In the loading apparatus according to the present invention, the loader unit 110 is a portion for sliding the chemical drum 1 into the predetermined internal space of the frame unit 100 and then loading the chemical drum container 1 into the proper position A sliding portion 111, a rotation portion 112, and a lift portion 113 as shown in FIGS. 3 and 4.

The sliding part 111 is formed of a plurality of rollers 111a which are arranged so as to be capable of rolling in a direction in which the chemical drum container 1 is linearly moved with respect to the inner space of the frame unit 100. [ The plurality of rollers 111a constituting the sliding part 111 are arranged in parallel to each other at regular intervals and configured to roll in the linear movement direction of the chemical drum container 1. [ Each of the rollers 111a may be configured as an idle type having no driving force, or alternatively may be configured to be connected to a predetermined driving motor so as to have rotational driving force. When the chemical drum container 1 is completely pushed into the internal space of the frame unit 100, the chemical drum container 1 is held by the sliding portion 111 as shown in Fig.

[ At least some of the plurality of rollers 112a constituting the rotation unit 112 are arranged obliquely at an angle with respect to the direction in which the chemical drum 1 is moved in and out, 1). In order to rotate the chemical drum container 1 in a stably supported state, it is preferable that the rollers 112a arranged at an angle are disposed at four positions on the circumference of the chemical drum container 1 at mutually equal intervals. In addition, it is advantageous from the viewpoint of space utilization that the rollers 112a arranged in an inclined manner are disposed so as to be raised and lowered in the region of the sliding portion 111. [ 3, the sliding portion 111 is formed by at least four holes in total by a combination of a roller having a relatively long length and a roller having a relatively short length, and the roller (not shown) 112a are elevated and lowered.

The elevating part 113 lifts the chemical drum container 1 pushed into the internal space of the frame unit 100 by the sliding part 111 from the sliding part 111 and separates the chemical drum container 1 from the sliding part 111 The chemical drum container 1 is switched to a state capable of freely rotating in the circumferential (circumferential) direction. The elevating portion 113 may be constituted by a predetermined pneumatic cylinder. Alternatively, the elevating portion 113 may be constituted by a predetermined hydraulic cylinder.

The elevating part 113 is assembled to the lower part of the rotation part 112 so as to vertically move the rotation part 112 in the vertical direction with respect to the sliding part 111. The chemical unit 1 is loaded on the sliding part 111, From the sliding portion 111, as shown in Fig.

It is possible to rotate the chemical drum container 1 at a predetermined angle by driving the roller 112a of the rotation section 112 in this state. The rotation unit 112 may be provided with two driving rollers 112c connected to the driving motor 112b to actively rotate. In order to provide a balanced driving force, it is preferable that the two driving rollers 112c and the driving motors 112b corresponding to the two driving rollers 112c are arranged symmetrically with respect to the center of the rotation part 112. [ In this case, the chemical drum container 1 is rotated while being supported by a total of six rollers 112a and 112c. Here, the gap between the adjacent rollers is relatively large, so that at least two holes are formed in the sliding part 111, and the driving roller 112c is moved up and down through the hole.

Fig. 7 shows the construction of an automatic coupling system for automatically performing opening and closing operations and coupling operations automatically with respect to the cap 2 of the chemical drum container 1.

The aligning jig 140 is swung up and down by the up-down cylinder 143 together with the swing by the rotary cylinder 142 to position the cap stopper 141 at a predetermined point. The chemical drum container 1 is rotated by the rotation portion 112 of the loader unit 110 and aligned in the position where the discharge port, that is, the portion of the cap 2, contacts the cap stopper 141. When the chemical drum container 1 is aligned in the correct position by the aligning jig 140, the coupler unit 130 and the opening and closing unit 120 can be accurately aligned in order at the discharge port.

11 (a) to 11 (c), the cap 2 of the chemical drum 1 is brought into contact with the cap stopper 141 of the aligning jig 140, Is shown. As shown in the drawing, the aligning jig 140 is reciprocally moved in the left and right directions between the chemical drum containers 1 supplied to the two loader units 110 to carry out the alignment function alternately. That is, as shown in Fig. 11 (a), alignment is performed by contacting the cap 2 of one of the chemical drum containers 1 by turning to the first position, and then, 11 (c), it is rotated to the second position and brought into contact with the cap 2 of the newly supplied other chemical drum container 1 to perform alignment. If one alignment jig 140 is arranged to be shared by the chemical drum containers 1 on both sides, it is possible to arrange one of the chemical journals 140 on the other chemical drum container 1 during the alignment operation of one of the chemical drum containers 1, (2) can be opened and the coupling operation can be performed, so that the productivity can be maximized.

The coupler unit 130 has a coupler 131 which is inserted into the discharge port in a state in which the cap 2 of the chemical drum container 1 is opened.

The loader unit 110, the opening and closing unit 120, and the coupler unit 130 are sequentially controlled by a control unit (not shown) programmed in advance according to a predetermined algorithm.

The carriage 200 has a drum transfer unit 201 for loading and unloading the chemical drum into and from the frame unit 100 with respect to the loader unit 110 as well as a mounting space in which the chemical drum 1 can be loaded. The drum conveying unit 201 is preferably configured such that a plurality of rollers are arranged so that the chemical drum container 1 is slid in and out of the frame unit 100. However, Of course not.

In addition, the bogie 200 may be equipped with a push member of a predetermined shape for performing an operation of pushing the chemical drum container 1 into the internal space of the frame unit 100. [ The push member is driven by a pneumatic cylinder and is installed in the bogie 200 so as to be able to move forward and backward.

The bogie 200 may be controlled by bidirectional communication with the control unit and may be set to reciprocate between a predetermined chemical drum supply unit and the loader unit 110. As the bogie 200, an unmanned electric bogie is preferably employed, but a manual bogie may be employed depending on the working conditions.
