Description

  The present invention relates to a bottle body rotation mechanism of an abrasive spraying apparatus, and more particularly, to a frosting apparatus for matting a glass bottle surface by a sandblasting method.

  It is common to produce a beautiful finish with enhanced decorativeness by forming a cloudy matte surface on the surface of a glass product such as a glass bottle. This processing method includes a chemical frost method (chemical frost processing) that corrodes the surface of a glass product using hydrofluoric acid or the like, and a sand blast method (sand blast treatment) in which a high-hardness abrasive such as alumina is sprayed on the surface of the glass product. Two types are typical.

  Since the chemical frost method uses highly corrosive hydrofluoric acid, problems such as safety management and waste liquid treatment of workers are regarded as important, and burden is required for each countermeasure. Therefore, in recent years, sandblasting methods that do not use deleterious substances have been the mainstream when frosting glass products (see, for example, Patent Documents 1, 2, 3, 4, 5, and 6).

  In this sandblasting method, for example, a glass product is fixed to a predetermined pedestal, an abrasive is sprayed on the surface of the glass product, and then the excess abrasive is removed and washed, and the process is completed (see Patent Document 7, etc.). In the conventional sandblasting method, processing was always performed on a small scale. For that reason, the automation of processing is not perfect, and there are many parts that rely on human hands.

  For this reason, in the processing of the frost treatment by the sandblast method, it is not easy to increase the number of treatments per unit time. In particular, when glass products with high demand such as glass bottles are subjected to a frost treatment by the sandblast method, improvement of productivity is a problem.

  Thus, when a glass bottle having a high demand is subjected to a frosting process by the sandblasting method, a series of sandblasting processes can be continuously performed, and an apparatus having an improved processing capability has been desired. In particular, an abrasive spray processing apparatus (sand blasting apparatus) is required to be improved so that a plurality of glass bottles can be attached to the apparatus at once and removed smoothly.

  In particular, when the sandblasting method is used, the amount of the abrasive to be sprayed becomes non-uniform unless the glass bottle to be treated is continuously moved. Due to the difference in polishing amount on the surface of the glass bottle, the quality of the finished product varies. Therefore, when performing a frost process by the sandblast method on a mass production scale, a simple mechanism that finishes to an equal quality while reducing the bias of the abrasive spraying has been desired.

The turntable 101 is equally divided into three at the central angle, and in the drawing, the turntable 101 is partitioned in the order of the first partition 110, the second partition 120, and the third partition 130 in the clockwise direction. In each of the partition sections 110, 120, and 130, a bottle inverted holding section 200 is formed for each partition section for detachably holding a plurality of bottle bodies w (seven in this embodiment). . In the embodiment, the “bottle holding part” for holding the bottle body holds the bottle body in an inverted state. For this reason, the invention will be illustrated and described below as a “bottle inverted holding portion”.

  The first partition portion 110 of the turntable 101 is a first bottle inverted holding portion 201, the second partition portion 120 is a second bottle inverted holding portion 202, and the third partition portion 130 is a third bottle inverted holding portion 203. The turntable 101 repeats intermittent rotational movement once every predetermined time of 2 to 5 seconds by 120 °. Therefore, each partition part can move to the next position in order. The intermittent rotational movement of the embodiment is clockwise. Corresponding to the position where the turntable 101 is intermittently rotated and stopped, a bottle carrying in / out unit 140, an abrasive spray unit 150, and an air spray unit 160 are arranged.

  The main structure of the carry-in machine 20 and the carry-out machine 30 in the carry-in / carry-out mechanism 10 will be described with reference to FIGS. 4 and 5. In addition, since the carrying-in machine 20 and the carrying-out machine 30 are comprised from the same member, in the figure, the other is substituted by one description.

  As shown in FIG. 4, a chuck unit 25 is connected via a support arm 26 below the elevating unit 14 of the loading machine 20 that is one side of the loading / unloading mechanism 10. The chuck unit 25 shown in the figure is equipped with seven chuck portions 21. One chuck portion 21 is provided with press contact portions 22 and 23 for gripping the bottle side surface from two opposing directions. The pressure contact portions 22 and 23 can move the bottle body by moving forward and backward. The movable direction of the press contact portion in the embodiment is the same as the transfer direction of the conveyor 5. It is good also as a direction orthogonal to a transfer direction. The unloader 30 will be described as a chuck portion 31, a chuck unit 35, and a support arm 36.

