Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for attaching anti-slip materials. More specifically, the present invention relates to a method of adding an anti-slip material made of an elastic material with flanges formed at both ends of the body to a synthetic resin molded product, and an apparatus used in this method.

Conventionally, various molded products have been manufactured using synthetic resin, but due to the inherent properties of synthetic resin, these molded products are slippery, and are particularly susceptible to handling tools such as pallets and containers for transporting cargo. When manufactured with synthetic resin, this slipperiness can cause the load to collapse, so various types of slippage 11-
Me is being considered.

Taking synthetic resin pallets for cargo transportation as an example, the surface of the pallet may be made uneven, rubber slippers may be attached to the surface of the pallet, or rubber anti-slip pads may be embedded when forming the pallet. After the pallet is molded, anti-slip treatment is carried out by fitting rubber anti-slip pieces into the openings provided on the surface of the pallet.

Among such anti-slip treatments for synthetic resin molded products, the present invention is convenient for replacing the anti-slip material. As a result of studying the method of attaching the anti-slip by fitting and the equipment used for it, we found that the anti-slip 11
- The material is attached to the hole in the synthetic resin molded product using a specific method. The present invention was completed based on the discovery that the anti-slip material can be installed more easily and efficiently.

That is, the gist of the present invention is to provide a non-slip material made of an elastic material having a circular cross-sectional shape and having flanges formed at both ends of the body, and an aperture having a shape corresponding to the shape of the non-slip material. This is a method for attaching the anti-slip material to a synthetic resin molded product, in which the non-slip material is rotated about its axis and pressed against the opening of the synthetic resin molded product, and the rotational force and pressing force cause the non-slip material to form a flange shape. A method for attaching an anti-slip material, characterized in that the anti-slip material is attached by deforming one of its parts, and a rotating shaft used in this method;
It consists of an insertion shaft that protrudes from the tip of the rotation shaft, rotates concentrically with the rotation shaft, and is movable in the axial direction of the rotation shaft, and the tip of the insertion shaft is provided with an anti-slip material. A mounting device for a non-slip material, characterized in that it is provided with a holding part that holds the material concentrically with the insertion shaft.

Next, an example of the method and apparatus of the present invention will be described in more detail with reference to the drawings.

The anti-slip material adding device of the present invention used in the method of the present invention is
It roughly consists of a drive device including a motor 3 and the like, a rotating shaft rotated by the drive device, and an insertion shaft q provided on the rotating shaft 3 with a specific structure.

In FIG. 1, the rotating shaft of the anti-slip material attachment device is connected to a motor 3, which rotates at the required number of revolutions, usually ! ;
Orpm It is arranged to rotate at a rotation speed of about -200 Orpm. The rotating shaft is supported by a support 10, and the support IO is fixed to a fixed platen/7 by a fixing bolt/2.

Further, an insertion shaft is inserted through the center of the rotating shaft. The rotation shaft q and the insertion shaft q are not directly coupled, and the insertion shaft q can move up and down inside the co-rotating shaft.

The insertion shaft q is indirectly coupled to the rotating shaft q through a sleeve q. That is, one end of the sleeve B is fixed to the insertion shaft q, and the other end is positioned to cover the outside of the rotation shaft. A slide hole 7 is provided in the sleeve B, and the stopper g is fixed to the rotating shaft by passing through the slide hole 7.

In this way, since the insertion shaft q is indirectly connected to the rotation shaft q, the following operations are performed.

The rotation of the rotating shaft 2 is transmitted from the stopper g to the sleeve 2, and rotates the insertion shaft 2 fixed to the sleeve 6.

However, since the rotating shaft q and the sleeve 6 are connected through the slide hole 7 and the stopper g, if a force is applied to push up the insertion shaft q in the axial direction, the insertion shaft will move upward. Will have to move.

In this way, the insertion shaft q rotates concentrically with the rotating shaft 7 and is movable in the axial direction of the rotating shaft.

As described above, the insertion shaft q is movably attached to the rotating shaft q, and the insertion shaft #+11 is biased toward its distal end.

This is done, for example, by pressing the sleeve 6 with a spring 73 or the like provided on the outside of the rotating shaft, and obtains the pressing force when inserting the anti-slip material/6 into a synthetic resin molded product. .

