Description

[Detailed Description of the Invention] (Industrial Application Field) The second invention relates to a conveyance object sorting device for appropriately sorting various objects such as bottles, cans, packages, etc. while they are being conveyed. It is.

(Prior Art) Conventionally, as a bottle selection device, for example,
A device described in Japanese Patent No. 5-24579 is known. In this device, when a bottle is manually selected, the corresponding bottle is selected and transported.

(Problems to be Solved by the Invention) However, with the above-mentioned conventional techniques, when the transport speed of objects increases and exceeds the tracking range of the human eye, sorting becomes impossible. Furthermore, when changing the number of conveyance paths from one to a plurality of conveyance paths, or when sampling a predetermined number of objects consecutively, many human operations are required, which is not efficient.

The present invention was made to solve the problems of the prior art as described above, and its purpose is to provide a sorting device for conveyed objects that can automatically sort objects in various ways in both high-speed and low-speed operations. The goal is to provide the following.

(Means for Solving the Problems) The present invention includes: a drive source; an object pressing means for pressing an object conveyed on a conveyance path to move it in a desired direction I\; and applying the driving force of the drive source to the object pressing means. a coupling means for transmitting/non-transmitting the object and suddenly stopping the object pressing means; and a coupling means provided at a position upstream of the conveyance from the position where the object pressing means presses the object, and for detecting the arrival of the object conveyed on the conveyance path. an object arrival detecting means to be detected; and controlling the coupling means based on the detection output of the object arrival detecting means to drive the object at any timing when the object arrives at the pressing position of the object pressing means. The transport object sorting apparatus is provided with a drive timing control means for controlling whether or not the driving force of the source is transmitted to the object pressing means based on preset setting information.

(Function) According to the above configuration, depending on whether or not the driving force of the drive source is transmitted to the object pressing means that presses the object to be conveyed, the object is pressed only at an appropriate timing when each object arrives at the pressing position. It will be possible to automatically select the necessary objects.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. As shown in the figure, an object 2 such as a bottle is being conveyed from right to left in the figure on a conveyance path 1 such as a belt conveyor. Reference numeral 3 denotes a motor as a driving source, which rotates at an appropriate rotation speed. The rotation of the motor 3 is controlled by the timing gear 4 and the timing bell I~5.
is transmitted to the timing gear 6-'\ and reaches the coupling means 7. The coupling means 7 is, for example, a vacuum clutch or brake, and controls the coupling between the timing gear 6 and the brush body 8 and the sudden stop of the brush body 8.

Coupling means 7, timing gear 6, brush body 8
FIG. 2 shows a perspective view of the constituent parts consisting of the following. As is clear from the figure, the timing gear 6 is fixed to the shaft 9 with a nut 10. The brush body 8 has an annular main body 8A (
Fig. 3) and the hair body 11 implanted on the outer periphery of this main body 8A.
As is clear from FIG. 2, the hair body 11 is in a so-called eccentric state, for example, as the length of the hair changes as it goes around. (Furthermore, a hair body may be implanted in a part of the main body 8A.) The coupling means 7 of the brush body 8 includes a cam 12 for detecting a brush position and a cam 12 for detecting a predetermined rotation. A cam 14 for use is provided. 14A, 12 for brush position detection
The predetermined rotation detection cam 14 has a disc shape, and a notch 131dA is formed at a predetermined portion of the outer periphery (
Of course, the notch portion 13 may be made to protrude and this protrusion portion may be detected by a sensor. ). The cam 12 for detecting a brush position and the cam 14 for detecting a predetermined rotation are fixed to the two brush bodies 8 by a nib. When the two brush bodies 8 are in the initial position, for example, the part with the shortest bristles of the bristles 11 of the brush body 8 faces the conveyance path 1 so as not to press the object 2, and Two brushes 8
A cam 12 for detecting the position of the glass is provided integrally with the
A proximity switch 15 is provided at a position on the housing of the coupling means 7 facing the notch 13 of the coupling means 7 . The notch 14A of the predetermined rotation detection cam 14 forms a predetermined rotation angle with the notch 13 of the plush position detection cam 12,
A cam 14 for detecting a predetermined rotation is positioned, and a stop sensor 16 such as a proximity switch is provided in the housing of the coupling means 7 to detect this notch 14A. The output signals of the proximity switch 15 and stop sensor 16 are provided to drive timing control means 20/\. When the rotation of the motor 3 is transmitted to the two brush bodies 8 by the coupling means 7, the two brush bodies 8 rotate and push out the object 2 located at a position facing the two brush bodies 8 in the conveyance path 1.
The object 2 is moved to the conveyance path 21A among the conveyance paths 21A and 21B arranged in a row. A start sensor 17 for detecting the arrival of the object 2 is provided on the upstream side of the conveyance 81 from the two brush bodies 8. This start sensor 17 and brush body 8
When the distance from the center of object 2 is 11 as shown in the figure, and the diameter (width, etc.) of object 2 is D, the positions of star 1 to sensor 17 are determined so that 11≦D/2. That is, if this condition is not met, the object 2 will be placed in the center of the brush body 8.
When this happens, the next object 2 is about to be detected by the start sensor 17, making it difficult to adjust the rotation timing of the two brushes 8. The output signal of the start sensor 17 is given to the drive timing control means 20. Further upstream of the start sensor 17 is an image sensor 18 such as a camera that obtains data for detecting that the object 2 has a predetermined shape (color, shape, etc.), and an object 2 that determines the detection timing of the image sensor 8. As shown in the figure, when the distance between the shutter sensor 9 and the center of one brush 8 is 12, and the diameter of the object 2 is D, the capacity of the memory circuit 114, which will be described later, is ■By 8, 1
The relationship ≦VM×D needs to be satisfied. This is a necessary relationship to prevent data overflow in memory circuit 114.