  The situation of feeding the bottle body w to the turntable 101 will be described mainly with reference to FIGS. 4 and 5. In the embodiment, an interval adjusting device (not shown) such as a wheel is appropriately attached upstream of the conveyor 5, and the bottle bodies w are transferred in a row on the conveyor 5 at regular intervals. In FIG. 5, reference numeral 250 denotes an extension member actuating device, and 252 denotes a pressing portion, which will be described in detail with reference to FIGS.

  When a plurality of bottle bodies reach a predetermined position on the conveyor 5, the transfer of the conveyor 5 is once stopped. Each chuck portion 21 of the chuck unit 25 provided in the loading machine 20 of the loading / unloading mechanism 10 in contact with the conveyor 5 is aligned immediately above the bottle body w on the conveyor 5. At this time, the pressure contact portions 22 and 23 of each chuck portion 21 are in an open state. The chuck unit 25 is lowered as it is, the bottle body w is accommodated between the pressure contact portions 22 and 23, and the bottle body w is gripped by the pressure contact portion.

  The support arm 26 is provided with an appropriate rotation motor (not shown). Therefore, after the chuck portion 21 (chuck unit 25) holding the bottle body w is raised to a predetermined position, the chuck unit 25 is rotated halfway in the direction of the solid line arrow (Da) in FIG. The bottle body is inverted from the upright state to the inverted state.

  Subsequently, as shown in FIG. 5, the chuck portion 21 (chuck unit 25) that holds the bottle body in an inverted state is one partition portion on the turntable 101 located at the opening 109 of the abrasive spraying apparatus. In the figure, the first partitioning section 110 is positioned right above the first bottle inverted holding section 201 (200). Thereafter, the chuck part 21 (chuck unit 25) is vertically lowered, and the gripped bottles w are inserted into the bottle inverted holding parts 201 at the corresponding positions, and the bottles are held in the inverted state by the holding parts. Is done. Thus, the feeding of the bottle body is completed.

  After the holding of the bottle body to the bottle inverted holding portion is completed, the gripping by the press contact portions 22 and 23 of the chuck portion 21 is released. The chuck portion 21 (chuck unit 25) of the carry-in machine 20 moves up and returns to the position where the bottle body is lifted from the conveyor 5 in FIG. The feeding of the bottle body to the second bottle inverted holding part 202 in the second partition part 120 and the third bottle inverted holding part 203 in the third partition part 130 is the same as shown in the figure.

  Next, how the bottle body is sent out from the bottle inverted holding unit 200 in the turntable 101 to the conveyor 5 will be described. As shown in FIG. 5, the chuck portion 31 (chuck unit 35) provided in the unloader 30 is one partition portion on the turntable 101 located in the opening 109 of the abrasive spraying apparatus, the first partition in the drawing. Positioning is performed immediately above the first bottle inverted holding portion 201 (200) in the portion 110.

  At this time, the pressure contact portions 22 and 23 of each chuck portion 31 are in an open state. The chuck unit 35 is lowered as it is, the bottle body w is accommodated between the press contact portions 22 and 23, and the bottle body w is gripped by the press contact portion. The support arm 36 is also provided with an appropriate rotation motor (not shown), and after the chuck portion 31 (chuck unit 35) holding the bottle body w has been raised to a predetermined position, the chuck unit 35 is shown by a solid line in FIG. Half-turn in the direction of the arrow (Db). The bottle body is inverted from the inverted state to the upright state.

  Returning to FIG. 4, each chuck portion 31 of the chuck unit 35 is aligned immediately above a predetermined position on which the bottles on the conveyor 5 are placed. The chuck unit 35 is lowered as it is, the gripping by the press contact portions 22 and 23 is released, and the bottle body w in the upright state is placed on the conveyor 5. This completes the delivery of the bottle. The delivery of the bottle body to the second bottle inverted holding section 202 in the second partition section 120 and the third bottle inverted holding section 203 in the third partition section 130 is the same as shown in the figure.

  In particular, the operation of the unloader 30 is performed prior to the operation of the loader 20. Prior to the above-described operation by the carry-in machine 20, the carry-out machine 30 grips and collects the bottle after finishing the sandblasting process described later from the bottle inverted holding part 200 on the turntable 101 located at the opening 109. This is because it is possible to newly accept an unprocessed bottle from the carry-in machine 20. Moreover, since the carry-in / carry-out mechanism 10 includes the carry-in machine 20 and the carry-out machine 30, the operation of the carry-in machine 20 and the carry-out machine 30 is avoided.

