Description

The present invention relates to a transport and accumulation device for stacking and accumulating a plurality of objects to be transported.

Conventionally, there is known a transport / accumulation device that includes a transport unit for transporting an object to be transported and an accumulation unit, drops the object to be transported discharged from the transport unit toward the accumulation unit, and stacks the objects to be transported to the accumulation unit.
In such a transport / accumulation device, the drop distance until the transported object discharged from the transport section is accumulated in the collection section is important.
For example, when the drop distance is short, the discharged object may collide with the integrated portion or the like, and the object to be conveyed may be damaged or the object to be conveyed may be turned upside down. If the drop distance is long, the discharged object may not be properly stacked on the integrated section and may fall from the integrated section, the transported object may be turned upside down, or the transported object may be on the side surface of the integrated section. It may be accumulated so as to lean against it.
From these things, it is necessary to set the fall distance to an appropriate distance.

Patent Document 1 discloses a transport and integration device capable of making the fall distance constant. The transport and integration device disclosed in Patent Document 1 will be described with reference to FIG.
The flat parts to be conveyed are conveyed by the conveyor belt 101 and the guide 105, which are the conveying portions, and fall from the end of the guide 105, which is the discharge end of the conveying portion, to the magazine 115, which is the accumulating portion, and are accumulated. It is equipped with a lifter 116 that moves the magazine 115 up and down, and a photoelectric device 117 that projects light rays onto the top flat component integrated in the magazine 115 and receives reflected light from the flat component. The photoelectric device 117 is provided from the flat component. By lowering the lifter 116 while receiving the reflected light of, the height of the upper surface of the uppermost flat component integrated in the magazine 115 is always slightly lower than the height of the terminal insertion position of the guide 105. It is held in the position of, so that the fall distance can be made constant.

The second conveyor division speed V21 is determined based on the following formula by setting the division distance (gap size) L and the division time M.
V21 = L ÷ M
The division distance L can be set to a value between 1 and 999 mm. Depending on the weight of the object to be transported and the slipperiness of the surface, the actual gap between the groups of objects to be transported may differ from the set division distance L. Therefore, a wide range in which the division distance L can be set is provided. ..
The third conveyor fast-forward speed V31 can be set to a value in the range of 1 to 100 m / min, and is set so that the third conveyor fast-forward speed V31> the third conveyor normal speed V30. In the embodiment, V31 = 70 m / min is set.

However, the first conveyor normal speed V10, the second conveyor normal speed V20, the third conveyor normal speed V30, the second conveyor division speed V21, the second conveyor damming speed V22, and the third conveyor fast-forward speed V31 are the respective speeds and objects. The preferred speed varies depending on the thickness, type, shape, number of objects to be transported as a group, and the like, and thus the speed is not limited to the range of the embodiment.
It should be noted that the number of objects to be transported, that is, the number of objects to be transported in the group of objects to be transported (referred to as a batch in the following description), is determined by the control unit before starting the divisional transport and integration operation. Set to 4 respectively. For example, the monitor 6 is touch-operated to set.

As shown in FIG. 1, the accumulating unit 3 includes an accumulating pocket 30 located on the discharge side of the third conveyor 22.
As shown in FIG. 6, the accumulation pocket 30 is moved in the vertical direction by the vertical movement device 40. The vertical movement device 40 is moved by the lateral movement device 50 in a direction perpendicular to the transport direction of the object to be transported.
Therefore, the accumulation pocket 30 moves in the vertical direction and is moved in the direction perpendicular to the transport direction of the object to be transported.
Although only one accumulation pocket 30 is shown in FIGS. 1 and 6, two accumulation pockets 30 are provided in a direction perpendicular to the transport direction of the object to be transported.

As shown in FIG. 6, the accumulation pocket 30 has an upper surface portion 30a opened so that the conveyed object can enter and take out, and a front surface portion 30b facing the third conveyor 22 opened so that the conveyed object can enter. It has a bottom surface portion 30c on which the transported object is placed, a rear surface portion 30d that regulates the position of the transported object that has entered, and two side surface portions 30e. In FIGS. 1 and 2, one side surface portion is omitted.
The rear surface portion 30d is a surface portion that faces the front surface portion 30b in the transport direction of the object to be transported. The side surface portion 30e is a surface portion facing each other in a direction perpendicular to the transport direction of the object to be transported.
Since the accumulation pocket 30 is attached to the vertical movement member 41 of the vertical movement device 40 and is detachably attached, the accumulation pocket 30 suitable for the shape and size of the object to be transported can be replaced and attached.

As shown in FIG. 2, the accumulation pocket 30 is provided so that the opened front surface portion 30b faces the discharge side end portion 22-1a of the third conveyor 22, and the batch to be transported to be discharged from the third conveyor 22. Are sequentially dropped into the accumulation pocket 30 and accumulated in a stacked state.

The configuration of the accumulation pocket 30 will be described with reference to FIGS. 7 to 9.
On the upper surface of the plate-shaped bottom member 31, a plate-shaped first side surface member 32a constituting the side surface portion 30e, a plate-shaped second side surface member 32b, and a plate-shaped third side surface member 32c convey an object to be transported. They are provided at right angles to each other at right angles. A prismatic support member 33 faces in the front-rear direction between the first side surface member 32a and the second side surface member 32b and between the second side surface member 32b and the third side surface member 32c on the upper surface of the bottom surface member 31. Each of the two is attached, and the upper surface of the support member 33 is the bottom surface portion 30c. The first, second, and third side surface members 32a, 32b, and 32c are fixed to the support member 33.
A cylindrical contact member 34 is attached to the rear portion of each support member 33 in the vertical direction, and the contact member 34 is a rear surface portion 30d.