Note that the spring 3 is preferably a vertically movable spring 73 provided on the rotary punch 4 so that its pressing force can be adjusted.

A holding portion S for holding the anti-slip material/6 is provided at the tip of the insertion shaft.

The holding portion S is designed to hold the sliding member 1/6 concentrically with the insertion shaft 1.

Specifically, for example, a through hole is provided from the tip of the insertion shaft q along the axis of the insertion shaft, and a suction device as an external device is connected to the through hole.

Next, the process of inserting the anti-slip material/B into the synthetic resin molded product 27 using the apparatus described in 1-1 will be explained with reference to FIG.

As shown in the figure, Slip+L and Metou/Otsu have a structure in which flanges are formed at both ends of the body, and as shown in Figure 2 (a), the insertion is reduced in pressure with a suction device. It is sucked and held by a holding part S at the tip of the shaft q.

The degree of suction may be as long as it can be held by the anti-slip material/6, and a relatively weak suction force may be sufficient. The anti-slip material/6 is made slightly larger than one of the flanges of the anti-slip material, and is positioned within the positioning member IS that covers the tip of the insertion shaft from the side. The axial center of the insertion shaft 1 is made to substantially coincide with the axial center of the insertion shaft l. The positioning member /S can be slid upwardly along the insertion axis q by being compressed.

In this state, rotate the rotating shaft to rotate the insertion shaft and the anti-slip material.

On the other hand, synthetic resin molded product 27 to which anti-slip material /6 should be attached
A hole with a shape corresponding to the anti-slip hole is provided in the hole, and the hole is made in an appropriate manner so that it is directly under the insertion shaft q (sliding member 16). position. The opening corresponds to the non-slip material/B, that is, the non-slip material/
A is designed to fit into the shape, and it is not necessary to completely match the correspondence mentioned here; for example, in Fig. 6(c) (d
) may be an opening with a gap formed therein.

In this state, the synthetic resin molded product 27 is raised (
(The device may be lowered for installation.) Press the anti-slip material /6 into the opening of the synthetic resin molded product 27.

Anti-slip material /6 is the rotational force of insertion shaft q and spring /q
Due to the pressing force, the flanged portion on the side not held by the insertion shaft deforms and fits into the opening of the synthetic resin molded product 27, and after fitting, the deformation is restored and the installation is completed. The pressing force varies depending on the size of the anti-slip material/6, but it is usually between 9 and 1.
It is about 0Kp. (This state is shown in FIG. 2(b).) In FIG. 2(b), the spring /4' is compressed and the insertion shaft 11- is retracted into the rotating shaft.

Spring/41 is anti-slip material/6 is synthetic resin molded product 2
It serves to relieve the pressing force when pushing into the hole 7.

In addition, as the anti-slip material 6 is fitted onto the synthetic resin molded product λ7, the positioning member 15, which was covered over the anti-slip material 6, comes into contact with the synthetic resin molded product 27 and is pushed upward, causing it to slip. There is nothing that will interfere with the fitting of the stopper/B. It is preferable that the positioning member/S and the tip of the insertion shaft are replaceable depending on the size of the slide 11 and the second member/B.

This is how you use anti-slip material! The attachment to the synthetic resin molded product 27 of B is completed.

Next, we will discuss the specifics of the anti-slip material adding device using the device of the present invention.
An example will be explained using a synthetic resin molded product as a pallet for carrying cargo.

The device shown in FIG. 3 has a plurality of anti-slip material attachment devices (nine in the figure) installed on a fixed platen 7. Fixed plate/7
is fixed to the base 2/ by pillars /g provided in its squares.

A movable platen/9 is provided between the fixed platen/7 and the base 21 and is supported by a column 7g and is movable up and down. The movable platen 19 is a motor 2 provided inside the base 2/
It is fixed to a chain 20 stretched between the sprocket 1-ps on the opposite side and the sprocket 2 on the opposite side, and moves up and down according to the movement of the chain 20.

