Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet transfer device, particularly in a process for forming perforations on a calendar or the like.
The present invention relates to a transfer method or a transfer device that puts a work into a processing unit and takes out a product from the processing unit.

2. Description of the Related Art Generally, a monthly calendar has a structure in which a plurality of sheet groups including a cover sheet are bound on one side of six or twelve calendar sheets. Is perforated. In recent years, as shown in FIG. 7, one side of a calendar sheet is bound by heat welding, and a bent portion for reinforcement is formed in this portion, which has been proposed. Perforations are essential.

When this perforation is processed, the part to be processed of the calender is stopped at the processing position of the punching device for a certain period of time, and after completion of the processing, it is taken out from the processing position along its plane. Then, in order to ensure the smooth progress of these series of operations, the insertion locus and the ejection locus of the calendar are often set on the same plane at right angles or in straight directions.

In this case, the total required time from the start of loading to the completion of removal is normally the sum of the required time to reach a predetermined processing position, the required processing time, and the required time to be removed. Therefore, if the time required for each process is shortened, the total time required can be shortened. However, there is a limit to reducing the time required for each process,
Since the speed of each process is too high, a problem such as a decrease in processing accuracy occurs.

The present invention has been made in view of the above-mentioned point. "The flexible sheet-like work (W) is put into a processing position and stopped, and in this stopped state, the work (W) is subjected to predetermined processing. Then, in the method of transferring sheets, which is then taken out along the processing position plane, the problem is to be able to shorten the total time required from the input of the sheet-shaped workpiece to the completion of the taking out. To do. [Invention of Claim 1]

[0006]

[Technical Means] A technical means of the present invention for solving the above-mentioned problem is to "follow a work (W) in a state where at least a part of the preceding sheet-like work (W) is in a processing position.

[0007]

[Operation / Effect] While the preceding work (W) is being processed at the processing position, or while it is being taken out, the feeding operation of the subsequent work (W) to the processing position is started. Moreover, the preceding work (W) and the following work
Each operation is executed with (W) partially overlapping. That is, the subsequent work (W) can be put into the processing position without waiting for the preceding work (W) to complete the escape from the processing position.

Therefore, a part of each process proceeds at the same time, and further, the transfer distance from the starting point of loading the work (W) to the processing position can be shortened, and the total required time from the loading of the work (W) to the completion of the removal. Since the time can be shortened, the work work on the work (W) can be speeded up. [Invention of Claim 2]

[0009]

The large-diameter roller (61a) is used as the transfer roller near the rear end of the work (W) at the processing position and on the upstream side in the transfer direction by the transfer device (6).

[0010]

[Operation / Effect] When the above-mentioned technical means is adopted, when the preceding work (W) is completely processed, the take-out device
The transfer of this work (W) to the take-out position is started by (7), and at the same time, the transfer operation of the subsequent work (W) is executed by the transfer device (6). Then, when a part of the preceding work (W) remains at the processing position and the rear end and the tip of the following work (W) match, this tip is lifted by the large diameter roller (61a). Since it is in the state, it is sent to the upper surface of the preceding work (W).
Then, the following work (W) is the large diameter roller (61a) and the transfer roller on the upper side of the transfer device (6) in the transfer direction.
(61) (61) is transferred to the processing position, and at the same time, the preceding work (W) is taken out of the processing position by the take-out device (7). Then, when the preceding work (W) is completely escaped from the processing position, the work (W) is supported by the transfer rollers (61) (61).

In this way, the invention of claim 1 can be smoothly carried out. Moreover, according to this device, in order to realize the operation of climbing the leading end of the succeeding work (W) onto the preceding work (W), a part of the transfer rollers (61) (61) of the transfer device (6) is Since only the large-diameter roller (61a) is used, the configuration is extremely simple.

(A) is provided with a sheet feeding device for feeding the laminated sheet (10) placed on the support table to the sheet holding section (30) side of the main transfer device (1).

As shown in FIG. 1, this sheet feeding device is provided with support rods (1) provided on both sides of a support base and extending on both sides of a sheet holding section (30) which is stopped facing the input station (A). 19)
(19) and a reciprocating carriage (18) that reciprocates between these support rods at a predetermined timing. Then, by the operation of the reciprocating carriage (18) moving from the initial position to the most advanced position, the holding device (3) of the sheet holding part (30) facing the laminated sheet (10) placed on the support base. Is supplied to.

