Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular article remover for removing a tubular article such as a tube from a box.

Conventionally, conventionally, a box containing a large number of tubular articles is supplied to a predetermined carry-in position as an anchor of a tubular article, and a plurality of gripping heads arranged in a row are arranged in a tubular article in the box. Are respectively inserted and held, and then, when each gripping head is conveyed to an unloading position, each tubular article held by each gripping head is detached (West German Patent No. 3631891). ).

[Problem to be Solved by the Invention] However, in the above-described conventional apparatus, the tubular article is taken out from the box while reciprocating one set of gripping heads between the carry-in position and the carry-out position. Has the disadvantage that the processing capacity of the is small.

Means for Solving the Problems In view of such circumstances, the present invention provides a movable frame rotatably provided, a plurality of sets of gripping heads provided at equal intervals in a circumferential direction of the movable frame, and A rotation drive mechanism for intermittently rotating the frame to sequentially position one of the sets of gripping heads at the loading position and the other set of gripping heads at the unloading position, and a tubular drive provided at the loading position to accommodate the tubular article. Conveyor, which intermittently conveys the selected box at a required pitch in a tilted state, detaching means provided at the unloading position, for removing the tubular articles held by the holding heads from the respective gripping heads, and And an article conveying means for conveying the cylindrical article removed from each gripping head, wherein the gripping heads of each set are arranged in at least one row and are movable back and forth to the movable frame. The gripping head of any of the sets, which is located at the carry-in position, is advanced to hold the tubular article, and is retracted to take out the tubular article from the inside of the box. The other set of gripping heads, the tubular article is removed from the gripping head by the removing means, and each gripping head is sequentially positioned at the carry-in position and the carry-out position. It is an object of the present invention to provide a tubular article uncertainer characterized in that a tubular article is carried out a plurality of times from one box while the articles are stacked below an inclined box.

According to the above-described configuration, in any of the gripping heads located at the carry-in position, the gripping heads arranged in a row are advanced to hold the tubular articles in the box, respectively, The tubular article is retracted so as to be taken out of the box. At this time, since the box is in an inclined state, the tubular articles remaining in the box are stacked under the inclined box by its own weight, whereby the tubular articles remaining in the box are removed. It is possible to prevent the box from falling down and becoming unremovable.

At the same time, the tubular article is detached from the other set of gripping heads already held at the carry-out position while holding the tubular article by the detaching means. It will be carried out by means.

In this way, when the holding of the tubular article is performed at the carry-in position and the holding of the tubular article is released at the carry-out position, the movable frame is intermittently rotated by the rotary drive mechanism, and the empty gripping head is rotated. Is moved to the carry-in position, and the gripping head holding the tubular article is moved to the carry-out position. In addition, the box transport conveyor advances the box at a required pitch, thereby supplying a new tubular article to a position in front of the empty gripping head, and the same operation is repeated thereafter. Therefore, the processing capability of the anchor can be increased as compared with the related art.

"Example" Hereinafter, the present invention will be described with reference to the illustrated example. In FIG. 1, an anchor 1 is provided with an empty space corresponding to one horizontal row in a direction orthogonal to the conveying direction of the box 2 from inside a cardboard box 2 having an open top. The tubular articles 3 (see FIGS. 3 and 4) can be sequentially taken out.

As shown in FIGS. 3 and 4, the empty tubular article 3 before being filled with a toothbrush or the like abuts a cap 4 screwed in advance on a mouth thereof on the bottom 2a of the box 2. It is stored in the box 2 in the inverted state. The cylindrical articles 3 housed in the boxes 2 are made of a soft synthetic resin, and are each maintained in a cylindrical shape by its own elasticity.

In the present embodiment, the cylindrical articles 3 are accommodated in the box 2 with 11 pieces in a row in a direction orthogonal to the transport direction of the box 2 and the cylindrical articles 3 in each row adjacent to the box 2 in the transport direction. 3
Are shifted in the column direction at a pitch of half the pitch P between the cylindrical articles 3, whereby the cylindrical articles 3 are housed in the box 2 in a staggered manner.