Output signals from the image sensor 8 and the shutter sensor 9 are provided to a drive timing control means 20.

The drive timing control means 20 is provided with a setting input means 22 consisting of keys, switches, etc., into which setting information for various driving modes is input. The drive timing control means 20 includes a setting information identification means 23, a first counting means 24, a second counting means 25, a determining means 26, and a transmission timing generating means 27. The setting information identification means 23 detects the input information from the setting input means, and determines that it is "all output",
It identifies which mode setting information is "predetermined ratio sorting", "predetermined number sorting", and "shift register", and provides the result to the transmission timing generating means 27'\. The first counting means 24 inputs "N
" is set. In the second counting means 25, r M in the case of extruding M consecutive objects 2 including the object 2 at which extrusion has started is set from the setting input means 22 or from another input section (not shown). Ru.

The determining means 26 determines whether or not the object 2 has a predetermined form from the data obtained by the image sensor 18, and sequentially outputs data indicating that the object is of the predetermined form and that the object is not of the predetermined form. The transmission timing creation means 27 is the setting information identification means 23
When the identification result indicates the "all eject" mode, the start sensor 17 sends a coupled start signal to the coupling means 7 via the signal line 28 after a predetermined time Δ after the start sensor 17 obtains a signal indicating the arrival of the object 2. give it. As a result, a clutch or the like is engaged within the coupling means 7, the two brush bodies 8 are rotated, and the object 2 in front of the two brush bodies 8 is pressed and moved in the direction of the conveyance path 21A.

Note that the above △t is approximately determined by 0 △t = (D/2>/V) depending on the conveyance speed ■ of the conveyance path 1, and is finally determined by adjustment, and is set and held in the transmission timing creation means 27. When the brush pusher 8 rotates once, a signal (STOP) is obtained from the stop sensor 16, and the transmission timing generating means 27 gives a stop signal to the coupling means 7 via the signal line 29.As a result, within the coupling means 7, , the coupling by the clutch or the like is released, and the rotation of the brush pusher 8 is suddenly stopped by, for example, driving a solenoid valve.Hereafter, a signal indicating the arrival of the object 2 is obtained by the start sensor 17. The transmission timing generating means 27 receives a signal from the stop sensor 16 instructing to stop the predetermined rotation, and the plush body 8 is stopped, and after a reaction time, the plush body 8 is stopped. If the detection signal from the proximity switch 15 is not obtained when the apparatus is stopped and then a start signal is given, the alarm display means 30 is activated to display and output an alarm.

When the identification result of the setting information identification means 123 indicates the "predetermined ratio sorting" mode, the transmission timing creation means 27 sets "N" set in the first counting means 24 to indicate the arrival of an object from the start sensor 17. Each time the receiver receives a signal, it counts down by "1", and when the countdown result becomes "0", the brush double press 8 performs a predetermined rotation (1/2 ．．
1/:3 etc. may be sufficient.

