Container handle assembly {Apparatus for assembling a container handle}

The present invention relates to a device for assembling a handle to a container such as a plastic bottle and a method for assembling the same, and more particularly, by pushing the handle into a handle mounting space on the side of a plastic bottle and assembling the handle, primarily by lifting the handle to the handle mounting space. Secondarily, by pulling the elastic piece to fix the handle at that position, and thirdly, by pulling the handle with appropriate force to identify poor fixation, the assembly defect rate of plastic bottles can be significantly reduced. It relates to a container handle assembly device that enables

In particular, the present invention avoids the non-contact method conventionally used to distinguish fixation defects of the handle and uses a method of distinguishing fixation defects by pulling the handle with an appropriate force, thereby significantly reducing the assembly defect rate of plastic bottles compared to the prior art. It can be done.

In general, polyethyleneterephthalate (PET) (hereinafter referred to as 'PET') containers, which are easy to manufacture and recyclable, are widely used as synthetic resin containers.

Recently, a container equipped with a handle has been developed so that a PET container with a large capacity can be conveniently used when transporting or taking out the contents in a stored state.

In this way, the handle mounted on the PET container is difficult to mold at the same time as the container is molded due to the nature of the PET container, so it is separately manufactured from PET material, etc. as disclosed in Japanese Patent Laid-Open No. Then, when the PET container is biaxially stretched blow-molded, it is mounted on the container by a method of integrally combining the PET container with the container.

That is, when the handle is manufactured to have sufficient rigidity and durability, and then the container is blow-molded in a state where it is fixed to the blowing mold for manufacturing the container, a part of the handle is coupled while the container is expanded, thereby manufacturing a container with a handle. there will be

However, in the case of the method of blowing molding after fixing the handle to the blowing mold, once the combined handle is difficult to separate from containers made of other materials, there is a problem in that resource recycling is difficult and disassembly cost is high.

In order to solve this problem, in Patent Application No. 2019-113425, a handle is configured as shown in FIGS. 2 to 6.

Figure 5 is an enlarged view of only the handle, showing a state before being fixed to the plastic bottle body by the handle fixing means, Figure 6 is an enlarged view of only the handle, showing a state fixed to the plastic bottle body by the handle fixing means It's a drawing

This is a structure in which the handle 9 is simply assembled after blowing molding of the plastic bottle body P, and the plastic bottle body P made of synthetic resin has a support groove R1, which is a space for mounting the handle 9, on one side, The handle 9 mounted on the support groove R1 includes a gripper 94 for gripping by hand, an upper extension part 92 connected inwardly from the upper end of the gripper 94, and the gripper 94. A lower extension part 93 connected inwardly from the lower end of the support 94, an elastic piece 91 integrally connected in the vertical direction to the inner end of the lower extension part 93, and the upper and lower parts It consists of coupling protrusions 95a and 95b protruding outward from the extensions 92 and 93, respectively.

The tip of the elastic piece 91 is configured to slide on the surface of the upper extension part 92, and the inclined jaw 96 and the locking jaw 97 respectively protrude on the surface of the upper extension part 92, An end accommodating part 98 of the elastic piece is provided between the inclined jaw 96 and the locking jaw 97.

Figure 2 is a view showing a state before the handle is supplied to the plastic bottle body in the handle supply means of the present invention device, Figure 3 is a view showing a state before the handle is fixed to the plastic bottle body in the handle fixing means of the present invention device,

When the handle 9 is coupled to the plastic bottle body P, as shown in FIG. 2, the elastic piece 91 of the handle 9 is bent inward and the distance between the coupling protrusions 95a and 95b is reduced. Since it is in a state of being, it can be coupled by being inserted into the coupling grooves 12a and 12b of the plastic bottle body P. (See FIG. 2)

In this state, when the tip of the elastic piece 91 is pushed outward to exceed the inclined jaw 96, the tip of the elastic piece 91 'clicks' and is caught on the locking jaw 97 to accommodate the tip of the elastic piece. It is located in part 98,

At this time, the elastic piece 91 of the handle 9 spreads outward and the gap between the coupling protrusions 95a and 95b widens, so that the coupling protrusions 95a and 95b form a coupling groove of the plastic bottle body P ( It is hooked on R2) and firmly fixed.

