Description

[Detailed description of the invention] Industrial field of application This invention can be used to create uneven molded bodies made of synthetic resin, rubber, wood, paper, metal, etc. by compression molding, vacuum forming, pressure forming, etc. The present invention relates to a cut object carrying-out device that cuts pieces using a cutting device and automatically carries them out to a predetermined position outside the device.

2. Description of the Related Art A molded article formed by compression molding, vacuum forming, pressure forming, etc. is sent to a cutting device, and is cut by a cutting die and a blade die of the device. The cut object existing on the cutting die is lifted upward by a pin protruding from the bottom of the die, either manually or mechanically.
By pushing it sideways, it fell outside the cutting machine.

Problems that the invention aims to solve: Conventional manual methods not only increase the number of steps for the worker, but also pose a danger as parts of the body enter the cutting device. The work was particularly difficult. Furthermore, even when the cut pieces are mechanically dropped out of the cutting device, it is necessary for the worker to sort the fallen cut pieces, stack them, or transport them to the next process.

Means for Solving the Problems The cut object carrying device of this invention has a suction surface that follows the open surface shape of at least the effective cut objects of a plurality of cut objects that have been cut and are present on the mold surface of the lower cutting mold,
The effective cut object and the ineffective cut object are adsorbed by a suction cup having a built-in function of adsorbing them separately, and then moved to separate predetermined positions outside the cutting device and released.

In addition, the function of adsorbing the cut object is due to the pressure difference acting on both sides of the cut object, the function of adsorbing the cut object is due to the action of magnetic force, and the function of attracting the cut object is due to the pressure difference and magnetic force acting on both sides of the cut object. It may also be due to action.

Function Since the cut body carrying out device of this invention is configured as described above, there is no need to insert a part of the body into the cutting device, and there is no need to manually align and stack the cut bodies taken out. Further, movement to the next process is automatically performed.

Furthermore, since the effective shredded bodies that become products of shredded bodies and the ineffective shredded bodies that are recycled as scrap can be moved to different positions or stacked, the number of man-hours required to separate them can be reduced.

Embodiment The details of the cut body conveyance device of this invention will be explained with reference to the drawings.

Fig. 1 is a side view schematically showing a cut object carrying device partially in cross section, in which the upper cutting die 1 and the lower cutting die 2 are opened after cutting has been completed, and a suction cup is placed between both dies 1 and 2. 6 is inserted.

The upper cutting die 1 and the lower cutting die 2 are fixed to a movable platen and a fixed platen of a cutting device (not shown), such as a compression press, via mounting plates 3 and 4, respectively.
Both molds 1 and 2 are clamped or opened by the action of hydraulic pressure. Note that the upper cutting die 1 has a cutting blade 1a having a cutting edge that follows the shape to be cut, and the lower cutting die 2 has a die surface that follows the shape of the molded product to be cut, and the cutting blade 1a is provided at the cutting position. Concavity 2a that escapes the cutting edge of
is provided.

In the cutting process, first, while the suction cup 6 is retreating to the outside of the cutting device in the right direction, the molded object to be cut is inserted between the molds 1 and 2 and the molds are clamped, and an effective cut object 5 is formed.
and an ineffective cut body 5a. Next, after opening both molds 1 and 2, attach the suction cup 6 to both molds 1 and 2.
6a is advanced in the meantime and then lowered onto the cutting bodies 5, 5a. After adsorbing the cut pieces 5, 5a to the suction cup 6, they are moved upward and then placed at a predetermined position 6b.
When the suction action of the effective cut pieces 5 is released, the effective cut pieces 5 are stacked on the pallet 16 as shown in 15, and the suction cup 6 is similarly moved to another predetermined position 6c to remove the ineffective cut pieces. When the adsorption action of the part 5a is released, the ineffective cut pieces 5a also fall into the pallet 18.
They can be stacked like 17 on top. Incidentally, when the suction cup 6 is retreated to the outside of the cutting device, the molded article to be cut next is inserted between the molds 1 and 2, and the next cutting cycle is started.