Then, the content of the first counting means 24 is set to "N" again. This operation is repeated below.

When the identification result of the setting information identifying means 23 indicates the "predetermined number sorting" mode, the transmission timing generating means 27 inputs a start signal indicating the start from the setting input means 22 to the second counting means 25. set rM
” starts. Each time a signal indicating the arrival of an object is received from the sensor 17, the process starts counting down by “1” as described above.
The same operations as in the mode of "complete discharge" are performed one after another, and when the countdown result becomes "0", the brush returns to the initial state in which the brush 2 press 8 is no longer rotated.

2. The determining means 26 takes in the data of the image sensor 18 in synchronization with the signal of arrival detection of the object 2 by the shutter sensor 19, uses it as data indicating whether or not it has a predetermined form, and sequentially arranges the data and uses the output of the start sensor 17. A FIFO (first-in-first-out) operation is performed. The transmission timing creation means 27 uses the data from the determination means 26 when the identification result of the setting information identification means 23 indicates the "shift register" mode. In other words, determining means 2
6 holds data corresponding to the capacity (memory circuit 114).

The setting information identification means 23 detects the object 2 from the start sensor 17.
Each time the receiver receives a signal indicating the arrival of the data, the receiver receives the data taken out from within the determining means 26, and when the data is data indicating that the data is in a predetermined format, the above-mentioned "all output" mode is used. Brush the same action as the action 8
Only the object with the predetermined shape is transferred to the conveyance path 2.
It is moved in the direction of 1A.

Specifically, the conveyance object sorting device as described above can be constructed by including drive timing control means 20 consisting of a circuit as shown in FIG.

In FIG. 3, the same components as in FIGS. 1 and 2 are given the same reference numerals, and their explanations will be omitted.

The output signal of the stop sensor 16 is given to the interface circuit H@102 and the timing determination circuit #1103 via the interface circuit 101. The interface circuit 102 has a stop sensor 16 when the brush is pressed 8.
(Actually, -next axis) for a predetermined (for example, 1 rotation, 1/
2 rotations, 1/3 rotation) rotation (hereinafter explained in terms of 1 rotation)
When detected, a stop signal is given to the coupling means 7 via the signal line 29 to cause it to perform a sudden stop operation. The interface circuits 104 and 105 receive the output signals of the proximity switches 15A and 15B and output the output signals to the OR circuit 1.
Send to 06. Proximity switches 15A and 15B correspond to 15 in FIGS. 1 and 2, and in this embodiment, the brush double press 8
Attach two pieces to indicate that it is a rotating part. The output signal of the OR circuit 106 is given to the timing determination circuit 103.

When the power is turned on, the power-on reset circuit 107
Timing discrimination circuit 103, reset mode switch 4 switching time #1108, start/stop switching circuit 109 is initialized by giving a heliset signal, and a start signal is given to interface circuit 110 via signal line 28 to coupling means 7/ \ Reach. As a result, the clutch or the like is engaged within the coupling means 7, and the brush 8 is rotated once. At this time, the stop sensor 16 detects one revolution, and a stop signal is generated at the route of the interface circuits 101, 102 and the signal line 29. After being outputted, a sudden stop is performed by the coupling means 7, and after a predetermined reaction time, the brush 8 is finally stopped at the initial position.

