Conventionally, as shown in FIGS. 3A and 3B, when the processing equipment is a packaging machine, the main body 1 is extended to the opposite side of the band reel 2 provided on the main body 1, and the main body 1 is attached to the side opposite to the band reel 2 provided on the main body 1. A mounting table is fixedly installed in the width direction of the main body, a processing mechanism such as a motor 3 is disposed on this mounting table, and a roller 5 interlocked with the drive mechanism via a chain 4 is attached to the widthwise edge of the main body and the band on the main body. Guide arch 6
Four belts are wound around each of the eight drive rollers in four sets arranged in this manner on the left and right sides of the work table substantially directly below the roller. Furthermore, a small-diameter idle roller that supports the back surface of the belt is supported between each pair of rollers so as to cover the top surface of the main body. The drive roller 5 and the idle roller are supported by bearings on a support plate 7 fixedly installed across the width of the main body so as to withstand the weight of the items to be packed. Processing equipment 1 such as a packaging machine consisting of an automatic packaging machine with a belt conveyor configured as described above is interposed between the transport line 10 having a drive motor 13, and is placed in front of the processing equipment 1 in the transport direction of the transported object W. A phototube 8 is disposed at the phototube 8, and the phototube 8 detects the conveyed object W. During the passage from the front end to the rear end, the encoder or pulse generator 11 is actuated by the detection signal of the phototube 8. , the length of the transported object W is measured, and when the front end of the transported object W reaches below the band guide arch 6 of the packaging machine 1, another phototube 9 detects this, and the measured value is is input and sends a detection signal to the arithmetic and control unit 12 which stores a reference value obtained by halving this measured value, and counts down until the reference value reaches 0. When it reaches 0, this 0 signal is sent. The belt conveyor 15 and/or conveyance line 10 on the top surface of the packaging machine main body 1 is stopped, the packaging machine is started, the belt is wrapped around the center of the transported object W, and the belt conveyor 15, etc. A method was used in which the object to be packaged was detected by rotating it. Although the desired purpose can be achieved by this means, two phototubes are required, and the other phototube 9 is slightly shifted from the processing position C, and the adjustment is complicated because it requires a complex comparison calculation function. However, it also had the disadvantage of being necessarily expensive. In addition, as shown in FIG. 4, in order to send the conveyed object W to the sealing machine 1, which is a processing device, via a right-angled corner 16, the conveyance direction of the primary line 17 is rotated in the same direction as the conveyance direction of the primary line 17. A roller conveyor 20 is provided, and a roller conveyor 20' that rotates in a direction perpendicular to the roller conveyor 20 is attached so as to be able to rise and fall freely, and the roller conveyor 20' is lifted by a stopper 19 that detects when the conveyed object reaches a corner. Alternatively, a means of transferring the object to the secondary line 18 by a raised direction changer (not shown) between both conveyors 20, 20' is adopted. Since the edge must correspond to the packing tape supply position of the sealing machine 1, for this positioning, the sealing machine has an air cylinder that moves forward and backward facing the width direction of the conveyed object on the entrance side in the conveyance direction. It was necessary to install a positioning mechanism, which, together with the direction changing device at the corner, made the entire line large and expensive.

The number of flow pulses is counted until the number of flow pulses reaches a certain total number of pulses PT generated from the front end detection signal of the conveyed object of the position detecting means PH corresponding to a certain distance LA to the processing position C of the processing equipment. The method is characterized in that when this constant total number of pulses PT is counted, the conveyance is stopped and the processing equipment is activated.

Since the transport speed V and the distance LA from the position detection means PH to the processing position are always constant values, if the number of pulses generated per second is P, then the distance LA from the position detection means PH to the processing position is always constant.
The number of pulses P1 counted during the generation of the detection signal from the front end to the rear end of the transported object W during transport by the PH, and the number of pulses after the detection generation position when the rear end of the transported object W passes the position detection means PH. The sum of P 2 is a constant total number of pulses PT, and this total number of pulses PT is the number of pulses counted while moving the distance LA from the processing position C to the position detection means at the conveyance speed V. Therefore, the set position If the distance from C to the front end of the transported object W is X, and the length of the transported object is LT, then PT=(LA/V)P P 1 =(LT/V)P×(1/2) P 2 = {(LA+X)-LT}P/V, so PT=P 1 +P 2 (LA/V)P = (LT/V)P×(1/2) +{(LA+X)-LT}P /V Therefore, X=LT/2. In this way, if the position detection means PH detects the front end of the transported object W and then stops the transport device at the total number of pulses PT, the transported object W of random length will always be located at the longitudinal center in the transport direction. is fed and positioned so that it stops at processing position C.

