Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod-shaped material supplying device for supplying a rod-shaped material such as a cigarette or a filter plug to a supply port such as a hopper by using a tray, and more particularly, to an upright state from an intermittently transferred carrier. Inverted transfer of the tray that has been opened as it is, and the rod-shaped material in the tray is dropped and supplied to the supply port, and then the inverted tray is transferred in reverse and returned to the upright state, and then transported in the upright state. Regarding things to take out to the car.

[0002]

2. Description of the Related Art Conventionally, as this type of rod-shaped material supplying device,
For example, as disclosed in Japanese Examined Patent Publication No. 1-38471, a lift holder that vertically attaches two tray holders symmetrically between a carrier and a supply port and turns them up and down while spirally turning 180 degrees. , A first transport mechanism for horizontally loading and unloading trays from a carrier to a lower tray holder of a lift holder, and two tray holding frames which are vertically symmetrically held and intermittently inverted by 180 degrees Some include a rotary body and a second transport mechanism for horizontally loading and unloading the tray from the upper tray holder of the lift holder over the tray holding frame in the upright state of the rotary body.

In this device, both the tray holding frames of the rotating body hold an inverted tray and an upright tray, respectively, and the rotating body is reversed to drop and supply the rod-like material from the inverted tray to the supply port. While the tray is in the upright position, the empty tray that has already been supplied from the tray holding frame in the upright state is returned to the upper tray holder of the lift holder by the second transport mechanism. At the same time as moving to the lower limit position, move the next tray to the upper limit position,
After that, the next tray that has reached the upper limit position is put into the tray holding frame in the upright state by the second transport mechanism, and at the same time, the empty tray that has reached the lower limit position is carried out to the transport vehicle by the first transport mechanism, and then, The carrier shifts to a constant pitch, and the first transport mechanism carries the next corresponding tray from the carrier to the lower tray holder of the lift holder, after which the above-described operation is repeated.

[0004]

However, in such a conventional rod-shaped material supplying apparatus, the rod-shaped material is supplied to the supply port only after the carrying-in step, the swing-up step and the reversing step are carried out twice from the carrier. Since the tray cannot be supplied, the tray transfer process from the carrier to the supply port becomes long, which complicates the structure of the apparatus, increases the size of the entire apparatus, and raises the cost.

Also, after the empty tray is carried out from the rotating body to the lift holder while the rod-shaped material is being supplied from the tray, the empty tray and the next tray are swung up and down, and the next tray is moved from the lift holder to the rotating body. Since it is necessary to carry in and prepare the next tray, it takes time to complete the preparation of these next trays, and the next rod-shaped object cannot be started unless the rotating body is reversed, and the next tray is supplied. If the processing speed of the rod-shaped object is increased and the time from the start to the end of the rod-shaped object is shortened, the supply of the tray for one box is completed and then the supply of the next tray is started. Until there is a time when there is no supply, the supply becomes intermittent, and as a result, there is no choice but to slow the processing speed of the supplied bar until the speed at which the bar continues to be supplied. I can not expect the overall speedup There is a problem that.

In view of such conventional circumstances, it is an object of the present invention to shorten the tray transfer process from the carrier to the supply port and to prepare the next tray in a short time during supply.

[0007]

In order to solve the above-mentioned problems, the technical means of the present invention is to provide an actual tray reversing mechanism and an empty tray reversing mechanism so that they can swing in the same direction. It is characterized in that the tray turned over by the above is transferred from the actual tray turning mechanism to the empty tray turning mechanism directly above the supply port.

Further, it is preferable to provide an elevating mechanism between the actual tray reversing mechanism and the empty tray reversing mechanism for raising the tray reversed by the actual tray reversing mechanism in an inverted state immediately above the supply port.

[0009]

According to the above technical means of the present invention, after the tray is loaded from the carrier to the actual tray reversing mechanism by the loading mechanism,
By reversing the actual tray reversing mechanism, the reversed tray becomes an inverted state immediately above the supply port and the supply of the rod-shaped material is started.By transferring the tray being supplied to the empty tray reversing mechanism, The tray inversion mechanism returns and inverts so that the next tray can be carried in.

Further, by raising the tray being fed while the tray is being raised by the elevating mechanism, all the rod-like objects are quickly ejected from the tray to the feed port, and the empty tray can be inverted.

Move to and return to the initial state.

Next, the operation of the rod-shaped material supplying device will be described.

