An embroidery machine includes a plurality of thread reel stand bars, a plurality of thread reels installed to the thread reel stand bars, respectively, a plurality of needles to which threads are supplied from the respective thread reels, at least two of the needles being selected to operate, on the basis of an embroidery data, in order for forming a stitch pattern of multiple colors, a wireless tag attached to each of the thread reels an having information related to the thread wound therearound, and a receiving device, for reading the information in the wireless tag, provided at each of the thread reel stand.

Embroidery machine and embroidery system

An embroidering machine includes a base, an embroidery needle moved reciprocally along a path, an embroidery frame on which a work piece to be embroidered is held, a movable frame provided indirectly or directly on the base and mounting thereon the embroidery frame, the movable frame being driven to transverses the path of the reciprocal movement of the embroidery needle, a wireless affixed to the embroidery frame, the wireless tag storing therein frame information relating to the embroidery frame which is to be selected depending on the work piece to be embroidered, and a receiving device for reading the frame information stored in the wireless tag, the receiving device being provided on the base in immovable manner.

Embroidering machine

An embroidering device includes plural needles for embroidering plural patterns and an operating portion having a display. The patterns are embroidered by selectively actuating the needles in accordance with a command from the operating portion, the display of the operating portion indicates codes of the needles to be used for embroidering the patterns in sequence, and the code of the needle being in actuation is emphatically indicated on the display. Indication corresponding to temporary stop of the actuation can be indicated between the codes if the actuation needs to be temporarily stopped.

Embroidering device

An embroidering system includes at least one embroidering machine having plural needles supplied with threads having different colors, and a control device for transmitting an embroidery data to the at least one embroidering machine so as to selectively drive the plural needles. The embroidery data is generated and memorized in the control device prior to being transmitted to the at least one embroidering machine. The embroidery data is corrected as required. It is preferable that the embroidery data is corrected as the basis for needle numbers for the respective needles and the colors of the threads supplied to the respective needles.

Embroidering system

An embroidering system includes a central control device and a plurality of embroidering machines. The plural embroidering machines are synchronously operated by a command from the central control device. The central control device individually adjusts embroidering speeds of the plural embroidering machines.

A sewing machine includes a plurality of bobbins, thread guiding device, thread selecting device, a needle having an eye, a thread take-up lever having a thread receiving hole, thread taking-out device, movable thread hooking device, and thread letting-through device. The thread guiding device delivers a plurality of threads from the bobbins. The thread selecting device selects one of the threads. The thread taking-out device brings the selected thread adjacent to the eye of the thread. Simultaneously with the thread taking-out action of the thread taking-out device, the movable thread hooking device and the thread letting-through device co-operatively let the selected thread, being disposed between the thread take-up lever and the needle, pass through the thread receiving hole of the thread take-up lever via an opening of the thread receiving hole, and let the leading end of the selected thread pass through the eye of the needle.

Sewing machine

An embroidering machine includes a frame for holding a work piece, a sewing machine for making an embroidery on the work piece, a controller establishing an embroidering operation by moving the frame, under the sewing machine, horizontally and vertically in a common plane based on embroidering data, and establishing calculations, before initiation of the sewing machine operation, of a single time duration required for one single complete movement of the frame based on the embroidering data and a total time duration required for the embroidering operation as a sum of the single time durations, and an indicator for indicating the total time duration.

An embroidering machine comprises a body including a bed and an arm which is formed on the bed, a frame for holding a work, a movement device for moving the frame along the bed in the horizontal direction, an embroidering device set in the body for embroidering the work, a detecting device for detecting a pattern which is drawn on the work, and a controller for controlling the movement means based on an information which is detected by the detecting device.

An apparatus for detecting a stepped portion between an upper cloth and a lower cloth on which the upper cloth is mounted, including a light-emitter for transmitting light to a light receiver. The stepped portion is detected based on a decrease in light received by the light receiver. In order to assure detection of the stepped portion, an optimum amount of light to be emitted from the light-emitter is determined so that a deviation between a transmissivity of the lower cloth and a transmissivity of both cloths arranged in a layered configuration may be maximized.

Apparatus for detecting the end of cloth-overlap on a sewing machine

A detecting device of the feeding quantity of material in a sewing machine includes a dial rotatably mounted on an arm of the sewing machine, a mechanism operatively connected to the dial for varying the feeding quantity in response to the rotational quantity of the dial, a signal generator converting the rotational quantity into the electric signals, and a display device electrically connected to the signal generator for displaying signals outputted therefrom.

Detecting device of the feeding quantity in a sewing machine

An apparatus for detecting the terminus of cloth being sewn by a sewing machine. A plurality of sensors are disposed on a path along which the cloth is fed and at positions upstream of the needle, and they each consist of a light emitting portion and a light receiving portion paired and disposed in opposition. A detector electrically detects a set cloth feed amount, and a selection circuit operates to electrically select one of the sensors which is positioned at the optimum position with respect to the set cloth feed amount.