The paper feeding operation is interlocked with the operation of the cylindrical cam (5). As mentioned, the loading station (A)
When the sheet holding part (30) faces the sheet holding part (30), the roller (37) of this is in contact with the lowermost part of the cam surface of the cylindrical cam (5), and the sheet holding part (30) is at the most lowered position. It is in.
In this state, the support plate (3a) and the pressure plate (3b) are opened by the operation of the air cylinder (32). In this open state, the support plate (3a) is in the horizontal posture and the pressing plate (3b) is swinging upward.In the initial stage of feeding, the four holding devices (3) (3) Support plate for our top retaining device (3)
(3a) coincides with the upper surface of the support rods (19), (19).

Therefore, the laminated sheet (10) placed on the base end side of the support rods (19) (19) of the support base is supported by the reciprocating carriage (18) which operates at a predetermined timing. ) Is sent to the tip side. At this time, since the upper surfaces of the support rods (19) (19) and that of the support plate (3a) are aligned with each other, the support plate (3a) is surely
Will be posted on. After this, the reciprocating carriage (18)
Is returned to the initial position, and the cylindrical cam (5) rotates a certain angle to face the sheet holding section (A).
(30) is lifted by a constant stroke as a whole, and the support plate (3a) of the holding device (3) at the next stage is aligned with the support rods (19) and (19). Then, in this state, the next laminated sheet (10) is similarly supplied.

The support plate (3a) and the pressure plate (3b) are shown in FIG.
As described above, a rectangular auxiliary plate (38) made of an elastic material is provided, and the lateral width of this auxiliary plate (38) is slightly smaller than the interval between the support rods (19) and (19). Therefore, auxiliary plates (38) (38)
The support plate (3a) and the clamping plate (3b) that are equipped with the support rod (19)
The laminated sheet (10) that enters between the (19) and is extruded by the reciprocating carriage (18) can be reliably held by the holding device (3). [Regarding the binding station (B)] This binding station (B) is used to press the sandwiched portion (1) of four laminated sheets (10) (10).
1) (11) is heated and pressed at the same time to form a binding side portion (12) having a bent cross-section portion (13) on the sandwiched portion (11) of each laminated sheet (10) as shown in FIG. 7. It is what constitutes. Therefore, as shown in FIG. 2 and FIG. 8, in the pressure bonding device installed in the stitching station (B), there is a space between the fixing plate (21) at the upper end and the driving side pressure plate (22b) at the lower end. 3 movable pressure plates in (22) (22)
Is intervening. These pressure plates are individually heated by a heater (27), and the upper surface of the lower pressure plate is provided with a ridge (24) following the bending cross-section (13) of the binding side (12). , The lower surface of the upper pressure plate is a concave groove adapted to the ridge
(25) is formed. Then, when the pinched portion (11) is pinched by the upper and lower pressure plates, a bent cross-section portion (13) corresponding to the ridge (24) and the groove (25) is formed. .

In this embodiment, as shown in FIG. 2, in the non-pressurized state, a predetermined gap is formed between the pressure plates, but the drive side pressure plate (22b) to the cylindrical cam (5). The receiving plate (26) projects horizontally toward the vicinity of the cam surface of (). Then, the tip of the receiving plate (26) is in contact with the auxiliary roller (37a) continuously provided with the roller (37). Therefore, when the drive device for raising and driving the drive side pressure plate (22b) in the pressure device operates, the tip of the receiving plate (26) lifts the auxiliary roller (37a). That is, the sheet holding unit (3) including the holding devices (3) and (3)
0) is lifted together. As a result, the above-mentioned five hot plates are interposed between the four pressed parts (11) (11).
Pinch. The laminated sheet (10) (1
Since the supporting position of (0) rises, the binding side part (1
The formation process of 2) proceeds smoothly. Then, when the sandwiched state is maintained for a certain period of time, the sandwiched portions (11) (11) of the sheets constituting each laminated sheet (10) are heated and welded to each other, and the binding side portion (12) is bent. A cross section (13) is formed.

After this, the drive side pressure plate (22b) returns to the bottom dead center, the pressure applying device returns to the initial state, and each pressure unit (2)
Opens. In this returning state, the roller (37) is in contact with the horizontal surface portion (5a) of the cylindrical cam (5) and each holding device (3) of the sheet holding portion (30) is attached to the pinched portion (11). The completed laminated sheet (10) is held under pressure. [Punching station (C)] At the punching station (C), the perforation (14) of the laminated sheet (10) shown in FIG.
And a locking hole (15) is formed.

