The lid F that is integrally closed by means of can be easily removed from the box body, and at this time, the blade located at the corner in the upper part of the box W or the bag or the like for packaging the article can be cut off at the cutting edge. I try not to cut it. The incision device 1 is capable of supplying the box W onto the transport unit 4 in either a vertically long position or a horizontally long position, but the side where the outer lid M and the inner lid N are superposed, that is, the inner lid. It is advisable to position and supply the side wall having N to the front and rear so as to coincide with the transport direction, and to place and supply it on the transport body 4. In this case, the cutting resistance when the cutters K cut and move in the lateral direction during the cutting operation. It is possible to prevent deformation of the box body W due to the above, and to perform accurate cutting efficiently and satisfactorily while simplifying the overall configuration of the device.

As a result, the cutter unit 6 can easily position and fix the knife-shaped cutter K at an appropriate cutting position simply by operating the mounting screw 95 and adjusting the mounting piece 93 forward and backward. Since the cutter K can be easily attached and detached, there is a feature that the re-grinding work and the exchange of the cutters K having different lengths can be easily performed as shown in FIG.

る方向と略直交する線上に一致させている。In the cutter section 6 having the above-described structure, the relationship between the cutter K and the upper guide roller 80 and the side guide roller 81 is as follows. That is,
The knife-shaped cutter K has a blade edge inclined to the proper cutting angle described above so as to face the folding portion S of the box W within the guide interval (FIGS. 13 and 16), and the upper guide. The center peripheral surfaces of the roller 80 and the side guide roller 81 are
As shown in FIG. 13, the outer lid M (the upper surface of the corner portion) and the side wall (the side surface of the corner portion) of the box body W are provided substantially orthogonally so as to be capable of rolling contact with each other, and the cutting edge of the cutter K is provided on the side of the guide roller 80. The upper guide roller 80 and the side guide roller 81 have substantially the same center of rotation as the cutting edge while being positioned substantially in the middle of the plane orthogonal to the partial guide roller 81. The blades are aligned on a line, and are aligned on a line that is substantially orthogonal to the cutting movement direction of the cutting edge.

ができる等の特徴がある。As a result, when the cutter portion 6 moves in the cutting direction, the upper guide roller 80 is pressed against the outer lid M by the urging force of the spring 65 about the support shaft 62 due to the upper surface and side surface profile cutting structure. Since it rolls along the contour, the cutter support frame 63 can be freely rocked and rotated about the support shaft 62 in the left-right direction of movement along with the movement of the upper guide roller 80 following the outer lid M. The cutting position in the height direction of K can be made constant.
Further, the cutter K has a cutting edge whose upper guide roller 8
Since it is positioned lower than the copying guide 82 within the guide distance between 0 and the side guide roller 81, it swings up and down in the vicinity of the substantially horizontal axis of the support shaft 62, so that the upward cutting angle should be largely changed. There is a feature that a predetermined cutting can be performed with high precision without using it.

る。Further, the side guide roller 81 has the above-described side surface profile cutting structure, and follows the side wall of the box W while pressing the side wall of the box W through the cutter holder 9 slidably supported by the spring 65a with an upward inclination. Because
The side guide roller 81 allows the side guide roller 81 to slide back and forth on the slide shaft 66 in accordance with the situation such as unevenness of the side wall, which makes the cutting position of the cutter K constant in the depth direction and the cutting edge of the cutter K. It has the feature that it can be cut satisfactorily without significantly changing the position.

る。Therefore, since the three members are integrally provided on the cutter support frame 63 by the above arrangement, the upper guide roller 80 and the side guide roller 81 are arranged along the shapes of the upper and side surfaces of the corner portion of the box W. When the contact K is moved by contact, the cutter K also performs the copying operation while keeping the relative position unchanged, so that the cutter K can be smoothly moved in the cutting direction without a large resistance, and the cutting edge of the cutter K can be moved to the corner portion. Since it is possible to accurately follow the shape of and move in the combining direction, there is an advantage that the lid F can be cut to an appropriate cutting depth at a predetermined cutting position.

The slide shaft 66 is supported on the second side so as to be vertically movable in an obliquely downward direction, the cutter support frame 63 is attached and fixed to the upper and lower ends of the slide shaft 66, and the cutter support frame 63 can be copied and operated by the springs 65 and 65a. It is biased, and the biasing operation range is regulated by the stoppers 69, 69a. Then, the slide shaft 66 of the cutter support frame 63.
By installing the guide member 8 and the cutter K with a configuration similar to that described above at the substantially extended end of the cutter support frame 63
It is possible to smoothly perform the left-right rotation and the up-and-down advancing / retreating operation and improve the cutting accuracy by the cutter K.

As shown in FIG. 11 (A), the front cutter portion 6a is first moved rearward through the support base 32 from the standby state of the cutter portion 6 shown in FIG. Set to the cutting standby position of the front side stopped at the cutting depth position. At this time, the cutter K is located on the left side of the box W. Then, substantially simultaneously with this, the left cutter part 6c and the right cutter part 6d, which are on standby on the left and right outer sides of the box W, are moved to the inner side by the operation of the width determining motors 37, 37, as shown in FIG. Aside from this, the blades are moved to a predetermined cutting depth position and stopped in the cutting standby position on both sides, and the supporting base 32a is moved forward while maintaining this position. While performing the cutting for the front cutting distance L, the cutter K of the rear cutter portion 6b is moved to a predetermined cutting depth position and stopped to be in the cutting standby posture of the rear side. At this time, the cutter K is located to the right of the box W.

