Uncut sheet material and release paper are cut. That is, delicate adjustment of the cutting depth is frequently required.

(C) The output of the press device is large, and a force of several tons is required. In other words, the size of the device increases,
More space. (2) Manual release and attachment of the sheet release paper is usually performed, and it is difficult to automate a series of steps of cutting → peeling → pasting, thereby causing the following problems.

(A) Poor productivity. In other words, stable quality and continuous operation production are difficult.

[0009] (b) There is a limit in terms of sticking accuracy.

When there is no jig pallet, the positioning device 803 is released by the instruction of the control means 1000, and the jig pallet 802 is moved by the transport belt 801. The sheet is discharged and transported in the direction of arrow S.

The above has described one cycle of the present embodiment.

Next, the operation of this operation will be described with reference to FIG.

In FIG. 16, blocks in row 910 represent the positioning operation of the jig pallet on the conveyor. 91
One row shows the operations of feeding the seal, cutting / peeling, and transferring the temporary placing table seal. Column 912 represents the operation of sticking and sticking the sticker of the sticking finger. Row 913 indicates the operation of releasing and discharging the positioning of the jig pallet on the conveyor. Conveyor condition A is that the sensor of the conveyor device satisfies both sensor 805b = ON (with jig pallet) and sensor 805c = OFF (without jig pallet). Next, the conveyor condition B is that one of the sensors of the conveyor device, that is, the sensor 805b = OFF (no jig pallet) and the sensor 805c = ON (the jig pallet is present) is satisfied.

FIG. 16 shows the state from the initial state over time. First, after completion of 911 rows, conveyor condition A9
01 (that is, the seal to be cut and peeled next is a conveyor condition that can be reliably applied within a certain period of time).
The operation starts in the 11th row. That is, the 912 column operation and the parallel operation are performed. The same operation is performed under the next conveyor condition A902. According to the next conveyor condition B (that is, the seal to be cut and peeled next is a conveyor condition for which there is no guarantee that the sticker can be stuck within a certain period of time), the operation in row 912 is performed as it is, but the operation in row 911 and row 913 is the conveyor condition. This is performed after A904 is completed. Next 91
Since the operation in one row is the conveyor condition A905 at that time, the operation in the 911 row is immediately performed.

As described above, according to the present invention,
The following effects can be obtained. (1) It is possible to automate the sheet member cutting / peeling process which has been conventionally performed manually. (2) It is possible to automate a series of seal supply-pasting devices including a pasting step after peeling of a cut seal.

By changing the start of cutting using ultrasonic vibration of the seal according to the conditions of the conveyor, reliability and productivity can be improved as described below. (1) Since the seal is not held in the cutting blade for a long time, a seal having a stable shape can be supplied to the temporary placing table. (2) Since the seal is not held on the temporary mounting table for a long time, it is possible to prevent a suction error due to the sticking finger due to an increase in the adhesive strength of the double-sided tape. (3) Since the cutting and peeling of the seal and the sticking operation are performed while discriminating when the sticking operation can and cannot be performed in parallel, the maximum productivity while ensuring the stability of the sticking quality can be realized.
