Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for inspecting the holding force of a carrier used in a bottling or canning system that can be used for a wide variety of products.

(Prior Art) Conventionally, there have been no examples of a method and apparatus for automatically inspecting the holding force of a carrier that stores a single container or a plurality of containers such as bottles and cans.

For equipment or systems designed to be able to be used for a wide variety of containers with different dimensions, when using a carrier for storing a single container or multiple containers such as bottles or cans, always check its holding power and check for defects. It was necessary to detect and remove good or damaged products.

However, as mentioned above, in the past, there was no tool that could automatically perform these inspections, so it was necessary to manually insert and pull out each carrier one by one. The actual situation was that inspections were being carried out.

Therefore, the work is complicated, requires a lot of work time, is inefficient, and is not compatible with the various systems described above.

(Problems to be Solved by the Invention) As described above, in the past, it was necessary to rely on humans to inspect the holding force of members that hold containers such as bottles and cans, which was inefficient. The problem was that this was a bottleneck for automation.

The present invention has been developed in view of these points, and it is an object of the present invention to provide a device that can automatically test the holding force of the container.

(Means for Solving the Problems) Therefore, the present invention provides an apparatus for inspecting the holding force of a container, which includes an insertion rod that is inserted into or pulled out from a holding hole of a container holding part, and an insertion rod that is inserted through an elastic body. The first component is that it is equipped with an insertion rod support member to support, a means for moving the support member, and a pressure sensor that detects the force applied to the insertion rod. The second component is that it is equipped with an insertion rod that can be inserted into or pulled out from the container, a means for moving the insertion rod, and a pressure sensor that detects the load applied to the container holding part. It is intended as a solution to this problem.

(Function) When an insertion rod having the same shape as the container is inserted into or pulled out of the holding portion of the holding member of the container, the insertion rod receives resistance from the holding portion. This resistance force is detected by a pressure sensor and automatically compared with standard pressure using various calculation formulas. As a result of the inspection, if it is found that the holding member is defective, it is removed and replaced with a non-defective holding member.

(Example) First, prior to a detailed explanation of the present invention, a holding member for bottles, cans, etc., which is an object to be inspected according to the present invention, will be explained.

FIGS. 5 to 8 show a holder centered on the holding member,
1 in the figure is a flexible material with a high coefficient of friction such as synthetic resin, rubber, or composite material, with a cutout hole 1b formed in the center for holding the container a. This flexible holding member has bellows 1a that are radially divided into a plurality of pieces.

2 is an adapter that can be used as is or can be replaced, which sets the holding force of container A according to the characteristics such as material, size, shape, etc. It consists of a perforated board. Reference numeral 3 denotes a holding frame for the holding member 1, and the holding member 1 is assembled together with the adapter 2 and bolts 4 or the like.

The above holding member 1, adapter 2, and holding frame 3 constitute a holder 5, and this holder 5 has a function of holding a container a such as a bottle or a can, and has a self-centering function.

Note that the holding member 1 can be formed into any material, plate thickness, number of divisions, and shape depending on the size, shape, amount of M, strength, material, etc. of the container a to which it is applied.
It is necessary to have sufficient holding force to hold M. In the illustrated example, the bellows 1 is divided radially into 12 pieces.
Those with a are shown. Notch 61b in the center
Of course, it is formed smaller than the outer diameter d of the container a.

In FIGS. 6 and 7, 6 indicates a carrier, and a plate 9.10 is connected between the left and right side plates 7.8 by welding or the like.
It is considered to be a one-piece structure. The side plates 7 and 8 are formed with a plurality of grooves 11 (three stages in the illustrated example) that protrude outward along the longitudinal direction, and the grooves 11 support the holder 5 in the horizontal direction and are detachable. It becomes. This groove 1
A plurality of holders 5 (six in this example) can be attached to the same stage of holder 1 . Further, the number of stages of the holder 5 is arbitrarily determined depending on the type of container a to which it is applied.

Note that this can be handled by exchanging the holder 5 for a different type of container a, but there is no need to change the dimensions of the carrier 6 (length l, width W, height h).

In FIG. 7, the container a is inserted into the cutout hole 1b of the holding member 1 from below the holder 5b, and is held in the state shown in FIG. 8. The holding force for holding the container a at this time can be arbitrarily set depending on the outer diameter d of the container a, the amount of bending of the holding member 1, and the length X of the straight portion. Therefore, holding member 1
The holding force can be set depending on the hole diameter of the adapter 2 paired with the adapter 2.

Furthermore, even when the container a is reversed by 180 degrees from the state shown in FIG. 8, the container a is held in the same manner by the holding member 1.

Next, a holding force testing device which is an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a carrier 6 on which two holders 5, each consisting of an upper holder 5a and a lower holder 5b, are attached, is placed on a pedestal 12, and an insertion rod 13 having a similar shape to six test containers a is placed on the pedestal 12. A state in which the two are inserted into the notch hole 1b of the holder 5 at the same time is shown.

A concave hole 14 concentric with the insertion rod 13 is formed in the upper end surface of the insertion rod 13, as shown in FIG. 2, and a flange 19 is formed protruding from the periphery thereof. A pressure sensor 15 is housed in the recessed hole 14 at the top of the insertion rod 13, and a compression spring 18 is installed between the top plate 16 and head 17 of the pressure sensor 15. Further, the flange portion 19
A compression spring 20 is also installed between the flange 19 and the head 17, and a compression spring 23 is installed between the collar 19 and the flange 22 of the detection cylinder 21. is designed to act upward. The detection cylinder 21 is fixed to the heft 17.