This handle structure and fastening method are equally applied in the present invention,

In the conventional container handle assembling device, the method of separating the fixing failure after fixing the handle is different.

A rotary table 107 provided with a plurality of container receiving grooves 108 at regular intervals at the outer end so that it can rotate by 1 click while accommodating the plastic bottle body P supplied from the outside;

A handle supply means 101 for supplying the plastic bottle bodies P supplied from the outside to the container receiving groove 108 one by one.

Container aligning means for accurately arranging the plastic bottle body (P) in the container receiving groove 108 for the next process, located where the plastic bottle body (P) supplied from the handle supply means 101 is rotated by 1 click ( 102) and,

The plastic bottle body (P) supplied from the container aligning means 102 is located at a place rotated by 1 click, and the handles 109 supplied from the outside are picked up one by one and the handle mounting space, that is, the support groove of the plastic bottle body (P) (R1) a handle supply means 103 to be located,

The plastic bottle body (P) supplied from the handle supply means 103 is located where the plastic bottle body (P) is rotated by 1 click, and the elastic piece 91 of the handle 109 is pulled to engage the coupling protrusions 95a and 95b of the handle. A handle fixing means 104 to be caught and fixed in the coupling groove R2 of the body P,

A handle fixing state checking means 105 located at a place where the plastic bottle body P supplied from the handle fixing means 104 is rotated by 1 click and distinguishing a poor fixing state of the handle 105,

Finally, it consists of a container discharge means 106 for supplying the plastic bottle body P out of the rotary table 107,

In the conventional container handle assembling device, since the handle fixed state confirmation means 105 is a non-contact confirmation method using an infrared sensor, etc., there is a problem in that it is not possible to completely check whether the handle is actually detachable or not, only checking whether the handle exists and whether there is a gap.

Therefore, even if the handle fixing state checking means 105 is used, assembly defects of the plastic bottle still exist, and there is a problem in that the value as a product decreases due to a high assembly defect rate.

An object of the present invention is to assemble the handle by pushing it into the handle mounting space on the side of the plastic bottle, primarily pick up the handle and supply it to the handle mounting space, and secondarily pull the elastic piece so that the handle is fixed in that position. And, thirdly, the purpose is to significantly reduce the assembly defect rate of the plastic bottle by pulling the handle with an appropriate force and distinguishing the poor fixation state.

In other words, by avoiding the non-contact method conventionally used to distinguish fixation defects of the handle and using a method of distinguishing fixation defects by pulling the handle with an appropriate force, the assembly defect rate of plastic bottles can be significantly reduced compared to the prior art. It has its purpose.

The above object is, in the container handle assembly device for coupling the handle to the support groove (R1) of the plastic bottle body (P),

A rotary table provided with a plurality of container receiving grooves at regular intervals at the outer end so that it can rotate by 1 click while accommodating the plastic bottle body (P) supplied from the outside;

a handle supply means for supplying plastic bottle bodies (P) supplied from the outside to the container receiving groove one by one;

a handle supply means positioned after the handle supply means and for picking up handles supplied from the outside one by one and positioning them in the support groove (R1) of the plastic bottle body (P);

a handle fixing means located after the handle supply means and pulling the elastic piece of the handle so that the engaging protrusions of the handle are hooked and fixed to the engaging groove (R2) of the plastic bottle body (P);

a handle fixing state checking means positioned after the handle fixing means and distinguishing a poor fixing state of the handle;

It can be achieved by providing a container discharge means for supplying the finished plastic bottle body (P) out of the rotary table, located after the handle fixing state confirmation means.

The means for checking the fixed state of the handle includes: first, a spout gripper for firmly supporting the spout of the plastic bottle body (P); The operation of inserting into the handle and then moving backward is repeated, and the two are positioned facing each other. an arm that operates so that it is closed; elastic protrusions provided on the inside of the front ends of the arms with elasticity and inclined inwardly toward the gripper of the handle (P); an arm support for supporting the arms and changing the spacing thereof; a rod connected to the arm support; It consists of a cylinder for moving the rod forward and backward.

