摘要： To provide an automatic cloth spreading machine that can keep up the number of pieces processed even in the event of failure in handling. This automatic cloth spreading machine includes a separating means for separating pieces of cloth one by one from a mass of cloth consisting of a plurality of pieces of cloth by cloth handling devices, an edge locating means for locating an edge of each of the pieces of cloth having been separated one by one, a spreading means for spreading the piece of cloth, the edge of which has been located, and a discharging means for discharging the piece of cloth having been spread to a subsequent step. The separating means includes multiple units of cloth handling devices that perform the same process, and the multiple units of cloth handling devices simultaneously perform at least one of single- or multiple-step processes of separating pieces of cloth one by one from the mass of cloth.

摘要： It is an object to provide a cloth spreading apparatus capable of eliminating the troublesome work of pulling a cloth when the cloth is held by feeding chucks to reduce burden of the worker and operation time. A cloth spreading apparatus 10 comprises a pair of feeding chucks 22a and 22b grasping adjacent corners Ca and Cb of a cloth C, a moving device 26 for moving the pair of feeding chucks 22a and 22b between a feeding position and a delivery position of the cloth C to draw the cloth, and spreading chucks 42a and 42b for receiving the cloth C directly or indirectly from the pair of feeding chucks 22a and 22b and spreading the cloth C in a direction of separating the adjacent corners Ca and Cb from each other. The moving device 26 has separate moving trajectories p1 and p2 corresponding to the respective feeding chucks 22a and 22b so that the pair of feeding chucks 22a and 22b can move between the feeding position and the delivery position independently of each other.

摘要： Provided is a cloth spreading apparatus in which a pair of feeder chucks are engaged with adjacent corners of a piece of cloth at a lowered position, and raise the cloth to a traversing position of spreading chucks; the pair of spreading chucks traverse to positions closer to each other to receive the adjacent corners of the cloth from the feeder chucks, and then traverse to positions farther away from each other to pull the adjacent corners so as to spread the cloth; an intermediate movable body receives, at an advanced position, an upper end portion of the spread cloth from the spreading chucks and retains the upper end portion, and then releases the upper end portion while moving to a retracted position so as to transfer the cloth onto a belt conveyor; and the belt conveyor carries out the cloth in a spread state, wherein the intermediate movable body has: a rear-facing surface that is a part of an upper surface between a front part and a sunken part located at a lower level than the front part, and that extends downward; a clamp that is placed opposite to the rear-facing surface; and a clamp driving device that advances and retracts the clamp to and from the rear-facing surface so as to hold an upper portion of the cloth between the clamp and the rear-facing surface and release the upper portion from therebetween.

摘要： To provide a cloth piece folding device capable of folding a cloth piece accurately through adjustment of a driving speed of a bending plate. A cloth piece folding device includes a conveyor (12) to transfer a cloth piece (Y), a bending unit (32) to fold the cloth piece (Y), and a controller (50) to control operation of the bending unit (32). The bending unit (32) includes a bending plate (32a) and an actuator (32d) to make the bending plate (32a) move forward and backward. The actuator (32d) is capable of controlling an operating speed. The controller (50) adjusts a driving speed of the bending plate (32a) by controlling an operating speed of the actuator (32d) depending on a transfer speed of the conveyor (12). The driving speed of the bending plate (32a) is adjusted by the controller (50). This synchronizes the transfer speed of the conveyor (12) and the driving speed of the bending plate (32a) with each other. As a result, the cloth piece (Y) can be folded at a suitable bending position, so that the cloth piece (Y) can be folded accurately.

摘要： Provided is an apparatus and a method for inspecting a cloth piece, by which dirt and a tear can be reliably distinguished, and which have high accuracy to detect the dirt.
The apparatus for inspecting a cloth piece includes: an inspection table 20 having a dark color section 21 and a light transmitting section 22; a first inspection camera 41 for picking up an image of reflected light from a cloth piece T passing through the dark color section 21; and a second inspection camera 42 for picking up an image of transmitted light through the cloth piece T passing through the transparent section 22. The dirt and the tear can be reliably distinguished by determining an area where the reflected light and transmitted light are both darker than a surrounding area to be dirt and by determining an area where the reflected light is darker than the surrounding area and the transmitted light is brighter than the surrounding area to be the tear. The dirt inside the cloth piece is emphasized, thereby providing high detection accuracy to detect the dirt.

摘要： The present invention aims to achieve a lower cost of a negative pressure source and thereby of a cloth spreading apparatus and/or a reduction in power consumption of a negative pressure source during operation of a cloth spreading apparatus. This cloth spreading apparatus includes: a spreading unit having spreading clamps that spread an upper-side part of a fed cloth in a right-left direction; and an ejection unit having an intermediate movable body that, while moving backward from a forward position, releases the upper-side part of the cloth that the intermediate movable body has received from the spreading clamps in the forward position and held onto an upper surface by sucking, and a belt conveyor that receives the upper-side part of the cloth having been released by the intermediate movable body and ejects the entire cloth backward. The ejection unit has: a large number of suction holes that are dispersedly disposed in the upper surface of the intermediate movable body, at least over a lateral range corresponding to a set maximum lateral width of the upper-side part of the cloth; a negative pressure source that sucks out air inside the intermediate movable body to form a negative pressure region inside the intermediate movable body; and sucking force maintaining means that maintains a sucking force of the suction holes regardless of whether the lateral width of the upper-side part of the cloth is large or small.
