Description

The present invention relates to a bag processing machine, a bag packaging machine, and a bag processing method.

2. Description of the Related Art Conventionally, spouted bags (pouches) have been widely used for enclosing fluid beverages, detergents, and the like in liquid or jelly form. The consumer can discharge the contents inside the bag out of the bag through the spout portion. A bag processing machine is used to perform a predetermined process on such a bag. For example, in order to fill a bag with beverage, detergent, etc., a filling device is used that fills the bag with beverage, detergent, etc. through a spout while transferring the bag along a predetermined path.

Patent Literature 1 discloses such a filling device. The filling device disclosed in Patent Literature 1 has a plurality of processing units along the straight line of movement of the spouted bag, and a transfer line for transferring the spouted bag on the straight line of movement. The spout-equipped bag is suspended and conveyed in a position in which the width direction of the bag is along the moving straight line. In particular, when the multiple hooks are viewed from above, the spouts held by the hooks of the multiple hooks are moved in a direction along the moving straight line and in a direction crossing the moving straight lines so as to draw a rectangular trajectory. The bag moves along the straight line of movement. As a result, the spout-equipped bag performs so-called intermittent movement, in which the operation of moving to the next process and stopping is repeated.

Next, the transfer device 30 will be described. 2 to 8B are diagrams for explaining the holding portion 40 of the transfer device 30. FIG. The transfer device 30 is a device that transfers the bag body 200 along a predetermined track. In particular, in the examples shown in FIGS. 1 to 10, the transfer device 30 transfers the bags 200 linearly along the transfer direction d1. The bag body 200 stops at a predetermined station while being processed, and is transferred to the next station and stops when the processing is completed. That is, the bag body 200 is intermittently transferred by the transfer device 30 .

The transfer device 30 includes a holding section 40 that holds the bag body 200 and a driving section 35 that drives the holding section 40 . In this embodiment, the holding part 40 holds the spout 210 of the bag body 200 . Among other things, the retainer 40 retains the ribs 212 of the spout 210 . In addition, in this embodiment, the entire transfer device 30 is driven by one drive unit 35 .

The holding part 40 has a first moving block 41 , a second moving block 42 , a first fixed block 51 and a second fixed block 52 . The first moving block 41, the second moving block 42, the first fixed block 51, and the second fixed block 52 are members linearly extending along the transfer direction d1. The first moving block 41 has a first portion 41a and a second portion 41b connected at an angle to each other. In this embodiment, the first portion 41a extends horizontally and the second portion 41b extends vertically. That is, the first moving block 41 has a horizontally extending first portion 41a and a vertically extending second portion 41b. Therefore, the first portion 41a and the second portion 41b are orthogonally connected to each other. The first portion 41a and the second portion 41b can be connected at any angle without being limited to this.

The first portion 41a of the first moving block 41 has a first holding claw 41c at its tip.

The first holding claws 41c have a function of transferring the bag body 200 between the plurality of processing sections S1 to S12. The first holding claws 41c hold the spout 210 attached to the bag body 200. As shown in FIG. In particular, in this embodiment, the first holding claw 41c has a first groove portion 41d capable of holding the rib 212 of the spout 210, and when the spout 210 enters the first groove portion 41d, the rib 212 is It is held by the first groove portion 41d. The first moving block 41 is configured to be movable in the transfer direction d1 and the lateral direction d2. Therefore, the first groove portion 41d of the first holding claw 41c is also movable in the transfer direction d1 and the horizontal direction d2. As will be described later, in the transfer device 30, the bag body 200 is transferred between the processing sections S1 to S12 by moving the first groove portion 41d in the transfer direction d1 and the lateral direction d2.