  Alignment and half-rotation of the translation unit 12, the crossing unit 13, the elevating unit 14, and the chuck units 25 and 35 provided in the carry-in machine 20 and the carry-out machine 30 of the carry-in / out mechanism 10 and interference with each other. When performing the avoided operation, the control motor used for these drive controls is appropriately executed in conjunction with the intermittent rotational movement of the turntable 101 based on appropriate sequence control. The operation | movement aspect of Table 1 is an example of the time series of the operation | movement in the loading machine 20 and the unloading machine 30 of the loading / unloading mechanism 10 of an Example. The time axis is the flow from top to bottom. The carry-in machine 20 and the carry-out machine 30 are controlled by shifting the timing of carry-in to the turntable and carry-out from the turntable. The operations in Table 1 are executed each time the turntable 101 is intermittently rotated and one of the partition portions is stopped at the opening 109.

  The abrasive spraying unit 150 and the air spraying unit 160 of the abrasive spraying apparatus 100 according to the embodiment will be described with reference to FIGS. 1 and 2. An abrasive spraying part 150 is disposed at the lower part of the abrasive supply duct 171 in FIG. 1, and an air spraying part 160 is disposed at the lower part of the air supply duct 172 (see FIG. 2). The abrasive is supplied from the abrasive supply duct 171 to the abrasive spraying device 155 in the abrasive spraying unit 150. Further, blow air for blowing off the abrasive is supplied from the air supply duct 172 to the air blowing portion 165 in the air blowing portion 160. The abrasive supply duct 171 and the air supply duct 172 may be configured as a single duct or may be configured for each individual supply hose.

  In the carry-in / carry-out unit 140 of the embodiment, the bottle body w is in an inverted state with respect to the bottle inverted holding unit 200 (201, 202, 203) of the turntable 101, and holds 7 bottles per bottle inverted holding unit. The bottle body is held upside down by a bottle inverted holding portion (in FIG. 2, the first partition inverted holding portion 201 is illustrated in the first partition 110). Thereafter, the first partition portion 110 reaches the abrasive spraying portion 150 by moving intermittently by 120 °, and stops here for a predetermined time. In the meantime, the abrasive is sprayed from the abrasive spraying device 155. As can be understood from the side view of FIG. 6, the abrasive spraying device 155 of the embodiment has five abrasive spraying portions 155a, 155b, 155c, 155d, and 155e in the vertical direction with respect to one bottle body w. Are arranged, and the glass material surface of the bottle body is scraped all at once by the abrasive, and frost-like processing (sand blasting) is performed. In this apparatus, five abrasive jetting units are arranged on all of the seven bottle bodies held by the bottle inverted holding unit. The position adjustment of the bottle body to be sandblasted and the individual injection units is optimally set in consideration of the size of the bottle body and the like.

  After this sandblasting process, the first partition 110 reaches the air blowing unit 160 and stops at the air blowing unit 160 for a predetermined time by further intermittently rotating by 120 °. In the meantime, the abrasive is sprayed by the abrasive spraying unit 150 and subjected to sandblasting, and blow air is sprayed onto the surface of the bottle. The blow air is blown for the purpose of removing abrasives adhering to the bottle surface and glass dust generated by the polishing. Similarly to the abrasive spraying device 155, the air spraying device 165 has a plurality of air injection portions (not shown) arranged in the vertical direction with respect to one bottle body w, and blow air is sprayed all at once. . A plurality of air injection sections are arranged on all of the seven bottle bodies held by the bottle inverted holding section. The position adjustment of the bottle body to which the air is blown and the individual air injection units are optimally set in consideration of the size of the bottle body.

  The bottle body which is held upside down by the bottle inverted holding part while the abrasive is sprayed by the abrasive spraying part 150 and while the blow air is being blown by the air spraying part 160 will be described in detail later in FIG. It can be rotated by movement. Thus, uneven spraying on the bottle surface is reduced.

  Since the same applies to the second bottle inverted holding portion 202 of the second partition 120 and the third bottle inverted holding portion 203 of the third partition 130, illustration and description thereof are omitted. As can be understood from the sections in the turntable 101, when the first section 110 is located in the carry-in / out section 140, the second section is located in the abrasive spraying section 150, and the third section is an air spraying section. 160. Next, when the 1st division part 110 is located in the abrasive spraying part 150, a 2nd division part is located in the air spraying part 160, and a 3rd division part is located in the carrying in / out part 140. FIG. And when the 1st division part 110 is located in the air spraying part 160, a 2nd division part is located in the carrying in / out part 140, and a 3rd division part is located in the abrasive spraying part 150. FIG.

