Description

  The present invention relates to a transport device for a plate-like body such as plate glass and a transport method for the plate-like body.

  Conventionally, when manufacturing a plate-like body such as a plate glass, the direction of the plate-like body flowing on the conveyance path may be changed by a predetermined angle (for example, 90 °) (see, for example, Patent Document 1).

International Publication No. 2012/039252

  FIG. 9 shows, as a conventional example, a transport apparatus 110 that transports the plate-like body W carried from the previous process to the subsequent process while changing the direction of the plate-like body W. In the same example, the carry-in conveyor 111 of the transfer device 110 has a set of plate-like bodies W cut out in a product size (three in the same example) from one original plate as a set (S1) in order to improve productivity. It is carried in from the previous process. The plate-like bodies W carried into the carry-in conveyor 111 as a set of three sheets (S1) are transferred to the carry-out conveyor 112 one by one as shown in FIGS. At the time of this transfer, the orientation of the plate-like body W with respect to the transport direction X is changed by 90 °. By changing the orientation of each plate-like body W in this way, for example, an unprocessed end face can be directed to the side, and the end face can be easily processed in a later process (not shown). Finally, when one set (S1) of the plate-like bodies W is transferred to the carry-out conveyor 112 and the carry-in conveyor 111 is empty, as shown in FIG. 1 set (S2) can be carried in from the previous process.

  In such a transfer device 110, while one set (S1) of the plate-like bodies W is being transferred from the carry-in conveyor 111 to the carry-out conveyor 112, one set (S2) of the next plate-like bodies W is transferred. Since it cannot carry in to the carrying-in conveyor 111, the space | interval of 1 set (S1) of the front plate-shaped body W carried out from the carrying-out conveyor 112 and the next 1 set (S2) becomes wide, and productivity is increased. It is disadvantageous in terms of improvement.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a plate-shaped member conveying apparatus and a plate-shaped member conveying method capable of improving productivity. It is in.

  A plate-shaped body conveyance device that solves the above-described problems is a plate-shaped body conveyance device that transfers a plate-shaped body from an upstream carry-in conveyor to a downstream carry-out conveyor, and is arranged in parallel to the side of the carry-in conveyor. A conveyor that is arranged to run and conveys the plate-like body transferred from the carry-in conveyor, a loading-side transfer unit that transfers the plate-like body from the carry-in conveyor to the conveyer, and the conveyance A carry-out side transfer unit for transferring the plate-like body from the conveyor to the carry-out conveyor, and the carry-in side transfer unit or the carry-out side transfer unit changes the orientation of the plate-like body with respect to the conveyance direction. Then, the plate-like body is transferred.

  According to this configuration, when a plurality of plate-like bodies are carried into the carry-in conveyor for each set from the previous process, the conveyer in which one set of plate-like bodies carried into the carry-in conveyor is arranged on the side of the carry-in conveyor. It is possible to transfer it quickly. And while transferring the plate-like body from the conveyor to the carry-out conveyor, one set of the next plate-like bodies can be carried into the empty carry-in conveyor, so the front plate carried out from the carry-out conveyor It is possible to reduce the interval between one set of the objects and the next set, and as a result, it is possible to improve productivity. Further, the loading-side transfer unit that transfers the plate-like body from the carry-in conveyor to the transfer conveyor, or the unloading-side transfer unit that transfers the plate-like body from the transfer conveyor to the carry-out conveyor, The direction can be changed. In this way, it is possible to improve productivity in a transporting apparatus that transports a plurality of plate-like bodies to each set and transports them to a subsequent process while changing the orientation of the plate-like bodies with respect to the transporting direction. Become.

In the plate-like body transfer device, it is preferable that a plurality of the transfer conveyors are provided.

And the other is transferred to the conveyor on the other side of the carry-in conveyor.

  According to this configuration, in the stage of transferring (rotating and transferring) the plate-like body group on the transfer conveyor to the transfer conveyors on both sides of the carry-in conveyor while changing the direction by the transfer unit, it is adjacent to the transfer direction. One of the plate-like bodies to be fitted is transferred to the conveyor on one side of the carry-in conveyor, and the other is transferred to the conveyor on the other side of the carry-in conveyor. Thereby, even when the interval between the plurality of plate-like bodies carried into the carry-in conveyor is narrow, each plate-like body can be simultaneously transferred to each conveyor without causing the adjacent plate-like bodies to interfere with each other. It becomes possible. In other words, in order to prevent interference between the plate-like bodies when rotating and transferring from the carry-in conveyor to the carry conveyor, a treatment such as increasing the interval between the plate-like bodies carried into the carry-in conveyor becomes unnecessary. The length of the carry-in conveyor can be reduced, and consequently the line length of the entire transfer device can be reduced.

Alternatively, in the second transfer step, the orientation of the plate-like body with respect to the transport direction is changed.

