JP 2003-36471 A Japanese Patent Laid-Open No. 10-247276

  However, in the conventional apparatus in which the guide wall member 60 'is a simple plate-shaped sheet metal member, the impact sound when the product 3 falling in the product storage passage S collides with the guide wall member 60' is large. There was a problem that many annoying high frequency sound components were generated.

  In addition, in the conventional apparatus in which the column body is made of resin, the impact sound can be mitigated and the generation of high-frequency sound components can be suppressed by the sound absorption (attenuation) property of the resin material, but the impact sound is still loud. There was a problem.

  In view of this situation, the main problem of the present invention is to effectively reduce the impact sound by rational improvement to the guide wall member.

The first characteristic configuration of the present invention includes: a lower support means for receiving and supporting a lowermost product at a lower end portion of a product storage passage for stacking and storing a plurality of products in a state where the plurality of products can be paid downward; An upper support means for receiving and supporting the second product from the bottom when releasing the product support and paying out the product, and receiving the product second from the bottom and receiving the product located at the bottom Establish a product delivery mechanism that delivers
In the product storage device of the vending machine in which the lower end portion of the product storage passage is formed by this product delivery mechanism and the guide wall member opposed thereto,
The guide wall member is formed of a synthetic resin molded product including a front wall portion that forms a guide surface on the commodity storage passage side , and a plurality of through holes are dispersed in the wall surface view to the front wall portion . Forming ,
The guide wall member includes a plurality of ribs that extend from the front wall portion to the opposite side of the product storage passage and are arranged in a lattice shape in a wall surface view,
Forming a guide projection on the front wall portion that bulges toward the product delivery mechanism in a side view and guides the product toward the product delivery mechanism, and in which the through hole is not formed,
Among the plurality of through-holes formed in the front wall portion, through-holes formed in other portions with through-holes formed so as to be aligned along the guide protrusions in the upper vicinity portion and the lower vicinity portion of the guide protrusion Formed in a hole with a larger opening area than
In the guide wall member, the number of the ribs formed in the upper vicinity portion and the lower vicinity portion of the guide protrusion is larger than the number of the ribs formed in the other portion .

According to the first characteristic configuration, the impact sound can be reduced by the sound absorption (attenuation) provided by the synthetic resin, and the area of the sound generation portion in the guide wall member can be reduced by the plurality of through holes to reduce the impact sound. The emissivity can be reduced, and it is possible to obtain a silencing effect due to a phase shift between the sound propagating from the guide wall member without passing through the through hole and the sound propagating from the guide wall member through the through hole. By reducing the weight by forming the holes, the impact force itself at the time of collision with the product can be reduced, and in combination, the impact sound caused by the collision between the product and the guide wall member can be effectively reduced.

  Further, by making the guide wall member made of synthetic resin, it is possible to effectively suppress the generation of annoying high frequency sound component, and it is possible to make the sound more effective audibly.

Furthermore, before a plurality of ribs disposed in a grid with being extended wall seen on the opposite side from the wall portion and the product storage passage, products of the front wall portion when colliding with the front wall of the guide wall member The overall large vibration can be effectively suppressed, and the guide wall member is lighter compared to the case where the overall large vibration is suppressed by replacing the rib with a thick plate structure. Thus, the impact force itself at the time of collision with the product can be reduced, and these, combined with the above-described effect of reducing the impact sound by the synthetic resin and the effect of reducing the impact sound by the through hole, result in the product and the guide wall member. The impact sound due to the collision with can be effectively reduced.
By the way, since the guide protrusion bulges toward the product dispensing mechanism (that is, the inside of the product storage passage), the collision frequency with the product is higher than that of the other part of the guide wall member. Although the impact force is concentrated compared to other parts, among the plurality of through holes formed in the front wall part, through holes formed so as to be aligned along the guide protrusions in the upper vicinity part and the lower vicinity part of the guide protrusion, According to the first characteristic configuration formed in the hole having a larger opening area than the through hole formed in the other part, the impact sound emissivity in the vicinity of the guide protrusion is effectively reduced by the through hole having the large opening area. Thus, it is possible to effectively reduce the impact sound caused by the collision between the product and the guide projection, thereby further reducing the impact sound caused by the collision between the product and the guide wall member.
In addition, if all the through holes formed in the front wall portion of the guide wall member that are dispersed in the wall surface view are formed in the holes having a large opening area, there is a risk of catching the product, but the product has a function of delivering the product. A through hole that is formed to be aligned along the guide protrusion is formed in a portion near the upper and lower portions of the guide protrusion that is guided toward the side, and a hole having a large opening area is formed. If it is the said structure formed in a hole, derivative problems, such as catching of goods, can also be avoided.