Each holding device of the sheet holding unit (30)
A transfer device (6) for taking out the laminated sheet (10) held by (3) separately and sending it to the punching device (P) is provided. Further, a take-out device (7) for taking out the laminated sheet (10) after completion of processing from the punching device (P) is adjacent to the punching station (C). The punching device
(P) is an ordinary punching device, which performs a punching operation each time the laminated sheet (10) is put into a predetermined position to form each part by a die corresponding to the perforations (14) and the locking holes (15). It is a form of punching out.

As shown in FIGS. 9 and 10, the transfer device (6) comprises a plurality of transfer rollers (61) (61) arranged side by side in the transfer direction, and each roller is a motor (63). It is constantly rotating by the transmission with the belt (62) driven by. The starting point of this transfer roller group is within the descending movement locus of the portion of the binding side portion (12) protruding from each holding device (3) of the sheet holding portion (30) located facing the punching station (C). It is protruding.

Therefore, as described above, when the sheet holding portion (30) at the highest position is lowered intermittently as a whole, as shown in FIG. 9, the sheet is initially held by the holding device (3) at the lowermost stage. The binding side portion (12) of the laminated sheet (10) thus brought into contact with the transfer roller (61) at the starting point of the transfer roller (61) (61) group. Holding device at this time
(3) is in an open state, and the transfer device (6) sends the laminated sheet (10) to the processing section of the punching device (P).

In this embodiment, a swing roller (65) which swings at a predetermined timing with respect to the transfer roller (61) at the starting point is provided, and the binding side portion (12) is the above-mentioned. When the transfer roller (61) at the starting point is contacted, the swing roller (65) retracted upward until then moves downward, so that the binding side is between the transfer roller (61) below. It is configured to be sandwiched between. Further, the clamping pressure is set to a weak one and it is configured to be able to freely return to the elevated position. Therefore, the laminated sheet (10) is surely started to be transferred to the punching device (P) side. At this time, since the rocking roller (65) can be raised and returned freely, when the bent cross section (13) passes, it rocks in accordance with this cross section. After the bent cross section passes, when the laminated sheet (10) is positioned at the processing portion of the punching device (P), the swing roller (65) is moved upward by a driving device such as an air cylinder provided separately. It is rocked and retracted.
As described above, in the case where the swing roller (65) is adopted, the transfer operation of the laminated sheet (10) can be started smoothly and surely.

Since the punching device (P) has a positioning stopper (S), the laminated sheet (10) is simply placed on the transfer rollers (61) (61) group. From
At this point, the laminated sheet (10) is positioned and stopped.
During this period, the punching operation of the punching device (P) is executed, and the perforation (14) and the locking hole (15) are punched. In addition, as shown in FIGS. 10 and 11, the take-out device (7) is a transfer device.
It is composed of a pair of rodless cylinders (71) that reciprocate in the direction perpendicular to the transfer direction of (6), and clamp devices (72) (72) attached to the output part (71a) of the rodless cylinders (71). And
The operation of the rodless cylinder (71) of the clamp devices (72) (72) is controlled so as to reciprocate between the receiving position (T ₁ ) and the extracting position (T ₂ ). Then, at the receiving position (T ₁ ), the clamp device (72) (72) closes from the open state to the clamp state, and at the take-out position (T ₂ ) the clamp device (72)
This clamp operation is controlled so that (72) operates to open from the clamp state to the open state.

Therefore, during the punching operation by the punching device (P), the clamp devices (72) (72) advance to the receiving position (T ₁ ) to clamp one side of the laminated sheet (10). When the punching is completed, the rodless cylinder (71) drives the clamp devices (72) and (72) to the take-out position, and the product is taken out. Then, when the take-out position (T ₂ ) is moved, the clamp claws (73) (73) of the clamp device (72) (72) are opened and the product is released from the clamp device (72) (72), and at the same time, the rodless cylinder. The clamp device (72) (72) re-enters the receiving position (T ₁ ) by the operation of (71), the clamp claws (73) (73) close at a predetermined timing, and one side of the laminated sheet (10) clamps. To be done.

In this embodiment, the time required for feeding the laminated sheet (10) by the transfer device (6), punching operation by the punching device (P), and taking out the product by the take-out device (7) is shortened. Therefore, the operation of the transfer device (6) and the operation of the take-out device (7) proceed simultaneously. Therefore, among the transfer rollers (61) (61), the roller near the rear end of the laminated sheet (10) in the positioned state and on the upstream side in the transfer direction by the transfer device (6) is the large-diameter roller (61a). I am trying.

