An endless transport chain 25 is wound around the drive sprocket 23 and the driven sprocket 24.

  Here, as for the material of the transport chain 25, the place where the transport device 2 is disposed is in a clean room or a washing machine, so that a metal material that requires a lubricant such as grease is not suitable. And those made of UPE (High Density Polyethylene) having excellent wear resistance are more preferable.

Thus, the transport chain 25 is extended along the transport direction of the glass sheet W on the front side above the base 1.
A plurality of receivers 10, 10 to be described later are disposed on the outer peripheral portion of the transport chain 25 with a predetermined interval along the extending direction of the transport chain 25.

  By the way, the transport device 2 includes a drive motor 26 provided at the center of the top plate 1a, a plurality of housings 27, 27,... Disposed along the transport direction on the top surface of the top plate 1a, A connection mechanism 28 for connecting the drive motor 26 and the housing 27 is provided.

Thereby, the driving force by the driving motor 26 is transmitted in order to the shaft 28 a, the gear 28 b, the first gear 21 a, and the driving shaft 21, and the conveying chain 25 is rotationally driven via the driving sprocket 23.

Next, the inclination guide 3 will be described.
The inclined guide 3 is for maintaining the conveying posture of the sheet glass W when the sheet glass W is conveyed by the conveying device 2.
The inclined guide 3 includes a plurality of long shafts 31, 31... (FIG. 5 is a cross-sectional view, so that only one long shaft 31 is shown) and coaxially at one end of each long shaft 31. It is comprised by the gear 32 of the bevel gear fitted, and the some guide roller 33 * 33 fitted coaxially in the other end part of each elongate shaft 31, having a predetermined space | interval.

Each long shaft 31 is disposed with its end on the gear 32 side facing downward while the axial direction is orthogonal to the top plate 1a.
Further, the plurality of long shafts 31, 31... Are arranged in a straight line along the conveying direction of the plate glass W while being parallel to each other and having a predetermined interval.

  The plurality of long shafts 31, 31... Are rotatably supported by the support frame 34 fixed on the top plate 1a via the bearings 34a, 34a.

  The guide roller 33 is a disk-shaped member that is in direct contact with the glass sheet W when the conveying posture of the glass sheet W is maintained, and is formed of, for example, a thermoplastic resin having excellent chemical resistance. .

Specifically, as shown in FIG. 4, when the sheet glass W is conveyed by the conveying device 2, the sheet glass W is brought into contact with the outer peripheral surface of the guide roller 33 on the back side plane, and the conveyance posture is maintained. .
At this time, the conveying posture of the glass sheet W is slightly inclined to the back side from the lower side to the upper side.
In other words, the inclination angle of the long shafts 31, 31... With respect to the vertical direction and the guide so that the inclination angle of the plate glass W with respect to the vertical plane V becomes a slight value α (0 <α << 90) [°]. The radial dimension of the roller 33 is set.

  In this way, the long shaft 31, 31... And the guide roller 33 cause the sheet glass W to be conveyed in a substantially vertical state with a slight inclination, so that, for example, an unexpected shock or vibration may be generated from the outside. Even if it is a case where it is added, the plate glass W in the middle of conveyance becomes difficult to drop off from the receptacle 10.

In addition, about the number of guide rollers 33 * 33 provided in one long shaft 31, it is not limited to this embodiment, For example, based on the size of the plate glass W, it is good also as one piece, and three pieces. It is good also as above.
In addition, the arrangement position of the guide rollers 33 and 33 with respect to the long shaft 31 is not limited to the present embodiment, for example, based on the size of the plate glass W, It may be evenly arranged over the entire length.

As shown in FIG. 3, the housings 27, 27,... Described above are disposed below the plurality of long shafts 31, 31,.
Here, as shown in FIG. 5, a relay shaft 29 is provided through the upper portion of the housing 27.

  The relay shaft 29 is disposed in parallel with the drive shaft 21 so that both end portions protrude to the outside of the housing 27. The relay shaft 29 is rotatably supported by bearings 27 b and 27 b provided inside the housing 27.

A third gear 29 a made of a spur gear is coaxially fitted to the rear side end of the relay shaft 29, and the third gear 29 a is engaged with the second gear 21 b of the drive shaft 21. The
On the other hand, a fourth gear 29b made of a bevel gear is coaxially fitted to the front end of the relay shaft 29, and the fourth gear 29b meshes with the gear 32 of the long shaft 31. .

Thus, the long shaft 31 is connected to the drive motor 26 via the relay shaft 29, the drive shaft 21, and the connection mechanism portion 28 that are pivotally supported by each housing 27.
Thereby, the driving force by the drive motor 26 (see FIG. 3) is generated by the shaft 28a, the gear 28b, the first gear 21a, the drive shaft 21, the second gear 21b, the third gear 29a, the relay shaft 29, and the fourth gear 29b. The gears 32 and the long shaft 31 are transmitted in this order, and the guide rollers 33 and 33 are rotationally driven.

