Description

  In the present invention, the folded one-touch carton is pulled out from the upstream conveyor one by one by the curved surface of the lifting guide, and the lock-shaped structure formed at the bottom of the carton is automatically combined and locked. It relates to a box device. In particular, there is a low probability that the lock will be executed with high reliability, and there is a low probability that the transfer of the carton to the downstream conveyor will stop due to the lock failure of the transfer, and a system configuration that can efficiently fill the contents can be achieved. Relates to the device.

  Regarding the configuration in which the carton is pulled out from the upstream conveyor and opened, it was as follows. That is, the means for pulling out the cartons is to take out the cartons in the carton magazine one by one and take out one side of the front surface while taking it out, and open it while bringing the curved surface of the fixing guide for contact with the other side surface of the front surface, It was whether the carton was adsorbed and opened so as to be separated from the side surfaces on both sides of the carton.

  However, the above means often caused a carton error and a lock failure. Due to this defect, the carton transfer system of the downstream conveyor is stopped, and the workability is deteriorated because the stop time becomes longer.

Therefore, in Patent Document 1, in addition to the above system, the system further includes a sensor that detects whether or not the box is opened, and the idea is not to pass the boxing carton to the downstream conveyor. In addition, this system is provided with a lifting assist means for preventing the carton that has been lifted from returning to its original state due to elasticity by being attracted and pulled away from the front and back by a robot hand with a robot hand. I was sure to open it. (Patent Document 1, paragraph 0015, FIG. 11)

  Patent Document 2 discloses an apparatus that reliably opens the sheet so as not to cause reverse folding in consideration of the above problems.

  Here, the details of the opening in the one-touch carton are described below. One-touch carton sucks the first side of one plane folded into the front and back two sheet-shaped planes with a vacuum pad, etc., and the adjacent second side of the plane in the same direction When the first side surface is gradually pulled out while contacting the curved surface, the angle between the first side surface and the second side surface approaches 180 degrees to 90 degrees, the carton is opened, and the bottom surface portion is shown in FIG. As shown to a), it becomes a square shape.

  When the one-touch carton is in the above-described state, the bottom-shaped portion is automatically formed by combining the bottom-lock structure.

  However, when the lock shape of the bottom of the one-touch carton as shown in FIG. 3A is a lock type, it is a stable structure that is difficult to release if locked, but is difficult to lock.

  Accordingly, in the hoisting device using the one-touch carton having a key-type structure that is difficult to lock, the flow to the downstream conveyor stops due to the occurrence of locking failure, and a lot of time is spent. Therefore, there has been a demand for a highly reliable hoisting device that is compatible with a one-touch carton at the bottom of a key type that is difficult to unlock, and that secures locking.

Japanese Patent Laid-Open No. 11-11480 (pages 2, 3 and 1) Japanese Patent Laid-Open No. 2002-96404 (pages 2, 3 and 1)

  An object of the present invention is to provide a hoisting device that solves the above-described problems even in a one-touch carton having a key-type bottom structure.

  That is, the first side surface of one of the folded one-touch cartons is sucked and pulled out with a vacuum pad, and the adjacent second side surface on the same surface side is raised while the first side surface is adsorbed. While abutting on the curved surface of the box fixing guide, the bottom surface of the carton is rectangular, combined with a key-shaped lock shape, and in order to secure the lock, a force for pushing the bottom of the second side is given, An object is to provide a hoisting device that gives a force to push the upper portion of the second side surface immediately after that, and has high reliability and no lock failure even with a key-type lock.

