Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a labeler that applies labels to both the front and back sides of the outer periphery of a container.

A labeler that attaches labels to the front and back of containers uses two disks, each equipped with a label attaching mechanism, that are placed adjacent to each other and rotated in opposite directions, and the container is flipped from one disk to the other and handed over. One is a system that attaches labels to both sides, and the other is a rotating disk with two label attaching mechanisms, and a mechanism that inverts each container on the disk. A method of attaching a label has been known so far.

The former type of labeler advances the containers in an S-shape, so when the labeler is inserted into the conveyor line, the conveyor line is not only at a different level at the labeler, but also requires the operator to monitor and operate two labels. The mechanisms are located on opposite sides of the conveyor.

As a result, a single worker must pass under a continuous conveyor for monitoring and operation, which is dangerous and difficult work, so two workers are required, reducing labor costs. Also, because the space for pasting is limited to within half the circumference of the disk, it is not possible to set up a finishing process for each disk.The finishing process is at the end, so "the label pasted on the first disk is There is also the disadvantage that the label is rubbed by the next disc and misaligned.In the latter type of labeler, the label pasting mechanism is located on the same side of the conveyor line, so only one operator is required because the conveyor line does not have different levels. ``Since a container reversing mechanism must be incorporated into each of the many container holding parts on the disk, the price is extremely high, which is a drawback.

Furthermore, if the shapes and dimensions of the containers in both cases differ, the labeling mechanism must be readjusted, but in the past, readjustment work has not always been easy. The purpose of the present invention is to provide a labeler that does not have the above-mentioned disadvantages, and the gist thereof is to Two star wheels each equipped with a label pasting machine including a process are arranged at a distance from each other, and a rotating body is provided between the two to transfer the two containers while inverting them.

The apparatus of the present invention will be explained based on embodiments shown in the drawings.

As shown in Figures 1 and 2, a conveyor 6 is provided along the trailing edge of the aircraft, and its inlet 30 and outlet at both ends are connected to the conveyor line.The inlet of the conveyor 6 and the container B are spaced apart. A screw 2 is provided, and a guide 4 that is used as the inlet star wheel 3 is provided next to the screw 2. It rotates in synchronization with the inlet star wheel 3 to move the container B to the star wheel 8.
A first star wheel wealth to be received from the first star wheel wealth and a first guide 25 along it are provided. A rotating body 7 equipped with six container holders 22 is provided at the center. Second star wheel 8 to second guide 2 on the exit side, exit star wheel 10 to same guide fee 1, first star wheel 3 on the entrance side, first guide 2
Entrance star wheel 3 has the same shape and size as the guide 4 and is located in a symmetrical position with respect to the front and rear vertical planes that include the center of the rotor dragon.The center of the rotor 7 is located between the first and second star wheels. It is located on the perpendicular bisector of the line connecting the mouse centers of the first and second star wheels 5 and 8. The container receiving pitch circles of the first and second star wheels 5 and 8 and the container holding pitch circle of the rotating body 7 are in point contact with each other. The first and second star wheels 5 and 8 rotate in the same direction and at the same speed. and a second workbench 233, with two tortoises located on the back and forth slide adjustment mechanism; and on each workbench 23, 24, a label pasting mechanism including a glue rubber roll 12, a glue roll 13, a glue collar 14, and a suction drum turtle 5'' are installed. A stamping drum is installed.

Normally, the stamping machine 18 and the back label hopper wing 9 are placed on the first workbench 23, and the front label hopper is placed on the second workbench 24.
Put 2G on it. First and second workbenches 23 for these members
9 The arrangement on the two turtles is exactly the same. Two finishing rolls are provided on the first and second guides 28 and 28 for finishing the attached label. The control panel group 18 is installed on the front upper surface on the entrance side of the aircraft group. As shown in Figure 3, the rotating body hole includes a vertical shaft 3Q and four hollow shafts rotatably fitted to the vertical shaft 3Q via bearings.

A cylindrical body 32 provided with a cam groove S to the top of a vertical shaft 30 is keyed. A gear 4 turtle is keyed to the bottom of the hollow track 40, and a flange-shaped upper plate 42 and lower plate 43 are attached to the upper end and the middle. The supporting core 45 of the pedestal 44 on which the container B is placed via a bearing is located at a position that is in contact with the container holder pitch circle of the first and second star wheels 5 and 8 of the lower plate turtle 3 and divides the pitch circle into six equal parts. A gear 46 is keyed to the lower end of the supporting bag turtle 5, which is rotatably supported by a bearing. Upper plate 42 corresponding to the pedestal umbrella 4
The shaft 48 is passed through the sleeve umbrella 7 at the position shown in FIG. Attach the cam roll 3 base 35 to the bag that protrudes horizontally in the diametrical direction.One cam roll 3 stitches and cam groove 3 kawakohame, and the other cam roll 3 mouse sleeve breast milk are fixed in the vertical direction of the guide plate g. Therefore, when the hollow sacrificial turtle Q rotates, the shaft turtle rotates and moves up and down along the cam groove 3.The part above the upper plate 42 is a cover 39 attached to the upper end of the vertical shaft 3. A sector gear 58 that engages with a gear 46 fixed to the lower end of the support shaft 45 of the pedestal 44 is rotatably fixed to the lower plate 43.

