groove "K". , 505a is inserted into the side wing insertion groove 1 of the present invention and then immediately returned to its original position. This state is the same as that of FIG. 1C. Subsequently, the bending part 160 descends immediately so that the bent line pressing end 2 of the present invention lowers the unfolded double wall box while pressing the bending line 5. Of course, bending line 6-2 of the holder "A1" of the present invention is in contact with the bending line 6, which naturally makes the bending line 6 bent. Here, the side wings 503 and 503a are not interrupted by anything.

As described above, the side blades 505 and 505a are sandwiched in the side wing insertion groove 1 of the present invention, and the bending points 2, 2-1 of the present invention are pressed while bending the respective bending lines 5 and 6 above. When the part is lowered, the corners 506 of the four corners are first folded and folded by the four corner bending guides 204, and then the front and rear side plates 502 and 502a start to be folded up by the front and rear guides 201, The side plates 504, 504a also start to be folded up by the two left and right guides 202. Subsequently, the shape of the expanded double wall box which passes through the lowermost guide 203 and is positioned on the protruding end 151 of the forming part 150 is in the state as shown in FIG. That is, in the side wing insertion groove 1 of the present invention, the side plates 504, 504a are formed at right angles with the base plate 501 while the side wings 505, 505a are sandwiched, and the side plates 502, 502a are erected without folding as shown in the figure. It is in a state. In this state, the folder 152 should be erected by folding the side plates 502 and 502a inward. At this time, the bending line 6 of the holder "A1" of the present invention is in contact with the bending line 6 before and after the folder 152 to operate. I can't. Therefore, the cylinder 180 immediately starts to raise only two rods 162a (front and rear rods). Therefore, in the state of FIG. 1d, the side plates 502 and 502a do not interfere with anything. Immediately, the air cylinder 154 is operated to raise the rack gear 155, and the folder 152 held in the rack gear 155 is rotated 180 degrees inward to turn the side plates 502 and 502a inward. At this time, the wings 503 and 503a of the side plates 502 and 502a are naturally unfolded with the side plates 502 and 502a folded inward as shown in FIG. 1E. Even in this state, the side blade insertion grooves 1 of the holder of the present invention are inserted into the side blades 504 and 505a of the side plates 504 and 504a, and the bending line pressing end 2 is pressing the bending line 5 as it is. Subsequently, the air cylinder 173 is operated again and the support 161 is returned to its original position. As a result, the rod 162 rises and returns to its original position. At the same time, the side wings 505 and 505a, which are sandwiched in the side wing insertion groove 1, are increased by the side wing insertion groove. 1 slide down and spread down by the elasticity of itself and blow. In this state, the side wings 505 and 505a are finally unfolded while being pressed against the upper sides of the already folded side wings 503 and 503a. Therefore, the box does not restore itself while maintaining the same shape as that of FIG. As described above, when the box is completed, the air cylinder 153 of the molding apparatus 150 is operated to pull the protruding end 151, and immediately the completed box is dropped onto the belt conveyor 156 and transported to the outside of the machine. The operation as described above is repeated and the box continues to be produced.

On the other hand, Figure 7a is the inner upper side of the side blade insertion groove 1a is an arc and the bent line pressing end 2a is formed, Figure 7b is also the side wing insertion groove 1a is a "c" shape while pressing the bent line Tip 2a is formed, and in FIG. 7C, another plate 80 is assembled on the bottom of the plate by bolt 81, the end portion of which forms a bent line pressing tip 2a, and upwards of the protrusion 70 on bolt 71. By being assembled by the side wing insertion groove 1a is to be formed. These show a state that can be changed commercially very easily from the present invention, the holder is formed with the side blade insertion groove 1 or 1a is not deviated from the technical scope of the present invention did not exemplify any further changes. . And the holder of the present invention can be used simply by welding to the bottom of the rod without necessarily having to be assembled as shown in Figure 3, but if the size or type of the box to be manufactured is changed so that the holder of the present invention can be easily replaced It is reasonable to say that it is the most desirable and it is natural to prefabricate.

In the present invention as described above, the side wing (long side wing) of the bent paper box can be snapped very simply and securely while disassembling and assembly is made on the bracket at the bottom of the rod. By facilitating the generation of the defect rate in the bending action of the paper box to almost zero can be realized as well as this has a useful effect of making a good paper box can be produced. In addition, the present invention is extremely simple in structure, there is little fear that the occurrence of failure or error occurs, and excellent durability, and the convenience of repair and replacement work also has an excellent effect compared to the conventional.