The head 17 is movable up and down along a guide 24 fixed to the pedestal 12 by a lifting device (not shown). 2
5 indicates a signal outlet of the pressure sensor 15.

By the way, in the above configuration, the following cases can be considered when the tip of the insertion rod 13 is inserted into or pulled out from the holding member 1.

(a) When the upper and lower holders 5a, 5b are not inserted at all into the holding members 1. (b) When the case is inserted only into either the holding member 1 of the upper stage holder 5a or the holding member 1 of the lower stage holder 5b.

(C) When all of the holding members 1 of the upper and lower holders 5a and 5b are inserted. (d), upper/lower holder 5a,
When pulling out the insertion rod inserted into both holding members 1 of 5b.

(e) When the insertion rod is pulled out after being inserted into only one of the holding members 1 of the upper and lower holders 5a and 5b.

However, it goes without saying that the number of states will be different if the holding member 1 has a single stage or three or more stages.

Now, considering the above case and considering the force that the insertion rod 13 receives from the holding member 1, in FIG. 2, the insertion rod 13 is placed between the upper and lower holders 5a.

When inserting into each holding member 1 of 5b at the same time, the insertion rod 13
The FH1 insertion rod 13
When the weight of the body is W and the reaction force due to the spring 18.20°23 is Fs, the force Fa applied to the pressure sensor 15 when the insertion rod 13 is not yet inserted into the holding member 1 is Fa=
It becomes Fs-W. When the insertion rod 13 is inserted into the holding member 1 of the upper holder 5a, the force Fb applied to the pressure sensor 15 becomes Fb=Fs-W+FH+ (the state shown by the solid line in FIG. 6). Furthermore, when the insertion rod 13 descends and is inserted into the holding member 1 of the lower holder 5b, the force Fc applied to the pressure sensor 15 is F c =F s -W+FH+
+FHt. On the other hand, when pulling out the insertion rod 13, the force Fd received by both the upper and lower holding members 1 is Fd=F
The force Fe received only from the upper holding member 1 on s-W-F TII -F lb is pe=Fs W FH+. In this case, the holding member 1 is in the state shown by the two-dot chain line.

In the above relational expression, Fs and W are always almost constant, so the force F applied to the pressure sensor 15 corresponding to each of the above states of insertion or withdrawal of the insertion rod 13 is measured and compared. Depending on the situation, the holding force of each holding member 1 can be detected individually or for a plurality of holding members 1 at the same time.

As a result of this detection of the holding force, the holding members 1 whose holding force is insufficient are removed from the side plates 7 and 8 of the carrier 6 for each holding member 1 fixed to each adapter 2 with the insertion rod 13 pulled out. Furthermore, it is also possible to automatically replace and mount a good holding member 1.

Note that as the pressure sensor 15, any one of an electric type, a pneumatic type, and a mechanical type can be used.

FIG. 3 shows another embodiment, in which the compression springs 18 and 19 are removed from the embodiment shown in FIG. By the compression spring 34 loaded between the lower flange 33 of 32,
It is constantly pressed upward with the force of Fs.

If the force that the insertion rod 13 receives when it comes into contact with the holding member 1 is FH1, the weight of the insertion rod 13 is Wl, and the reaction force by the spring 34 is Fs, then the force F applied to the pressure sensor 15 is F=Fs-W.
+FH, resulting in the same relational expression as in the previous embodiment.

FIG. 4 shows an embodiment in which the load applied to the carrier 49 is detected. In this example, the carrier 49 with the holders 5 mounted in two stages is placed on a stand 54, and a plurality of insertion rods 13 are mounted on the carrier 49.
This shows the state where both are inserted at the same time. The head 50 is the insertion rod 13
It has a built-in mechanism (not shown) that moves it up and down. guide 51

3 is between the intermediate flange of the insertion rod 13 and the base 54, and the compression spring 57 is the base! ? 5 and the lower end flange of the insertion rod 13, select suitable ones for both, and insert the pressure sensor 56.
The load applied to the a is set so that it is always in a constant direction and at a required level.

When the insertion rod 13 is inserted into or pulled out from the carrier 49,
The forces F1 and F2 applied to the pressure sensors 56 and 58 can be detected, respectively, and the holding forces of each holding member 1 can be compared and calculated in the same way as in the embodiment described above. In this case, the pressure sensors 56 and 58 can also be electrical, pneumatic, or mechanical.

In the above embodiments, it is generally ideal that the holding force FM generated between the holding member 1 and the insertion rod 13 is approximately equal to the holding force when the insertion rod 13 is inserted and the holding force when the insertion rod 13 is pulled out. be. However, depending on the state of damage to the holding member 1, they will not be equal or will differ greatly.

If the device according to the present invention is used for inspection, as described above, the holding force when the insertion rod 13 is inserted into the holding member 1 and the holding force when it is pulled out are respectively detected, and the holding force is This allows the holding force of No. 1 to be detected more precisely.

It goes without saying that for these inspections, the insertion rod may be inserted in a plurality of steps corresponding to the number of stages in which the holder 5 is installed.

The present invention does not stop at simply inspecting the holding force of the holding member of the container, but also involves removing defective holding members and automatically replacing them using an unillustrated unloading and automatic replacement device, etc. in conjunction with these inspection devices. It is possible.

(Effects of the Invention) As described above in detail, according to the present invention, it is possible to automatically test the holding force of a container such as a bottle or can by a holding member, and furthermore, it is possible to automatically test the holding force of a container such as a bottle or a can, and furthermore, it is possible to automatically test the holding force of a container such as a bottle or a can.
