DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insertion device and an insertion method for automatically inserting a thin plate into a predetermined position of a conveyed object.

[0002]

In general, when a predetermined number of products are packed in a packaging case for a predetermined number of products or packed in a shipping case for a transportation or the like and shipped from a manufacturing factory or the like, the products are packed in a case. In order to make the product name and the like of the product visible from the outside, a thin plate such as a display board that describes the product name and type is inserted into the position visible from the outside of the case. I have.

An example of an apparatus for inserting a thin plate such as a display board into a case filled with a product when the product is shipped from a factory is, for example, a bottled beer when a bottled beer is shipped from a beer factory. There is an identification card automatic insertion device that automatically inserts an identification card in which a beer product name is described in a case.

[0004] Such an identification card automatic insertion device has been disclosed in Japanese Unexamined Utility Model Publication No. 3-113353, Japanese Utility Model Publication No.
Japanese Patent Publication No. 30496 and Japanese Patent Publication No. 7-71966.

[0005] The automatic identification card insertion device described in Japanese Utility Model Laid-Open No. 3-113353 hangs a shooter for holding an identification card in an upright state above a case in which products are packed and conveyed. Take out the identification cards one by one from the card holder by suction cup and insert them, hold them once by the stopper attached to the lower end of the shooter, and release and hold the stopper when the case is transported The identification card is automatically inserted into the case.

However, in this conventional identification card automatic insertion device, since the identification card is inserted into a predetermined position of the moving case, it is difficult to time the release of the stopper and the transfer speed of the case. Therefore, there is a possibility that the insertion position in the case and the falling position of the identification card are shifted.

The automatic identification card insertion device described in Japanese Utility Model Publication No. 7-30496 has an acceleration roller at the lower end of a shooter holding the identification card, in addition to the configuration of the insertion device described above. When the identification card is dropped, the falling speed of the identification card is increased by the accelerating roller so as to accurately insert the identification card into a predetermined insertion position in the case.

However, even in the conventional identification card automatic insertion device, it is not possible to eliminate the difficulty in setting the timing between the release of the stopper and the carrying speed of the case. Cannot be completely prevented from falling from the falling position.

The identification card automatic insertion device described in Japanese Patent Publication No. 7-71966 relates to a case where a shooter holding the identification card has been conveyed in order to facilitate the timing of dropping the identification card. At the same time, slide at the same speed as this case, release the locked state of the identification card held with this slide,
The identification card is inserted into a predetermined insertion position in the case.

However, in this conventional identification card automatic insertion device, the stopper attached to the device body side comes off from the lower end opening of the chute at the same time as the slide of the chute starts, so that the identification card held in the chute cannot be moved. Immediately after the slide starts, the identification card in the chute is dropped with little acceleration in the case transport direction, and the predetermined insertion position in the case and the drop position of the identification card Cannot be completely prevented.

As described above, when inserting a thin plate such as an identification card into a case where products are packed and conveyed, the thin plate is placed at a predetermined position of the case because the case is moving. There is a problem that it is difficult to insert it securely. Furthermore, as for the device that automatically inserts a thin plate into the case that is conveyed as described above, it is often conveyed continuously with the case in contact with the case. It is necessary to be able to insert an object, and it is required that the device be small in size to secure an installation space.

The present invention has been made in order to solve the problems of the above-mentioned conventional thin plate insertion apparatus. That is, the present invention is intended to insert a thin plate into a case where products are packed and conveyed,
An object of the present invention is to enable a thin plate to be reliably inserted into a predetermined position of a case while moving the case.

[0013] Further, the present invention is to ensure that a thin plate can be inserted into a case even when the cases packed with products are continuously conveyed in contact with each other. It is another object of the present invention to reduce the size of a device for inserting a thin plate as compared with a conventional device.

I have.

