  In addition, the article loading device 1 receives and supports the article W falling from the drop opening 5 during support and temporarily stands by, and when loaded, the articles are placed in different directions so that the opposite end portions facing each other descend. Simultaneously turning downward, the article W is dropped into the container A stopped at the loading position on the container conveying means 6 and a pair of left and right turns guiding the falling article W to the container A from both the left and right sides. Support means 51 is provided. Further, the article loading device 1 is disposed between the opening / closing conveyance means 4 and the rotation support means 51, and guides the article W falling from the drop opening 5 from its periphery, that is, from both the left and right sides and both front and rear sides. The center of the article W placed in a predetermined position on the rotation support means 51 and the center of the container A stopped at the loading position on the container transport means 6 (the plan view of both the rotation support means 51). Positioning guide means 52 for matching the center) in plan view.

  Each of the rotation support means 51 can rotate about 90 degrees in the vertical direction about the axis 54 in the front-rear horizontal direction with respect to the machine frame 2, for example, and is supported in a substantially horizontal state by the upward rotation in which the opposite end rises. Thus, it is constituted by a rotating plate 55 that is a rotating body such as a substantially rectangular and substantially plate-like receiving plate that is turned into a substantially vertical state by downward rotation in which the opposite end portion is lowered.

  One end of a connecting arm 56 is attached to the end of each rotating plate 55 on the shaft 54 side, and the other end of the connecting arm 56 is a cylinder 57 that is a driving means for rotating the rotating plate 55 in the vertical direction. The rod portion 58 is attached to be rotatable. The rod portion 58 can be moved in and out of the cylinder main body 59 of the cylinder 57, and the cylinder 57 expands and contracts when the rod portion 58 moves in and out.

  Then, when the cylinder 57 is extended, both the rotating plates 55 are simultaneously rotated upward so that the opposite end portions on the distal ends facing each other about the base end side shaft 54 are raised, and the upper side from the inside of the container A is raised. Then, in the vicinity of the lower end of the positioning guide means 52, a substantially horizontal support state substantially in the horizontal direction is obtained. At this time, the tip portions that are opposite ends of the substantially horizontal rotating plates 55 are substantially in contact with each other. On the other hand, when the cylinder 57 is contracted, both the rotating plates 55 simultaneously rotate downward and enter the container A so that the opposite ends on the distal ends facing each other about the shaft 54 on the proximal end are lowered. In the container A, a substantially vertical charging state is obtained that is substantially along the vertical direction, that is, substantially along the inner surface of the side plate portion A3.

  As shown in FIG. 5 and the like, the positioning guide means 52 is a four-sided mortar capable of shaping the article W in a substantially cylindrical shape that is fixed to the machine frame 2 and whose upper and lower surfaces are open and in a substantially inverted truncated quadrangular pyramid shape. It is constituted by a guide cylindrical body 61 such as a guide.

  The guide cylindrical body 61 is formed in a substantially cylindrical shape with an upper and lower surface opening having a substantially rectangular upper surface opening 62 and a substantially rectangular lower surface opening 63 smaller than the upper surface opening 62. The lower surface opening 63 is opened and closed by the left and right rotating plates 55, and the longitudinal dimension (length dimension in the left and right direction) of the lower surface opening 63 is smaller than the longitudinal dimension (length dimension) a of the article W. The short side dimension (front-rear direction length dimension) of the lower surface opening 63 is substantially the same as the short dimension (width dimension) b of the article W.

  Further, the guide cylinder 61 is formed in a substantially trapezoidal shape that is positioned so as to be spaced apart from each other and gradually contracted downward, and guides both ends in the longitudinal direction of the article W. , 65, and a pair of front and rear inclined plate portions 66, 67 that are positioned so as to be opposed to each other and that are formed in a substantially trapezoidal shape that gradually decreases in width toward the lower side and guides both ends in the short direction of the article W. Have. A slender mounting plate 68 is integrally provided on each of the upper end portions of the inclined plate portions 64, 65, 66, 67, which are the four inclined surface portions, and each of the mounting plate portions 68 is attached to the machine frame 2. It is fixedly attached to the part with a fixture 69 such as a bolt.

  As shown in FIG. 1 to FIG. 3, a control means 70 such as a control panel for controlling the driving means of each conveying means 3, 4, 6 and each cylinder is provided at the front of the machine frame 2. ing.

  Next, the operation of the article input device 1 will be described with reference to the drawings.

