The bottle feeding conveyor unit 1 includes a conveyor 11 driven by a motor 12 and a bottle guide 3 that divides the conveyor 11 into a plurality of lanes (two lanes in FIG. 3). The bottle guide 3 is a bottle feeding conveyor unit. 1 is deflected downstream in the direction of the bottle-making conveyor section 2. The bottle arranging conveyor section 2 comprises a conveyor 21 driven by a motor 22 and a bottle guide 3 dividing the conveyor 21 into a plurality of lanes. It is connected to Guide 3. A stopper 23 is provided at a downstream end of the bottle arranging conveyor section 2, and a portion of a length L where a predetermined number of bottles 5 are arranged upstream from the stopper 23 is a bottle gripping section 2a. A bottle counter 4 is provided upstream of the bottle grabber 2a, and counts the number of bottles 5 passing therethrough for each lane.
[0003]
Next, the operation of the bottle arranging conveyor device will be described. When the operation is started, bottles 5 densely arranged in a plurality of rows (two rows in FIG. 3) by a sorting device (not shown) located upstream are supplied to the bottle feeding conveyor section 1 and The bottle is conveyed along each lane by the conveyer 11 and transferred to the bottle conveyer unit 2 by the deflection unit of the bottle guide 3.
Next, the bottles 5 are conveyed by the conveyor 21 of the bottle arranging conveyor section 2 and are stopped by contacting the stopper 23 at the end. The bottles 5 whose movement has been stopped by the stopper 23 are stopped while sliding the bottom surface on the moving conveyor 21. Further, the succeeding bottles 5 are sequentially stopped by contacting the bottles 5 stopped downstream. Further, the bottles 5 entering the bottle grabber 2a are counted by the bottle counter 4 at the entrance for each lane. When all the lanes reach a predetermined number, a signal is output from the bottle counter 4 and the motors 12 and 22 are activated. Stop. Next, the gripper (see 7 in FIG. 2) descends, grasps and lifts the head of the bottles 5 in the bottle grasping section 2a, moves to another place, and performs a predetermined operation such as packing. When the gripper is raised, the drive motors 12 and 22 are started again, and the same operation as described above is repeated.
[0004]
[Problems to be solved by the invention]
In FIG. 3, if a broken bottle, a falling bottle, or a bottle jam occurs in any one of a plurality of lanes on the upstream side of the bottle gripping unit 2a and the conveyance of the bottles 5 in the lane is delayed, the bottle counter 4 sets the same lane. The conveyor will continue to move until the predetermined number is counted. Therefore, in the normal lane, the bottle grasping portion 2a is filled with a predetermined number of bottles 5 and the bottles 5 are connected in a press-down state even further upstream, so that each upstream bottle 5 to be advanced by the conveyor is moved. Is applied as a pressing force to the downstream bottles 5 to deform the downstream bottles 5 or the bottle guides 3. In particular, the bottles 5 in the bottle gripping portion 2a located at the most downstream are deformed by receiving a strong pressing force, so that the bottle gripping operation by the gripper becomes impossible, or the bottle guide 3 is deformed in the middle of the lane and the bottle guide 3 is deformed. There was a problem that hindered the running of bottles 5 in the lane.
According to the present invention, when the conveyor of the bottle feeding conveyor section is stopped, the pressing force applied to the bottles by the bottle gripping section of the bottle regulating conveyor section is kept to a minimum, so that the bottle gripping operation becomes impossible or the bottle guide is deformed. An object of the present invention is to provide a bottle-conveying apparatus in which the running of bottles is not hindered, and to solve the above-mentioned conventional problems.
[0005]
[Means for Solving the Problems]
Therefore, according to the present invention, a bottle feeding conveyor section having a plurality of lanes formed by a bottle guide and a bottle regulating conveyor section are arranged in series via a passing plate, and the bottle feeding conveyor section is driven by a motor for each lane in the bottle feeding conveyor section. In the same bottle conveyor section, a conveyor common to all lanes driven by one motor, a stopper for stopping bottles at the downstream end, and a predetermined number of bottles from the stopper are provided. A bottle counter is provided at an upstream position of the bottle gripping section where the conveyor speed of the bottle arranging conveyor section is higher than the conveyor speed of the bottle feeding conveyor section. Stop the conveyor in the lane concerned, count the predetermined number in all lanes, stop the conveyor in the bottle arranging conveyor section, and start all conveyors again when bottles in the bottle gripping section are taken out. Become things, it is an unit for which a problem solution.
