Abstract

PURPOSE:To align appearance phase of a cylindrical battery continuously and at high speed without manpower by detecting a reference mark of the cylindrical battery with a detection sensor and by operating a positioning unit. CONSTITUTION:A detection sensor 7 runs synchronously with a corresponding cylindrical battery 2 with detecting action, while the cylindrical battery 2 makes at least one rotation by a moving motion of a belt 6a. This rotation is monitored by the detection sensor 7 and a signal when a reference mark or a junction line of a case can is detected is sent to a electromagnetic solenoid 8a of a positioning unit 8. By this, the electromagnetic solenoid 8a pushes up and holds a plunger 8b, disconnects contact between the cylindrical battery 2 and the belt 6a and stops rotation of the cylindrical battery 2 for positioning. Moreover, the solenoid holds the cylindrical battery 2 on a conveying table 9 with a pressing brush so that the cell will not rotate and conveys it to a next film packaging process with a carrier 5.

The cylindrical battery 2 supplied from the chute 1 is sent to a star-shaped rotary feeder 3 that sorts while rotating.

The star-shaped rotary feeder 3 divides the cylindrical batteries 2 to be supplied into a group of packages (in this embodiment, four cells are grouped into one group), so that the rotating disk is rotated. A plurality of recesses 3a corresponding to the cylindrical case of the battery 2 are provided around the periphery in a number unit corresponding to the number of packages, and the cylindrical battery 2 sent from the chute 1 includes the chute 1 and the recess 3a.
And is sent in the rotation direction indicated by the arrow A in the figure.

A pedestal 4 is provided below the star-shaped rotary feeder 3 in the horizontal direction, and in parallel with the pedestal 4, the peripheral speed of the star-shaped rotary feeder 3 is the same as the direction of the arrow B in the figure. A plurality of carriers 5 that are driven and moved by are connected and provided in an endless chain shape at equal intervals.

Since these carriers 5 convey the cylindrical batteries 2 divided by the star-shaped rotary feeder 3 in units of the number of packages in a set number on the pedestal 4 in the direction of arrow B, the adjacent carriers 5 are They are arranged at a pitch dimension interval corresponding to the number of packages, and a set of cylindrical batteries 2 are sandwiched between them to move.

That is, the cylindrical batteries 2 divided by the star-shaped rotary feeder 3 into units of the number of packages are sent to the lower part of the star-shaped rotary feeder 3 and separated from the chute 1 when the star-shaped rotary feeder 3 moves. It is sandwiched between two adjacent carriers 5 that move at the same speed as the peripheral speed, and is sent horizontally on the receiving table 4 in the right direction in the figure.

A pair of belts 6a for rotating a battery driven by a battery rotating mechanism 6 rotating in a direction indicated by an arrow C in the drawing are provided downstream of the end of the cradle 4 in parallel with the traveling direction of the carrier 5. Is provided.

A set of cylindrical batteries 2 sandwiched between two adjacent carriers 5 on the cradle 4 and sent are placed on the pair of belts 6a after the end of the cradle 4 and further carried by the carrier 5. It is sent to the right in the figure.

As shown in FIG. 2, the pair of belts 6a holds both end portions of the cylindrical battery 2 to be fed, and the cylindrical battery 2 placed on these belts 6a is placed between the belt 6a and the belt 6a. Due to the contact friction, the carrier 5 is conveyed while rotating following the movement of the belt 6a.

Above the belt 6a are arranged and connected in an endless chain so as to correspond to the respective cylindrical batteries 2 to be fed, and are driven by a driving mechanism (not shown) to synchronize with the conveyance of the cylindrical batteries 2. A plurality of detection sensors 7 utilizing light, which rotate and move, are provided.

The detection sensor 7 detects the reference mark provided on the outer peripheral surface of the case of the cylindrical battery 2 or the joining line of the case can to align the external phase of the cylindrical battery 2.

Further, a pair of belts 6 of the battery rotating mechanism 6

The positioning unit 8 is also connected in an endless chain and is rotated by a drive mechanism (not shown).

The positioning unit 8 is composed of an electromagnetic solenoid 8a and a plunger 8b for energizing or de-energizing the solenoid current which moves up and down in the electromagnetic solenoid 8a to push up the battery. The electromagnetic solenoid 8a runs in synchronization. Upon receiving the detection signal output of the detection sensor 7, the plunger 8b is pushed up by the electromagnetic action.

The tip of the upper portion of the plunger 8b for pushing up the battery improves the contact with the cylindrical battery 2 in order to hold the cylindrical battery 2 stably when pushing up the cylindrical battery 2 and separating it from the belt 6a. With a V-shaped groove,
A permanent magnet is embedded in this tip portion to magnetically attract the case of the cylindrical battery 2.

The detection sensor 7 starts the detection operation when the belt 6a of the battery rotating mechanism 6 moves to the left end in the figure. While traveling in the right direction in the figure in synchronization with the corresponding cylindrical battery 2 while performing the detection operation, during this traveling, the cylindrical battery 2 is rotated by the movement of the belt 6a in the direction of the arrow C, and is rotated at least once. .

The rotation is detected by the detection sensor 7, and when the reference mark or the joining line of the case can is detected, the signal is sent to the electromagnetic solenoid 8a of the corresponding positioning unit 8 to be operated. As a result, the electromagnetic solenoid 8a pushes up the plunger 8b, pushes up and holds the cylindrical battery 2 at its upper end, disconnects the contact between the cylindrical battery 2 and the belt 6a, and stops the rotation of the cylindrical battery 2. Determine the position. The moving speed of the belt 6a of the battery rotating mechanism 6 is
The speed is set so that the cylindrical battery 2 rotates at least once while moving to a predetermined position.

When the cylindrical battery 2 is conveyed to a predetermined position and downstream from the right end of the belt 6a in the figure, the current of the electromagnetic solenoid 8a of the positioning unit 8 is cut off,
Return the plunger 8b. When the plunger 8b is lowered, the cylindrical battery 2 is placed on the carrier pedestal 9 provided on the right end of the belt 6a in the figure and thereafter, and then the carrier 5 is carried by the carrier 5 to the film packing process which is the next process. .

The present invention is not limited to the above-mentioned embodiments, and can be modified and carried out without changing the gist.

In the above embodiment, as the positioning unit,
I explained that the electromagnetic solenoid drives the plunger directly, but since it is a cylindrical battery with a small diameter such as AAA, AAA, etc., if it is difficult to place the electromagnetic solenoid directly under the battery, It is also possible to implement a mechanism in which electromagnetic solenoids, which require a large space, are alternately provided on the left and right in the battery transport direction and the plunger is driven via a lever or the like. Further, the plunger can be returned mechanically by using a cam mechanism or the like as the positioning unit moves. Further, in this embodiment, the case where one set is packaged with four pieces is described, but it can be carried out regardless of the number of packaging units. Furthermore, the present invention can be applied to the case where the battery is housed in a box.