Initially, the rod and the arm support are moved backward by the cylinder, so that the elastic protrusions provided inside the tips of the arms are located outside the handle, and the intervals between the arms are separated.

Since the cylinder operates and the rod and arm support advance, the two facing arms advance into the handle of the plastic bottle with a gap between them,

After that, since the distance between the arms is reduced by the arm support, the distance between the elastic protrusions provided at the inner ends of the arms becomes narrower than the width of the handle gripper.

Afterwards, the cylinder operates and the rod and arm support move backward, so the two facing arms move backward out of the plastic bottle handle with the gap closed.

At this time, since the interval between the elastic protrusions is narrower than the width of the handle gripper, and the elastic protrusions have elasticity and are inclined inward,

When the arms move backward, the elastic protrusion is configured to move backward while overcoming the handle gripper along the inclined surface.

When the elastic protrusion goes over the handle holder along the inclined surface and moves backward, a pulling force acts on the handle holder, so that the handle is separated from the plastic bottle body P when the handle is not properly fixed.

After the elastic protrusion moves backward along the inclined surface over the handle gripper, the distance between the arms widens as in the initial state,

In the beginning, the main lamp gripper descends to support the plastic bottle body (P), and after the elastic projection moves backward along the inclined surface over the handle gripper, the spout gripper rises to support the plastic bottle body (P). is configured to be released.

In addition, since the arm is rotatably coupled to the axis of rotation of the arm support, it may be configured to rotate inward when the gap should be narrowed and rotate outward when returning to the original position.

The elastic protrusion may be made of an elastic material such as rubber, or may include a separate means for applying elastic restoring force to the inside of the arms.

When the handle is placed in the support groove (R1) of the plastic bottle body (P) by the handle supply means, the elastic piece of the handle is bent inward and the gap between the coupling protrusions is placed in a contracted state, in this state When the tip of the elastic piece is pushed outward beyond the inclined jaw, the end of the elastic piece is caught on the locking jaw and positioned in the end receiving portion of the elastic piece. Therefore, the coupling protrusions are firmly fixed by being caught in the coupling groove (R2) of the plastic bottle body (P).

In addition, before fixing the handle or after checking the fixed state of the handle, a leak test means for checking whether the container is damaged may be provided.

The handle supply means includes, first, a spout gripper for firmly supporting the spout of the plastic bottle body P, a tongs for picking up the handle, a rod connected to the tongs, and moving the rod forward to move the handle to the plastic bottle. It consists of a cylinder to be located in the support groove (R1) of the body (P).

The handle fixing means first includes a handle part support for firmly supporting the plastic bottle body (P), and when moving into the handle and rotating, the elastic piece of the handle is pushed so that the coupling protrusions of the handle are coupled to the plastic bottle body (P) in the coupling groove. A lever to be caught on (R2), a crankshaft coupled at right angles to one end of the lever, a cylinder, a rod moving forward and backward by the cylinder, and a rotational movement of the crankshaft It consists of a crank connected between the rod and the crankshaft to convert the

According to the present invention, the handle is pushed into the handle mounting space on the side of the plastic bottle and assembled, but first, the handle is picked up and supplied to the handle mounting space, and secondarily, the elastic piece is pulled to fix the handle at that position. , Thirdly, by pulling the handle with an appropriate force to distinguish the poor fixing state, there is an effect of significantly reducing the assembly defect rate of the plastic bottle.