The width of the first groove 41d along the transfer direction d1 is set so that the spout 210 can enter the first groove 41d and the rib 212 is held by the first groove 41d. Therefore, the width of the first groove portion 41d along the transfer direction d1 is greater than the width of the body portion of the spout 210 when the bag body 200 is held with the spout 210 facing upward, and the rib 212 along the horizontal dimension. The shapes and dimensions of the plurality of first grooves 41d provided in the first moving block 41 are the same. Also, the interval between two adjacent first groove portions 41d is set according to the interval between the two processing devices provided in each of the processing units S1 to S12. The plurality of first grooves 41d may be arranged at equal intervals along the transfer direction d1.

The second moving block 42 has a first portion 42a and a second portion 42b connected at an angle to each other. In this embodiment, the first portion 42a extends horizontally and the second portion 42b extends vertically. That is, the second moving block 42 has a horizontally extending first portion 42a and a vertically extending second portion 42b. Therefore, the first portion 42a and the second portion 42b are orthogonally connected to each other. Not limited to this, the first portion 42a and the second portion 42b may be connected at any angle.

The first portion 42a of the second moving block 42 has a second holding claw 42c at its tip. Here, the tip of the first portion 42a refers to the end opposite to the portion connected to the second portion 42b in the horizontal direction d2. The second holding claws 42c have the function of fixing the bag body 200 while the bag body 200 is being processed in each of the processing sections S1 to S12. The second holding claw 42c holds the spout 210 attached to the bag body 200. As shown in FIG. In particular, in this embodiment, the second holding claw 42c has a second groove 42d capable of holding the rib 212 of the spout 210, and when the spout 210 enters the second groove 42d, the rib 212 is It is held by the second groove portion 42d. The second moving block 42 is configured to be movable in the horizontal direction d2. Therefore, the second groove portion 42d of the second holding claw 42c is also movable in the lateral direction d2. Note that, in the present embodiment, the second moving block 42 does not move in the transfer direction d1. Therefore, the second groove portion 42d of the second holding claw 42c also does not move in the transfer direction d1.

The width of the second groove 42d along the transport direction d1 is set so that the spout 210 can enter the second groove 42d and the rib 212 is held by the second groove 42d. Therefore, the width of the second groove portion 42d along the transfer direction d1 is greater than the width of the body portion of the spout 210 when the bag body 200 is held with the spout 210 facing upward, and 212 along the horizontal dimension. The shape and dimensions of the plurality of second grooves 42d provided in the second moving block 42 are the same. The shape and dimensions of the second groove 42 d may be the same as the shape and dimensions of the first groove 41 d of the first moving block 41 . Also, the interval between two adjacent second groove portions 42d is set according to the interval between the two processing devices provided in each of the processing sections S1 to S12. The plurality of second grooves 42d may be arranged at regular intervals along the transfer direction d1. The interval between two adjacent second groove portions 42 d is preferably the same as the interval between two adjacent first groove portions 41 d in the first moving block 41 .

As shown in FIG. 3A, when viewed along the vertical direction, the first holding claw 41c of the first moving block 41 and the second holding claw 42c of the second moving block 42 face each other. ing. In particular, the first holding claw 41c and the second holding claw 42c face each other along the lateral direction d2. In addition, the two most upstream first grooves 41d of the plurality of first grooves 41d of the first moving block 41 face the bag supply device 11 of the first station (bag supply unit) S1. (see FIG. 3A), the other first groove portion 41d of the plurality of first groove portions 41d is arranged at a position facing the second groove portion 42d along the lateral direction d2. This allows the bag body 200 to be transferred between the first groove portion 41d and the second groove portion 42d.

The first holding claw 41c of the first moving block 41 and the second holding claw 42c of the second moving block 42 may be arranged at different heights along the vertical direction d3. In the example shown in FIG. 5B, the second holding claw 42c is positioned below the first holding claw 41c. Accordingly, as the first moving block 41 and the second moving block 42 move in the horizontal direction d2, the first holding claw 41c and the second holding claw 42c can overlap along the vertical direction d3. In this case, the first holding claw 41c and the second holding claw 42c may hold ribs 212 different from each other. In the example shown in FIG. 5B, spout 210 has three ribs 212 arranged in the vertical direction (vertical direction d3). The first holding claw 41c can hold the uppermost rib 212, and the second holding claw 42c can hold the second rib 212 from the top. As a result, when the bag body 200 is delivered between the first holding claws 41c and the second holding claws 42c, the bag body 200 (the spout 210) is held by both the first holding claws 41c and the second holding claws 42c at a certain moment. ) can be retained. Therefore, the bag body 200 can be properly transferred between the first holding claws 41c and the second holding claws 42c.