According to a fifth aspect of the present invention, there is provided a method of inserting a thin plate-like object into a case where a machine frame arranged above a carrying member for carrying a case packed with products is transported. At the position opposite to the required position, the sheet-like object holding member is slidably attached in the direction parallel to the conveying direction of the conveying member, and the sheet-like object supply mechanism that supplies the sheet-like object to the sheet-like object dropping mechanism is provided on the machine frame. Attachment, a thin plate-like material supply mechanism inserts the thin plate between the first holding member and the second holding member of the thin plate holding member, and attaches the thin plate to the second holding member. When the case is conveyed by the conveying member and the case is conveyed by the conveying member, the lever member having the upper end mounted so as to slide integrally with the thin plate holding member in the direction in which the lower end is inserted into the case. Turning Then, the thin plate holding member is slid together with the case at the same speed by engaging the lever member with the rear inner wall of the case, and after the thin plate holding member starts sliding, the second holding member is moved in a required section. After the slide member is slid together with the first holding member in a direction parallel to the conveyance direction of the conveyance member, the second holding member is slid in a direction perpendicular to the conveyance direction of the conveyance member to release the locking state of the thin plate-like object by the stopper member. Then, the thin plate is put into the case, and after the thin plate is put into the case, the lever member is rotated in a direction in which the lower end portion is separated from the inside of the case to release the engagement state with the rear inner wall of the case. After the engagement with the case is released, the thin plate-like object holding member is slid to the upstream side in the conveying direction of the conveying member and returned to the original position.

According to the first and fifth aspects of the invention, the thin sheet is inserted between the first holding member and the second holding member of the thin sheet holding member by the paper feeding mechanism. The thin plate-like object inserted between the holding member and the second holding member is locked by a stopper member provided on the second holding member and held between the first holding member and the second holding member.

In this state, when the case packed with the product is conveyed below the thin plate holding member by the conveying member, the lever member attached to the thin plate holding member so as to slide integrally therewith is provided. The lower end is rotated from the upper end thereof into the case to be conveyed, and is engaged with the rear inner wall of the case. Then, by the engagement between the lever member and the case, the thin plate-like object holding member is slid at the same speed integrally with the case.

After the start of sliding of the thin plate-like object holding member,
In a required section, the second holding member is slid together with the first holding member in a direction parallel to the transport direction of the transport member. After passing through the required section, the second holding member is moved in the transport direction of the transport member. It is slid in orthogonal directions. With this, the stopper member is slid together with the second holding member in a direction perpendicular to the conveying direction of the conveying member to release the locked state of the thin plate, and the stopper is held between the first holding member and the second holding member. The thin sheet falls and is inserted into a predetermined position in the case.

Then, after the thin plate-like object is loaded, the lever member is rotated in the opposite direction to be separated from the inside of the case, whereby the state of engagement with the rear inner wall of the case is released.

Thereafter, the thin plate-like material holding member is returned to the original position after being slid to the upstream side in the transport direction of the transporting member, and the thin plate-like material supply mechanism moves between the first holding member and the second holding member. And waits for the case where the thin plate is inserted again and transported next.

As described above, according to the first and fifth aspects of the invention, the thin plate holding member for holding the thin plate to be inserted into the case is packed and conveyed by the engagement of the lever member. The case is integrated with the case and slid in the direction of conveyance of the conveyance member at the same speed, so that the case is relatively stationary with respect to the case. By maintaining the state, when the holding state is released and the sheet-like object is dropped, the sheet-like object is sufficiently accelerated to the carrying speed of the case, and after the drop, the sheet-like object remains in the conveying member. Since it falls while drawing a parabola while traveling at the same speed in the transport direction, it is possible to reliably insert the thin plate-shaped object into a predetermined position of the case.

Further, the connection between the sheet-like material holding member and the case to be conveyed is made by connecting the lower end portion of the lever member which rotates about the upper end portion to the rear inner wall of the case where the lever member enters the case and is conveyed. Since the engagement is performed, even when the cases are continuously conveyed in a state where the cases are in contact with each other, the space for inserting the lever member is always secured, so that the case is conveyed to the thin plate holding member. Thus, the connection with the case can be reliably performed, so that it is not necessary to transport the case at an interval as in the related art, and the thin plate can be reliably inserted. Further, since the connection and the release of the thin plate-like object holding member and the conveyed case are performed only by the rotation of the lever member, the apparatus can be made smaller than the conventional one.