  Thus, since the circulation between the carry-in / carry-out unit, the abrasive spraying unit, and the air spraying unit is possible by the intermittent rotation of the turntable, an untreated bottle can always be received in the abrasive spraying device. And it is always possible to perform sandblasting and blow air blowing on the bottle. Therefore, compared with the conventional sandblasting, it greatly contributes to the improvement of production efficiency per unit time.

  As defined in the invention of claim 2, the partition sections 110, 120, and 130 of the turntable 101 are partitioned and partitioned by a protective wall section 102 erected on the turntable. The protective wall 102 causes the abrasive sprayed from the abrasive spraying device 155 of the abrasive spraying part 150 to hit only the bottle body w of the partition part in the abrasive spraying part 150. Then, the abrasive is shielded so as not to diffuse to other compartments in the carry-in / carry-out unit 140 and the air blowing unit 160. This is because if the abrasive sprayed from the abrasive spraying device scatters to other compartments, it causes contamination of the device, and thus strictly shields the dust. In the figure, a partition wall 103 of the abrasive spraying apparatus 100 is also provided, and the abrasive spraying part 150 and the air spraying part 160 are partitioned to prevent the abrasives from being scattered.

  Further, a protective plate 105 is provided on the front side of the protective wall 102. The protective plate 105 is made of a soft material such as a mat (cushioning) made of resin such as polyurethane. The role of the protective plate portion 105 is to prevent the protective wall portion 102 itself from being worn by the abrasive material because the hardness of the abrasive material sprayed from the abrasive spraying device 155 is high.

  The abrasive after spraying, glass dust generated from the bottle surface, etc. are sucked through a suction duct 173 connected to a suction device 174 and collected (dust collection) as appropriate. The particle size is divided by a cyclone or the like, and is reused as an abrasive as necessary.

  The bottle inverted holding portions 200 (the first bottle inverted holding portion 201, the second bottle inverted holding portion 202, and the third bottle inverted holding portion 203 in this order) in each of the partition portions 110, 120, and 130 of the turntable 101 are arranged on the turntable 101. Arranged in a row. In the embodiment disclosed in FIG. 7, seven sections are arranged in a line on each partition. Since the first, second, and third bottle inverted holding parts have the same structure, the first bottle inverted holding part 201 is used as a representative, and FIGS. 7 and 8 are used to show the bottle inverted holding part (bottle holding part) of the turntable. ) Is explained.

A plurality of (seven in the embodiment) bases 210 are provided in a row in the bottle inverted holding portion 200 (201). A rotating pulley 300 that rotates the bottle body is connected to all of the seven bases 210 in one partition. Therefore, the entire turntable is provided with 21 bases and 21 rotating pulleys. Further, as shown in the drawing, an extension member actuating device 250 is disposed immediately below the rotation pulley. In the figure, reference numeral 108 denotes a rotating unit that intermittently rotates the turntable, and includes a motor (not shown). Reference numeral 211 denotes a support frame, 230 denotes an extension member, 251 denotes a guide rod, 252 denotes a pressing portion, and 255 denotes a driving portion.

  As can be understood from the enlarged view of the base portion of FIG. 8, the elastic head 220 and the extending member 230 are provided for any base 210 constituting the bottle inverted holding portion 200 (201, 202, 203). The elastic head 220 includes a rear attachment portion 225 attached to the base 210, a distal end portion 221 that can be inserted into the bottle mouth portion wo of the bottle body w, and a bag-like main body portion 222. The constituent material of the elastic head 220 is formed of a known resin material such as urethane rubber so as not to damage the bottle body. The rear mounting portion 225 of the embodiment also serves as a buffer member that comes into contact with the bottle mouth portion wo of the bottle body. This is to prevent the bottle mouth from being damaged by avoiding direct contact between the bottle body and the base 210. In addition to forming the distal end portion 221 and the bag-shaped main body portion 222 of the elastic head 220 from a single member, they may be formed by connecting or adhering both. The bag-like main body portion 222 of the embodiment has a spindle shape that is slightly swollen in the side surface direction when there is no action (normal time).

  In the embodiment, the cover body 205 is put on the base 210. The cover body 205 is connected to the base 210 on the turntable via the base covering member 206. Further, a side cover body 207 is disposed on the side surface of the base covering member 206. The cover body 205 and the side cover body 207 protect the base 210 from the abrasive sprayed from the abrasive spraying device 155 of the abrasive spraying section 150. This is to prevent abrasion of the base due to the abrasive and prevent the base from rotating. In addition, this is to prevent sandblasting from being performed on the bottle mouth portion. When the wear and damage of the cover body 205 and the side cover body 207 increase, they are removed from the base covering member 206 and replaced.