In other words, by avoiding the non-contact method conventionally used to distinguish fixation defects of the handle and using a method of distinguishing fixation defects by pulling the handle with an appropriate force, the effect of significantly reducing the assembly defect rate of plastic bottles compared to the prior art. there will be

11 is a view showing a state in which a plastic bottle is fixed by first lowering the spout gripper in the handle fixing state checking means, which is a main part of the present invention, and FIG. 13 is a view showing a state in which the dog's arms advance into the plastic bottle handle with a gap therebetween, and FIG. 13 is a view showing a state in which the arms advanced into the handle are closed in the handle fixing state checking means, which is a key part of the present invention. 14 is a view showing a state in which the two facing arms move backwards out of the plastic bottle handle with the gap closed in the handle fixing state checking means, which is the main part of the present invention. , Figure 16 is a view showing a state in which the arms moved backward out of the handle are spaced apart, and FIG. 16 is a view showing that the spout gripper is raised and the turntable is rotatable in the handle fixing state checking means, which is the main part of the present invention, 17 is another embodiment of the handle fixing state checking means, which is a view showing that the arm is rotatable on the arm support so that the distance between the ends of the arms is adjusted. This is a drawing showing the state viewed from the front.

Viewed from here, the handle fixation check means 5 includes, first, a spout gripper 54 for firmly supporting the spout of the plastic bottle body P; After inserting into the handle 9, repeat the operation of moving backwards, and the two are positioned so that they face each other, the gap between the two is widened before moving forward into the handle and after fully moving backward, an arm 51 that operates to close the two gaps; Elastic protrusions 52 that have elasticity and are provided inside the front ends of the arms 51, and the portion of the handle P toward the gripper 94 is inclined inwardly; an arm support 53 for supporting the arms 51 and changing the distance therebetween; a rod 55 connected to the arm support 53; It consists of a cylinder 33 for moving the rod 55 forward and backward.

Initially, the rod 55 and the arm support 53 are moved backward by the cylinder 56, so that the elastic protrusions 52 provided inside the tips of the arms 51 are located outside the handle 9, and the arm 51 The interval between them is separated, and then the main lamp gripper 54 descends to firmly support the plastic bottle body P. (FIG. 11)

Afterwards, the cylinder 56 operates and the rod 55 and the arm support 53 advance, so that the two facing arms 51 advance into the plastic bottle handle with a gap between them. (FIG. 12)

Since the cylinder 56 operates and the rod 55 and the arm support 53 move backward, the two facing arms 51 move backward out of the plastic bottle handle with the gap closed.

At this time, since the interval between the elastic protrusions 52 is narrower than the width of the handle holder 94, and the elastic protrusions 52 have elasticity and are inclined inwardly,

When the arms 51 move backward, the elastic protrusion 52 moves backward while riding over the handle holder 94 along the inclined surface. (FIG. 14)

At this time, the handle holder 94 is pulled with considerable force, and if the handle 9 is in a poor state of fixation, the handle 9 will be separated from the plastic bottle body P, so it is easy to distinguish plastic bottles with poor assembly. be able to do

Then, the distance between the arms 51 is widened as in the initial state by the arm support 53. (FIG. 15)

Since the spout gripper 54 rises and the support state of the plastic bottle body P is released, the handle fixation check means 5 returns to its original position and the rotary table 7 becomes rotatable. (FIG. 16 )

On the other hand, Figures 17 and 18 are another embodiment of the means for checking the fixed state of the handle, since the arm 51 is rotatably coupled to the rotational shaft 57 of the arm support 53, it rotates inward when the gap needs to be narrowed. And, when returning to the original position, it is configured to rotate outward.

The cylinder is preferably composed of a pneumatic cylinder,

Since the elastic protrusion 52 has to move backward while overcoming the gripper 94 of the handle 9 on its inclined surface, it itself is made of an elastic material such as rubber, or the elastic restoring force acts on the arms 51 inward. You will be able to provide the means to become.

The elastic restoring force and the inclination of the elastic protrusion 52 may be arbitrarily determined according to the required coupling degree of the handle.

In addition, after assembling the handle, a leak test means may be provided after the step of the handle fixation check means 5 to check whether the container is damaged or not.

In the means for checking the fixed state of the handle according to the present invention, the non-contact method conventionally used to distinguish fixing defects is avoided, and the method of pulling the handle with an appropriate force to distinguish fixing defects is used, thereby reducing the assembly defect rate of plastic bottles in the conventional way. It has the effect of reducing significantly compared to .

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations fall within the scope of the claims of the present invention.