The output signal of the start sensor 17 is applied to an I/N counter 112, a mode switching circuit 113, and a memory circuit 114 via an interface circuit 111. (2) For the /N counter 112, r N J is set by the setting key 115 for sorting one out of "N" items in the "predetermined ratio sorting" mode. The I/N counter 112 receives the output of the start sensor 17 via the interface circuit 111, and counts down by "1" every time it receives the output from the start sensor 17, and counts down by "1" to "0".
”, the output signal 5 is given to the timer circuit 116. The above down count is
This is performed when a permission signal is given from the mode switching circuit 113. 117 to 119 are "all discharged" and "
The selection switches for each mode of "predetermined number sorting" and "shift register" are shown, and various modes such as the "predetermined proportion sorting" mode are selected by the combination of selections of these selection switches 117 to 119. The output signals of the selection switches 117-119 are applied to the mode switching circuit 113 via interface circuits H@120-122. The mode switching circuit 113 determines the mode based on the outputs of the selection switches 117 to 119 of "total discharge", "predetermined number sorting", and "shift register", and the interface circuit 1
A start signal is given to the timer circuit 116 by the output signal of the start sensor 17 from 11, an output signal of the start/stop switching circuit 109, and an output signal of the output signal switching circuit 123, and a permission signal is given to the I/N counter 112. Controls whether or not to use it. Specifically, when the selection switch 117 of the "all output" mode is selected, the mode switching circuit 113 sends a start signal to the timer circuit 116 every time the output signal of the start sensor 17 is obtained from the interface circuit 111 or 6. Also, if the selection switch 118 of the "predetermined number selection" mode is selected,
The mode switching circuit 113 starts the counter 130 from the time when the start/stop switching circuit 109 gives the signal indicating start.
A start signal is given to the timer circuit 116 every time an output signal from the start sensor 17 is obtained until a signal indicating the stop of the motor is given. Furthermore, if the "shift register" mode selection switch 119 is selected,
When the mode switching circuit 113 is given the selection instruction signal from the output signal switching circuit 123, it gives a start signal to the timer circuit 116 when the start signal is given.

Furthermore, when none of the selection switches 117 to 119 are selected, the mode switching circuit 113 provides a permission signal to the /N counter 112 and does not provide a start signal to the timer circuit 116.

The timer circuit 116 outputs a start signal after a predetermined time Δ after the start sensor 17 obtains a signal indicating the arrival of the object 2. This Δt is set by the adjuster 7 124, and is set using the results of adjustment as described above. Timer circuit 116
The start signal output from interface circuit 1
The signal is applied to the coupling means 7 from the signal line 28 via the signal line 25 .

The output signal of the shutter sensor 19 is applied to the memory circuit 114 via the interface circuit 126, and the output signal of the image sensor 18 is applied to the memory circuit 114 via the interface circuit jY@127. As described above, the memory circuit 114 performs FIFO operation with a capacity V4, and at each timing when the output signal is applied by the shutter sensor 19 as shown in FIG. 4 and falls, for example, the output signal of the image sensor 18 is (data signal H/L level) is taken in, and on the other hand, a data signal is output based on the output signal of the start sensor 17 coming from the interface circuit 111.

Note that Tm5eC indicates a range in which data signals cannot be captured. When the reset switch 128 is operated,
A reset signal is applied to the reset mode switching circuit 108 via the interface circuit 129. When the reset mode switching circuit 108 receives a reset signal from the power-on reset circuit 107 or from the interface circuit 129 via the reset switch 128, it clears the contents of the memory circuit 114 and initializes the counter 130. The output signal of the memory circuit 114 is applied to the output signal switching circuit 123 and is applied as a selection instruction signal to the mode switching circuit 113 as well as to the start/stop switching circuit 109. When the start/stop switching circuit 109 receives a sorting instruction signal from the output signal switching port B123, or when the interface circuit F
When the operation signal of the start switch 133 of the "predetermined number selection" mote is given via l@134, the counter 1
At the same time, when the counter 130 receives a count end signal ("OJ"), the counter 130 changes the start signal to a stop signal. This is a counter to which a predetermined number "M" is set in the "number sorting" mode, and the setting of "M" is performed using the setting key 131. The output signal of the counter 130 is sent to an indicator 1 such as an LED via an interface circuit 132.
35 until the count end signal is output.
This is used to indicate that the mode is "Predetermined number selection" mode.

Further, when the timing determination circuit 103 does not receive a start signal from the timer circuit 116, the timing determination circuit 103 detects the notch 13 from the proximity switch 15 (15A, 15B) via the OR circuit 106.
It is activated when a detection signal of 1 is given, and the stop sensor 1
When a detection output is obtained from 6, it is reset, and when a start signal is not received, the proximity switch 15 outputs an alarm if no detection signal is obtained from interface circuit #11.
36. The output signal of the interface circuit &8136 is given to an indicator 137 such as an LED constituting the alarm display means 30 in FIG. .

The operation of the transport object sorting device configured as above will be explained for each mode.

