[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pressing device for a binding machine for pressing an object to be bound placed on a table from above while binding the object to be bound by a string.
[0002]
[Prior art]
For example, when a plurality of folded printed products are stacked on a table and bound with a string, a pressing device that presses the object to be bound from above during binding is used. As an example of a press apparatus conventionally used, one described in Japanese Utility Model Publication No. 55-43045 will be described with reference to the drawings.
[0003]
FIG. 4 is a perspective view showing the entire binding machine provided with a press device. 1 is a binding machine body, 2 is a support column, 3 is a fixed table attached to the lower part of the support column 2, and 4 is an upper side of the fixed table 3. A main compression plate 5, which is attached to be freely movable up and down, 5 is a compression drive device such as an air cylinder for raising and lowering the main compression plate 4.
FIGS. 5 and 6 are partial front views showing the main part of this press apparatus. In addition to what is shown in FIG. 4, 6 is a string winding arm of the binding machine body, and 7 is attached to the rotating shaft of the string winding arm 6. 8 is a loose table suspended from the support frame 7 at the same height as the fixed table 3, 9 is a guide rail attached to the back of the loose table 8, and 10 is loose along the guide rail 9. Auxiliary compression plate that can be moved up and down the table, 11 is a bracket vertically mounted on the upper surface of the auxiliary compression plate 10, 12 is movable on the upper surface of the main compression plate 4 toward the bracket 11 on the upper surface of the auxiliary compression plate 10 Reference numeral 13 denotes a cylinder device for moving the pin 12 forward and backward. A thin tip plate 18 is attached to the lower surface of the tip end of the auxiliary compression plate 10 so as to penetrate into the lower portion of the main compression plate 4.
[0004]
As shown in FIG. 5, the object A is placed so as to straddle the fixed table 3 and the loose table 8. Next, the main compression plate 4 is lowered by the compression drive device 5 to compress the object A to be bound. At this time, since the tip plate 18 is pushed down by the main compression plate 4, the auxiliary compression plate 10 is also lowered, and as shown in FIG. 6, the object A to be bound is composed of the fixed table 3 and the loose table 8 on the lower surface and the main compression on the upper surface. The plate 4 and the auxiliary compression plate 10 are sandwiched and compressed. When the string winding arm 6 is rotated in this state, the end of the arm is located at the intermediate position of the gap between the fixed table 3 and the loose table 8 and the main compression plate 4 and the auxiliary compression plate 10 in the horizontal direction in the figure. (This position is hereinafter referred to as a bundling line), so that the object to be bound A is exposed at this bundling line position in conjunction with a knot forming mechanism known by the name of a string feeding mechanism and a beak (not shown). The string S is wound around the portion and bound. However, at this time, the upper surface of the object to be bound A is still under the string to which the tip plate 18 is bound.
[0005]
In the present specification, the binding line is denoted by B, and the binding line side of each table and compression plate is referred to as the front end or the front, and the opposite side is referred to as the rear.
Next, after the pin 12 is protruded by the cylinder device 13, the compression drive device 5 is operated to raise the main compression plate 4. Since a hole 11a (not shown in FIGS. 5 and 6) is provided in the bracket 11 at a position corresponding to the pin 12, the auxiliary compression plate 10 is also lifted by the pin 12 fitted into the hole 11a. At the moment when the auxiliary compression plate 10 starts to rise, the string is stretched by its elasticity and is detached from the tip plate 18. The main compression plate 4 and the auxiliary compression plate 10 are moved up to the standby position to reach the state shown in FIG. 5, and one cycle of the bundling operation is completed.
[0006]
Although the auxiliary compression plate 10 has been described as being lowered when the front end plate 18 is pushed down by the main compression plate 4, the auxiliary compression plate 10 may be lowered by protruding the pin 12 and coupling with the bracket 11.
As is clear from the above description, as a characteristic of this binding machine, the string winding arm 6 rotates, so that the auxiliary compression plate 10 is not driven directly but is locked to the main compression plate 4 without being driven. That is to go up and down. For this purpose, the pin 12 and the tip plate 18 are provided. Since the string must pass through these portions, the pin 12 can be moved in and out using the cylinder device 13.
[0007]
FIG. 7 shows a partial cross-sectional view of the cylinder device 13 described in the Japanese Utility Model Publication No. 55-43045. In addition to what has already been described, 14 is a piston and 15 is a working fluid pipe.