As shown in FIG. 1, the boxes 2 containing the tubular articles 3 in a staggered manner are arranged from a horizontally arranged fixed conveyor 6 constituting a box transport conveyor 5 to an inclined elevator 8 via an inclined conveyor 7. The cylindrical conveyor 3 is conveyed to the carry-in position A of the cylindrical article 3 by the elevating conveyor 8, and is positioned at the carry-in position A at a required pitch P '(see FIG. 3) smaller than the pitch P. Is being advanced forward. The lifting conveyor 8 includes:
When the height of the tubular article 3 is changed, the tubular article 3 can be moved up and down diagonally while maintaining a constant inclined state according to the height.

Above the carry-in position A, a movable frame 13 is attached to a rotating shaft 12 rotatably supported on a fixed frame 11, and the movable frame 13 extends three radially from the rotation center of the rotating shaft 12. Branch parts 13A, 1 arranged at equal intervals
3B, 13C, and transfer mechanisms 14A, 14B, which take out the tubular article 3 from the inside of the box 2 at each of the branch portions 13A to 13C, respectively.
14C is provided.

The movable frame 13 is a rotary drive mechanism 15 (see FIG. 2).
Is rotated intermittently in 1/3 rotations, that is, every 120 degrees in a certain direction. For example, when the first transfer mechanism 14A is located at the carry-in position A, the second transfer mechanism 14B is moved out of the carry-out position B. And the third delivery mechanism 14C
At the play position C, and by the next intermittent rotation, the first transfer mechanism 14A is moved to the play position C, and the second transfer mechanism 1 is moved to the play position C.
4B can be located at the carry-in position A, and the third delivery mechanism 14C can be located at the carry-out position B.

Each of the delivery mechanisms 14A to 14C has the same configuration. The eleven gripping heads 19 provided in each of the delivery mechanisms 14A to 14C are arranged in a horizontal row of the cylindrical articles 3 in the box 2 at the carry-in position A. Are respectively inserted forward to hold each tubular article 3,
Further, the tubular article 3 held by the retreat can be taken out of the box 2.

As shown in FIGS. 5 and 6, each of the gripping heads 19 includes a rod 20 disposed along the above-described reciprocating direction, and a flat conical guide member 21 attached to the distal end of the rod 20. And an elastic member 22 made of a disc-shaped rubber or the like attached to the rear of the guide member 21. When the gripping head 19 moves forward, the guide member 21 is loosely fitted into the tubular article 3 with a small gap, and the elastic member 22 is press-fitted into the tubular article 3 so that the elastic member 22 and the tubular The cylindrical article 3 can be held by the frictional force with the cylindrical article 3.

Then, as shown in FIG. 1 and FIG.
The cylindrical article 3 which has been intermittently conveyed to the unloading position B through the play position C is pulled out from the gripping head 19 by the comb-like member 25 (FIG. 2) provided at the unloading position B as a removing means. The cylindrical article 3 pulled out from each gripping head 19 falls horizontally and in parallel onto the article transport conveyor 26, and is transported by the article transport conveyor 26 to the next step.

That is, as shown in FIG. 7, the rods 20 of the gripping heads 19 are respectively positioned in the gaps 25a of the comb-like members 25 when the transfer mechanisms 14A to 14C are rotated and positioned at the unloading position B. When each gripping head 19 is inserted and retracted in that state, the tubular member 3 held by each insertion head 19 comes into contact with the tooth portion 25b of the comb-like member 25 and is pulled out from each gripping head 19. It has become.

At this time, the elastic member 22 passes through the gap 25a of the comb tooth-shaped member 25 while being elastically deformed, and the guide member 21 moves through the gap 25a so that it can pass through the gap 25a.
(See FIGS. 5 and 6).
This results in a flat conical shape.

