Description

  The present invention relates to a container repair device and a container repair method for repairing deformation of a container having a cylindrical cylindrical portion such as a skirt portion of a beer barrel filled with beverages such as beer and sparkling liquor.

  As is well known, a container for distributing a beverage manufactured in a manufacturing factory such as a beer barrel to a restaurant or the like is repeatedly used a plurality of times. Such a container is made of a metal such as stainless steel, and a part of the container may be deformed when it is struck during loading and unloading. Therefore, a repair device is known in which a repair tool is inserted into the beer barrel and the deformed portion of the upper mirror and the lower mirror is pressed from the inside with the repair tool to restore the deformation of the beer barrel (Patent Document 1). reference).

Japanese Patent No. 3572331

  By the way, containers, such as a beer barrel, are provided with the cylindrical skirt part in order to pile up a container stably or to make it easy to hold. Generally, this skirt portion is also formed of a metal such as stainless steel. Therefore, it may be deformed depending on the handling during distribution. When the skirt part is deformed, there arises a problem that the container easily falls over or cannot be stacked. Therefore, repair is performed by hitting the deformed portion of the skirt portion with a hammer or the like to restore the original shape, but such manual work places a heavy burden on the operator. The device of Patent Document 1 repairs deformation of an upper mirror and a lower mirror of a portion filled with beer, and does not disclose a device that repairs deformation of a cylindrical cylindrical portion such as a skirt portion.

  Accordingly, the present invention provides a container repair device and a container repair method that can repair deformation of a cylindrical cylindrical portion such as a skirt portion provided in a container more easily than before and can reduce the burden on an operator. The purpose is to provide.

  A first container repair device of the present invention is a container (100) having a main body (101) filled with contents and a cylindrical skirt (102, 103) extending in the vertical direction from the main body. In the container repairing device (1) for repairing the deformation of the skirt portion, the first has a concave portion (31a) which is recessed so that the cross section becomes a concave curve with the central portion at the bottom and is formed in a curved surface extending in one direction. The pressing member (31) has a convex portion (33a) whose cross section is a convex curve with the central portion at the tip and is formed in a curved surface extending in one direction, and the convex portion extends in the same direction as the concave portion. And the second pressing member (33) provided so as to oppose and the inner peripheral side of the deformed portion (102d) deformed in the skirt portion, and the convex portion is disposed on the outer peripheral side of the deformed portion And the recess is disposed in Restraining means (20) for restraining the container so that the container is fixed in a state where the downward direction is aligned with the extending direction of the convex part and the concave part, and repairing by sandwiching the deformed part between the concave part and the convex part At least one of the first press member and the second press member so that a positional relationship between the first press member and the second press member changes between a position (P4) and a release position (P3) for releasing the pinching. Actuator means (34) for driving any one of them, and at least the central portion of the concave portion is more deformed than the state before deformation when the deformed portion is sandwiched between the concave portion and the convex portion. It is formed with a curved surface having a diameter (R1) smaller than the diameter of the outer periphery (Rout) of the skirt portion so as to bulge toward the outer peripheral side, and the convex portion has a diameter equal to or smaller than the diameter of the curved surface forming the central portion of the concave portion ( By being formed with a curved surface of 2), to solve the problems described above.

  According to the first container repairing apparatus of the present invention, the container is fixed by the restraining means, and then the positional relationship between the first press member and the second press member is changed to the repair position by the actuator means. The deformable member can be sandwiched between the press member and the second press member. Since the central portion of the concave portion of the first press member is formed with a curved surface having a diameter smaller than the diameter of the outer periphery of the skirt portion, the deformed portion is in a state before being deformed when the deformed portion is sandwiched between the convex portion and the concave portion. Can be inflated outside. In other words, when the deformed portion is sandwiched between the convex portion and the concave portion, the deformed portion can be warped outward from the state before the deformation. In general, when repairing a deformed metal such as stainless steel, a phenomenon that the deformed part after repair slightly returns to the shape at the time of deformation, a so-called return occurs. As described above, in the first container repair device of the present invention, when the deformed portion is sandwiched between the convex portion and the concave portion, the deformed portion is expanded outward from the shape before the deformation. For example, the deformed portion is bent inward and deformed. When the skirt portion is sandwiched between the convex portion and the concave portion, the skirt portion can be further deformed outward from the shape before the deformation. That is, the repair which considered the return after repair of a deformation | transformation part by a convex part and a recessed part can be performed. Therefore, the deformed portion can be returned to the substantially same shape as the shape before the deformation by returning the deformed portion when the pinching is released by the convex portion and the concave portion. Therefore, the deformation of the skirt portion can be repaired more easily than before. In addition, since the work of hitting the deformed portion with a hammer or the like is not necessary, the burden on the operator can be reduced.

  In one form of the first container repairing apparatus of the present invention, the first press member includes a first jig part (36) provided with the recess and a first fixing part to which the first jig part is fixed. (35), and the first jig part may be detachable from the first fixing part. When repairing various containers having different skirt diameters, it is necessary to replace the recesses in accordance with the diameter of the skirt of the container to be repaired. In this case, since the first jig portion provided with the recess is detachable from the first fixed portion, various containers having different skirt diameters are repaired by replacing only the first jig portion. can do. Therefore, it is possible to simplify the work required to make the container repair device correspond to various containers having different skirt diameters, and shorten the work time.

