Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for binding flexible articles such as newspaper bundles, in particular, flexible articles such as newspaper bundles that do not bend even when the binding material is tightened. The present invention relates to a binding device for binding in a state.

[Prior Art] Among the binding devices for binding flexible objects formed by stacking a small number of newspapers, a binding device for binding the flexible objects in a state in which they do not bend even when the binding material is tightened is disclosed in Japanese Patent Publication No. Those described in 50-30520, JP-B-51-1199, JP-B-55-39778, and JP-B-55-43975 are known.

These publicly known examples are, in each case, a restricting member that enters and exits the binding material loop to restrict the binding material winding width, a guide member that guides the restricting member when entering and exiting, and a drive that moves the restricting member in and out. It is equipped with means and
Other than the device described in the -39778 publication, in the other three known examples, that is, the devices described in Japanese Patent Publication No. 50-30520, Japanese Patent Publication 51-1199, and Japanese Patent Publication No. 55-43975, the regulating member and the guide member rotate. To form a regulation width that matches the width of the object to be bound, and also has a mechanism for aligning both sides of the object to be bound with the position of the restriction member.
The device described in the publication 5 is a mechanism provided with drive means for the above-described rotation.

[Problems to be Solved by the Invention] In all of these known examples, the binding member is wound only by inserting a restricting member that restricts the tightening width of the binding member into the binding material loop. There is. Therefore, in bundling such as newspapers that are bundled in advance after being wrapped with a sheet material, when the binding material is wound up, the sheet material may be drawn toward the regulation member side along with the movement of the binding material and may be wrapped around the regulation member. Therefore, there is a disadvantage that the operation of retracting the regulation member from the binding material loop after tightening is not smoothly performed.

On the other hand, each of the binding material winding regulation mechanisms shown in the above-mentioned publicly known examples is a mechanism for actuating a plurality of regulation members by one drive means via a link or an arm member, which is relatively complicated. The mechanism is prone to malfunctions such as failures and requires frequent maintenance, and the relatively complex mechanism occupies a relatively large installation area (portion) and is a binding material that is a main component of the binding device. This is to reduce the installation area of the feeding and winding means and the binding material joining means, which makes maintenance of these means troublesome.

The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to:
Even when binding a sheet that has been wrapped in a sheet, such as a newspaper, in advance with a restraining member that has entered the loop of the binding material, the sheet width can be rolled into the regulating member even when binding with a binding material. It is an attempt to provide a binding device that does not exist.

In addition, a drive unit is provided for each restriction unit to simplify and downsize the winding tightening restriction mechanism and the binding device as a whole, thereby reducing the failure rate and performing recovery work when a failure occurs easily and quickly. In addition, it is an object of the present invention to provide a binding device that can easily perform maintenance of each unit for binding with a binding material.

[Means for Solving the Problem] In order to achieve the above object, the present invention relates to a binding device for binding a binding material around an object to be bound by binding a regulation part having a regulation rod and a regulation part. A plurality of binding material winding tightening restricting mechanisms each having a guide part for guiding in the material loop direction and a driving part for driving the restricting part are provided below the binding table, and further in the vicinity of the binding material loop and the binding material loop. At least one binding material winding regulation mechanism is provided with a packaging material lifting member that is displaceable between a standby phase that is arranged at a position where it does not interfere and sinks below the binding table and a packaging material lifting phase that appears above the binding table. A bundling device characterized by the above.

[Operation] The binding material winding tightening restriction of the binding device is performed by at least two binding material winding tightening restricting mechanisms corresponding to the width of the object to be bound,
In particular, the restriction rods are jointly operated, and each restriction unit is driven by each drive unit provided for each restriction unit.

The regulating portion moving means moves the regulating rod of the regulating portion into and out of the binding material loop, and at this time, the regulating portion is guided by the guide portion in the binding material loop, that is, in a direction substantially perpendicular to the binding material passage. , The regulation rod enters the bundling material loop and exits.

The restricting portion swinging means moves the restricting portion toward the binding material loop by the restricting portion moving means, and then swings the restricting portion so that the restricting rod is aligned with the width of the bundled object to be specified in advance.

When it swings in a fan shape, a part of these members comes out onto the conveyor belt (56) to form a predetermined width of the object to be bound (55).

Next, the operation of the embodiment of the present invention will be described in the case of binding a bundle of bound articles (55) having a width of eight folded newspapers that defines the width between the binding material winding regulation mechanisms (01) a and (01) b. To do.

The newspapers ejected from the folding device (not shown) and laminated in an appropriate thickness are packaged by the packaging device (not shown), become bundled objects (55), and reach the binding device. (551) is a packaging material for the object to be bound.

In the binding device, the binding material (51) is fed to the binding material passage (57) and the binding material guide arch (52) by the binding material feeding / fastening means (53), and at the position of the binding material joining means (54). A binding material loop (551) with which the binding material (51) overlaps is formed. (Refer to FIG. 9) The operation of the conveyor belt (56) causes the binding material loop (51
1) The width of the object to be bound (55) introduced into the inside is detected by a sensor (not shown) such as a photoelectric tube, and the binding position on the binding material passage (57) is stopped by stopping the conveyor belt (56). Stop at.