  According to this method, when a plurality of plate-like bodies are carried into the carry-in conveyor for each set from the previous process, a conveyer in which one set of plate-like bodies carried into the carry-in conveyor is arranged on the side of the carry-in conveyor. It is possible to transfer it quickly. And while transferring the plate-like body from the conveyor to the carry-out conveyor, one set of the next plate-like bodies can be carried into the empty carry-in conveyor, so the front plate carried out from the carry-out conveyor It is possible to reduce the interval between one set of the objects and the next set, and as a result, it is possible to improve productivity. Further, in the first transfer process of transferring the plate-like body from the carry-in conveyor to the transfer conveyor or the second transfer process of transferring the plate-like body from the transfer conveyor to the carry-out conveyor, The direction can be changed. In this way, it is possible to improve productivity in a transport method in which a plurality of plate-shaped bodies are carried into each set and transported to a subsequent process while changing the orientation of the plate-shaped bodies with respect to the transport direction. Become.

  In the transport method for the plate-like body, in the carrying-in step, a plurality of the plate-like bodies are carried into the carry-in conveyor, and in the first transfer step, the plate-like body on the carry-in conveyor is paired with the transport. It is preferable to transfer each plate to a conveyor, and in the second transfer step, the plate-like body is alternately transferred from the pair of transfer conveyors to the carry-out conveyor.

  According to this method, the plate-like body is alternately transferred from the pair of transfer conveyors to the carry-out conveyor in the second transfer step. Therefore, the unit time of the plate-like body to be transferred to the carry-out conveyor without shortening the transfer interval from one transfer conveyor to the carry-out conveyor and the transfer interval from the other transfer conveyor to the carry-out conveyor. It is possible to increase the number of hits (that is, the number of plate-like bodies to be carried out from the carry-out conveyor to the subsequent process), and it is possible to improve productivity with a mechanically reasonable configuration. .

Since the transfer start position is empty, the plate-like body W4 can be conveyed to the transfer start position. Then, as shown in FIG. 7, when the plate-like body W4 is conveyed to the transfer start position, the transfer locations on both the first and second transfer conveyors 12a and 12b are empty, and the first and second The transfer units 14a and 14b rotate and transfer the next plate body group WG2 (plate bodies W1 to W4) from the carry-in conveyor 11 to the first and second transfer conveyors 12a and 12b in the above-described manner.

  Next, as shown in FIG. 8, the 3rd transfer part 15 transfers the plate-shaped body W4 from the 2nd conveyance conveyor 12b to the carry-out conveyor 13 along the transfer direction Y by the movable part 19b. Thereafter, the carry-out conveyor 13 carries out the plate-like body W4 transferred from the second transfer conveyor 12b to a subsequent process. At this time, the first and second transport conveyors 12a and 12b are configured such that the plate-like bodies W1 and W2 placed on the downstream side of the respective conveyors 12a and 12b are the third transfer unit 15 (rail unit 18). The plate-like bodies W1 to W4 are transported in the transport direction X until the transfer start position set below is reached. Simultaneously with the conveyance of the plate-like bodies W1 to W4 by the first and second conveyance conveyors 12a and 12b, the carry-in conveyor 11 carries in the next plate-like body group WG3 from the previous step.

  Thereafter, the transport apparatus 10 repeats the above operation, and sequentially carries out the plate-like body group WG (plate-like bodies W1 to W4) carried in from the previous process to the subsequent process. In the present embodiment, the intervals between the plate-like bodies W sequentially carried out from the carry-out conveyor 13 to the subsequent process are equal.

Next, characteristic effects of the present embodiment will be described.
(1) The transport apparatus 10 includes first and second transport conveyors 12 a and 12 b that are arranged so as to run sideways of the carry-in conveyor 11 and that transport the plate-like body W transferred from the carry-in conveyor 11. Further, the transfer device 10 includes first and second transfer units 14a and 14b (transfer-side transfer units) that transfer the plate-like body W from the transfer conveyor 11 to the first and second transfer conveyors 12a and 12b, respectively. And a third transfer unit 15 (transfer-side transfer unit) that transfers the plate-like body W from the first and second transfer conveyors 12a and 12b to the transfer conveyor 13. And the 1st and 2nd transfer parts 14a and 14b which comprise a carrying-in side transfer part transfer this plate-shaped body W, changing the direction of the plate-shaped body W with respect to the conveyance direction X. As shown in FIG.

