DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article supply apparatus, and more particularly to an article supply apparatus capable of safely sending easily damaged articles or the like to a predetermined position without applying excessive pressure.

[0002]

2. Description of the Related Art As an apparatus for supplying articles to a predetermined position,
It is known to use a conveying / pressing device such as a conveyor or an air cylinder. These known techniques are generally suitable as devices for supplying items that are rigid and difficult to damage.

[0003]

However, if the article is easily damaged or easily deformed, if the article is forcibly pushed and supplied using a conveyor, frictional scratches may occur on the bottom of the article due to slippage. Further, when an article is pushed in using an air cylinder, there is a disadvantage that the article is crushed or deformed depending on the kind and quantity of the supplied article. Therefore, none of the devices is effective as a normal supply means for a soft article or the like.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a method for irrespective of the amount of an article to be supplied, and to an article which is easily damaged or crushed by pressure without being damaged by a constant pressing force. The object of the present invention is to provide a device capable of supplying a driven member that is slidably suspended on a horizontal support shaft and slides the driven member. And a driven member supported by a support rod disposed in parallel with the support shaft and capable of reciprocating along the support rod, wherein the driven member is located at a predetermined position on one side of the driven member. The driven member has a magnet body attached thereto, and the other side of the driven member is provided with a pushing member which is in contact with the supplied object and is capable of pressing and conveying the supplied object in the sliding direction of the driving member. It is characterized by. Further, at a predetermined position around the magnet body, an impact absorbing member having one end fixed to the driven member and the other end as a resilient portion is connected to the driven member and the driven member at the separated position by connecting the other end to the magnet body. It is disposed so as to protrude outward from the surface.

By arranging the shock absorbing member as described above, the shock force generated when the driven member and the driven member are connected by the magnetic force of the magnet body and the abrupt reaction force at the time of disconnection are absorbed, and the operating state of the apparatus is reduced. To keep it smooth.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a front view of a main part of an embodiment of an article supply device of the present invention, and FIG. 2 is a perspective view of the embodiment.

A driven member 2 slidably suspended on horizontal support shafts 1 and 1 having both ends fixed to a frame (not shown) comprises an air cylinder for reciprocating sliding in the direction of arrow B. The drive unit 3 is connected to a drive unit 3 ′. In addition, the supporting rods 4, 4 are provided below the supporting shafts 1, 1.
A driven member 5 which is reciprocally movable along the longitudinal direction is supported on the supporting rods 4, 4. Further, a magnet body 6 which can be attracted to the driven member 2 is mounted at a predetermined position on one side of the driven member 5, and the driven member 2 approaches and comes into contact with the driven member 5 so that the magnet body 6 Both are connected by the magnetic force of. Further, on the other side (the bottom side in this embodiment) of the driven member 5, there is provided a pushing member 7 which contacts and pushes the article A to be fed, and the pushing member 7 feeds a soft synthetic resin container. The article A is extended to a position where it is arranged on the hanging bar 9 and is on standby.

Next, the operation of the above embodiment will be described. As the driving device 3 is driven, the driven member 2 and the magnet 6
Since the driven member 5 connected in the step (5) moves forward in conjunction therewith, the pushing member 7 attached to the driven member 5 is also advanced in the moving direction of the driving device 3.

[0009] Further, since the unspecified and large number of supplied parts A arranged in advance on the hanging rods 9 can be brought into contact with the pushing member 7, the pushing member 7 further advances while pushing the supplied article A. Moving. When the article to be supplied A in the front row reaches a position where the article to be supplied A collides with the rear end of the article to be supplied A which has been supplied in advance by the previous driving operation of the driving device 3, the advancement of the pushing member 7 is hindered and stops. On the other hand, the driven member 2 further advances with the driving of the driving device 3, so that the magnet body 6 mounted on the driven member 5 has a reverse direction larger than the magnetic force maintaining the connection with the driven member 2. At this point, the driven member 2 and the driven member 5 connected to the driven member 2 are separated by the magnet member 6 because the magnetic force cannot resist the forward force of the driving device 3 at this point. Therefore,
Regardless of the remaining amount of the article A supplied in advance, the pressing force applied to the article A depends on the predetermined magnetic force of the magnet body 6 and does not exceed it. Is maintained.

Next, the pushing member 7 which has once been separated from the driven member 2 and has stopped moving is reciprocated by the driven member 2 and the driven member 5 coming into contact again with the retreat driving of the driving device 3. At the same time, it retreats and returns from the supplied article A to its original position. Thereafter, the same operation is repeated.

The provision of the shock absorbing members around the magnet body 6 (both sides in the present embodiment) reduces the impact force generated by the rapid attraction / separation action of the magnet body 6. Then, the pressing force transmitted to the supplied article A can be made to act gently.

[0012]

As described above, according to the present invention,
Since the pushing member that presses and conveys the article to be supplied connects the driven member equipped with the pushing member and the driving device via the magnet body, the pushing force that is higher than the magnetic force of the magnet body is not applied to the article to be supplied. . Therefore, even the supplied article which is easily damaged can be pushed and supplied without difficulty.

[0013] Further, even if the article to be supplied is in an oversupply state, it cannot be forcedly pushed beyond a certain pressure, so that the apparatus can be provided as an economical apparatus having a long service life.
