In general, the crusher refers to a machine that completes the shape of a box-shaped box that is opened to wrap a product and fill it in a box.

That is, a box is used to store or store an object or a product. The maker of a box delivers an unopened box to a user to facilitate the transfer of the box.

Therefore, in order to put things inside the box, the user of the box must open the box, fold its wings into the shape of a cube, and attach the tape to the bottom.

However, this slows down the box packaging process, which is quite cumbersome for companies that need to pack a lot of things in a short time.

Of course, there is a limiter such as the present invention to solve this.

Then, look at the working form of the conventional general crusher as follows.

By the way, there existed a lot of problems in such a conventional box K.

That is, although the above-mentioned delimiter has been described as a fully automatic de-energizer, a fully automatic de-energizer is often more troublesome depending on the workplace.

In particular, a fully automatic delimiter is unnecessary in a workplace that does not require continuous decontamination work, that is, only a few boxes and then several boxes again.

In addition, in the case of small workplaces, the working space is likely to be narrow.

However, the above-mentioned automatic blocker is often impossible to install because its volume is so large that the space to be installed must be large.

In addition, in the case of a workplace that requires the packaging of the intermittent box, the operation of turning off the gas and turning it back on again should be repeated, but the conventional type of chopper has a disadvantage in terms of economics because of high power consumption.

In order to solve this problem, there is a "folder folding device of the box" including the present invention, the present invention, pusher interlocking unit is essential to push the box more stable and less expensive Compared to any existing interlocking means, it is simple, but the manufacturing cost is low and the durability is high.

In addition, a switch unit 70 configured at one end of the base 10 to operate the forward pusher 50 is formed.

Accordingly, the pusher interlocking unit and the forward pusher 50 are coupled to the upper portion of the wing support plate 20 through the guide fastening means 40, and the box 1 is connected to the tapered surface 51 of the forward pusher 50. The vertical wing (A) is folded, the air cylinder 31 in the interior of the body 10 by interlocking the horizontal wing folding plate 35 to fold the horizontal wing (B) of the box 1 forward pusher (50) To be discharged.

That is, as described above, the present invention allows the worker to push the longitudinal wing (A) of one side of the box (1) to the tapered surface 51 of the forward pusher 50 to be folded naturally, one side folded using his hand It is to be folded in close contact with the upper portion of the wing support plate (20).

Then, the transverse wings B of the box 1 are accommodated inside the base 10 in the unfolded state.

In this case, since the limit switch 85 is provided at the lower end of the forward pusher 50 illustrated in FIG. 7, the lower switch 85 collides with the lower end of the box 1, and the wrist switch 85 is pressed by this action.

Therefore, the folding plate driving means 30 is electrically connected to the pressurization is to fold the horizontal blade (B), the configuration and operation will be described as follows.

That is, the folding plate driving means 30, as shown in Figure 5, there is an air cylinder 31 of both sides fixed to the left and right hinged to the inside of the base 10, the shaft end of the air cylinder 31 The coupler 33 fitted in the structure is comprised.

In addition, a horizontal wing folding plate 35 coupled to the hinge 34 at the end of the coupler 33 is formed.

Accordingly, the hinge 34 is coupled to the coupler 33 by contraction and expansion of the cylinder shaft, and the horizontal wing folding plate 35 is pivoted up and down by the hinge 36 to fold the horizontal blade B.

In other words, when the above-described limit switch 85 is clicked, the folding plate driving means 30 automatically operates so that the air cylinder 31 extends its axis.

This action is because the coupler 33 is coupled to the end of the shaft, the horizontal wing folding plate 35 is coupled to the end of the coupler 33 through the hinge 34, so as to extend the horizontal wing folding plate (35). Is raised.

However, as shown in FIG. 5, the horizontal wing folding plate 35 rotates the fixed hinge 36 on its axis because one side thereof is coupled to the fixed hinge 36.

Of course, the horizontal wing (B) of the box (1) that was accommodated into the interior of the body 10 by the rotation is folded, as shown in Figure 5, is folded in a state wrapped around the wing support plate (20).