According to a second characteristic configuration of the present invention, in the first characteristic configuration, the through hole formed in the other part excluding the upper vicinity part and the lower vicinity part of the guide protrusion is formed in a circular shape, and the upper vicinity part of the guide protrusion And the through hole formed in the lower vicinity is formed in a rectangular shape .

  In the product storage device of the vending machine shown in FIG. 1, a plurality of products 3 such as beverage cans, beverage bottles, and plastic bottles can be dispensed downward into the product storage 2 of the cabinet A surrounded by the heat insulating wall 1. Two of the product storage column units U, in which a plurality of product storage columns with product storage passages S for stacking and storing in a horizontal posture in the horizontal direction in the state are formed in the front-rear direction, are suspended from the front-rear direction. In the front of each product storage column, a product insertion port 4 for introducing the product 3 is formed in the upper part of the product storage passage S. In the lower part of each product storage passage S, A product delivery mechanism B as shown in FIG. 20 is provided for delivering the products 3 positioned at the bottom end one by one while receiving the products 3 positioned second from the bottom end based on the product delivery command signal (sales command signal). It has been.

  Further, among the product storage passages S of each product storage column, in order to connect them obliquely between the upper part of the product storage passage S located in the second and subsequent rows from the front and the corresponding product input port 4 The product introduction guides 5 that form the inclined introduction passages S1 are provided, and each product introduction guide 5 is formed in an inclined posture that is positioned slightly downward toward the back side. While moving down or rolling on the inclined bottom plate 5A of the product introduction guide 5 installed between the side plates 6, the product is introduced into the upper part of the product storage passage S, and the product delivery mechanism B is moved down in a meandering manner in the product storage passage S. It is conveyed to the side.

  Of the product storage passages S of the product storage columns, the entrance of each product storage passage S located in the second and subsequent rows from the front is slid down along the inclined introduction passage S1, as shown in FIGS. A posture correction plate 7 having a substantially "<" shape in side view that abuts the supplied product 3 and corrects the loading posture thereof, swings the seesaw around the lateral axis X1 as the product 3 passes through. Each posture correction plate 7 is formed of a synthetic resin perforated plate having a large number of through holes 7b penetrating in the thickness direction, and in the present embodiment, a plurality of vertical beams 7A and horizontal beams 7B are provided. Are integrally formed of a synthetic resin (POM) having elasticity in a lattice shape combining the above.

  Therefore, an impact sound is generated when the product 3 sliding down or rolling along the inclined introduction passage S1 contacts the posture correcting plate 7, but the posture correcting plate 7 is formed into a lattice shape with a synthetic resin having elasticity. Therefore, the sound absorption (attenuation) effect is higher than that of sheet metal, and the spring effect is easily exhibited because the elastic modulus is low and the toughness is high. In addition, the vibration generated by this collision is transmitted through the plurality of vertical bars 7A and the plurality of horizontal bars 7B, but there are few plane parts that cause resonance vibration, and the emissivity of the collision sound is reduced, so the impact sound is effectively reduced. can do.

  In particular, there are few high-frequency sound components that are harsh to human hearing compared to conventional posture correction plates made of sheet metal, and the main parts of those components concentrate in a relatively low frequency band that is more friendly to the ears, so sound pressure measurement It is possible to obtain human tranquility beyond the value.

  As product storage passage S, as shown in FIGS. 9 and 10, product storage passage S having a wide passage width W capable of storing a plastic bottle and product having a narrow passage width W dedicated to a can as shown in FIG. There are two types of storage passages S, and the product storage passage S with a wide passage width W has a product storage in order to change the passage width W according to the length of the storage product 3 (plastic bottle or can). A width adjusting plate (not shown) having a length extending from near the upper end to the lower end of the passage S is disposed so as to be movable and operable in a parallel or substantially parallel posture in the passage width direction.