First, the operation of the carry-in mechanism 2 is started in the initial state, and the real tray A is moved from the top of the carrier 1 to the real tray reversing mechanism 3.
1 has been moved forward by one pitch as shown in FIGS. 1 to 3, and at the same time, the clamping trays 3e, 3e are closed and the actual tray A is loaded by the stopper 3f. Is immovably held, and the lid 3g is further closed to close the upper surface opening A1 of the actual tray A.

After that, the actual tray reversing mechanism 3 reverses and rises to bring the actual tray A into an inverted state as shown in FIG. 4, and at the end of the reverse raising, the rear side surface A6 of the actual tray A has a positioning guide for the empty tray reversing mechanism 5. It is positioned just above the supply port C by hitting 5f.

Following this, as shown in FIG.
Operation is started and the actual tray A in the inverted state is raised, and the lid 3g is opened during the upward movement, and the feed tray C is fed from within the actual tray A.
At the same time when the dropping supply of the rod-shaped objects B ... Is started, the turbulence prevention rod 3h comes into contact with the uppermost surface of the rod-shaped objects B.

The rod-shaped objects B ... which are being dropped and fed are guided, and when this rising is completed, the holding pieces 5d, 5d of the empty tray reversing mechanism 5 are closed, and at the same time, the suction cups 5h ...
The actual tray A being supplied is held immovably while being positioned immediately above the supply port C along the protruding reference guide 5g.

Then, the sandwiching piece 3 of the actual tray reversing mechanism 3
e, 3e and the stopper 3f are disengaged from the real tray A, and the real tray A being supplied is transferred from the tray holding frame 3c of the real tray reversing mechanism 3 to the tray holder 5c of the empty tray reversing mechanism 5.
Immediately after this delivery, the actual tray reversing mechanism 3 reverses and descends and returns to the lower limit position, and the loading mechanism 2 operates again to start loading the next actual tray A from the top of the carrier 1.

Immediately after the supply of the rod-shaped material B ... From the actual tray A is completed, the empty tray reversing mechanism 5 reverses and descends to return the empty tray A'to the upright state as shown in FIGS. After the reversing and descending, as shown in FIG. 7, the bottom pressing piece 5e is disengaged from the empty tray A'and the carry-out rail 6a is moved up, and immediately thereafter, the holding pieces 5d, 5d are opened and the suction cup 5h is opened.

Following this, the operation of the carry-out mechanism 6 is started, and the empty tray A'is carried out from the tray holder 5c of the empty tray reversing mechanism 5 onto the empty carrier 1 ', and from within this tray holder 5c. At the same time when the empty tray A'is taken out, the empty tray reversing mechanism 5 reverses and rises and stands by, and the actual tray reversing mechanism 3 reverses and rises a little later, and thereafter the above-described operation is repeated.

On the other hand, FIG. 8 to FIG. 10 show another embodiment, in which the empty tray reversing mechanism 5'reverse central axis is located substantially directly above the actual tray reversing mechanism 3'reversing central axis 3a '. 5a 'are arranged in parallel, and an empty tray reversing mechanism 5'is swingably provided in the same direction along the outside of the swing path of the real tray reversing mechanism 3', and the real tray reversing mechanism 3'reverses and rises. An elevating mechanism 4'is separately arranged so as to face the empty tray reversing mechanism 5'reversed and raised from the position, and the inverted state of the actual tray reversing mechanism 3'reverses and rises directly above the supply port C. The actual tray A is moved from the tray holding frame 3c 'to the lifting mechanism 4'.
When the actual tray A is moved up and raised, and when the actual tray A is moved up to a position where it does not interfere with the swing of the actual tray inversion mechanism 3 ', the actual tray inversion mechanism 3'is inverted and lowered, and the elevated lift mechanism 4'is also raised. The empty tray A'is transferred to the tray holder 5c 'of the empty tray reversing mechanism 5'and is returned to the upright state by reversing and descending.

In this case, the stopper 3 which is movable in and out of the tray holding frame 3c 'of the actual tray reversing mechanism 3'.

Clamping piece 4 which is held in contact with and separated from A5 and A5
The c'and 4c 'are connected in a freely openable and closable manner, and after the reversing and raising of the actual tray reversing mechanism 3'is completed, the cover plate 3d' is opened together with the retracted stopper 3f 'as shown in FIG. The actual tray A can be raised, and at the same time, the clamping pieces 4c ', 4c' of the elevating mechanism 4'standby at the lower limit position are closed to keep the actual tray A being supplied immovable.