By adopting this structure, the laminated sheet (10) taken out from the sheet holding portion (30) can be used as a punching device.
Even when the preceding laminated sheet (10) is being taken out from the processing section by the take-out device (7) when being transferred to the processing section in (P), as shown in FIG.
The leading end of the subsequent laminated sheet (10) which has reached a) rides on the preceding laminated sheet (10) and is transferred to the processing section.

Therefore, it is possible to shorten the time required from the insertion of the laminated sheet (10) to the removal thereof in the punching device (P). In addition, in this transfer device (6),
From the laminated sheet (10) positioned on (P), transfer roller (6
1) The distance to the rear end of the installation area of (61) is set shorter than the length of the laminated sheet (10). And a large diameter roller (61
The distance between a) and the stopper (S) of the punching device (P) is set to the length of the laminated sheet (10). That is, the overlap distance between the preceding laminated sheet (10) and the following laminated sheet set at the punching position is the sum of the punching time and the time required for the laminated sheet (10) to escape from this punching position, Determined in relation to the transfer speed of the transfer device (6).
When the laminated sheet (10) is completely ejected from the punching position and the following laminated sheet (10) is set to the punching position, the overlap distance is the longest, and the time required at this punching station (C) Can be shortened most.

[Overall Operation] Loading Station
In (A), the support rod (19) is moved according to the movement of the reciprocating carriage (18).
The laminated sheet (10) is placed on the base end of (19). at first,
The sheet holding portion (30) located opposite the input station (A) is at the lowest position, and the support plate (3a) of the uppermost holding device (3) and the support rods (19) (19) are Are matched. At this time, the output shaft of the air cylinder (32) of the sheet holding portion (30) is at the return position, the pressing plate (3b) is swung upward, and the holding device (3) is opened. . Therefore, when the reciprocating carriage (18) is transferred to the final position, the laminated sheet (1
0) is put in a predetermined position in the holding device (3). At this time, the closing direction is set so that the pinched portion (11) is located rearward.

After that, the second drive device (51) is driven by a predetermined amount while the first drive device (52) is stopped. Then, with the main shaft (1a) and the seat holding part (30) stopped at their plane positions, the cylindrical cam (5) rotates clockwise by a certain angle, and the seat holding part (30) is acted by the cam mechanism. After being lifted, the second holding device (3) from the top coincides with the support rods (19) and (19) and stops for a certain period of time in this state, during which the next laminated sheet (10) is loaded. In this way, each holding device
The laminated sheets (10) are sequentially placed in (3).

Then, the cylindrical cam (5) rotates clockwise by a total of 120 degrees by the time the loading into the four holding devices (3) (3) is completed, and when this loading process is completed, the air cylinder (32) actuates to lower and swing the pressure plate (3b) to close each holding device (3) and hold the loaded laminated sheet (10) under particular pressure. Then, the first drive device (52) rotates the main shaft (1a) counterclockwise. As a result, the sheet holding unit (30) facing the loading station (A) is
It is rotated integrally with a) and transferred to the binding station (B), and the four pressed portions (11) of the laminated sheets (10) and (10) are applied to the binding station (B). It is inserted into the pressure part (2) from its side.

At the time of this transfer, the pinched portion (11) of the laminated sheet (10) and the portion in the vicinity thereof are projected from each holding device (3), and this protruding portion is stably moved. In addition, in order to make sure that each of the laminated sheets (10) is inserted into each pressurizing portion (2), the arc-shaped guide plates (8) and (8) are attached to each laminated sheet (10) as shown in FIG. It is arranged along the movement path of the pressed portion (11).

Therefore, during the transfer, there is no fear that the pinched portion (11) and its vicinity will hang down. Since the cylindrical cam (5) and the main shaft (1a) rotate relative to each other by the transfer operation, the cylindrical cam (5) and the roller (37) of the sheet holding unit (30)
The relationship with and returns to the initial state, and the loading station (A)
The sheet holding portion (30) facing the is at the lowest position. Therefore, in the loading station (A), the same loading operation of the laminated sheet (10) as described above is executed. In the binding station (B), the driven side pressure plate (22b) is driven upward to clamp the pinched portions (11) inserted in the respective pressurizing sections (2), thereby binding the side sections (12). Is processed into.

The time required for the pressure-bonding step in the stitching station (B) and the time required for loading the four laminated sheets (10) and (10) in the loading station (A) are matched with each other. The movements proceed simultaneously. At the binding station (B), when the sticking is completed, the main shaft (1a) rotates by a fixed angle (120 degrees), so that the sheet holding unit (30) facing the binding station (B) Face the punching station (C).