The suction cup 6 of the cut material carrying device of this invention has a second
As shown in the figure, it has a suction surface 8 that follows the shape of the open surface 7 of the effective cut object 5 and the ineffective cut object 5a,
The suction surface 8 of the suction cup 6 is provided with a large number of exhaust holes 22 corresponding to the active cut body 5 surface portion and a large number of exhaust holes 27 corresponding to the ineffective cut body 5a surface portion.
The exhaust holes 22 and 27 are connected to a vacuum pump via hollow chambers 21 and 25 of separate systems, exhaust pipes 23 and 26, and valves (not shown), and both systems are not shown. The cutting bodies 5, 5a can be cut independently by opening and closing the valve.
It has a structure that allows each part to be adsorbed and released separately.

After the cutting of the molded product is completed and the upper cutting die 1 opens upward, the suction cup 6 is inserted between the two dies 1 and 2, and then suction is started while sucking air from the exhaust holes 22 and 27. The board 6 is lowered until the suction surface 8 comes into contact with the open surface 7 of the cut pieces 5, 5a. When the suction surface 8 and the open surface 7 come into contact, a pressure difference is generated on both sides of the cut bodies 5, 5a due to the exhaust action of the suction cup 6.
The cut bodies 5 and 5a are sucked by a suction cup 6. At this time, an effective cut piece 5 with unevenness and an ineffective cut piece 5
Since a is brought into contact with the suction surface 8 of the suction cup 6 over its entire surface, even if the cut objects 5, 5a are soft and thin, the suction surface 8 is in contact with the suction surface 8 of the suction cup 6 when it is separated from the lower cutting mold 2 and during movement. It will not hang down and stretch from 8, and will not cause wrinkles in the cut pieces 5, 5a.

Note that when the cut pieces 5, 5a are attracted to the suction surface 8 and the suction cup 6 rises, if they are in close contact with the mold surface of the lower cutting mold 2 and are difficult to release, a Either push up the cut pieces 5 from the mold surface with an ejector pin that is not attached to the mold surface, and raise the cut pieces 5, 5a slightly from the mold surface, or create a number of narrow grooves (not shown) communicating with the outside in the mold surface of the lower cutting mold. It is a good idea to set this up.

Since the suction cup 6 is fixed to the piston rod 10 via the connecting rod 9, when the piston rod 10 moves up and down in the direction of the arrow due to the action of the cylinder 11, the suction cup 6 moves up and down in conjunction with this movement. Further, the cylinder 11 is fixed to a horizontal bar 12 by a known device (not shown) that can move forward and backward in the lateral direction and can be stopped at a predetermined position.

The suction cup 6 that has sucked the cut objects 5, 5a is moved laterally by the action of the cylinder 11 to a position where it does not come into contact with the lower cutting die 2, and then the suction cup 6 is moved laterally until it reaches the position 6b outside the cutting device. Move the rod 12 to the right. Therefore, the exhaust hole 2 of the suction cup 6
When the exhaust from 2 is stopped, the effective cut pieces 5 are released from the suction cup 6 and stacked on the pallet 16 like 15. Similarly, after moving the suction cup 6 to the position 6c, the exhaust from the exhaust hole 27 is stopped and the ineffective cut pieces 5a are opened, so that they are separated and stacked on the pallet 18 as shown in 17. It can also be dropped directly onto a conveyor belt and sent to a scrap collection site or recycling process.

As shown in FIG. 3, on the suction surface 8 of the suction cup 6,
If a cushion sheet 24 made of silicone rubber or the like is pasted and through holes communicating with the exhaust holes 22 and 27 are made, the open surfaces 7 of the cut pieces 5 and 5a and the suction surface 8 of the suction cup 6 will come into close contact with each other. This improves the adsorption power.

When the cut bodies 5, 5a are made of a magnetized material such as iron, an electromagnet 3 is attached to a portion of the suction surface 8 of the suction cup 6 corresponding to the ineffective cut body 5a, as shown in FIG.
5 is buried, the ineffective shredded body 5a can be attracted by the action of magnetic force, and the effective shredded body 5 can be attracted to the corresponding attraction surface 8 part by the pressure difference applied on both sides in the above-mentioned method. I can do it. Then, when the exhaust is stopped at a predetermined position or the magnetic field is extinguished by cutting off the current, the cut pieces 5, 5a are released, fall down by gravity, and are stacked.