  A through hole 212 is formed in the center portion of the base 210 in the length direction of the elongated member 230. The extension member 230 is inserted into the through hole 212 and is inserted from the rear mounting portion 225 of the elastic head 220 into the elastic head (inside the bag-shaped main body 222). The distal end of the extending member 230 is in contact with the distal end portion 221. In the embodiment, a screw member is connected. A receiving portion 232 is attached to the lower end of the extending member, and is pushed up by the pressing portion 252.

  A spring 235 is interposed in a portion inserted through the through hole 212 of the extending member 230. An upper flange 231 and a lower flange 233 are attached above and below the spring 235. The spring 235 is pressed by the upper and lower flanges 231, 233, and a biasing force is generated to constantly extend the spring. Therefore, the extending member 230 is always urged downward, and the receiving portion 232 at the lower end of the extending member 230 is positioned in the lowered state.

  The base 210 and the rotation pulley 300 immediately below the base 210 are connected, and the base 210 is mounted on the turntable 101 via an appropriate rotation mechanism such as a ball bearing (ball bearing). The rotation of the rotation pulley 300 directly leads to the rotation of the base 210, and the bottle body held upside down by the elastic head 220 can be rotated. In the structure of the bottle inverted holding portion of the embodiment, the base covering member 206, the cover body 205, and the side cover body 207 are also rotated in accordance with the rotation of the base 210.

  When the elongating member 230 moves forward, that is, when the elongating member is raised, the front end 221 at the front end of the bag-like main body 222 is pushed out to elongate the bag-like main body 222. Normally, the extension member 230 is in the lowered position, and the bag-shaped main body 222 is pressed against the inner surface of the bottle mouth portion of the bottle mouth portion wo so that the bottle body w is supported. On the other hand, when the bag-shaped main body portion 222 is extended, the bag-shaped main body portion 222 is brought into non-pressure contact with the inner surface of the bottle mouth portion, and the bag-shaped main body portion 222 can be taken into and out of the bottle body.

  The illustrated extension member actuating device 250 is installed only directly below the turntable 101 located in the carry-in / carry-out unit 140 (see FIG. 5 and the like) of the abrasive spraying processing device 100. The extension member actuating device 250 is equipped with a drive unit 255 having a known air cylinder that is controlled to move up and down by compressed air. The movable platen 253 is disposed above the drive unit 255, and the pressing units 252 that are in contact with the extending member 230 (its receiving unit 232) are arranged on the movable platen 253 in the same number of seven rows as the base 210. .

  First, the turntable 101 is intermittently rotated, and one of the partition units 110, 120, and 130 is positioned in the carry-in / carry-out unit 140 (see FIGS. 2, 3, and 5) and stops. In the extension member actuating device 250, the pushing portion 252 is also raised as the movable platen 253 is raised by the operation of the driving portion 255. The extension member 230 of the bottle inverted holding part 200 (any one of 201, 202, 203) in the partition part is lifted by the pressing part 252 of the extension member actuating device 250. Therefore, all the extending members 230 (seven shown in FIG. 7 of the embodiment) advance (rise) all at once. As a result, the extending member 230 can extend and retract the bag-like main body 222 of the elastic head 220 into and out of the bottle body w. The movable platen 253 can be lifted while being kept horizontal by the guide rod 251.

  Like the bottle body holding mechanism disclosed in the embodiment, by providing the extension member with a spring, the shape deformation mechanism of the bag-like main body portion of the elastic head required for attaching and detaching (attaching and removing) the bottle body is simple. It can be a structure. At the same time, this can be done with a very simple operation. In addition, a plurality of glass bottles (bottle bodies) can be smoothly and continuously attached to and detached from the bottle inverted holding portion in the apparatus. Therefore, the productivity of the sandblasting process can be improved.

  FIG. 9 is an arrangement view of the arrangement of various pulleys including the rotation pulley 300 provided in the turntable 101 of the abrasive spraying apparatus 100 as seen from the upper surface side of the turntable. In the drawing, the first partition 110 is moved to the loading / unloading section 140, the second partition 120 is moved to the abrasive spraying section 150, and the third partition 130 is moved to the air spraying section 160 by intermittent rotation and stopped. In the first partition part 110, corresponding to the seven bases 210 (see FIG. 7 and the like) of the first bottle inverted holding part 201, the first partition part rotation pulleys 301, 302, 303, 304, 305, 306, and 307 are connected. A rotation belt 340 for rotating the pulleys simultaneously (the first partition portion rotation belt 341 in the first partition portion 110) is stretched over all of the first partition portion rotation pulleys 301 to 307. In the embodiment, the first partition part auxiliary pulleys 308 and 309 for adjusting the belt deflection and the first partition part transmission pulley 310 are provided in the first partition part 110 of the turntable 101. Then, as shown in the figure, the first partitioning portion rotating belt 341 is stretched so as to come into contact with ten pulleys below the first partitioning portion 110.

