Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

As shown in Fig. 1 to Fig. 4, a computer calculator 2 and a scanner 3 for recognizing barcodes of goods are provided at the checkout counter 1 installed at the exit of a department store or a supermarket. One side of the conveyor 10 is equipped with a system that supplies the goods automatically.

The conveyor 10 has a configuration in which a conveying belt 13 is installed outside the roller 12 mounted on both sides of the support frame 11, and the driving roller 12 on one side of the support frame 11 is a motor ( The belt 13 is rotated while being rotated by receiving the power of 12a).

A support plate 30 is installed at the bottom of the conveyor 10, and the legs 21 and 22 cross-coupled in an 'X' shape between the support frame 11 and the support plate 30 of the conveyor 10. Are installed facing each other.

At the intersection of the bridges 21 and 22 cross-linked in an 'X' shape, a support shaft 20 is installed therethrough, and these legs 21 and 22 are constituted in pairs so as to be provided at both sides of the support plate 30. It is installed to face each other is to be able to stably support the support frame 11 of the conveyor (10).

One side of the legs 21 and 22 is arranged on the lower side of the support frame 11 and the upper side of the support plate 30, respectively, and the rail grooves 21a and 22a on the other side of the legs 21 and 22. These slides are respectively coupled to the guide rails 21b and 22b mounted on the lower side of the support frame 11 and the upper other side of the support plate 30.

Therefore, since the legs 21 and 22 cross-coupled in the 'X' shape are folded around the axis 20 of the intersection, the conveyor 10 is stable by the cross-coupled legs 21 and 22. The structure is lifted in the state supported by the.

The operation of elevating the conveyor 10 while unfolding and folding the legs 21 and 22 is achieved by the elevating means 40, and the elevating means 40 can be variously implemented in different configurations. This will be described in detail as follows.

That is, as shown in FIG. 2, the lifting means 40 has a pulley 41a mounted on a rotation shaft of the forward and reverse rotation motor 41 mounted on one side of the support plate 30, and wound on the pulley 41a. Traction rope 42 is configured to be fixed to the support bar 23 mounted on the lower side between the legs 21 for the slide movement.

Lifting means 40 having such a configuration rotates the forward and reverse rotation motor 41 in one direction and rotates the pulley 41a while the tow line 42 is wound around the pulley 41a and the legs 21. Pulling the supporting rods 23 mounted therebetween, as shown in FIG. 5A, the legs 21 and 22 cross-coupled in an 'X' shape are pivoted upwards with respect to the axis 20 of the intersection. The conveyor 10 is raised.

On the contrary, when the forward and reverse rotation motor 41 is rotated in the opposite direction, as shown in FIG. 5B, the towing string 42 wound around the pulley 41a is released and the conveyor 10 descends by its own weight. The other side of the 21 and 22 slides outward.

Of course, the traction cord 42 is composed of a wire wire or chain, such as a very strong tensile strength is to be able to fully support the load of the conveyor (10).

And, as shown in Figure 3 the lifting means 40 is a screw rod 43 is coupled to the rotary shaft of the forward and reverse rotation motor 41 mounted on one side of the support plate 30, the front end is a slide movement It is a structure screwed to the nut 44 of the support rod 23 mounted below the legs 21.

Lifting means 40 having such a configuration is the screw rod 43 screwed to the nut 44 of the support rod 23 when the screw rod 43 rotates in one direction by driving the forward and reverse rotation motor 41. By pulling the supporting rods 23 mounted between the legs 21 by the rotation of the (), the legs 21, 22 cross-coupled in the 'X' shape is rotated upward with respect to the shaft 20 As the conveyor 10 is raised.

On the contrary, when the screw rod 43 is rotated in the opposite direction, the support rod 23 is pushed outward so that the other side of the legs 21 and 22 slides outward so that the conveyor 10 is lowered.

In addition, as shown in Figure 4, the lifting means 40 is mounted on the upper side between the legs 21, the front end of the piston rod (45a) of the cylinder 45 mounted on one side of the support plate 30 slides It is the structure built up in the support rod 23.

The lifting means 40 having such a configuration is pushed upward by the support rods 23 mounted between the legs 21 when the piston rod 45a is advanced by the operation of the cylinder 45. Conveyors 10 are lifted as the cross-coupled legs 21 and 22 are pivoted upward with respect to the shaft 20.

On the contrary, when the piston rod 45a is retracted, the support rod 23 is pulled downward so that the other side of the legs 21 and 22 slides outward so that the conveyor 10 is lowered. The cylinder 45 is composed of pneumatic and hydraulic cylinders operated by the force of an air compressor or hydraulic pump.

On the other hand, the rail groove (21a) coupled to the lower portion of the leg 21, the engaging rod (31a) is protruding and the switch 31 is mounted on both sides of the guide rail (21b) so that the leg 21 slides the rail groove ( As the engaging rod 31a of 21a operates the two-side switch 31 to automatically turn on and off the motor 12a, the stroke distance at which the other side of the legs 21 and 22 slides can be adjusted. have.

And, the operation of the forward and reverse rotation motor 41 and the cylinder 45 may be used by the operator to manually operate the switch, but by using a variety of sensors to detect the weight of the article or the size of the basket to be automatically operated It can be used in a variety of ways.

The present invention as described above, as the conveyor 10 is moved up and down by the operation of the lifting means 40 can automatically supply the goods to the scanner 3 side, so the bulky and heavy items or basket In the case where the height is formed high, the goods are transported while the conveyor 10 is lowered, and when the product is small and light or the height of the basket is low, the goods can be transported while the conveyor 10 is raised. As the height of the conveyor 10 is adjusted according to the weight of the article or the size of the basket, it is not only very convenient to use but also can increase the efficiency of the work. will be.