The first fixed block 51 has a first portion 51a and a second portion 51b connected at an angle to each other. In this embodiment, the first portion 51a extends horizontally and the second portion 51b extends vertically. That is, the first fixed block 51 has a horizontally extending first portion 51a and a vertically extending second portion 51b. Therefore, the first portion 51a and the second portion 51b are orthogonally connected to each other. The first portion 51a and the second portion 51b are not limited to this, and may be connected at any angle.

The second fixed block 52 has a first portion 52a and a second portion 52b connected at an angle to each other. In this embodiment, the first portion 52a extends horizontally and the second portion 52b extends vertically. That is, the second fixed block 52 has a horizontally extending first portion 52a and a vertically extending second portion 52b. Therefore, the first portion 52a and the second portion 52b are orthogonally connected to each other. The first portion 52a and the second portion 52b are not limited to this, and may be connected at any angle.

The positions of both the first fixed block 51 and the second fixed block 52 are fixed. That is, the first fixed block 51 and the second fixed block 52 do not move in either the transfer direction d1 or the lateral direction d2. In this specification, "fixation" of the first fixed block 51 and the second fixed block 52 means that the positions of the first fixed block 51 and the second fixed block 52 are fixed. The first fixed block 51 is arranged below the first moving block 41 . More specifically, the first fixed block 51 is arranged below the first portion 41 a of the first moving block 41 . Also, the second fixed block 52 is arranged below the second moving block 42 . More specifically, the second fixed block 52 is arranged below the first portion 42 a of the second moving block 42 .

The tip of the first portion 51a of the first fixed block 51 and the tip of the first portion 52a of the second fixed block 52 face each other. In particular, the tip of the first portion 51a of the first fixed block 51 and the tip of the first portion 52a of the second fixed block 52 face each other along the lateral direction d2. The tips of the first portions 51a and 52a refer to the opposite ends of the portions connected to the second portions 51b and 52b in the horizontal direction d2. The distance in the lateral direction d2 between the tip of the first portion 51a of the first fixed block 51 and the tip of the first portion 52a of the second fixed block 52 is such that the spout 210 is the first tip of the first fixed block 51. It can enter between the tip of the portion 51 a and the tip of the first portion 52 a of the second fixed block 52 , and the rib 212 extends between the first portion 51 a of the first fixed block 51 and the second fixed block 52 . It is set to be retained by the first portion 52a (see FIG. 4B). Therefore, the distance in the lateral direction d2 between the tip of the first portion 51a of the first fixed block 51 and the tip of the first portion 52a of the second fixed block 52 is It is greater than the width of the body of the spout 210 and less than the horizontal dimension of the ribs 212 when held facing up.

The first portion 51a of the first fixed block 51 and the first portion 52a of the second fixed block 52 may be arranged at different heights along the vertical direction d3. In the example shown in FIG. 4B, the first portion 52a of the second fixed block 52 is located below the first portion 51a of the first fixed block 51. In the example shown in FIG. This prevents the second moving block 42 and the second fixed block 52 from interfering with each other. In this case, the first portion 51a of the first fixed block 51 and the first portion 52a of the second fixed block 52 may hold ribs 212 different from each other. When the spout 210 has three ribs 212 arranged in the vertical direction (vertical direction d3), the first portion 51a of the first fixing block 51 holds the second rib 212 from the top. Well, the first portion 52 a of the second fixed block 52 may hold the lowermost rib 212 .