According to a second aspect of the present invention, there is provided a thin plate inserting apparatus according to the first aspect, wherein the thin plate holding member of the thin plate dropping mechanism is transported by a transport member. A pair of first and second holding members of the pair of thin plate-like object holding members are arranged so as to extend in parallel with the conveyance direction of the conveyance member.

When the claw plates 13H1 and 13H1 'are advanced again into the card holder 13A by the operation of H2, the cylinder 13
The pressing plates 13G1 and 13G1 'are opened by the operation of G2, and the holding state of the knowledge paper W is released. Then, when the knowledge band paper W sandwiched by the pressing plates 13G1 and 13G1 'falls to the position of the claw plates 13H1 and 13H1', the pressing plates 13G1 and 13G1 'are closed again, and the dropped knowledge band paper W is removed. Knowledge paper W stacked on top
Side is pinched.

In this manner, the knowledge paper W is dropped by a fixed amount at a time, temporarily locked by the knowledge paper locking claw 13I, and the knowledge paper W at the lowermost end is sucked by the suction cup 13D.

After the wrapping paper W is sucked by the suction cup 13D, the arm 13C is turned downward (counterclockwise in FIG. 7) by the stepping motor (not shown) via the gear box 13E, so that the wrapping paper is drawn. The suction cup 13D that has absorbed W is moved to the position where the knowledge band paper falls (indicated by the dashed line in FIG. 7). At this time, the knowledge paper W is pulled out from the card holder 13A one by one from between the knowledge paper locking claws 13I.

The knowledge band falling position is located directly above the holder H of the knowledge band drop mechanism 12. At this knowledge band falling position, the knowledge band paper W sucked by the suction cup 13D is held vertically. You.

When the suction cup 13D comes to the position where the paper is dropped, the suction state of the suction cup 13D by the compressor is released by switching the open / close valve, and the paper W is removed.
Is dropped, and the knowledge paper W is held by the holder H of the knowledge paper drop mechanism 12.
Between the fixed plate H1 and the slide plate H2.

At this time, the cam roller H13
Therefore, the slide plate H2 is located at a position close to the fixed plate H1 by the urging force of the springs H5 and H6. For this reason, the falling paper band W is inserted between the guides H9 and H10 and between the pair of brackets H8, and is held in the holder H by locking the lower edge thereof by the paper band holding shaft H11. Is done.

The above-described operation of inserting the knowledge paper W is similarly performed in any of the holders H arranged on both sides of the machine casing 11. As described above, when the beverage bottle case K ′ is conveyed by the belt conveyor V in a state where the knowledge paper W is held by the pair of holders H of the knowledge paper dropping mechanism 12, the beverage bottle is processed in the following procedure. The knowledge paper W is dropped into the case K ′.

That is, the upper frame on the upstream side of the transported beverage bottle case K ′ is detected by the case arrival sensor PH2.
When the upper frame on the downstream side is detected by the case arrival sensor PH1 and the side surface is detected by the case arrival sensor PH3, and all the sensors are turned on, the cylinder C1 for lever is operated and the piston rod c1 is retracted into the cylinder. The lever 12G is rotated clockwise in FIG. 6 (from the state of the two-dot chain line to the state of the solid line) around the shaft frame 12D1 via the arm 12H, the sleeve 12E and the arm 12F for the lever. The lower end is fixed vertically in a state of being inserted into the beverage bottle case K ′.

When the beverage bottle case K 'further advances in the transport direction with the lever 12G fixed vertically, the lower end of the lever 12G is placed on the inner wall surface of the upper frame on the downstream side of the beverage bottle case K'. And is urged downstream by the beverage bottle case K '.

When the lever 12G is urged to the downstream side, the sliders 12B1 and 12B2 slide with respect to the shaft 12A, whereby a pair of plates 12C and a pair of holders H on both sides are interposed via the shaft frame 12D1.
However, at the same speed as the beverage bottle case K ', the shaft 12A
Along the transport direction to the downstream side in the transport direction.