Further, as shown in FIG. 6, the elastic member 22 has an opening formed of a through hole for communicating the inside of the tubular article 3 with the atmosphere.
22a is formed to prevent the inside of the tubular article 3 from becoming negative pressure when the elastic member 22 is pulled out of the inside of the tubular article 3, and the soft tubular article 3 made of a soft synthetic resin or the like is formed. At the same time, it is possible to prevent deformation due to negative pressure and at the same time to smoothly pull out. As shown in FIG. 8, the opening 22a 'formed in the elastic member 22' does not need to be a through hole, but may be, for example, a notch formed in the outer peripheral portion thereof.

Next, in FIG. 1, when eleven cylindrical articles 3 in a row are taken out of the box 2 by the preceding delivery mechanism 14A, the box 2 is moved by the lifting conveyor 8 to the pitch P '.
With it comes to intermittently advance. Then, the subsequent delivery mechanism 14B rotates the movable frame 13 so that the transfer position A
As described above, the gripping head 19 moves forward and backward to take out eleven cylindrical articles 3 in a horizontal row from the box 2. At this time, the gripping head 19 of the delivery mechanism 14B is displaced in the row direction at a half pitch 1 / 2P, so that even if the tubular articles 3 are staggered in the box 2, the tubular articles 3 are taken out smoothly. You can do it. At this time, since the box 2 is inclined by the elevating conveyor 8, the tubular articles 3 remaining in the box 2 are stacked under the inclined box by its own weight, thereby The tubular article 3 remaining in the box 2 is prevented from falling down in the box and being unable to be taken out.

The box 2 from which all the tubular articles 3 have been taken out and thus emptied is carried out of the elevating conveyor 8 to the outside via the inclined conveyor 9 and the fixed conveyor 10 disposed horizontally, and A new box 2 is carried in to the carry-in position A on the conveyor 8, and the above operation is repeated.

However, each delivery mechanism 14A provided in each branch 13A to 13C
To 14C have the same mechanism, so that the configuration of only one delivery mechanism 14A will be described.
As shown in FIG. 10 and FIG. 10, the delivery mechanism 14A
First guide rail 31 radially arranged and fixed along 3A
Is disposed parallel to the rotating shaft 12 and is engaged with the first guide rail 31 so as to be free to travel.
And a first movable member 32 that moves forward and backward in the radial direction along the first movable member 31.

A second guide rail 33 disposed parallel to the rotating shaft 12 is attached to the first movable member 32, and the second movable member 34 is engaged with the second guide rail 33 so as to be able to travel freely. . Further, the above-mentioned 11
The gripping heads 19 are attached to the second movable member 34 at radially equal positions in the radial direction.

Therefore, by moving the first movable member 32 forward and backward in the radial direction, the gripping head 19 is moved to the cylindrical article 3 in the box 2.
And the second movable member 34
The gripping heads 19 can be moved to a position corresponding to the position of the zigzag cylindrical article 3 in the box 2 by moving the gripping head 19 in a direction parallel to the rotation axis 12 perpendicular to the moving direction. .

Next, a mechanism for moving the first movable member 32 forward and backward will be described. The cam follower 37 attached to the first movable member 32 is slidable in a radially formed slit 38 along the branch portion 13A. Through the fixed frame 11
And is rotatably engageable with a cam groove 40 (see FIG. 11) of a cam plate 39 fixed to the cam plate 39.

As shown in FIG. 11, a movable cam member 41 engaging with the cam follower 37 is located at a position where the cam follower 37 stops when the delivery mechanism 14A is located at the carry-in position A.
The first movable member 32 and the gripping head 19 are moved forward and backward by moving the movable cam member 41 in the radial direction, whereby the cylindrical article 3 is moved out of the box 2.
So that you can take it out.

The cam follower 37 also stops at a position where the cam follower 37 stops when the transfer mechanism 14A is located at the unloading position B.
A movable cam member 42 is provided for engaging with the first movable member 32 and the gripping head by radially retracting the movable cam member 42 from the radially outward position to the inward position.
The retractable operation of the gripping head 19 allows the tubular article 3 held by the gripping head 19 to be pulled out.