  In one form of the first container repairing apparatus of the present invention, the second press member includes a second jig part (39) provided with the convex part and a second fixing to which the second jig part is fixed. Part (38), and the second jig part may be detachable from the second fixing part. Also in this case, since the second jig portion provided with the convex portion can be attached to and detached from the second fixed portion, various containers having different skirt diameters can be repaired only by replacing the second jig portion. Can do. Therefore, it is possible to simplify the work required to make the container repair device correspond to various containers having different skirt diameters, and shorten the work time.

  The second container repair device of the present invention is a container (100) having a main body (101) filled with contents and a cylindrical skirt (102, 103) extending in the vertical direction from the main body. In the container repairing device (1) for repairing the deformation of the skirt portion, the container has a concave portion (31a) which is recessed so that the cross section becomes a concave curve with the central portion at the bottom, and is formed in a curved surface extending in one direction, A first press member (31) fixed so that the curved surface of the concave portion is recessed downward, and a convex portion (33a) formed by a curved surface whose cross section is a convex curve with the central portion at the tip and extending in one direction And the convex portion extends in the same direction as the concave portion, and is provided above the first press member so that the convex portion and the concave portion face each other, and is vertically guided by the guide means (32). 2nd press part supported so that movement is possible (33) and the concave portion of the first press member is disposed on the outer peripheral side of the deformed portion (102d) of the skirt portion, and the second press member is disposed on the inner peripheral side of the deformed portion. A restraining means (20) for restraining the main body portion of the container so that the container is fixed in a state where the convex portion is disposed and the vertical direction is aligned with the extending direction of the convex portion and the concave portion. And a repair position (P4) for sandwiching the deformed portion between the concave portion of the first press member and the convex portion of the second press member to return the deformed portion to the shape before deformation, and the second press member Actuator means (34) for driving the second press member between a release position (P3) separated from the deformed portion, and at least a central portion of the concave portion is formed by the concave portion and the convex portion. Deformation part The deformed portion is formed with a curved surface having a diameter (R1) smaller than the outer peripheral diameter (Rout) of the skirt portion so that the deformed portion swells to the outer peripheral side than the state before the deformation when sandwiched, and the convex portion is the concave portion The above-described problems are solved by being formed with a curved surface having a diameter (R2) that is equal to or smaller than the diameter of the curved surface forming the central portion of the first.

  According to the second container repair device of the present invention, the container is restrained by the restraining means, and then the second press member is driven downward by the actuator means, whereby the concave portion of the first press member and the convexity of the second press member are driven. The deformed part can be sandwiched between the parts. Similarly to the first container repair device of the present invention, the second container repair device of the present invention is formed with a curved surface having a diameter smaller than the diameter of the outer periphery of the skirt portion at the center of the concave portion of the first press member. When the deformed part is sandwiched between the convex part and the concave part, the deformed part can be expanded outward from the state before the deformation, and the convex part and the concave part are repaired in consideration of the return after the repair of the deformed part. be able to. Therefore, the deformed portion can be returned to the substantially same shape as the shape before the deformation by returning the deformed portion when the pinching is released by the convex portion and the concave portion. As described above, according to the second container repair device of the present invention, after the container is restrained by the restraining means, the deformation of the skirt portion can be repaired only by operating the actuator means. Therefore, the deformation of the skirt portion can be repaired more easily than before. In addition, since the work of hitting the deformed portion with a hammer or the like is not necessary, the burden on the operator can be reduced.

  In one form of the second container repairing apparatus of the present invention, the restraining means includes a main body support portion (21) for supporting a main body portion of the container having the deformed portion placed in a state of being laid down from below, A container provided above the main body support portion and movable between a restraining position (P1) for pressing the main body portion of the container supported by the main body support portion and a restraint releasing position (P2) for releasing the press. A pressing member (23) and pressing member driving actuator means (24) for driving the container pressing member between the constraint position and the constraint release position may be provided. In this case, after the container is placed on the main body support portion, the container can be restrained by operating the pressing member driving actuator means to drive the container pressing member to the restraining position.

  In one form of the second container repairing apparatus of the present invention, the skirt portion includes a cylindrical trunk portion (102a) and a member that is provided at one end of the trunk portion and forms the trunk portion. A curled portion (102b) rounded inward, and the second press member includes a pocket portion (39b) in which the curled portion is accommodated when the second press member is driven to the repair position. ) May be provided. In this case, even if the second press member is driven to the repair position and the body portion of the skirt portion is sandwiched between the first press member and the second press member, the curl portion is accommodated in the pocket portion of the second press member. The curled portion can be prevented from being crushed by the press member.

  In one form of the second container repairing apparatus of the present invention, the first press member includes a first jig part (36) provided with the recess and a first fixing part to which the first jig part is fixed. (35), and the first jig part may be detachable from the first fixing part. The second press member includes a second jig part (39) provided with the convex part, and a second fixing part (38) to which the second jig part is fixed. The jig part may be detachable from the second fixing part. When repairing various containers having different skirt diameters, it is necessary to replace the concave and convex portions according to the diameter of the skirt of the container to be repaired. In these forms, since the first jig part provided with the concave part or the second jig part provided with the convex part can be attached and detached, the skirt part can be replaced only by replacing the first jig part or the second jig part. Various containers with different diameters can be repaired. Therefore, it is possible to simplify the work required to make the container repair device correspond to various containers having different skirt diameters, and to shorten the work time.

