[0006]

As a work cutting / distributing system for dividing a large work into a plurality of medium works as described above and further dividing a medium work into a plurality of small works, a plurality of large work places can be provided. A cutting unit at the previous stage that cuts the medium to be cut one by one and cuts the medium-sized work one by one,
There is a system in which a plurality of locations to be cut of a medium-sized work piece cut out from the cutting unit at the preceding stage are sequentially cut to cut out one small work piece at a time and a cutting unit at the subsequent stage is connected to the system. In the same system, the cutting unit at the front stage and the cutting unit at the rear stage have almost the same work cutting speed, and both of them repeatedly cut the work continuously. Also, the larger the number of cut parts of the medium-sized work supplied from the cutting unit of the previous stage to the cutting unit of the latter stage, the more the cutting part of the latter stage cuts the first cut part of the medium-sized work and then the last cut part. The time period until the end of cutting the cutting point becomes longer. This time zone is a time zone in which a new medium-sized work cannot be conveyed from the cutting unit in the previous stage to the cutting unit in the subsequent stage, and the cutting unit in the preceding stage interrupts the work cutting operation and waits for a command signal for cutting the work. It becomes the time zone of. The work waiting time generated in the cutting unit at the preceding stage becomes longer as the number of cut portions of the medium-sized work increases, and the productivity of the work cutting / distributing system as a whole is lowered.

It is an object of the present invention to provide a work cutting / distributing system with improved productivity in a work cutting process for dividing a work such as a resin sheet into a plurality of stages.

[0008]

In order to achieve the above object, the present invention provides a pre-cutting unit that cuts a work piece into pieces and cuts the work piece, and a single work piece cut out from the pre-cutting unit piece. In a work cutting distribution system that has a post-cutting unit that cuts out by cutting and a work carrying unit that carries the work cut out from the pre-cutting unit to the post-cutting unit one by one, in the work carrying unit, the work carrying means sends the work from the previous cutting unit to the post-cutting unit. A transfer destination changing means for changing the transfer destination of the work being transferred to the cutting unit is provided, and the work transfer destination changed by this transfer destination changing means has the same function as the post-cutting unit and the post-cutting unit of another unit. It is characterized by connecting.

The post-stage cutting unit according to the present invention includes an existing post-stage cutting unit connected to the existing pre-stage cutting unit, and an additional post-stage cutting unit connected via the transfer destination changing unit of the work transfer unit. The post-cutting unit for the expansion is removably added to the existing pre-cutting unit. A single work is continuously cut out from the front cutting unit of a single unit, and is selected and conveyed to any one of the plurality of rear cutting units. As the transfer destination changing unit of the work transfer unit, a rotary type delivery mechanism that changes the transfer direction by rotating the work at a fixed position, a slide movement type distribution mechanism that slides the work back and forth, and right and left are applied.

The selection of the work transfer destination by the transfer destination changing means in the above invention is performed based on the operating conditions of all the plurality of subsequent cutting units (the invention of claim 2). That is, the plurality of post-stage cutting units have various operating states such as a unit in a state in which the work has begun to be cut, a unit in which the cutting of the work is almost completed, and a unit in which the cutting of the work is completed and is in an empty state. Therefore, a post-stage cutting unit in an operating state in which cutting can be started as soon as it is supplied with a work, such as a unit in which cutting of a work is about to be completed or a unit in an empty state after cutting is completed, is selected as a work transfer destination. By doing so, the waiting time for the work of the pre-stage cutting unit is eliminated, or it is greatly shortened, and it becomes easy to improve the productivity of the work cutting.

According to a third aspect of the present invention, the front stage cutting unit and / or the rear stage cutting unit includes a pair of cutting blades for simultaneously pressing both front and back surfaces of a work to be cut at one place. It is characterized by having.

That is, a general work cutting device for cutting a work with one cutting blade may be used for the front cutting unit and the rear cutting unit, but the work is clamped by a pair of upper and lower cutting blades and press-cut. By doing so, the cut surface of the work will be high quality with less burrs and burrs,
The quality of the subdivided work is improved. This method of press cutting a work with a pair of cutting blades applies the blade tips of a pair of cutting blades to the front and back surfaces of the work to be cut at one location at the same time, from the front and back to the center point in the thickness direction of the work to be cut. Insert it all at once to divide the cut part, or insert a pair of cutting blades from the front and back surfaces of the cut part to near the center point in the thickness direction and cut the center part of the cut part in the thickness direction. It is effective to leave it without pressing, and immediately after that, press-cut the approximately central portion left with only one cutting blade.

A pair of support plates 56 is arranged in front of and behind one cutting blade 41, and a work retainer 57 is connected below each support plate 56 via a spring member 58.

When the servomotor 52 of the first drive mechanism 50 rotates the ball screw 51 in the forward and reverse directions, the integral body of the nut member 53 and the guide member 54 is guided by the guide rail 55 to move up and down, and the integrated body with the guide member 54. The support plate 56 and the cutting blade 41 move up and down. The cut portion 2a of the horizontal large work 1a is arranged directly below the cutting blade 41, and press-cut by the descending cutting blade 41. As shown in FIG. 4, the work retainer 57 attached to the lower surface side of the support plate 56 is divided into a plurality of pieces in the width direction of the large work 1a, for example, three pieces,
Each of them is adapted to independently press near the front and rear of the linearly cut portion 2a in the width direction of the large work 1a.

The second drive mechanism 60 has a ball screw 61 for moving the cutting blade 42 up and down, and a servo motor 62 for rotating the ball screw 61 forward and backward. The servo motor 62 is placed horizontally on the lower base 71 of the frame 70. Fixed,
The ball screw 61 is coaxially connected to the horizontal rotary drive shaft of the ball screw 61. The ball screw 61 is horizontally arranged at a fixed position on the lower base 71, and a tip portion of the ball screw 61 extends right below the first drive mechanism 50, and a nut member 63 is screwed to the tip portion.