The cam groove 40 positions the cam follower 37 in the radially inner position at the carry-in position A and the radially outer position at the carry-out position B, and moves the cam follower 37 radially outward at the carry-out position B. Since it is necessary to move to the next carry-in position A while moving from the position to the inward position, the whole is formed in a substantially spiral shape.

The movable cam member 41 provided at the carry-in position A has a cam groove 41a continuous with the cam groove 40, and the movable cam member 41 is slidable in an elongated hole 43 formed in the cam plate 39 in a radial direction. Is engaged. As shown in FIGS. 9 to 11, the movable cam member 41 has a substantially rectangular movable base.
The movable table 45 is mounted on a pair of guide rails 46 arranged in the radial direction and fixed to the fixed frame 11.
It is mounted so that it can run freely. One end of a driving rod 47 is pivotally connected to the moving table 45, and the other end of the driving rod 47 is linked to a reciprocating mechanism (not shown).

Therefore, when the cam groove 41a of the movable cam member 41 is continuous with the cam groove 40, the movable frame 13
The cam follower 37 of the transfer mechanism 14A rolls in the cam groove 40 with the rotation of the transfer mechanism 14A, and when the transfer mechanism 14A reaches the carry-in position A and stops its rotation, the cam follower 37 moves from the cam groove 40 to the movable cam member. 41 enters the cam groove 41a and stops.

In this state, the reciprocating mechanism advances the first movable member 32 and the gripping head 19 in the radial direction via the moving table 45, thereby holding the tubular article 3 in the box 2 with the gripping head 19. In this state, the reciprocating mechanism retreats the first movable member 32 and the gripping head 19, thereby taking out the tubular article 3 held by the gripping head 19 from the inside of the box 2.

When the first movable member 32 and the gripping head 19 are retracted, the cam groove 41a of the movable cam member 41 is moved to the cam groove 4 of the cam plate 39.
When it is continuously 0, the movable frame 13 rotates and the delivery mechanism 1
The cam follower 37 of the 4A is moved from the cam groove 41a into the cam groove 40, and the cam follower 37 of the succeeding delivery mechanism 14B is positioned in the cam groove 41a.

On the other hand, the movable cam member 42 provided at the unloading position B is also configured in the same manner as the movable cam member 41.
42 has a cam groove 42a and a moving table 49, and the moving table 49 is engaged with a guide rail 50 fixed to the fixed frame 11 so as to be able to run freely. As shown in FIGS. 11 and 12, a cam follower 53 provided at one end of a crank 52 swinging about a shaft 51 is engaged with an engagement groove 49a formed in the moving table 49, and the crank 52 The drive rod 54 connected to the other end of the drive is linked to a reciprocating mechanism (not shown).

In the unloading position B, the movable cam member 42 is advanced while the movable frame 13 is rotating, and the cam groove 42a is moved to the first position.
1 When the transfer mechanism 14A comes to the unloading position B and the rotation thereof is stopped in this state, the cam follower 37 moves from the cam groove 40 to the cam groove of the movable cam member 42. Enter into 42a and stop.

In this state, the reciprocating mechanism retracts the first movable member 32 and the gripping head 19 from the advanced position via the moving table 49, and the gripping head 19 is moved by the comb-shaped member 25 described above.
From the cylindrical article 3. And the movable cam member
When the cam groove 42a continues to the cam groove 40 below the cam plate 39 as the retracted end 42, the movable frame 13 rotates to move the cam follower 37 of the transfer mechanism 14A from the cam groove 42a to the cam groove 40.
When the cam follower 37 of the delivery mechanism 14A is disengaged from the cam groove 42a, the movable cam member 42 is immediately returned to the forward end position, and thereby the subsequent delivery mechanism 14
The B cam follower can be received in the cam groove 42a.