When the second moving block 42 moves in the lateral direction d2 and approaches the first fixed block 51, the bag body 200 is sandwiched and held between the second moving block 42 and the first fixed block 51. . That is, the first fixed block 51 can hold the bag body 200 in cooperation with the second moving block 42 . In particular, in this embodiment, the bag body 200 is sandwiched and fixed between the second moving block 42 and the first fixed block 51 when approaching the first fixed block 51 . That is, the first fixing block 51 can cooperate with the second moving block 42 to fix the bag body 200 . Further, when the first moving block 41 moves in the horizontal direction d2 and approaches the second fixed block 52, the bag body 200 is held between the first moving block 41 and the second fixed block 52. be done. That is, the second fixed block 52 can hold the bag body 200 in cooperation with the first moving block 41 . In this embodiment, the bag body 200 is movable along the transfer direction d1 while being held by the first moving block 41 and the second fixed block 52 .

The operation of the holding portion 40 of the transfer device 30 will be described with reference to FIGS. 2 to 8B. In particular, operations of the first moving block 41 and the second moving block 42 of the holding portion 40 will be described. 2 to 8B, illustration of the main body of the bag body 200 is omitted, and only the spout 210 portion is illustrated.

The bag supply device 11 uses the vibration applied to the rails 12 to transfer the bags 200 to the ends of the rails 12 . The bag body 200 positioned at the tip of the rail 12 is transferred from the rail 12 to the transfer device 30 by the transfer member 13 .

FIG. 3A is a top view showing transfer device 30 as bags 200 are transferred from rail 12 to transfer device 30. FIG. FIG. 3B is an enlarged view of a part of FIG. 3A. FIG. 3C is a side view corresponding to FIG. 3A. In particular, FIG. 3C is a view of the transfer device 30 along the transfer direction d1.

The first moving block 41 is movable in the transfer direction d1 and the lateral direction d2. In this embodiment, the first moving block 41 moves downstream along the transport direction d1 from the position shown in FIG. move away (see FIG. 6A), move upstream along the transfer direction d1 (see FIG. 7), move toward the second moving block 42 along the lateral direction d2, and Return to the position shown in 3A. In this specification, when the first moving block 41 is located upstream along the transfer direction d1 and closer to the second moving block 42 (see FIG. 3A), the first moving block 41 is referred to as the "first position ”. Also, when the first moving block 41 is positioned downstream in the transfer direction d1 and closer to the second moving block 42 (see FIG. 4A), the first moving block 41 is at the "second position". shall be When the first moving block 41 is positioned downstream in the transfer direction d1 and away from the second moving block 42 (see FIG. 6A), the first moving block 41 is considered to be in the "third position". do. Furthermore, when the first moving block 41 is located upstream in the transfer direction d1 and away from the second moving block 42 (see FIG. 7), the first moving block 41 is at the "fourth position". shall be Thus, in FIG. 3A the first moving block 41 is in the first position, in FIG. 4A the first moving block 41 is in the second position, in FIG. 6A the first moving block 41 is in the third position, In FIG. 7, the first moving block 41 is in the fourth position.

Also, the second moving block 42 is movable in the lateral direction d2. In this embodiment, the second moving block 42 moves from the position shown in FIG. 3A along the lateral direction d2 toward the first moving block 41 (see FIG. 5A), to move away from the first moving block 41 and return to the position shown in FIG. 3A. In this specification, when the second moving block 42 is positioned away from the first moving block 41 (see FIG. 3A), the second moving block 42 is assumed to be in the "first position". Also, when the second moving block 42 is positioned closer to the first moving block 41 (see FIG. 5A), the second moving block 42 is assumed to be in the "second position". Thus, in Figures 3A and 4A the second moving block 42 is in the first position and in Figures 5A, 6A, 7 and 8A the second moving block 42 is in the second position.