An object to be laminated 30f is formed between the first side surface member 32a and the second side surface member 32b and between the second side surface member 32b and the third side surface member 32c, respectively. That is, the first, second, and third conveyors 20, 21, and 22 transport the two objects to be transported side by side in the direction perpendicular to the transport direction, and the two objects to be transported from the third conveyor 22 are perpendicular to the transport direction. The accumulation pocket 30 has two laminated objects 30f in a direction perpendicular to the conveying direction of the conveyed object, and the conveyed object 7 has two as shown by the two-dot chain line. It is designed so as to enter and accumulate in each of the three transported object laminated portions 30f. The front side portion of the first side surface member 32a and the second side surface member 32b on the opposite surfaces, the front side portion of the second side surface member 32b and the third side surface member 32c on the opposite surfaces, and the support member 33. Each of the front side portions on the upper surface is chamfered to guide the transported object so that it does not get caught when entering the transported object laminated portion 30f.
If the first, second, and third conveyors 20, 21, and 22 convey one item to be conveyed 7 in a direction perpendicular to the transfer direction, the accumulation pocket 30 has one layered portion 30f to be conveyed. It can be configured.

The vibration generator 35 is attached to the third side surface member 32c of the accumulation pocket 30.
When the vibration generator 35 generates fine micro-vibrations, the fine micro-vibrations transmitted through the third side surface member 32c vibrate the entire accumulation pocket 30, and the rear end surface of the object to be transported 7 and the contact member 34 that are being accumulated repeatedly repeat. Since the side end faces of the objects to be transported and the first, second, and third side surface members 32a, 32b, and 32c are repeatedly in contact with each other, the objects to be transported 7 can be aligned and stacked.
The vibration generating member 35 is not limited to the third side surface member 32c, and can be attached to any member constituting the accumulation pocket 30.
A pair of plate-shaped mounting members 36 are mounted downward on the lower surface of the bottom member 31, and the mounting member 36 is fixed to the vertical movement member 41 with bolts 37 and mounted.

As shown in FIG. 6, the lateral movement device 50 includes a fixing member 51, a lateral movement member 53 supported by the fixing member 51 so as to be movable in a direction perpendicular to the transport direction of the object to be transported, and lateral movement. It has a lateral movement mechanism 54 that moves the member 53.
The lateral movement mechanism 54 includes a mechanism for moving the lateral movement member 53 using a cylinder, a feed screw and a nut member, and a motor for rotating the feed screw to move the lateral movement member 53, and a pulley rotated by a motor. A conventionally known material such as one in which a cord is wrapped around the cord and the laterally moving member 53 is moved by the cord can be used.
Two vertical moving devices 40 are attached to the lateral moving member 53 at right angles to the transport direction of the object to be transported, and the integrated pockets 30 are attached to the two vertical moving devices 40, respectively. By moving the moving member 53, the two accumulation pockets 30 can be simultaneously moved in the direction perpendicular to the transport direction of the object to be transported.

Based on FIGS. 10 and 11, the movement of the accumulation pocket 30 in the direction perpendicular to the transport direction of the object to be transported will be described.
In FIGS. 10 and 11, one side in the direction perpendicular to the transport direction of the transported object (the right side when viewed from the upstream side to the downstream side in the transport direction of the transported object) is the operation side, and is perpendicular to the transport direction of the transported object. The other side in the above direction (the left side when viewed from the upstream side to the downstream side in the transport direction of the transported object) is the driving side.
The accumulation pocket located on the driving side of the two accumulation pockets arranged in the direction perpendicular to the transport direction of the object to be transported is referred to as the driving side accumulation pocket 30-1, and the accumulation pocket located on the operation side is referred to as the operation side accumulation pocket 30-2. And.

As shown in FIG. 10, in the state where the lateral movement member 53 is moved to the operation side, the driving side accumulation pocket 30-1 is the accumulation position, and the operation side accumulation pocket 30-2 is the operation side take-out position.
As shown in FIG. 11, in the state where the lateral movement member 53 is moved to the driving side, the operation side accumulation pocket 30-2 is the accumulation position, and the driving side accumulation pocket 30-1 is the drive side extraction position.
The accumulation position is a position where the accumulation pockets 30-1 and 30-2 continuously face the discharge side end portion 22-1a of the third conveyor 22 and accumulate the objects to be transported. The take-out position is a position where the discharged side end portion 22-1a of the third conveyor 22 is separated from the conveyed object in a direction perpendicular to the conveying direction, and the accumulated conveyed object is taken out.

As shown in FIG. 6, the vertical movement device 40 includes a vertical movement member 41, a main body 42, and a vertical movement mechanism 43. The vertical movement member 41 is supported by the main body 42 so as to be movable in the vertical direction, and the main body 42 is attached to the lateral movement member 53.
The vertical movement mechanism 43 includes a feed screw 43a rotatably attached to the main body 42 in the vertical direction, a nut member 43b screwed into the feed screw 43a, and a motor 43c for rotating the feed screw 43a. The nut member 43b is supported on the main body 42 so as to be movable in the vertical direction without rotating, and the nut member 43b and the vertical movement member 41 are connected to each other.
By rotating the motor 43c in either forward or reverse direction and rotating the feed screw 43a in either forward or reverse direction, the nut member 43b moves upward, so the vertical movement member 41 also moves upward, and the accumulation pocket 30 starts integration. Move to the upper position.

When the accumulation pocket 30 is in the upper position, the bottom surface portion 30c approaches the discharge side end portion 22-1a of the third conveyor 22 and the vertical distance between the two is short, and the bottom surface portion 30c of the discharged object 7 is discharged. The fall distance to is short.
By rotating the motor 43c in the forward / reverse direction and rotating the feed screw 43a in the forward / reverse direction, the nut member 43b moves downward, so that the vertical movement member 41 also moves downward and the accumulation pocket 30 moves downward. do. As the accumulation pocket 30 moves downward, the bottom surface portion 30c is farther away from the discharge side end portion 22-1a of the third conveyor 22, the vertical distance between the two is long, and the bottom surface portion 30c of the discharged object 7 is discharged. The fall distance to is longer.
The driving side integrated pocket 30-1 is moved up and down by one vertical moving device 40 attached to the lateral moving member 53, and the operation side integrated pocket 30-2 is the other vertical moving device attached to the lateral moving member 53. Since it is moved up and down by 40, the prime mover side accumulation pocket 30-1 and the operation side accumulation pocket 30-2 can be moved up and down independently.