  The container repairing method of the present invention is the container repairing method for repairing deformation of the skirt portion of the container using the second container repairing device described above, when the second press member is moved downward. A position fixing step (S1) for fixing the position of the container to be repaired by the restraining means so that the convex portion of the second press member is in contact with a predetermined position closer to the main body than the tip of the deformed portion; A repairing step of moving the second press member to the repairing position by operating the actuator means so that the predetermined position of the deformed portion of the container whose position is fixed in the process is sandwiched between the convex part and the concave part (S2) is provided to solve the above-described problem.

  According to the container repair method of the present invention, the position of the container is fixed by the restraining means so that the convex portion of the second press member hits the predetermined position of the deformed portion, and then the second press member is moved to the repair position. The deformed portion is sandwiched between the concave portion of the first press member and the convex portion of the second press member, so that the deformed portion can be returned to a shape substantially the same as the shape before the deformation. Therefore, similarly to the second container repairing apparatus of the present invention, the deformation of the skirt portion can be repaired more easily than before. In addition, the burden on the operator can be reduced.

  In one form of the container repair method of the present invention, in the repair step, first, a target position that is set between the release position and the repair position and is gradually changed toward the repair position, and the release position, The second press member may be reciprocated a plurality of times in between, and then the actuator means may be operated so that the second press member moves to the repair position. In this way, by changing the target position gradually toward the repair position and moving the second press member a plurality of times between the target position and the release position, a large force is applied to the deformed portion at once. Can be prevented. Therefore, an excessive force is applied to the deformed portion, and this can prevent the skirt portion from being damaged.

  In one form of the container repair method of the present invention, when the second press member is moved downward, the restraint means repairs the target so that the convex portion of the second press member hits the tip of the deformed portion. The position of the container is fixed, and then the actuator means is operated so that the distal end of the deformed portion is pushed downward until the outer periphery of the deformed portion of the container whose position is fixed by the restraining means contacts the first press member. A pre-repair step (S3) for moving the second press member downward may be performed before the position fixing step. In this case, for example, even if the skirt portion is bent inward to such an extent that the convex portion of the second press member cannot be inserted inside the skirt portion, the degree of deformation of the deformed portion can be reduced in the preliminary repair step, so the repair step The convex part of the second press member can be inserted inside the skirt part. Therefore, the work of hitting the deformed portion with a hammer or the like can be omitted even for a container having a large degree of deformation, so that the burden on the operator can be further reduced.

  In addition, in the above description, in order to make an understanding of this invention easy, the reference sign of the accompanying drawing was attached in parenthesis, but this invention is not limited to the form of illustration by it.

  As described above, according to the present invention, by sandwiching the skirt portion by the convex portion of the second press member and the concave portion of the first press member, the deformation of the skirt portion of the container to be repaired can be repaired. The deformation of the skirt portion can be repaired more easily than in the past. Thereby, the quantity of reusable containers can be increased significantly.

As shown in FIG. 3, the beer barrel 100 is provided with a base 101 a for taking out beer from the inside, a main body 101 filled with beer as contents, and a cylindrical upper portion extending upward from the main body 101. A skirt 102 and a cylindrical lower skirt 103 extending downward from the main body 101 are provided. Hereinafter, when it is not necessary to distinguish the upper skirt 102 and the lower skirt 103, they are simply referred to as a skirt. The main body 101, the upper skirt 102, and the lower skirt 103 are made of metal such as stainless steel. Therefore, when an impact is applied to the skirts 102 and 103 during the distribution process, the skirts 102 and 103 may be deformed.

  As shown in FIG. 1, the upper surface and the bottom surface of the main body 101 are each formed of a spherical mirror surface with the center portion protruding outward. The upper skirt 102 includes a cylindrical body portion 102a, and a curl portion 102b in which a member forming the body portion 102a is rounded inward over the entire circumference at the upper end portion. A hole 102c is provided in the trunk portion 102a of the upper skirt 102 so that an operator can put a hand during transportation. Similarly to the upper skirt 102, the lower skirt 103 also includes a cylindrical body portion 103a and a curled portion 103b. When the beer barrel 100 is stacked, the curled portion 103b of the lower skirt 103 fits inside the curled portion 102b of the upper skirt 102, in other words, the curled portion 103b of the lower skirt 103. A step 103 c is provided so that the outer diameter is substantially the same as the inner diameter of the curled portion 102 b of the upper skirt 102.

  As shown in FIG. 1, the beer barrel 100 to be repaired with the skirt deformed is placed on the container repair device 1 in a state where the skirt is deformed sideways, and the deformed portion of the skirt of the beer barrel 100 to be repaired (hereinafter referred to as “below”). The deformed portion is repaired by sandwiching the press receiving portion 21 and the press portion 23). The container repairing apparatus 1 includes a gantry 10 with wheels 11, a press mechanism 30 for repairing a deformed portion, a deformed portion of the skirt on the press mechanism 30, and a beer barrel 100 in a state where the beer barrel 100 is tilted sideways. A container fixing mechanism 20 is provided as a restraining means for restraining the main body 101 of the beer barrel 100 so as to be fixed.