Conventionally, in this type of press device, a cylinder device such as a midget cylinder is attached to and protrudes from the upper surface of the main compression plate 4, and this moves up and down in front of the operator's eyes. Although the work of placing and removing the object to be bound on it could not be carried out with peace of mind, the cylinder described in Japanese Utility Model Publication No. 55-43045 was downsized to prevent it from protruding from the main compression plate. As a result, there was no sense of danger, safety was improved, and the work was performed reliably.
[0008]
[Problems to be solved by the invention]
It is another object of the present invention to realize further improvement in workability and maintenance-free by providing a press device that can eliminate the cylinder device itself and perform the same function as before. .
[0009]
[Means for Solving the Problems]
According to the present invention, the fixing is performed from a main compression plate provided so as to be movable up and down above a fixed table attached to a lower part of a column of the binding machine body, and a support frame attached to a rotary shaft of a string winding arm of the binding machine body. In a press device of a binding machine comprising an auxiliary compression plate provided so as to be movable up and down above a loose table suspended at the same height as the table, and a compression drive device for raising and lowering the main compression plate, the is attached a guide plate extending upwardly and rearwardly from the top tip, said auxiliary compression plate tip from its upper surface front end upward obliquely downward reached above the main compression plate, pushed into the main compression plates at elevated process tip is, but fitted with a guide pin at a position away from the main compression plate in a compressed state, the tip further distal end of the lower surface of the auxiliary compression plates reaches the lower surface of the main compression plate Is a press apparatus of a binding machine, characterized in that the mounting rate.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, the auxiliary compression plate is lifted by using the guide pin. In the compressed state, the guide pin is separated from the main compression plate, so that the string can pass as it is and the guide pin does not go in and out. Is unnecessary, the structure of the main compression plate is simplified, there is no danger, and maintenance-free operation is realized.
[0011]
【Example】
An embodiment of the present invention will be described with reference to the drawings. However, the binding machine according to the present invention is the same as that shown in FIG. 4, and the main configuration of the press apparatus is the same as that shown in FIGS. Since the only difference is only the connecting / lifting mechanism of the main compression plate and the auxiliary compression plate, the following description will be focused on this portion.
[0012]
1 and 2 are partial front views showing a connecting portion of the main compression plate and the auxiliary compression plate according to the present invention. FIG. 1 shows a rising process corresponding to FIG. The descent process or compression state corresponding to is shown. FIG. 3 is a plan view of these viewed from above. In addition to the symbols used in the previous figures, 16 is a guide plate that is attached to the top end of the main compression plate 4 and rises diagonally rearward, and 17 is a slant from the top to the top end of the auxiliary compression plate 10 from slightly above. It is a guide pin attached downward. The tip plate 18 is attached to the tip of the bottom surface of the auxiliary compression plate 10 so that the tip reaches the bottom surface of the main compression plate 4 as in the prior art.
[0013]
The guide plate 16 is attached from the front end of the main compression plate 4 toward the rear at an angle of about 45 degrees, and a position corresponding to the guide pin 17 on the auxiliary compression plate side is cut away and escaped. On the other hand, the guide pin 17 is attached downward at an angle of about 45 degrees from the tip of the auxiliary compression plate 10 slightly above, and the tip reaches the upper side of the main compression plate 4 beyond the binding line. Therefore, as shown in FIG. 1, when the main compression plate 4 is raised, the tip of the guide pin 17 is pushed up, and the auxiliary compression plate 10 is also raised.
[0014]
On the contrary, when the main compression plate 4 is lowered, the guide pin 17 is separated from the main compression plate 4, but the tip plate 18 is pushed down by the main compression plate 4 as in the conventional case, so that the auxiliary compression plate 10 is also lowered.
When binding, the string wound from above the binding line is guided by the guide pin 17 and the guide plate 16 as shown by the arrow a in FIG. Then, at the moment when the main and auxiliary compression plates start to rise, they are disengaged from the tip plate 18 by the elasticity of the cord, the cord remains below as indicated by the arrow b, and the compression plate rises.
[0015]
As described above, in the present invention, the guide pin is separated from the main compression plate at the time of tying, so it is not necessary to use the cylinder device to move the guide pin in and out, and the conventional cylinder device is unnecessary. And the main compression plate is light and simple because there is no device on the upper surface, and there is no danger even if it moves up and down in front of the operator's eyes, and it is necessary to operate the cylinder device conventionally Maintenance is easy because the fluid source, the operation switching valve, the electric circuit, etc. are no longer necessary.
[0016]