Of course, it is also possible to attract each of the cut bodies 5 and 5a by magnetic force and move them to their respective predetermined positions, and it is also possible to attract each of them by a combination of magnetic force and pressure difference. , 5a.

In addition, only the effective cutting body 5 is cut into the lower cutting type 2 using the suction cup 6.
The ineffective cut pieces 5a are conveyed to a predetermined position by a pressure difference or magnetic force, and the ineffective cut pieces 5a are made to protrude from the lower cutting die 2 by the action of an ejecting pin provided on the lower cutting die 2, and are then removed from the cutting machine by a removal lever onto the conveyor outside the cutting device. It may be dropped. Therefore, in this case, the suction surface 8 of the suction cup 6 needs to follow the open surface shape 7 of the suction cup 6, since it is only necessary to suction the effective cut material 5.

In the above embodiment, the molded body is placed inside the effective cut body 5.
Although we have described the case where the cut pieces are cut into external ineffective cut pieces 5a and each is carried out to a predetermined position, there are also cases where the cut pieces are divided into only valid cut pieces, and in order to ensure separation from the valid cut pieces 5, 2 ineffective cut pieces 5a
In some cases, the paper may be cut into smaller pieces.

The device for transporting cut objects of this invention can be used not only to transport molded objects manufactured by compression molding, but also to transport molded objects manufactured by vacuum forming and pressure forming out of the cutting device after cutting, and to transport molded objects manufactured by vacuum forming and pressure forming to the outside of the cutting device. It can also be used for transportation.

As a further embodiment, as shown in FIG. 5, the cylinder 11 can be rotated by a predetermined angle by the action of a servo motor 40 installed on the upper beam, and the tip of the piston rod 10 of the cylinder 11 can be rotated by a predetermined angle. Even if a traversing mechanism 41 is provided which can move the connecting rod 9 in the left-right direction as shown by the arrow, it is possible to move the cutting bodies 5, 5a out of the apparatus and open the apparatus.

That is, from the position shown in FIG. 5, the cylinder 1 is
1 to lower the suction cup 6 until its suction surface 8 contacts the open surface 7 of the cut object 5,
5a is adsorbed. Next, when the cylinder 11 is actuated and the piston dot 10 is pushed in, the suction cup 6 rises while sucking the cut pieces 5, 5a. When the traverse mechanism 41 is operated to move the suction cup 6 out of the cutting device, and the servo motor 40 is then operated, the cylinder 11 rotates and the connecting rod 9 rotates, so it is fixed to one end of the connecting rod 9. The suction cup 6 can be moved to a predetermined position outside the cutting device without coming into contact with the cutting device. Therefore, the cut pieces 5, 5a sucked by the suction cup 6 are placed at predetermined positions outside the cutting device, for example, on the surface of the second molding die, on the cutting die, the effective cut pieces 5 are placed on the pallet 16, and the ineffective cut pieces are placed on the pallet 16. 5a
can be moved onto a pallet 18 or dropped directly onto a conveyor belt to be sent to a scrapyard or recycling process.

Effects Since the device for discharging cut objects of this invention is configured as described above, there is no need to insert a part of the body into the cutting device, and the cut objects taken out can be automatically arranged and stacked without having to be inputted. will be implemented.

Furthermore, since the effective cut pieces and the ineffective cut pieces can be stacked at different positions, the number of man-hours required to separate them can be reduced. Generally, the cut surfaces of the effective and ineffective cut bodies are sharp, but according to this invention, no human hands are required to carry out the cut bodies, so it is safe without injuring hands or arms. Furthermore, if this device is combined with a known sheet-like molded material automatic in-mold mounting device, automatic trimming can be performed subsequent to automatic molding.

Since the effective cut object contacts the suction surface of the suction cup over its entire surface, even if the effective cut object is soft with large undulations and thin, it will not touch the suction surface when it leaves the lower cutting die and during movement. It does not sag or stretch or cause wrinkles in the cut material. Moreover, since the sheets are stacked correctly in a predetermined position, beautiful cut pieces can be obtained without any scratches.