The operation of transporting and accumulating the transported object will be described.
When starting the transport and accumulation operation, one of the driving side accumulation pocket 30-1 and the operation side accumulation pocket 30-2 is set to the accumulation position and the upper position, and the other accumulation pocket is set to the take-out position. Is in a state where it can be accumulated.
For example, as shown in FIG. 12A, the driving side accumulation pocket 30-1 is set to the accumulation position and the upper position, and the operation side accumulation pocket 30-2 is set to the take-out position.
The first conveyor 20 drives the transfer speed V1 as the first conveyor normal speed V10, the second conveyor 21 drives the transfer speed V2 as the second conveyor normal speed V20, and the third conveyor 22 drives the transfer speed V3 as the third conveyor. It is driven at a normal speed of V30. The damming stopper 24 is set to a non-damping position so that the damming operation is not performed. The number N of the objects to be transported to be accumulated in the accumulation unit 3 is set in the control unit 4. The number N to be set is a desired number.

As shown in FIG. 12A, in the first conveyor 20, the transported objects 7 are continuously supplied from the supply unit 1 at a constant speed, and the transported objects 7 have a constant gap in the transport direction. It is transported in a state of being passed to the second conveyor 21.
Since the second conveyor normal speed V20 is lower than the first conveyor normal speed V10, the second conveyor 21 first passes the object to be conveyed from the first conveyor 20 to the second conveyor 21. The object to be transported 7 is transported in a state of being displaced and overlapped so that the front surface of the bottom surface of the object to be transported 7 to be delivered later (downstream side in the transport direction) overlaps the upper surface of the object to be transported 7.
The amount of misalignment (overlap length in the transport direction) between the previously delivered object 7 and the later delivered object 7 is the speed difference between the first conveyor normal speed V10 and the second conveyor normal speed V20. That is, since it changes depending on the second conveyor normal speed V20, the second conveyor normal speed V20 is determined so as to have a desired magnitude of the deviation overlap amount.
Further, the length of the object to be transported 7 that comes into contact with the transport surface of the second conveyor 21 is important for the stable operation of the batch division, contrary to the amount of misalignment and overlap.

Every time one conveyed object 7 is passed from the first conveyor 20 to the second conveyor 21, a counting signal is sent to the control unit 4. The control unit 4 counts the number of objects to be conveyed 7 passed to the second conveyor 21 based on the counting signal. The counting timing includes a method of counting when the counting signal is sent to the control unit, a method of counting when the counting signal is no longer sent to the control unit 4, and the like. It suffices as long as one sheet is counted every time it is passed to the second conveyor 21. Further, when the counting sensor 23 continues to detect the transported object for a predetermined period of time, the control unit 4 may output an error signal.
When the counted number matches the set number N of the objects to be transported, the transfer speed V2 of the second conveyor 21 is switched from the second conveyor normal speed V20 to the second conveyor division speed V21.
Since V21> V20, as shown in FIG. 12 (b), the number of items to be transported and the number of items to be transported 7-1, which are set by counting from the initially supplied items 7-3, are followed by the items to be transported 7-1. A gap S is formed between the object to be transported 7-2 and the object to be transported 7-2, and the batch 8 is formed.
The first delivered object 7-3 is the conveyed object on the most downstream side in the conveying direction of the batch 8, and is the first conveyed object of the batch 8. The number 7-1 to be transported in the batch 8 is the transported object on the most upstream side in the transport direction of the batch 8, and is the transported object at the tail of the batch 8.

The transfer speed V2 of the second conveyor 21 is switched to the normal speed V20 of the second conveyor when the set division time M elapses.
When the batch 8 is conveyed by the second conveyor 21 and the conveyed object 7-3 at the head of the batch 8 reaches the sensor 25, the sensor 25 sends a detection signal to the control unit 4 to cover the tail of the batch 8. When the conveyed object 7-1 passes through the sensor 25, the sensor 25 does not send the detection signal to the control unit 4. That is, the sensor 25 continues to detect the batch 8 until one batch 8 passes.
Since the detection signal is not sent after being sent from the sensor 25, the control unit 4 assumes that the detection is completed after the sensor 25 starts detecting the batch 8, and the entire batch 8 reaches the delivery side portion of the second conveyor 21. Judge that it was transported. That is, the sensor 25 is for detecting that the entire batch 8 has been conveyed to the delivery side portion of the second conveyor 21. Further, if a detection abnormality such as the sensor 25 not detecting the transported object occurs even though the damming stopper 24 is in the stop position, an error signal may be output from the control unit 4. good.

The batch 8 is passed from the second conveyor 21 to the third conveyor 22, and the batch 8 is conveyed by the third conveyor 22 and discharged toward the driving side accumulation pocket 30-1. When the conveyed object 7-3 at the head of the batch 8 conveyed by the third conveyor 22 reaches the receiving side sensor 26, the receiving side sensor 26 sends a detection signal to the control unit 4, and the conveyed object at the tail of the batch 8 is conveyed. When the object 7-1 passes through the receiving side sensor 26, the receiving side sensor 26 does not send the detection signal to the control unit 4. That is, the receiving sensor 26 continues to detect the batch 8 until one batch 8 passes.
Since the control unit 4 does not send the detection signal after the detection signal is sent from the receiving side sensor 26, it is assumed that the detection is completed after the receiving side sensor 26 starts detecting the batch 8, and the entire batch 8 is on the third conveyor 22. It is judged that the product has been transported to the receiving side. That is, the receiving side sensor 26 is for detecting that the entire batch 8 has been conveyed to the receiving side portion of the third conveyor 22. Further, when an abnormality is detected such as when the receiving side sensor 26 continues to detect the object to be transported while the dam stopper 24 is in the stop position, an error signal is output from the control unit 4. You may try to do it.

