This device combines the pneumatic system and the reciprocating engine to automatically fit the upper frame into the lower frame wearing socks, etc., and also to turn over socks etc. by mechanical tentacles linked with these. It is a type with a function to complete and to discharge the finished product.

The present invention is directed to a device for use in combination with the above apparatus for the automatic setting of the lower frame and the bilin on the frame upright, prior to the functioning of the apparatus.

(Prior Art) Even if there is a frame tensioning device for embroidery (hereinafter referred to as "upper frame tensioning device A") in which the fitting of the upper frame is labor-saving, the bilin and the lower frame are used as the lower frame fitting holes of the frame tensioning stand. Manual setting was still cumbersome, and there was a problem in workability.

(Problems to be Solved by the Invention) In view of such a situation, the present invention cuts bilinne one by one to a required length, sends it to the frame tension base together with the lower frame, and fits it into the lower frame fitting hole. It is intended to automate the operations up to.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an upper frame tensioning device A.
(Because the present invention is a device for setting the bilin and the lower frame on the frame tension base in the fixed state in the device A,
A detailed description of the structure of the device A is omitted), and a preliminary setting table 1 for combining a bilin and a lower frame is provided on one side.

Then, the preliminary setting table 1 is provided with a bilin guide groove 2 in a direction orthogonal to the frame tension table of the upper frame tensioning device A, and a bilin feeding mechanism 3 for feeding the bilin toward the guide groove 2 and a bilin. It is provided with a bilin cutter 4 that cuts to a required length.

In addition, a mechanism for delivering one lower frame is provided at a side portion of the preliminary setting table 1 with respect to the feeding direction of the bilin. The delivery operation is performed by a lower frame delivery reciprocating engine (not shown) provided in the preliminary setting table 1.

Further, above the preliminary setting table 1, a bilin vacuum 6 for adsorbing the delivered bilin and lower frame vacuums 7, 7 for adsorbing both ends of the delivered lower frame are continuously provided, and these are vertically moved integrally. A vertical reciprocating mechanism 8 is provided.

Further, the vertical reciprocating mechanism 8 is further projected to a position directly above the frame tensioning stand of the upper frame tensioning device A while the vacuums 6, 7, and 7 of the consecutively arranged attract the bilin and the lower frame to the vertical reciprocating mechanism 8. And a horizontal reciprocating mechanism 9 for

The operations of the respective parts are incorporated in the same command system of the automatic control mechanism.

(Operation) The present invention is configured as described above, and the frame tensioning base of the upper frame tensioning device A is now waiting for the bilin and the lower frame.
The operation will be described with the state shown in the figure as the starting point.
Bailin is paid out toward the guide groove 2 of the preliminary setting table 1 by a required size (Fig. 2A). Next, one lower frame is sent out from the orthogonal direction (Fig. 2B), the limit switch operates at the sending-out limit position, and the bilin vacuum 6 and the lower frame vacuums 7 and 7 are moved downward, so that the bilin B and the lower frame F respectively. Push in both ends of the (at this time, the vacuum still does not operate and only performs the pressing function) (Fig. 2C). Then, the bilin cutter 4 operates to cut the bilin in a predetermined size (Fig. 2D). Next, the vacuum works, the bilin vacuum 6 takes the bilin B, and the lower frame vacuum 7,
7 adsorbs both ends of the lower frame F, respectively, and at the next moment, the vertical reciprocating mechanism 8 operates and floats to a predetermined upper position in that state (Fig. 2E). Then, at the upper limit position, the limit switch operates to activate the horizontal reciprocating mechanism 9,
The vertical reciprocating mechanism 8 is projected to a position directly above the frame tensioning base of the upper frame tensioning device A (see FIG. 2). Finally, at the protruding extreme position, the limit switch is actuated to operate the vertical reciprocating mechanism 8, and the bilin vacuum 6 and the biframe B and the bottom frame F caught by the bottom frame vacuums 7 and 7 are fitted to the bottom frame of the frame mount. The next time, the vacuums 6, 7, and 7 stop sucking, the bilink B and the lower frame F are released, the vertical reciprocating mechanism 8 moves upward, and the horizontal reciprocating mechanism 9 operates and the vacuum is pushed into the hole. It moves back to its original position (Fig. 2).

Then, after that, the operation area of the upper frame tensioning device A is reached, and finally the product whose frame tensioning has been completed is discharged to the product storage box. The operation of the upper frame tensioning device A is not directly related to the present invention, and therefore its explanation is omitted.

(Embodiment) To explain with reference to an embodiment of the drawings, A in FIG. 1 is an upper frame tensioning device which the applicant has previously registered for a utility model, 101 is a device main body, and 102 is a workbench (frame tensioning platform). ),
