Description

DETAILED DESCRIPTION OF THE INVENTION FIGS. 1 and 2 show a conventional labeler, in which a gripper roll 1 is supported by a bearing 3 on a base 2, and is fixed to a gripper shaft 4 and a coaxial shaft 4 by a driving means (not shown). A rotary table 5, a sponge pad portion 6 integral with the table 5, a cam 8 rotatably supported by the gripper shaft 4 via a bearing 7, and fixed to the base 2 separately from the gripper shaft 4. an arm 10 that connects the fixed shaft 9 and the cam 8 and stops the cam 8 from rotating; In this structure, when a plurality of labels 13 are attached to the top and bottom of the bottle 12 at the same time (multi-point attachment), the interval between the upper and lower labels that can be attached is limited to 101 has the disadvantage of being restricted.

In the figure, 14 is a picker, 15 is a glue roll, 16 is a label box, 17 is a star wheel, and 18 is a bottle mounting table.

The present invention was proposed in order to eliminate the above-mentioned conventional drawbacks, and includes a plurality of upper and lower label gripping claw opening/closing cams fixed to a fixed shaft, and a cam that engages with the cams to move around the fixed shaft. A device 1 for simultaneously pasting a plurality of labels on a bottle at the top and bottom, comprising a rotary body for attaching a plurality of upper and lower label gripping claws that is supported so as to rotate; It is an object of the present invention to provide a label transport device characterized in that two bodies are connected to each other by a connecting member.

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 3 and 4, reference numeral 19 is a bearing fixed to the base;
A vertical gripper shaft 20 is fixed to the bearing 19 .

Reference numeral 21 denotes a rotary table which is rotatably held on the gripper shaft 20 and is driven by means not shown.

A power transmission shaft 22 is vertically fitted into the rotary table 21, and a sponge pad 23 is attached thereto.

A bearing 24 is fitted and fixed to the gripper shaft 20, and a cam 25 for opening and closing the label gripping claws is fixed thereto.

Reference numeral 26 denotes a bearing that is fitted and fixed to the gripper shaft 20 with a spacer 27 interposed between it and the bearing 24, and a rotary table 28 is rotatably held therein. The upper end of the rotary table 21 is fitted into the rotary table 21.

A bearing 29 is fixed to the bearing 26, and a sponge pad cam 30 and a label gripping claw opening/closing cam 31 are fixed to the upper and lower sides of the bearing.

A shaft 32 is slidably held on the rotary table 28, and a sponge pad 33 is fixed thereto.

A bracket 34 is fixed to the shaft 32, and a cam follower 35 that engages with the sponge pad cam 30 is rotatably supported.

36 is a spring fitted on the shaft 32 between the rotary table 28 and the bracket 34 and presses the cam follower 35 against the cam 30; 37 is a power transmission shaft fitted on the rotary table 28.

Reference numeral 38 denotes a rotary table on which a bearing 39 # is rotatably held, into which the gripper shaft 201 is fitted and fixed, and the power transmission shaft 37
The upper part of the rotary table 38, the rotary table 28, and the rotary table 21 are integrally connected.

Reference numeral 40 denotes a bearing fixed to the bearing 39, to which a cam 41 for a bottle neck gripper is fixed, and a cam follower 42 is engaged with the cam 41.

Reference numeral 43 denotes a bearing fixed to a bearing 39 at the upper part of the rotary table 38. A bottle neck gripper support lever cam 44 is fixed to the lower side, and a bottle neck gripper cam 45 is fixed to the upper side. A cam roll 46 is engaged with the cam 45, and a cam follower 47 is engaged with the cam 45, respectively.

A bottle neck gripper support lever 49 is rotatably held on a shaft 48 fixed to the rotary table 38.
The cam roll 46 is rotatably held on a shaft 50 fixed to the shaft 50 .

Reference numeral 51 denotes a pawl lever rotatably held on the power transmission shaft 221, to which a pawl 52 is fixed and a cam follower 53 that engages with the cam 25 is rotatably held.

54 is wound around the power transmission shaft 22, and the coaxial shaft 221
This is a torsion spring whose both ends are hung on the provided pin 55 and the pawl lever 51, respectively.

Reference numeral 56 denotes a pawl lever rotatably held on the power transmission shaft 371, to which a pawl 57 is fixed, and a cam follower 58 that engages with the cam 31 is rotatably held.

59 is a torsion spring that is wound around the power transmission shaft 37 and has both ends hooked to a pin 60 provided on the same shaft 37 and the pawl lever 56J, and 61 is a rotation handle of the gripper shaft 20.

A bottle neck gripper 62 for rotatably holding the cam follower 42 and a bottle neck gripper 63 for rotatably holding the cam follower 47 are rotatably supported on the shaft 50, respectively.

Further, 64 is a spring provided between the bottle neck grippers 62 and 63, a is the bottle, L1 is a shoulder label, and L2 is a body label.

Next, the effect will be explained.

When power is transmitted to the rotary table 21 by a drive source (not shown), as the table 21 rotates, the power is transmitted to the rotary tables 28 and 38 via the power transmission shafts 22 and 37. 38 rotates around the gripper shaft 20.

Therefore, the cams 25 and 3 fixed to the gripper shaft 20
When the cam followers 53 and 58 rotate around the cam follower 1 while engaging with each other, the claws 52 and 57 open and close via the claw levers 51 and 56, thereby performing a labeling action.

As explained above in detail 1, the present invention has a cam for opening and closing the label gripping claw fixed to one fixed shaft, and a plurality of upper and lower label grippers that are engaged with the cam and supported to rotate around the fixed shaft. Since the rotary bodies for attaching the claws are connected to each other by a connecting member, there is no need to provide an arm or the like from the outside of the rotary element to hold the cam as in the past, so it is possible to make the labeling intervals closer together. This makes it possible to significantly improve applicability to labeling.

Note that the present invention can be applied to labels.
