Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for attaching a cutting blade to a carton, which allows the cutting blade to be attached to a carton at any position from the tip to an intermediate position.

[Prior Art and its Problems] Conventionally, there have been various structures of cutting blade attachment devices for cartons. According to this attachment device, it is certainly possible to attach the cutting blade to the carton, but the attachment position of the cutting blade to the carton is the one for attaching only the tip (hereinafter referred to as "
(hereinafter referred to as "those for mounting at the tip"), or those for mounting at any position in the middle (hereinafter referred to as "those for middle mounting");
types exist. That is, the end attachment type is attached to a carton that mainly accommodates aluminum foil and the like, and the intermediate attachment type is attached to a carton that mainly accommodates synthetic resin film and the like.

In order to operate these two types with the same machine, the mechanisms for stopping the cartons are different, so it is necessary to completely replace a part of the machine, which not only takes time, but also requires a lot of time. There was a defect that reduced production efficiency by half.

In addition, in the case of intermediate attachment types, the cutting blade is often attached with a slight deviation.

That is, as shown in FIG.
As shown in FIG. 32, there was a slight inclination of a slight angle Δθ. Even if there is a slight deviation like this, when assembled as Carton A, the blade of the cutting blade will not protrude from the corner of the box, and it will not only be completely useless, but also cause the blade to not exist at all. There were drawbacks. Also, there were times when it came out too much and was dangerous. For this reason, in the case of intermediate mounting devices, if the speed is about three strokes per second, the speed is too high, and it is often difficult to mount them in a more accurate position.

[Means to solve the problem]

[Effect]

First, a case where the carton a comes into contact with the intermediate attachment stopper pin 13 will be described. That is, when the cutting blade is struck at an appropriate position in the middle of the carton δ, when the cutting blade is struck at a position several inches from the tip of the carton a, the carton is first attached to the main part 23 of the tip attachment stopper. a is raised so as not to come into contact with it (see FIG. 23), and the binion 20 is rotated appropriately, and the front and rear adjustment plate 18 is adjusted back and forth through the rack 19 and set at a predetermined position. Also, depending on the finish of the carton a and the shape of the carton a, in order to make the cutting surface of the cutting blade protrude the same width from the corner of the box-shaped carton a, it is necessary to Mounting stopper pin 13. It is necessary to shift i3 slightly, but in this case, before and after independence! J1 section board 21
, 2I are adjusted back and forth as appropriate by appropriately rotating the screw rods 22, 22.

Here, mold part A corresponds to attaching the cutting blade to carton A.
To describe the working process, the cutting blade that has been punched in the pre-processing is moved in one step (feed controlled by appropriately adjusted pulse signals) between the punch 12 and the upper blade 5. amount) sent.

In reality, it is possible to obtain a feed amount in units of several hundredths of a width.

The width of one step is such that the cutting blade is fed by a desired length from the cutting edge of the upper blade 5 to the left in FIG. Therefore, first, the lower die set A z is raised,
The lower blade 6 and the metal plate feeding guide IO rise. Then, the upper surface of the metal plate feeding guide 10 comes into contact with the lower surface of the upper blade 5, and the tip of the metal plate p is held between the lower surface of the upper blade 5 and the metal plate feeding guide 10. This is to make it easier to cut the metal plate p. Immediately after this, the tip of the metal plate p is cut by the rising lower blade 6 and upper blade 5, and the metal plate p further rises while being held by the magnet provided on the upper surface of the lower blade 6 as a cutting blade. (See Figure 21)
During this upward movement, the carton a is fed from the left side by the drive belt 34 and free roller 38 of the transfer pressing structure C1 for the carton a, and passes through the flat feed hole 8 of the upper die set A. , the carton a is stopped at the tip of the intermediate attachment stopper pin 13.13 which has already been lowered. Then, the lower blade 6 rises, and the piercing punch 12 punches a piercing hole at the tip of the metal plate p where it will become the cutting blade to be cut next. A1
It enters the punch hole 5a of the upper blade 5. When the lower die set A further rises, the cutting blade, which is held by the lower blade 6 and continues to rise, cuts into the carton a, which is still waiting in the flat feed hole 8 of the upper die set A1. The cutting blade is fixed to the carton a. The reason why the carton is fixed in this way is that the carton a has a certain thickness and the cutting blade has a small thickness. Simultaneously with the completion of such fixing, the stopper pins 13, 13 for intermediate attachment are raised, and when the carton a with the cutting blade is transferred rightward in FIG. 23 by the transfer pressing structure C1, the transfer pressing structure C1 The punch roller 39 and the pinch roller 41 of the punch roller 40 of the discharge section, which is several times faster than the feeding speed of .

