Abstract

The embroidery machine, and especially a shuttle embroidery machine, is for the attachment of sequins, pearls, stones and the like, carried on a ribbon. The ribbon is advanced by a peg wheel, with an intermittent drive. The ribbon guide (25) is a swing lever, with a magnet (27) at its free end, to hold the lever in the closed position at a ferromagnetic limit stop (37). When the lever is open, the ribbon can be moved easily into the machine without a shaft (17) rotation. In operation, the ribbon is advanced in steps to bring each sequin opening into position in front of the needle (11) for the needle to penetrate through and the sequin is detached (31) from the ribbon by a beating plate. On a blockage, the swing lever is moved away from the peg wheel.

Description

1322206 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to an embroidery machine (Stickmaschine, especially embr〇idery), especially Schifflistickmaschine, for embroidering a sequin (Paillette) Or a device of the like - the sequins or the like may be supplied in a string, the device having an intermittently driven sprocket (Warzenrad, English: wartwheel) to carry the string and have a guide The lead piece partially encloses the enamel strip and has everything away from the device, and a sequin is cut from the string before the embroidering. Further, the present invention relates to an embroidery machine having a plurality of such embroidering devices. [Prior Art] A device for embroidering decorative materials has been used for about a hundred years. For example, in German Patent DE 174086, a so-called glittering sheet (i.e., a (S)) glossy scale (SchUppe) is sewn onto a cloth, wherein the glittering sheet is used. (Also known as "bright: ^ otherly supplied from the tubular container to the needle. Thus, the needle passes through the hole provided in each of the glittering pieces and fixes it to the cloth. In the device, the material is Supply in the form of a string. Therefore two: special:: 〇93. _ mentioned a kind of beads = each / method and device, which supply - strips of beads, and in the like ... set in the United States: For the town of sequins or such conventional devices, the string of 3, 3 needle pushers (above Nadelstossel)::: string rolls (they are set on the wheel) to the needle. In order to introduce the string into the ^ send ^ for example A chain-guide (which is pivoted, that is, the distance from the - sequin to another sequin) is not allowed, the band cannot be correctly detected and the + y is pulled out and clamped. Another The disadvantage is that the guiding channel is long,

It cannot be explored for inspection. Thus, the risk of the string being broken () increases the length of the passage 'not only the friction is large' and is liable to be blocked by the residue and the object. When the string is clamped, the needle has a flaw, and the needle is broken. There is also _ At Φϊ- T& * U rb -Htt- The disadvantage of the mouth is that the loading of the redundant string is complicated. The redundant string ▼ must be placed between the sprocket and the guide, and then rotated by the sprocket to send it to the cut-off device [this is particularly troublesome, because in the case of an embroidery machine, there are many sequins Must be placed. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device of the above kind which

= in the form of a rod or spring piece) the top pivots against the spring force. In the case where the β = is used, the material guide is in contact with the rear side of the string, and the rear side is used to lean against the side of the cloth after the sheet is trimmed. The disadvantage of suitable devices is that the coiling angle is too large, and if a part of the accurate bright moon string is easier to put in, the sequin string strap can be removed, the needle breaks, and the device is damaged. According to the present month, this is achieved by designing the guide member to move away from the front side of the strap and to move away from the sprocket, and to provide a force member that is held while the device is in operation. In the guiding position but in the event of the opposite force of the pre-twisting, there is no effect, so the guiding member can be lifted from the sprocket, unlike the prior art, in which the guiding member does not The strap is in contact with the rear side and is in contact with the front side of the strap. On this side, the needle is immersed in the aperture of each sequin during the embroidering. 1322206 This device allows the strap to be placed from the front by lifting the guide from the sprocket before the strap is placed. However, after the string is released, the guide member is held in the guiding position by the force member. If the string is clamped during operation, the guide is raised from the strap, with the result that the sprocket no longer transports the strap. This prevents the device from being damaged with the needle. In addition, a warning device can be actuated by the rise of the guide. Depending on the purpose, a stop can be provided which is in contact with the guide member in the guiding position. This prevents the guide member from being pressed against the string by the force member. The guide should preferably be designed as a pivoting lever. This allows the guide to pivot smoothly to fit into the ". The pivoting lever is preferably pivotally supported below the sprocket. This makes the structure very simple and the coil angle can be kept small: a magnet is used as a force element. The use of a magnet has the advantage that the guide member is held firmly by a large force only in the guiding position. Therefore, the leader can be lifted from the sprocket and left in this raised position when the string is clamped. The magnet should be placed on the free end of the pivoting lever in a usable-screw adjustment. The gap between the job and the guide can be adjusted by turning the screw. A fixed position guide is preferably provided behind the sprocket (downstream of the transport direction) and the string is brought to the cutting device. The invention also relates to an embroidery machine having a plurality of the above-described types of devices, wherein the sprocket is disposed on a common shaft that is coupled to a movable member that can be controlled by the control device of the machine, such as a servo motor. . Here, the shaft is preferably driven at its central position so that the torque received by the shaft can be kept small. 1322206 This cutting device should have a "strike plate", in which the cutting device has a variety of different design methods. A fixed "cut-off edge" and a movable movable plate can be actuated by the needle pusher. The strike plate can also be placed on the needle pusher. This can result in a particularly simple and inexpensive structure. An embodiment of the present invention will be described with reference to the drawings.