The front side cutting step in which the inner lid N and the outer lid M are overlapped (cutting of the overlapped lid) is completed, and the front cutter portion 6a is a box W.
It is positioned so as not to interfere with the cutting completion posture of the right cutter portion 6b, which will be described later, by stopping to the outside of the right side separated from. At the same time, at the same time, the rear cutter portion 6b is attached to the support rod 31a.
By cutting and moving to the left along the direction, the rear side cutting step in which the inner lid N and the outer lid M of the box W overlap is completed, and the rear cutter portion 6b is moved to the left of the box W. Stop outward.

浮き上がりを防止しながら安定支持されることになる。At this time, since the front side of the lid portion F of the box body W has already been cut by the front cutter portion 6a, the rigidity of the box body is lost by that amount and the box body W is weakened and easily deformed. With the cutting of the front base of the inner lid N,
Although the outer lids M on both sides are going to be lifted and deformed in the lid opening direction, by cutting the front cutting distance L of the left cutter portion 6c and the right cutter portion 6d, the upper rear sides of the box body W have both sides. Since the cutters K and K are in a state of being supported on both sides due to the cutting being stopped midway (hereinafter referred to as both-side front cutting support), the cutter K will not be deformed or lifted up to be stably supported while being cut. .

行うことができる等の特徴がある。Therefore, when the cutters K of the front cutter portion 6a and the rear cutter portion 6b perform the cutting movement from one side to the other side, the cutting resistance prevents the box W from being displaced or deformed and raised. Thus, the front and rear side edges are cut accurately and smoothly, and the box W is clamped downward by the sandwiching guides 51, 5
Even when the cantilever is supported by 1, the incisions at the upper portions thereof are opposite to each other and simultaneously move in opposite directions to cut (hereinafter referred to as opposed cutting) a front cutter portion 6a and a rear cutter portion 6
Since it is performed by b, the force in the pushing-down direction due to the resistance at the time of cutting is canceled out, the deformation can be prevented while the stable support of the box W is achieved, and the cutting can be performed quickly with high accuracy. There is a feature of.

Since the front side and the rear side of the lid part F of FIG. 2 have already been cut by the front cutter part 6a and the rear cutter part 6b, the rigidity of the box body is lost by that amount, and the lid part F becomes weak and easily deformed. By performing the initial cutting for the front cutting distance L in advance and being in the next continuous cutting standby state in the same cutting posture, a large cutting resistance is generated when the cutting is started again, or the cutting start position is increased. It is possible to accurately prevent the deviation from occurring, and the non-overlapping lid side cutting on both sides of the box body W is smoothly performed as it is over the entire length.

る。Next, when the cutting process of the lid part F of the box W as described above is completed, the cutting part 3 raises each cutter part 6 in the cutting completion posture, and moves each cutter part 6 to the original cutting standby posture. At about the same time, the stop guides 50 and 52 of the positioning unit 5 move backward from the transport surface, and the transport unit 4 is driven to discharge and transport the incised box W forward while transporting the next position. The box W is conveyed to the positioning unit 5, and the next box W is positioned and fixed again by the protrusion of the stop guide 50 and the pinching operation of the pinching guide 51, and the above-described incision process is repeated. Can be efficiently and continuously performed. Further, since the box W that has been subjected to the incision work is in a state in which the lid part F whose entire circumference is cut is placed on the box body, the lid part F can be easily removed. Can be easily taken out.

行い易くすることができるようにしている。When performing the box incision work as described above, the incision device (elevation work device) 1 divides the weight 7 corresponding to the weight of the incision part (elevation work part) 3 into a plurality of columns 21. Since it is supported so that it can move up and down,
1 supports a plurality of weights 7 in a divided manner also as an elevating / lowering support member for the weights 7, and the divided individual weights 7 can have a small weight and can be made small in size, and the production thereof and the assembling to the column 21 are easy. Can be Further, since the miniaturized weights 7 can be compactly assembled and smoothly moved up and down for each of the columns 21, the weight 7 can be moved up and down between the columns 21 as in the conventional one in which a long weight 7 is elevated between the columns 21. There is a feature that the space between the support columns 21 can be largely opened without making a space and obstructing the field of view, and that this part can be effectively used. In this embodiment, as shown in FIG. 3, a door made of a transparent member is provided between the front and rear columns 21 so as to be opened and closed.
The work status of the incision 3 and the maintenance work can be facilitated.

を図ることができる等の特徴がある。The present invention has the following effects due to the weight structure of the lifting work device as described above. (1) A hoisting work unit is provided to be able to go up and down on a machine body in which a plurality of columns are connected by a horizontal frame, and the hoisting work unit is provided on one side and the other side of a tight member wound around a hoisting drive wheel for forward and reverse rotation driving. And a lifting work device in which weights are connected to correspond to the weight of the lifting work part, the weight is divided into a plurality of columns so that the weight is supported so that the weight can be lifted. Since the individual weights divided into 2 are small in weight and can be miniaturized, the manufacture thereof and the assembling to the support can be simplified. Also, since the miniaturized weights can be assembled compactly for each column and can be raised and lowered smoothly, the space between the columns does not have to be a lifting space for the weight, as in the case of raising and lowering a long weight between the columns. The feature is that the columns can be widely opened, and this part can be effectively used.
