Description

The present invention relates to a bag-shaped container supply device including a bag-shaped container stacking device for stacking and holding bag-shaped containers and a bag-shaped container transfer device for transferring the stacked bag-shaped containers at the top surface position.

As a conventional bag-shaped container (standing pouch) supply device, a packaging bag feeding device (see Patent Document 1) is known. Since the pouches are stocked on the conveyor along the longitudinal direction in this packaging bag feeding device, a space for the conveyor is required because the pouches are cut out one by one on the conveyor. Therefore, it is necessary to secure a space for arranging the conveyor.

Further, as a supply device and method for stacking standing pouches in the height direction, a bag removal device for an automatic packaging machine (see Patent Document 2) and an empty bag removal supply method from a bag storage device for an automatic packaging machine (Patent). Reference 3), a bag lifting device (see Patent Document 4), and a bag supply device provided with an elevating bag magazine device for an automatic packaging machine (see Patent Document 5).

The bag taking-out device of the automatic packaging machine is a device in which standing pouches are stacked in a bag storage device and the uppermost bag is taken out by a suction cup. This device does not consider the thickness of the bottom of the standing pouch, and the bag storage device is horizontal or tilted so that the bottom side of the standing pouch is in a high position. The standing pouches become fan-shaped when stacked, and the more stacked, the greater the inclination between the bottom and the opening, so this device cannot secure a large amount of stacking. In addition, 1) maintenance is not possible from the side of the bed because the stack device is under the bed; 2) maintenance from the side of the bed due to the problem of "1)" above when modifying a conventional machine. It cannot be done because it is not designed to do; 3) Raising the stacking device raises the level of the entire machine, resulting in poor workability.

The device used in the method of taking out and supplying empty bags from the bag storage device to the automatic packaging machine alternately changes the orientation of the opening and the bottom in order to correspond to bags having different thicknesses of the opening and the bottom such as a standing pouch. By stacking the bags while stacking them, the top-ranked bags are flattened, a sensor is provided above the storage bag to identify the opening / bottom of the bag, and the opening of the bag sucked by the sucker is in a specific direction based on the identification signal of the sensor. It is rotated so that it becomes. When loading the bags, this device is performed while manually changing the orientation of the opening and the bottom, which is troublesome and may cause a stacking error. Further, the means for identifying the pattern of the bag by the sensor and rotating the sucked bag complicates the structure and control of the device. Further, similarly to the bag taking-out device of the automatic wrapping machine, there is a problem that maintenance cannot be performed from the side surface of the bed because the drive device of the stack is lowered.

The bag lifting device is a device in which a large number of bags with thickened ends are stacked one above the other and sent out to the next process by the suction plate sequentially from the top surface, and is provided with a contact detection surface in the same plane as the suction surface of the suction plate. As a result, the suction plate is tilted according to the inclination of the bag. Since this device tilts the suction plate according to the inclination of the bag, the number of parts of the suction plate is large, the structure is complicated, and adjustment becomes difficult. Further, this device requires a large-scale stack device to be installed next to the machine, and there is a problem that it cannot be installed in a place where there is no work space when remodeling.

The bag supply device provided with the elevating bag magazine device for the automatic packaging machine is used in the elevating bag magazine device to solve the problem that the inclination between the bag mouth and the bottom becomes large when a large number of self-supporting bags are stacked. By providing a tilting device that tilts the bag receiving plate according to the vertical movement of the provided bag receiving plate, the bag located at the highest position is horizontal to the suction device. Since this device requires a guide device that guides the magazine and the receiving plate in the vertical direction, a driving device that moves the receiving plate up and down, and a tilting device that tilts according to the vertical movement of the receiving plate, the structure has a large number of parts. It becomes complicated and difficult to adjust. Further, since the object to be controlled is large, a large driving force and a large driving device in terms of space are required. Similar to other conventional techniques, there are problems that maintenance cannot be performed on the side where the device is installed and that the current work space is restricted.