As shown in FIGS. 3A and 3B, when the first moving block 41 is at the first position, the two most upstream first grooves 41d of the first moving block 41 are located at the first position. The first groove portion 41d is positioned to face the bag feeding device 11 of the first station (bag feeding portion) S1. The two first grooves 41d adjacent to the two most upstream first grooves 41d are the two most upstream second grooves 42d of the plurality of second grooves 42d of the second moving block 42. It is located at a position facing the groove portion 42d. When the spout 210 positioned at the tip of the rail 12 is moved toward the first moving block 41 by the transfer member 13, the spout 210 enters the corresponding first groove 41d. As shown in FIG. 3C, the first groove portion 41d enters between the uppermost rib 212 of the spout 210 and the second rib 212 from the top. hold. As a result, the holding claws 41c (first groove portion 41d) of the first moving block 41 hold the bag body 200 (spout 210).

When the first moving block 41 moves to the second position, as shown in FIG. 4A, the bag body 200 held in the first groove portion 41d of the first moving block 41 moves downstream along the transfer direction d1. and stop at the second station (printing section) S2. At this time, the spout 210 enters between the tip of the first portion 51 a of the first fixed block 51 and the tip of the first portion 52 a of the second fixed block 52 . The distance between the tip of the first portion 51 a of the first fixed block 51 and the tip of the first portion 52 a of the second fixed block 52 is slightly larger than the width of the body of the spout 210 . In the example shown in FIG. 4B, the first portion 51a of the first fixed block 51 holds the second rib 212 from the top, and the first portion 52a of the second fixed block 52 holds the bottommost rib 212. It holds ribs 212 that do. Also, at this time, the second moving block 42 is at the first position.

The second moving block 42 is then moved to the second position (see FIG. 5A). As a result, the second holding claw 42c of the second moving block 42 moves toward the first moving block 41, and the spout 210 is positioned within the second groove portion 42d of the second holding claw 42c. In the example shown in FIG. 5B, the second groove portion 42d enters between the rib 212 located second from the top and the rib 212 located at the bottom of the spout 210, and the rib 212 located second from the top. 212 is retained. At this time, the body of the spout 210 is sandwiched between the second groove 42d of the second moving block 42 and the tip of the first portion 51a of the first fixed block 51 to hold the spout 210. As shown in FIG. That is, the first fixed block 51 and the second movable block 42 cooperate to hold the bag body 200 . In particular, the main body of the spout 210 is sandwiched and fixed between the second groove 42d of the second moving block 42 and the tip of the first portion 51a of the first fixed block 51 . That is, the first fixed block 51 and the second movable block 42 work together to fix the bag body 200 . In the second station (printing section) S2, printing is performed on the bag 200 while the position of the bag 200 is fixed.

While processing is being performed in each processing section S2-S12, the first moving block 41 returns to the first station (bag supply section) S1 to receive the next bag 200 to be processed. . First, the first moving block 41 moves to the third position (see FIG. 6A). Therefore, as shown in FIG. 6B, the first holding claw 41c of the first moving block 41 moves away from the second moving block 42 along the lateral direction d2. As a result, the first groove portion 41d of the first holding claw 41c is separated from the spout 210 and no longer holds the bag body 200 (spout 210). At this time, the main body of the spout 210 is sandwiched between the second groove 42d of the second moving block 42 and the tip of the first portion 51a of the first fixed block 51 and remains fixed.

Next, the first moving block 41 moves to the fourth position (see FIG. 7). At this time, the two most upstream first grooves 41d of the plurality of first grooves 41d of the first moving block 41 are separated from the bag supply device 11 of the first station (bag supply unit) S1. and facing the bag supply device 11 . The two first grooves 41d adjacent to the two most upstream first grooves 41d are the two most upstream second grooves 42d of the plurality of second grooves 42d of the second moving block 42. It is located at a position facing the groove portion 42d.

