<Explanation of the gist> The invention of this application is an invention relating to a quantity dividing device having a workpiece transfer device for conveying a plate-shaped workpiece formed by a press or the like. A four-contact bar that is extended and guides four points on the circumference of a dish-shaped workpiece has a bent lower part that is curved and directed downward, and a workpiece transfer amount detection device is faced to the bent lower part, and ,
The lower end of the bent descending section is laterally extended and linked to a separator having a pair of opposing screws, and the workpiece transfer amount detection device controls the screws to charge and suspend the workpieces in the bent descending section. Further, the separator is provided with a trough that slopes forward and upward, and an actuator is provided above the MU Gf r
Further, a rod such as a piston of the actuator is movable forward and backward with respect to the tip between the screws, and a shutter is attached to the tip of the actuator so that it can be freely intervened and retracted. This invention relates to a quantity dividing device for plate-shaped workpieces, which is electrically linked to a facing counter.

<Prior Art> As is well known, in the past, plate-shaped workpieces such as soft drink lids pressed from a molding machine were manually divided into a predetermined number of sheets and packed.

<Problems with the Prior Art> Therefore, not only does this have the disadvantage of increasing costs, but it also has the disadvantage of poor workability and inefficiency.

Further, the number of divided sheets is inaccurate, and skill is required to always divide the number of sheets into a constant number, which has the drawback of interfering with subsequent processes.

<Object of the invention> The object of the invention of this application is to solve the problem of dividing the number of plate-shaped workpieces based on the above-mentioned prior art as a technical problem to be solved, and to automatically determine the quantity and divide it. It is an object of the present invention to provide an excellent plate-shaped work piece dividing device that improves work efficiency, reduces costs, and eliminates the need for skill, thereby benefiting the field of automatic machine utilization in the parts manufacturing industry. It is something to do.

3- <Structure of the Invention> In accordance with the above-mentioned object, the structure of the present invention, which deviates from the scope of the above-mentioned claims, is that in order to solve the above-mentioned problems, a plate-shaped workpiece that is continuously press-molded from a molding machine is After being sent to a workpiece transfer device connected to the workpiece transfer device, the workpiece is fed to a four-contact bar led out from the workpiece transfer device, passes through a curved downward-oriented bending lower log portion, and reaches the lower end. A separator having a pair of opposing screws extending laterally from the part is supplied by the amount of plate-shaped workpieces accumulated at the bending and descending part, and the plate-shaped workpieces are held in an upright position by the screws. During the separation and transfer, a counter accumulates the number of sheets transferred to the separator, and when a predetermined number is reached, an actuator rod is advanced from the front to the upper tip between the screws, and the actuator rod is attached to the tip of the rod. When the shutter intervenes at the tip between the screws, the rod then retreats, and the dish-shaped workpieces are pushed out and gathered together without being tilted forward to the upwardly inclined trough at the set angle, that is, while maintaining the standing posture. , On the other hand, the amount of scraping (of the dish-shaped workpiece) is determined by the workpiece transfer amount detection device facing the bending and descending section of the four-contact bar controlling the scraping operation and adjusting the charging of the workpiece in the bending and descending section. This was achieved by taking technical measures to achieve this goal.

<Configuration of Embodiment> Next, an embodiment of the invention of this application will be described as follows based on the drawings.

In the embodiment shown in FIGS. 1 to 8, numeral 1 denotes a quantity dividing device for plate-shaped workpieces, which constitutes the gist of the invention of this application, and a four-contact bar connected to a well-known press forming machine 2 via a chute 3. 4 are four bars 4' having a circular cross section as shown in FIG.

Further, the work transfer device 6 interposed between the bars 4', 4'... is faced from both sides as shown in Fig. 3.4.
The upper and lower conveyor bells 1 to 7.7 that hold the dish-shaped workpiece 5 are wound around a tension pulley 8, a drive pulley 9 linked to a motor (not shown), and an idler pulley 10 so that they can rotate synchronously in the λj direction. From there, the four-contact par 4 curves into a right-angled downward-oriented bending descending part 11.
It has been extended to the right.

In addition, the workpiece transfer detection device 13 facing the upper corner 12 of the bending and descending portion 11 is arranged in a direction normal to the − part of the corner 12, as shown in Fig. 58.51). The photosensor 14 is connected to a solenoid (not shown) linked to a tension pulley 22, 22 of the separator 15, which will be described later, and is connected to a solenoid (not shown) connected to a tension pulley 22, 22 of the separator 15, which will be described later. The rotational speed of the separator is controlled by keeping the amount of the separator constant.

On the other hand, the four-contact bar 4 extends upwardly from the downwardly extending end of the bent emergency first part 11 at an elevation angle O (θ-15° to 30°), and its tip is connected to the separator 15. ing.

