And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

Referring to the operation of the invention monorail automated conveying device configured as described above are as follows.

The present invention loads the package on the lowered carrier 50 as shown in Figs. 2 and 3 (a) (b) and then raises the carrier 50 as shown in Fig. 4 (a) (b). By moving to the position, the section control system (controller for operation management control mounted in the carrier tank board) of the control unit 2 is usually composed of 6 to 8 lines in a manner of traveling by instruction from the ground control panel, 2 ~ 4 wires and communication lines) and self-driving control system (with the various sensors and controllers for storage and storage control in the carrier tank, the carrier body itself controls acceleration / deceleration or exact position) It is possible to make sure that the accumulator stops and set the speed according to each production process, and to perform ascending and descending through communication from the ground by optical transmission device or communication board. .

That is, as shown in FIGS. 2 and 3, the supporting part 60 folded at the lower end of the body 51 is unfolded by the driving of the motor 68. When the motor 68 rotates forward, the supporting part 60 ) Is unfolded, and the support unit 60 is folded when the motor 68 reverses. That is, the support 60 is unfolded by the forward rotation of the motor 68 because the operation arm 62 of one side connected to the lower end of the motor 68 rotates, and the operation arm 62 of the one side is rotated. When rotated, the round bar 63 connected to the hinge shaft 66a is pushed out while pushing the operation arm 61 on the other side. At this time, the opening angle of the operating arms 61 and 62 is adjustable, and when the adjusting bolts 65 and 65a provided at both ends of the round bar 64 are reversely rotated, the operating arm is operated by the left and right screws. It is possible to adjust the opening angle of the 61 (62).

In more detail, the present invention is provided with a positioning detection unit 80 on one side of the upper body 51 of the operating arms (61, 62) to determine the drive and angle of the operating arms (61, 62). By adjusting, when the cam 81 rotates forward and reverse as the operating arms 61 and 62 rotate, the switch 82 is selectively touched, which controls the driving of the motor 68 and consequently operates. The drive and angle of the arms 61 and 62 are adjusted.

As described above, when the working arms 61 and 62 are accurately positioned at the bottom of the package, the carrier 50 is lifted by lifting the package 50 as shown in FIG. 4.

That is, when the reducer 22a is driven by the driving of the motor 22, the shaft 23 connected to the reducer 22a rotates, and the inner and outer belts provided at both ends are rotated by the rotation of the shaft 23. The windings 24 and 25 rotate. At this time, the belt 26 of the inner belt winding 24 is fixed to both sides of the lower side of the one side of the carrying section 50, the belt 26 of the outer belt winding portion 25 of both sides of the other bottom of the carrying section 50 By the fixed rotation of the shaft 23, the inner and outer belt windings 24 and 25 rotate at the same time while the belt 26 is wound so that the carrying unit 50 rises, and the shaft 23 By the reverse rotation of the belt 26 is released while the conveying unit 50 is lowered.

According to the present invention, if the belt 26 is broken by the operation of the safety device 30, the lifting and lowering transfer part 20 is prevented from falling.

That is, when the carrying unit 50 is raised to be positioned at the lower end of the body 21, the locking piece 34 protruding at the upper end of the body 51 protrudes into the center of the body 21. Then, the link 32 is rotated by the driving of the motor 31, and by the operation of the link 32, the locking hole 33 is moved to one side to the hole 34a of the locking piece 34. Will be fitted.

When the engaging piece 34 is fitted in the hole 34a as described above, even if the belt 26 is broken, the engaging piece 33 is caught by the engaging piece 34, so the lifting and lowering transfer part 20 Since it does not fall, it is possible to prevent a safety accident in advance.

And the present invention is because the upper position fixing pin (27a) protruding on the upper end of the body 51 is inserted into the position fixing portion (27) provided at the lower end of the body (51), The transport unit 50 is located at the lower end of the body 21 exactly.

In addition, the present invention is to unwind and wind the cable 41 wound on the cable winding 40 as the shaft 23 rotates forward and backward.

That is, when the drive wheel 42 is rotated by the rotation of the shaft 23, the drive chain 43 connected to the drive wheel 42 is driven to rotate the cable winding 40, the cable winding The cable 41 wound on the mounting portion 40 serves to send a signal to the control unit 41 from the ground by the adjustment unit not shown in the drawing.

And the present invention is provided with a belt break detection unit 70 at each lower portion of the inner and outer belt winding unit 24, 25, the belt 26 is broken when it detects this signal immediately after the signal to the control unit (2) To stop the whole machine from running.

That is, as shown in FIG. 10, the roller 71 is pushing the belt 26 in a tensioned state with a certain force by the compressed repulsive force of the spring 75 installed on the outer circumferential surface of the shaft 74. To be.

In this state, if the belt 26 is broken, the roller 71 pushing the belt 26 is moved to the right in the drawing due to the repulsive force of the spring 75. When the belt 26 is broken by the movement of the component, the proximity sensor 77 immediately sends a signal to the control unit 2 to control the driving of the entire equipment to be stopped.

On the other hand, as described above, when the conveying unit 50 is driven by the driving of the inner and outer belt windings 24 and 25, the conveying unit 50 is moved to one side by the driving of the driving unit 10.

That is, when the central roller 12b is rotated by the drive of the motor 11, the roller 12a, 12c provided in the bracket 15 rotates, and the driving drive part 10 moves the upper surface of the rail 1 with the rotation. Will be moved to one side.

In this case, in the process of moving the driving unit 10 along the rail 1, the dust removing unit 16 with the brush 16a removes the dirt on the rail 1, so 10) works smoothly.

Meanwhile, the present invention allows the lower portion fixing pin 56 provided to protrude to the lower side of the body 51 in the process of lowering the conveying portion 50 to be inserted into a separate insertion hole so that the conveying portion 50 is correctly lowered. Will be done.

In addition, the present invention is able to count the number of times the carrying unit 50 is lowered. That is, when the operating rod 53 descends and touches the floor, the operating rod 53 is pushed up to raise the cap 55 provided at the top of the operating rod 53, and as the cap 55 rises, The upper limit switch 52 is pushed to operate. When the operating rod 53 is pressed, the spring 54 installed on the outer circumferential surface thereof is compressed. In this way, when the operating rod 53 is pressed and then the carrying unit 50 is raised again, the operating rod 53 is lowered to the initial state by the repulsive force of the spring 54, and the counting is performed while this operation is repeated. Done.

As described in detail above, the present invention provides a control unit for controlling the driving unit moving along the rail, the monorail-type automated transporting device, and the lifting and lowering unit for moving up and down by the operation of the driving unit. It is equipped with a conveying unit for moving the package by means of a section, and the section control system and the self-driving control system are introduced to enable the accurate accumulator stop and the speed setting for each production process, and from the ground by the optical transmission device or the communication board. Ascending and descending through communication, and the height of the package can be adjusted to the desired height to improve the work efficiency, which is a very useful invention that can significantly improve the quality and reliability of the product .
