The temporary receiving member 39 temporarily receives the product.

  The transport stacking device (alignment stacking device 5) described in Patent Document 1 stacks the pouches sent from the upstream conveyor (transport line) on the cradle at the stacking position, then pushes the cradle down to the transport position. Then, the pouches stacked on the pedestal by the push-out plate are pushed from the side to be moved to the downstream side conveyor (first horizontal feed conveyor 8) of the lateral feeding device 6, and the stacked pouches are conveyed to the binding machine 7. .

5 and 6 are also known as a transport stacking device having a stacking unit that stacks the pouches transported from the upstream conveyor of the bag making device and transports the pouches to the next step.
The stacking section 210 of the known transport stacking apparatus 200 receives a receiving table 211 configured to be movable up and down, a holding section 212 for aligning the pouches P stacked on the receiving table 211, and a pouch P stacked on the receiving table 211. It has a transport unit 220 for transporting to the next process, and a temporary receiving member 216 for accumulating the pouches P instead of the pedestal 211 while the receiving table 211 transfers the pouch P to the transporting unit 220.

The holding part 212 has an aligning hand 213 configured to be able to move forward and backward from the side of the pouches P accumulated on the pedestal 211, and an abutting wall part arranged to face the aligning hand 213 with the pedestal 211 interposed therebetween. 215 is provided, and a comb-shaped contact comb portion 214 that opens downward is provided at the end of the alignment hand 213 on the butting wall portion 215 side so as to face the butting wall portion 215.

Japanese Patent No. 2958763

  However, there is still room for improvement in these known transporting and accumulating devices.

That is, in the transport stacking apparatus 200 known in the patent documents and the like, as shown in FIGS. 11 and 12, the error pouch PS is caught on the butting wall portion 215 and is not normally stacked (hereinafter, referred to as “abnormal stacking”). .) Is rare, and when the conveyed items have a certain thickness and hardness, such as corrugated cardboard, the conveyed items are stuttered even if abnormal accumulation occurs, and the upstream conveyed items are blocked. Therefore, the abnormal accumulation can be detected immediately. However, when the thin and easily deformed conveyed objects such as pouches are accumulated, when the abnormal accumulation occurs, as shown in FIGS. The pouch P sent from the conveyor C pushes up the error pouch PS from the side, and the error pouch PS is accumulated in a state in which the front and back are reversed, and abnormal accumulation is not detected and the accumulation work is continued. There was a fear that is.
Due to this, there is a possibility that trouble may occur in the work to be performed in the next process, such as a defective printing position such as a lot number, or a visual inspection of all the front and back surfaces of the pouches that have been accumulated, resulting in a large increase in the work amount. There is a risk that the working cost will increase significantly, and that the production line for the pouch, the production line for filling the pouch with the product, and the like will be stopped for a long time.
A method of monitoring the pouch stacking status of the stacking unit 211 using a sensor or the like from above the stacked pouches P or from the front direction without the alignment hand 213 is also conceivable, but it is monitored from above the stacking unit. In that case, there is a risk that the sensor may erroneously detect the accumulation status due to the reflection of the illumination or the like on the accumulated pouch due to the material of the pouch or the state of the pouch surface, and when monitoring from the front direction of the accumulation part, the error pouch PS Since the surface cannot be captured, the sensor or the like may not be able to detect the error pouch PS.

  The present invention is to solve these problems, with a simple configuration, even when accumulating thin and easily deformable pouches and the like, abnormal accumulation can be quickly detected, and the inspection time of the accumulated pouches can be shortened. An object of the present invention is to provide a transport and stacking device that can reduce the number of times and reduce the time required for restarting the production line.

  The transport stacking device of the present invention is a transport stacking device having a stacking unit that stacks the pouches transported from the upstream conveyor of the bag making device and transports the pouch to the next step, wherein the transport stacking device detects the pouch. The stacking unit further includes a receiving unit configured to be movable up and down, and a holding unit that aligns the pouches stacked on the receiving unit, and the holding unit is stacked on the receiving unit. An aligning hand configured to be movable back and forth from the side of the pouch, and an abutting wall portion arranged to face the aligning hand with the pedestal interposed therebetween are provided, and the abutting wall of the aligning hand is provided. A comb-shaped contact comb portion opened downward is provided at the end on the side facing the abutting wall portion, and the detection unit detects from the opposite side of the stacking unit with the contact comb portion as a boundary. It is possible to solve the above-mentioned problems. It is intended.