A cam roll 51 is shaft-fixed to the sector gear 50, and the cam roll 51 is fitted into a cam register 53 of a cam plate 52 fixed to the body 1. As shown in FIG. 4, the pedestal 44 moves along with the lower plate 43 from the position where it receives the container B from the first star wheel 5 to the position where it passes the container B to the second star wheel 8.
When it revolves at 80 degrees, the cam roll 61 attached to the lower surface of the sector gear 501, which is also rotatably attached to the lower plate, rotates along the fixed cam groove 53, so that the part relative to the downward slope mother 3 rotates. (approximately 300 in the figure)
Rotate. Since the sector gear 601 is meshed with the gear 46 which is integrated with the pedestal 44, when the sector gear 58 is partially rotated, the pedestal 44 is reversed by 180 degrees with respect to the downward slope 43. Therefore, the container B moves from the first starwheel to the second starwheel via the rotating body without changing its direction. Although not shown, the gear 41 at the lower end of the hollow shaft 48! The hollow shaft 4 is meshed with a gear that rotates the first and second star wheels 5 and 8 so that the pedestal turtle 4 is synchronized with the container receiving portion of the first and second star wheels 5 and 8.
Rotate 0 in the opposite direction.

These rotational drives and operations of the label pasting mechanism, such as pulling out labels from the label hopper, stamping, and pasting, are all interlocked and controlled by a circuit provided in the control panel 11.
Next, the operation of the labeler of the present invention will be explained.

Containers B sent from a series of conveyor lines to the inlet side of the conveyor 6 proceed along the path shown by the arrow in FIG. If an abnormality occurs in
Safety switch 38 is activated to stop operation. The container 8 is guided by the inlet starwheel 3 and the guide 4 and passes to the first starwheel 5 which rotates synchronously. While being guided by the first star wheel 5 and the first guide 25, a back label is pasted on the back side of the container B facing outward by the label pasting machine on the first workbench 23. Finishing roll 2 on No. 25 finishes the attached back label. The container 8 revolves while sliding on the upper surface of the fuselage turtle while being pushed by the first star wheel 5 and reaches the engagement part with the rotating body 7, but as shown in FIG. The top is fuselage 1
Since the top surface of the container B is the same as that of the first star wheel 5 and is synchronized with the first star wheel 5, the container B is smoothly transferred to the pedestal 44.

As soon as the container B is placed on the pedestal 44 and begins to revolve around the vertical axis 30, the upper cam groove 31 presses down the container holder 22 to hold down the container B and prevent slippage between the container 8 and the pedestal 44. do. Before the container B reaches the engagement portion between the rotating body 7 and the second star wheel 8, the cam groove 31 raises the container holder 22 to release the container B, but in the meantime, the lower cam hawk 53 rotates the sector gear 50 by a predetermined angle, and the gear 46
The pedestal 44 is rotated by 180 degrees. As a result, the container B is passed from the rotor 7 to the second starwheel 8 in the same state as when it was passed from the first starwheel 5 to the rotating body 7, and the container B is transferred from the second starwheel 8 to the outer surface. to face. The pasting mechanism on the second workbench 24 pastes the front label on the surface of the container B that revolves while being guided by the second star wheel 8 and the second guide 28, and then the finishing roll 21 on the second guide 28 pastes the front label. Finish the attached front label.

After that, the container B is passed over the exit star wheel 101,
They are guided by a guide 9 and get onto the conveyor 6. Container B with labels pasted on both sides is sent from the outlet of conveyor 6 to the next process by a conveyor line. As mentioned above, the labeler of the present invention can not only be inserted into the conveyor line of a series of packaging processes, but also the label pasting mechanism is located in the front half of the machine, so operation and monitoring are very easy. be.

Therefore, not only one worker is required, but also other machines can be used at the same time to save labor. Since the applied label is immediately finished by the finishing roll 21,
There is no possibility that the initially applied label will come into contact with the second star wheel 8 and be displaced. Although the number of pedestals 44 for the rotating body shown in the embodiment is six, it is possible to have fewer or more pedestals than this. However, since the number of holders is related to the price, it is desirable to have six or less in order to keep the price low. The suction drum 16 is installed on the stands 23 and 24, and acts in the front and rear directions with respect to the center of the star wheels 5 and 8. By moving the work platforms 23, 24, the first and second guides 25, 28 can be easily replaced.Also, the suction drum 15 can be easily adjusted for a new container using only the handle. Therefore, the labeler of the present invention is capable of processing containers of various shapes and sizes, and adjustments accompanying changes in containers can be made reliably and easily in a short period of time.
