【Example】

 FIG. 1 shows an embodiment of the present invention. Three encoders for detecting rotation of a pallet, that is, a speed detection encoder SE connected to a driving mechanism LD for driving each element including a pallet of a labeler are shown. , An angle detection encoder AE and a print control encoder PE.

The speed detection encoder SE detects the rotation speed of the pallet and is used to change the timing of ink ejection by the ink jet printer according to the magnitude of the speed. When the pallet rotation speed is high, the ink ejection timing must be advanced to make the label print position blank, and when the pallet rotation speed is low, ink droplets must be delayed to print on parts other than the label. Will be done.

The detection signal of the speed detection encoder SE is given to the speed range detector SD. The velocity range detector SD discriminates whether the detection signal of the velocity detection encoder SE belongs to a predetermined number, for example, 32 velocity categories, and outputs it as velocity range data to the command signal forming device IS.

The command signal forming device IS compares the speed range data with the data indicating the rotational position of the pallet from the angle detection encoder AE, that is, the angle data, and outputs the command signal at an angle corresponding to the rotation speed of the pallet, that is, the start of printing. Output timing command.

The print start timing command is given to the control device PC of the printing device PA. In addition to this, the control device PC is supplied with print content information from the print content input device TK and a pallet rotation state signal from the print control encoder PE. As a result, the control device PC starts printing the information from the print content input device TK at the print start timing from the command signal forming device IS, and sequentially prints it according to the pallet rotation state from the print control encoder PE. Control the printing machine.

After the label is printed and displayed by the printer, the label is attached to the bottle by the labeler device.

2 to 4 show a labeler device to which the printer of the present invention is applied. This labeler device has a magazine 1 for holding stacked labels, a large number of pallets 3 provided on the outer periphery of a pallet cylinder 2 close to the magazine 1, a glue cylinder 4 for gluing the pallet 3, and A gripper cylinder 5 that contacts the pallet 3 and rotates with each other, a gripper claw 6 provided on the gripper cylinder 5, a cradle 7 that holds the label P between the claw 6, and a bottle. A bottle holder B suspended from the lower surface to form a transfer path is in contact with the gripper cylinder 5 and comprises a top holder 8 for rotating and transferring the bottle bottle B in order. Further, in the present invention, as will be described later, a projection 9 is provided at the tip of the gripper claw 6 and the pedestal 7 is made of an elastic body such as rubber or plastic.

The magazine 1 holds the labels P to be stuck on the bottle B in a stacked manner and stores them so that they can be fed out individually. A pallet cylinder 2 rotating clockwise is provided near the magazine 1. A large number of fan-shaped pallets 3 are arranged on the outer periphery of the pallet cylinder 2 at equal pitches, and are rotated clockwise in accordance with the rotation of the pallet cylinder 2.

The glue cylinder 4 is made of rubber and has a cylindrical shape. The glue cylinder 4 is provided at an appropriate position so as to come into contact with the side surface 3 a of the rotating pallet 3, and a glue surface is formed on the outer periphery of the glue cylinder 4. The adhesive is applied to the side surface 3a of the pallet 3 by rotating in contact with 3a.

Further, a gripper cylinder 5 is provided at a position appropriately separated from the center of the pallet cylinder 2, and when the pallet 3 rotates around the pallet cylinder 2, the outer periphery of the gripper cylinder 5 is the pallet 3. It comes into contact with the side surface 3a. That is, the magazine 1, the glue cylinder 4, and the gripper cylinder 5 are arranged in three separate directions so that their respective contacting positions do not interfere with the pallet 3 rotating around the pallet cylinder 2. It

The gripper cylinder 5 is provided with a plurality of gripper claws 6 on the periphery thereof, a pedestal 7 and a sponge 10 for guiding the label P near the pedestal 7.