When the batch 8 is further conveyed by the third conveyor 22 and the conveyed object 7-3 at the head of the batch 8 reaches the discharge side sensor 27 as shown in FIG. 12 (c), the discharge side sensor 27 sends a detection signal. It is sent to the control unit 4. The control unit 4 determines that the object to be conveyed 7 has started to be discharged from the third conveyor 22, and drives and controls the vertical movement device 40 of the driving side integrated pocket 30-1 to start descending the driving side integrated pocket 30-1. ..
As shown in FIG. 12 (d), the batch 8 discharged from the third conveyor 22 falls toward the driving side accumulation pocket 30-1, and the head to be conveyed 7-3 is placed on the bottom surface portion 30c. Then, the objects to be transported 7 are sequentially stacked on the pile. At this time, since the driving side accumulation pocket 30-1 is lowered, it can be accurately stacked and accumulated in the correct posture.

When the rear end of the object to be transported 7-1 at the tail of the batch 8 is separated from the sensor 25, the sensor 25 does not detect the batch 8 and does not send a detection signal to the control unit 4, so that the control unit 4 described above. As described above, it is determined that the entire batch 8 has been conveyed to the delivery side portion of the second conveyor 21, and the transfer speed V2 of the second conveyor 21 is switched from the second conveyor normal speed V20 to the second conveyor damming speed V22. That is, when the entire batch 8 is conveyed to the delivery side portion of the second conveyor 21, the transfer speed V2 of the second conveyor 21 is switched from the second conveyor normal speed V20 to the second conveyor damming speed V22.

As shown in FIG. 13A, the transported object 7 of the batch 8 is further accumulated in the driving side accumulation pocket 30-1, and the rear end of the transported object 7-1 at the tail of the batch 8 is from the receiving side sensor 26. When separated, the receiving side sensor 26 does not detect the batch 8 and does not send a detection signal to the control unit 4, so that the control unit 4 determines that the entire batch 8 has been conveyed to the receiving side portion of the third conveyor 22. The dam stopper 24 is moved to the stop position, and the transfer speed V3 of the third conveyor 22 is switched from the third conveyor normal speed V30 to the third conveyor fast-forward speed V31. That is, when the entire batch 8 is conveyed to the receiving side portion of the third conveyor 22, the damming stopper 24 is set to the damming position, and the third conveyor 22 is set to the third conveyor fast-forward speed V31.

When the dam stopper 24 is in the stop position, as shown in FIG. 13A, the subsequent batch 8-1 on the second conveyor 21 located on the downstream side of the batch 8 on the third conveyor 22 in the transport direction. It can be stopped. That is, as shown in FIG. 13B, since the conveyed object 7-3 at the head of the succeeding batch 8-1 comes into contact with the damming stopper 24, the succeeding batch 8-1 is transferred to the third conveyor 22. It is dammed on the second conveyor 21 so that it will not be conveyed toward it. Subsequent batches 8-1 dammed on the second conveyor 21 have a large amount of misalignment and overlap of the objects to be conveyed 7, as shown in FIG. 13 (c).
With the subsequent batch 8-1 dammed on the second conveyor 21, the batch 8 on the third conveyor 22 is accumulated in the driving side accumulation pocket 30-1. At this time, the transfer speed V3 of the third conveyor 22 is the third conveyor fast-forward speed V31, which is higher than the normal speed V30 of the third conveyor, so that the batch 8 on the third conveyor 22 is discharged at a high speed, and the batch 8 is discharged. Can be accumulated in the driving side accumulation pocket 30-1 in a short time.

Therefore, since the subsequent batch 8-1 on the second conveyor 21 is not conveyed to the third conveyor 22, it does not mix with the discharged batch 8 on the third conveyor 22, and is set to a set number. The conveyed object 7 of N can be reliably accumulated in the driving side accumulation pocket 30-1.
Since the object to be transported 7-3 at the head of the batch 8 abuts on the damming stopper 24 for the second conveyor only once, it is possible to reduce the possibility of leaving a contact mark on the object to be transported 7.
Moreover, the transport speed V2 of the second conveyor 21 when the object to be transported 7-3 at the head of the subsequent batch 8-1 comes into contact with the damming stopper 24 is a second speed lower than the normal speed V20 of the second conveyor. Since the conveyor damming speed is V22, there is no mark of contact with the object to be transported 7. Further, since the subsequent batch 8-1 is dammed in the correct misalignment stacking posture, it can be reliably conveyed toward the third conveyor 22 when the damming stopper 24 is set to the non-damping position.

That is, when the transfer speed V2 of the second conveyor 21 remains at the normal speed V20 of the second conveyor and the conveyed object 7-3 at the head of the subsequent batch 8-1 comes into contact with the damming stopper 24, the conveyed object 7 There will be a mark of contact on -3. Further, the plurality of objects to be transported 7 on the leading side of the subsequent batch 8-1 are not displaced and overlapped, the objects to be transported 7 are turned upside down due to the impact of contact with the dam stopper 24, and the objects to be transported 7 are transferred. The misalignment overlap may be disturbed, and the misalignment stacking posture of the batch 8 may be disturbed, and even if the damming stopper 24 is set to the non-stop position, the subsequent batch 8-1 may not be able to be conveyed toward the third conveyor 22.

