Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic counting and arranging device for pads that counts pads, arranges them in multiple stages and multiple rows, and sends them to the next process.

Conventionally, multiple rows of pads are stacked in multiple rows and assembled into a fixed unit, and when this assembled pad group is to be wrapped or hung with a string, for example, the pads are placed in a fixed unit on wrapping paper, etc. The pads are arranged manually before packaging, or the pads are manually arranged at a predetermined position on a binding machine, etc., and then the binding machine is turned on to tie strings or the like.

However, due to manual work as described above,
Stacking and arranging the pads has the problem of poor work efficiency, and when packaging and stringing are performed using automatic machines, it is difficult to stack and line up the pads. The machine had to be kept on standby while the stacked pads were being arranged, which caused the problem that it was not possible to save labor.

In addition, when using manual labor, it is necessary to maintain a good working environment, and it is necessary to secure specialized workers for stacking and arranging the stacks, which leads to a rise in work costs such as work equipment and personnel costs. There was also a problem.

The present invention has been made to solve the above problems, and by automating the stacking and alignment of pads, it improves work efficiency, saves equipment and manpower, and reduces work costs. The purpose is to

The automatic pad counting and alignment device according to the present application for achieving the above object is characterized by pad feeding means for horizontally supplying pads at appropriate intervals, and stage counting means for counting the number of pads fed. , a pad receiving means is arranged radially on the periphery of a roller whose rotational axis is disposed in a horizontal direction orthogonal to the pad transport direction and rotates intermittently, and a fixed number of pads supplied by the feeding means are delivered to the pad receiving means. When supplied, the plurality of pads are rotated at a certain angle in a direction in which they are stacked on the circumferential surface of the roller, and by this constant angle rotation or repetition of this rotation, the pads are rotated 90 degrees from the position where the pads are received. a stacked pad transporting means for horizontally transporting a group of pads supplied in a plurality of stacked stages by the stage alignment means; , a row counting means for counting the number of stacked pad groups transferred by the transfer means, and a column for sending out the stacked pad groups arranged in a plurality of rows when the stacked pad groups are transferred by a certain number of rows by the transfer means. The present invention is characterized in that an alignment means is provided.

With the above structure, when the number of pads sequentially supplied by the feeding means reaches a predetermined number, the stage counting means first counts the pads, and the pads are automatically stacked by rotating the stage arranging means. They can be rotated and stacked in tiers. Next, the rows of the stacked pad groups stacked in this tiered state are fed to the row alignment means by the pad transfer means, and during this transportation, the row counting means counts and the stacked pad groups are transferred by a predetermined number of rows. When this happens, the row aligning means is operated to stack and align a certain number of pads and supply them to the next process.

As described above, it is possible to automatically stack a certain number of pads in a stack, and also to automatically arrange the stacked pads into multiple rows, which improves the work efficiency of stacking and arranging the pads. Not only can equipment and human resources be saved, but work costs can be significantly reduced compared to conventional methods.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of an automatic pad counting and alignment device according to the present invention will be described in detail with reference to the drawings.

1 and 2 show an embodiment of the present invention, and in each figure, pads 1 supplied from above are received by a conveyor device 2 and conveyed one after another. The conveyor device 2 consists of a pair of rotating rollers 2a, 2a', a belt 2b welded to the rollers 2a, 2a', and a number of partition plates 2c provided on the belt at regular intervals. The pad 1 is inserted between the partition plates 2c on the belt 2b and is fed in as the belt 2b rotates.

At the end of the conveyor device 2, pad feeding means 3 is provided for separating the pads 1 sent by the conveyor device for a suitable period and feeding them individually.
The pad feeding means 3 includes a horizontal plate 3a on which the pad 1 slides, a belt 3b stretched on both sides of the width of the horizontal plate 3a, and a pair of rollers 3c, 3c for rotationally rotating the belt in the pad transport direction. ', and a pair of fixed guides 3d, 3d' for pressing the belt 3b against both sides of the pad 1. The pad transfer speed by rotation of belt 3b is the same as that of belt 2.
Since the pad transport speed is set higher than the pad transport speed by rotary rotation in b, when the pads 1 are fed by the pad feeding means 3, the pads 1 are spaced apart from each other at appropriate intervals.