This completes the entire process of raising the lower blade 6, that is, the lower die set At, and then the lower die set A8
This is the descending process. First, at the beginning of the lowering step, the piercing punch 12 that has entered the upper blade 5 is lowered. Furthermore, the lower blade 6
When the metal plate feed guide 10 descends, the metal plate feed guide 10 separates from the lower surface of the upper blade 5. Then, the parry-like protrusion of the metal plate p pushed out by the breaking punch 12 comes out from the hole of the upper blade 5. At this time, the lowering process of the lower blade 6, that is, the lower die set A* is completed. Immediately before this completion, the metal plate p is sent one step (-feed amount) to the left by the stepping motor Ms. This completes one cycle of operation.

Next, when operating the tip attachment stopper pin 14, that is, when hitting the cutting blade against the tip of the carton a, this time the intermediate attachment stopper pin 13 is kept inactive. Since the end attachment stopper pin 14 is located at the front in the direction of movement of the carton a, the intermediate attachment stopper pin 13 may be left as is. In addition, the mounting positions of the tip attachment stopper pin 14 and the tip attachment stopper main portion 23 in the feeding direction are specified, so they can be attached forward or backward! As shown in FIGS. 24 and 25, the carton a is stopped at the main part 23 of the stopper for attaching the tip, and the carton a is
This mounting operation is similar to the case where the carton a comes into contact with the intermediate mounting stopper pin 13 described above.

〔Effect of the invention〕

The invention of claim 1 is provided with a structure in which a cutting blade is struck against the carton a in the mold die set A0 provided in the main machine frame 1, and the carton a formed in the mold die set A0 is transferred. The carton a is inserted into the flat feed hole 8.
stop sending. A device for attaching a cutting blade to a carton is provided with a stopper pin 13 for intermediate attachment and a stopper main part 23 for attaching the tip with a stopper pin 14 for attaching the tip, and the carton a is brought into contact with only one of the stopper pins 14. Firstly, the same model can be used to attach the cutting blade to the carton a, whether it is at the tip or in the middle.
The mounting position can be changed with one touch, the workability can be greatly improved, and thirdly, the structure can be made simple and inexpensive.

To explain these effects in detail, there have conventionally been two types of mounting positions for the cutting blade on the unfolded plate-shaped carton a: one for mounting at the tip and one for mounting in the middle. Therefore, in order to perform this work with the same model, it is necessary to completely replace a part of the machine, or it is not only necessary to replace the machine but also to save time.
Hammering had the disadvantage that the work efficiency was halved, but in the present invention, a cutting blade is hammered onto the carton a within the mold die set provided in the main machine frame 1.
The feeding of the carton a is stopped within the flat feeding hole 8 through which the carton a formed in the mold die set A0 is transferred. Intermediate mounting stopper pin 13 and tip mounting stopper pin 1
4 and a stopper main part 23 for attaching the tip to the carton so that the carton a comes into contact with only one of them, the stopper pin 13 for intermediate attachment or the tip attachment For example, if the carton a comes into contact with one of the stopper main parts 23 for end attachment with the stopper pin 14 attached, for example, if the carton a comes into contact with the stopper pin 13 for intermediate attachment, the middle part of the carton a in the length direction The cutting blade can be attached to the tip of the carton a when the carton a comes into contact with the main part 23 of the stopper for tip attachment with the per pin 14. This is the same model and is for tip mounting.

These two types, one for intermediate mounting, have become possible for the first time, and their effects are significant.

In addition, the main part 2 of the stopper for attaching the tip with the stopper pin 13 for intermediate attachment and the stopper pin 14 for attaching the tip.
Since the carton a comes into contact with only one side of the carton A, it is ensured that the carton a comes into contact with only one side, and the cutting blade can be attached to the carton a very easily, either at the tip or at an intermediate position, increasing work efficiency. can be dramatically improved.

Furthermore, in the present invention, since the carton a is in contact with either the intermediate attachment stopper pin 13 or the tip attachment stopper main portion 23 with the tip attachment stopper pin 14, no major modification of the machine is required. The structure in which the carton a comes into contact with the intermediate attachment stopper pin 13 is designed to prevent the tip attachment stopper pin 14 from being removed or the lower end of the tip attachment stopper pin 14 from coming into contact with the tip attachment stopper main part 23. On the other hand, in a configuration in which the carton a contacts the tip attachment stopper main portion 23, the tip attachment stopper main portion 23 is advanced from the intermediate attachment stopper pit 13 position. Therefore, if the carton a with cutting blades does not come into contact with the intermediate mounting stopper pin 13 at all when the carton a with the cutting blades is discharged, the intermediate mounting stopper pin 13 Since the configuration can be used as is, it is possible to easily configure the configuration in any case.
As a result, it can be provided at low cost.

Next, in the invention of claim 2, in the mold die set As provided in the main machine frame 1, a cutting blade is provided to strike the carton a. The feeding of the carton a is stopped within the flat feeding hole 8 through which the carton a is transferred. A pair of left and right intermediate attachment stopper pins 13° 13 and a tip attachment stopper main part 23 with a tip attachment stopper pin 14 are provided, and the carton a is brought into contact with only one of these, and the rain intermediate attachment A front and rear adjustment plate that can adjust the stopper pin 13.13 back and forth at the same time, and a stopper pin 13.13 for rain intermediate installation that can independently adjust the left and right sides of the stopper pin 13.13, and that can adjust the stopper pin 13.13 for rain intermediate installation respectively. By using the attached independent front and back adjustment plates 21 and 21 as a cutting blade attachment device to the carton provided on the elevating main plate 17 that can be raised and lowered,
In any case, as an intermediate attachment, it can always be nailed to the carton a very precisely at the desired position.