When the rear end of the object to be transported 7-1 at the tail of the batch 8 on the third conveyor 22 passes through the discharge side sensor 27, the batch 8 is no longer detected, and the discharge side sensor 27 does not send the detection signal to the control unit 4.
When the detection signal is no longer sent from the discharge side sensor 27, the control unit 4 determines that the third conveyor 22 has discharged the transported object. That is, the discharge side sensor 27 detects the start of discharge of the transported object 7 of the third conveyor 22 and the completion of discharge of the transported object 7.
When the detection signal of the receiving side sensor 26 is no longer transmitted, the control unit 4 repeats calculation, collation, and determination until the transport amount of the third conveyor 22 reaches a preset transport amount.

Since the first, second, and third conveyors 20, 21, and 22 are driven independently and controlled independently, the transfer amount of the third conveyor 22 is the conveyor drive system gear ratio, drive rotation speed, and time. It can be calculated by the amount of rotation calculated from each condition such as.
When the calculated transfer amount of the third conveyor 22 becomes the set transfer amount and the detection signal cannot be sent from the discharge side sensor 27, the control unit 4 collects all the objects to be transported 7 on the third conveyor 22 on the driving side. Determining that they have been integrated in the pockets 30-1, the control unit 4 starts an operation in which the integration unit 3 can start integration again, and at the same time, the transfer speed V3 of the third conveyor 22 is set to the fast forward speed V31 of the third conveyor. To the third conveyor normal speed V30. That is, the transfer speed V3 of the third conveyor 22 of the batch 8 on the third conveyor 22 from the time when the receiving side sensor 26 detects that the entire batch 8 has been conveyed to the receiving side portion of the third conveyor 22. Only until all the objects to be transported 7 are accumulated in the accumulating unit 3, the speed is switched to the third conveyor fast-forward speed V31, which is higher than the third conveyor normal speed V30.

Even if the transport amount of the third conveyor 22 calculated by the control unit 4 becomes the set transport amount, if the discharge side sensor 27 continues to send the detection signal to the control unit 4, the control unit 4 may perform the control unit 4. Even though the third conveyor 22 has conveyed only the set amount of transfer, the discharge side sensor 27 may determine that the batch 8 is in an abnormal state and warn that the state is abnormal. For example, the monitor 6 displays where an error or abnormality has occurred. Generates an audible alarm. Turn on the warning light. Combine these.
That is, the control unit 4 is on the third conveyor 22 when the calculated transfer amount of the third conveyor 22 reaches the set transfer amount, or when the discharge side sensor 27 does not send the detection signal to the control unit 4. It may be determined that all the objects to be transported 7 are accumulated in the drive side accumulation pocket 30-1, but in consideration of safety, the transfer amount of the third conveyor 22 is the set transfer amount, and the discharge side sensor 27 Since the detection signal is not sent from, it is determined that all the objects to be transported 7 on the third conveyor 22 are accumulated in the driving side accumulation pocket 30-1.

The operation of setting the stacking unit 3 into a state in which the stacking can be started again will be described.
As shown in FIG. 13 (c), the lateral movement member 53 of the lateral movement device 50 of the accumulation unit 3 is moved to the driving side, and the driving side accumulation pocket 30-1 in which the transported object 7 is accumulated is taken out on the driving side. In addition to the position, the empty operation side accumulation pocket 30-2 is set as the accumulation position. It is detected by a sensor (not shown) that the operation side accumulation pocket 30-2 has moved to the accumulation position, and is sent to the control unit 4. The control unit 4 raises the vertical movement member 41 of the vertical movement device 40 to set the operation side integrated pocket 30-2 at the set upper position. The set upper position is a position where the conveyed objects 7-3 at the head of the batch 8 discharged from the third conveyor 22 are smoothly integrated. In the embodiment, this set upper position can be set by a sensor (not shown) attached to the vertical movement device 40. That is, the vertical movement member 41 is raised, and the position where the sensor (not shown) detects the integrated pocket 30 is set to the set upper position. By changing the mounting position of the sensor, it is possible to set an appropriate upper position according to the shape, thickness, and the like of the object to be transported.

As a result, the accumulation unit 3 is in a state where the accumulation can be started again. When this operation is performed, the subsequent batch 8-1 is dammed on the second conveyor 21, and since the batch 8 does not exist on the third conveyor 22, the conveyed object is not discharged from the third conveyor 22. , The transported object will not fall to other than the collection pocket.
The object to be transported, which has been accumulated in the driving side accumulation pocket 30-1 that has moved to the removal position on the driving side, is taken out.
Since the driving side accumulation pocket 30-1 is separated from the third conveyor 22 in a direction perpendicular to the transport direction, the operation side accumulation pocket 30-2 is being taken out from the driving side accumulation pocket 30-1. Can be used to collect the items to be transported.
Therefore, the time for damming the subsequent batch 8-1 on the second conveyor 21 can be shortened, the transported and accumulated objects can be efficiently transported and accumulated, and the transported objects near the damming stopper 24 can be efficiently transported and accumulated. It is possible to prevent the amount of misalignment and overlap from becoming large and making it impossible to transport.

An example of taking out the transported object will be described.
As shown in FIG. 8, the accumulation pocket 30 has a space between the two support members 33, a vertically continuous gap between the two contact members 34, and the gap and the space are continuous.
The lower grip piece having the upper and lower grip pieces is inserted into the space, and the upper grip piece is inserted into the gap between the two contact members to grip a plurality of stacked objects to be transported. do.
The gripper is moved upward to move the plurality of objects to be transported 7 to the upper part of the accumulation pocket 30 and take them out.
The removed object is moved by the gripping tool to perform the following operation.

It is detected by a sensor (not shown) that the operation side integrated pocket 30-2 is in the upper position and sent to the control unit 4.
The control unit 4 determines that the integration unit 3 can be integrated again, and the control unit 4 moves the damming stopper 24 from the stop position to the non-stop position and sets the transfer speed V2 of the second conveyor 21 to the second. The conveyor damming speed V22 is switched to the normal conveyor speed V20. That is, the transfer speed V2 of the second conveyor 21 detects that the entire batch 8 has been transferred to the delivery side portion of the second conveyor 21 by the sensor 25, and all of the batch 8 on the third conveyor 22 have been transferred. The speed is switched to the second conveyor damming speed V22, which is lower than the normal speed V20 of the second conveyor, only until the integrated unit 3 is in a state where it can be accumulated again after the object 7 is accumulated in the accumulation unit 3.