In order to solve the above-mentioned problems, the one-touch carton hoisting device of the present invention receives one-touch cartons folded from an upstream conveyor one by one and sucks the first side surface of the one-touch carton surface dropped into the carton stocker. The bottom of the one-touch carton is constructed by sliding the one-side carton while pulling out the carton while bringing the second side surface adjacent to the suction surface into contact with the curved surface of the fixing guide for hoisting. In the hoisting device in which the lock-shaped structure is automatically combined and locked to form the bottom surface part and transferred to the downstream conveyor,
A set of vacuum pads that are sucked and released by turning the vacuum valve ON / OFF by a pad suction / release control signal at a plurality of positions near the bottom surface of the first side surface of the one-touch carton that has entered the carton stocker; ,
A gate opening / closing mechanism that includes a gate member in the stocker to turn on / off the air cylinder in response to a gate opening / closing control signal to store / take out the carton in order to securely store / take out the one-touch carton that has entered the stocker.
An actuator that is mounted with the vacuum pad and moves in one of the horizontal directions based on a movement control signal, and a carton adsorbed by driving the actuator is pulled out from the stocker, and the second side is a curved surface of the fixed guide for opening A slide movement mechanism comprising a slide member having a stroke length to a predetermined position where the bottom surface portion is gradually opened to a rectangular shape while being in contact with
When the carton is pulled out to the predetermined position and the first side face bottom is adsorbed by a vacuum pad, and further, a force is applied to push the second side bottom so as to secure the carton bottom lock. A bottom hoisting mechanism comprising a bottom hoisting guide and an air cylinder driven by a bottom hoisting control signal to rotationally drive the bottom hoisting guide;
Immediately after the bottom of the second side of the carton is pushed in, the upper hoisting guide for pushing in the upper part of the second side and the upper hoisting control signal for rotating the upper hoisting guide are driven. An upper opening mechanism composed of a vacuum valve,
The current position of the carton is input by a sensor, and the pad adsorption / release control, gate opening / closing control, pad movement control, bottom hoisting control, and upper hoisting control for controlling the next state corresponding to the carton at a predetermined timing. And a controller for outputting.

In the initial state, the control unit sends a gate closing signal as a gate control signal to the gate opening / closing mechanism, sends a pad release signal to the vacuum pad, and sets the pad moving mechanism at a predetermined position. A control signal is sent, and a signal is sent to the bottom and top lifting mechanisms so that the air cylinder of the mechanism is turned off,
In this state, the control unit sends a control signal to the pad moving mechanism if it determines that the carton has fallen into the carton stocker, and if it determines via the sensor that the vacuum pad has contacted the carton, If an adsorption signal is sent to the pad and the carton is adsorbed, and it is determined via the sensor that the carton has been adsorbed, a control signal is sent to the pad moving mechanism and the carton is pulled out to a predetermined position. When the determination is made, each means is provided with means for sending a bottom and top raising control signal to give a force to push the bottom and top of the carton into the bottom and top so as to secure the bottom lock.

  The present invention has the following effects. That is, even if the one-touch carton bottom is a key-shaped one-touch carton that is difficult to lock, the hoisting device does not have a lock failure.

  Therefore, the system configuration in which the carton using the hoisting device is filled with the contents can eliminate the problem that the automation operation is interrupted due to a lock failure.

  Embodiments of the one-touch carton hoisting device of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a plan view of a one-touch carton hoisting device, and FIG. 2 is a front view thereof. 3A and 3B show the structure of the one-touch carton, where FIG. 3A is a bottom view, FIG. 3B is a side view, and FIG. 3C is a folded state.

  1 and 2, reference numeral 1 denotes a folded one-touch carton. As shown in FIG. 3C, the four-direction side surfaces are folded in two on the front and back sides. 2 shows the one-touch carton in the opened state in which the one-touch carton is opened and the bottom surface has a square shape as shown in FIGS. 3 (a) and 3 (b).

  FIG. 3A shows a bottom portion of the one-touch carton, and 3 is a bottom lock portion. In FIG. 3B, 4 is a lid, 5 is a first side surface, 6 is a second side surface, 7 is a bottom portion of the opened carton, and 8 is an upper portion of the carton.

  In the state where the one-touch carton shown in FIG. 3C is folded, the structure of the bottom surface portion of the bottom surface lock portion 3 is folded inside the fold.

  1 and 2, the left side is an upstream conveyor 100 on which the folded one-touch carton 1 is placed. 100d indicates the end of the rotating belt. One-touch cartons 1 are placed at predetermined intervals between separator members 9 that are arranged at predetermined intervals and move with the upstream conveyor 100.

  Reference numeral 25 denotes a carton stocker. In order to take out one carton 1 from the upstream conveyor 100 one by one, the front surface of the one-touch carton 1 is adsorbed by a vacuum pad 90c, and then a control signal for taking out the carton is sent from the control unit 60 to the air cylinder 90a. Then, the one-touch carton 1 is raised and the slide member 90b moves the one-touch carton 1 directly above the carton stocker 25 by the control signal from the control unit 60 to turn off the suction of the vacuum pad 90c to the carton stocker 25. Drop 1 (See Figure 2)

The gate member 30b is pushed down from the carton stocker 25 so that the one-touch carton 1 does not fall outward from the opening side of the carton stocker 25. (See Figure 1)
The gate member 30b moves up and down by a control signal to the gate opening / closing air cylinder 30a. If moved downward, the one-touch carton 1 does not come out of the carton stocker 25.