In this state, the box 1 overlaps with the horizontal blade B, and the worker pushes the folded box 1 to be discharged. This is achieved through the guide fastening unit 40 and the forward pusher unit 200 which will be described later. .

Therefore, to describe in detail the configuration and operation of the guide fastening means 40 and the forward pusher unit 200 in order, the guide fastening means 40 of the forward pusher 50, the lower end of the forward pusher 50 And a screw fastened to each other, there is a guide pin 41 fitted into the guide hole 21 of the wing support plate 20, and is connected to the other side of the guide pin 41 to be accommodated into the base 10. There is).

In addition, a clamp block 43 screwed to the end of the connecting plate 42 is formed.

Therefore, the forward pusher 50 and the connecting plate 42 are fastened by the guide pins 41, and the clamping plate 43 coupled to the pusher interlocking unit 200 is fastened to the connecting plate 42 by the pusher interlocking unit 200. In accordance with the operation of the forward pusher 50 to interlock.

That is, the guide fastening means 40 of the forward pusher 50 serves to keep the forward pusher 50 protruding on the upper end of the base 10, by combining with the pusher interlocking unit 200 to be described later The forward pusher 50 is interlocked with the guide hole 21 formed in the wing support plate 20 to serve to retract the folded box.

For that purpose, as shown in FIG. 6, the lower end of the forward pusher 50 engages the forward pusher 50 by fastening a nut to a thread provided at one end of the guide pin 41, and the other of the guide pin 41. The side has a bolt head so that the bolt head is coupled to the above-described connecting plate 42 so that the connecting plate 42 and the forward pusher 50 are kept in an integrated state.

Of course, in the guide fastening means 40 having the forward pusher 50, the clamp block 43, which is a separate configuration for coupling with the pusher interlocking unit 200, is configured as shown in FIGS. 5, 6, 8, and 9.

That is, the clamp block 43 is configured at the end of the connecting plate 42 to couple with the pusher interlocking unit 200.

That is, this pusher interlocking unit 200 is the present invention.

3 and 9 illustrate the configuration and operation of the present invention, the main pulley 211 is formed with two guide grooves 213 coupled to the shaft 212, one side of the base 10 There is a cylinder 210 fixed inside the stage, and is rotatably fixed to the left and right ends of the body 10, the first pulley 220 and the second pulley 230, the guide grooves (221, 231) formed on the outer peripheral surface There is).

In addition, the wire 240 is connected between the pulleys (211, 220, 230).

Therefore, the wire 240 fixed to the left end of the base 10 (based on FIGS. 6 and 8) is wound around the main pulley 211 and wound around the second pulley 230 via the first pulley 220. It is wound on the main pulley 211 again, and is fixed to the right end (based on FIGS. 6 and 8) of the base 10 again, and the clamp block 43 of the forward pusher 50 is fixed to one side of the wire 240. It is.

That is, when the worker has completely folded the horizontal blade (B) and the vertical wing (A) of the box (1), the bottom wing is folded out of the box (1), the switch unit configured on the upper surface of the base 10 70 is to click.

This click causes the cylinder 210 to extend its axis 212, and the extension of this axis 212 pulls the wire 240.

In other words, the main pulley 211 having two guide grooves 213 is fixed to the end of the shaft 212, and the first pulley 220 and the second pulley 230 are formed on both left and right sides of the base 10. ) Is in a fixed state, and they are connected through the wires 240 shown in FIGS. 6 and 8.

Accordingly, when the shaft 212 of the cylinder 210 fixed to the left side of the base 10 moves in the right direction, the main pulley 211 also moves accordingly.

Of course, at this time, since the wire 240 is hung on the main pulley 211, the wire 240 is pulled back around the outer circumferential surfaces of the first pulley 220 and the second pulley 230.

As a result, the extension of the cylinder shaft 212 is moved from the state shown in FIG. 8A to the state shown in FIG. 8B. One side of the wire 240 of the present invention moves forward through the clamp block 43 shown in FIG. 50) is combined,

Therefore, the extension of the shaft 212 of the cylinder 210 serves to retract the box 1, which is folded under the wing, to the left side of the drawing.

6 and 8 and 9 of the present invention, a tension spring 250 for absorbing the vibration of the wire 240 is connected to the wire 240 fixed to the base 10.