When the damming stopper 24 is in the non-damping position, the batch 8-1 dammed on the second conveyor 21 is conveyed, passed from the second conveyor 21 to the third conveyor 22, and conveyed by the third conveyor 22. It is discharged toward the operation side accumulation pocket 30-2.
That is, from the time when the damming stopper 24 detects that the entire batch 8 has been conveyed to the receiving side portion of the third conveyor 22 by the receiving side sensor 26, all the objects to be conveyed 7 on the third conveyor 22 have been transferred. After being accumulated in the accumulating unit 3, the damming position is set only until the accumulating unit 3 is in a state where it can be integrated again, so that the damming operation is performed during that time.

As shown in FIG. 13D, when the tip of the conveyed object 7-3 at the head of the batch 8-1 reaches the discharge side sensor 27, a detection signal is sent to the control unit 4.
The control unit 4 lowers the operation-side accumulation pocket 30-2 and collects the objects to be transported in the operation-side accumulation pocket 30-2 as described above.
When the accumulation of the objects to be transported is completed in the operation-side accumulation pocket 30-2, the operation of the accumulation unit 3 so that the accumulation unit 3 can be accumulated again is started.
That is, the lateral movement member 53 of the lateral movement device 50 is moved toward the operation side, the empty driving side accumulation pocket 30-1 is moved to the accumulation position, and the operation side accumulation pocket 30 in which the transported object 7 is accumulated is accumulated. -2 is moved to the take-out position on the operation side, and the drive side accumulation pocket 30-1 is moved to the upper position.

In the integrated portion 3 of the embodiment, as shown in FIG. 6, the integrated pocket 30 moves up and down in an oblique direction with respect to the vertical direction, the front portion 30b of the integrated pocket 30 is opened, and the bottom portion 30c is horizontal. The front surface side is slanted so that it is higher toward the rear surface portion, and the rear surface portion 30d is slanted so that the upper part is away from the third conveyor 22 than the lower part. The 30c can be brought closer to the discharge side end portion 22-1a of the third conveyor 22 so that the drop distance of the transported object 7 can be remarkably shortened, and the transported object 7 discharged from the third conveyor 22 and placed on the bottom surface portion 30c can be placed on the bottom surface portion 30c. Not in a horizontal posture, but in an oblique posture in which the tip in the transport direction is lower than the rear end in the transport direction, the tip in the transport direction of the object to be transported 7 contacts the rear surface portion 30d. It can be stably accumulated without falling from 30b, and the object to be transported does not fall when the accumulation pocket 30 is moved to the take-out position.
Therefore, the objects to be conveyed discharged from the third conveyor 22 can be accurately stacked and accumulated from the bottom surface portion 30c.

The lowering operation of the accumulation pocket 30 when the object to be conveyed is conveyed and accumulated will be described.
The accumulation pocket 30 descends based on either the first descending setting (a) or the second descending setting (b).
In the first lowering setting (a), the first lowering operation and the second lowering operation are switched during the transport and accumulation operation to lower the accumulation pocket 30.
In the second lowering setting (b), the integrated pocket 30 is lowered only by the second lowering operation.
In the first lowering operation, each time the counting sensor 23 detects the conveyed object 7 while the discharge side sensor 27 detects the conveyed object 7 of the batch 8, only the preset lowering amount H is obtained. The accumulation pocket 30 during accumulation is lowered. That is, the accumulation pocket 30 at the accumulation position is lowered.

The lowering amount H in the setting of the first lowering operation is the first lowering amount H41 which is the lowering amount in the first accumulation in which the first batch 8 is accumulated when the transport accumulation operation is started, and the second and subsequent batches 8-1. It has a descent amount H42 from the second time onward, which is a descent amount in the second and subsequent accumulations. The first descent amount H41 <the second and subsequent descent amount H42.
That is, the first batch 8 is conveyed to the third conveyor 22 without being dammed by the damming stopper 24 and accumulated, but the second and subsequent batches 8-1 are dammed by the damming stopper 24 and then accumulated. As shown in FIGS. 12 and 13, the amount of misalignment and overlap of the objects to be conveyed 7 is larger in the second and subsequent batches 8-1 than in the first batch 8 because they are conveyed and accumulated on the third conveyor 22. The number of objects to be transported 7 accumulated in the accumulation pocket 30 per unit time is larger in the second and subsequent accumulations than in the first accumulation.

For this reason, in order to keep the falling distance until the transported object 7 discharged from the third conveyor 22 is accumulated in the accumulation pocket 30, the first descent amount H41 and the second and subsequent descent amounts H42 are set per unit time. It is necessary to set each according to the amount of the transported object to be accumulated.
The initial descent amount H41 is determined based on the following formula by setting the initial descent amount coefficient K41, which is a ratio of the transported object 7 to the thickness T.
H41 = T × K41
The descending amount H42 from the second time onward is determined based on the following formula by setting the descending amount coefficient K42 from the second time onward, which is a ratio of the material to be transported 7 to the thickness T.
H42 = T × K42

The first descent coefficient K41 and the second and subsequent descent coefficients K42 can be set to values in the range of 10 to 200%, and are set so that K41 <K42.
In the embodiment, K41 is set to a value in the range of 70 to 85%. That is, the initial descent amount H41 is set to a value in the range of 70% to 85% of the thickness T of the transported object 7.
In the embodiment, K42 is set to a value in the range of 80 to 105%. That is, the descending amount H42 from the second time onward is set to a value in the range of 80% to 105% of the thickness T of the transported object 7.

