Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for keeping a basket on a basket conveyor circulating in a vertical plane in a vertical state at all times.

[0002]

[Prior art]

 Conventionally, as shown in FIGS. 5 and 6, a basket conveyor has a first chain 13 hung on a pair of first sprockets 11 and 12 and a pair of second sprockets 14 and 15 on the other side. The basket 19 is hung between the delivered second chain 16.

The basket conveyor 10 circulates while maintaining the basket 19 in a vertical state so that, for example, books stored in the basket 19 do not jump out of the upper portion of the basket 19 and fall, and the basket conveyor 10 is illustrated at a desired position. The bottom lid 20 is opened by the bottom lid opening / closing device, and the books are sorted and dropped. In the present invention, the "vertical state of the basket" means a state in which the bottom lid portion of the basket is directed downward.

Therefore, the first and second sprockets 11, 12, 14, and 15 are displaced from each other in the horizontal direction by the length of the diameter D of the first and second sprockets, and the basket 19 is It is connected to the first and second chains 13 and 16 at two diagonal portions (portions designated by reference numerals 17 and 18).

[0005]

[Problems to be solved by the device]

 However, such a basket conveyor has a problem that it requires a large space in the sprocket arrangement direction because the first and second sprockets have to be displaced from each other by the length of the diameter. . Further, since the basket has to be connected to the chain at two diagonal portions, there is a problem that the suspended state of the basket is unstable.

[0006]

[Means for Solving the Problems]

 The present invention is a basket conveyer in which a basket having an openable / closable bottom lid that is swingably suspended by a chain that is meshed with a pair of sprockets circulates in a vertical plane, and is provided integrally with the basket. And a horizontal arm that extends horizontally from the position where the basket is suspended in the chain, and a horizontal arm that is separated from the pair of sprockets in the direction in which the horizontal arm extends by the length of the horizontal arm and that rotates in a vertical plane. A possible pair of guide discs, a plurality of notches formed on the outer periphery of the guide disc at equal intervals and with which the tips of the horizontal arms engage, and between the pair of guide discs above and below the chain. The above-mentioned problems are solved by a device having a guide rail that is provided along the guide rail and that guides the tip of the horizontal arm.

[0007]

[Action]

 The chain moves the basset while being circularly moved by the rotation of the pair of sprockets. As the basket moves between the pair of sprockets, the tip of the horizontal arm moves within the guide rail. The horizontal rail is restricted from swinging in the vertical direction by the guide rail. This keeps the basket in a vertical position at all times.

As the basket moves along the pair of sprockets, the tip of the horizontal arm engages a notch in the guide disc. As the basket moves, the horizontal arm rotates the guide disc. The horizontal arm moves while engaging with the guide disc. This keeps the basket in a vertical position. In this way, the basket is constantly kept in the vertical state and circulated.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The basket conveyor (see FIG. 1) 30 has a first chain 33 that is stretched around a pair of first sprockets 31 and 32, and a first chain 33 that is stretched around another pair of second sprockets 34 and 35 (see FIG. 2). It is composed of two chains 36, a basket 40 suspended from the first and second chains 33 and 36 by slats 37 and 37 (see FIG. 3), and a pair of support shafts 38 and 39.

The support shafts 38 and 39 are supported by bracket links 41 and 42 (see FIGS. 3 and 4) provided in place of the outer link plates of the first and second chains 33 and 36. The bottom of the basket 40 is opened and closed by a bottom cover 43 (see FIG. 1). Each basket 40 is provided with a known bottom lid opening / closing device 44 for opening and closing the bottom lid 43.

The basket vertical maintaining device 50 is composed of a horizontal arm 51, a guide roller 52, a pair of guide disks 55 and 56 having notches 53 and 54, guide rails 60, 61, 62 and 63. There is. The guide rail 63 is not shown because it appears to overlap the guide rail 62 in FIG. One end of the horizontal arm 51 is provided integrally with the support shaft 38, and a guide roller 52 is rotatably provided at the other end of the horizontal arm 51. The horizontal arm 51 extends horizontally from the support shaft 38 to the right in FIG. The horizontal arm 51, the support shaft 38, and the basket 40 are integrated.

The pair of guide discs 55 and 56 are rotatably installed in a vertical plane at positions separated from the pair of sprockets 31 and 32 in the right direction in FIG. The distance L1 between the sprockets 31 and 32 and the guide disks 55 and 56 is the same as the distance L2 (horizontal arm length) from the support shaft 38 to the rotation shaft 57 of the guide roller 52. A plurality of notches 53, 54 are formed at equal intervals on the outer circumference of the guide disks 55, 56 so that the guide rollers 52 on the horizontal arm 51 are engaged.

The guide rails 60 and 61 are provided between the pair of guide discs 55 and 56 along the upper and lower sides of the first chain 33, and guide the guide rollers 52. The guide rails 60 and 61 are configured so that the traveling roller 64 on one of the support shafts 38 also travels. The other guide rails 62 and 63, which are parallel to the guide rails 60 and 61, allow the traveling roller 65 on the other support shaft 39 to travel. Both guide rails 60, 61, 62, 63 are formed in a U-shaped cross section.

Next, the operation will be described. The first and second chains 33, 36 move the basket 40 while being circulated by the rotation of the first and second sprockets 31, 32, 33, 34. When the basket 40 moves between the sprockets 31, 32, 33, 34, the tip of the horizontal arm 51 moves in the guide rails 60, 61, 62, 63. Vertical swing of the horizontal arm 51 is restricted by the guide rails 60, 61, 62 and 63. Therefore, the basket 40 is maintained in the vertical state.

When the basket 40 moves along the first and second sprockets 31, 32, 33, 34, the guide roller 52 engages with the notches 53, 54 of the guide discs 55, 56. As the basket 40 moves, the horizontal arm 51 rotates the guide disks 55 and 56. The horizontal arm 51 moves while being engaged with the guide discs 55 and 56. Therefore, the vertical state of the basket 40 is maintained. In this way, the basket 40 is constantly circulated while being kept in the vertical state.

The chain and the sprocket may be only the first chain 33 and the first sprockets 31 and 32. In this case, a circular guide rail having a U-shaped cross section may be installed in the place where the second chain is laid, and the traveling roller 65 may be moved in the guide rail to prevent the basket from tilting. .

[0017]

[Effect of device]

 Since the basket vertical maintenance device of the present invention has a structure in which the sprocket and the guide disc are displaced relative to each other by the same distance as the length of the horizontal arm, the space in the arrangement direction of the sprocket can be narrowed. In addition, since the upper center of the basket can be connected to the chain, the basket can be hung on the chain in a stable state.