Japanese Unexamined Patent Publication No. 5-51016 Japanese Patent No. 3084539 Japanese Patent No. 2583206 Japanese Unexamined Patent Publication No. 2014-8995 JP-A-2002-53108

An object of the present invention is that a bag-shaped container (hereinafter, also referred to as a "standing pouch") can be stably supplied to a filling machine and a packaging machine, a large number of standing pouches can be stocked, and a compact bag-shaped container can be stocked. The purpose is to provide a container supply device.

In order to solve the above problems, the present inventor first provides a bag-shaped container stacking device for stacking and holding bag-shaped containers and a bag-shaped container transferring device for transferring the stacked bag-shaped containers at the top surface position. It was configured as a bag-shaped container supply device provided. That is, 1) The bag-shaped container stacking device stacks a bag-shaped container guide that regulates the bag-shaped container, a support lever that supports the lower surface side of the bag-shaped container in a flat state, and a driving means for the support lever. It is equipped with a sensor that detects the bag-shaped container at the top position; 2) The bag-shaped container guide extends diagonally in the vertical direction and tilts in the direction of delivery to the bag-shaped container transport device that transports the bag-shaped container. 3) When the bag-shaped container guide and the support lever are in the vertical state, the width of the mounting surface of the bag-shaped container on the support lever in the bag-shaped container guide in the front-rear direction becomes equal to the height of the bag-shaped container. 4) The support lever operates in an arc shape with the fulcrum on the side of the bag-shaped container transport device; 5) When the stacked top-level bag-shaped containers are picked up by the bag-shaped container transfer device, the support lever is based on the sensor information. To keep the level of the top surface of the stacked bag-shaped containers constant; As a result, the following effects were obtained.

Since the bag-shaped container guide is erected at an angle toward the bag-shaped container transport device, the bag-shaped containers in the space above the bag-shaped container guide are always aligned in the bag-shaped container transport device side direction of the bag-shaped container guide. The suction plate can always suck a certain part of the bag-shaped container. Further, the bag-shaped container guide and the support lever prevent the bag-shaped container from being caught.

When the bag-shaped containers are stacked on the bag-shaped container stacking device, the bag-shaped containers come into contact with the four sides of the bag-shaped container guide only when the front end of the support lever rises and reaches the uppermost position. 1) When the width in the front-rear direction orthogonal to the bag-shaped container guide is equal to the height of the bag-shaped container, it means that the bag-shaped container guide and the support lever are in the orthogonal (vertical) state. 2) The bag-shaped container guide When the width in the front-rear direction orthogonal to is smaller than the height of the bag-shaped container, it is the state before the bag-shaped container guide and the support lever are in the orthogonal (vertical) state, and in both cases 1) and 2) above, the highest position. Until, the stacked bag-shaped containers are in contact with two places (left and right sideways of the bag-shaped container) or three places (left and right side and bottom of the bag-shaped container) of the bag-shaped container guide. When the bottom is raised by the support lever, the resistance applied to the bag-shaped container is minimized. Even if the bag-shaped container guide and the support lever are in the uppermost position before they are in the orthogonal (vertical) state, the bag-shaped container in the space above the bag-shaped container guide when the bag-shaped container guide is in the uppermost position It is preferable that the bag-shaped container guides are always aligned in the bag-shaped container transport device side direction.

The arc-type mechanism of the present invention is simpler and more stable than the elevating bag magazine device described in Patent Document 5, and the bag-shaped container can be raised by the support lever. When raising the bottom with the elevating bag magazine device, the resistance applied to the bag-shaped container changes from the straight state to the slanted state to the straight state with the cam, but in the arc state, it is always constant. Becomes a resistance. Further, at the position where the bag-shaped container guide and the support lever are in the vertical state, the width of the bag-shaped container mounting surface on the support lever in the bag-shaped container guide in the front-rear direction is equal to the height of the bag-shaped container. The bag-shaped container is positioned by the bag-shaped container guide.

By using a cylinder device (robo cylinder), it is possible to perform fine drive with a small force (compared to the conventional technology), and stable movement can be realized.