  According to this configuration, when a plurality of plate bodies W are carried into the carry-in conveyor 11 for each set (plate-like group WG) from the previous process, the plate-like group WG carried into the carry-in conveyor 11 is loaded. It becomes possible to quickly transfer to the first and second conveyors 12a and 12b arranged on the side of the conveyor 11. And since the next plate-shaped body group WG can be carried in to the empty carrying-in conveyor 11, while transferring the plate-shaped body W from the 1st and 2nd conveyance conveyor 12a, 12b to the carrying-out conveyor 13. The interval between the front plate group WG carried out from the carry-out conveyor 13 and the next plate group WG can be reduced, and as a result, the productivity can be improved. Moreover, the direction of the plate-shaped body W can be changed by the 1st and 2nd transfer parts 14a and 14b which transfer the plate-shaped body W from the carrying-in conveyor 11 to the 1st and 2nd conveyance conveyors 12a and 12b. As described above, productivity can be improved in the transport apparatus 10 that carries a plurality of plate-like bodies W in one set and transports them to a subsequent process while changing the orientation of the plate-like bodies W in the transport direction. It becomes possible.

  (2) The plate-like body W is transferred from the carry-in conveyor 11 to the first and second transport conveyors 12a and 12b, respectively, and the plate-like body W transferred to the first and second transport conveyors 12a and 12b is The first and second conveyors 12a and 12b are alternately transferred to the carry-out conveyor 13. For this reason, even if it does not shorten each of the transfer interval from the 1st conveyance conveyor 12a to the unloading conveyor 13, and the transfer interval from the 2nd conveyance conveyor 12b to the unloading conveyor 13, the board transferred to the unloading conveyor 13 It is possible to increase the number of sheets W per unit time (that is, the number of sheets W per unit time to be carried out from the carry-out conveyor 13 to the subsequent process), and it is possible to increase the productivity with a mechanically reasonable configuration. It is possible to improve.

  (3) Since the first and second conveyors 12a and 12b are arranged on both sides of the carry-in conveyor 11, the transfer distances from the carry-in conveyor 11 to the first and second carry conveyors 12a and 12b are kept short. It becomes possible. As a result, it is possible to reduce the time required to transfer the plate-like body W from the carry-in conveyor 11 to the first and second transport conveyors 12a and 12b.

  (4) Plates adjacent to each other in the transport direction X when the plate-like body group WG on the carry-in conveyor 11 is transferred to the first and second transfer conveyors 12a and 12b by the first and second transfer units 14a and 14b. One of the shaped bodies W is rotationally transferred to the first transfer conveyor 12a and the other is transferred to the second transfer conveyor 12b.

  Thereby, when each plate-like body W (plate-like bodies W1-W4) is rotationally transferred to the first and second transport conveyors 12a, 12b by the synchronous operation of the first and second transfer portions 14a, 14b, It can be set as the structure which adjacent plate-shaped bodies W do not interfere easily. Moreover, by this, in order to prevent interference between the plate-like bodies W at the time of rotational transfer from the carry-in conveyor 11 to the first and second transfer conveyors 12a and 12b, each plate-like body W carried into the carry-in conveyor 11 is prevented. A treatment such as increasing the interval is not necessary. As a result, the length of the carry-in conveyor 11 in the transport direction X can be suppressed, and consequently the line length of the entire transport device 10 can be suppressed.

In addition, you may change the said embodiment as follows.
In the above-described embodiment, the first and second transfer units 14a and 14b configuring the carry-in transfer unit are configured to transfer the plate-like body 90 by 90 °. That is, the orientation of the plate-like body W is changed by 90 ° in the first transfer process in which the plate-like body W is transferred from the carry-in conveyor 11 to the first and second transport conveyors 12a and 12b. However, the present invention is not particularly limited to this, and the third transfer unit 15 constituting the carry-out side transfer unit may transfer the plate-like body W by 90 °. That is, the orientation of the plate-like body W may be changed by 90 ° in the second transfer process in which the plate-like body W is transferred from the first and second transport conveyors 12a, 12b to the carry-out conveyor 13. In this case, it is desirable that the holding portions of the movable portions 19a and 19b of the third transfer portion 15 be configured to be rotationally driven around an axis along the vertical direction. Moreover, the change angle of the orientation of the plate-like body W is not limited to 90 °, and may be an angle other than 90 ° depending on the configuration.

  In the above embodiment, the four plate-like bodies W from the previous process are loaded into the carry-in conveyor 11 as one set (plate-like body group WG), but the plate-like bodies W carried into the carry-in conveyor 11 are used. The number of sheets in one set may be changed as long as it is two or more.

  For example, when one set of the plate-like bodies W is three, one of the three plate-like bodies W is used as the first transport conveyor 12a, and the other one is used as the second transport conveyor 12b. And you may comprise so that the remaining 1 sheet may be left in the carrying-in conveyor 11, or you may transfer to a 3rd conveyance conveyor. And you may comprise so that the plate-shaped body W may be transferred to the unloading conveyor 13 from the 1st conveying conveyor 12a, the 2nd conveying conveyor 12b, and the carrying-in conveyor 11 (or the said 3rd conveying conveyor), respectively.

  In the above embodiment, the first and second transport conveyors 12a and 12b are arranged in parallel on both sides of the carry-in conveyor 11. However, for example, the second transport conveyor 12b is omitted and only the first transport conveyor 12a is parallel. An arrangement may be adopted.