  Similarly, corresponding to the seven bases 210 of the second bottle inverted holding part 202, the second partition part rotation pulleys 311, 312, 313, 314, 315, 316, 317 are connected directly below the respective bases. The Second partition portion auxiliary pulleys 318 and 319 for adjusting belt deflection and a second partition portion transmission pulley 320 are also provided. The second partition portion rotation belt 342 is stretched so as to contact the ten pulleys of the second partition portion 120. Similarly, corresponding to the seven bases 210 of the third bottle inverted holding part 203, the third partition part rotation pulleys 321, 322, 323, 324, 325, 326, and 327 are connected directly below the respective bases. . Third partition portion auxiliary pulleys 328 and 329 for adjusting the deflection of the belt, and a third partition portion transmission pulley 330 are also provided. The third partition portion rotation belt 343 is stretched so as to come into contact with the ten pulleys of the third partition portion 130.

  The pulleys 301 to 310 of the first partition 110, the pulleys 311 to 320 of the second partition 120, and the pulleys 321 to 330 of the third partition 130 are rotatably connected to the lower surface side of the turntable 101. In accordance with the intermittent rotational movement of the turntable 101, the pulleys provided below the respective partitioning parts are rotated together with the partitioning parts directly above in the order of the carry-in / out part 140, the abrasive spraying part 150, and the air spraying part 160 (FIGS. 10 to 13). reference).

  FIGS. 10 to 13 are schematic views showing the arrangement of pulleys and the like provided immediately below the turntable 101 in the abrasive spraying apparatus 100, which are shown together with the rotation of the turntable. As understood from FIG. 10, the abrasive spraying unit 150 of the abrasive spraying processing apparatus 100 is provided with abrasive spraying part relay pulleys 354 and 355, and the air spraying part 160 of the apparatus 100 is connected to the air spraying part relay. Pulleys 356 and 357 are arranged. As defined in the invention of claim 3, a relay belt 345 is stretched over the abrasive spray relay pulleys 354, 355 and the air spray relay pulleys 356, 357, and the four relay pulleys of the embodiment are used. 354 to 357 can rotate in conjunction with each other.

  In the embodiment, a motor pulley 347 (see FIG. 14) is provided under the abrasive spraying part relay pulley 354, and a motor belt 346 is provided between the driving part M (a known motor or the like) and the motor pulley 347. Is passed. Thus, the abrasive spray relay pulley and the air spray relay pulley are connected to the drive unit M. The rotational force of the drive unit M is transmitted from the abrasive spraying unit relay pulley 354 to the remaining relay pulleys 355, 356, and 357 via the relay belt 345. The four relay pulleys are arranged in a trapezoidal shape when viewed from above.

  In the abrasive spraying part 150, the rotation belt of the rotation pulley can be brought into contact with the abrasive spraying part relay pulley, and the rotation belt of the rotation pulley can be brought into contact with the air spraying part relay pulley in the air spraying part 160. In addition, the abrasive spray relay pulley and the air spray relay pulley are arranged respectively. The turntable 101 is intermittently rotated through the rotating portion 108 (see FIG. 7), and the partition portions 110, 120, and 130 are positioned in order of the abrasive spraying portion 150 and the air spraying portion 160. Then, the rotation belt corresponding to the bottle inverted holding part 200 (201, 202, 203) of each partition located in the abrasive spraying part 150 or the air spraying part 160 becomes the abrasive spraying part relay pulley or the air spraying part relay pulley. The bottle body w in the partition part is configured to rotate in contact.

  When the direct rotation belt is brought into contact with the abrasive spraying part relay pulley or the air spraying part relay pulley, the rotational force can be directly transmitted to the relay pulley side. However, in the bottle body rotation mechanism 370 (see FIG. 14) of the illustrated embodiment, the rotation belt does not directly contact each relay pulley, and the intermediate belt 345, the transmission pulleys 310, 320, 330, etc. Contact. This is based on the arrangement of various pulleys under the turntable of the abrasive spraying processing device, so that the space directly under the turntable can be used effectively in the vertical direction and the rotational force can be easily transmitted through the belt and pulley. It is.