  The container fixing mechanism 20 is disposed on the gantry 10 so as to support the main body 101 of the beer barrel 100 that has been laid down from below, the main body support 21 provided on the gantry 10, and provided on the gantry 10. A pair of container pressers 23 as container presser members supported by the guide 22 so as to be movable up and down, and a restraining position P1 for pressing the main body 101 of the beer barrel 100 placed on the main body support 21 and the restraint position P1 An air cylinder 24 is provided as a pressing member driving actuator means for driving the container presser 23 between the restraint releasing position P2 where the pressing is released. The main body support portion 21 includes a plurality of support blocks 21 a on which the main body portion 101 of the beer barrel 100 is placed, and a fixing member 21 b that fixes the support block 21 a to the gantry 10. As shown in FIG. 2, the plurality of support blocks 21a are mounted on the support member 21b so that the support surface 21c of the main body support portion 21 formed by these support blocks 21a gradually increases from the central portion toward both sides. 10 respectively. Therefore, the support surface 21c of the main body support portion 21 is formed in a shape in which the central portion is recessed. By fixing each support block 21a in this way, it is possible to prevent the beer barrel 100 to be repaired from rolling on the support surface 21c. The main body support portion 21 is provided at a height at which an operator can easily work, in other words, at a height at which the operator can easily lift the beer barrel 100. As such a height, for example, a height of about 90 cm from the floor surface is set.

  As shown in FIGS. 1 and 2, the pair of container holders 23 are arranged in the axial direction of the beer barrel 100 placed on the main body support portion 21 at the lower end of the support 23 a supported by the guide 22 and the support 23 a. And a cylindrical fixed pad 23b provided to extend. The pair of container holders 23 are connected by a connecting member 23c, and the air cylinder 24 drives the pair of container holders 23 in the vertical direction by moving the connecting member 23c up and down. The pair of container holders 23 are repaired in which the fixed pad 23b of one container holder 23 and the fixed pad 23b of the other container holder 23 are placed on the main body support portion 21 when driven to the restraining position P1 by the air cylinder 24. It is located symmetrically with respect to the axis of the target beer barrel 100, and is provided so that the side surfaces of the beer barrel 100 can be pressed by the fixing pads 23b of the container pressers 23, respectively. Therefore, the position of the beer barrel 100 placed on the main body support portion 21 can be fixed by moving the pair of container pressers 23 to the restraining position P1.

  The press mechanism 30 is fixed to the gantry 10 so that the concave portion 31a is disposed at substantially the same height as the support surface 21c of the main body support portion 21 and the main body 101 is restrained by the container fixing mechanism 20. A press receiving member 31 as a first press member in which a deformed portion of the skirt of the beer barrel 100 is arranged, and a convex portion 33a are provided so as to face the concave portion 31a of the press receiving member 31, and a guide rail 32 as a guide means. Are provided with a press member 33 as a second press member supported so as to be movable up and down, and a hydraulic cylinder 34 as actuator means for driving the press member 33 in the vertical direction. Since the hydraulic cylinder 34 may be a well-known one that can extend and contract the piston rod 34a by hydraulic pressure, detailed description thereof is omitted.

  The press receiving member 31 and the press member 33 will be described with reference to FIGS. 4 and 5. 4 is an enlarged view showing a part of the press mechanism 30. FIG. 5 is a perspective view of the portion shown in FIG. As shown in FIG. 5, the press receiving member 31 has a recess 31 a disposed on the outer peripheral side of the deformed portion of the skirt. Also, as shown in FIG. 4, the press receiving member 31 is a base member 35 as a first fixing portion fixed to the gantry 10, and is attachable to and detachable from the base member 35 and is provided with a recess 31a. A lower jig 36 as one jig portion is provided. The lower jig 36 is fixed to the base member 35 with pins 37. 6 and 7 are enlarged views of the lower jig 36. FIG. 6 is a view of the lower jig 36 as viewed from the left side of FIG. 7, and FIG. 7 is a cross-sectional view of the lower jig 36 taken along the line VII-VII of FIG. The lower jig 36 is for repairing the deformation of the upper skirt 102 of the beer barrel 100 shown in FIG.

  As shown in FIG. 6, on the upper surface of the lower jig 36, there are provided two curved surfaces 36a and 36b that are recessed so that the center portion is lowest. The curved surface 36 a is a portion that becomes the recess 31 a when the lower jig 36 is attached to the base member 35. The curved surface 36a is recessed so that the cross section becomes a concave curved surface with the center at the bottom as shown in FIG. 6, and is formed to extend in one direction as shown in FIG. As shown in FIG. 6, the curved surface 36 a is formed with a diameter R <b> 1 that is smaller than the outer diameter Rout of the trunk portion 102 a of the upper skirt portion 102 of the beer barrel 100. Therefore, when the trunk portion 102a of the upper skirt portion 102 that is not deformed is placed on the curved surface 36a, a gap Δh is generated between the curved surface 36a and the trunk portion 102a at the central portion. For example, when the deformation of the body portion 102a of the upper skirt portion 102 is repaired, a value at which the return of the repaired portion and the gap Δh are substantially the same is set as the diameter R1 of the curved surface 36a. Since the return of the repaired portion varies depending on the size, shape, material, and the like of the upper skirt portion 102, the diameter R1 of the curved surface 36a may be set to an appropriate value according to these parameters. The curved surface 36b is formed with a smaller diameter than the curved surface 36a. Therefore, as shown in FIG. 7, a step 36c is formed at the boundary between the curved surface 36a and the curved surface 36b. The step 36 c is formed with the same diameter Rc as the diameter of the curled portion 102 b of the upper skirt 102. Therefore, when the upper skirt 102 of the beer barrel 100 is arranged on the press receiving member 31 as shown in FIG. 4, the curled portion 102b of the upper skirt 102 can be brought into contact with the step 36c without any gap. Position adjustment holes 36d and 36d for fitting a protrusion (not shown) provided on the base member 35 to align the position of the lower jig 36 with respect to the base member 35 on the lower surface of the lower jig 36, and a base member Pin insertion holes 36e and 36e into which pins 37 are inserted when the lower jig 36 is fixed to 35 are provided.