After that, when the pinion 4a 'of the lifting mechanism 4'starts rotating, the rack 4b' moves up while holding the inverted actual tray A, and this actual tray A swings with the actual tray reversing mechanism 3 '. At the time when it reaches the position where it does not interfere, as shown in FIG. 12, the holding trays 5d 'and 5d' of the empty tray reversing mechanism 5'standby at the upper limit position are closed to move the empty tray A '.
Is held immovable, and then the holding piece 4 of the lifting mechanism 4'is held.

Therefore, in this embodiment, the actual tray reversing mechanism 3'and the empty tray reversing mechanism 5'are centrally arranged on one side of the supply port C, so that they are opposed to each other across the supply port C. Compared to the embodiment shown in which the actual tray reversing mechanism 3 and the empty tray reversing mechanism 5 are arranged, the whole apparatus can be made compact, and the actual tray reversing mechanism 3'and the empty tray reversing mechanism 5'are not provided. The space on one side of C can be effectively used, and by arranging the packaging machine in this space, the bar-shaped material B can be dropped and supplied directly from the actual tray A to the hopper E of the packaging machine, and the hopper E of the packaging machine can be supplied from the lower end of the supply port C. Therefore, it is not necessary to laterally install the conveyor belt D, and the cost can be reduced accordingly.

Further, this is a transporting path 1a for a transporting vehicle 1 on which an actual tray A is placed at a position facing each other with the actual tray inverting mechanism 3'and the empty tray inverting mechanism 5 'interposed therebetween.
The transporting paths 1a 'of the empty transporting vehicles 1' ... for collecting the empty trays A'are separately arranged, and the transporting vehicle 1 of this transporting path 1a is arranged.
The real tray A is loaded from the top by the loading mechanism 2 to the real tray reversing mechanism 3'waiting at the lower limit position, and the empty tray reversing mechanism 5'which has been inverted and lowered is carried out by the unloading mechanism 6 '. Carry out to 1 '.

It should be noted that, although not shown, the forward end of the conveying path 1a is curved and connected to the conveying path 1a 'so that the empty carrier 1'moves from the conveying path 1a to the conveying path 1a'. Further, as shown in FIG. 13, the real tray A is carried into the real tray reversing mechanism 3 ′ from the carrier 1 on the same conveying path 1a by the carry-in mechanism 2 and is carried out from the empty tray reversing mechanism 5 ′. It is also possible to carry out by 6 to the carrier 1'in an empty state.

In the embodiment shown above, the supply port C is arranged at a position higher than the upper surface 1b of the carrier 1 on which the tray A is placed. However, the present invention is not limited to this, and for example, the upper surface 1b of the carrier 1.
And the supply port C may be arranged at substantially the same height position.

[0042]

Since the present invention has the above-mentioned structure, it has the following advantages.

1. After loading the tray from the carrier to the actual tray reversing mechanism by the loading mechanism, by reversing this actual tray reversing mechanism, the reversed tray becomes an inverted state immediately above the supply port, and the supply of rod-shaped objects is started. By transferring the tray being supplied to the empty tray reversing mechanism, the actual tray reversing mechanism is returned and reversed so that the next tray can be carried in, so that the tray transfer process from the carrier to the supply port can be shortened. The next tray can be prepared in a short time during feeding.

Therefore, as compared with the conventional one in which the rod-like material cannot be supplied to the supply port without passing through the carrying-in process, the swivel-raising process and the reversing process twice from the carrier, only one carrying-in process and reversing process are required. Can supply a rod-shaped object to the supply port, and the structure of the device can be simplified accordingly, and the entire device can be made compact.
Moreover, the cost can be reduced, and after the empty tray is carried out from the rotating body to the lift holder while the rod-shaped material is being supplied from the tray, the empty tray and the next tray are swung up and down, and the next tray is rotated from the lift holder. Compared to the conventional one that requires carrying in the body and preparing the next tray, the actual tray reversing mechanism returns and inverts and the preparation of the next tray is completed just by loading the next tray, and the supplied rod-shaped Even if the processing speed of the product is increased and the time from the start to the end of the supply of the rod-shaped product is shortened, the rod-shaped product can be continuously supplied correspondingly, and the overall speed can be increased.

2. By raising the tray being supplied while keeping it upside down by the elevating mechanism, all the rod-shaped objects come out from the tray to the supply port quickly, and the empty tray can be inverted, so the inversion of the empty tray is fast. The cycle time can be further shortened by that much.
