Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an article stacking device for stacking and storing articles in a magazine.

[Problem that the invention attempts to solve]

In automatic machines such as packaging machines, articles that are continuously manufactured or provided are temporarily stored in a magazine,
It may be desirable to supply each magazine to the next process. In this case, in a machine that stores articles in a magazine, that is, an article accumulation device, it is necessary to attach and remove the magazine from the machine.
If the machine is stopped each time, the operating rate of the machine will decrease, which is undesirable.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an article stacking device that allows articles to be stacked without stopping the machine when a magazine is installed or removed.

[Means for solving problems]

The present invention, which was developed to achieve the above object, stores articles in a stacked manner in a magazine that has an article storage space and an article stopper attached to the lower end of the magazine that allows articles to be pushed in but prevents articles from falling out. The article stacking device includes: a fixed hopper fixedly provided above the article supply position; a magazine receiving holder on which a magazine is removably mounted above the fixed hopper; The stationary hopper has an article passageway leading from the lower end to the magazine above, and the fixed hopper has an article passageway leading from the lower end to the magazine above, and the lower end of the article passageway allows the articles to be pushed into the fixed hopper. The drive mechanism for the push-up bar includes a first drive means for reciprocating the push-up bar in a predetermined small stroke, and a second drive means for reciprocating the push-up bar in a large stroke. The gist of the present invention is an article stacking device characterized by having two driving means.

[Effect]

According to the article stacking device configured as described above, the push-up rod normally performs a reciprocating motion with a small stroke, and feeds the articles being sent to the article supply position into the fixed hopper one after another. The fed articles are prevented from falling off by the article stopper at the lower end of the fixed hopper, are stacked in the fixed hopper, and are further fed into the magazine above the fixed hopper. Once a predetermined amount of articles have been accumulated in the stationary hopper and the magazine above it, the push-up bar performs a long upstroke to feed the articles in the stationary hopper into the magazine and empty the stationary hopper. Thereafter, the push-up rod starts reciprocating with a short stroke again, and articles are fed into the stationary hopper one after another, but until the stationary hopper is full, the magazine is removed and a new empty magazine is installed. In this way, magazines can be installed and removed without stopping the machine.

〔Example〕

Hereinafter, preferred embodiments of the present invention shown in the drawings will be described.

FIG. 1 is a schematic cross-sectional view showing an article accumulating device 1 according to a preferred embodiment of the present invention, and FIG. This is for stacking and storing shaped articles 2 in a magazine 3. Article accumulating device 1
has a support plate 5 that supports the article 2 to be stored in the magazine, and on the support plate 5 there is a pusher 6 for moving the article 2 on the support plate, as shown in FIG. Stopper 7 to stop at a predetermined position
will be provided. Hereinafter, the position of the article 2 regulated by the stopper 7 will be referred to as the article supply position. A fixed hopper 10 fixed to the machine frame 9 is provided above the article supply position. A magazine receiving holder 12 is provided on the upper surface of the machine frame 9, and the magazine 3 is removably mounted on the magazine receiving holder 12. The fixed hopper 10 has an article passage 13 in which articles 2 can be stored in a stacked state and delivered to an upper magazine 3, and the magazine 3 is connected to the article passage 1 of the fixed hopper 10.
It has an article storage space 14 that matches 3. At the lower end of the fixed hopper 10, there is an article stopper 17 that can pivot about a fulcrum 16, a fixing pin 18 that prevents the tip of the article stopper 17 from pivoting downward, and a direction in which the article stopper 17 is normally pressed against the fixing pin 18. A coil spring 19 is provided which applies a force to the article stopper 17. The tip of this article stopper 17 slightly protrudes into the article passage 13, and prevents the article 2 in the passage from falling downward, but when the article 2 is pushed up from below, it pivots upward and allows the article to pass. This allows for Note that the article stopper 17 is not limited to a rotatable one as in the illustrated embodiment, and can stop the article 2 from below.
It may be of a type that, when pushed up, recedes to the left and right to allow articles to pass through. An article stopper 21 similar to the article stopper 17 is also provided at the lower end of the magazine 3.

Below the article supply position, a push-up rod 23 for pushing up the article 2 at the article supply position into the fixed hopper 10 and a drive mechanism 25 for the push-up rod 23 are provided. The drive mechanism 25 includes a guide rod 26 fixed to the machine frame 9, a slide block 27 slidably held by the guide rod 26, and an air cylinder 2 fixed to the slide block 27.
8. It has a guide rod 29 etc. which is slidably held on the slide block 27, and the push-up rod 23 is fixed to the piston rod of the air cylinder 28 and a plate 30 fixed to the tip of the guide rod 29. Further, a drive means, such as a cam drive means (not shown), for reciprocating the slide block 27 along the guide rod 26 with a small stroke is connected to the slide block 27 via a connecting rod 32. This drive means includes a first drive means that reciprocates the push-up bar 23 in a small stroke so that the push-up bar 23 pushes up the article 2 on the support plate 5 into the fixed hopper 10 to a position where it is held by the article stopper 17. Configure. The air cylinder 28 constitutes a second driving means for reciprocating the push-up bar 23 with a large stroke so that the push-up bar 23 pushes up the articles 2 accumulated in the fixed hopper 10 into the magazine 3.

Next, the operation of the article stacking device having the above configuration will be explained. Normally, the air cylinder 28 is stopped, and the slide block 27 is reciprocated with a small stroke by the first driving means, so that the push-up rod 23 is reciprocated with a small stroke. When the push-up rod 23 is retracted from the upper surface of the support plate 5, the articles 2 to be accumulated are sent to the article supply position by the pusher 6. Next, the push-up rod 23 rises to push up the article 2 into the fixed hopper 10 and hold it in the article stopper 17. Thereafter, by similar operations, the articles 2 are fed one after another into the fixed hopper 10, and after filling the fixed hopper 10, the articles 2 enter the magazine 3 above it. When the uppermost article 2 in the magazine 3 reaches a predetermined height (this state can be determined using a counter), the air cylinder 28 is activated to push up the push-up rod 23 with a large stroke. By this operation, all the articles 2 in the fixed hopper 10 are fed into the magazine 3. After that, the air cylinder 28 is retracted again to lower the push-up rod 23,
By reciprocating the slide block 27 with a small stroke by the first driving means, the articles 2 are fed into the fixed hopper 10 one after another. While the articles 2 are being fed into the fixed hopper 10 (until the fixed hopper 10 is full), the magazine 3 is removed and an empty magazine is installed. It is thus possible to change the magazine 3 without stopping the machine, ie while continuously feeding the articles 2 into the fixed hopper 10.

[Effect of idea]

As explained above, according to the article stacking device of the present invention, while articles are being supplied one after another to a fixed hopper, the magazine above it can be replaced, and the machine does not have to stop when replacing the magazine. There is no need for this, and the operating rate of the machine can be improved.