Next, the first moving block 41 moves to the first position (see FIG. 8A). That is, the first holding claw 41c of the first moving block 41 moves toward the second moving block 42 along the lateral direction d2. As a result, of the plurality of first grooves 41d of the first moving block 41, the two most upstream first grooves 41d are brought closer to the bag supply device 11 of the first station (bag supply unit) S1. move to the desired position. Similarly, the two first groove portions 41d adjacent to the two most upstream first groove portions 41d are the two most upstream second groove portions 42d of the plurality of second groove portions 42d of the second moving block 42. It moves to a position close to the second groove portion 42d. At this time, as shown in FIG. 8B, the two first grooves 41d adjacent to the two furthest upstream first grooves 41d are two or more from the uppermost rib 212 of the spout 210. It enters between the second rib 212 and holds the uppermost rib 212 . At this time, the body portion of the spout 210 is positioned between the first groove portion 41d of the first moving block 41 and the tip of the first portion 52a of the second fixed block 52, and A fixed block 52 holds the spout 210 .

After that, the second moving block 42 moves away from the first moving block 41 along the lateral direction d2 and returns to the position shown in FIG. 3A. Therefore, the second holding claw 42c of the second moving block 42 moves away from the first moving block 41 along the lateral direction d2. As a result, of the plurality of second grooves 42d of the second moving block 42, the two most upstream second grooves 42d are separated from the spout 210 and do not hold the bag body 200 (spout 210). At this time, the body portion of the spout 210 is positioned and held between the first groove portion 41d of the first moving block 41 and the tip of the first portion 52a of the second fixed block 52 .

Transfer device 30 repeats the operations described above with reference to FIGS. 3A-8B. Of the plurality of first grooves 41d of the first moving block 41, two first grooves 41d adjacent to the two most upstream first grooves 41d hold the bags 200 (spouts 210). In this case, when the first moving block 41 moves from the first position to the second position, the bag body 200 also moves along the transfer direction d1 while being held by the first moving block 41, and is transferred to the next processing section. processing takes place. By repeating this, the bag body 200 is intermittently transferred along the transfer direction d1. While each spout 210 is fixed to the first fixed block 51 and the second moving block 42, the processing in each processing section is performed simultaneously.

An example of the operation of the bag processing machine 10 described above will be described with reference to FIGS. 9 to 11B. 9 is a diagram corresponding to FIG. 2, FIG. 10A is a diagram corresponding to FIG. 3B, and FIG. 10B is a diagram corresponding to FIG. 3C.

When supplying the bag 200 from the bag supply section S1 to the transfer device 30, the bag 200 is supplied while being held by the pair of rails 12 of the bag supply device 11, as shown in FIG. . The bag body 200 positioned at the tip of the rail 12 is transferred from the rail 12 to the transfer device 30 by the transfer member 13 . At this time, as shown in FIGS. 10A and 10B, the spout 210 is sufficiently positioned within the first groove portion 41d of the first moving block 41 compared to the example described with reference to FIGS. 3B and 3C. may be held in the first groove portion 41d without entering the groove. Also, as shown in FIGS. 10A and 10B, the spout 210 may be held in the first groove 41d of the moving block 41 in an inclined state.

When the first moving block 41 attempts to move from the first position to the second position, the spout 210 held in the first groove portion 41d of the first moving block 41 comes into contact with the first portion 52a of the second fixed block 52. (See FIGS. 11A and 11B). In this case, by pushing the first moving block 41 away from the second moving block 42, the distance between the first moving block 41 and the first fixed block 51 along the lateral direction d2 can change. . Also, a large vibration may occur in the first moving block 41 and the second fixed block 52 .

The contact of the spout 210 with the first portion 52a of the second fixed block 52 prevents the first moving block 41 from moving to the second position. If the transporting device 30 is continued to be driven by the driving section 35 in this state, a large load is applied to the driving section 35 and damage may occur to the driving section 35 . Therefore, in such a case, it is required to reduce the load that may occur on the drive unit 35 .

The bag processing machine 10 of this embodiment includes a measuring device 60 for measuring the vibration of the transfer device 30 or the distance between two members included in the transfer device 30 . Above all, in this embodiment, the bag processing machine 10 is equipped with one measuring device 60 . The measuring device 60 will be described below. FIG. 12 is a diagram showing an example of the measuring device 60. As shown in FIG.