By having the above configuration, the driving force of the drive motor 26 is simultaneously transmitted to the conveying chain 25 of the conveying device 2 and the long shaft 31 of the inclined guide 3.
As a result, the plurality of long shafts 31, 31... Are rotated in synchronization with the rotational drive of the transport chain 25, and the guide rollers 33, 33. Will be rotated.

In the present embodiment, only the housing 27 located on the most downstream side in the transport direction, the drive sprocket 23 is fitted on the front side end of the drive shaft 21 that is pivotally supported by the housing 27. Further, only the housing 27 located on the most upstream side in the transport direction is supported by a driven shaft 22 having substantially the same shape as the drive shaft 21, and a driven sprocket 24 is provided at the front end of the driven shaft 22. It is installed.
In the plurality of housings 27, 27,... Excluding the most upstream side and the most downstream side in the conveying direction, sprockets and the like are provided at the front side end portions of the respective drive shafts 21, 21. There is no.

  However, the configuration of the housing 27 and the coupling mechanism portion 28 in the present embodiment is not particularly limited, and the drive motor is configured so that each long shaft 31 rotates in synchronization with the rotation drive of the transport chain 25. Any configuration is possible as long as it can transmit the driving force of 26.

3, guide rails 30 are arranged on the front side of the plurality of housings 27, 27.
The guide rail 30 is a member for preventing the conveyance chain 25 from being bent and laterally displaced, and is arranged between the drive sprocket 23 and the driven sprocket 24 so as to extend in the conveyance direction. .

  Then, as shown in FIG. 1A, the conveyance chain 25 that has passed through the driven sprocket 24 slides along the upper end of the guide rail 30 to the drive sprocket 23, thereby bending the conveyance chain 25. And lateral deviation are effectively regulated.

  As for the material of the guide rail 30, since the place where the conveying device 2 is disposed is in the washing machine, it may be possible to adopt the one made of SUS, but as described above, UPE (high density polyethylene). ) Made of UPE, which is the same kind of material, is more preferable in consideration of preventing wear of the carry chain 25.

[Receiver 10]
Next, the structure of the receptacle 10 which embodies this invention is demonstrated using FIG.1, FIG.6 and FIG.7.
In the following description, for the sake of convenience, the vertical direction in FIGS. 1, 6 and 7 is described as the vertical direction of the receiver 10, the brush cleaning device 102, and the conventional receiver 110, respectively.
Moreover, in FIG.1 (b), the direction of the arrow A is described and prescribed | regulated as the conveyance direction of the plate glass W. FIG.
Further, in FIGS. 1A, 6, and 7, the right side and the left side when viewed from the conveying direction of the glass sheet W are respectively defined as the front side and the back side of the charging device 101 (or the brush cleaning device 102). Describe.

The receiving device 10 in this embodiment is a plate glass vertical transfer receiving device that conveys a plate glass W erected substantially vertically, and is provided in the conveying device 2 (see FIG. 3) and conveys the plate glass. It is for holding W.
The receptacle 10 is configured by an “L” -shaped member made of, for example, a thermoplastic resin excellent in chemical resistance or a synthetic rubber such as EPDM.
In addition, about the member consisting of a resin raw material, the thing of hardness (type A durometer hardness) 60-80 grade is more preferable.

  Specifically, as shown in FIG. 1 (a), the receiving device 10 includes a receiving surface 10a extending in a horizontal direction from the back side to the front side of the charging device 101, and a back surface of the receiving surface 10a. A guide surface 10b that stands up from the side end and is parallel to the conveying direction of the glass sheet W is formed.

And in the outer peripheral part of the conveyance chain 25 with which the conveying apparatus 2 is equipped, several receptacles 10 * 10 ... are attached to the said conveyance chain 25 for every predetermined number of links via bracket 25a * 25a .... Assembled.
As a result, the receiving surface 10a of the receiving device 10 is in a state in which the plate glass W is conveyed (in the state where the receiving device 10 is positioned on the conveying chain 25 between the drive sprocket 23 and the driven sprocket 24 and in the upper region). It arrange | positions in parallel with the top plate 1a of the base | substrate 1. FIG.

  By using the receiving device 10 having such a shape as a receiving device for the conveying device 2, the loading operation of the plate glass W to the charging device 101 (more specifically, the conveying device 2) has made a leap forward compared to the prior art. Easily.