The second lowering operation is an operation of lowering the accumulation pocket 30 being accumulated at a lowering speed V40 corresponding to the transport speed V3 of the third conveyor 22.
The descending speed V40 is determined based on the following equation by setting the descending speed coefficient K40, which is a ratio of the third conveyor 22 to the transport speed V3.
V40 = V3 x K40
Therefore, even if the normal speed V30 of the third conveyor changes to the fast-forward speed V31 of the third conveyor during the second descent operation, the descent speed V40 also changes, so that the descent speed V40 corresponding to the transport speed V3 of the third conveyor 22 Then, the accumulation pocket 30 being accumulated can be lowered.
The descent rate coefficient K40 can be set to a value in the range of 1 to 100%, and in the embodiment, it is set to a value in the range of 20 to 30%. That is, the descending speed V40 is set to a value in the range of 20 to 30% of the transport speed V3 of the third conveyor 22.
However, the number of objects to be transported per unit time changes depending on the transfer speed V2 of the second conveyor 21, the transfer speed V3 of the third conveyor 22, etc. Since the speed V40 is different, the set values of the first descent amount coefficient K41, the second and subsequent descent amount coefficient K42, and the descent speed coefficient K40 are not limited to these values.

The operation of lowering the accumulation pocket 30 in the first lowering setting (a) during the transport and accumulation operation will be described.
Before starting the transport integration operation, the first lowering setting (a) is set in the control unit 4, the first lowering amount H41 of the first lowering operation, the second and subsequent lowering amount H42, and the lowering of the second lowering operation. The speed V40 and the thickness T of the object to be transported 7 are set in the control unit 4, respectively.
The driving side accumulation pocket 30-1 is the accumulation position, and the operation side accumulation pocket 30-2 is the operation side take-out position.
The driving side accumulation pocket 30-1, which is the accumulation position, is an upper position of the setting.

As shown in FIG. 12 (c), when the transported object 7-3 at the head of the first batch 8 reaches the discharge side sensor 27, the discharge side sensor 27 controls the detection signal. Send to 4.
The control unit 4 determines that the ejection of the batch 8 has started, and drives the vertical movement device 40 of the driving side integrated pocket 30-1 every time the detection signal of the transported object 7 is sent from the counting sensor 23. The driving side accumulation pocket 30-1 is lowered by the initial lowering amount H41. That is, while the receiving side sensor 26 and the discharging side sensor 27 detect the transported object 7, the driving side integrated pocket 30-1 is lowered by the first lowering operation.

In the first batch 8 discharged from the third conveyor 22, the headed object 7-3 is placed on the bottom surface portion 30c of the driving side accumulation pocket 30-1 and accumulated. The second transported object 7 is placed on the upper surface of the first transported object 7-3 and accumulated so as to overlap each other, and the third and subsequent transported objects 7 are also similarly integrated in the previously integrated transported object 7. It is accumulated so as to overlap the upper surface.
Therefore, if the driving side accumulation pocket 30-1 does not move up and down, the fall distance until the discharged object 7 is accumulated in the driving side accumulation pocket 30-1 is gradually shortened, but the driving side accumulation pocket 30-1 is accumulated. Since 30-1 descends for each initial descent amount H41 while the transported object 7 is falling, the falling distance until the transported object 7 is accumulated in the driving side accumulation pocket 30-1 can be made constant.

That is, the transport speed V1 of the first conveyor 20 is the normal speed V20 of the first conveyor, the transport speed V3 of the third conveyor 22 is the normal speed V30 of the third conveyor, and the object to be transported 7 is transferred from the first conveyor 20 to the second conveyor 21. The timing of passing the object 7 and the timing of discharging the object to be transported 7 from the third conveyor 22 are both at regular intervals. The driving side accumulation pocket 30-1 descends at the timing of passing the transported object 7 from the first conveyor 20 to the second conveyor 21, but by setting the initial descending amount coefficient K41 to an appropriate value, one transported object is transported. Each time is accumulated in the driving side accumulation pocket 30-1, the driving side accumulation pocket 30-1 is lowered by a distance substantially the same as the thickness T of the conveyed object, so that the next conveyed object comes first. The drop distance when the object is placed on the object to be transported and is accumulated is the same as the previous drop distance.
Therefore, the falling distance until the discharged object to be transported is accumulated in the driving side accumulation pocket 30-1 can be made constant.

As shown in FIG. 13A, when the object to be transported 7-1 at the tail of the first batch 8 is separated from the receiving side sensor 26, the control unit 4 sets the transport speed V3 of the third conveyor 22 to the normal speed V30 of the third conveyor. To the third conveyor fast-forward speed V31. At the same time, the control unit 4 descends the driving side accumulation pocket 30-1 at a descending speed V40. That is, the first descending operation is switched to the second descending operation.
Therefore, even if the third conveyor 22 is driven by the third conveyor fast-forward speed V31, which is higher than the third conveyor normal speed V30, the falling distance of the object to be transported 7 can be made constant.
That is, when the third conveyor 22 is driven at the third conveyor fast-forward speed V31, the timing of discharging the transported object is accelerated, so that the descending speed of the prime mover side integrated pocket 30-1 corresponds to the third conveyor fast-forward speed V31. By increasing the speed, the falling distance of the object to be transported 7 is kept constant.

When the discharge side sensor 27 does not detect the first batch 8 and the receiving side sensor 26 does not detect the first batch 8 and the third conveyor 22 performs the transfer operation by the set transfer amount, the control unit 4 first. It is determined that all the batches 8 of the above are accumulated in the driving side accumulation pocket 30-1, and the control unit 4 starts the operation of setting the accumulation unit 3 into a state where the integration can be started again. By the time this operation is started, the control unit 4 drives the vertical movement device 40 on the driving side to lower the driving side integrated pocket 30-1 to the lowermost position.
When the driving side accumulation pocket 30-1 is in the driving side take-out position, the operation side accumulation pocket 30-2 is in the accumulation position, and the setting is in the upper position, the accumulation unit 3 is in a state where the integration can be started again. In this state, the damming stopper 24 moves to the non-damping position, and the transport speed V2 of the second conveyor 22 switches from the second conveyor damming speed V22 to the second conveyor normal speed V20.