  6 and 7 show the lower jig 36 for the upper skirt 102. In addition to this, a plurality of lower jigs having recesses having a shape corresponding to the shape of the skirt to be repaired are prepared. For example, as shown in FIG. 3, since the upper skirt 102 and the lower skirt 103 have different shapes, it is difficult to repair the deformation of the lower skirt 103 with the lower jig 36 for the upper skirt 102. Therefore, a lower jig having a recess having a shape corresponding to the shape of the outer periphery of the lower skirt 103 is prepared, and when the deformation of the lower skirt 103 is repaired, the lower jig is attached to the base member 35 for repair. . Similarly, when repairing the deformation of the skirt of the beer barrel 100 having a different skirt shape, a lower jig having a concave portion corresponding to the shape of the skirt of the beer barrel 100 to be repaired is prepared, and the base member 35 is prepared. The lower jig is attached to repair the deformation of the skirt of the beer barrel 100. Thus, in the container repairing apparatus 1 of the present invention, even when repairing a skirt having a different shape, it is not necessary to replace the entire press receiving member 31, and it is possible to cope with only the replacement of the lower jig 36. Moreover, since the lower jig 36 is fixed to the base member 35 with the pins 37 as described above, the lower jig 36 can be replaced relatively easily. Therefore, it is possible to reduce the time required for the container repair device 1 to correspond to skirts having different shapes.

  The press member 33 has a convex portion 33 a that extends in the same direction as the concave portion 31 a of the press receiving member 31 and is provided so as to be opposed to the press receiving member 31. As shown in FIGS. 4 and 5, the press member 33 is detachable from the slide portion 38 as a second fixed portion supported by the guide rail 32 so as to be movable up and down, and the slide portion 38. And the upper jig | tool 39 as a 2nd jig | tool part in which the convex part 33a is provided is provided. An intermediate member 40 (see FIG. 4) that is fitted into a fitting hole (not shown) of the slide portion 38 when the upper jig 39 is fixed to the slide portion 38 is attached to the upper jig 39. The upper jig 39 is fixed to the slide portion 38 by inserting the intermediate member 40 into the fitting hole of the slide portion 38 and penetrating the slide portion 38 and the upper jig 39. As shown in FIG. 4, the piston rod 34 a of the hydraulic cylinder 34 is connected to the slide portion 38. 8 and 9 are enlarged views of the upper jig 39. FIG. 8 is a view of the upper jig 39 as viewed from the left side of FIG. 9, and FIG. 9 is a cross-sectional view of the upper jig 39 taken along the line IX-IX in FIG. The upper jig 39 is for repairing the deformation of the upper skirt 102 of the beer barrel 100 shown in FIG. 3 in the same manner as the lower jig 36 described above.

  On the lower surface of the upper jig 39, there is provided a curved surface 39a whose cross section is a convex curved surface having a central portion as a tip as shown in FIG. 8, and extending in one direction as shown in FIG. The curved surface 39 a is a portion that becomes the convex portion 33 a when the upper jig 39 is attached to the slide portion 38. The diameter R2 of the curved surface 39a is a value that allows the trunk portion 102b to be pressed against the concave portion 31a when the convex portion 33a and the concave portion 31a sandwich the trunk portion 102b of the upper skirt 102, for example, the curved surface of the lower jig 36. The same value as the diameter R1 of 36a is set. The diameter R2 of the curved surface 39a is not limited to this value. For example, a value smaller than the diameter R1 of the curved surface 36a of the lower jig 36 may be set. With such a value, when the body part 102b of the upper skirt 102 is sandwiched between the convex part 33a and the concave part 31a, the body part 102b can be pressed against the concave part 31a. As shown in FIG. 1, the upper jig 39 inserts the tip portion into the inner peripheral side of the upper skirt 102, so that the length L of the curved surface 39 a is smaller than the length of the trunk portion 102 b of the upper skirt 102, For example, a length of about 80% of the length of the trunk portion 102b is set. Further, a pocket portion 39b is provided on the lower surface of the upper jig 39 to accommodate the curled portion 102b of the upper skirt 102 when the deformed portion of the upper skirt 102 is sandwiched between the press receiving member 31 and the press member 33. ing. Therefore, the pocket portion 39b is formed to have a diameter slightly larger than the outer diameter of the curled portion 102b of the upper skirt 102. Further, the pocket portion 39b is arranged so as to accommodate the curled portion 102b when the curled portion 102b of the upper skirt 102 is arranged so as to contact the step 36c of the lower jig 36 as shown in FIG. Provided on the jig 39.