That is, as shown in FIG. 7, a conventional receiver (hereinafter referred to as “conventional receiver”) 110 is configured by a rectangular parallelepiped member having a “V” -shaped groove 110 </ b> A at the center of the upper surface. It was.
Specifically, the conventional receiver 110 includes a receiving surface 110a that extends in the horizontal direction along the conveying direction of the glass sheet W, and a first guide surface 110b that stands from the rear side end of the receiving surface 110a. The groove portion 110 </ b> A formed by the second guide surface 110 c erected from the front side end portion of the receiving surface 110 a was formed.

  When a plurality of conventional receivers 110, 110... Having such a shape are assembled to the transport chain 25 of the transport device 2 for each predetermined number of links, a sheet glass is formed from the front side of the charging device 101. If W is to be thrown into the throwing device 101 (more specifically, the transporting device 2), the plate glass W is temporarily placed on the second guide surface in order to avoid interference between the lower end of the plate glass W and the second guide surface 110c. After lifting up above the upper end of 110c, it is necessary to place it on the receiving surface 110a positioned below the upper end of the second guide surface 110c, and the loading operation of the plate glass W to the loading device 101 is complicated. It was.

  On the other hand, when a plurality of receivers 10,... (See FIG. 1) as shown in the present embodiment are assembled to the transport chain 25 of the transport device 2, the front surface of the input device 101. Since there is no portion in the receiving device 10 that interferes with the lower end of the plate glass W when the plate glass W is put into the charging device 101 while the plate surface is directed in the extending direction of the receiving surface 10a from the side, the plate glass It is possible to move W in the substantially horizontal direction without moving it up and down and place it on the receiving surface 10a, and the loading operation of the plate glass W to the loading apparatus 101 becomes easy.

As described above, the transport device 2 is provided not only in the input device 101 but also in other brush cleaning devices 102, rinse devices 103, drying devices 104, and take-out devices 105 that constitute the cleaning system 100.
In the device group 101, 102,... 105, in the loading device 101, the brush cleaning device 102, and the take-out device 105, the receiving device 10 is used as a receiving device for the conveying device 2, and other rinses are performed. In the apparatus 103 and the drying apparatus 104, the conventional receiver 110 is used as the receiver of the transport apparatus 2.
This is because the rinsing device 103 and the drying device 104 do not need to perform the operation of putting the plate glass W into the conveying device 2 or perform brush cleaning, and the effect of using the receiving device 10 as the receiving device of the conveying device 2 is small. Instead, in the rinsing step and the drying step, it is necessary to firmly hold the plate glass W being conveyed, and the effect of using the conventional type receiving device 110 as the receiving device of the conveying device 2 is great.

  Further, in the take-out device 105, the receiving device 10 is used as a support for the transport device 2 in the same manner as the above-described feeding device 101 when the plate glass W is taken out to the front side of the take-out device 105. This is because the plate 10 can be moved from the receiving surface 10a by moving in the substantially horizontal direction, and the take-out work from the take-out device 105 is facilitated.

  Further, in the brush cleaning device 102, the receiving device 10 is used as the receiving device of the conveying device 2 because of the cleaning generated at the lower end of the plate surface of the plate glass W due to the second guide surface 110c of the conventional receiving device 110. This is to prevent unevenness.

Specifically, for example, when the conventional receiver 110 is used as the receiver of the transport device 2 in the brush cleaning device 102, the bristles of the cleaning brush 121 (see FIG. 6) It is blocked by the two guide surfaces 110c and does not sufficiently reach the lower end of the flat surface of the plate glass W, resulting in uneven cleaning.
On the other hand, as shown in FIG. 6, in the brush cleaning device 102 according to the present embodiment, since the receiving device 10 is used as the receiving device of the conveying device 2, the hair tip of the cleaning brush 121 is made of the plate glass W. It reaches the lower end of the flat surface sufficiently, and cleaning unevenness does not occur.

  By the way, as shown to Fig.1 (a), the guide surface 10b of the holder 10 is formed in the taper shape which inclines to a back side gradually as it goes upwards.

  Thus, by making the shape of the guide surface 10b into a tapered shape, in the conveying device 2 including the receiving device 10, it may occur when the plate glass W is transferred to the conveying device 2 from the upstream side of the conveying device 2. Scratches and dirt due to rubbing between the lower end of the plate glass W and the holder 10 can be effectively prevented.

  Specifically, on the upstream side of the transport device 2, for example, when the position of the plate glass W that is about to transfer to the transport device 2 is slightly shifted to the back side (the plate glass W1 in FIG. 1A). The lower end of the glass sheet W is in line contact with the plane of the guide surface 10b via the ridgeline of the lower end.