Each holder H holding one sheet of knowledge paper W inside thereof at the initial stage in which the lever 12G is slid in the downstream direction after engaging with the beverage bottle case K ', Since the cam roller H13 rolls on the first cam surface H14a of the cam H14, the slide plate H2
Is slid parallel to the conveying direction of the belt conveyor V,
As a result, the knowledge paper W is locked by the knowledge paper holding shaft H11 and remains held between the slide plate H2 and the fixed plate H1.

When the holder H is further slid to the downstream side, the cam rollers H13 ride on the second cam surfaces H14b of the cams H14 and are urged outward in a direction perpendicular to the conveying direction of the belt conveyor V, thereby causing the bracket H1 to move.
2, the slide plate H2 is slid outward at right angles to the conveying direction of the belt conveyor V.

As a result, the slide plate H2 is separated from the fixed plate H1, and together with the slide plate H2, the knowledge paper holding shaft H11 is slid in the direction away from the fixed plate H1 to hold the lower end of the knowledge paper W. It comes off the edge, and is thereby dropped from between the fixed plate H1 and the slide plate H2.

At this time, the holder H and the beverage bottle case K 'are engaged with each other by the lever 12G and move integrally, so that the position of the beverage bottle case K' in which the paper is inserted is located immediately below the holder H. In a relatively stationary state, and the knowledge paper W is held in the holder H and a required section from the start of the slide (a section in which the cam roller H13 rolls on the first cam surface H14a) is integrated with the holder H. Of the beverage bottle case K ', it moves at the same speed as the transport speed of the beverage bottle case K', and falls while drawing a parabola. It is thrown into.

After dropping the paper, the holder H is moved further downstream by the cam roller H13 rolling on the third cam surface H14c of the cam H14 so that the slide plate H2 is separated from the fixed plate H1. Slided. At this time, the piston rod c2 of the slide cylinder C2 is urged downstream through the cylinder shaft 12I and pushed into the cylinder body, and the holder H
Is slid to a predetermined position, the rear end of the piston rod c2 comes into contact with the reed switch SW1, and when the reed switch SW1 is turned on, the lever cylinder C1 is operated, the piston rod c1 is extended, and the lever 12G is moved downstream. By rotating the lever 12G in the direction (counterclockwise in FIG. 6), the engagement state between the lever 12G and the downstream upper frame of the beverage bottle case K ′ is released.

As a result, the beverage bottle case K ′ is transported to the downstream side apart from the paper band dropping mechanism 12. When the reed switch SW1 is turned on, the slide cylinder C2 is actuated and the piston rod c2 is extended, whereby the holder H of the holder band release mechanism 12 disengaged from the beverage bottle case K 'is disengaged from the shaft. After being slid to the upstream side along 12A, it is returned to the original standby position, and the front end of the plate 12C is
By being in contact with J, it is positioned at the standby position.

When the mechanism paper dropping mechanism 12 is returned to the standby position, the cam roller H13 is returned from the third cam surface H14c of the cam H14 to the first cam surface H14a. H5 and H6
The stopper shaft H7 is urged to slide in a direction approaching the fixed plate H1, and is positioned in a state where a gap h is opened between the stopper shaft H7 and the fixed plate H1 when the tip of the stopper shaft H7 contacts the fixed plate H1.

Then, the holder H of the knowledge band dropping mechanism 12 located at the standby position is placed in the above-described procedure by the above-described procedure.
The knowledge paper supply mechanism 13 inserts the knowledge paper W one by one, and waits until the next beverage bottle case K ′ is conveyed.

As shown in FIG. 2, the lower end edge of the beverage bottle case K ′ between the inner wall surface on both sides and the beverage bottle B ′ has passed through the insertion device 10 as described above. Each of the knowledge sheets W is inserted one by one in a state of being placed on the partition plate of K ′. The name of the beverage or the like described on the surface facing the outside of the knowledge paper W can be visually recognized through the window Ka formed on the side of the beverage bottle case K ′.

As described above, the insertion device 10
One sheet of knowledge paper W is inserted into each of the insides of both sides of the beverage bottle case K ′ sequentially conveyed by the belt conveyor V.
