Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for putting disposable chopsticks (hereinafter simply referred to as chopsticks) into a chopstick bag, and in particular, a device that allows chopsticks to be inserted into the chopstick bag and taken out reliably and at high speed. This is what I did.

Devices for putting chopsticks into chopstick bags have conventionally existed, but these have the following drawbacks.

First, to insert chopsticks into a chopstick bag, gas is blown into the opening of the chopstick bag to open it, the tips of the chopsticks are introduced here, and the chopsticks are inserted all the way to the bottom of the bag. Even if the gas is injected into the bag, the slot may not open properly, or when inserting chopsticks into a bag and pushing it out, the next bag may be pulled out due to friction, or the chopsticks may become warped or twisted. There were times when the tips of the chopsticks would not fit into the slot in the bag. In addition, when taking out the chopstick bag in which chopsticks have been inserted, conventional devices use a separate removal device (for example, a layering device using a suction cup) after insertion is completed, and such a method does not improve work efficiency. Naturally, there was a limit. The present invention has been made to overcome these conventional drawbacks, and utilizes the following principle.

In other words, for this type of disposable chopsticks, the insertion opening of the chopstick bag is cut out diagonally or at a right angle, leaving the backing paper behind, and the original part of the chopsticks is made to protrude outward from the insertion opening. is always the case. Therefore, by skillfully utilizing this, the most advanced bag stored in the magazine is held by a locking plate that contacts the paperboard in front of the insertion opening and a locking protrusion that contacts the lower edge of the bag. , a regulating piece is formed on the rear side in the direction of movement of the chopsticks, and the flap of the locking plate is
On the front side, a gas jet nozzle attached to the insertion hole is activated to ensure that the insertion port opens, and a chopstick tip guide device installed at the rear of the chopstick travel path allows the chopsticks to close to the locking plate. The chopsticks are inserted into the insertion port through the front surface of the chopsticks bag. After reaching the bottom of the chopstick bag, the pushing action of the chopsticks releases the backboard of the insertion slot from the locking plate, allowing it to fall out of the magazine and being taken out. This prevents bags from flying out and allows for reliable bag setting, allowing continuous operation at high speed. The present invention will be specifically described below based on illustrated embodiments.

FIG. 1 shows an embodiment of the device according to the present invention, which is roughly divided into a chopstick side device 1 and a chopstick bag side device 2. First, the chopstick side device 1 will be explained based on FIGS. 1 to 4. Reference numeral 3 denotes a base, on which the travel trajectory 4 of the chopsticks A is set.

Specifically, a pair of guide side plates 5, 5' are established in parallel on the base 3, and the chopsticks A are passed between them. Next, the continuous supply device 6 for chopsticks A will be explained. First, a hopper 7 is provided above the running track 4, and as shown in FIG. will be established. This outlet 7' is provided with a leveling rotating body 8 in order to take out the chopsticks A one by one facing the same direction. The one shown in the figure is a ratchet-like rotating body, and the gap between the claw 8/ and one side plate 7' of the hopper 7 at the outlet 7/ is larger than the short diameter side of the rectangular cross section of the chopsticks A. By making it slightly wider and rotating it in the opposite direction to the direction in which the chopsticks are dropped (direction D in the figure), align the chopsticks A so that they all reach from the short diameter side to the outlet.
This allows only objects in this direction to pass through. In addition, a passage 9 having a width slightly wider than the minor axis dimension is formed between the outlet γ and the running track 4, and along this passage, the chopsticks A are dropped into the running track 4 while maintaining a constant direction. do. The chopstick continuous supply device 6 may be any device that can supply the chopsticks A one by one onto the travel track, and is not necessarily limited to the above configuration, and other known chopstick supply devices may be used as appropriate. It can be used. Furthermore, a chopstick feeding device 10 is formed on the running track 4.

As an example, the illustrated one has an endless chain 11 at the bottom of the base 3.
is arranged around a pair of sprockets, and a motor M is connected to one sprocket to run the chain, and a feed protrusion 12 is provided on the chain 11, which is made to protrude above the base 3. It is formed so as to run on a running track 4. The chopstick tips are placed at the rear of the running track 4 to prevent the tips of the chopsticks A from facing in an arbitrary direction due to warping or twisting and preventing the chopstick bag B from being introduced into the insertion slot, which will be described later. A guide device 13 is provided. For example, as shown in FIG. 3, this guide piece 13' has an L-shaped cross section.
is positioned opposite to the hook-shaped portion 5' formed by the base 3 and the guide side plate 5, and is movable vertically and horizontally, and is attached to the hook-shaped portion 5' by a suitable elastic body 14 such as a coil spring. The chopsticks A are attached so as to be biased toward each other, and the chopsticks A are pressed elastically. As shown in FIG. 4, the guide piece 13' has an inlet 13a made thin and has a large diameter so that chopsticks can easily enter therein, and an outlet 13b is made thin and has a small diameter so that the chopsticks can be pressed against the hook-shaped portion. is preferable. Next, regarding the chopstick bag side device 2, the first
, 5 and 6, what is indicated by the reference numeral 15 is a magazine that stores a certain number of chopstick bags B aligned in the same direction as the travel trajectory 4 of the chopsticks, and is placed in the last stage of the feeding device 10. It is installed so that its front side is along the running track 4.
The front surface includes a locking plate 16 that contacts the backboard C of the insertion opening in the chopstick bag B, and a locking protrusion 1 that contacts the lower edge of the chopstick bag B.
7, which holds the most advanced chopstick bag B1 at this nib, and the locking plate 16 holds the insert back paperboard C1 of the chopstick bag B and moves the chopstick bag B1 forward. In addition, the locking protrusion 17 is set at a height of about 1 mm from the bottom of the magazine 15, and is configured to hook and lock the lower edge of the chopstick bag B1. Further, a regulating piece 15' for regulating the rear end of the chopstick bag is formed on the rear side surface in the direction in which the chopsticks travel. Further, in the magazine 15, there is provided a presser plate 18 that moves forward at the final end of the chopstick bag B. As an example, FIG. 5 shows that a long groove 19 is bored in the front and back direction in the bottom plate of the magazine 15, and a presser plate 18 is slidably attached to this groove 19 with a pin 20, and a guide roller 21 is attached to the front of the magazine. Hang the cable 22 around the pin 20 and attach one end of it to the
A weight 23 is attached to the other end to give the holding plate 18 a tendency to move forward. Furthermore, locking plate 1
A gas jetting nozzle 24 is attached to the front surface of the chopstick bag B1 toward the insertion opening of the cutting edge chopstick bag B1, and the gas jetting nozzle 24 is configured to constantly jet gas from there.

