Combinations of articles within the range can be made and discharged from the discharge conveyor 5.

[0003] The ten supply feeders 1 are arranged so that the conveying directions 6 of the articles 4 are parallel to each other, and are provided corresponding to the respective supply hoppers 3. When the corresponding supply hopper 3 becomes empty, the vibrating section 7 vibrates, and the articles 4 in the trough 8 can be sent out from the outlet 8a of the trough 8 and supplied to the empty supply hopper 3. The articles supplied to the supply hopper 3 are supplied to the weighing hopper 9 when the weighing hopper 9 provided below the supply hopper 3 becomes empty, and the weight of the articles is measured. Each of the ten weighing hoppers 9 has first and second two weighing chambers 9a and 9b, and can measure the weight of each article supplied to each of the weighing chambers 9a and 9b. . That is, when the first weighing chamber 9a (or the second weighing chamber 9b) on the right side (or the left side) of the weighing hopper 9 shown in FIG. 13 is empty, it is provided on the right side (or the left side) of the supply hopper 3. The first gate 3a (or the second gate 3b)
Is opened and closed, and the article is supplied to the first measuring chamber 9a (or the second measuring chamber 9b), and the weight of the article is measured. The weight of the article is determined by the load cell 10 supporting the weighing hopper 9.
Weighed by And 10 weighing hoppers 9
The weighing signal of each article obtained by weighing is sent to a central processing unit (CPU). The CPU variously combines the weighing signals to select a combination of the weighing signals whose total weight is within a preset allowable weight range, and stores the articles corresponding to the selected weighing signals. The first or second gate 11a or 11b of the measuring chamber is opened and closed. As a result, the articles selected for the combination are discharged onto the discharge conveyor 5, conveyed by the discharge conveyor 5, and discharged from the discharge port. In this way, a combination of articles having a total weight within the allowable weight range can be sequentially made.

Since the moving speed of the _two cut-out members 37 ₁ and 37 ₂ is faster than the conveying speed of the articles 4 conveyed in the conveying direction 26 due to the vibration of the vibrating section 31, the articles 4 on the trough 30 are intertwined. also, cut out member 37 _1, 37 ₂ and the article 4 to be engaged, forcibly pulled apart by sending from the article of the product supply section 33 side than the article 4 to the engagement mouth 35 in the retracted position shown in FIG. 4 Can be sent from.

Accordingly, since the articles 4 are easily entangled with each other, even if the entangled articles cannot be loosened and sent out by a substantially predetermined weight (or volume) by the transport by the supply feeder 29, the two cutout members 3
7 _1, 37 ₂ and the article 4 to be engaged, can be fed separately from the articles on the trough 30 at the back than that. Of course, in addition to articles that are easily entangled with each other, articles 4 having adhesiveness and adhesiveness can be sent out by approximately a predetermined weight (or volume). As described above, since the articles 4 can be supplied to the cups 14 by approximately a predetermined weight at a time, it is possible to improve the combination weighing accuracy in which the weights of the articles 4 supplied to the cups 14 are combined and weighed. . Then, as a result, the stop time of the combination weigher 13 due to the fact that an allowable combination is not established can be shortened, so that the weighing processing speed can be improved.

Further, as shown in FIG. 5, the front side of the cut members 37 _1, passes through the delivery mouth 35 of the trough 30 is a predetermined time stops at its forward position to move to its forward position, thereby may article 4 to be engaged with the front side of the cut member 37 ₁ is transferred to the next step after the off reliably from clipping member 37 ₁ of the front. The cut member 37 ₂ of the rear side, since the predetermined time stops at a position to close the delivery mouth 35, the article 4 on the trough 30 is sent mouth 3
5 can be kept so as not to spill out.
Can be reliably stopped. In this manner, the article 4 can be reliably sent and stopped, so that the article 4 is not supplied over the upper edges of the cups 14 arranged front and rear on the input stage 15, and It is possible to prevent a weighing error caused by such a situation.