  As shown in FIGS. 8 and 9, a pin insertion hole 39 c into which the pin 41 is inserted when the upper jig 39 is fixed to the slide portion 38 is provided on the upper surface of the upper jig 39. Further, an insertion groove 39d into which the intermediate member 40 is inserted and a bolt for fixing the intermediate member 40 to the upper jig 39 are screwed into the side surface of the upper jig 39 that is disposed on the slide portion 38 side. Screw holes 39e are provided. As shown in FIG. 9, among the side surfaces of the upper jig 39, the side surface that is inserted into the inner periphery of the upper skirt 102 and faces the upper surface of the beer barrel 100 is arranged on the slide portion 38 side from the middle toward the upper side. Inclined to recede toward the side. By inclining the side surface facing the upper surface of the beer barrel 100 in this manner, the distance that the upper jig 39 can move inside the upper skirt 102 without being in contact with the upper surface of the beer barrel 100 can be increased.

  Similarly to the lower jig 36, the upper jig 39 includes a plurality of upper jigs having convex portions having a shape corresponding to the shape of the skirt to be repaired in addition to the one for the upper skirt 102 shown in FIGS. Be prepared. Further, as the upper jig 39, a plurality of upper jigs having a convex portion corresponding to the part of the skirt to be repaired are prepared. For example, as shown in FIG. 3, when repairing the portion of the body portion 102a where the hole 102c is provided, the convex portion 33a considering the portion around the hole 102c is required. Therefore, when repairing this portion of the upper skirt portion 102, an upper jig having a convex portion corresponding to the shape of the trunk portion 102a provided with the hole 102c is prepared, and this upper jig is used as the slide portion. 38. Similarly, when the deformation of the beer barrel 100 having a different skirt shape is repaired, the beer barrel 100 is similarly replaced with an upper jig having a convex portion corresponding to the shape of the skirt of the beer barrel 100. Similarly to the press receiving member 31, since the upper jig 39 can be attached to and detached from the slide portion 38, it is not necessary to replace the entire press member 33 even when repairing a skirt having a different shape. Therefore, it is possible to reduce the time required for the container repair device 1 to correspond to skirts having different shapes. Further, since the upper jig 39 is fixed to the slide portion 38 with the pins 41, the upper jig 39 can be replaced relatively easily.

  Returning to FIG. 1, the description of the container repairing apparatus 1 will be continued. The container repair device 1 includes a compressed air control device 50 for controlling the compressed air supplied to the air cylinder 24 and a hydraulic control device 60 for controlling the hydraulic pressure supplied to the hydraulic cylinder 34. FIG. 10 shows an outline of the compressed air control device 50 and the hydraulic pressure control device 60 in the container repairing apparatus 1. The compressed air control device 50 is interposed between the compressed air supply source and the air cylinder 24, and supplies the compressed air supplied to the air cylinder 24 so that the air cylinder 24 extends and the container retainer 23 moves to the restraining position P1. A compressed air control valve 51 is provided that can be switched between a lowered position to be controlled and an elevated position for controlling the compressed air supplied to the air cylinder 24 so that the air cylinder 24 contracts and the container retainer 23 moves to the restraint release position P2. Yes.

  The hydraulic control device 60 sends the oil in the oil tank 61 to the hydraulic cylinder 34 by the hydraulic pump 62. Between the hydraulic pump 62 and the hydraulic cylinder 34, a hydraulic control valve 63 that can be switched between a press lowered position where the piston rod 34a of the hydraulic cylinder 34 extends and a press raised position where the piston rod 34a of the hydraulic cylinder 34 contracts is provided. . In addition, the hydraulic control device 60 includes a safety valve 64 that opens when the hydraulic pressure of the hydraulic cylinder 34 becomes equal to or higher than a predetermined pressure set in advance to reduce the hydraulic pressure in the hydraulic cylinder 34. As the predetermined pressure of the safety valve 64, for example, a pressure is set such that an excessive force is applied to the press member 33 and the parts of the container repairing apparatus 1 such as the beer barrel 100, the press member 33, and the press receiving member 31 are not damaged. . Since such a pressure changes according to the structure of the container repair device 1 and the material of each member, the predetermined pressure may be appropriately set according to the structure of the container repair device 1 and the material of each member.

  Moreover, the container repair apparatus 1 is provided with the control apparatus 70 for controlling the operation | movement of the compressed air control valve 51, and the operation | movement of the hydraulic control valve 63, as shown in FIG.1 and FIG.10. The control device 70 includes a plurality of switches 72 operated by an operator, an operation panel 71 provided with a display 73 for displaying the state of the container repairing device 1, for example, the operation status of the press member 33, the valves 51, And an operation control unit 74 that controls the operation of 63. As a plurality of switches provided on the operation panel 71, for example, a lowering switch for moving the container presser 23 to the restraint position P1, a lift switch for moving the container presser 23 to the restraint release position P2, and a press member 33 are lowered. For example, a press switch for raising and a press release switch for raising the press member 33 are provided. When the operator operates one of the switches on the operation panel 71, the operation control unit 74 controls the operation of the compressed air control valve 51 and the operation of the hydraulic control valve 63 according to the switch. For example, when the operator operates the press switch, the hydraulic control valve 63 is switched to the press lowered position so that the hydraulic cylinder 34 extends and the press member 33 descends. The control device 70 may be realized by a computer unit including a microprocessor and peripheral devices such as RAM and ROM necessary for its operation, or may be realized by a hardware control circuit.