To install the anti-slip material/6, first install the synthetic resin molded product (
Place the pallet) 27 in the guide unit 9 provided on the movable platen/q. The anti-slip material/B is adsorbed and held in the holding part 5 of the mounting device/, which is in a reduced pressure state by the vacuum pump 2g. The movable platen 19 is raised by the action of the motor 2Q, the sprocket 25.2B, and the chain 2θ, and the anti-slip material 6 held in the attached device is rotated to prevent slipping on the plate in the same manner as described above. Fit the materials together.

It goes without saying that the installation positions of the plurality of mounting devices / on the fixed platen / 9 should match the positions of the openings provided in the pallet for replacing the anti-slip material. Further, the upper and lower limit detection switches 22 and 3 serve to detect the upper and lower limits of the pallet position and stop the movable platen/9.

Next, another example of the mounting device of the present invention will be explained.

The anti-slip material adding device 1 shown in FIG. 9 is configured so that a single motor 3 rotates a plurality of rotating shafts at the same time.

This is effective when a plurality of anti-slip members/6 are provided at close positions and a plurality of motors 3 cannot be attached.

In FIG. 9, gears B and B' are meshed with gear A, which is connected to motor 3 provided on support plate 33. The gears B and B' are fixed and movably provided in an arc-shaped guide hole 30 provided in a support plate 3q that is concentric with the gear A so that the gears B and B' can move along the cutting gear A that meshes with the gear A. There is.

Furthermore, gears C and C' are meshed with gears B and B', and gears c and c' maintain a constant distance from gear BXB' even if gear BX B' moves in the circumferential direction of gear A. They are connected by a connecting plate 3/ to maintain the same.

Gears a and c7 are provided on a support plate 35 so that they can be moved and fixed in an appropriate direction (usually in the direction of a line connecting gears A and C on their axes) as gears B and B' move. The shaft of the gear C is used as the rotation shaft of the sliding sealing material mounting device similar to that described above.

With such a configuration, a plurality of rotating shafts can be rotated simultaneously by one motor 3, and by appropriately changing the positions of gears BX and B', gears c and
This makes it possible to adjust the axial distance of Xc', that is, the distance between the rotation axes. This is convenient because it is easy to adjust when the mounting positions of the anti-slip materials (particularly the distance between the anti-slip materials) differ depending on the synthetic resin molded product.

What is shown in Fig. S (a) and (b) shows the position adjustment state of the gear mechanism (power part) in Fig. 4, and in Fig. S (a), the distance (P, ) between the rotation axes is If it is short, see Figure S (
b) shows the case where the distance (P2) between the rotating axes is long.

What is shown in FIG. 4 is a side view showing an example of the sliding material lB used in the method and apparatus of the present invention. Figure 4 (a
) and (b), the height is low and only one of the upper surface or the lower surface of the brim portion protrudes from the synthetic resin molded product 27. In other words, only one side of the flanged part is a non-slip material that acts as a non-slip material / B. As shown in Figure 6 (c), only one side of the flanged part of No. 6 is a synthetic resin molded product. It stood out from 27. In other words, only one of the flanges acts as a sliding member, and as shown in FIG. did. In other words, both of the flanges act as anti-slip.

In any case, since the anti-slip material /A is installed by rotating it, its cross-sectional shape is circular.

Anti-slip material/6 material is natural rubber or butadiene.
Styrol copolymer, butadiene-acryloni) IJ
Synthetic rubbers such as rubber copolymers are preferably used.

However, if the flanged part that needs to be deformed for fitting is too large for the body, it will not be able to be inserted into the opening of the synthetic resin molded product, and if it is too small, it will not be able to be inserted during use. Since it will separate and move, it needs to be made to an appropriate size. In the case of a non-slip material as shown in Figures (c) and (d), the diameter of the flange that deforms for fitting is the minimum diameter of the body of the non-slip material. N/, 47 times better/, /S~/
, T1 is approximately three times as large.

As described above, the method and apparatus of the present invention can only be achieved by attaching a rubber anti-slip material to an opening in a synthetic resin molded product by pressing it while rotating it.

In particular, it is very suitable for use as a device for automatically attaching a plurality of anti-slip materials to a synthetic resin molded product at the same time, and is extremely excellent in practical use.