  As shown in FIGS. 6 (a) and 6 (b), the article W having a substantially rectangular shape in plan view was placed on the conveying means 3 so that the longitudinal direction thereof coincides with the left-right direction of the article input device 1. In this state, the sheet is conveyed rightward by the conveying unit 3 and temporarily stops at the article standby position on the conveying terminal side of the conveying unit 3.

  Then, when the open / close conveying means 4 is closed and the opening / closing means 5 is closed by the open / close conveying means 4 and there is no article W at the article stop position on the open / close conveying means 4. 7 (a) and 7 (b), the article W is further conveyed in the right direction by the conveying means 3 and transferred onto the opening / closing conveying means 4, and thereafter the article W is opened by both opening / closing conveying means 4. Until the stop position, that is, until the front surface of the article W in the conveyance direction comes into contact with the stopper plate portion 26 of the stopper means 25, the article W is conveyed rightward.

  In the vicinity of the stopper means 25, an article presence / absence detecting means (not shown) such as a photoelectric switch for detecting whether or not the article W is present on the open / close conveying means 4 is disposed. After the detection, the opening / closing conveying means 4 stops operating after the elapse of a predetermined time, and the article W stops at the article stop position. For this reason, the article W is not in a state where the front surface in the conveyance direction is strongly pressed against the stopper plate portion 26, but in a state where the front surface in the conveyance direction is in light contact with the stopper plate portion 26, and the left half is the open / close conveyance means on the left side. 4 and the right half is located on the right open / close conveying means 4, the bag core of the bag, which is the article W, coincides with the input core.

  In addition, in the case where the operation of both the open / close conveying means 4 is stopped after a lapse of a predetermined time from the timer after the front surface in the conveyance direction of the article W comes into contact with the stopper plate portion 26, There is a possibility that the front end side in the conveyance direction of the article W is greatly deformed by contact with the stopper plate portion 26 and the posture of the article W is deteriorated.

  Further, as shown in FIG. 7 (b), the stopper plate 40 of the standby position stopper means 36 is lowered and retracted from the moving area of the container A, so that one container A is cut off. The container A is conveyed rightward by the container conveying means 6 to the loading position on the container conveying means 6, that is, until the front surface of the container A in the conveying direction comes into contact with the stopper plate 43 in the advanced state. At this time, both rotating plates 55 are in a substantially horizontal support state so as not to interfere with the container A being conveyed.

  Next, both the rotating plates 55 are in a substantially horizontal support state, and the lower surface opening 63 of the guide cylindrical body 61 is closed by these rotating plates 55, and the both rotating plates 55 are placed on the rotating plates 55. If there is no article W and the article presence / absence detecting means (not shown) such as a photoelectric switch detects the absence of the article, as shown in FIGS. 8 (a) and 8 (b), the article W When the opening / closing conveying means 4 is separated from each other and the drop opening 5 is opened, the drop opening 5 is dropped from the drop opening 5 onto both rotating plates 55 in a substantially horizontal support state.

  At this time, the conveyance belt 16 of the left opening / closing conveyance means 4 rotates forward in the same manner as the conveyance described above, but the conveyance belt 16 of the right opening / closing conveyance means 4 reversely rotates so that the bag core does not shift from the insertion core. Note that if the opening / closing conveying means 4 is released in a state where the rotation of the conveying belt 16 is stopped, the article W may be pulled by either one of the both opening / closing conveying means 4 and the bag core and the input core may be misaligned. .

  The article W dropped from the drop opening 5 is guided from four directions by the four inclined plate portions 64, 65, 66, 67 of the guide cylindrical body 61, and is placed at a predetermined position on the both rotation plates 55. Both ends in the longitudinal direction are substantially V-shaped deformed upward, and are located at the lower inner side of the guide cylindrical body 61.

  In this state, the article W on both the rotating plates 55 is coincident in plan view with the center P in plan view of the container A stopped at the loading position on the container transport means 6. That is, for example, even if the article W is slightly deviated from the proper article stop position on both the open / close conveying means 4, the misalignment is corrected by the guidance by the guide cylindrical body 61, and the article W is placed on the both rotating plates 55. It will be located at an appropriate predetermined position.

  An article presence / absence detection means (not shown) such as a photoelectric switch for detecting whether or not an article W is present on the rotation plate 55 is disposed in the vicinity of the rotation plate 55. When the presence of the article is detected, the drop is completed, and both the opening and closing conveyance means 4 approach each other to close the drop opening 5 and enter a closed state in which the next article W can be received.