  As shown in FIGS. 9 to 11, the guide plate forming the product storage passage S includes a long fixed guide plate 8 corresponding to the product storage passage S having a wide passage width W, and a product storage passage having a narrow passage width W. A short fixed guide plate 9 corresponding to S and a movable guide as a common part that can be selectively provided on the right or left side of the front surface of the long fixed guide plate 8 or on the front surface of the short fixed guide plate 9. Each of the guide plates 8, 9, 10 is composed of a synthetic resin porous plate provided with a large number of through-holes 8a, 9a, 10a penetrating in the plate thickness direction. Are integrally formed of a synthetic resin (POM) having elasticity in a lattice shape combining the vertical bars 8A, 9A, 10A and the horizontal bars 8B, 9B, 10B.

  Therefore, when the introduced product 3 collides with the fixed guide plates 8 and 9 and the movable guide plate 10 constituting the product storage passage S, vibration caused by the collision causes the fixed guide plates 8 and 9 and the movable guide plate 10 to move. Since it is propagated to the plurality of vertical bars 8A, 9A, and 10A and the horizontal bars 8B, 9B, and 10B, the emissivity of the impact sound is reduced, the plane portion that causes resonance vibration is reduced, and it has elasticity. Since it is integrally molded in a lattice shape with synthetic resin, it has a high sound absorption (attenuation) effect, and since it has a low elastic modulus and high toughness, it is easy to exert a spring effect. Alternatively, the hitting sound can be effectively reduced.

  Furthermore, since the number of the horizontal bars 8B, 9B, 10B constituting the fixed guide plates 8, 9 and the movable guide plate 10 is smaller than the number of the vertical bars 8A, 9A, 10A, it is generated due to a collision with the product 3 or a blow. It is difficult for the generated vibration to be propagated in the lateral direction, and it is possible to effectively suppress the generation of sound due to vibration of the entire sheet metal side plates 6 constituting the product storage column.

  As shown in FIGS. 4 and 9 to 12, on the upper edge portion of the long fixed guide plate 8, a synthetic resin made between the left and right side plates 6 forming the product storage passage S having a wide passage width W is formed. The horizontal mounting portion 8C is integrally formed, and is also formed on the upper edge of the short fixed guide plate 9 between the left and right side plates 6 forming the product storage passage S with a narrow passage width W. A horizontal mounting portion 9C is integrally formed. The horizontal mounting portions 8C and 9C can be inserted into mounting holes 11 provided in the left and right side plates 6 and are inserted to a predetermined insertion depth. In this case, there is provided insertion connecting means C that engages with the side plate 6 at the periphery of the mounting hole 11 (see FIG. 19) and prevents the fixed guide plates 8 and 9 from moving in the left-right direction.

  Then, a long fixed guide plate 8, a short fixed guide plate 9, a guide plate unit (see FIG. 9) in which a movable guide plate 10 is swingably mounted on the front right side of the long fixed guide plate 8, and a long fixed A guide plate unit (see FIG. 10) having a movable guide plate 10 swingably mounted on the left side of the front surface of the guide plate 8, and a movable guide plate 10 swingably mounted on the front surface of the short fixed guide plate 9. A guide plate unit (see FIG. 11) is manufactured, and the parts selected in accordance with the form of the product storage passage S are slightly larger than the maximum length of the product 3 to be stored as shown in FIGS. In a state where the left and right side plates 6 fixedly connected at intervals are opposed to each other at intervals in the front-rear direction, and the heights of the guide plates opposed in the front-rear direction are positioned half pitch apart from each other Each product can be stored by erection Forming a road S meanders, it is to be relaxed drop impact during product replenished by the meandering.

  Further, on the lower side of each product storage passage S and near the upper portion of the product delivery mechanism B, in order to detect the presence or absence of the product 3 in the product storage passage S, outside the passage width changing operation area of the width adjusting plate A sold-out detection plate (sold-out flapper) 12 that is urged and urged by an elastic force is provided in the product storage passage portion so as to be swingable around a lateral axis on the upper end side thereof.

  Of the plurality of guide plates 8, 9, 10 that are arranged side by side in the vertical direction to form the product storage passage S, the guide plate 10 that is positioned at the top of the product storage passage S in a state of facing the product insertion port 4, Although it is a movable guide plate that can swing around the lateral axis X2 at the upper end of the long fixed guide plate 8 or the short fixed guide plate 9 and is urged and projected into the product storage passage S by a torsion spring 16. On the other hand, the posture correction plate 7 is disposed so that the lower end portion 7d of the posture correction plate 7 comes into contact with the upper and lower central portions of the movable guide plate 10 that is projected and urged into the product storage passage S. 10 is oscillated and biased toward the contact side.