(i) "Total discharge" mode In this mode, "total discharge J mode selection switch 0 switch 117 is selected (for example, sending an L level signal)"
will be done. At this time, the power has already been turned on and the power-on reset circuit 107 outputs a reset signal to reset and initialize each circuit, and the output of the power-on reset circuit 107 activates and activates the coupling means 7.
The stop is performed and the brush 1 body 8 is positioned at the initial position. Therefore, when the object 2 is conveyed on the conveyance path as shown in FIG. 1, the start sensor 17 detects the leading object 2 and sends an output signal to the mote switching circuit 113.

Since the mode switching circuit 113 receives the signal from the selection switch 117 via the interface circuit 120, the timer circuit 113 receives the output signal from the start sensor 17.
A start signal is given to 16. As a result, the timer circuit 116 is started and the time set by the regulator 124 is set.
After that, a start signal is applied to the coupling means 7 via the interface circuit 125 and the signal line 28. As a result, the primary side and the secondary side of the coupling means 7 are connected, the brush 8 rotates once, the stop sensor 16 detects one rotation, and the output signal is sent to the interface circuit 101102.
A stop signal is applied to the coupling means 7 from the signal line 29 via the signal line 29. As a result, the primary side and the secondary side of the coupling means 7 are separated, and the secondary side is suddenly stopped. Thereafter, the same operation is repeated every time the start sensor 17 detects the arrival of the object 2, and all the objects 2 are pressed against the conveyance path 21A side I\. FIG. 5 shows the operation of the ``total ejection J mode'' in which the object 2 is pushed toward the conveyance path 21A after the external signal from the selection switch 117 is set to L level. Reference numeral 400 indicates mechanical parts such as a timing gear 6 and a brush pusher 8 attached to the coupling means 7.

(il>"Predetermined ratio selection" mode In this mote, "N" is set in the I/N counter 112 in advance, and the selection switches 117 to 119 are not selected (no significant signal is given to the interface circuits 120 to 122). .As a result, the mode switching circuit 113
While the /N counter 112/\ permission signal is given, a start signal is not given to the timer circuit 116. Here, if "2" is set as "N", the I/'N counter 112 counts down based on the detection signal from the start sensor 17 due to the arrival of the object 2, and the I/'N counter 112 counts down to "0" every time two objects 2 arrive. ” and gives a start signal to the timer circuit 116J\.

This causes timer circuit 116 to be activated and regulator 124 to
Interface circuit 1 after the time △ set by
25. Apply a start signal to the coupling means 7 via the signal line 28. As a result, the brush double pusher 8 rotates once and stops suddenly every time two objects 2 arrive, and as shown in FIG.
It is divided into @21B. In FIG. 7, "N" is entered in the I/N counter 112 and r5. is set, and one in five objects 2 is pushed out to the conveyance path 21A. FIG. 8 shows two sorting devices according to an embodiment of the present invention.
A system is shown in which the number of transport paths 21C after sorting is increased compared to the cases shown in FIGS. 6 and 7 by using a stand. Then, by increasing the rotation speed of the motor of the upstream side of the sorting device, for example, the pressing force of the object pressing means 3 is made stronger than that of the downstream side, and the object 2 is pushed onto the conveyance path 2.
Make sure to press it all the way to C. Further, as shown in FIG. 8, rNJ of the I/N counter 112 of the sorting device provided on the upstream side and the downstream side is "3" and "2", respectively.
”. The above “predetermined percentage sorting” mode is
This is useful when dividing lines, for example, when the capacity of the machine located upstream from the sorting device (e.g., manufacturing machine) exceeds the capacity of the machine downstream from the selection device (e.g., packaging machine). be.

(River) "Predetermined number sorting" mode In this mode, the counter 1 is selected by the preset key 131.
30 is set to a predetermined number "M", and the selection switch 118 is selected. As a result, the mode switching circuit 113 starts and
The output of stop switching time jY1109 is adopted.

When the operator operates the start switch 133 of the "predetermined number sorting" mode at the required time, a pulse of the star 1 signal as shown in FIG. It will be done. As a result, the start/stop switching 4 times #1109 starts up the counter 130 and gives a start signal to the mode switching circuit 113. Then, the mode switching circuit 113 performs the same operation as in the "all-out" mode described above. This action causes the incoming objects 2 to be pressed one after another. At this time, the counter 130 continues to count down every time the output signal of the timer circuit 116 becomes a start signal, and when it counts down to zero, an end signal is given to the start/stop switching circuit 109J, and the start/stop switch is started/stopped. The circuit 109 uses the signal sent to the mode switching circuit 113 as a stop signal.