The tension spring 250 is likely to generate vibration in the wire 240 by a load generated when the shaft 212 of the illustrated cylinder 210 is extended and contracted at a high speed.

Therefore, it is desirable to mount these to absorb these loads organically to make the operation of the gas more smooth.

In addition, it is preferable to connect the turnbuckle 260 to adjust the tension of the wire 240 to the wire 240 fixed to the base 10 as shown separately from this.

The turnbuckle 260 may increase the wire 240 through frequent operation of the gas, and is used to adjust the tension of the wire 240 when the pusher interlocking unit 200 of the present invention is mounted. .

When the wire 240 is fixed with too much tension, the friction force between the pulleys 211, 220, 230 and the wire 240 may increase and may operate in a stiff state. When the wire 240 is fixed with too little tension, the wire ( 240 is likely to peel off the pulleys (211, 220, 230).

Therefore, by appropriately rotating the turnbuckle 260 to adjust the tension.

Moreover, in order to compensate for the gap between two guide grooves 221 and 231 formed in the main pulley 211, the second pulley 230, that is, the pulley on the right side based on FIG. 8 is illustrated. It is coupled to the base 10 obliquely by the distance.

That is, although the state shown in the reverse direction in FIG. 9, the second pulley 230, which appears to be formed on the left side opposite to the diagram of FIG. 8, is fastened in a state in which the frame is twisted by an angle θ in the vertical direction.

The reason is that the main pulley 211 illustrated in FIG. 8 has two guide grooves 213 formed therein, and a long wire 240 is wound around the guide grooves 213.

Therefore, the wire 240 wound around the guide groove 231 of the second pulley 230, the main pulley to return to the position of the wire 240 and the second pulley 230 transmitted from the first pulley 220. The position of the wire 240 entering the 211 is a phase difference as much as the difference between the two guide grooves 213 formed in the main pulley 211.

As a result, the phase difference between the wire 240 entering the upper end of the second pulley 230 and the wire 240 exiting the lower end of the second pulley 230 is the distance of the guide groove 213 formed in the main pulley 211. In order to compensate for the distance, the second pulley 230 is mounted by twisting by θ.

This will reduce the frictional force acting between the wire 240 and the guide grooves (213, 221, 231) of the pulleys (211, 220, 230), and also reduces the action of the torsional stress to smooth operation.

In the present invention, as shown in Figures 8 and 9 in the vicinity of the second pulley 230,

The limit switch R is fixed.

That is, the interlocking space of the main pulley 211 which is fixed to the end of the shaft 212 when the cylinder 210 extends the shaft 212 in the vicinity of the second pulley 230, more precisely The limit switch (R) is fixed to.

Therefore, when the cylinder 210 extends and pushes the shaft 212 and clicks the limit switch R configured at the end thereof, the cylinder 210 is electrically connected to reduce the shaft 212 again automatically. .

Then, looking at the state of the overall operation of the present invention, when the worker folds the lower wing by the other components of the lower wing folding device, it will click the switch unit 70 attached to the upper surface of the base (10).

This click acts as an extension of the shaft 212 of the cylinder 210, which extends the wire 240 twice the distance of the shaft extension.

Accordingly, the forward pusher 50 fixed to the clamp block 43 at one side of the wire 240 is moved by the same distance as the wire 240, and the box folded by the lower wing is moved forward by this movement. It is pushed by the pusher 50 and exited out of the gas 10.

When the shaft 212 of the cylinder 210 is extended to press the above-described limit switch R, the sensing unit 210 detects this and reduces the shaft 212 of the cylinder 210 to prepare for the next work.

As described above, the present invention is a useful invention that is easy to be applied to the "winger folding device of the box", the production is simple and can be produced at a low cost.

In addition, the present invention has the advantage that the volume can be reduced during the production of the gas because it is possible to move horizontally about twice the length even if a cylinder of 1/2 length compared to the moving distance inside the body.

In addition, the present invention is an invention of high utilization, which can achieve smooth and smooth horizontal movement, high durability, and stable interlocking by organically combining only the cylinder, the pulley and the wire.