A stage counting means 4 for counting the number of pads 1 fed at appropriate intervals is provided at a suitable location on the pad feeding means 3. The stage counting means uses, for example, a phototube to detect and count how many pads 1 have been sent by counting the number of pads 1 that are blocked when the pads 1 pass between the light emitting means and the light receiving means. It is something to do.

At the circumferential end of the pad feeding means 3, a rotation axis is arranged in a horizontal direction perpendicular to the pad transport direction, and a plurality of pad receiving means 5b are arranged radially on the circumference of a roller 5a which rotates intermittently. Means 5 are provided. The rotation of the roller 5a is controlled by providing a rotary plate 5c concentrically with the roller 5a and rotating together with the roller 5a, and penetrating the rotary plate 5c with a plurality of holes 5d at equal intervals on the same radius.
d is detected by phototube means 5e, and when light passes through 5d, the rotation of the roller 5a is stopped by a clutch brake, thereby allowing intermittent rotation at regular intervals. and,
The rotation of the roller 5a is started when the number of pads 1 sent by the pad feeding means 3 reaches a preset constant number (for example, 3 in this embodiment), that is, when a constant number of pads 1 are delivered. When the pad is fed into the pad receiving means 5b, it is rotated by a certain angle, 45 degrees in the illustrated example. Therefore, by repeating the intermittent rotation of the roller 5a multiple times (twice in this case), a plurality of pads can be attached at a position rotated 90 degrees from the pad receiving position (position A in the diagram) (position B in the diagram). The pad 1 is sent out in a state where it is pressed. The pads 1 arranged in a row at position A are rotated 90 degrees so as to be stacked, so that the pads 1 are stacked in multiple stages and sent out.

A mechanism for rotating and moving the rows of pads to stack them in the manner described above, further collecting them in a plurality of rows and supplying them to the next process will be described.

6 is a pad transfer means, and the step alignment means 5
One end is facing the pad delivery position. The pad transfer means 6 is for transporting the stacked pads 1 sent out from the stack alignment means 5 to an appropriate position in the stacked state, and has a horizontal plate 6a on which the pads 1 slide. , a pair of rotatable belts 6 provided on both sides of the horizontal plate 6a.
b, 6b', a pair of rollers 6c, 6c' that rotate the belts 6b, 6b', and fixed guides 6e, 6 that press the belts 6b, 6b' against the pad 1.
It consists of e′. By rotation of the belts 6b, 6b', the pads 1 are transported horizontally to position C while maintaining the stacked state.

A group of stacked pads 1 is intermittently transferred to position C, but when a subsequent pad group arrives at position C, it pushes the previous pad group that has already arrived at position C forward. In this way, the pad groups are pushed forward one after another, and when a preset number of pad groups arrive at position C,
A row counting means 7 for counting the number of rows of stacked pads is provided at the position where the foremost pad group is pushed aside. The row counting means 7 uses a phototube and detects that a set number of pad groups have arrived at position C when the optical path is blocked by the foremost pad group.

Position C is on the row alignment means 8, which arranges the stacked pads 1 sent by the pad transfer means 6 into a plurality of rows, and separates pad groups stacked in the plurality of stages and into the plurality of rows. This state is maintained and sent to the next process. The number of columns aligned by the column alignment means 8 is the number of columns counted by the column counting means 7. The row alignment means 8 includes a horizontal plate 8a on which the pad group slides, a pair of chains 8b, 8b' rotatably provided on both sides of the horizontal plate 8a, and the chains 8b, 8b'.
8b', and a sprocket 8d for intermittently rotating the chains 8b, 8b'.
8d', 8d''. When the row counting means 7 counts the preset number of rows, the sprockets 8d, 8d', 8d'' begin to rotate by a certain angle, and the chains 8b, 8b' are rotated by a certain distance. Proceed. At this time, the claw means 8 attached to the chains 8b, 8b'
By transporting a group of pads a certain distance and repeating the above operation, the group of pads c is intermittently transported to the next process, for example, a packaging process, while maintaining the row of pads.

As described above, the present invention can automatically stack a certain number of pads in stacks, and automatically arrange the stacked pads into multiple rows.

Since the present invention has the above-described structure and operation, the pad alignment work, which was conventionally done manually, can be automatically performed, thereby saving labor and improving work efficiency. be able to. Therefore, it is possible to significantly reduce work costs compared to the conventional method.