In addition, under such a configuration, if the locking plate 16 and the locking protrusion 17 have the same thickness and are provided on the same plane, the thickness of the back paperboard C portion is equal to the thickness of the bag portion of the chopstick bag B. Because it is half the size,
Even if it is pressed by the presser plate 18, the back paperboard C1 is
Therefore, there was a risk that the chopstick bag B would move or fly out due to the action of the gas injected from the nozzle 24. Therefore, in order to prevent this, the locking plate 16 is attached to the locking protrusion 1.
It is possible to make the paper holding member 25 thicker than 7 and protrude toward the back side, or to attach a paper presser member 25 made of a material such as rubber that generates appropriate frictional resistance to the back side of the locking plate 16 as shown in FIG. shall be. Then, the back paperboard C1 of the chopstick bag B1 is attached to the locking plate 16.
Alternatively, since it is held under constant pressure by the back side of the paper holding member 25 and the chopstick bag B at the rear, it can be kept stationary even by jetting gas. The present invention has the configuration as described above, and operates as follows to put chopsticks A into chopstick bag B.

First, as a preparatory step for the work, a certain number of chopsticks A are put into the hopper 7 with their tips facing the chopstick bag B, and the leveling rotating body 8 is activated.

Then, the chopsticks A are dropped one by one from the outlet 7 along the passage 9 and are held in a stacked state on the traveling track 4 in a line. At this time, it is assumed that the material feeding protrusion 12 is waiting at a suitable location other than the running track 4. On the other hand, a certain number of chopstick bags B are arranged in a line and stored in the magazine 15 so that the back paperboard C of the insertion opening contacts the back of the locking plate 16, and the holding plate 18 is applied to the final end. Touch and press forward. Then, gas is injected from the gas ejection nozzle 24 to the most advanced chopstick bag B. At this time, the back paperboard C1 of the insertion port is on the back side of the locking plate 16, and the gas is blown into the insertion hole from the front of the locking plate 16, so the insertion port is opened securely (Fig. 7A, reference). The operation of the device is started under the above conditions, and when the motor M is started and the chain 11 is run, the feed projection 12 attached thereto runs on the running track 4, and the base Push the chopsticks A1 on the stand 3 forward (see Figure 8). At this time, since the chopstick tip guide device 13 is provided on the travel track 4, even if the chopsticks are warped or twisted, when the chopstick tips enter the entrance of the guide piece 13', they are guided to the base 3 and the guide side plate 5. It acts to bring the vehicle into close contact with the travel track 4 and prevents it from deviating from the running track 4. As a result, when inserting the chopstick tip into the chopstick bag, it always passes through the front of the locking plate 16, so it will surely enter the insertion opening of the chopstick bag B1 opened on the running track 4.
It is pushed into the bag.

In this case, since the width of the chopstick bag B1 is reduced, the lower edge comes off the locking protrusion 17 and is pushed forward by the pressing force of the presser plate 18. (See Figure 9, A, and mouth). In addition, after the chopstick tips reach the bottom of the chopstick bag B1, the chopstick bag B1 is pushed forward together with the chopsticks A1, and the back paperboard C1 of the insertion opening comes off from the locking plate 16, so it naturally moves forward from the front of the magazine 15. It falls off and is taken out. At this time, the rear end of the next bag B2 is regulated by the regulating plate 15', so that it does not move (see the opening in FIG. 10A).
When the cutting edge chopstick bag B1 falls off together with the chopsticks A1 in this way, the chopstick bag B2 at the back is pushed forward, the locking plate 16 is held by the locking protrusion 17, and the insertion opening is opened. While the feed projection 12 of the feed device 10 is opened, the feed projection 12 of the feed device 10 is opened.
After passing through the turn section 1, the chopsticks A reach the upper surface of the base again, travel on the travel track 4, and then push out the chopsticks A placed on the base 3. In this way, the same operation is repeated in synchronization with the rotation of the motor M, and the operation of putting the chopsticks into the chopstick bag is performed continuously. As described in detail above, the present invention includes expanding the insertion opening of the chopstick bag,
This allows for reliable introduction of chopsticks and removal of the chopsticks after they have been placed in a chopstick bag.Furthermore, since no device is required for removal, high-speed operation is possible and work time can be significantly shortened. It is something. Furthermore, since the device configuration is simple, manufacturing costs can be reduced.