[0006]
[Action]
When the bottle counter counts a predetermined number in each lane, the drive of the conveyer of the corresponding lane of the bottle supply conveyor unit is stopped regardless of the state of the other lanes. It is not necessary to receive excessive pressing force due to the kind.
Since bottles are transported at intervals in the bottle-shaping conveyor, the number of bottles remaining on the bottle-shaping conveyor upstream of the bottle gripper after the conveyor in the bottle-feeding conveyor stops is small. Also, since the interval is large, a large pressing force does not occur. In the lane in which the transport delay occurs, the bottle counter continues to operate until the predetermined number is counted. This is a normal operation, and if there is a cause of the transport delay, it is necessary to remove the cause.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the embodiments of the drawings. FIG. 1 is a plan view of a bottle conveyor device showing an embodiment of the present invention, and FIG. 2 is a front view of FIG.
The apparatus shown in FIGS. 1 and 2 comprises a bottle feeding conveyor section 101 and a bottle arranging conveyor section 102, both of which are arranged in series, and a connecting plate 106 is provided at the connection section. The bottle feeding conveyor unit 101 is partitioned by a bottle guide 103 into a plurality of lanes (two lanes in FIG. 1) having a width slightly larger than the width of the bottles 5, and each lane is driven by a motor 112a, 112b, 112c, respectively. Conveyors 111a, 111b and 111c are provided (two-dot chain lines in the figure show one embodiment of motor arrangement in the case of three lanes). The bottle arranging conveyor section 102 is divided into the same number of lanes by the bottle guide 103 similarly to the bottle supplying conveyor section 101, and the lane driven by the motor 112 has a common conveyor 121. The transport speed of the conveyor 121 is set slightly higher than the transport speed of the conveyors 111a, 111b, 111c. A stopper 123 is provided at a downstream end of the lane, and a portion of a length L where a predetermined number of bottles 5 are arranged upstream from the stopper 123 is a bottle grip portion 102a. The bottle grasping portion 102a is a place where the gripper 7 descends from above and grasps and lifts the bottles 5. Further, a bottle counter 4 is provided on the upstream side of the bottle grasping unit 102a, so that the number of bottles 5 passing therethrough can be counted for each lane.
[0008]
Next, the operation of the embodiment configured as described above will be described. The bottles 5 are supplied to each lane of the bottle supply conveyor unit 101 from the upstream by a bottle guide, and the conveyors 111a, 111a, At 111b and 111c, the paper is conveyed to the bottle conveyor 102. At the place where the bottles are transferred to the bottle-shaping conveyor section 102, they pass over the stationary passing plate 106, but are pushed by the succeeding bottles 5, so that they are transferred to the bottle-shaping conveyor section 102 without stopping at this position.
In addition, since the conveying speed is high in the bottle regulating conveyor 102, the bottles 5 that have been densely continuous in the bottle supplying conveyor unit 101 are conveyed at a distance from each other, and stop in contact with the final end stopper 123. , The subsequent bottles 5 abut against the previously stopped bottles 5 and stop sequentially. The stopped bottles 5 are stopped while sliding the bottom surface on the moving conveyor 121.
[0009]
Next, when the bottle counter 4 located upstream of the bottle gripper 102a counts a predetermined number for each lane, one of the conveyors 111a, 111b, and 111c in the lane is stopped. Then, in the lane of the bottle arranging conveyor section 102, the number of bottles 5 slightly exceeding a predetermined number is stopped while sliding on the bottom surface. When all the lanes are in this state, the conveyor 121 of the bottle arranging conveyor section 102 stops.
Next, the gripper 7 descends, grasps the heads of the bottles 5 lined up in the bottle grasping section 102a, and rises to perform the next work such as packing. When the gripper 7 rises, all the conveyors of the bottle feeding conveyor unit 101 and the bottle arranging conveyor unit 102 are started again, and the same operation as described above is repeated.
[0010]
【The invention's effect】
As described in detail above, according to the present invention, when a predetermined number of bottles enter each lane of the bottle grasping unit, one of the conveyors of the lane of the bottle feeding conveyor unit is stopped. In this lane, there is no pressing force of the bottles in the upstream bottle supply conveyor, and furthermore, bottles are conveyed at intervals in the bottle arranging conveyor, so the conveyor in the bottle supply conveyor stops. In this case, the number of bottles in the corresponding lane of the bottle conveyer section is limited to a number slightly exceeding a predetermined number, the pressing force received by the bottles in the bottle gripping section is kept to a minimum, and the above-mentioned conventional problem is solved. .