When the support lever is in the lowest position (initial position), since the support lever is tilted downward, a large space can be secured in the bag-shaped container guide, so that the number of loaded bag-shaped containers can be secured. In the elevating bag magazine device described in Patent Document 5, the guide (bag receiving plate) is initially straight, but in the present invention, the number of loaded sheets is increased by tilting the support lever of the bag-shaped container magazine device from the beginning. In addition to being able to secure a large number of items, the arc-type mechanism of the present invention is more compact than the elevating bag magazine device described in Patent Document 5. As a result, all the devices can be mounted on the packaging filling machine bed. Moreover, it does not require a large drive. Further, since the support lever fulcrum of the bag-shaped container stacking device is located on the bag-shaped container transporting device side, the drive unit can be installed in the packaging filling machine, and the size becomes further compact.

One cycle from picking up the bag-shaped container with the suction plate to picking up the next bag-shaped container is 2 seconds. Since this device is compact, it is possible to perform the process from switching the bag-shaped container stacking device to adsorbing the next bag-shaped container in one cycle time.

Next, by providing a spring that urges the support lever in a direction that constantly lifts the support lever, the support lever loaded with the bag-shaped container can be raised with a smaller driving force. The force required to increase the weight of only the bag-shaped container (up to 400 sheets, 3 kg) and the force of the sliding resistance of the bag-shaped container and the bag-shaped container guide when lifting can be supplemented by the spring.

Further, the swing width (from the initial position to the uppermost position) angle of the support lever is preferably about 30 ° to 50 °. If this angle is too large, the bag-shaped container will stand too high and get caught in the support lever and the bag-shaped container guide. If it is too small, the load capacity of the bag-shaped container will be small.

Further, an air blowing means is provided above the bag-shaped container guide. When the uppermost bag-shaped containers stacked on the suction plate are picked up, the next bag-shaped containers may adhere together and deviate from the positioning position. At that time, if the next displaced bag container is adsorbed, adsorption failure occurs. Therefore, the bag container is returned to the positioning position by blowing air to prevent the adsorption failure.

That is, the present invention is as follows.

In the bag-shaped container supply unit (3) in FIG. 1, a bag-shaped container supply device (29) that delivers the bag-shaped container (C) to the bag-shaped container transport device (27) is installed to supply the bag-shaped container. The device (29) is composed of a bag-shaped container stacking device (8) and a bag-shaped container transfer device (25). The bag-shaped container stacking device (8) includes a bag-shaped container guide (11) that regulates the bag-shaped container (C) and a support lever (16) that supports the bag-shaped container (C) on the lower surface side in a flat state. ), An elevating cylinder device (20) that is a driving means of the support lever (16), and a first photoelectric sensor (13) that detects the stacked bag-shaped containers (C) on the uppermost surface. In FIG. 2, the first photoelectric sensor (13) senses in the left-right direction. The bag-shaped container stacking device (8) can be loaded with a maximum of 400 sheets, a total of 3 kg of the bag-shaped container (C).

As the elevating cylinder device (20), a Robo cylinder (manufactured by IAI) is preferable. The Robo cylinder is a cylinder device equipped with a stepping motor, which enables stable control and is not affected by the amount of supplied air unlike an air cylinder, so that the movement is stable without variation. Further, since the stepping motor is driven, the bag-shaped container (C) disappears, the support lever (16) rises while the first photoelectric sensor (13) is in the light input state, and the first photoelectric sensor (C) is moved by the next bag-shaped container (C). It is possible to respond to movements with different ascending strokes each time, such as 13) stopping ascending in a light-shielded state, and it is also possible to respond to the very small movement of one bag-shaped container (C), as well as speed and acceleration. Can be set, so fine control is possible.

The bag-shaped container guide (11) extends straight in the diagonally vertical direction, is inclined in the direction of passing to the bag-shaped container transport device (27) that transports the bag-shaped container (C), and is inclined on both left and right sides of the bag-shaped container (C). And the left and right bottoms can be regulated, and the support lever (16) only needs to have a back space that can operate in an arc shape. For example, the bag-shaped container (C) faces each other with a width dimension. A pair of left and right plate-shaped side guide members (11a, 11a) and two vertically long side guide members (11a, 11a) extending inward at right angles from the front long sides and provided at predetermined intervals. A plate-shaped front guide member (11b, 11b) and a pair of side guide members (11a, 11a) are provided between the rear long sides so as to face the front guide member (11b, 11b), and a support lever (16).

