Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a Shrink labeler position regulating device that regulates the position of a Shrink label after it is attached to a container.

(Prior Art) In conventional products of this kind, the shrink label is attached to a bottle by being held between nails, and then transported to a certain position where it is to be applied while being held.

(Problem that the invention attempts to solve) However, in the case of a device that moves the shrink label by holding it in its claws, the mechanism increases,
Another drawback was that the control system was complicated.

(Means for solving the problem) The present invention was devised in view of the above-mentioned points. Compressed air is blown toward the container to which the Shrink label is attached, and this air is used to This problem was solved by moving the shrink label downward so that it was received by a position regulating sponge timing belt that clamped the bottom of the container.

That is, the present invention includes a device for detecting the container on both sides of the conveyor for transporting containers to which the Shrink label is attached, and a delay device activated by this detection device to direct compressed air to the container. In addition to providing a compressed air nozzle for blowing, sponge timing belts for regulating the position of the shrink label are disposed on the left and right sides so as to clamp the bottom of the container.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

First, for convenience of explanation, the syringe labeler will be explained.

The one shown in the figure shows a 4-head intermittent linear movement type syringe labeler, in which the bottles flowing under pressure are fed into the syringe labeler by a timing screw while being spread evenly, and when the bottles are stationary. Labels are inserted into bottles and the bottles are then discharged in a subsequent operation, in what is called a single cycle in which four bottles with labels attached are discharged.

Starting from the entrance of the Schullin labeler, a pair of upper and lower screws 1 and 2 whose pitch gradually increases toward the labeler is provided, and a guide plate 3 is provided opposite to the screws 1 and 2. Below these, there is a synchronized conveyor 4 which is driven in synchronization with the transport conveyor of the present machine, which will be described later, and which supports the bottom of the bottle and feeds it to the transport conveyor of the present machine.

A pair of upper and lower screws 1 and 2 are arranged so as to correspond to the body and shoulder of the bottle.

The screws 1 and 2 arranged as described above increase the moving speed of the bottle b at the conveyor speed of the machine, and the bottles flowing in the pressed state are transferred to the timing screws 1 and 2.
This allows it to be fed into the inside of the labeler machine while spreading it out evenly.

Next, a screw 5 is provided in the discharge part of the labeler, and the pitch is gradually reduced from the labeler.
Other screws 6 are arranged correspondingly. Furthermore, a carry-out belt 7 is provided to support the bottom of the bottle and carry it out.

Next, the pair of left and right transport conveyors 8, 8' of the Schullin labeler are equipped with grippers 9, 9' at regular intervals, and the bottoms of the four bolts b are held by the grippers 9, 9', respectively. It is now possible to stop at the position.

Loading bars 10 and 10' for loading label a into bottle b are the support shafts of arms 15 and 15' connected by pins 13 and slit grooves 14 to bars 12 connected to the piston rod of cylinder 11. 16, 16', and arms 15, 16'.
Since the insertion bars 15' swing around the support shafts 16, 16', the insertion bars 10, 10' also swing together with the support shafts 16, 16'.
are arranged symmetrically, so the label a can be spread out using the fillers 17 and 17' attached to it, and in order to load the label a into the bottle b, a cylinder is moved as shown in Fig. 3. At 18, the entire link mechanism mentioned above is raised and lowered.

It goes without saying that the operating mechanism of the insertion bar 10 as described above is installed at a position where the transport conveyors 8, 8' of the machine hold the four bottles b with their grippers 9, 9' and stop at a fixed position. be.

Next, the label a supplying device will be explained based on FIG. 4.

In FIG. 4, reference numeral 19 denotes a tube-shaped film winding drum, from which the film a is drawn out by constant film feed rollers 20, 20', passed through a guide roller 21, a dancer roller 22, and guide rollers 24, 27. Static electricity generated on the film surface is removed by static electricity removing devices 28 and 28', and the film is supplied to film feed rollers 29 and 29'.

The film feed rollers 29, 29' are supported by opposing film pressers 30, 30', from which the film is fed to the cutters 31, 32.

The numeral 31 is a fixed cutter, and the numeral 32 is a movable cutter that moves back and forth with the piston rod of the cylinder 33.

Label a cut by cutters 31 and 32 is sucked from both sides by suckers 17 and 17, and the piston rods of cylinders 11 and 11' pull label a left and right to open the flat label.