  Further, when the relay belt is omitted, a plurality of drive sources for individually rotating the relay pulley are required. For this reason, the manufacturing cost, operation cost, etc. of the abrasive spraying apparatus itself are likely to be expensive. In contrast, when a relay belt is used, the rotational force of one relay pulley can be easily transmitted to another relay pulley, and the burden of installing individual drive sources is reduced.

  In the embodiment of FIGS. 9 and 10, as defined in the invention of claim 4, each of the partition portions is provided with transmission pulleys 310, 320, and 330, and a rotating belt according to each partition portion. 340 (341, 342, 343) is also wound around the transmission pulleys 310, 320, 330 together with the rotation pulley 300 (301 to 307, 311 to 317, 321 to 327). Therefore, when one of the pulleys in contact with the rotation belt 340 (the first partition portion rotation belt 341, the second partition portion rotation belt 342, and the third partition portion rotation belt 343) of each partition portion rotates, the rotation is simple. Can be transmitted to other pulleys. In particular, in the configuration of the embodiment, the first partition portion transmission pulley 310 rotates the first partition portion rotation belt 341, the second partition portion transmission pulley 320 rotates the second partition portion rotation belt 342, and the third partition portion The transmission pulley 330 rotates the third partition portion rotation belt 343.

  Since the rotation pulley is rotated with the transmission pulley interposed as in the illustrated embodiment, the rotational force of the abrasive spraying part relay pulley or the air spraying part relay pulley is not directly transmitted to the individual rotation pulleys. That is, the impact of contact with the relay pulley can be reduced.

  FIG. 14 is a side view of the bottle body rotation mechanism 370 schematically showing the positional relationship of pulleys provided under the turntable 101. As can be understood from FIGS. 9, 10, and 14, and as defined in the invention of claim 5, passive pulleys (first passive pulley 351, second passive pulley 352, second 3 passive pulleys 353) are provided. The passive pulleys 351, 352, and 353 come into contact with the relay belt 345 stretched over the relay pulley (such as the abrasive spray relay relay pulley 354), so that the abrasive spray relay pulleys 354 and 355 or the air spray relay are relayed. The rotational force of the pulleys 356, 357 is transmitted to each of the passive pulleys 351, 352, 353. The first passive pulley 351 and the first partition part transmission pulley 310, the second passive pulley 352 and the second partition part transmission pulley 320, and the third passive pulley 353 and the third partition part transmission pulley 330 are connected coaxially. For this reason, the rotational force of the passive pulley is directly transmitted to the transmission pulley.

  The rotation pulleys 340 (the first partition portion rotation belt 341 and the second partition) are respectively connected to the transmission pulleys of each partition portion (the first partition portion transmission pulley 310, the second partition portion transmission pulley 320, and the third partition portion transmission pulley 330). A part rotation belt 342 and a third partition part rotation belt 343). In each partition part, the individual rotation pulleys (see FIG. 9) can rotate through the transmission pulleys.

  Further, as shown in the illustrated embodiment, since the rotation pulley is rotated by interposing a passive pulley, the rotational force of the abrasive spray relay relay pulley or the air spray relay relay is not directly transmitted to the individual rotation pulleys. Thus, the impact of contact with the relay pulley can be reduced. In addition, since the various pulleys under the turntable are arranged in the vertical direction, the space under the turntable can be used effectively.

  Next, changes in the contact state between the passive pulley and the relay belt accompanying the movement of the turntable will be described mainly based on the rotational movement of the first partition portion, using the schematic top views of FIGS. 10 to 13. In the figure, the pulleys 301 to 310, 311 to 320, and 321 to 330 of each partition section that rotate and move in conjunction with the turntable are indicated by broken lines, and the rotation belts 341, 342, and 343 that are stretched around these pulleys are shown as one point. Indicated by a chain line.

  FIG. 10 shows the arrangement of various pulleys and belts spanned around the pulleys when the first partition 110 is positioned in the carry-in / carry-out unit 140 due to the intermittent rotational movement of the turntable 101. When the first partition 110 of the turntable 101 is positioned at the loading / unloading unit 140 and stopped, as described above, the bottle body is attached to the elastic head 220 of the bottle inverted holding unit 200 (first bottle inverted holding unit 201). w is inverted and inserted and withdrawn from here. Therefore, in the carry-in / carry-out unit 140, it is not necessary to rotate the base of the bottle inverted holding unit of the first partition unit 110. As shown in FIG. 10, the first passive pulley 351 (the first partition part transmission pulley 310 immediately above it) is not in contact with any of the relay belt 345, the abrasive spraying part relay pulley, or the air spraying part relay pulley. The rotation pulleys 301 to 307 in the partition 110 do not rotate.