To explain this in detail, when hitting the cutting blade at an appropriate position in the middle of carton a, the hitting position is
How many centimeters is away from the tip of the carton a, the front and rear adjustment plate 18 is adjusted back and forth and set at a predetermined position, thereby allowing the cutting blade to be struck at a desired position on the carton a. Furthermore, even if the finish of the carton a or the shape of the carton a is not symmetrical, the cutting blade can be cut by adjusting the front and rear independent 11-section plates 21 of at least one of the left and right pairs as appropriate. There is an effect that the cutting blade can be struck extremely accurately at a desired position so that the surfaces all protrude by the same width from the corners of the box-shaped carton a.

Further, the other configurations are the same as the invention of claim 1, and the same effects can be achieved.

Next, in the invention of claim 3, the carton a can be transferred only in one direction in the flat feed hole 8 formed in the mold die set Ao provided in the main machine frame 1, and the carton a can be transferred in only one direction. The carton is equipped with a structure in which a cutting blade is struck against the carton to stop the feeding of the carton a. Intermediate mounting stopper pin 13
and a stopper main part 23 for tip attachment with a stopper hinge 14 for tip attachment, so that the carton comes into contact with only one of these, and the stopper for intermediate attachment is always applied at a predetermined pressure on the rear end side in the transport direction of the carton. By using the device for attaching the cutting blade to the carton, which is equipped with the transfer pressing structure C3 that presses the pin 13 unevenly, firstly, it is possible to always hit the cutting blade at an accurate position at the tip or middle of the carton a. Second, the number of strikes of the cutting blade can be increased.

To explain these effects in detail, the carton a is
The cutting blade is struck in the mold die set A), and the carton A with the cutting blade passes through the mold die set A and is transported in one direction, but when striking the cutting blade, The feeding of the carton a is stopped at the front end in the transport direction by the stopper pin 13 for intermediate attachment or the main part 23 of the stopper for end attachment, and the rear end of the carton a in the transport direction is always pushed toward the stopper with a predetermined pressure. Since the carton a is pressed by the transfer pressing structure C3, even if vibration or the like occurs when hitting the carton a, the carton a will not shift at all in the front and rear direction, and the cutting blade will not be moved at the tip or middle of the carton a. It can be struck at an accurate position (distance L from the end in FIG. 27).

Being able to hit the cutting blade at an accurate location l in this manner has an extremely large effect on attaching the cutting blade to the carton a.

Conventionally, even if a stopper exists and the feed is stopped using this stopper, if the feed amount is increased, depending on the speed, it will inevitably rebound after colliding with the stopper, causing the carton a to return or the cutting blade to be damaged. Due to the vibration etc.
Carton a shifts, and the position of the cutting blade is fixed in the machine, so there is a slight difference in the front and back direction (for example, even if it is large, 1fi to 2 to 3 mm) at the position where the cutting blade hits the carton a. ) A misalignment occurred and L) occurred. This misalignment is caused by the fact that even if you store the wrap in a box-shaped carton a, pull it out, and try to cut it with the cutting blade, the cutting blade may not protrude from the corner. In some cases, the cutting blade had serious defects that made it completely useless.

However, in the present invention, as described above, the cutting blade can be struck at an accurate position on the carton a, so when the carton a is pulled out and cut from the box-shaped carton a containing wrap, etc., the cutting blade is It has the advantage of being able to perform its functions well and cutting reliably with the cutting blade.

In addition, since it is possible to hit at an accurate position in this way, even if the number of hits per unit time is increased and the transfer speed is increased, the intermediate position is always maintained at a predetermined pressure on the rear end side of the carton a in the transport direction. Transfer pressing structure C to the mounting stopper pin 13 side
3, the carton a collides with the intermediate attachment stopper pin 13 or the tip attachment stopper main portion 23.

Or it never rebounds and returns to its original state.

Therefore, it is possible to increase the number of impressions per unit time and improve the efficiency of the impression.

Furthermore, in the present invention, in the mold die set A6,
Since carton a can only be transferred in one direction, carton a to which the cutting blade has not been applied and carton a to which the cutting blade has been applied are always in one direction, and carton a to which the cutting blade has not been applied. The carton a struck by the cutting blade does not cross or collide with each other, and even if the feed amount is increased, extremely orderly feeding is possible.

As described above, the stopping structure of the stopper at the front end of the carton a, the transfer pressing structure C3, and the one-way feed work synergistically, and the cutting blade can be struck onto the carton a at an extremely high speed. It has a revolutionary effect.