  Next, a container repair method using the container repair apparatus 1 will be described with reference to FIGS. 4, 11, and 12. FIG. 11 shows an example of a beer barrel 100 in which the upper skirt 102 is deformed. As shown in FIG. 11, the beer barrel 100 is deformed by bending a part 102d of the upper skirt 102 inward. When repairing the deformed portion (deformed portion) 102d of the upper skirt 102 of the beer barrel 100, first, as preparation before repair, the air cylinder 24 is operated to move the container presser 33 to the restraint release position P2. Further, when the beer barrel 100 is placed on the main body support portion 21 and the deformed portion 102d is disposed in the concave portion 31a of the press receiving member 31, the upper jig 39 of the press member 33 is located on the inner peripheral side of the upper skirt 102. Further, the height of the press member 33 is adjusted so that the press member 33 is disposed below the base 101a without contacting the top surface of the base 101a and the main body 101. If it is this position, since the convex part 33a of the press member 33 can be spaced apart from the deformation | transformation part 102d, this position is set to the cancellation | release position P3. After these preparations are completed, a position fixing step S1 for fixing the position of the beer barrel 100 by the container fixing mechanism 20 is performed. In the position fixing step S <b> 1, the beer barrel 100 is placed on the main body support portion 21 so that the deformed portion 102 d is positioned in the concave portion 31 a of the press receiving member 31 as shown in FIG. 4. By placing the beer barrel 100 in this way, the vertical direction of the beer barrel 100 can be matched with the direction in which the convex portion 31a and the concave portion 33a extend. At this time, the position of the beer barrel 100 is adjusted so that the curled portion 102 b of the deformed portion 102 d is disposed above the step 36 c of the press receiving member 31. Thereby, the beer barrel 100 can be adjusted to the position shown in FIG. Thereafter, the air cylinder 24 is operated to move the container presser 33 to the restraining position P1. Thereby, the beer barrel 100 can be fixed to the main body support portion 21.

  Next, repair process S2 is implemented. In the repair step S2, the hydraulic cylinder 34 is operated to drive the press member 33 downward, and the deformed portion 102d is sandwiched between the concave portion 31a of the press receiving member 31 and the convex portion 33a of the press member 33 as shown in FIG. Press at. Therefore, the position of the press member 33 at this time is the repair position P4. Thereafter, the press member 33 is held at the repair position P4 for several seconds (for example, 3 seconds). In other words, the deformed portion 102d is pressed for several seconds by the concave portion 31a and the convex portion 33a. The time for maintaining the press member 33 at the repair position P4 is set in consideration of the return of the deformed portion 102d after repair, and is increased when it is determined that the return after repair is large. At this time, as shown in FIG. 12, the curled portion 102 b of the upper skirt 102 is accommodated in the pocket portion 39 b of the upper jig 39. Therefore, it is possible to suppress the curled portion 102b from being crushed.

  After repair process S2 is complete | finished, the hydraulic cylinder 34 is operated and the press member 33 is moved to the cancellation | release position P3. Thereafter, the air cylinder 24 is operated to move the container presser 33 to the restraint release position P2. After releasing the pressing by the container holder 23, the repaired beer barrel 100 is lowered from the main body support portion 21. When there are a plurality of deformed portions 102d in the upper skirt 102, the beer barrel 100 is rotated in the circumferential direction so that another deformed portion 102d to be repaired after the release of pressing is located in the recess 31a of the press receiving member 31. . Thereafter, the position of the beer barrel 100 is fixed by the container fixing mechanism 20, and the repair process S2 is performed again. Then, this procedure is repeatedly executed, and after all the repairs of the plurality of deformed portions 102d are completed, the repaired beer barrel 100 is lowered from the main body support portion 21.

  As described above, the concave portion 31a of the press receiving member 31 is formed with a curved surface having a diameter R1 smaller than the outer diameter Rout of the upper skirt 102, and the convex portion 33a of the press member 33 has the same diameter R2 as the diameter R1 of the concave portion 31a. It is formed with a curved surface. Therefore, the deformed portion 102d can swell outward than the state before deformation when sandwiched between the concave portion 31a and the convex portion 33a, in other words, can be in a state of warping outward. Thereby, it is possible to repair the deformed portion 102d in consideration of the return after the repair. Therefore, the state of the deformed portion 102d can be returned almost to the state before the deformation. Thus, according to the container repair device 1 of the present invention, after the beer barrel 100 is placed on the main body support 21 and the position is fixed, the deformed portion 102d can be repaired only by operating the hydraulic cylinder 34. The skirt can be repaired more easily than before. Further, since the deformed portion 102d is repaired by the hydraulic cylinder 34, it is not necessary to hit the deformed portion 102d with a hammer or the like. Therefore, the burden on the operator can be reduced.

