  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1> Overall Configuration The sorting method of the transport sorting apparatus according to the present embodiment is an example in the case where the article to be transported W transported in one row is branched to the left and right and repeatedly sorted into two rows.
FIG. 1 is a functional schematic diagram of the transport sorting apparatus according to the present invention, and FIG. 2 is a partial detailed view of the transport sorting apparatus of the present invention.
The transport sorting apparatus of the present embodiment includes a first conveyor 1 that transports the transported object W, a second conveyor 2 that automatically dispatches the transported object W at a predetermined timing, and a carry-out end of the first conveyor. A transfer member 3 interposed at a joint between the carry-in end of the second conveyor and the upper side of the first conveyor 1, the transfer member 3, and the second conveyor 2, the transported object W with a predetermined interval and a predetermined And at least a timing screw 4 that is transported at a speed of 5 mm. Each component will be described below.

<2> First conveyor 1
The first conveyor 1 is a conveyor that is used to carry the article to be conveyed W into the timing screw 4, and a conveyor belt 12 is provided to a pulley 11 of the conveyor, and the conveyor belt 12 is connected to the pulley 11. The motor is configured to rotate in response to the rotational driving force of the drive motor M and to rotate in a direction indicated by an arrow A at a constant speed.

<3> Second conveyor 2
The 2nd conveyor 2 is a general endless conveyor, Comprising: The guide member 23 which has the guide groove 231 which guides the to-be-conveyed object W in a branch distribution direction inside an endless conveyor (refer FIG. 3).
A number of parallel plates 21 are fitted into an extension chain (not shown) that conducts rotation with the drive chain wheel, and the parallel plates 21 slide along the longitudinal direction (left-right direction) of the parallel plates 21. A possible transport plate 22 is provided, and a transported object W is placed on the transport plate 22 so as to be distributed and transported.

  Further, a protruding portion 221 such as a pin or a bearing is provided at the lower portion of the conveying plate 22, and the protruding portion 221 engages or slides in the guide groove 231 of the guide member 23, so that the conveying plate 22 has a lateral direction. To move to.

  The guide grooves 231 of the guide member 23 are provided separately and independently by the number of rows to be distributed. Accordingly, the guide grooves 231 are close to each other before the transfer of the transported object W, and the transport plate 22 moves in the left-right direction as the guide grooves 231 gradually move away. Execute. In the present embodiment, the objects to be conveyed W are periodically distributed by switching the positions of the protruding portions 221 for every four conveying plates 22.

  In addition, it can respond to the change of the full length of the to-be-conveyed object W by arrange | positioning the conveyance board 22 which provided the protrusion part 221 in the same position continuously.

  Although the forward path of the second conveyor 2 has been described above, it is needless to say that the guide groove 231 is formed so that the transport plate 22 is restored to a position aligned in a row on the backward path of the second conveyor 2.

  The second conveyor 2 in this embodiment does not control the distribution direction of the conveyance plate 22 by a sensor or the like, but by specifying the order in which the conveyance plates 22 attached to the protrusions 221 at different positions are specified in advance. The distribution work is forcibly executed.

<4> Timing screw 4
The timing screw 4 is a member that can be controlled so as to align a plurality of objects to be conveyed W that are irregularly spaced apart or in close contact with each other at a predetermined interval and to carry them out at a predetermined speed. is there.

  The drive source of the timing screw 4 is obtained from a drive motor M that drives the second conveyor 2 using a known transmission mechanism 7, and the gear ratio of the transmission mechanism 7 and the initial positions of the timing screw and the conveying plate are determined. It adjusts beforehand and the carrying-out timing of the to-be-conveyed object W from the timing screw 4 and the distribution timing of the conveyance board 22 of the 2nd conveyor 2 are completely synchronized.

  In the timing screw 4 of the present embodiment, an inlet part 41 that meshes the articles to be conveyed W with thread grooves and separates them one by one, and each article to be conveyed W separated in the inlet part 41 at a predetermined interval. An intermediate portion 42 that increases the speed of the conveyed object W while spreading, and an outlet portion 43 that is formed so as to maintain the final pitch in the intermediate portion 42 and carries each conveyed object to the next process at a constant speed and at equal intervals. It is divided into three places for convenience.

  The outlet portion 43 is preferably configured to provide a plurality of the same pitch width.

The timing screw 4 is attached to a position across the upper portions of the first conveyor 1, the crossover member 3, and the second conveyor 2, and the outlet portion 43 is disposed at a position where it overlaps the conveyance path of the second conveyor 2.
In the present embodiment, the same timing screw 4 is provided at two locations on the upper side of the first conveyor 1, the crossover member 3 and the second conveyor 2, and the object to be conveyed W is gripped from the left and right side surfaces, thereby being more stable. We are trying to improve.

  In addition, the outlet 43 may be disposed not only at a position overlapping with the transport path of the second conveyor 2 but also at a position overlapping with the transition member 3. By making the conveyance speed of the article to be conveyed W on the transfer member 3 constant, the replacement between conveyors can be made more stable.

  The crossover member 3 may be any other member such as a crossover plate or a roller, and may be any member that can stably transport the object to be transported, and is not particularly limited.

  Next, the conveyance state of the article to be conveyed W when the sorting apparatus of the present invention is operated will be described.

<1> Conveyance on the first conveyor The conveyed object W continuously conveyed from the first conveyor 1 stops for a short time until it engages with the thread groove of the timing screw 4. Due to this stop time, the object to be conveyed W stays in close contact with the timing screw 4 and advances at a speed slower than the conveying speed of the first conveyor 1.

<2> Conveying on Timing Screw At the inlet 41, the object to be conveyed W is engaged with a screw groove and separated into one piece. In the intermediate part 42, the pitch (movement distance of the conveyed object in one rotation of the screw) is increased so that the moving speed of the conveyed object W and the conveying speed of the second conveyor 2 are made constant. Since the exit part 43 is formed so as to maintain the final pitch of the intermediate part 42, the moving speed of the article to be transported W is maintained at the same speed as the transport speed of the second conveyor 2.

<2> Replacing the Timing Screw with the Second Conveyor The timing screw 4 and the second conveyor 2 use the drive motor M which is the same drive source, and the gear ratio of the transmission mechanism 7, the timing screw 4 and the conveyance Since the initial position of the plate 22 is adjusted in advance, the carry-out timing of the conveyed object W from the timing screw 4 and the movement of the transfer plate 22 of the second conveyor 2 are completely synchronized with each other at a fixed timing. Thus, the article to be conveyed W is placed on the conveying plate 22.
Since the rotational speed of the timing screw 4 and the second conveyor 2 is in a proportional relationship, the synchronization between the timing screw 4 and the second conveyor 2 is not broken by the change in the rotational speed of the drive motor M, and is stable even at high speed operation. Can be realized.

  Moreover, the carry-in speed and the distribution timing can be easily changed only by changing the rotation ratio between the drive source and the timing screw and the distribution pitch width of the second conveyor, and the versatility is very high.
