Description

[Detailed description of the invention] This invention relates to a device for dispensing items of a certain size, such as bottles and cans, one by one at each predetermined dispensing signal in a vending machine, etc. When extruding items arranged in rows sequentially from the first item in each row,
The dispensing order can be correctly regulated so that the first article in the column next to the column in which the first article was dispensed is dispensed by the next dispensing signal. An object of the present invention is to provide an article dispensing device capable of replenishing articles on one guide rail group while dispensing articles on the other guide rail group.

The details of this invention will be explained below based on the drawings.

In Fig. 1, reference numeral 1 indicates a plurality of guide rails arranged in parallel, and reference numeral 2 indicates an article receiving section provided over the entire length at the bottom of each guide rail 1, on which an article 3 is slidably placed. There is.

Reference numeral 4 denotes rotary shafts rotatably supported by appropriate bearings (not shown) at the front and rear of the guide rail 1, and a plurality of sprockets 5 are fixed to each shaft 4.

In addition, as shown in FIG. 2, three sprockets 5 are fixed to the shaft 4, and three endless chains 76 are connected to the front and rear sprockets 5, and a plurality of guide rails 1 are formed between the three endless chains 76. The columns constitute the idrail group.

In this case, four guide rails 1 are arranged between adjacent channels 76 as shown in FIG. 1, and articles 3 are arranged in three rows.

Thus, one shaft 4 is driven by a motor M.

Both ends of the horizontal frame 8 that crosses each guide rail group are fixed to the check 76, respectively.

The horizontal frames 8 are arranged so that one side is at the top and the other side is at the bottom, and the push pieces 7 of the article 3 are fixed to the front part of each frame 8.

As is clear from FIG.
Shift it by the amount and fix it to the horizontal frame 8.

In addition, a swing plate 10 rotatably supported by a shaft 9 is provided in front of the guide rail 1, and the upper end of this swing plate 10 is supported by a spring 1.
1, the limit switch LS1 is brought into contact with the limit switch LS1, and when the article 3 at the tip of the rail 1 tilts forward, the lower part of the swing plate 10 is pushed so that its upper end is separated from the limit switch LS1, and the swing plate 10 contacts the limit switch LS1. The motor M is stopped at the moment the motor is separated from the motor.

Further, near each folded portion of the outer check 76, there are limit switches LS2, LS3, which are pushed by the end of the horizontal frame 8. L
S4. Place the LS5 respectively, and install the horizontal frame 8 on the switch LS2 side.
When the shortest pushing piece 7 pushes out the last article 3 from the tip of the receiving part 2, the end of the horizontal frame 8 pushes the switch LS2, and when the switch LS2 is pushed, the motor M continues to rotate. Make it.

Further, the horizontal frame 8 on the limit switch LS3 side is located above the folded back end of the checker 76, and each push piece I is in contact with the rear part of the article 3 lined up between the rails 1 on this side. The switch LS3 is then pressed so that the motor M stops at this time.

Further, the switch LS4 is configured to be pressed at the end of the horizontal frame 8 when the pushing piece 7 of the horizontal frame 8 on this side pushes out the last article 3 on this side, and the pressed switch LS4 continues the rotation of the motor M. Then, the horizontal frame 8 of the switch L S and IIJ turns upward from the rear chain folding part, and the rail 2 on this side
When the articles 3 are already lined up between them, the motor M is stopped when the switch LS5 is pressed with each push piece 7 in contact with the rear of these articles 3.

However, even if there are no articles 3 lined up on this side, the motor M will of course be stopped by the limit switch LS5 when it reaches the position where it should come into contact with the last one of the articles 3 lined up. .

This invention has the above-mentioned configuration, and at first, predetermined articles 3 are lined up between each rail 1 between each check 76 and supported by each receiving part 2.

In this state, first limit switch LS2. Each push piece 7 provided on the horizontal frame 8 on the guide rail group on the LS5 side comes into contact with the rear part of each article 3 and stops at +LL. Make sure you feel supported.

A coin is inserted in the above state, it is sorted by a sorting machine to confirm that it is correct, and a payout signal is sent to the motor M. When the check 76 rotates and the horizontal frame 8 advances, each article 3 is pushed out. , when the leading article 3 protrudes beyond the receiving part 2 by more than +, the article 3 falls forward as shown by the chain line in FIG.

Therefore, the limit switch LS is no longer pressed by the swing plate 10, and the motor M is stopped.

Therefore, the article 3 at the head of the next row is stopped in a state where it protrudes from the receiving part 2 by approximately +.

Next, when a coin is inserted again and a payout signal is issued to the motor M, the motor M starts, advances the horizontal frame 8, pays out the next article 3, and moves the limit switch LS1 to the swing plate 1.
When 0 is removed, motor M stops.

The above operation is repeated, and the first item 3 in each column is paid out each time a coin is inserted.

In this way limit switch LS2. LS, when all the articles 3 pushed by the pushing pieces 7 of the horizontal frame 8 on the side are dispensed, the horizontal frame 8
presses the limit switch LS2, so the motor M continues to rotate even though the swing plate 10 has moved away from the limit switch LS1.

For this reason, limit switch LS3. When the horizontal frame 8 on the guide rail group on the LS4 side turns upward from the folded part at the rear of the checker 76, and the push piece 7 contacts the rear part of each article 3 placed between the rails 1 on this side, the horizontal frame 8 is limit switch L
Press S3 to stop motor M.

After that, limit switch LS3.
The articles 3 pushed by the push piece 7 of the horizontal frame 8 on the LS4 side are dispensed one by one each time a coin is inserted.

As mentioned above, limit switch LS3. When the horizontal frame 8 moves forward each time the article 3 on the LS4 side is dispensed, and the last article 3 is dispensed, the horizontal frame 8 presses the limit switch LS4, causing the rotation of the motor M to continue, causing the limit switch LS, and the horizontal frame 8 on the side. When the button 76 rotates upward from the rear folded part of the check 76 and reaches a position where the push piece 7 comes into contact with the rear of the article 3 between the rails 1 on this side, the limit switch L is activated regardless of the presence or absence of the article 3.
S5 is pushed by the horizontal frame 8 and the motor M stops.

At this time, since the horizontal frame 8 on the side not pushing the articles 3 is located below, the articles 3 can be easily supplied between the rails 1 even during operation.

Further, although the plurality of push pieces T provided on the horizontal frame 8 have different protruding amounts in the illustrated example, the protruding amounts are made equal, and instead, the positions of the tips of the receiving portions 2 of each rail 1 are shifted. has the same effect, and limit switch LS7. LS2. LS3. L
S4. The LS5 and the like may be omitted and the check 76 may be moved at a constant pitch for each payout signal.

This idea consists of arranging guide rail groups consisting of a large number of parallel guide rails in two rows in parallel as described above, and placing the push pieces 7 of the horizontal frame 8 belonging to each guide rail group between each guide rail 1. A very simple mechanism is used to dispense a large number of articles one by one at each dispensing signal, and when one horizontal frame 8 is in operation, the other horizontal frame 8 is located below the guide rail 3, so that the other horizontal frame 8 is not moved to this side. Since the articles 3 can be freely replenished, there is no need to stop selling while the articles 3 are being replenished, and this has the effect of increasing the operating efficiency of the vending machine.