[0041] Further, although less amount of articles 4 on the article delivery unit 32 by the movement of the clipping member 37 _1, 37 ₂ in the transport direction 26, the vibrating unit 31 cuts out the drive cylinder 3
9 ₁ and 39 ₂ vibrate during the extension operation, and the article supply unit 33
The article 4 above can be replenished is transported on the article delivery unit 32, thereby, when the cut-out member 37 _1, 37 ₂ has returned to the retracted position, stagnation was delivery of next and subsequent articles 4 Can be performed sequentially without using

Then, as shown in FIG.
When 7 ₁ and 37 ₂ are moved to the forward position and the article 4 is supplied to each cup 14, the swing drive cylinders 40 ₁ and 40 ₂
Is shortened, whereby each swing arm 38 ₁ , 38
₂ is cut out member 37 ₁ swings predetermined angle counterclockwise direction about the respective pivot axes 48, 48, 37 ₂ is moved to the raised position. And the cutting drive cylinder 3 in the extended state
9 ₁ and 39 ₂ are shortened and cut-out members 37 ₁ and 37 ₂
Moves to the retracted position in the state of being in the raised position (shown by a solid line in FIG. 6). Next, the swing drive cylinders 40 ₁ , 40 ₂
Extend operation, whereby each swing arm 38 ₁ , 38
₂ is returned to the original article supply standby position by cutting member 37 ₁ swings in the clockwise direction by a predetermined angle, 37 ₂ is moved to the lowered position about the respective pivot axes 48, 48 (see FIG. 4). In this way, the lower end portion of the cut members 37 _1, 37 _2,
The two large parallelograms 70, 71 shown in FIGS.
Move along the arrow. In addition, the cutting members 37 ₁ and 37 ₂ that have moved to the forward position and delivered the article 4 return to the retracted position while moving to the ascending position, so that the article 4 on the article delivery unit 32 is moved to the article supply unit 33 side Can be returned to the original retracted position without being pulled back, so that the article 4 having substantially the same weight as the weight of the article 4 previously supplied to each cup 14 can be supplied to each cup 14 again this time. Accordingly, a relatively high combination weighing accuracy can be obtained.

Next, the combination weigher 13 will be described. When the articles 4 are supplied by the article supply device 12 to the respective cups 14 by approximately a predetermined weight, the cups 14 to which the articles 4 have been supplied are supplied.
Is weighed by the four weighing devices 16 shown in FIG. Each of the four weighing devices 16 has a weight detector such as a load cell, and the cup 14 into which the article 4 is input from the input stage 15 on a mounting table provided in each load cell.
Is sent, the total weight of the cup 14 and the articles 4 put in the cup 14 can be measured. An arithmetic control unit provided in the combination weigher 13 calculates the weight of the article 4 by subtracting the weight value of the known cup 14 (each cup 14 has the same weight) from the total weight value. Can be obtained. Then, the four cups 14 into which the weighed articles 4 are put are conveyed onto the staying conveyer 17 at the subsequent stage.

As shown in FIG.
It is a linear conveyor, which can receive the cups 14 discharged from each of the four measuring devices 16 and convey it to the right in FIG. A stopper 72 is provided at the right end, and the cup 72 can be locked by the stopper 72. That is, the stagnant conveyor 17 is constantly driven to rotate by the motor, and each cup 14 on the stagnant conveyor 17 is conveyed to the stopper 72 side and the first cup 1 is moved.
When the stopper 4 comes into contact with the stopper 72, the subsequent cups 14 are sequentially arranged in a line in a state of pressing and contacting with each other, and each cup 14 stops at that position. However, since the stagnant conveyor 17 is constantly driven to be conveyed, the cups 14 arranged in a row on the stagnant conveyor 17 tend to protrude leftward or rightward in the traveling direction. (Not shown) regulates the cup 14 so as not to protrude outside the staying conveyor 17.