  As can be seen from FIG. 10, the second partition 120 is positioned and stopped at the abrasive spraying portion 150, and the third partition 130 is positioned and stopped at the air spraying portion 160. The second passive pulley 352 of the second partition 120 (the second partition transmission pulley 320 immediately above it) is in contact with the relay belt 345, and the third passive pulley 353 of the third partition 130 (the third directly above the third pulley pulley 353). The partition part transmission pulley 330) is also in contact with the relay belt 345. Accordingly, the rotation pulleys 311 to 317 of the second partition 120 and the rotation pulleys 321 to 327 of the third partition 130 rotate in conjunction with the contact with the relay belt 345 driven through the abrasive spray relay relay 354. .

  As described with reference to FIGS. 2, 6, etc., abrasive is sprayed from the abrasive spraying device 155 in the abrasive spraying unit 150, and blown air is sprayed from the air spraying device 165 in the air spraying unit 160. By rotating the bottle body on the spot, the amount of abrasive and blow air sprayed onto the bottle surface becomes uniform. As a result, the non-uniformity of polishing associated with the sandblasting process and the non-uniformity of dust blown off from the bottle surface accompanying the polishing are greatly reduced.

  FIG. 11 shows a state in which the turntable 101 rotates 45 ° clockwise from FIG. 10 and the first partition 110 is moving from the carry-in / carry-out unit 140 to the abrasive spraying unit 150. The second and third partition sections 120 and 130 are also moving. As the turntable 101 rotates, the second passive pulley 352 and the like of the second partition unit 120 also rotate. In this case, the second passive pulley 352 blows air from the abrasive spraying part 150 while biting into the relay belt 345 stretched around the abrasive spraying part relay pulleys 354 and 355 and the air spraying part relay pulleys 356 and 357. Rotate to section 160. Further, the second passive pulley 353 is released from the contact with the relay belt 345 and is on the way to the carry-in / carry-out unit 140. As shown in the figure, even if the relay belt 345 is pressed by a pulley, the relay belt 345 can absorb bending because it has elasticity. Further, since the relay pulley is configured so that the position can be adjusted, it can cope with the bending deformation of the relay belt.

  FIG. 12 shows a state in which the turntable 101 is rotated 90 ° clockwise from FIG. 10 and the first partition part 110 enters the abrasive spraying part 150. The second and third partition sections 120 and 130 are also moving. As the turntable 101 rotates, the first passive pulley 351 of the first partition 110 starts to come into contact with the relay belt 345 stretched over the relay pulleys 354 to 357. The second passive pulley 352 of the second partition unit 120 is rotating and moving to the air blowing unit 160 while being in contact with the relay belt 345.

  FIG. 13 shows a state in which the turntable 101 is rotated 120 ° clockwise from FIG. 10 and the first partition 110 reaches a predetermined position of the abrasive spraying unit 150 and stops. Both the first passive pulley 351 of the first partition 110 and the second passive pulley 352 of the second partition 120 are in contact with the relay belt 345. At this time, when the relay belt 345 is driven through the rotation of the abrasive spray relay relay pulley 354, both the first passive pulley 351 and the second passive pulley 352 that are in contact with the relay belt 345 are simultaneously driven to rotate. All of the rotation pulleys 301 to 307 of the first partition 110 and the rotation pulleys 311 to 317 of the second partition 120 rotate at the same time, and the bottle bodies w held in the individual bottle inverted holders rotate. Since the third partition 130 in FIG. 13 is stopped at the carry-in / carry-out unit 140, the third passive pulley 353 does not contact the relay belt 345 and the rotation pulley does not rotate.

  In the illustrated embodiment, the state of the intermittent rotational movement of the first partition portion is shown while compensating for the movement. Since the arrangement and structure of the members of each partition are all the same, the contact between the pulley and the belt is the same even when the second partition and the third partition are intermittently moved, and the description thereof is omitted. The various pulleys and the number of the pulleys in the bottle body rotation mechanism of the disclosed abrasive spraying apparatus, and the configuration of the belts, etc., spanned over the pulleys are appropriately determined within the scope of the invention according to the size and processing capacity of the apparatus. It can be modified and assembled.