The width is the minimum value "B" (see FIG. 3). The size of "B" is equal to the height of the bag-shaped container (C), and the bag-shaped container (C) is positioned by the bag-shaped container guide (11). Further, the width in the front-rear direction of the mounting surface of the bag-shaped container (C) on the support lever (16) in the bag-shaped container guide (11) when the support lever (16) is in the lowest position is the maximum value. It becomes "A". The size of "A" is about 1.3 times the size of "B".

The position where the suction plate (26) sucks the bag-shaped container (C) is based on the back guide member (11d) of the bag-shaped container guide (11), and is 30 mm in the vertical direction from the back guide member (11d). Adsorption is performed at a degree, that is, at a position above the bag-shaped container (C).

4 and 5 are a plan view and a front view of the bag-shaped container supply device (29) in FIG. 1, respectively. The bag-shaped container stacking device (8) is composed of two rows on the left and right on the plate (21). Since the left and right columns have the same structure, only the right column is marked. When the plate (21) is in the solid line position, the bag-shaped container transfer device (25), the second photoelectric sensor (14), and the air injection nozzle (24) are installed in the right column so as to correspond to each other. The bag-shaped container (C) is delivered from the row to the bag-shaped container transport device (27). A slider (22) is installed on the lower surface of the plate (21), a rail (23) is installed on the upper surface of the packaging filling machine bed (2), and the slider (22) is slidable on the rail (23). A bracket (32) is fixed to a first stand (31) erected on the packaging filling machine bed (2). The right end of the slide cylinder device (34) is swingably attached to the cylinder device fixing portion (33) located above the bracket (32) so as to be able to follow the movement of the slide lever (38). There is. The tip of the first slide rod (35) that moves forward and backward by the slide cylinder device (34) is attached to the central portion of the slide lever (38). The upper part of the slide lever (38) is attached to the slide lever fulcrum (37) located on the upper part of the second stand (36) erected on the packaging filling machine bed (2), and the lower tip portion is the second slide. It is attached to the left tip of the rod (39). The slide lever (38) swings around the slide lever fulcrum (37). The right end portion of the second slide rod (39) is swingably attached to the joint portion (40) attached to the front portion of the left end of the plate (21).

Explaining the delivery operation from the bag-shaped container supply device (29) to the bag-shaped container transport device (27), first, the bag-shaped container (C) on the uppermost surface stacked on the support lever (16) is attached to the suction plate (26). ), The bag-shaped container transfer device (25) moves from the solid line to the two-point chain line by a driving means (not shown) and delivers it to the bag-shaped container transport device (27). At this time, from the moment when the bag-shaped container (C) is sucked by the suction plate (26) to the position where the sucked bag-shaped container (C) is not affected by air, the air injection nozzle is set according to the timing. Air is not injected from (24).

Then, when the bag-shaped container (C) on the uppermost surface is taken out and the first photoelectric sensor (13) is in the light input state, the elevating cylinder device (20) is driven by the next bag-shaped container (C). The elevating rod (19) operates in the forward direction until the first photoelectric sensor (13) is shielded from light. Then, by moving the lifting lever (18) from the dotted line toward the solid line (see FIG. 2), the support lever (16) is centered on the support lever fulcrum (17), and the first photoelectric sensor (13) is moved. It rises in an arc until it is shielded from light by the next bag-shaped container (C). The bag-shaped container (C) is continuously delivered from the bag-shaped container supply device (29) to the bag-shaped container transport device (27), and when the support lever (16) reaches the highest position, the support lever (16) stops. .. At this time, the number of bag-shaped containers (C) on the support lever (16) is about 50, and the bags are continuously delivered to the bag-shaped container transport device (27) until these are exhausted.

Since the support lever (16) repeatedly rises and stops due to the light entering and blocking of the first photoelectric sensor (13), the rising stroke is not constant. Further, when the first photoelectric sensor (13) continues to be shielded from light by the next bag-shaped container (C) even if the stacked bag-shaped containers (C) on the uppermost surface are taken out by the suction plate (26). The support lever (16) does not rise (see FIGS. 2 and 3).