The cartridges 17, 17' which have been moved back to the left and right by the cylinders 11, 11' are carried to the position of the bottle b by the cylinder 18 and placed over the bottle.

The constant film feed roller 20 and the film feed roller 29 are connected to the brake clutch 3 by a motor 36.
4, 35 to transmit the belt. Therefore, when the detection sensor 26 detects the fixed pitch marks made on the film in advance, the brake clutch 35 is activated.
When the film is removed, the drive of the film feed rollers 29, 29' is stopped, and cutting is performed by the cutters 31, 32.

Since the constant film feed rollers 20 and 20' are driven while the film is being cut, the film is fed, and the dancer roller 22 descends as shown by the solid line in the figure, and finally reaches the micro switch 23. Brake clutch 34 in contact
Remove. Therefore, the film constant feed rollers 20, 2
0' is stopped and the supply of film is stopped.

Since the brake clutch 35 is re-engaged after a certain period of time, the film feed rollers 29, 29' are operated to pull the film.

Then, the dancer roller 22 is pulled up from the illustrated position and separated from the micro switch 23, the brake clutch 34 is turned on again, and the constant film feed rollers 20, 20' are activated to feed the film.

By the above-described operation, the film is constantly fed toward the film feed rollers 29, 29' and cut at a constant pitch.

It goes without saying that the sutchers 17, 17' grip the film before the above-described cutting is performed.

Note that 25 indicates a stamp for stamping the date.
This activates the cylinder by means of a detection sensor 26 and stamps the date on the film.

The film supply device as described above is activated when the bottles conveyed by the conveyors 8, 8' of the present machine stop at a fixed position.

The present invention is a device for regulating the position of a shrink label on a bottle to which such a shrink label is attached.

That is, in FIGS. 5, 6, and 7, a driving shaft 41 and a driven shaft 42 are installed vertically on a frame in which a main plate 37 and a sub-plate 38 are connected by stud shafts 39 and 40, and a timing shaft is connected to the frame. Pulleys 43 and 44 are attached, and a sponge timing belt 45 is stretched between these pulleys. Drive shaft 41
is the motor 4 attached to the main plate 37
It is driven by a driven gear 48 that meshes with a drive gear 47 of No. 6. In addition, the sub-plate 38 has a photocell mount 49.
, and the phototube 50 is equipped with a syringe label a to detect the bottle b.
A nozzle 51 is suspended from the main plate 37, which uses a delay device (not shown) in this detection device to spray compressed air onto the shoulder of the bottle b.

The nozzles 51, 51 and the timing belts 45, 45 described above are connected to the main plate 37.
They are arranged symmetrically with respect to each other, and the bottle b can be transferred while being held between them.

There is a drive sprocket 52 on the shaft of the motor 46 for interlocking the left and right timing belts 45, 45, and the other drive shaft 41 is driven by this and a driven sprocket 53 driven via a chain 54. There is.

The apparatus as described above is supported 57 in a suspended form on a machine frame 55, and the bottles b are transferred to the position regulating apparatus by a conveyor 56.

Now, when the labeled bottle b is discharged from the syringe labeler as shown in FIGS. 1 to 4, the bottle b is subsequently brought to the position regulating device by the conveyor 56.

Then bottle b has timing belt 45, 45
However, the phototube 50 detects the bottle b, and a delay device operates to set the timing, and compressed air is sprayed from the nozzle 51 toward the bottle b.

The spraying time is controlled by a timer. Therefore, the label a is moved downward of the bottle b by this air, and the timing belt 4
5, 45 and stops.

Thus, when the timing belts 45, 45 are in a predetermined position with respect to the bottle, the position of the label is regulated thereby, and the label is attached to each bottle at a fixed position.

The bottle b whose label position has been regulated is conveyed by the timing belts 45, 45 and the conveyor 56 to the shrinking device from which it is discharged from the position regulating device. Although not shown, the vertical position of the timing belt is adjusted by setting the position of the timing belt by moving the timing pulleys 43 and 44 up and down with screws relative to the drive shaft 41 and the driven shaft 42.

(Results of the invention) As described above, the present invention uses a sponge timing belt that controls the position of the bottle, that is, a container that is held and conveyed from below, and a compressed air nozzle that blows air onto the container above the belt. Since the label is configured so that the mounting position of the label can be regulated, it has a simpler structure and is easier to manufacture than the conventional one, which is moved by holding it with claws. No damage will be caused.