The cylinder (20) is actuated by the stop signal of the conveyor belt (56), the cylinder rod (201) is extended, and the connecting plate (2) that is fixed to the cylinder rod (201).
By moving 1) in the direction of the binding material passage (57), the entire restricting portion (1) fixed to the connecting plate (21) moves in the binding material passage (57) direction. At this time, the movable rotating body (10) fixed to the connecting plate (21) is changed to the guide rod (40
It is sliding on 1) and the block (14) is on another guide rod (40
The direction is definite because it slides on 2). By this movement, the regulation rod (13) of the regulation portion (1) projects from the rod through hole (42) of the guide portion (4) and enters into the binding material loop (511). By this movement, the roller (17) at the tip of the first link (16) of the regulating portion (1) comes to the position of the push plate (31) at the tip of the cylinder rod (301) of the cylinder (30). (See Fig.3, Fig.4, Fig.5) Cylinder (30) is activated by stop signal of cylinder (20).
And the cylinder rod (301) extends, the push plate (31) at the tip of the rod presses the roller (17), and the first link (16) and the second link (16) connected to the roller (17). The link (17) and the second arm (12) are pushed, and the movable rotating body (10) rotates about the axis of the guide rod (401) against the biasing force of the spring (18). This rotation direction is defined by a set of binding material tightening regulation mechanisms (01) a, (01).
This is the direction toward the other side of b.

Due to the rotation of the movable rotating body (10), the first arm (11) formed continuously from the movable rotating body (10) is rotated, and the regulating rod (13) continuing to the first arm (11) swings in a fan shape. Control rod (1
Due to the swinging of (3), the regulation rod guide member (41) is also centered on the axis of the guide rod (401) through the rod through hole (42) through which the regulation rod (13) slidably penetrates. As a fan-shaped swing. By this swinging, the packaging material pushing-up portion (43) continuous with the outer shell of the rod through hole (42) is raised above the conveyor belt (56) and stands up.

The operation of the cylinder (30) is stopped by the tail portion of the regulating rod guide member (41) contacting the second stopper (192). (See FIGS. 6 and 7) By raising the packaging material pushing-up portion (43), the packaging material (551) of the article to be bound (55) is pushed up from the lower outside.
(Refer to the chain double-dashed line in FIG. 2) Due to the swinging of the regulating rod (13) and the rotational upright of the packaging material pushing-up portion (43), the bound object (55) is slightly displaced from the binding position of the binding device. Even within the regulation range. Furthermore, the wrapping material pushing-up part (43) pushes up the wrapping material (551) which is loosened on both sides of the object to be bound (55), and when the tying material (51) is tightened, The excess portion is prevented from being pulled in by the binding material tightening restriction mechanism side, and for example, inconvenience such as winding around the restriction rod (13). The separation distance of one set (two) of the regulating rods (13) is the winding width of the binding material (51), and this distance changes the position of the second stopper (192) attached to the attachment slot. It can be adjusted by

Consistent with the extension operation of the cylinder rod (301) of the cylinder (30), the binding material sending / winding and tightening means (53) operates in the opposite direction to that at the time of sending, and tightens the binding material loop (51). In this winding operation, since the winding width is restricted by one set (two) of the restriction rods (13), the bound object (55) is not bent by this winding operation.

After tightening the binding material loop (51), the binding material joining means (5
4) is activated to bond and polymerize in the polymerized portion of the binding material (51), and cut the residue to complete the binding.

The cylinder (20) is actuated by the actuation completion signal of the binding material joining means (54), the cylinder rod (201) is contracted, and the connecting plate (2) fixed to the cylinder rod (201).
1), each member of the restricting portion (1) associated with the connecting plate (21) moves in a direction away from the binding material passageway (57). At this time, the regulation rod (13) retracts while being wound around the bound binding material (51) and drags the binding material (51), but the binding material (51) is the rod of the regulation rod guide member (41). It hits the outer end surface of the outer shell of the through hole (42) and hinders follow-up.

Further, the tip of the first link (16) is easily separated from the push plate (31) by the rotation of the roller (17), and is moved by the biasing force of the spring (18) by being separated from the push plate (31). The rotating body (10) rotates in a direction opposite to each other, that is, in the outward direction of the pair of binding material winding tightening restricting mechanisms (01) a, (01) b, and the restricting rod (13) continuous thereto It swings in a fan shape and falls under the conveyor belt (56), and the regulating rod (1
Along with the swing of 3), the regulating rod guide member (41) and the packaging material pushing-up portion (43) also swing outward and fall down.

The cylinder (30) similarly performs the retracting operation after an appropriate time from the start of the retracting operation of the cylinder (20). (See FIGS. 8 and 9) Next, the conveyor belt (56) is actuated, and the objects to be bound (55) that have been bound are carried out of the binding device.

[Advantage of the Invention] Therefore, according to the present invention, since the packaging material push-up member is provided in the binding material winding tightening mechanism, when the binding material is tightened, the excess portion of the packaging material of the material to be bound is wrapped with the binding material. There is an effect that it is possible to prevent inconveniences such as drawing in to the tightening regulation mechanism side and winding around the regulation rod, and smoothly exiting the regulation rod from the binding material loop.

Further, the drive unit is provided for each regulation unit to simplify and miniaturize the winding regulation mechanism and the binding device as a whole, which has the effect of reducing the frequency of occurrence of malfunctions such as failures.

In addition, there is an effect that trouble recovery and maintenance can be performed easily and quickly.
