Abstract

PURPOSE:To prevent deformation or distortion in a mechanism by a structure wherein a slide having the U-shape with the open side downward and whose sides are slidably in contact with the sides of frame-pieces is provided with a cushioning material on the underside of the upper part and a guide which is slidable on the slide through a slit formed in the side of the slide is fixed to the side of the frame-piece. CONSTITUTION:Through a slit 24 formed in each side 21 of a slide 20 which is a U-shaped structural part with the open side downward, a guide 50 fixed to the side 13 of a frame-piece 10 is slidably in contact with the side 21 of the slide 20; with thus the guides 50 controlling the sliding motion of the slide 20 along the frame-pieces 10, it is prevented for there to be irregular alternate loads, including, for example, sideways motion, which apply to the slide 20 in directions deviating from the sliding directions of the slide 20. When the slide 20 falls to the lower dead point, a cushioning material 35 provided on the underside of the top part 22 of the slide 20 comes in contact with the top ends 53 of the guides 50 so that by reducing impacts applying to the frame- pieces 10 and the slide 20 they can be prevented from deformation or distortion.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a label applicator that continuously applies labels on a mount to an object.

2. Description of the Related Art In recent years, label applicators that attach labels on paper mounts to objects have been used for attaching price labels at mass retailers as a suitable means for continuously attaching labels to objects with simple operations. Widely used for utensils, etc.

Conventionally, in this type of label applicator, a roll of paper with labels attached at regular intervals is mounted on a drum rotatably supported within the frame of the label applicator, and is configured with, for example, pins or levers. Generally, the last end of the roll paper is pulled out from the tram by an operator's pressing operation on a handle, and a label is affixed to an object using a roll paper feeding mechanism.

Problems to be Solved by the Invention Most of the above-mentioned label applicators are manual type, and because of their ability to apply labels continuously, they are often operated repeatedly at a fairly rapid pace.

For this reason, irregular alternating loads including lateral wobbling in a direction different from the pressing direction may be applied to the drive unit such as a slide that slides when the operator presses the handle.
An abnormal shock may be applied.

However, in the above-mentioned conventional label applicator, there is a strong demand for miniaturization and weight reduction of the device, so mechanisms such as mechanisms for dispersing or reducing the alternating load, shock absorbing mechanisms, etc. are not provided in the mechanism such as the slide ( As a result, irregular alternating loads may accelerate the wear of sliding parts such as slides, abnormal impacts may cause problems such as failure of the mechanism, or the mechanism may become deformed or distorted. Ta.

The present invention solves the above problems, and prevents irregular alternating loads, including lateral wobbling, in a direction different from the sliding direction, from being applied to a slide that slides due to an operator's label pasting operation. Another object of the present invention is to provide a label applicator that can absorb abnormal impacts to the mechanism and prevent deformation and distortion of the mechanism.

Means for Solving the Problems In order to achieve the above object, the present invention disposes a buffer member on the back side of the upper surface of a substantially U-shaped slide whose side surface slidably abuts against the side surface of the frame, An elongated hole is formed in the side surface of the slide, and a guide that slidably abuts on the side surface of the slide is fixed to the side surface of the frame via the elongated hole.

Effect The present invention has the above-mentioned configuration, which prevents irregular alternating loads from being applied to the slide in a direction different from the sliding direction, including, for example, lateral wobbling, when the slide slides relative to the frame. It is possible to buffer abnormal impacts on the frame and slide, thereby preventing deformation or distortion of the mechanism.

The slide 20 is always urged upward in FIG. 1 with respect to the frame 10 by a spring 40.

Furthermore, an intermediate lever 45 having an engagement piece 46 at the tip and a substantially triangular tracing hole 47 is pivotably supported at the tips of both side surfaces 21 of the slide 20.

On the other hand, elongated holes 24 are formed in both side surfaces 21 of the slide 20, and in each of the elongated holes 24, a metal material, for example, a sintered metal material, which is slidably abutted against the side surfaces 21 of the slide 20 from the inside, is formed. The mounting base portions 51 of the guides 50 made of the above are respectively inserted. The end faces of each of these mounting base portions 51 are brought into contact with both side surfaces 13 of the frame 1o through elongated holes 24, and the guide 50 is fixed to each side surface 13 of the frame 1o with screws 54 at the contact position 20. There is.

As shown in FIG. 3, the guide 50 is in contact with the side surface 21 of the slide 20, which has a substantially U-shaped cross section, and the guide surface 52 of the guide 50 is in contact with the guide piece 25 of the slide 20.

Therefore, by utilizing the gap between the longitudinal stroke in the mounting base portion 51 of the guide 50 fixed to the frame 10 and the longitudinal stroke in the elongated hole 24 formed in the slide 20, the guide 50 becomes a guide member of the slide 20. It is intended to function as a

In addition, below the frame 10, a winding wheel 65 for winding up the mount 57 after the label 58 has been peeled off by the peeling shaft 62 is rotatable in the counterclockwise direction in FIG. 5 by a ratchet mechanism (not shown). It is attached to.