As shown in FIG. 6.7, the lever lever 15 is mounted on a shaft 18.18' that is supported on the base 16 through bearings 17. 19 and 19' have screw grooves 20 and 20' for transferring the dish-shaped workpiece 5 that rotates synchronously in the same direction, and are arranged at the same angle of inclination as the four-contact bar 4 at the end of the bent descending part 11, and The above shaft 18, 18' is the pulley 21
．． 21', through a tension pulley 22, 22' linked to a solenoid connected to the sensor 14, and a pulley 24. 24' to rotate the screws 19 and 19' in the same direction synchronously.

On the other hand, in FIG. 1, the tip 15' of the separator 15 is
At the front end of the trough 25, which has its rear end facing and has the same elevation angle θ as the above-mentioned elevation angle θ, a damper 26 is rotatable via unillustrated springs.
It is linked so that it can be restored after descent.

Further, an air cylinder 28 as an actuator is provided above the damper 2G and is fixed to the frame 27 of the device, and its rod 29 is connected to the screw 19, 19'.
Above the gap, the screw 19.19' can be moved forward and backward along the screw 19, and a solenoid 30 is provided at the tip of the screw as shown in FIG. The closing shutter 31 is connected to the screw 1.
9.19' It is fixedly mounted with a shaft at a right angle facing between.

In addition, 33 is a bath.

In front of the protruding end of the rod 29, a counter 33 for measuring the number of passages of the dish-shaped workpiece 5 is installed on the screw 1.
9.19', and the counter 33 is connected to the air cylinder 28 through a predetermined control device (not shown) having a relay (not shown), a timer relay cumulative calculation device, etc., and sets them. It is controlled by the cumulative number.

<Effects of the Embodiment> In the above configuration, the plate-shaped workpiece 5 discharged from the continuously operating press molding machine 2 is supplied to the workpiece transfer device 6 via the contact bar 4 from 3 to 4 to the sheet 1.

Incidentally, since the dish-shaped work 5 is continuously discharged from the press molding machine 2, the preceding dish-shaped work 5 is stored in the four-contact bar 4 in an orderly manner. After the workpiece 5 is discharged, the workpiece 8 is placed in an upright position continuously on the back side of the preceding plate-shaped workpiece 5.

The plate-shaped workpiece 5 fed to the workpiece transfer device 6 is held around the belt 7.7', and the belt i-
7', 7' is forwarded by the rotational force, and the preceding plate-shaped workpiece 5
are sequentially pressed, guided by the four-contact bar 4, passing through its corner portion 12 and bent descending portion 11, and supplied from its lower end to the separator 15, and pressed against the end of the separator 15 with a constant pressure. It will be done.

Since the screws 19 and 19' of the separator 15 are synchronously rotated in the same direction by one motor M1, the plate-shaped workpiece 5 is meshed with the screw grooves 20 and 20' of the screws 19 and 19'. The machine is moved forward in an upright position.

Therefore, the dish-shaped workpiece 5 has the screw groove 20.
It is separated at every pitch of 20' and transported sequentially, and discharged and accumulated from the front end to the front stage 1 to the rough 25.

During that time, the transferred quantity is detected and accumulated by the counter 33.

When the transfer quantity of the plate-shaped workpieces 5 reaches the set number and is controlled, the detection open side signal from the counter 33 causes the air cylinder 28 to protrude and operate the [1] cylinder 20 via the control device. Next, the solenoid 30 at the tip is activated by the operation of the relay, and the shutter 31 is lowered and closed, thereby closing the tip 15 between the screws 19 and 19'.
', and then the rod 29 is moved back.

Therefore, a predetermined number of the plate-shaped workpieces 5 is placed at once from the trough 25 onto the damper 26, and the damper 26
6 rotates downward and discharges the lff1-shaped workpiece 5 into a container (not shown).

Then, the solenoid ``30'' opens and the shutter 31 opens ``1''.
The air cylinder 27 extends the rod 29 and returns to its original position.

Meanwhile, since the trough 25 is tilted at the set angle θ (10 directions), the plate-like workpiece 5 is not tipped forward, maintains its upright position, and is smoothly transferred to the damper 26. It will be done.

On the other hand, the supply pressure of the plate-shaped workpiece 5 to the separator 15 is increased by
This is caused by the amount of charge in the molding machine 2.
If the transfer amount of the plate-shaped workpiece 5 from the workpiece moving device 6 unexpectedly decreases due to a change in the amount of forming, etc., the pressing force of the plate-shaped workpiece 5 at the corner 12 decreases, and the plate-shaped workpiece 5 51) Bars 4', 4' of inner corner 12 as shown
bar 4' of the outer corner 12,
Move away from 4'.