  That is, as shown in FIG. 2 and FIG. 3, when the product 3 that has slid down or rolled along the inclination introduction passage S <b> 1 is guided into the product storage passage S while pushing the lower half of the posture correction plate 7. Since the movable guide plate 10 that is in contact with the lower end 7d of the posture correction plate 7 is also retracted and rocked against the protruding biasing force of the torsion spring 16, the product 3 is postured due to the rotational deceleration action by the retraction rocking. The impact force when colliding with the lower half portion of the correction plate 7 can be effectively attenuated, and the generation of impact sound can be suppressed.

Since the fixed guide plate 9 can be received by the plurality of vertical bars 9A having a large vertical bending strength, the deformation and breakage of the movable guide plate 10 are surely prevented.

  The stopper pieces 17f provided on the long fixed guide plate 8 and the short fixed guide plate 9 are provided on the movable guide plate 10 which moves between the longitudinal bars 8A and 9A of the long fixed guide plate 8 and the short fixed guide plate 9 and moves. Before the lower horizontal beam 10B comes into contact with the lower horizontal beam 8B, 9B of each fixed guide plate 8, 9, the upper side of the vertical beam 10A of the movable guide plate 10 is elastically contacted from the back side, and this contact is made. By the contact, the maximum entry position of the vertical beam 10A of the movable guide plate 10 between the vertical beams 8A and 9A in the long fixed guide plate 8 and the short fixed guide plate 9 is regulated.

  Therefore, as shown in FIGS. 4 to 8, when the product 3 falling in the product storage passage S collides with the movable guide plate 10, the lower half side portion of the vertical rail 10 </ b> A of the movable guide plate 10 is The movable guide plate moves rapidly between the longitudinal bars 8A and 9A of the long fixed guide plate 8 and the short fixed guide plate 9 while retreating and swinging against the protruding biasing force of the torsion spring 16 from the swinging direction. It is possible to prevent the lower end portion of 10 from coming into contact with the lower end portions of the long fixed guide plate 8 and the short fixed guide plate 9 by the stopper piece 17f, so that a large hitting sound is not generated. In addition, since the stopper piece 17f is elastically deformed as it comes into contact with the upper side of the vertical rail 10A of the movable guide plate 10, the impact vibration generated when the swing of the movable guide plate 10 is stopped is effectively prevented. Attenuation can suppress the generation of sound.

  In order to allow the vertical beam 10A of the movable guide plate 10 to enter between the vertical beams 8A and 9A of the long fixed guide plate 8 or the short fixed guide plate 9, the movable guide plate 10 is adjacent to the vertical beam 10A. The distance d1 (the width of the slit-shaped gap 10a) needs to be slightly larger than the lateral width w2 of the vertical rails 8A and 9A in the long fixed guide plate 8 and the short fixed guide plate 9, respectively. The horizontal width w2 of the vertical bars 8A and 9A of each of the 8 and the short fixed guide plate 9 is smaller than the horizontal width w1 of the vertical bar 10A of the movable guide plate 10, and thereby the vertical beam 10A of the movable guide plate 10 is reduced. The adjacent space d1 is made as small as possible, and the area occupied by the nine vertical bars 10A in the movable guide plate 10 is made as large as possible.

  That is, by reducing the adjacent distance d1 between the vertical rails 10A of the movable guide plate 10 as much as possible, the corner of the product 3 descending in the product storage passage S (the corner between the end surface and the peripheral surface) is the product. The movable guide plate 10 that protrudes inwardly from the storage passage S is prevented from getting caught between the vertical bars 10A, and the product 3 is placed in the product storage passage S due to the catch. In this case, it is possible to effectively prevent the troubled stacked storage state of the oblique vertical posture.

  It should be noted that the vertical width of the movable guide plate 10 is increased as shown in FIG. 18 while the horizontal width w1 of the vertical beam 10A of the movable guide plate 10 is increased to reduce the adjacent distance d1 between the vertical bars 10A of the movable guide plate 10. A through hole is formed in 10A as a plurality of through holes 10e such as circles and squares or slits extending in the longitudinal direction of the vertical beam 10A, and the area of the sound generating portion in each vertical beam 10A of the movable guide plate 10 is reduced. Thereby, the impact sound emissivity of the movable guide plate 10 with respect to the collision with the product 3 may be kept low, and the quietness may be kept high.