The measuring device 60 measures the vibration of the transfer device 30 or the distance between two members included in the transfer device 30 (measurement step). A measurement result by the measuring device 60 , that is, a measured vibration or distance value is sent to the control device 70 . The control device 70 determines that the transfer device 30 is operating normally when the measurement result obtained by the measuring device 60 does not exceed a predetermined threshold value. On the other hand, when the measurement result by the measuring device 60 exceeds the predetermined threshold value, it is determined that an abnormality has occurred in the operation of the transfer device 30 . The control device 70 controls the transfer device 30 to stop transfer of the bag body 200 when the measurement result by the measurement device 60 exceeds a predetermined threshold value (transfer stop step). For example, the control device 70 stops the drive section 35 of the transfer device 30 . The control device 70 is not limited to this, and may control a clutch mechanism or the like to cut off power transmission from the drive section 35 to each part of the transfer device 30 . In this way, when the measurement result by the measuring device 60 exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the operation of the transfer device 30, and the transfer of the bag 200 is stopped. It is possible to effectively suppress damage to the drive unit 35 caused by the abnormality. Accordingly, it is possible to determine whether or not there is an abnormality in the transfer device 30 using one or a small number of measuring devices 60 . Therefore, the configuration of the bag processing machine 10 can be simplified. Also, an increase in the cost of the bag processing machine 10 can be suppressed.

Here, "when the measurement result by the measuring device exceeds a predetermined threshold" means when the measurement result by the measuring device is greater than the predetermined threshold, and when the measurement result by the measuring device is less than the predetermined threshold. includes both. That is, the control device 70 determines that the transfer device 30 is operating normally when the measurement result by the measuring device 60 is equal to or less than the predetermined threshold, and the control device 70 determines that the measurement result by the measuring device 60 is higher than the predetermined threshold. If it is large, it may be determined that an abnormality has occurred in the operation of the transfer device 30 . When the measurement result by the measuring device 60 is equal to or greater than a predetermined threshold, it is determined that the transfer device 30 is operating normally. It may be determined that an abnormality has occurred in the operation of the device 30 . Also, a first threshold and a second threshold larger than the first threshold are set, and the control device 70 controls the measurement result obtained by the measuring device 60 to be greater than or equal to the first threshold and less than or equal to the second threshold. If it is determined that the transfer device 30 is operating normally, and if the result of measurement by the measurement device 60 is smaller than the first threshold value or larger than the second threshold value, an abnormality has occurred in the operation of the transfer device 30. can be judged.

In the example shown in FIGS. 1 and 12 , the measuring device 60 has a distance measuring device 62 that measures the distance between two members included in the transfer device 30 . As shown in FIG. 1, the distance measuring device 62 is arranged on the upstream side of the holding section 40 in the transfer direction d1. The result of measurement by the distance measuring device 62 , that is, the value of the measured distance is sent to the control device 70 . If the distance value measured by the distance measuring device 62 does not exceed a predetermined threshold value, the control device 70 determines that the transfer device 30 is operating normally. On the other hand, when the value of the distance measured by the distance measuring device 62 exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the operation of the transfer device 30 .

In the illustrated example, the distance measuring device 62 measures the distance between part of the first moving block 41 and part of the first fixed block 51 . In particular, in the illustrated example, the distance measuring device 62 measures the distance between the second portion 41b of the first moving block 41 and the second portion 51b of the first fixed block 51. When the transfer device 30 is operating normally and the first moving block 41 is at the first position or the second position, the second portion 41b of the first moving block 41 and the second portion 51b of the first fixed block 51 is within a first range. On the other hand, when the distance between the second portion 41b of the first moving block 41 and the second portion 51b of the first fixed block 51 exceeds a predetermined threshold, that is, when the distance is outside the first range, Then, the control device 70 determines that an abnormality has occurred in the transfer device 30 . Further, when the transfer device 30 is operating normally and the first moving block 41 is at the third position or the fourth position, the second portion 41b of the first moving block 41 and the second portion 41b of the first fixed block 51 The distance between portion 51b is within a second range different from the first range. On the other hand, if the distance between the second portion 41b of the first moving block 41 and the second portion 51b of the first fixed block 51 exceeds the predetermined threshold, that is, if it is out of the second range, Then, the control device 70 determines that an abnormality has occurred in the transfer device 30 . Note that the distance measured by the distance measuring device 62 is not limited to the distance between the second portion 41 b of the first moving block 41 and the second portion 51 b of the first fixed block 51 . The distance measured by the distance measuring device 62 may be the distance between the second portion 42b of the second moving block 42 and the second portion 52b of the second fixed block 52, or may be included in the transfer device 30. It may be the distance between two other members.