The transport stacking device of the invention according to claim 1 has a detection part for detecting a pouch, and the detection part is a stacking part with a contact comb part provided at an end of the alignment hand on the butting wall side as a boundary. Since it can be detected from the opposite side, an error pouch that is a source of abnormal accumulation can be detected without the detection unit coming into contact with the pouch or hindering the operation of the accumulation unit.
Further, since the detection unit detects the pouch from the opposite side of the stacking unit with the contact comb portion provided at the end of the abutting wall of the alignment hand as a boundary, it is possible to reliably secure the space necessary for installing the detection unit. Since the surface of the error pouch can be captured, the detection unit can reliably detect the error pouch.

According to the configuration of claim 2, the detection unit is configured by a laser sensor, and the laser sensor is arranged at a position where the irradiation light emitted from the laser sensor can pass through the gap of the contact comb portion. The laser sensor does not need to be installed in any place as long as it can pass the irradiation light through the gap between the contact combs, and the laser sensor can read the reflection status of the irradiation light so that the pouch can be integrated even in an environment such as a dark room where visible light is scarce It is possible to confirm the accumulation state in the section and detect the abnormal accumulation more reliably.
According to the configuration of claim 3, since the laser sensor includes the retroreflective laser sensor and the retroreflective mirror, the retroreflective laser is retroreflected by the laser applied to the retroreflective mirror. If the pouch stacking part is located between the retroreflective laser sensor and the retroreflective mirror by using the property of detecting only objects, the pouch stacking part will not be disturbed by ambient light. The accumulation state can be confirmed, erroneous detection can be prevented, and abnormal accumulation can be detected more reliably.

According to the configuration of claim 4, further comprising a stacking confirmation means for determining the normal stacking on the stacking portion based on the signal of the detection portion, so that the stacking confirmation means can perform the stacking state of the pouches without the operation of a worker. Can be detected automatically and quickly.
According to the configuration of claim 5, since the stacking confirmation unit has a state determination unit that determines whether or not there is abnormal stacking of the pouch based on the information on the stacking state of the pouch acquired from the detection unit, By cooperating with the state determination unit, it is possible to quickly and automatically determine whether or not there is an abnormal accumulation of pouches, without intervention by a worker.

According to the configuration of claim 6, the stacking confirmation means is a device for activating or stopping the bag making device and the transport stacking device based on the determination information on the presence / absence of abnormal stacking of the pouch acquired from the state determination unit. Since it has a stop part, by coordinating the state determination part and the device stop part, when abnormal accumulation of pouches occurs, the bag making device and the conveying and accumulating device can be swiftly and reliably operated without the operation of a worker. It can be stopped automatically.
Furthermore, since the time from the determination of abnormal accumulation to the stop of the transport accumulating device can be shortened, other pouches accumulated on the pouch in which abnormal accumulation has occurred can be minimized, and inspection of accumulated pouches can be performed. The time required for the work is reduced, and the time until the bag making device and the transport and stacking device are restarted can be shortened.
According to the configuration of claim 7, since the stacking confirmation unit has the transfer confirmation unit that acquires the transfer timing of the pouch, the transfer confirmation unit and the detection unit are linked to each other, so that the pouches can be collected during normal stacking. The detection unit can be operated only at the completion timing, and energy can be saved by shortening the operation time of the detection unit.
Further, by linking the transfer confirmation unit and the state determination unit, or by linking the transfer confirmation unit and the device stop unit, it is possible to determine whether or not there is an abnormal accumulation of pouches in the pouch accumulation state information acquired by the detection unit. It is also possible to operate the state determination unit only at the timing when the determinable information can be acquired, or to activate the device stop unit only at the timing when the determination information about the presence or absence of abnormal accumulation by the state determination unit can be acquired. Energy saving can be further achieved by shortening the operating time of the stop portion.

A transport stacking apparatus 100 according to an embodiment of the present invention has a stacking unit 110 that stacks the pouches P transported from the upstream conveyor C of a bag making apparatus (not shown) and transports the pouches P to the next step. As shown in FIG. 1, the transport stacking apparatus 100 has a detection unit configured by a pair of recursive reflection type laser sensors 130 and a recursive reflection type mirror 131 capable of determining the normal accumulation of the pouch P on the stacking unit 110. ing.
The stacking unit 110 includes a pedestal 111 configured to be movable up and down, a holding unit 112 that aligns the pouches P stacked on the pedestal 111, and a transport unit 120 that receives the pouches P stacked on the pedestal 111 and transports them to the next process. And a temporary receiving member 116 for accumulating the pouches P instead of the receiving table 111 while the receiving table 111 is transferring the pouches P to the transport section 120.

