Description

[Detailed description of the invention] This invention relates to a binding machine with a press, and in particular, includes a floating table arranged parallel to the main table with a string position in between, and the part of the object to be bound placed on the main table. The present invention also relates to a binding machine with a press capable of compressing a portion of an object placed on a floating table.

Conventionally, in this type of binding machine, in order to compress the part of the object to be bound on the floating table, in addition to an auxiliary compression plate that is placed on the floating table and moves up and down, a guide device for the auxiliary compression plate and an interlocking mechanism with the main compression plate are used. Therefore, the structure thereof is complicated and the device becomes large-scale.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a binding machine with a press that is capable of compressing the portion of objects to be bound on a floating table with an extremely simple and compact structure.

Distantly related to the above object, the binding machine with press according to the present invention is characterized in that it is equipped with a compression plate that moves up and down on the main table, an auxiliary plate that can protrude toward the floating table, and a drive device that moves the auxiliary plate forward and backward. As the driving device, a cylinder device, preferably an air cylinder, is used.

Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1 and 2 show the entirety of the tying machine according to the present invention. A fixed main table 3 is placed, a movable table 4 is placed side by side on the same horizontal plane as the main table 3, and a string hook is located between them.

The floating table 4 is suspended from a support rod which is pivoted to the rotating shaft of the arm 2.

The main table 3 and the floating table 4 constitute an article placement table.

5 is guard.

A vertically movable compression plate 6 is provided above the main table 3, and the compression plate 6 is mounted under a cylinder device 8 supported by a column 7 and is thereby moved vertically.

9 is a piston rod of the cylinder device 8, and guide bars 9' are provided on both sides thereof.

As shown in FIGS. 3 to 6, this binding machine with a press includes an auxiliary plate 10 provided inside the compression plate 6 so as to be able to move forward and backward,
Furthermore, a cylinder device 11 as a drive device for moving the auxiliary plate 10 is attached to the compression plate 6.

This auxiliary plate can suitably project through the opening in the compression plate to the side of the floating table 4 and parallel to the compression surface of the compression plate (lower surface of the bottom plate).

In the illustrated embodiment, the lower surface of the auxiliary plate 10 is the floor plate 1 of the compression plate 6.
It is placed on top of the compressed surface by a thickness of 2, but is approximately at the same level.

The cylinder device 11 is preferably an air cylinder, but a hydraulic type is also possible.

In the illustrated example, the auxiliary plate 10 is connected to the tip of the rod 14 of the drive device via a mounting plate 13 fixed thereon.

Note that the width dimension of the auxiliary plate 10 may be a partial length of the longitudinal length of the compression plate 6 as shown in FIGS. 3 and 5, but as shown in FIG. They may be the same length.

Further, as shown in the figure, at least one corner 15 of the front edge of the auxiliary plate 10 is preferably beveled or rounded, thereby facilitating escape from the wrapped string.

Note that 20 is a stopper for stopping the objects to be bound at the binding position.

During operation, with the auxiliary plate 10 protruding (advanced), the compression plate 6
When the objects to be bound A are placed in the binding position straddling the main table 3 and the floating table 4, the compression plate 6 is lowered by the operation of the cylinder device 8, and the objects A are placed on the main table 3. The part of the object to be bound is compressed, and at the same time, the part of the object to be bound on the floating table 4 is also compressed by the protruding auxiliary plate 10.

Note that the two-dot chain line in FIG. 5 and FIG. 3 show the protruding state of the auxiliary plate.

When the compression plate 6 is lowered to a predetermined position and stopped, the arm 2 of the strap hanger rotates, and the strap hanger winds the string S in that position, and attaches the cord to the object A together with the auxiliary plate 10 as shown in FIG. Wrap it around.

Next, the knot forming mechanism 1 is operated to tie the knots, and during or after the knot is tied, the cylinder device 11 is operated to cause the auxiliary plate 10 to retreat and escape, and is housed inside the compression plate 6.

Then, the compression plate 6 is raised by the operation of the cylinder device 8 and returns to its original position, and the auxiliary plate 10 is projected again to return to the initial standby state.

In addition, a cylinder device 1 for moving the auxiliary plate 10 forward and backward as appropriate.
1 is operated by an appropriate control system including limit switches, photocells, and other devices.

This binding machine with a press is particularly suitable for compressing and binding thin materials and for binding flexible materials such as newspapers.

According to the present invention, the portion of the object to be bound on the floating table can be compressed using an extremely simple and compact device.

Therefore, with a simple configuration, it is possible to compress both sides of the string that is hung around the object to be tied, and the string can be wound smoothly. This can sometimes prevent the objects to be bound from bending.