  Then, as the glass sheet W is conveyed to the conveying device 2 side, it gradually slides down the guide surface 10b via the ridgeline, and a predetermined placement position on the receiving surface 10a (the glass sheet W2 in FIG. 1 (a)). To the position indicated by

  Therefore, for example, if the guide surface 10b has a vertical shape, when the plate glass W is moved to a predetermined placement position on the receiving surface 10a, the lower end of the plate glass W is brought into surface contact with the guide surface 10b, and the receiving tool. However, in the case of the receiving device 10 in this embodiment, the lower end of the plate glass W is in line contact with the guide surface 10b. The contamination can be effectively prevented.

  Moreover, as shown in FIG.1 (b), in the predetermined mounting area | region (area | region shown by the area | region Z of Fig.1 (a)) on the receiving surface 10a of the holder 10, conveyance of the plateglass W is carried out. R chamfered portions 10c and 10c are formed at the upstream end and the downstream end in the direction.

  As described above, the R chamfered portions 10c and 10c are formed at the upstream end portion and the downstream end portion of the receiving surface 10a, respectively. It is possible to effectively prevent the occurrence of vibrations in the vertical direction of the glass sheet W that may occur when the glass sheet W is transferred from the upstream side.

Specifically, the transfer chain 25 is moved following the rotational movement of the driven sprocket 24 in the transfer section on the upstream side of the transfer device 2.
Thereby, the plurality of receivers 10, 10... Arranged on the transport chain 25 are sequentially moved while drawing a trajectory of an arc from the bottom to the top, and after reaching the transport level of the plate glass W, It is moved in the horizontal direction (more specifically, the conveying direction of the plate glass W).

Here, for example, when the above-described R chamfered portions 10c and 10c are not formed on the receiving surface 10a of the receiving device 10, the position immediately before the receiving device 10 is moved in the horizontal direction (see FIG. 1B). The lower end of the glass sheet W is downstream of the receiving surface 10a until it reaches the position moved in the horizontal direction (the position indicated by the receiving tool 10B in FIG. 1B) from the position indicated by the receiving tool 10A. It is pushed up obliquely upward by the side end portion, and is positioned higher than the receiving surface 10a of the receiving tool 10 in a position moved in the horizontal direction, and vertical vibrations are generated in the plate glass W. It will be.
On the other hand, if the R chamfered portions 10c and 10c are respectively formed at the upstream end portion and the downstream end portion of the receiving surface 10a as in the case of the receiving device 10 of the present embodiment, it moves in the horizontal direction. Since the receiving surface 10a of the receiving device 10 at the position immediately before being placed is not positioned higher than the receiving surface 10a of the receiving device 10 at the position moved in the horizontal direction, Generation of vibration can be effectively prevented.

  As described above, the receiving device 10 according to the present embodiment is a plate glass vertical transfer receiving device on which the plate glass W is placed when the plate glass W standing upright is conveyed. A guide surface that extends in the direction and serves as a mounting surface for the plate glass W, and a guide that stands up from an end of one side of the receiving surface 10a in the extending direction (in the present embodiment, the back surface side of the charging device 101). The sheet glass W to be conveyed is directed to the other side of the extending direction (in the present embodiment, the front surface of the charging device 101) with the plate surface facing the extending direction of the receiving surface 10a. It is configured to be placed on the receiving surface 10a from the side).

According to the receiving device 10 having such a configuration, it is possible to place the glass sheet W on the receiving surface 10a by moving the receiving device 101 in a substantially horizontal direction from the front side of the charging device 101. The plate glass W can be detached from the receiving surface 10a by moving in the substantially horizontal direction to the front side, and the loading and unloading operations of the plate glass W can be facilitated.
Further, according to the receiver 10 having such a configuration, the brush tip of the cleaning brush 121 sufficiently reaches the lower end of the flat surface of the plate glass W in the brush cleaning device 102, so that the occurrence of cleaning unevenness is ensured. Can be prevented.

  Further, in the receiving tool 10, the guide surface 10b is formed in a tapered shape that gradually inclines toward one side in the extending direction of the receiving surface 10a as it goes upward.

  According to the receiver 10 having such a configuration, the lower end of the plate glass W that can be generated when the plate glass W is transferred from the upstream side of the transfer device 2 in the transfer device 2 including the receiver 10, and the receiver Generation of scratches and dirt due to rubbing with the tool 10 can be effectively prevented.

  Further, as an example of the receiving device 10, the receiving device 10 is configured by EPDM.

  Thus, since the receptacle 10 is formed of EPDM having excellent chemical resistance, it can be used sufficiently even in a cleaning system using a strong alkaline detergent.

  In addition, the transport device 2 in the present embodiment is configured as a device including the receiver 10 shown above, and the cleaning system 100 in the present embodiment includes a charging device 101 and a brush cleaning device including the transport device 2. 102 and the take-out device 105.

  Therefore, in the transport device 2 and the cleaning system 100 in the present embodiment, it is possible to facilitate the loading and unloading work of the sheet glass W and to prevent the occurrence of uneven cleaning.