A plurality of feed pins 66 are protruded from the side surface of the take-up wheel 65 at equal intervals at positions on the same radius around the rotation axis of the take-up wheel 65. As the slide 2o and the intermediate lever 45 descend as they are pressed, the engagement piece 46 of the intermediate lever 45 engages with the feed pin 66 and pushes the feed pin 66 down, thereby moving the winding wheel 65 as shown in FIG. I'm trying to rotate it in a counterclockwise direction.

Further, on both side edges of the rotation body 67 of the winding wheel 65, there are feed claws that engage with feed holes (not shown) drilled in both side edges of the mount 57 and wind up the mount 57 as the winding wheel 65 rotates. 68 are protruded at equal intervals, and between the peeling shaft 62 of the frame 10 and the take-up wheel 65, tension is applied to the mount 57 that is transferred between the peeling shaft 62 and the winding wheel 65.
A tension roller 70 for reliably winding the mount 57 around the winding wheel 65 is rotatably installed via a shaft 75.

On the other hand, as shown in FIG. 6, this shaft 75 has a tracing pin 81 loosely inserted into the tracing hole 47 of the intermediate lever 45 in the middle thereof.
A crimp lever 80 with a crimping lever 80 is swingably attached.
A rubber pad 85 is provided at its tip to press the label 58 peeled off from the mount 57 onto the object.

The profiling pin 81 of the crimp lever 8o is inserted into the profiling hole 4 formed in the intermediate lever 45 by lowering the slide 20 and the intermediate lever 45 as the operator presses the handle 30.
7, and as the copying pin 81 descends, the crimping lever 80 swings downward in FIG. 6 about the shaft 75.

Next, the operation of the label applicator of the present invention having the above configuration will be explained.

First, when the operator presses the handle 30 from the initial state shown in FIG. 6, the slide 20 is guided by the guide 50 and descends while resisting the tension of the spring 40, and the intermediate lever 45 also descends accordingly. do.

Then, the locking piece 46 provided on the intermediate lever 45 pushes down the feed pin 66 of the take-up wheel 65 shown as A in FIG. Push down pin 81.

As shown in FIG. 7, when the handle 30 and the slide 20 descend to the vicinity of the bottom dead center, that is, by the stroke H, the locking piece 46 of the intermediate lever 45 engages the winding mechanism shown by A in FIG. The feed bin 66 of the wheel 65 is pushed down to the position B in FIG. 7, whereby the take-up wheel 65 rotates by one pitch in the direction of X in the figure and winds up the mount 27.

At this time, the label 58 attached to the mount 57 is peeled off from the mount 57 by rotating the advancing direction of the mount 57 by approximately 180 degrees at the peeling shaft 62, and the label 58 attached to the mount 57 is peeled off from the mount 57 by rotating the advancing direction of the mount 57 by approximately 180 degrees at the peeling shaft 62. is sent out to the guide 14. Further, the mount 57 after the label 58 has been peeled off passes through the tension roller 70 and is rolled up onto the winding wheel 65.

When the handle 30 and the slide 20 descend by the stroke H, the copying pin 81 is pushed down by the oblique side 48 of the copying hole 47 in parallel with the hoisting operation of the hoisting wheel 65, and the crimp lever 80 moves in the direction indicated by Y in FIG. As a result, the label 58 sent out to the guide 14 is attached to the frame 10 by the above-described operation, and the label 58 is attached to the rubber pad 85.
It is pressed and crimped onto the object to be affixed.

In addition, after the above operations are performed, the operator
When the pressure is stopped, the handle 30 and the slide slide 20 are pulled back upward from the bottom dead center in FIG. 7 by the reaction force of the spring 40, returning to the initial position in FIG. 6, and the next label 58 is pasted. It becomes ready for operation.

As described above, according to the label applicator of this embodiment, the guide 50 fixed to the side surface 13 of the frame 10 through the elongated hole 24 formed in each side surface 21 of the slide 20 is attached to the side surface of the substantially U-shaped slide 20. 21, and thereby the guide 50 guides the sliding movement of the slide 20 with respect to the frame 10. Therefore, the guide 50 guides the sliding movement of the slide 20 with respect to the frame 10. Load can be prevented from being applied to the slide 20.

Furthermore, when the slide 20 descends to the lowest dead center, the buffer member 35 provided on the back side of the upper surface 22 of the slide 20 comes into contact with the upper end 53 of the guide 50, thereby buffering the impact applied to the frame 10 and the slide 20. This can prevent these deformations and distortions from occurring.

Effects of the Invention As described above (according to the present invention, a buffer member is disposed on the back side of the upper surface of the approximately U-shaped slide whose side surface slidably contacts the side surface of the frame, and a buffer member is provided on the back side of the upper surface of the slide. In addition to forming the hole, the guide that slidably abuts on the side of the slide is fixed to the side of the frame via the elongated hole, so when the slide slides against the frame, it will move in a direction different from the direction of sliding. It can prevent irregular alternating loads, including directional, for example, lateral vibration, from being applied to the slide, and can also buffer abnormal impacts on the frame and slide, preventing deformation and distortion of the mechanism. .