A pusher device 73 is provided on the right side of the stagnant conveyor 17 shown in FIG. The pusher device 73 includes first to tenth pushers (not shown). 1st to 10th

According to the article supply apparatus of the present invention, the cutting means moves in the direction of conveyance at a speed higher than the conveying speed of the conveying means, and engages with the cutting means from the articles remaining on the conveying means. Is forcibly separated and sent out from the article outlet of the transport means,
For example, even articles having tackiness or adhesiveness, or articles that are easily entangled with each other can be reliably sent out by a predetermined weight or volume. In other words, it is possible to prevent articles sent out from the article delivery port of the transport means from being connected to the articles remaining on the transport means and to prevent the articles from hanging down at the article delivery port, and also prevent a large lump of articles on the transport means from being delivered. it can.
Furthermore, even if the article on the transporting means is attached to the transporting means and it is difficult to send out the article, it can be reliably sent out. As a result, it is possible to improve the function of sending out articles by a predetermined weight or volume at a time without human intervention.

According to the article supply device of the second invention,
When the cutting means cuts out and sends out the article,
Since the transporting unit transports and prepares the article to be sent out next time by the cutting-out unit, the cutting-out unit can sequentially and sequentially send out the articles, and the sending ability can be improved. When the cutting means is not moving in the transport direction, the transport of the articles by the transport means is stopped, so that the articles can be prevented from spilling out of the article delivery port of the transport means. Thereby, the delivery of the article can be reliably stopped. That is, for example, the first and second gates 3 of the supply hopper 3 shown in FIG.
When the articles are supplied to the supply hopper 3 at a time when the articles should not be supplied to the supply hopper 3, such as when the articles a and 3b close, the supplied articles are sandwiched between the first and second gates 3a and 3b. Then, the sandwiched article causes a measurement error, but such a situation can be prevented.

According to the article supply device of the third invention,
By changing the moving length of the cutting means in the conveying direction by the moving length changing means, it is possible to increase or decrease the weight or volume of the article sent out from the article delivery port. It can be set to send out articles.

According to a fourth aspect of the present invention, there is provided an article supply apparatus for transporting an article engaged with a first cutting means having a relatively long moving length to engage with a second cutting means having a relatively short moving length. This is a configuration that can be forcibly separated from the article on the means and sent out from the article delivery port. Thereby, even when articles that are easily entangled or sticky or sticky are formed into a lump on the transporting means, the first and second pieces having the different lump lengths are moved to the lump of the lump. It can be separated and loosened by the cutting means, and the article can be reliably sent out by approximately a predetermined weight or volume.

According to the article supply device of the fifth invention,
The article engaged with the fourth cutting means by the movement of the fourth cutting means is forcibly separated from the articles on the transporting means engaged with the third cutting means which has stopped moving, and sent out from the article delivery port. Even if articles that are easily entangled or sticky or adherent are clumped on the transporting means, the clumped articles are unraveled and reliably sent out by approximately a predetermined weight or volume. be able to. Then, by moving the fourth cutting means back and forth, it is possible to brush off the articles attached to or entangled with the article delivery port and the fourth cutting means, so that the articles do not hang down from the article delivery port. be able to.

According to the article supply device of the sixth invention,
Since the articles on the transporting means can be held for a predetermined time by the cut-out means, it is possible to prevent the articles from spilling out of the article delivery port by, for example, the transporting force of the transporting means. Thus, when it is not the time to send out the article, the sending out of the article can be reliably stopped.

According to the article supply device of the seventh invention,
Since the surface of the article on the conveying means can be scraped substantially flat by the scraping means, the weight or volume of the article sent out by the movement of the cutting means can be made almost constant. Since the scraping means is provided in the cutting means, the scraping means and the cutting means can be driven by the common cutting drive means.

According to the combination weigher provided with the article supply device according to the eighth invention, since the article supply device of the first invention is provided, the articles are weighed at a predetermined timing at substantially predetermined weights or volumes. Means, which increases the likelihood of a combination of articles having a total weight equal to or close to the target weight, thereby improving the processing capacity of the combination weighing and the combination weighing accuracy. Can be planned. Further, in the conventional combination weigher shown in FIG. 13, when it is attempted to supply articles that are easily entangled or sticky or sticky to the supply hopper by the supply feeder at a predetermined timing by a predetermined weight, manual operation is required. However, according to the combination weigher according to the eighth aspect of the present invention, this manual labor can be reduced or eliminated. This makes it less likely to be affected by the skill of the operator, and allows the combination weigher to operate with a substantially stable processing capacity.