The holding part 112 has an aligning hand 113 configured to be able to move forward and backward from the side of the pouches P accumulated on the pedestal 111, and an abutting wall part arranged to face the aligning hand 113 with the pedestal 111 interposed therebetween. 115 is provided, and a comb-shaped contact comb portion 114 opened downward is provided at the end of the alignment hand 113 on the butting wall portion 115 side so as to face the butting wall portion 115. .
The transfer unit 120 includes a transfer member 121 that receives the pouches P accumulated on the receiving table 111, a downstream conveyor 123 that receives the pouch P from the transfer member 121 and transfers the pouch P to the next process, and a pouch P that is placed on the transfer member 121 downstream. A counter plate 122 is provided on the side conveyor 123.

The pedestal 111 is configured to be vertically movable so that the pouches P conveyed from the upstream conveyor C are always stacked at the stacking height H, so that the pouches from the upstream conveyor C to the pedestal 111 are stacked. The behavior of P can be stabilized.
The pedestal 111 has a groove that is open to the lower side and the side to allow the contact comb 114 to pass therethrough, and finely moves back and forth toward the pouch P while allowing the contact comb 114 to pass through the groove of the pedestal 111. By doing so, all the pouches P accumulated on the pedestal 111 can be reliably sandwiched between the abutting wall portions 115 and aligned.

Since the temporary receiving member 116 is formed in a comb shape that can pass through the contact comb portion 114, the temporary receiving member 116 passes through the contact comb portion 114 and accumulates while the receiving table 111 transfers the pouch P to the transfer member 121. It moves to the height H and collects the pouches P instead of the pedestal 111.
Since the transfer member 121 is formed in a comb shape that can pass through the groove of the pedestal 111, after the transfer member 121 has passed through the groove of the pedestal 111 from the side, the pedestal 111 descends and the transfer member 121. By moving the pouch P relatively upward, the pouches P accumulated on the pedestal 111 can be transferred to the transfer member 121.

The counter plate 122 is provided on the opposite side of the pedestal 111 with the center of the downstream conveyor 123 interposed therebetween, and the lower part of the counter plate 122 is formed in a comb shape through which the transfer member 121 can pass.
As a result, when the transfer member 121 that receives the pouches P accumulated from the receiving table 111 passes over the downstream side conveyor 123 and passes under the counter plate 122, the counter plate 122 relatively transfers the accumulated pouches P. By pushing out from above the member 121, the accumulated pouches P can be transferred to the downstream side conveyor 123.

The retroreflective laser sensor 130 is provided on the upper surface of the counter plate 122, and the transmitter / receiver section of the irradiation laser L is installed above the integrated height H and in a direction facing the abutting wall 115.
Further, the retroreflective mirror 131 is installed on the butting wall 115 at a position where the irradiation laser L emitted from the retroreflective laser sensor 130 can be reflected by the transmitting / receiving section of the retroreflective laser sensor 130.

  At this time, the retroreflective laser sensor 130 is installed on the counter plate 122 side by installing the transmitting / receiving unit of the retroreflective laser sensor 130 at a position where the irradiation laser L can pass through the gap of the contact comb 114. Also, the recursive reflection type mirror 131 can be irradiated with the irradiation laser L through the contact comb portion 114, and the recursive reflection type laser sensor 130 can receive the irradiation laser L reflected by the recursive reflection type mirror 131.

In addition to the above configuration, although not shown for the sake of explanation, as the configuration of the transport stacking apparatus 100, a detection unit, a transport confirmation unit that acquires the transport timing of the pouch P transported from a bag making machine (not shown), and a pouch. A stacking confirmation unit having a state determination unit that determines whether P is abnormally stacked and a device stop unit that operates or stops the bag making device (not shown) and the transport stacking device 100 is provided.
In addition, the stacking confirmation unit is configured to be capable of transmitting the transport timing information of the pouch P acquired by the transport confirmation unit to the detection unit, and also transmits the stacking state information of the pouch P acquired by the detection unit to the state determination unit. It is configured to be capable of transmitting the information on the presence / absence of abnormal accumulation of the pouches P acquired by the state determination unit to the device stopping unit.

