Abstract

PURPOSE:To transfer a sheet material group correctly regardless of a difference in height between a grip finger position and a sheet material group support surface by inclining the grip fingers to bring the forward end of the fingers close to the support surface at a sheet material handling position and opening the grip fingers. CONSTITUTION:A sheet material transfer apparatus C is on standby with grip fingers 10 opened at a standby position fixed by a sensor S2. The transfer apparatus C is advanced toward a receiving table 2 placing a sheet material group B of a fixed number of sheets thereon, and stopped at an operating position of a sensor S1. Subsequently, an air cylinder is operated to close the grip fingers 10, thereby clamping the sheet material group B, and then the transfer apparatus C is moved to the right at a high speed until it reaches the position of a sensor S3. After that, the apparatus is moved to the left at a low speed as far as the position of a sensor S4. During low-speed movement, a finger support member 14 is inclined with the grip fingers 10 by an air cylinder 23, and when it reaches the sensor S4 position, the grip fingers 10 are opened to place the sheet material group B on a support surface 3.

U Ss 't'J,' position [i1 detection sensor, in the one shown, sb 20 is partially broken] - Ise IL consists of a 7mm rotary switch and is installed in the machine frame 17. However, even optical sensors such as proximity switches, other photoelectric elements, and air pressure sensors cannot be used. valley sensor s
l, s2+S3. The mounting positions of S4 and Ss can be adjusted by moving along the length of the rail 18 according to the length of the sheet group Bυ.

The position detection sensors 2'L and 2'L are the gripping position detection sensor S1 on the most upstream side and the standby position detection sensor S on the downstream side.
2. In the deceleration position 1, the detection sensor s3, the gripping claw position detection sensor S4, and the most downstream end position detection sensor s5 are sequentially depressed.

[Function] First, as shown in FIG. 6, the sheet-like material conveying device 0 is placed on standby at a standby position determined by the standby position detection sensor S2, with the gripping claws IO in an open state.

Then, the bag making machine AICj: stacks sheet-like materials one after another on the pedestal 2, counts them with a cycle counter, receives this set value arrival signal VCj, rotates the motor 24rf, and uses the moving frame 20 to The gripping position of the gripping position detection sensor S1 is detected by the gripping position detection sensor S1. At the same time as the motor 24 is stopped, the first assuring device 22 is activated, and the sheet group B is clamped by closing the 7m non-jaw 10?L-.

Next, upon completion of this clamping (receiving the number Mr), the motor 24 is rotated in reverse, the moving frame 20 is moved in the downstream direction e, and the sheet-like object group B is carried out by the cradle 2. When the frame reaches the position of sensor S3, this output signal KJ: The motor 24 marked with # is switched to low speed while rotating in reverse.
As the L1 moving frame 17 approaches the position of the inter-gripping claw position sensor S4, the claw supporting member 14 is tilted by the VC together with the grasping claw 10 by the air cylinder device 23.
1a is a position VC in close contact with the support surface 3VC at the sheet-like object processing position.9When the moving frame 20 reaches the sensor S4, this output signal VCX is used to operate the first air cylinder device 22 to release the gripping claw. 1O (11-open, # moving frame 2o moves in the direction of the guide rail 18 with b≦o, sheet-like object group Bl-]: Completely 1c from Ja-ja nail 1o

- When the tray is placed horizontally on the support surface 3 at the tray processing position, the motor 24 is returned to normal rotation at the most downstream position detection sensor TS5, and the pawl support member 14 and The gripping claw 1o returns to the horizontal state 9, and when it moves to the standby position detection sensor S2 position, the movement is stopped by the output of the sensor S2 (number N).

The above operation is repeated each time a predetermined number of sheets constituting one sheet-like object group B2 are stacked on the pedestal 2.

[Effects of this invention]

As mentioned above! -9, this output is constructed and operated, and the stacked sheets are stacked with a beam-like object like Group A B, and the pedestal is placed next to the sheet-like object processing position. Even if there is a step between the gripping claw 1o and the support surface 3, the gripping claw 1o
is inclined, and the tip of the sled is brought close to the support surface 3, and the grasping claws 10 of the sword S are opened. Is this an effect?

[Effects of Mr. M]

As mentioned above, the moving frame 20 +-1 Niji r + "" Miku 1
0'(r) Since the transfer speed decreases immediately before separation, and the sheet material DB separates after reaching a low speed, II'i moves to the correct position of the sheet material DB processing position.

In addition, at Mr. Shoji, each sensor S1゜S2,
531S4 and S! , can be moved along the guide rail 18 and fixed at 14 nodes, so the length of the sheet-like object group B,
It can be adjusted to the sheet material processing position, so operations can always be performed in accordance with the purpose.

The operating power of the sequence control mentioned above includes a motor, an air cylinder device VC limit of 7'L, a hydraulic mechanism,
Even in the case of a rope machine, a solenoid, etc., the signal supporting the sequential movement is simple and inexpensive to use a group of sensors as described above, but it may also be numerically controlled by a computer or the like.