  Then, as shown in FIGS. 9A and 9B, when both open / close conveying means 4 are closed, the next article W is carried from the conveying means 3 to the article stop position on the open / close conveying means 4. Note that the completion of closing of the opening / closing conveyance means 4 is confirmed by a cylinder reed switch.

  At this time, when the container A into which the article W is to be placed has not arrived at the placing position on the container transporting means 6, two articles W wait on the placing core (see FIG. 9B).

  On the other hand, if the container A into which the article W is to be loaded has arrived at the loading position on the container transport means 6, the article W is moved by the operation of the cylinder 57 as shown in FIGS. 10 (a) and 10 (b). When the rotating plate 55 is simultaneously rotated downward to open the lower surface opening 63 of the guide cylindrical body 61, it is dropped into the container A from the lower surface opening 63 through the upper surface opening A1.

  At this time, both the rotating plates 55 enter the container A from the upper surface opening A1, and the both ends in the longitudinal direction of the falling article W are smoothly guided by the entering both rotating plates 55. It is not caught on the upper end of the side plate portion A3 of A.

  Next, as shown in FIGS. 11 (a) and 11 (b), after the article W has been put into the container A, both the rotating plates 55 are simultaneously rotated upward by the operation of the cylinder 57 to guide the cylindrical body 61. The lower surface opening 63 is closed, and a support state in which the next article W can be received is obtained.

  When the closing completion of the rotating plate 55 is confirmed by the cylinder reed switch, the stopper plate 43 of the stopper member 37 for loading position is lowered and the actual container A is carried out to the actual container discharging means by the container conveying means 6. At the same time, the stopper plate 40 of the standby position stopper means 36 is lowered and the next empty container A is conveyed by the container conveying means 6 to the loading position.

  By repeating such an operation, the articles W are sequentially put into the container A one by one, and the actual containers A into which the articles W are put are sequentially carried out to the actual container discharging means.

  And according to this article | item throwing-in apparatus 1, the article W which receives and supports the article W which falls from the drop opening part 5 between the paired opening / closing conveyance means 4 is supported, and the article W is placed on the container conveyance means 6 by rotating downward at the time of loading. Since the rotating plate 55 which is the rotation support means 51 which makes the pair falling in A and guiding this falling article W into the container A is provided, the article W is placed on the upper end of the side plate portion A3 of the container A. The article W can be appropriately put into the container A in a desired posture without being caught, and the article W can be reliably put into the container A regardless of the fluidity of the contents of the article W.

  For example, the container A may be covered with an inner bag such as a resin bag and the article W is put into the inner bag. Even in this case, the article W is appropriately put into the inner bag in a desired posture. it can.

  Furthermore, since the guide cylinder 61 which is the positioning guide means 52 for guiding the article W falling from the drop opening 5 and positioning the article W at a predetermined position on the both rotation support means 51 is provided, The article W can be aligned with the container A stopped at the loading position, and the article W can be more appropriately thrown into the container A.

  Further, since the articles W can be placed in the vertical direction at the position on the open / close conveying means 4 and the position on the rotation support means 51, respectively, the loading time of the articles W into the container A can be shortened, and the work efficiency can be reduced. Improvement can be achieved, and two articles W can be put into one container A at the same time.

  Furthermore, a lifting device that lifts and lowers the container A is unnecessary, and the configuration can be simplified.

  In the above-described embodiment, the description has been given of the configuration including the pair of left and right rotation support means 51 that can vertically rotate the article W into the container A from both the left and right sides. In addition, a configuration may be provided that includes a pair of front and rear rotation support means that can guide the article W into the container A from both front and rear sides and that can rotate in the vertical direction. It consists of a moving plate.

  Further, for example, a configuration including a guide frame that contacts the side surface in the conveyance direction of the article W in the middle of conveyance by the conveyance means 3 or a cylinder rod on the side surface in the conveyance direction of the article W in the middle of conveyance by the conveyance means 3. It is also possible to adopt a configuration including a cylinder-type centering device that contacts and centers the article W.

  Further, for example, when the contents of the article W are hardened and there is no fluidity, the article W may be clogged with the guide cylindrical body 61, but such a malfunction does not occur. Thus, for example, a vibration conveyor having a vibration device may be disposed on the upstream side of the conveying means 3 to loosen the contents of the article W.

  Further, for example, in order to prevent a problem that the article W having poor fluidity is clogged with the guide cylindrical body 61, a configuration including a vibration unit that vibrates the guide cylindrical body 61 in the left-right direction may be used.
