Description

  The present invention relates to 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.

Further, both cross moving parts 13 are provided with an elevating part 14 for moving a chuck unit, which will be described later, up and down (Z) (see FIG. 4 and the like). A servo motor or the like is provided as a known control motor for driving the parallel moving unit 12, the cross moving unit 13, and the elevating unit 14 and controlling the moving amount.

  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. 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. FIG. 6 is an enlarged view of an example of the chuck portion 21. One chuck portion 21 is provided with a frame portion 24 and press contact portions 22 and 23 for gripping the bottle body side surfaces from two opposite directions. The pressure contact portions 22 and 23 can be held and detached by moving back and forth within the frame portion 24. It is also possible to constitute the chuck portion only from the pressure contact portions 22 and 23 by omitting the frame portion 24. 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.

  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 device, In the drawing, the first partitioning unit 110 is positioned immediately above the first bottle inverted holding unit 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 device, in the drawing, the first partition portion. The first bottle inverted holding portion 201 (200) at 110 is aligned directly above.

  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 when the turntable 101 is intermittently rotated and one of the partition portions is stopped at the opening 109.

  The abrasive spraying part 150 and the air spraying part 160 of the abrasive spraying apparatus 100 of an Example are demonstrated using FIG.1 and FIG.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. 7, 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.

  Since the same applies to the second bottle inverted holding unit 202 in the second partition unit 120 and the third bottle inverted holding unit 203 in the third partition unit 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 portion 102 allows the abrasive sprayed from the abrasive spraying device 155 (the abrasive spraying portion) of the abrasive spraying portion 150 to hit only the bottle body w of the partition portion in the abrasive spraying portion 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 device 100 is also provided, and the abrasive spraying unit 150 and the air spraying unit 160 are partitioned to prevent the abrasive from being scattered.

  Further, as defined in the invention of claim 3, a protective plate portion 105 is provided on the front side of the protective wall portion 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.