Next, the procedure and operation of the normal stacking determination and the abnormal stacking determination of the pouches P stacked on the receiving table 111 of the transport stacking apparatus 100 of the present invention will be described with reference to FIGS. 3 and 4.
First, the receiving table 111 is moved up and down according to the stacking height H to prepare for stacking the pouches P conveyed from the upstream conveyor C.

Next, the transport confirmation unit determines the transport timing of the pouches P that are transported intermittently from the upstream side of the bag manufacturing apparatus (not shown) at a constant interval before the pouches P are stacked on the receiving table 111. Start reading.
The stacking confirmation unit transmits the information on the transport timing of the pouch P acquired by the transport confirmation unit to the detection unit, and the detection unit calculates the stacking timing of the pouch P on the pedestal 111 based on the transport timing of the pouch P. , The irradiation laser L is emitted from the retroreflective laser sensor 130 at the integration timing of the pouch P.

When the pouches P are normally accumulated, as shown in FIG. 3, the irradiation laser L passing through the gap of the contact comb portion 114 is retroreflected by the retroreflective mirror 131, and then transmitted / received by the retroreflective laser sensor 130. Return to section.
The accumulation confirmation unit transmits, to the state determination unit, information that the retroreflective laser sensor 130 has received the irradiation laser beam L that has been retroreflected from the detection unit.

Next, the state determination unit determines that the pouch P is accumulated on the pedestal 111 normally based on the reception information of the irradiation laser received from the detection unit via the accumulation confirmation unit.
The stacking confirmation means transmits, to the device stopping unit, information indicating that the stacking of the pouches P on the pedestal 111 is normally performed from the state determination unit.
The device stopping unit instructs the bag making device (not shown) and the transport stacking device 100 to continue the operation based on the information on the normal stacking of the pouches P received from the state determination unit via the stacking confirmation unit. .

On the other hand, when abnormal accumulation occurs, as shown in FIG. 4, the abnormally accumulated error pouch PS is positioned so as to be caught by the butting wall portion 115 and hides the retroreflective mirror 131.
As a result, the irradiation laser L emitted from the retroreflective laser sensor 130 cannot reach the retroreflective mirror 131 and is diffused by hitting the error pouch PS. The detection unit does not return the information that the retroreflective laser sensor 130 could not receive the irradiation laser L retroreflected by the retroreflective mirror 131 at the integration timing of the pouch P via the integration confirmation means. Send to the judgment section.

The state determination unit determines, based on the information received from the detection unit via the accumulation confirmation unit, that an abnormality has occurred in the accumulation of the error pouch PS on the pedestal 111, and the device is confirmed via the accumulation confirmation unit. Send judgment information to the stop.
The device stopping unit instructs the bag making device (not shown) and the transport stacking device 100 to stop the operation based on the information on the abnormal stacking of the error pouch PS acquired from the state determining unit via the stacking confirmation unit. To do.

After stopping the bag making device (not shown) and the transport stacking device 100, the error pouch PS in which abnormal stacking has occurred, and the stacking state of the pouches P stacked on the pedestal 111 immediately before stacking the error pouch PS are displayed. Check and eliminate defects.
As a result, the time until the bag making apparatus (not shown) and the transport stacking apparatus 100 are restarted is significantly shortened as compared with the case where the transport stacking apparatus 100 is operated while the error pouches PS are abnormally stacked. Therefore, the collecting work can be carried out quickly.
Further, since the location where the error pouch PS is abnormally accumulated is clearly known, it is possible to reduce the work cost required for checking the abnormally accumulated error pouch PS and returning it to the normal state.

When the surface of the pouch P is processed to have a mirror surface, the irradiation laser L is held even if the error pouch PS is held vertically as viewed from the pedestal 111 and faces the retroreflective laser sensor 130. Is reflected by the error pouch PS and returns to the transmitter / receiver of the retroreflective laser sensor 130, but since it is different from the retroreflected irradiation laser L, it is not erroneously detected as a normal integrated state.
When the pouch P is made of a transparent material, the irradiation laser L passes through the error pouch PS and reaches the retroreflective mirror 131, and the retroreflected irradiation laser L passes through the error pouch PS again. Although it may return to the transmitter / receiver of the retroreflective laser sensor 130, the phase of the irradiation laser L changes when passing through the error pouch PS, so that it is not erroneously detected as a normal integrated state.
Further, even when the pouches P are accumulated on the temporary receiving member 116, the method for confirming the accumulation of the pouches P by the accumulation confirmation means is the same as that for accumulating the pouches P on the receiving table 111.