As a result, the mode switching circuit 113 switches between the evening and the current mode switching circuit 1.
The operation of giving the start signal to 16 is stopped. Therefore, after the start switch 133 is operated, the mode switching circuit 113 controls the number "M" of objects 2 set in the counter 130.
Since the start sensor 17 outputs a start signal every time the start sensor 17 detects the arrival of the object 2, r M objects 2 are pressed. FIG. 9 shows a state in which r M objects 2 are pressed toward the transport path 21A in this manner. This mode is effective when performing a sampling inspection of M objects 2.

(IV) "r shift register" mode In this mode, the image sensor 18 and shutter sensor 19
are set as explained using FIG.

Also, the selection switch 119 is selected. Then, the mode switching circuit 113 adopts the output of the output signal switching circuit 123. Furthermore, when the power is turned on later, the power-on reset circuit 107 operates and the memory circuit 114 is cleared. Note that in this embodiment, the image sensor 18
detects whether it is black or white, and correspondingly, rl(H)' and '
0 (L)J signal is output, and this is the memory circuit 11.
4, and when the stored contents are read out, rl(H)'' is configured such that a sorting instruction signal is output from the output signal switching circuit j\@123. Now, when the object 2 arrives at the position of the image sensor 18, the detection signal of the image sensor 18 is taken into memory #1114 at the timing of the fall of the output signal of the shutter sensor 19. This captured signal is read out when a detection signal is obtained from the start sensor 17. If the read signal is “16 (H)”, the sorting instruction signal is output from the output signal switching circuit 12.
Output from 3. The mode switching circuit 113 thereby gives a start signal to the timer #1116, and the timer circuit 116 gives a start signal to the coupling means 7 with a delay of Δ from this. As a result, the brush 8 rotates only when the "black" object 2 arrives, and only this "black" object 2 is pressed onto the conveyance path 21A (as shown in FIG. 10). In such a mode, the image sensor 18 can be used as a television camera, and by having an image processing device or the like perform the determination of defective products and inputting the output to the interface circuit 127, it can be used for defective product selection, as well as for checking reference points. is also valid.

The above are the basic operating modes of the sorting device of this embodiment, but this embodiment can further execute the following three modes.

(■) Combination mode of "predetermined proportion selection" mode and "predetermined number selection" mode In this mode, the output signal of the interface circuit 132 is inputted to the interface circuit 121. In addition, the I/N counter 112 has “N”
” is set to, for example, “2”, and the counter 130 is set to, for example, “5” as the predetermined number “M”. In this way, when it comes to starting, initially the start switch 13
3 is not operated, the output signal of the start/stop switching circuit 109 indicates stop, and the interface circuit 12
Since it also functions as an inactive signal for 1, the mode switching diagram FI@113 is the selection switch 117-1
19 is detected, and the "predetermined proportion sorting" mode is executed. As a result, initially, as explained with reference to FIG.
being pushed to the side. In this state, when the operator operates the start switch 133 at an appropriate time, a start signal is given to the start/stop switching circuit 109, and the start/stop switching circuit 109 sends a signal to the mode switching circuit 113 and the interface circuit 121 to indicate startup. Switch as follows. As a result, the mode switching circuit 113 receives the same signal 8 as when the selection switch 118 is selected via the interface circuit 121, and uses the output signal from the start/stop switching diagram B113 to The number "M" set in the counter 130, which is five pieces, are pushed out to the conveyance path 21A side.

When this operation is completed, the start/stop switching circuit 109 receives the output from the counter 130 and transfers it to the interface circuit 12.
In order to return the signal to 1 to indicate stop, the same signal as when the selection switch 118 is not selected is given to the mode switching circuit 113 via the interface circuit 121. returns to the "predetermined percentage sorting" mode again. FIG. 11 shows the state in which objects 2 are sorted by the above operations.