Subsequent batches 8-1 (hereinafter referred to as the second batch 8-1) that had been dammed on the second conveyor 22 are conveyed and passed to the third conveyor 22 for the integration operation of the second batch 8-1. Starts.
When the transported object 7-3 at the head of the second batch 8-1 reaches the discharge side sensor 27, the operation side integrated pocket 30-2 is the second time every time the counting sensor 23 detects the transported object 7. After that, it descends by the descending amount H42 (first descending operation). When the object to be transported 7-1 at the tail of the second batch 8-1 is separated from the receiving side sensor 26 and the transport speed V3 of the third conveyor 22 is switched to the third conveyor fast-forward speed V31, the operation side integrated pocket 30- 2 descends at a descending speed V40 (second descending operation).
That is, the integration operation of the second batch 8-1 is the same as the integration operation of the first batch 8, except that the lowering amount (H) of the first lowering operation is large.

When the accumulation of the second batch 8-1 is completed, the accumulation unit 3 starts the operation of making the accumulation start again. The operation-side accumulation pocket 30-2, which stacks and accumulates a plurality of objects 7 to be transported in the second batch 8-1, is moved to the operation-side take-out position, and the empty prime mover-side accumulation pocket 30-1 is integrated. By moving to a position and moving to an upper position of the setting in order to determine one condition for starting the accumulation, the accumulation unit 3 is in the state of starting the accumulation. This operation is performed by a command of the control unit 4 based on the detection of each sensor.
The third and subsequent batches are accumulated in the same manner as the second batch 8-1, and the driving side accumulation pocket 30-1 and the operation side accumulation pocket 30-2 are alternately moved to the accumulation position and the take-out position.
Since it is necessary to shorten the one-cycle time as much as possible in the integrated unit 3 described above in order to improve the efficiency, it is preferable to shorten the one-cycle time as follows. For example, when the accumulation pocket 30 at the take-out position moves to the accumulation position, or while the position is detected and the timer is set to rise to the upper position of the setting, the accumulation is started, that is, the dam is stopped. The batch 8 is released and moved onto the third conveyor 22. However, it is necessary to have the discharge side sensor 27 detect and determine that the integrated pocket 30 has reached the upper position of the setting before the batch 8 arrives.
Therefore, it is possible to shorten the waiting time from when the accumulation pocket 30 reaches the upper position of the setting until the batch 8 to be opened starts to accumulate, so that one cycle time can be shortened.

When the transport and accumulation operation is completed, the object to be transported 7 is not supplied from the supply unit 1 to the first conveyor 20, and the counting sensor 23 does not detect the object to be transported 7, so that the collection pocket 30 is first lowered. It becomes impossible to descend due to movement.
Therefore, when the counting sensor 23 descends the integrated pocket 30 in the first descending operation without detecting the object 7 to be transported, it is switched to descend in the second descending operation and descends at the descending speed V40.
For example, when the detection signal cannot be sent from the counting sensor 23 to the control unit 4 while the integrated pocket 30 is being lowered in the first lowering operation, the control unit 4 lowers the integrated pocket 30 at the lowering speed V40. When the discharge side sensor 27 detects the conveyed object 7-3 at the head of the batch 8 passed to the third conveyor 22 in a state where the detection signal is not sent from the counting sensor 23 to the control unit 4, the control unit 4 Descends the accumulation pocket 30 at a descending speed V40.

The control unit 4 determines that the discharge of the first batch 8 has started, and descends at the descending speed V40 set for the driving side accumulation pocket 30-1.
When the discharge side sensor 27 does not detect the first batch 8 and the receiving side sensor 26 does not detect the first batch 8 and the third conveyor 22 performs the transfer operation by the set transfer amount, the control unit 4 first. It is determined that all the batches 8 of the above are accumulated in the prime mover side accumulation pocket 30-1, and the control unit 4 starts the operation of putting the accumulation unit 3 into a state where the integration can be started again. At the same time as this operation, the control unit 4 drives the vertical movement device 40 on the driving side to lower the driving side integrated pocket 30-1 to the lowermost position.

When the driving side accumulation pocket 30-1 in which a plurality of objects to be transported 7 are stacked and accumulated is in the driving side take-out position, the empty operation side accumulation pocket 30-2 is in the accumulation position, and is in the upper position of the setting. The accumulation unit 3 is in a state where accumulation can be started again. In this state, the damming stopper 24 moves to the non-damping position, and the transport speed V2 of the second conveyor 22 switches from the second conveyor damming speed V22 to the second conveyor normal speed V20.
The second batch 8-1 dammed on the second conveyor 21 is conveyed, passed to the third conveyor 22, and the integration operation of the second batch 8-1 starts.
The integration operation of the second batch 8-1 is the same as that of the first batch 8, and the operation side accumulation pocket 30-2 is descended at the set descending speed V40.

When the accumulation of the second batch 8-1 is completed, the accumulation unit 3 starts the operation of making the accumulation start again. The operation side accumulation pocket 30-2, which stacks and accumulates the plurality of objects 7 of the second batch 8-1, is moved to the operation side take-out position, and the empty prime mover side accumulation pocket 30-1 is the accumulation position. By moving to the position above the setting and moving to the upper position of the setting, the collecting unit 3 is in a state of starting to collect. This operation is performed by a command of the control unit 4 based on the detection of each sensor.

In this case, the first descent amount H41 of the first descent operation, the descent amount H42 of the second and subsequent descent operations, the descent speed V40 of the second descent operation, and the thickness T of the transported object 7 are set in the control unit 4, respectively. ..