The details of the present invention will be explained below based on the illustrated embodiments. The general configurations of an automatic packaging machine, a conveyance device, etc., which are examples of processing equipment, are the same as those described above, so a description thereof will be omitted. The position detection means PH is a photo sensor or a phototube, and is provided facing the transport device 10, and is connected to the sequencer SQ. The sequencer SQ is connected to each drive control means of the belt conveyor drive mechanism in the packaging machine main body 1 and/or the drive mechanism of the conveyance device 10. The distance LA from the binding position C, which is the processing position, to the position detection means PH represents the distance from the center of the band guide arch 6, that is, from the binding position C to the photo sensor PH. It is possible to process, ie, bundle, the objects W to be packed at the central position. The conveyance speed of the conveyor device 10 and the conveyor device on the packing machine main body 1 is 1.8 m/min, that is, 300 m/min.
mm/sec, and the sequencer SQ is activated once every 0.01 seconds, or 100 pulses per second (=
The number of pulses PT from the photo sensor PH to the processing position C is (LA/V).
P = (600/300) x 100 = 200 pulses, and when 200 pulses are counted by sequencer SQ,
A movement signal for the packing machine and a stop signal for the belt conveyor are generated together with a stop signal for the conveying device 10. That is, the sequencer SQ does not stop generating pulses even when the passage of the rear end of the object W to be packed is detected by the photo sensor PH. In addition, the sequencer SQ detects when the photo sensor PH is generating a detection signal from the front end to the rear end of the packaged object W, that is, from the ON of the photo sensor PH.
A pulse frequency modulation circuit is incorporated that counts 1 pulse as 1/2 pulse until OFF, and counts 1 pulse as 1 pulse after the photo sensor PH is OFF, that is, after the rear end passage detection signal of the object W to be packaged is generated. ing. In other words, a photo sensor
Count as 50 pulses per second while PH is ON and OFF, and 100 pulses per second after PH is OFF. To explain the content of the above control process, the length
When a LT600mm to-be-packed object W is transferred on the conveyor 10 and the front end position is detected by the photo sensor PH, the photo sensor PH turns on and sends a pulse generation signal to the sequencer SQ, and the sequencer SQ outputs a pulse signal.
Counting of pulses generated with the pulse as 1/2 pulse starts. Therefore, while the photo sensor PH is detecting the object W to be packed, that is, the photo sensor PH is ON.
The number of pulses generated during the sequencer SQ
Now count to the next number of pulses. In other words, after counting (LT/V)P x (1/2) = (600/300) + 100 (1/2) = 100 pulses, the photo sensor PH turns OFF, which means that the rear end position detection signal of the object to be packed W is not detected. Occur. From now on, one pulse is counted as one pulse by frequency modulation, so the number of pulses PT is
Since there are 200 pulses, the belt conveyor on the top of the packing machine body stops after counting the remaining 100 pulses. In other words, after the rear end of the object W to be packaged passes the photo sensor PH, the front end moves forward for 100 pulses before stopping, so 100 pulses x 1 pulse time x V = 100 pulses x 0.01 sec x 300mm/sec=300mm Move forward and stop. Therefore, the front end of the object to be packed W will stop at a position LT + 300 = 600 + 300 = 900 mm from the photo sensor PH,
Since the distance from to the processing position C is 600 mm, the processing position C is 900-600=300 mm from the front end of the object W to be packed, and is located at the center of the length LT600 mm of the object W to be packed.
FIG. 2 is an explanatory diagram of the above. When the length of the object W to be packaged is 1200 mm, from ON to OFF of the photo sensor PH, (LT/V)P x (1/2) = (1200/300) x 100 x (1/2) = 200 pulses Then, PT-200=200-200=0 pulses.In other words, the belt conveyor stops immediately after the photo sensor PHOFF. By increasing the distance LA from the processing position C to the photo sensor PH, it is possible to handle even longer items to be packed. Next, when the length LT of the item W to be packed is 300 mm, from the same calculation formula, (LT/V)P x (1/2) = (300/300) x 100 x (1/2) = 50 pulses Therefore, PT - 50 pulses = 200 - 50 = 150 pulses 150 pulses x time of 1 pulse x V = 150 x 0.01 sec x 300 mm/sec = 450 mm After the photo sensor PH is turned off, that is, the object to be packaged After the rear end of W passes the photo sensor PH, the front end of the object to be packed W moves forward by 450 mm and stops. Therefore, the forward movement of the object W to be packed will stop at a position LT + 450 = 300 + 450 = 750 mm from the photo sensor PH.
Since the distance from to the processing position C is 600 mm, the processing position C is 750-600=150 mm from the front end of the object W to be packed, and the center of the object W in the longitudinal direction is located at the processing position C. In this way, by counting 200 pulses by the sequencer SQ, a conveyor stop signal and a start signal are sent to the packing machine, and the packing is carried out by known mechanisms.The conveyor on the top of the packing machine body is driven again by the packing end signal, and the items to be packed are packed. W is carried out from below the arch 6. Also in the conveyor line shown in Fig. 4, corner 16
If a position detection means PH is provided at the inlet end of the processing equipment, and the packing tape supply position of the sealing machine as processing equipment is set to processing position C, the stop of the roller conveyor 20 rotating in the same direction as the primary line can be controlled in the same way. , it is possible to obtain the same functions and effects as those of the above-mentioned embodiments.

As described above, the present invention provides a means for detecting the position of the object being transported from the front end to the rear end of the object being transported at a constant transport speed to the processing equipment. The pulses during the generation of the position detection signal are counted by the position detection means as 1/2 of the number of pulses counted after the generation of the rear end position detection signal of the conveyed object, and the sum of the two pulse numbers is determined by the processing. Fixed distance to the processing position of the equipment
Count until a certain total number of pulses generated by the front end detection signal of the conveyed object of the position detecting means corresponding to LA is reached, and when this constant total number of pulses is counted, the conveyance is stopped and the Since the device is operated, only one position detecting means such as a phototube is required, and it is possible to provide a positioning and conveying method consisting of a control device that can be configured with a small and inexpensive sequencer and is easy to adjust. It is.
