Abstract

PURPOSE:To make sure of separation of the lowermost one of piled sheets in a pile guide device by means of a pair of rubber suckers accompanied with the up and down motion of an actuating lever, and to forward the separated sheet properly to working areas by the reciprocal motion of the pile guide device. CONSTITUTION:The lowermost one of leather convers which are piled up in a pile guide device 110 is sucked by a pair of rubber suckers 132a and 132b by the first half upward motion of an actuating lever 130, then is separated by the subsequent second half motion, and next is forwarded to No.1 working area in the section which is in front of a check click 132a by the first half motion of the pile guide device 110. In this section a heater for a center rounding process is arranged. After the pile guide device 110 has been restored to the initial configuration, the center rounding process is performed simultaneously when sucking and separating actions are performed by the subsequent first half motion of the actuating lever 130. Then the cover is forwarded to No.2 working area by the second half motion of the pile guide device 110, and bonding work with a center still is performed in this section with adhesive coated to the outside of the cover surface.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to separation and conveyance of laminated flexible sheets that can be incorporated into a flexible sheet processing and assembly apparatus such as a fully automatic cover pasting apparatus. Regarding the mechanism.

[Conventional technology]

Conveyance mechanisms that assemble electronic devices and electrical products on an automatic conveyor workbench using a belt conveyor, and sequentially machine metal workpieces on an automatic conveyor workbench have been widely used in recent years. However, it requires program control by a sequencer and a large number of actuating means using pneumatic and hydraulic pressure, resulting in a complex configuration. For this type of transport mechanism,
Although it is possible to separate and convey laminated flexible sheets by combining robot hands with suction cups and having them take in and return work in each work area, the structure becomes complicated.

[Problems with conventional technology]

A fully automatic separation/transfer mechanism with a simple structure, less occurrence of breakdowns, and stable operation is more suitable than a complicated mechanism that requires a lot of effort.

[Means for solving problems]

The separating/conveying mechanism for stacked flexible sheets of the present invention includes a stacking guide means for holding and feeding a large number of flexible sheets fed in one direction in a stacked state by a holding guide;
a reciprocating drive means that is connected to the lamination guide means and performs intermittent reciprocating motion by a drive source and a swinging means; and a reciprocating drive means that is spaced apart from the feed side of the lamination guide means and causes the lamination guide means to reciprocate. Sheet separation means is disposed at a position opposite to the bottom sheet, and is intermittently driven reciprocally in a direction perpendicular to the direction of the stack, so that the working portion comes into contact with the stacked lowest sheet in the forward motion and separates the stacked sheets in the backward motion. The work rod is provided with check claws which are biased to an upright state at appropriate intervals in the longitudinal direction of the reciprocating direction of the lamination guide means so that they fall down by a force in the forward direction and stand up by a force in the backward direction. a support body interposed between the stacking guide means and the work frame to assist the stacking guide means in holding the sheet during reciprocating movement of the stacking guide means; a feeding force effecting frame which is connected parallel to the working rod and is biased to an upright state at the same interval as the non-returning pawl, falling down by a force in the forward direction and standing up by a force in the backward direction; The present invention is characterized by comprising a drive control means for controlling the intermittent reciprocating motion and stroke of the working frame and the working rod, and a machine base incorporating each of the means.

[Effect]

The stacking guide means keeps the flexible sheets inserted in one direction in a stacked state even during reciprocating movement, and the separating means sends out the # sheets one by one. Moreover, sheets can be replenished in a timely manner and the apparatus can be operated in a connected manner. The reciprocating drive means reciprocates the stacking guide means intermittently at appropriate cycles, and one sheet separated by the reciprocating movement is sequentially transported to a work area by an integrally connected feeding frame. The working rod brings the lowermost stacked sheet into contact with the separating means and adsorbs it by the forward movement of the reciprocating means, and separates one sheet by the backward movement, and at the same time, the working rod is moved to the feeding frame spaced apart in the longitudinal direction. The sheets transferred are held in one piece by the non-return claw. The claws provided on both rods allow mutual feeding only in the forward direction. The support supports the opposite side of the protrusion of the sheets stacked within the stacking guide means during reciprocating motion, and also presses, heats, and suppresses and deforms the sheets that come up as the working rod moves forward.

Assist with work such as drilling and painting. The drive control means is -
A cam mechanism or a sequencer or the like controls the intermittent reciprocating motions of the reciprocating drive means of the work rod and the force-feeding frame at predetermined strokes so as not to interfere with each other. The machine base holds each of the above-mentioned means arranged between Tokuma and Naka.