  FIG. 1 shows a state where the one-touch carton 1 in which the vacuum pad 20c for opening (a plurality, two sets in this embodiment) is folded in the above state is adsorbed.

  The hoisting vacuum pad 20 c is attached to the tip of the pad moving mechanism 20. FIG. 1 also shows a state where the pad moving mechanism 20 moves to the left by a predetermined stroke length and the one-touch carton 2 is opened.

  The following describes how the one-touch carton 1 opens.

  There are two side surfaces on one front surface of the folded one-touch carton 1, which is composed of a first side surface 5 and a second side surface 6. The hoisting vacuum pad 20 c attracts the first side surface 5 and moves to the right by the pad moving mechanism 20. The second side surface 6 also moves to the right as it moves. However, since the second side surface 6 is not adsorbed, the second side surface 6 moves along the hoisting fixing guide 15 as the first side surface 5 moves. That is, the angle formed between the first side surface 5 and the second side surface 6 gradually approaches 90 degrees from 90 degrees, and the one-touch carton 2 is opened at the predetermined position illustrated in FIGS. 1 and 2.

  The pad moving mechanism 20 includes a slide member 20b and an actuator 20a controlled by the control unit 60.

  As described above, even when the one-touch carton 2 is opened at a predetermined position, the bottom surface lock portion 3 formed on the bottom surface of the carton may not be completely locked, that is, the lock may be incomplete. In particular, when the lock structure is a key type, the probability of being incomplete increases.

  If the carton is placed on the downstream conveyor 200 in an incompletely locked state, the carton may be unlocked, or the contents may not enter or go out, and may be detected by a sensor to stop the system. Become.

  Therefore, the present invention includes a bottom hoisting mechanism 40 and an upper hoisting mechanism 50 as shown in FIGS.

  The bottom hoisting mechanism 40 includes an air cylinder 40a and a bottom hoisting guide 40b attached to the air cylinder 40a.

  The control signal sent from the control unit 60 to the air cylinder 40a causes the cylinder of the air cylinder 40a to move back and forth, and the bottom hoisting guide 40b pushes into the bottom of the second side surface 6 of the opened one-touch carton 2. give. Thereby, when the key-shaped engagement is formed incompletely, this can be corrected. Reference numeral 40d denotes a fulcrum of the bottom hoisting guide 40b.

  On the other hand, the upper hoisting mechanism 50 includes an air cylinder 50a and an upper hoisting guide 50b attached to the air cylinder 50a.

  Following the control signal sent from the control unit to the air cylinder 40a, the control signal is also sent to the air cylinder 50a. By the control signal, the cylinder of the air cylinder 50 a moves back and forth, and the upper hoisting guide 50 b gives a force to push into the upper portion of the second side surface 6. This corrects the key-type incomplete formation. By this operation, there is no lock failure and the probability of work line stoppage can be further reduced. Reference numeral 50d denotes a fulcrum of the upper hoisting guide 50b.

  As described above, the one-touch carton 2 having the bottom formed completely by the key shape is dropped onto the downstream conveyor 200 and placed on the content insertion conveyor of the next step.

  1 and 2, reference numeral 60 denotes a control unit, and the positions of the one-touch cartons 1 and 2 in the upstream conveyor 100, the pad moving mechanism 20, the gate opening / closing mechanism 30, the bottom hoisting mechanism 40, and the upper hoisting mechanism 50. The external information input terminal 60a that receives a reception signal from various sensors that detect the signal and sends it to the CPU via the I / F, the external information is judged by the CPU, and the various mechanisms 20, 30, A control signal output terminal 60b for transmitting a control signal to the 40 and 50 via the I / F is provided. FIG. 10 shows an example of the control unit 60.

  4-9 is explanatory drawing of the operation | movement order of a boxing apparatus. Each stage of operation sequence (1) to (6) is shown.