The horizontal cutting blade 42 moves up and down near the work receiver 75 as shown in FIG. The upper surface of the work receiver 75 is a horizontal surface, and this upper surface is divided into two parts by the central slit portion, and the upward cutting edge of the cutting blade 42 moves up and down in the slit portion. The upper surface of the work receiver 75 is at a fixed position, and the work holder 57 moves up and down above the upper surface. When the work clamp 57 descends, the large work 1 is placed on the work receiver 75.
By pressing a, the large workpiece 1a is cut at one place 2
Temporarily fixing the front and rear periphery of a, a pair of upper and lower cutting blades 41,
The posture of the cut portion 2a immediately before being cut by 2 is stabilized, and the cutting operation of the cut portion 2a by the pair of cutting blades 41 and 42 is always stable.

First, as shown in FIG. 5 (A), a pair of upper and lower cutting blades 4 are provided on both front and back surfaces of a horizontal large workpiece 1a at a fixed position.
1 and 42 are moved closer to each other, and the cutting blades 41 and 42 simultaneously press-cut one cut portion 2a of the work 1a from above and below. This press cutting is performed by leaving a substantially central portion n of the cut portion 2a in the work thickness direction.
By simultaneously press cutting the cut portion 2a of the work 1a from both the front and back sides thereof with a pair of cutting blades 41, 42, the pressing force of the both cutting blades 41, 42 on the cut portion 2a is offset, and the cut portion 2a is cut. The simultaneous pressing from above and below the location 2a is always performed well.

Next, as shown in FIG. 5 (B), the upper cutting blade 41 is left on the work 1a and the lower cutting blade 4 is left.
2 is lowered to separate from the work 1a. By this detachment, a cutting groove 43 having an inverted V-shaped cross section, in which the cutting edge of the cutting blade 42 is removed, opens on the back surface of the cut portion 2a of the work 1a. Cutting blade 4
When the cutting blade 42 is lowered, or when the cutting blade 42 is lowered to the lower limit position, the upper cutting blade 41 is further lowered as shown in FIG. Press cut. The blade tip of the cutting blade 41 is slightly projected to the ceiling portion of the cutting groove 43 on the back surface of the work, and the substantially central portion n is completely press-cut. After that, FIG.
As shown in (D), the cutting blade 41 is raised to the original upper limit position.

On the cut surface of the work 1a after press cutting shown in FIG. 5 (D), a damaged portion such as burrs and burrs is unlikely to occur. That is, since the insertion amount when press cutting the work 1a of each of the pair of upper and lower cutting blades 41 and 42 is less than half of the insertion amount when cutting the work with one cutting blade, Burrs and burrs are less likely to occur on the surface to be cut, and even if they occur, the amount is extremely small or minute. Further, even if burrs or burrs are generated on the cut surface of the work 1a,
These burrs and burrs do not appear as damaged portions on the front surface and the back surface of the work 1a and do not impair the quality of the work. It has been proved that such a work is effectively exhibited in a thin resin sheet having a thickness of about 1.5 mm.
Further, when a thin work such as a resin sheet is press-cut with a pair of cutting blades to an intermediate point in the work thickness direction,
Although it is necessary to control the vertical stroke amount of each cutting blade with extremely high precision, this control can be easily executed by a combination of a ball screw and a servo motor.

Further, as shown in FIG. 3, the upper and lower drive mechanisms 5
By making the axial directions of the ball screws 51 and 61 of 0 and 60 orthogonal to each other, the overall height of the work cutting device can be set small, and the miniaturization of the entire device can be facilitated.

Next, the work cutting / distributing system of the second embodiment shown in FIG. 6 will be described. This is provided for each of a pair of rotary transfer destination changing means 30c arranged on both sides of the reciprocating transfer means 30a. It is configured by connecting three post-stage cutting units 20. One rotary transfer destination changing means 30
Three units of the latter stage cutting units 20 are radially connected to c at intervals of 90 °. The transfer destination changing means 30c rotates the pair of parallel endless belts 90 ° in the plus direction and the minus direction to rotate the medium work 1b carried in from the reciprocating transfer means 30a to any one of the three post-stage cutting units 20.
Transport to unit.

In the work cutting / distributing system shown in the third embodiment of FIG. 7, the transfer destination changing means 30c has a sliding movement type distributing structure. For example, one reciprocating transfer means 30a is installed on a horizontal slide base 31 so as to be movable back and forth intermittently, and the reciprocating transfer means 30 of the slide base 31 is moved.
The post-stage cutting unit 20 is connected to the three sides where a stops. In this case, when it is necessary to further add the post-stage cutting unit 20, the slide base 31 is extended, and the post-stage cutting unit is added to the extended portion.

[0034]

As in the present invention, the transfer destination changing means provided in the work transfer means for transferring the work from the upstream cutting unit to the downstream cutting unit is connected to the downstream cutting unit of another unit having the same function as the downstream cutting unit. By doing so, it is easy to add the post-stage cutting unit, and by adding the post-stage cutting unit, the work that is continuously cut by continuously operating the pre-stage cutting unit is sequentially output to one of the subsequent post-stage cutting units. Therefore, the work waiting time of the preceding cutting unit can be eliminated or significantly shortened, and the productivity of the entire work cutting and distribution system can be improved.

Further, the pre-cutting unit and the post-cutting unit are configured to simultaneously press-cut a work with a pair of cutting blades, so that the quality of the cut surface of the work can be improved and a large size work can be repeated. The quality and commercial value of small-sized work pieces that have been cut and subdivided are improved.