FIG. 13 is a diagram showing another example of the measuring device 60. As shown in FIG. In the example shown in FIG. 13 , the measuring device 60 has a vibration measuring device 64 that measures vibrations of the transfer device 30 . The vibration measuring instrument 64 measures values related to vibration such as amplitude and waveform of any member of the transfer device 30 . A measurement result by the vibration measuring device 64 , that is, a value related to the measured vibration is sent to the control device 70 . The control device 70 determines that the transfer device 30 is operating normally when the vibration value measured by the vibration measuring device 64 does not exceed a predetermined threshold value. On the other hand, when the vibration-related value measured by the vibration measuring device 64 exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the operation of the transfer device 30 .

In the illustrated example, the vibration measuring device 64 is attached to the first portion 41 a of the first moving block 41 and measures values related to vibration of the first moving block 41 . When the transfer device 30 is operating normally, the value for the vibration of the first moving block 41 is within a predetermined range. On the other hand, when the vibration value of the first moving block 41 exceeds the predetermined threshold, that is, when it is out of the predetermined range, the control device 70 determines that the transfer device 30 has become abnormal. Note that the vibration-related value measured by the vibration measuring device 64 is not limited to the vibration-related value of the first moving block 41 . Note that the vibration measuring instrument 64 may be attached to the second portion 41b of the first moving block 41, or may be attached to other members such as the second moving block 42, the first fixed block 51, and the second fixed block 52. may be

The vibration measuring instrument 64 may be attached to the drive section 35 and measure values related to vibration of the drive section 35 . When a load is applied to the drive section 35 due to an operational abnormality that has occurred in the transfer device 30, the drive section 35 may vibrate abnormally. When the vibration measuring device 64 is attached to the drive unit 35, abnormal vibration generated in the drive unit 35 is detected, and according to the detection result, the transfer device 30 is caused to stop the transfer of the bag body 200. can be controlled. Specifically, the control device 70 determines that the transfer device 30 is operating normally when the vibration value of the drive unit 35 does not exceed a predetermined threshold value. On the other hand, when the vibration value of the drive unit 35 exceeds the predetermined threshold value, the control device 70 determines that an abnormality has occurred in the transfer device 30 and stops transfer of the bag 200 .

Accordingly, it is possible to determine whether or not there is an abnormality in the transfer device 30 using one or a small number of measuring devices 60 . Therefore, the configuration of the bag processing machine 10 can be simplified. Also, an increase in the cost of the bag processing machine 10 can be suppressed.

On the other hand, when the vibration value of the transfer table 32 exceeds a predetermined threshold value, that is, when it is out of a predetermined range, the control device 70 determines that the transfer device 30 has become abnormal. Note that the vibration-related value measured by the vibration measuring instrument 64 is not limited to the vibration-related value of the transfer table 32 .

In such a bag processing machine 10 as well, when the result of measurement by the measuring device 60 exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the operation of the transfer device 30, and the transfer of the bag 200 is stopped. As a result, it is possible to effectively prevent damage to the drive unit 35 caused by an abnormality occurring in the transfer device 30 . Accordingly, it is possible to determine whether or not there is an abnormality in the transfer device 30 using one or a small number of measuring devices 60 . Therefore, the configuration of the bag processing machine 10 can be simplified. Also, an increase in the cost of the bag processing machine 10 can be suppressed.
