 BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated in the following-in detail according to an embodiment. 1, 2, and 3 are a side view of the present invention, a sectional view taken along line II-II in FIG. 1, and a sectional view taken along line III-III in FIG. As shown in FIGS. 1, 2, and 3, a transferred object transfer device is installed at one end of a transfer path of a traverse type loader capable of traveling above a machine tool. The transferred object transfer device includes a table 1 on which a transferred object such as a work W is placed, which can be moved up and down, a chute 2 for transferring the work W on the table 1 to a belt conveyor 4, and an outlet for the chute 2. It is equipped with a gate stopper 3 that opens and closes.

The table 1 mainly comprises a pair of support plates 10 in the axial direction of the work W, a guide member 11 extending below the work W in parallel with the work W, and an upper end of the guide member 11 connected to the work W. The cylinder 13 is composed of a pair of support rods 12 in the axial direction of W, and is vertically moved by a cylinder 13 fixed to a support frame 51. The support rod 12 is supported by the guide sleeve 15 fixed to the support base 51 so as to be able to move up and down, and the tip of the piston rod 13a of the cylinder 13 is connected to the center of the connecting member 16 that connects the lower end of the support rod 12. To be done. Further, a coil spring 17 is attached to the support rod 12 to urge the guide member 11 upward, and a stopper 18 attached to the support pedestal 51 restricts the rise of the connecting member 16 to drive the cylinder 13 of the pedestal 1 to an upper limit. The position is set.

The support plate 10 has a V-groove 10 a on which the work W is engaged, and an end face plate 22 for positioning the work W in the axial direction is attached to the outer surface of the support plate 10. Further, the support plate 10 can be vertically adjusted according to the diameter of the work, and can be horizontally adjusted according to the length of the work. That is, the guide member 11 has a T-shaped cross section, and a slider 19 having a T groove in the lower portion is slidably mounted on the guide member 11, and a pair of guide pins 21 and a central adjusting screw 20 are interposed in the slider 19. The base portion 10b of the support plate 10 is attached. When the adjusting screw 20 is rotated according to the workpiece diameter, the support plate 10 is vertically moved by being guided by the guide pin 21, and the set screw 20a provided on the base portion 10b of the supporting plate 10 is pressed against the adjusting screw 20 to support the supporting plate. 10 is fixed to the slider 19 and adjusted so that the center of the work W is always located at a constant height. In the axial direction of the work W, one or both sliders 19 are moved according to the work length, and the slider 19 is fixed to the guide member 11 by the bolts provided on the slider 19.

The chute 2 has an inclined surface 25 a that slopes downward toward the unloading side, and a pair of chute plates 25 disposed inside the support plate 10 in parallel with the work transfer direction, and this shoot plate. A chute plate base portion 25b at the lower part of the carry-in side of 25 is guided and supported by a pair of upper and lower bars 26 inserted through the chute plate base portion 25b, and the position of the work W can be adjusted in the axial direction. The inclined surface 25a of the chute plate 25 has its work transfer portion located below the V groove 10a at the upper limit position of the support plate 10 and above the V groove at the lower limit position of the support plate 10, and then descends from the table 1. The upper work W is received and can be transferred to the belt conveyor 4 side. The gate stopper 3 is installed above the unloading side of the chute 2, and extends along the axial direction of the work W. The gate plate 30 and the rotary rod whose both ends are rotatably supported by the support member 53. 1, the gate plate 30 rotates counterclockwise in FIG. 1 to close the carry-out port of the chute 2 in a vertical state, and from this state, rotates 90 degrees in a clockwise direction to shoot in a horizontal retracted state. It is designed to open the 2 outlet.

An L-shaped link 35 is arranged on one of the side surfaces of the transferred object transfer device parallel to the transfer direction of the transferred object, and the link 35 allows the guide member 11 of the mounting table 1 and the gate stopper to be connected. By connecting the rotating rod 31 of No. 3 to the raising / lowering operation of the stand 1, the opening / closing operation of the gate stopper 3 can be interlocked. The link 35 has two link members 35a and 35b that are substantially orthogonal to each other, and the center portions of the link members 35a and 35b are pivotally attached to the support member 53 so as to be rotatable in a vertical plane. For this shaft attachment, as shown in FIG. 3, for example, a sleeve 36 is fixed in a mounting hole of a link 35, and a shaft 38 is rotatably supported in the sleeve 36 via bearings 37, 37. A nut 39 is screwed and fixed to the tip. The link 35 and the guide member 11 are connected by a connecting plate 42 attached to the end surface of the guide member 11, a cam follower 41 attached to the lower portion of the connecting plate 42, and a cam follower 41 formed at the tip of the link member 35a. The long hole 40 is used. The long hole 40 is formed long in the longitudinal direction of the link member 35a so that the displacement of the tip end portion of the link member 35a with respect to the cam follower 41 due to the rotation of the link member 35a can be absorbed. The connection between the link 35 and the rotating rod 31 is also formed at the operating lever 32 having a base attached to the end surface of the rotating rod 31, the cam follower 33 attached to the outer surface of the distal end of the operating lever 32, and the tip of the link member 35b. This is done by the long hole 34 into which the cam follower 33 is inserted. The elongated hole 34 is also formed to be long in the longitudinal direction of the link member 35b so that the displacement of the cam follower 33 due to the rotation of the link member 35b and the operating lever 32 can be absorbed. In addition, each member is set so that the gate plate 30 can rotate 90 ° with one stroke of the cylinder 13, and the operating lever 32 is rotated so that the gate plate 30 is positioned at the horizontal retracted position at the upper limit position of the mounting table 1. Set to 31.

The above-described configuration operates as follows. The stand 1 is in a raised position and the gate stopper 3 is open in a standby state for receiving a work, and the support plate 10 of the stand 1 and the chute plate 25 of the chute 2 are adjusted in position according to the work diameter and work length. .. In this state, for example, the work W transported in the air by a traverse type loader is placed on the V groove 10a of the pair of support plates 10. When the piston rod 13a of the cylinder 13 is moved in the contracting direction, the table 1 is lowered and the work W is transferred onto the chute 2. The transferred work W is transferred downward along the chute 2. At the same time, the link 35 rotates in the clockwise direction in FIG. 1, the horizontal movement of the link member 35b toward the mounting table causes the operating lever 32 to rotate 90 °, and the gate stopper 3 moves vertically from the opened state of horizontal standby. The work W transferred on the chute 2 comes into contact with the gate plate 30 and stops. Next, when the next work is conveyed from the previous process, when the piston rod 13a of the cylinder 13 is moved in the extension direction, the stand 1 returns to the raised position, and at the same time, the link 35 reverses to the opposite direction. When the gate stopper 3 is rotated clockwise, the vertical stop state is changed to the horizontal standby open state, and the stopped work W is rolled and transferred onto the belt conveyor 4. By repeating the above operation, the work W is transferred from the loader onto the belt conveyor 4 at an appropriate timing and carried out to the next process. As described above, by mechanically connecting and interlocking the mounting table 1 and the gate stopper 3 with the link 35, only one driving body is required, and a control device for performing a sequence operation is not required, and a failure can occur. Performance can be significantly reduced, and the reliability of transfer operation is increased. Further, the device can be made compact as compared with the case where two driving bodies are installed. Furthermore, equipment costs, maintenance costs, etc. can be reduced, and an inexpensive device can be obtained. The transfer device between the traverse type loader and the belt conveyor has been described above, but the transfer device is not limited to this and is an apparatus that transfers between two transfer means or between the machine tool and the transfer means.