The photo sensor 14 measures the distance between the plate-shaped workpiece 5 and the outer bars 4', 4', and detects when the distance is equal to or larger than a constant l11+/x.

Then, bells 1 to 23.23' of the separator 15
The solenoid that operates the tension pulley 22, 22' which is in pressure contact with the bell 1-23, 23' is returned to its original state, and the bell 1 to 23, 23' is rotated freely, and the screw 19, 19' is stopped from rotating, and the plate in the bending descending part 11 is stopped. Adjust the filling level of the shaped workpiece 5 to a certain amount or more.

Therefore, the plate-shaped workpiece 5 is always faced to the separator 15 with a constant supply pressure and a constant posture.

On the other hand, when the transfer amount of the plate-shaped workpiece 5 from the workpiece transfer device 6 increases, the plate-shaped workpiece 5 is pressed against the outer bars 4', 4' of the corner part 12, as shown in FIG. 12, and the photo sensor 1
3 detects this and restarts the operation of the screws 19 and 19'.

<Other Embodiments> In the embodiment shown in FIG. From the pressing spring 35.
35..., facing the shoes 36 and 36, and corner 1
The plate-shaped work 5 descended from the work transfer device 6. When the amount of nigiri transferred decreases and the amount of feeding of the plate-shaped work 5 to the bending descending section 11 decreases, it is not possible to obtain a pumping force sufficient to pass through the above-mentioned sheath 36.3G. 12- A gap is created between the plate-shaped workpiece 5 that has passed through .36.

The gap is detected by a predetermined sensor 37 facing below the shoe 36, and the screw 19.
By stopping the rotation of 19', the amount of plate-shaped workpieces 5 stored in the bending and descending portion 11 is kept constant.

<Another embodiment> It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned embodiments. For example, the four-contact bar may be coated with Teflon, or the bar may be replaced with a Teflon coating. Various aspects can be adopted, such as a pipe body can also be used.

<Effects of the Invention> As in the above 1ffl, according to the invention of this application, in the quantity dividing device for plate-shaped workpieces, the separators connected to the workpiece transfer device linked to the molding machine are arranged in opposite directions for pinching and transferring the plate-shaped workpieces. Since it has a pair of screws and is linked from 1 to rough, basically the plate-shaped workpiece is automatically divided and transferred by the screw, which has an excellent effect of making it easy to detect the V1 mother. Qin will be conquered.

Further, the rod of the actuator installed above the roughs 1 to 1 is movable forward and backward with respect to the pair of screws, and the tip thereof is capable of intervening and retracting from the tip between the screws. Since the actuator and the shutter are linked to the counter facing the tip between the screws, the quantity of plate-shaped workpieces transferred from the screw is automatically reduced. be measured,
Since the shifter and the actuator operate and divide each fixed number of sheets, not only can the number of sheets be divided automatically and accurately, but the number of man-hours required is significantly reduced compared to conventional manual work. This has the excellent effect of reducing costs.

Furthermore, a four-contact bar that guides the workpiece, which is interposed between the workpiece transfer device and the separator, has a bent descending portion directed downward from the dish-shaped workpiece transfer device, and is opened at a lower end and linked to the separator. Since the supply pressure for pressing the plate-shaped workpiece against the separator is secured by the amount of workpieces accumulated at the bent and descending part, the supply pressure to the separator is can be maintained at a constant value at all times, and the biting of the plate-shaped workpiece into the separator is made extremely smooth, which prevents the plate-shaped workpiece from biting poorly due to insufficient supply pressure, that is, uneven biting posture and biting. There is an effect that uneven spacing and damage to the dish-shaped workpiece or reduction in stitch efficiency caused by these will not occur.

Moreover, since the trough and the damper at the front of the screw are tilted forward and upward, the plate-shaped work pieces that are sequentially discharged forward from the screw do not fall forward in the trough, and are prevented from being overturned by the subsequent discharge work pieces. There is no inconvenience in the operation in which the plate-shaped workpieces are accumulated as they are pushed forward one after another.
Furthermore, when the desired number of workpieces is reached, when the plate-shaped workpieces are transferred from the screw to the damper via the trough by the shutter, the plate-shaped workpieces do not fall forward and the work is carried out extremely smoothly. Ru.

Since the container-shaped work transfer amount detection device that enables control of the separator faces the curved descending section (m), the detection device is not used when the workpiece is intermittently transferred. Since the operation of the pallet is automatically controlled, there is no shortage of supply pressure to press the plate-shaped workpiece against the separator, and an excellent effect is achieved in that the workpiece is fed forward in a constant posture and at a constant pressure.