(Vl)rCombination mode of "predetermined number selection" mode and "shift register" mode. In this mode as well, the output signal of the interface circuit 132 is connected to be inputted to the interface circuit 121. Further, the image sensor 18 and the shutter sensor 19 are set as explained in FIG.
30 is set to "M" and the selection switch 119 is selected. In the shifting state, the mode 9 switching circuit 113 receives a signal from the interface circuit #1122 according to the selection of the selection switch 119, and executes the "shift register" mode. At this time, the 10th
In the same way as explained with reference to the figure, move the black object to the transport path 2.
Push it to the iA side. The signal “1” corresponding to this black object 2
(H)” is read out from the memory circuit 114,
The output signal switching circuit 123 sends a selection instruction signal to the mode switching circuit 113 and also sends a start signal to the start/stop switching circuit 109. As a result, the start/stop switching circuit 109 starts the counter 130, and the mode switching circuit 113 and the interface circuit 121.
Switch the signal given to the device to indicate activation. This allows the mode switching circuit 113 to switch between the interface circuit 12 and
1 and 122 to receive selection signals from both selection switches 118 and 119. In such a case, the mode switching circuit 113 prioritizes the selection of the selection switch 118 and operates using the output signal of the start/stop switching circuit 109. When the black object 2 arrives, the pushing operation by the brush 8 is started, and the force is 0. The "M" objects 2 set on the counter 130 are pushed onto the conveyance path 2.
It is pushed to the 1A side. When this operation is completed, the start/stop switching circuit 109 receives the output of the counter 130 and sends a signal to the interface circuit 121 to indicate stop. Signal and interface circuit 12 similar to when is not selected
A signal when the selection switch 119 is selected is applied via the switch 2, and the operation returns to the 1° shift register mode.

Furthermore, when more black objects 2 arrive, the mode shifts to the "predetermined number sorting" mode in the same way as above. A state in which objects 2 are sorted by such an operation is shown in FIG. This mode is convenient when extracting several items from reference points or objects that have been selected as defective in a sampling inspection process or the like.

(Vli) Mode for sorting M into L pieces This mode is
In the "predetermined number sorting" mode, as shown in FIG.
Connect the output terminal of 02 to interface circuit #1134. Here, the counter 202 has a set value rl.

Assume that "5" is set as rMJ, and "2" is set as rMJ in the counter 130. Then counter 2
02 outputs a pulse every time five objects 2 arrive by the start sensor 17, so an operation corresponding to the case where the start switch 133 is operated every time five objects 2 arrive, and the transfer path 21A side A "predetermined number sorting" mode is performed in which two objects 2 are pressed against each other. FIG. 13 shows the state in which objects 2 are sorted by operating in this mode. Such a mode is convenient to apply when the number of objects 2 to be flowed for each line is controlled, especially when the processing capacity of each line is different.

According to the sorting device configured as described above, objects 2 can be appropriately sorted using a necessary mode. At this time, changing the mode is also relatively easy.

In the above embodiment, the DIR switch 20 in FIG.
Although the counter 1 and the counter 202 are installed externally, they may be built-in and the connection may be changed using an appropriate switch or the like. Further, the path for guiding the output signal of the interface circuit 132 to the interface circuit 121J may also be provided from the beginning and connected/disconnected using a switch or the like.

Further, the circuit shown in FIG. 3 can also be constructed by a microcomputer. That is, the microprocessor is configured to use a program in the main memory to execute a corresponding mode from the selected state of the selection switches 117 to 119. And memory times #! 114 is realized as a FIFO memory, and the I/N counter 112, timer circuit 116, and counter 130 are realized by software. Further, the data from the start sensor 17 and the stop sensor 16 are taken in and a start signal and a stop signal are applied to the coupling means 7 at the above-mentioned timing.

Furthermore, the coupling means 7 is not limited to a vacuum clutch or brake, and may be an electromagnetic clutch, for example, and the brush 8 is not limited to a brush as long as it presses against an object, such as a piston or an eccentric elastic member. The body can also be used. Further, each sensor may appropriately employ an optical sensor, a magnetic sensor, or the like. The image sensor 18 is not limited to an image sensor, but may also be a sensor that detects the shape of the object 2 depending on the installation position (for example, if the object 2 has a protrusion, detects the protrusion of the flowing object 2). It may be a sensor installed to do so.

[Effects of the Invention] As explained above, according to the present invention, the timing at which each object reaches the pressing position can be adjusted depending on whether or not the driving force of the drive source is transmitted to the object pressing means that presses the object to be conveyed. Because it is controlled so that pressing is performed only at the appropriate timing, it does not matter whether the conveyance is high or low speed.
Objects can be automatically sorted in various ways.