  Here, the control unit 60 immediately before starting the operation is initialized at least as follows. In the control unit 60 shown in FIG. 10, the gate control signal to the gate opening / closing mechanism 30 in the initial state is sent to the gate opening / closing air cylinder 30a, and the gate member 30b is closed.

  In addition, a pad release signal is sent to the hoisting vacuum pad 20c attached to the tip of the pad moving mechanism 20, and a control signal is sent so that the pad moving mechanism 20 enters a waiting state at a predetermined position. ing. That is, as shown in FIG. 1, it waits in the position used as the stroke length until it is pulled out by the vacuum pad 20c for boxing, and a bottom part lock | rock part becomes square shape.

  The bottom hoisting mechanism 40 and the upper hoisting mechanism 50 are supplied with control signals for turning off the air cylinders 40a and 50a, respectively.

  In the above initial state, the CPU waits for the one-touch carton 1 to be dropped and accommodated in the carton stocker 25. When the one-touch carton falls, a sensor signal for detecting the one-touch carton is input from the external information input terminal 60a, and the input signal is determined by the CPU through the I / F. The CPU reads out the determination results and programs of various means that are predetermined and written in the storage device 60c, and the CPU outputs a control signal from the control signal output terminal 60b to the pad moving mechanism 20 via the I / F. The hoisting vacuum pad 20 c is moved and pressed against the one-touch carton 1 in the carton stocker 25. Further, a suction control signal is sent to suck the vacuum pad 20c for opening. This state is shown in the operation sequence (1) in FIG.

  FIG. 5 shows the next operation sequence (2) in which the gate member 30b is opened and the hoisting vacuum pad 20c is pulled and raised.

  Following the operation sequence (1) in FIG. 4, the CPU sends a control signal for returning the vacuum pad 20c for opening to the original position (predetermined position) from the control signal output terminal 60b to the pad moving mechanism 20, and to the gate member 30b. Send a control signal to open the gate.

  FIG. 5 shows a state in the middle where the carton has not reached the predetermined position. The one-touch carton 1 shows a state in the middle of opening from a folded state. That is, in this figure, the angle formed by the first side surface 5 and the second side surface 6 is between 180 degrees and 90 degrees.

  In this state, the second side face 6 is gradually inclined in the horizontal direction in contact with the curved surface of the lifting guide 15.

  FIG. 6 shows the next operation sequence (3): the opening vacuum pad 20c is stopped at a predetermined position where the one-touch carton is square (rectangular).

  Here, the angle formed by the first side surface 5 and the second side surface 6 of the one-touch carton 2 is 90 degrees and the vehicle stops at a predetermined position. At this time, it is assumed that the bottom surface is in an incompletely locked state, that is, the bottom surface is not yet in a locked state.

  FIG. 7 shows an operation sequence (4) in which the bottom raising guide 40b is turned and the bottom of the second side face 6 of the one-touch carton 2 is pushed in and completely locked.

  The bottom hoisting guide 40b pivots about the fulcrum 40d and pushes the left end of the bottom of the second side face 6 and pushes the bottom lock 3 to bring the unlocked or incomplete lock into a completely locked state.

  FIG. 8 shows a state in which the operation order (5) the upper raising guide 50b turns and pushes the upper part of the second side surface of the one-touch carton 2 so as to make the carton closer to a square shape.

  The upper hoisting guide 50b turns around the fulcrum 50d and pushes the upper left side to bring the carton closer to a square shape. In addition, the bottom face lock becomes more complete by setting the timing of pushing immediately after the bottom portion raising guide 40b hits the bottom portion.

  FIG. 9 shows the operation sequence (6) The bottom hoisting guide 40b and the upper hoisting guide 50b are returned, the suction of the hoisting vacuum pad is released, and the carton 2 whose hoisted bottom is completely locked is moved downstream. A state of dropping onto the conveyor 200 is shown.

  That is, if the CPU of the control unit 60 determines that the bottom hoisting guide 40b and the upper hoisting guide 50b are operated and pushed into the second side surface 6, the control signals are immediately sent to the air cylinders 40a and 50a. Then, the air cylinder is pulled back, the bottom hoisting guide 40b and the upper hoisting guide 50b are separated from the second side surface 6, and the suction of the hoisting vacuum pad 20c is released, and the carton 2 is moved downward. It is dropped on the downstream conveyor 200 in the area.

  The dropped carton 2 is conveyed to a conveyor for storing contents.