  The method for repairing the deformed portion 102d using the container repair device 1 of the present invention is not limited to the method described above. For example, in the repair process S2, the press member 33 is not moved from the release position P3 to the repair position P4 at a time, but is first set between the release position P3 and the repair position P4, and gradually approaches the repair position P4. The press member 33 may be reciprocated a plurality of times between the target position to be changed and the release position P3, and then the press member 33 may be moved to the repair position P4. When the plate forming the skirt is thick or depending on the degree of deformation of the deformed portion 102d, if the press member 33 is moved from the release position P3 to the repair position P4 at a time, excessive force is applied to the deformed portion 102d at a time. In addition, the skirt may be damaged. Therefore, first, the press member 33 is reciprocated a plurality of times between the release position P3 and the target position that is gradually changed to the repair position P4, and the deformed portion 102d is gradually returned to the shape before the deformation, thereby deforming. It is possible to prevent an excessive force from being applied to the portion 102d. Therefore, it is possible to prevent the skirt from being damaged during repair. When the control device 70 is realized by a computer unit, a control program for the hydraulic control valve 63 for realizing the operation procedure of the press member 33 in the above-described preliminary repair process S3 is stored in the ROM of the control device 70. In addition, the operation of the press member 33 may be controlled by executing this program.

  Further, for example, when the deformed portion 102d is bent to the inner peripheral side to such an extent that the upper jig 39 of the press member 33 cannot be inserted inside the upper skirt 102, before the above-described position fixing step S1, FIG. As shown in FIG. 4, a pre-repair step S3 may be added in which the convex portion 33a of the pressing member 33 pushes the curled portion 102b of the deformed portion 102d and pushes the deformed portion 102d outward.

  In the pre-repair step S3, first, the deformed portion 102d is on the concave portion 31a of the press receiving member 31, and when the press member 33 is moved downward, the beer barrel is arranged such that the convex portion 33a hits the curled portion 102b of the deformed portion 102d. 100 is placed on the main body support 21 while being tilted. Thereafter, the air cylinder 24 is operated to move the container presser 33 to the restraint position P1, thereby fixing the beer barrel 100 at that position. After fixing the position of the beer barrel 100, the hydraulic cylinder 34 is operated to drive the press member 33 downward, and push the deformed portion 102d outward. At this time, the press member 33 is driven downward to such an extent that the outer periphery of the deformed portion 102 d contacts the recess 31 a of the press receiving member 31. Thereafter, the hydraulic cylinder 34 is operated to drive the press member 33 upward, and the correction of the deformed portion 102d is completed. This correction may be repeated until the upper jig 39 of the pressing member 33 can be inserted inside the upper skirt 102. Thereafter, the above-described position fixing step S1 and repair step S2 are performed.

  As described above, the pre-repair step S3 is performed before the position fixing step S1 and the repair step S2, so that the deformed portion 102d can be inserted into the upper skirt 102 so that the upper jig 39 cannot be inserted inside the upper skirt 102. Even for the beer barrel 100 bent to the peripheral side, the deformation can be repaired only by the container repair device 1 of the present invention. This eliminates the need for the operator to tap with a hammer or the like to reduce the degree of deformation of the deformed portion 102d, thereby further reducing the burden on the operator.

  The present invention is not limited to the form described above, and may be implemented in various forms. For example, the container repaired by the container repairing apparatus of the present invention is not limited to a beer barrel. In the container repair apparatus of this invention, you may repair various containers which have a skirt part extended to an up-down direction like a beer barrel.

  The shape of the concave portion of the press receiving member is not limited to the shape of the above-described form. The concave portion only needs to be formed such that when the deformed portion is sandwiched between the convex portion of the press member and the concave portion of the press receiving member, the deformed portion swells to the outer peripheral side from the state before the deformation. Therefore, for example, the concave curve of the cross section of the concave portion may be a combination of curves having different curvatures. In this case, it is only necessary that at least the central portion serving as the bottom of the concave curve is a curved surface formed with a diameter smaller than the diameter of the outer periphery of the skirt portion. For example, a curved surface with a diameter smaller than the outer diameter of the skirt is provided at the center so that a gap is formed between the recessed portion and the skirt, and a curved surface with a diameter so that the skirt smoothly contacts the recessed portion is provided at both ends. These curved surfaces may be connected by curved surfaces whose diameters gradually increase from the center toward both ends. By providing such a curved surface at the central portion, when the deformed portion is sandwiched between the convex portion and the concave portion, the deformed portion can be expanded to the outer peripheral side as compared with the state before the deformation.

  In the embodiment described above, the press receiving member having the concave portion is fixed to the gantry and the press member having the convex portion is provided so as to be movable in the vertical direction, but the press member having the convex portion is fixed to the gantry and the concave portion is You may provide the press receiving member which has so that a recessed part may oppose a convex part and to be able to move to an up-down direction. Also in this case, the deformed portion is sandwiched between the concave portion and the convex portion in the same manner as described above, whereby the deformed portion can be repaired. Further, as long as the deformed portion can be sandwiched between the convex portion and the concave portion, both the press receiving member and the press member may be provided so as to be movable in the vertical direction.

  In the above-described embodiment, the container is fixed in a state where it is laid down and repaired by sandwiching the deformed portion from above and below, but the state of fixing the container and the direction of sandwiching the deformed portion are not limited thereto. For example, at least one of the press receiving member and the pressing member is provided so as to be movable in the left-right direction, and the concave portion of the press receiving member is disposed on the outer peripheral side of the deformed portion, and the convex portion of the press member is disposed on the inner peripheral side of the deformed portion. The container may be fixed in a standing state. Also in this case, the deformed portion can be pressed by sandwiching the deformed portion between the concave portion of the press receiving member and the convex portion of the press member in the same manner as described above, so that the deformed portion can be repaired easily.