Next, the insertion connecting means C of the horizontal mounting portions 8C and 9C made of synthetic resin integrally formed with the long fixed guide plate 8 and the short fixed guide plate 9 will be described.
As shown in FIG. 12 and FIG. 19, at both ends of the horizontal mounting portions 8C and 9C of the long fixed guide plate 8 and the short fixed guide plate 9, a lateral U-shape formed on the left and right side plates 6 or When the ends of the horizontal mounting portions 8C and 9C are inserted into the V-shaped mounting hole 11 from the left-right direction (passage width direction), the U-shaped or V-shaped bottom top side of the mounting hole 11 A pair of upper and lower convex portions 18a that abut the inner surface of the side plate 6 (surface facing the product storage passage S) at two hole peripheral portions a to define the insertion amount, and the convex portions 18a are the two locations described above. In the inserted state in which the hole peripheral portion a contacts the inner surface of the side plate 6, the tip of the hole peripheral portion b is located on the outer surface side of the side plate 6 at the hole peripheral portion b between the two hole peripheral portions a. Combined, the left and right direction of the horizontal mounting portions 8C, 9C by cooperation with the convex portion 18a Movement plan view "L" shaped horizontal bridging engagement pieces 18b that prevents the are integrally formed.

  When the end portions of the horizontal mounting portions 8C and 9C are inserted into the mounting holes 11, they are formed by elastically deformable side plate portions surrounded by the horizontal U-shaped or horizontal V-shaped mounting holes 11. The leading edge 6a of the retaining tongue piece 6A is in contact with or close to the back side of the horizontal engagement piece 18b, and the engagement state between the horizontal engagement piece 18b and the peripheral edge portion b of the side plate 6 is engaged. Is maintained.

  Further, among the vertical bars 8A and 9A of the fixed guide plates 8 and 9, the horizontal mounting portions 8C and 8A are mounted on the outer surface of the vertical bars 8A and 9A located on the left and right outer sides with respect to the mounting hole 11, respectively. When the end portion of 9C is inserted, it contacts the inner surface of the side plate 6 in the vicinity of the mounting hole 11, and the insertion amount of the end portions of the horizontal mounting portions 8C and 9C with respect to the mounting hole 11 together with the convex portion 18a is defined. The protrusions 19a are integrally formed, and the engaging protrusions 21a are inserted into the second mounting holes 20 formed in the left and right side plates 6 at the lower portions of the outer surfaces of the vertical bars 8A and 9A located on the left and right outer sides. In addition, in the state where the engaging protrusion 21 a is inserted into the second mounting hole 20, insertion restriction protrusions 21 b that come into contact with the inner surface of the side plate 6 at the two hole peripheral portions c of the second mounting hole 20 are integrally formed. Yes.

  Further, on the back side of the lower horizontal rails 8B and 9B of the fixed guide plates 8 and 9, side surfaces applied to the upper front portions of the horizontal mounting portions 8C and 9C of other guide plate units adjacent below. A concave portion 22 having an "L" shape is formed, and both ends of the horizontal mounting portions 8C and 9C are inserted and connected to the mounting holes 11, and the lower horizontal rails 8B and 8B of the fixed guide plates 8 and 9 are connected. The “L” -shaped concave portion 22 formed in 9B is surrounded by the second mounting hole 20 in a state where it is applied to the upper front portion of the horizontal mounting portions 8C and 9C of other guide plate units adjacent to the lower side. The distal end edge 6b of the second retaining tongue piece 6B formed by the elastically deformable side plate portion is configured to engage with the engaging surface of the engaging protrusion 21a.

  Therefore, when the engaging projections 21a of the fixed guide plates 8 and 9 are inserted and engaged with the second mounting holes 20 of the side plates 6, the vertical center portions of the vertical rails 8A and 9A are bent and deformed and engaged in that state. The protrusion 21a is inserted into and engaged with the second mounting hole 20, and as a result, the elastic restoring force of the vertical bars 8A and 9A is formed on the lower horizontal bars 8B and 9B of the fixed guide plates 8 and 9. Since the “L” -shaped concave portion 22 is pressed against the upper front portion of the horizontal mounting portions 8C and 9C in another guide plate unit adjacent to the lower side, noise such as a rattling sound caused by the mounting backlash is generated. Can be suppressed.

Further, the horizontal mounting portions 8C and 9C for laying the fixed guide plates 8 and 9 between the side plates 6 are integrally formed with the synthetic resin fixed guide plates 8 and 9, so that the horizontal mounting portions are formed. Compared with a sheet metal member that is different from the fixed guide plate, the number of parts can be reduced to facilitate manufacture and assembly, and the number of parts can be reduced to reduce backlash between members. Silencing can be promoted by obtaining the vibration absorbing function by the horizontal mounting portions 8C and 9C made of synthetic resin.