Next, the second movable member is provided at the carry-in position A,
A mechanism for moving the gripping head 19 forward and backward to move the gripping head 19 to a position corresponding to the position of the staggered cylindrical article 3 in the box 2 will be described. In FIGS. 9 and 10, the second movable member 34 is described. A pin 58 is erected on the upper surface of the first movable member 32 via a bracket 57, and the tip of the pin 58 is formed in the first movable member 32.
A tension spring 60 is stretched between the tip of the pin 58 and the first movable member 32 while penetrating the pin 59. The tension spring 60 includes the second movable member 34 and the second movable member 34.
The gripping head 19 provided at 34 is urged to the left, and the adjusting screw 61 screwed to the bracket 57 is brought into contact with the right end face of the second guide rail 33 fixed to the first movable member 32.

Therefore, the second movable member 34 is urged by the tension spring 60 so that the tip end of the adjusting screw 61 normally has the second guide rail 33.
In this state, the eleven gripping heads 19 attached to the second movable member 34 are
Are cylindrical tubes arranged in a horizontal line in a state of contacting the inner wall surface of the box 2 of the leftmost cylindrical product 3 among the eleven cylindrical products 3 in a horizontal line accommodated in the box 2. It is located just above the article 3. At this time, the positioning of each gripping head 19 can be performed by rotating the adjusting screw 61.

On the other hand, in order to position the eleven gripping heads 19 immediately above the tubular articles 3 arranged in a horizontal row while the rightmost tubular article 3 is in contact with the inner wall surface of the box 2. It is necessary to displace the second movable member 34 to the right by half of the pitch P against the tension spring 60. Therefore, as shown in FIG. 9 and FIG.
A cam follower 63 is attached to the left end of the cam follower 63, and is engaged with the cam follower 63 by a cylinder device 64 provided on the fixed frame 11 at a position close to the movement locus of the cam follower 63 as the first movable member 32 moves forward and backward. There is provided a cam member 65 which is moved to a position where it engages and a position where it does not engage.

When the cam member 65 is moved to a position where it engages with the cam follower 63 by the cylinder device 64, the second movable member 34 is displaced rightward by half the pitch P via the cam follower 63. Is available.

Accordingly, when the transfer mechanism 14A is stopped at the carry-in position A and the first movable member 32 is moved forward and backward by the movable cam member 41, the cam member 65 is located at the non-engagement position. 2. Since the cam follower 63 provided on the movable member 34 does not engage with the cam member 65, the gripping head 19 is moved forward and backward while being maintained at the reference position. It is possible to take out the cylindrical articles 3 for one horizontal row of positions.

On the other hand, the first movable member 32 is moved by the movable cam member 41.
When the cam member 65 is located at the engagement position when the advancing and retracting operation is performed, the cam follower 63 engages with the cam member 65, so that the second movable member 34 is opposed to the tension spring 60. The gripping head 19 is moved rightward by a half pitch, so that, for example, the cylindrical article 3 in the second column in FIG. 3 is taken out.

In the above embodiment, the three transfer mechanisms 14A to 14C are provided on the movable frame 13, but it is needless to say that the present invention is not limited to this.

Further, the gripping heads 19 need not necessarily be arranged in a line, and the gripping heads 19 may be, for example, grip type heads according to the shape or the like of the tubular article 3. Thus, the removing means for removing the tubular article 3 from the gripping head 19 may have an appropriate configuration.

[Effects of the Invention] As described above, in the present invention, a plurality of sets of gripping heads are provided, and one of the sets of gripping heads is located at the loading position, and the other set of gripping heads is located at the unloading position. Since the holding of the tubular article can be released at the carry-out position at the same time as the holding of the tubular article, the effect that the processing capacity of the anchor can be increased as compared with the related art can be obtained. Furthermore, in the present invention, the tubular article is taken out of the box in a plurality of times, but at this time, since the box is inclined, the tubular article remaining in the box is inclined by its own weight. Will be stacked underneath the box. Therefore, it is possible to prevent the tubular article remaining in the box from falling down in the box and becoming unremovable.