  At the lower end of each product storage passage S, the product storage passage S is formed in such a form that the product delivery mechanism B and the guide wall member 60 opposed to the product delivery mechanism B are the front and rear passage walls, and the product delivery mechanism B and the guide wall member Each of 60 is supported by being connected to both side plates 6 in a state of being spread over the left and right side plates 6 in the same manner as the fixed guide plates 8 and 9.

  The product dispensing mechanism B receives and supports the lowermost product 3 and the lower support unit B1 releases the product support when the lower support unit B1 releases the product 3 and delivers the second product 3 from the lowermost end. The upper support means B2 for receiving and supporting is assembled to the dispensing frame 61 to form a unit. When the product storage passages S are adjacent to each other, the unit of the product delivery mechanism B for each of the product storage passages S is assembled back to back. It has a structure.

  The guide wall member 60 that forms the product storage passage S together with the product delivery mechanism B has a triangular guide protrusion 60a that guides the product 3 toward the product delivery mechanism B and bulges toward the product storage passage S. Is formed.

  As for the product delivery mechanism B, similarly to the fixed guide plates 8 and 9, the product delivery mechanism B has a large width corresponding to the product storage passage S having a wide passage width W and a small width dimension corresponding to the product storage passage S having a narrow passage width W. There are two kinds of things. The guide wall member 60 also has a long guide wall member 60A having a large width corresponding to the product storage passage S having a wide passage width W as shown in FIGS. 21 to 23, and a product storage passage S having a narrow passage width W. A short guide wall member 60B as shown in FIGS. 24 to 26 having a small width dimension corresponding to the above is formed as an integrally molded product made of synthetic resin (POM).

  Each of the long guide wall member 60A and the short guide wall member 60B has a plate-like front wall portion 90 that forms a guide surface 90A on the product storage passage S side, and the front wall 90 in a posture orthogonal to the front wall portion 90. A rectangular flat box shape in front view comprising an upper outer wall portion 91A, both lateral outer wall portions 91B and a lower outer wall portion 91C extending from each of the four peripheral edges of the portion 90 to the back side (opposite to the product storage passage S). A large number of ribs 92a to 92c extending from the front wall portion 90 to the back side are integrally formed therein.

  As these ribs 92a to 92c, main ribs 92a and 92b whose extension length from the front wall portion 90 is the same as that of each of the outer wall portions 91A to 91C, and auxiliary ribs whose extension length is shorter than the main ribs 92a and 92b. The main ribs 92a and 92b are formed with a plurality of vertical main ribs 92a parallel to the lateral outer wall portion 91B at intervals in the left-right direction (the width direction of the product storage passage S). In addition, a plurality of horizontal main ribs 92b parallel to the upper outer wall portion 91A and the lower outer wall portion 91C are formed at intervals in the vertical direction, and the main ribs 92a and 92b are formed in a vertical and horizontal lattice shape when viewed from the front (ie, viewed from the wall surface). It is arranged in.

  The auxiliary ribs 92c are formed by forming a plurality of vertical ribs parallel to the lateral outer wall portion 91b at intervals in the left-right direction, and arranging the auxiliary ribs 92c in a vertical lattice shape when viewed from the front. Are arranged between the longitudinal main ribs 92a or between the longitudinal main ribs 92a and the lateral outer wall portion 91B. The front wall 90 is formed with a large number of through holes 93a and 93b at positions where the ribs 92a to 92c are absent.

  In other words, by making the guide wall members 60A and 60B a molded product made of synthetic resin, the sound absorption (attenuation) provided by the synthetic resin reduces impact noise caused by the collision between the product 3 and the guide wall members 60A and 60B. In addition to suppressing the generation of harsh high frequency sound components, the front wall 90 when the product 3 collides with the front wall 90 of the guide wall members 60A and 60B by the ribs 92a to 92c arranged in a lattice pattern. , And a large number of through-holes 93a and 93b formed in the front wall portion 90 that are dispersed in the wall surface view to reduce the area of the sound generating portion in the front wall portion 90, thereby reducing the impact sound. By reducing the emissivity, the impact sound caused by the collision between the product 3 and the guide wall members 60A and 60B is more effectively reduced.
